### Installer tests
|
||||
|
||||
After a one-time setup, the Nix repository's GitHub Actions continuous integration (CI) workflow can test the installer each time you push to a branch.
|
||||
|
||||
Creating a Cachix cache for your installer tests and adding its authorization token to GitHub enables [two installer-specific jobs in the CI workflow](https://github.com/NixOS/nix/blob/88a45d6149c0e304f6eb2efcc2d7a4d0d569f8af/.github/workflows/ci.yml#L50-L91):
|
||||
|
||||
- The `installer` job generates installers for the platforms below and uploads them to your Cachix cache:
|
||||
- `x86_64-linux`
|
||||
- `armv6l-linux`
|
||||
- `armv7l-linux`
|
||||
- `x86_64-darwin`
|
||||
|
||||
- The `installer_test` job (which runs on `ubuntu-latest` and `macos-latest`) will try to install Nix with the cached installer and run a trivial Nix command.
|
||||
|
||||
#### One-time setup
|
||||
|
||||
1. Have a GitHub account with a fork of the [Nix repository](https://github.com/NixOS/nix).
|
||||
2. At cachix.org:
|
||||
- Create or log in to an account.
|
||||
- Create a Cachix cache using the format `<github-username>-nix-install-tests`.
|
||||
- Navigate to the new cache > Settings > Auth Tokens.
|
||||
- Generate a new Cachix auth token and copy the generated value.
|
||||
3. At github.com:
|
||||
- Navigate to your Nix fork > Settings > Secrets > Actions > New repository secret.
|
||||
- Name the secret `CACHIX_AUTH_TOKEN`.
|
||||
- Paste the copied value of the Cachix cache auth token.
|
||||
|
||||
#### Using the CI-generated installer for manual testing
|
||||
|
||||
After the CI run completes, you can check the output to extract the installer URL:
|
||||
1. Click into the detailed view of the CI run.
|
||||
2. Click into any `installer_test` run (the URL you're here to extract will be the same in all of them).
|
||||
3. Click into the `Run cachix/install-nix-action@v...` step and click the detail triangle next to the first log line (it will also be `Run cachix/install-nix-action@v...`)
|
||||
4. Copy the value of `install_url`
|
||||
5. To generate an install command, plug this `install_url` and your GitHub username into this template:
|
||||
|
||||
```console
|
||||
sh <(curl -L <install_url>) --tarball-url-prefix https://<github-username>-nix-install-tests.cachix.org/serve
|
||||
```
|
||||
|
||||
<!-- #### Manually generating test installers
|
||||
|
||||
There's obviously a manual way to do this, and it's still the only way for
|
||||
platforms that lack GA runners.
|
||||
|
||||
I did do this back in Fall 2020 (before the GA approach encouraged here). I'll
|
||||
sketch what I recall in case it encourages someone to fill in detail, but: I
|
||||
didn't know what I was doing at the time and had to fumble/ask around a lot--
|
||||
so I don't want to uphold any of it as "right". It may have been dumb or
|
||||
the _hard_ way from the getgo. Fundamentals may have changed since.
|
||||
|
||||
Here's the build command I used to do this on and for x86_64-darwin:
|
||||
nix build --out-link /tmp/foo ".#checks.x86_64-darwin.binaryTarball"
|
||||
|
||||
I used the stable out-link to make it easier to script the next steps:
|
||||
link=$(readlink /tmp/foo)
|
||||
cp $link/*-darwin.tar.xz ~/somewheres
|
||||
|
||||
I've lost the last steps and am just going from memory:
|
||||
|
||||
From here, I think I had to extract and modify the `install` script to point
|
||||
it at this tarball (which I scped to my own site, but it might make more sense
|
||||
to just share them locally). I extracted this script once and then just
|
||||
search/replaced in it for each new build.
|
||||
|
||||
The installer now supports a `--tarball-url-prefix` flag which _may_ have
|
||||
solved this need?

# Arguments and Variables
|
||||
|
||||
The [Nix expression for GNU Hello](expression-syntax.md) is a
|
||||
function; it is missing some arguments that have to be filled in
|
||||
somewhere. In the Nix Packages collection this is done in the file
|
||||
`pkgs/top-level/all-packages.nix`, where all Nix expressions for
|
||||
packages are imported and called with the appropriate arguments. Here
|
||||
are some fragments of `all-packages.nix`, with annotations of what
|
||||
they mean:
|
||||
|
||||
```nix
|
||||
...
|
||||
|
||||
rec { ①
|
||||
|
||||
hello = import ../applications/misc/hello/ex-1 ② { ③
|
||||
inherit fetchurl stdenv perl;
|
||||
};
|
||||
|
||||
perl = import ../development/interpreters/perl { ④
|
||||
inherit fetchurl stdenv;
|
||||
};
|
||||
|
||||
fetchurl = import ../build-support/fetchurl {
|
||||
inherit stdenv; ...
|
||||
};
|
||||
|
||||
stdenv = ...;
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
1. This file defines a set of attributes, all of which are concrete
|
||||
derivations (i.e., not functions). In fact, we define a *mutually
|
||||
recursive* set of attributes. That is, the attributes can refer to
|
||||
each other. This is precisely what we want since we want to “plug”
|
||||
the various packages into each other.
|
||||
|
||||
2. Here we *import* the Nix expression for GNU Hello. The import
|
||||
operation just loads and returns the specified Nix expression. In
|
||||
fact, we could just have put the contents of the Nix expression
|
||||
for GNU Hello in `all-packages.nix` at this point. That would be
|
||||
completely equivalent, but it would make `all-packages.nix` rather
|
||||
bulky.
|
||||
|
||||
Note that we refer to `../applications/misc/hello/ex-1`, not
|
||||
`../applications/misc/hello/ex-1/default.nix`. When you try to
|
||||
import a directory, Nix automatically appends `/default.nix` to the
|
||||
file name.
|
||||
|
||||
3. This is where the actual composition takes place. Here we *call* the
|
||||
function imported from `../applications/misc/hello/ex-1` with a set
|
||||
containing the things that the function expects, namely `fetchurl`,
|
||||
`stdenv`, and `perl`. We use inherit again to use the attributes
|
||||
defined in the surrounding scope (we could also have written
|
||||
`fetchurl = fetchurl;`, etc.).
|
||||
|
||||
The result of this function call is an actual derivation that can be
|
||||
built by Nix (since when we fill in the arguments of the function,
|
||||
what we get is its body, which is the call to `stdenv.mkDerivation`
|
||||
in the [Nix expression for GNU Hello](expression-syntax.md)).

||||

||||

||||

# Build Script
|
||||
|
||||
Here is the builder referenced from Hello's Nix expression (stored in
|
||||
`pkgs/applications/misc/hello/ex-1/builder.sh`):
|
||||
|
||||
```bash
|
||||
source $stdenv/setup ①
|
||||
|
||||
PATH=$perl/bin:$PATH ②
|
||||
|
||||
tar xvfz $src ③
|
||||
cd hello-*
|
||||
./configure --prefix=$out ④
|
||||
make ⑤
|
||||
make install
|
||||
```
|
||||
|
||||
The builder can actually be made a lot shorter by using the *generic
|
||||
builder* functions provided by `stdenv`, but here we write out the build
|
||||
steps to elucidate what a builder does. It performs the following steps:
|
||||
|
||||
1. When Nix runs a builder, it initially completely clears the
|
||||
environment (except for the attributes declared in the derivation).
|
||||
This is done to prevent undeclared inputs from being used in the
|
||||
build process. If for example the `PATH` contained `/usr/bin`, then
|
||||
you might accidentally use `/usr/bin/gcc`.
|
||||
|
||||
So the first step is to set up the environment. This is done by
|
||||
calling the `setup` script of the standard environment. The
|
||||
environment variable `stdenv` points to the location of the
|
||||
standard environment being used. (It wasn't specified explicitly
|
||||
as an attribute in Hello's Nix expression, but `mkDerivation` adds
|
||||
it automatically.)
|
||||
|
||||
2. Since Hello needs Perl, we have to make sure that Perl is in the
|
||||
`PATH`. The `perl` environment variable points to the location of
|
||||
the Perl package (since it was passed in as an attribute to the
|
||||
derivation), so `$perl/bin` is the directory containing the Perl
|
||||
interpreter.
|
||||
|
||||
3. Now we have to unpack the sources. The `src` attribute was bound to
|
||||
the result of fetching the Hello source tarball from the network, so
|
||||
the `src` environment variable points to the location in the Nix
|
||||
store to which the tarball was downloaded. After unpacking, we `cd`
|
||||
to the resulting source directory.
|
||||
|
||||
The whole build is performed in a temporary directory created in
|
||||
`/tmp`, by the way. This directory is removed after the builder
|
||||
finishes, so there is no need to clean up the sources afterwards.
|
||||
Also, the temporary directory is always newly created, so you don't
|
||||
have to worry about files from previous builds interfering with the
|
||||
current build.
|
||||
|
||||
4. GNU Hello is a typical Autoconf-based package, so we first have to
|
||||
run its `configure` script. In Nix every package is stored in a
|
||||
separate location in the Nix store, for instance
|
||||
`/nix/store/9a54ba97fb71b65fda531012d0443ce2-hello-2.1.1`. Nix
|
||||
computes this path by cryptographically hashing all attributes of
|
||||
the derivation. The path is passed to the builder through the `out`
|
||||
environment variable. So here we give `configure` the parameter
|
||||
`--prefix=$out` to cause Hello to be installed in the expected
|
||||
location.
|
||||
|
||||
5. Finally we build Hello (`make`) and install it into the location
|
||||
specified by `out` (`make install`).
|
||||
|
||||
If you are wondering about the absence of error checking on the result
|
||||
of various commands called in the builder: this is because the shell
|
||||
script is evaluated with Bash's `-e` option, which causes the script to
|
||||
be aborted if any command fails without an error check.

# Nix Expression Language
|
||||
|
||||
The Nix expression language is a pure, lazy, functional language. Purity
|
||||
means that operations in the language don't have side-effects (for
|
||||
instance, there is no variable assignment). Laziness means that
|
||||
arguments to functions are evaluated only when they are needed.
|
||||
Functional means that functions are “normal” values that can be passed
|
||||
around and manipulated in interesting ways. The language is not a
|
||||
full-featured, general purpose language. Its main job is to describe
|
||||
packages, compositions of packages, and the variability within packages.

||||

||||
This section presents the various features of the language.

```
|
||||
|
||||
This file is actually already in the Nix Packages collection in
|
||||
`pkgs/applications/misc/hello/ex-1/default.nix`. It is customary to
|
||||
place each package in a separate directory and call the single Nix
|
||||
expression in that directory `default.nix`. The file has the following
|
||||
elements (referenced from the figure by number):
|
||||
|
||||
1. This states that the expression is a *function* that expects to be
|
||||
called with three arguments: `stdenv`, `fetchurl`, and `perl`. They
|
||||
are needed to build Hello, but we don't know how to build them here;
|
||||
that's why they are function arguments. `stdenv` is a package that
|
||||
is used by almost all Nix Packages; it provides a
|
||||
“standard” environment consisting of the things you would expect
|
||||
in a basic Unix environment: a C/C++ compiler (GCC, to be precise),
|
||||
the Bash shell, fundamental Unix tools such as `cp`, `grep`, `tar`,
|
||||
etc. `fetchurl` is a function that downloads files. `perl` is the
|
||||
Perl interpreter.
|
||||
|
||||
Nix functions generally have the form `{ x, y, ..., z }: e` where
|
||||
`x`, `y`, etc. are the names of the expected arguments, and where
|
||||
*e* is the body of the function. So here, the entire remainder of
|
||||
the file is the body of the function; when given the required
|
||||
arguments, the body should describe how to build an instance of
|
||||
the Hello package.
|
||||
|
||||
2. So we have to build a package. Building something from other stuff
|
||||
is called a *derivation* in Nix (as opposed to sources, which are
|
||||
built by humans instead of computers). We perform a derivation by
|
||||
calling `stdenv.mkDerivation`. `mkDerivation` is a function
|
||||
provided by `stdenv` that builds a package from a set of
|
||||
*attributes*. A set is just a list of key/value pairs where each
|
||||
key is a string and each value is an arbitrary Nix
|
||||
expression. They take the general form `{ name1 = expr1; ...
|
||||
nameN = exprN; }`.
|
||||
|
||||
3. The attribute `name` specifies the symbolic name and version of
|
||||
the package. Nix doesn't really care about these things, but they
|
||||
are used by for instance `nix-env -q` to show a “human-readable”
|
||||
name for packages. This attribute is required by `mkDerivation`.
|
||||
|
||||
4. The attribute `builder` specifies the builder. This attribute can
|
||||
sometimes be omitted, in which case `mkDerivation` will fill in a
|
||||
default builder (which does a `configure; make; make install`, in
|
||||
essence). Hello is sufficiently simple that the default builder
|
||||
would suffice, but in this case, we will show an actual builder
|
||||
for educational purposes. The value `./builder.sh` refers to the
|
||||
shell script shown in the [next section](build-script.md),
|
||||
discussed below.
|
||||
|
||||
5. The builder has to know what the sources of the package are. Here,
|
||||
the attribute `src` is bound to the result of a call to the
|
||||
`fetchurl` function. Given a URL and a SHA-256 hash of the expected
|
||||
contents of the file at that URL, this function builds a derivation
|
||||
that downloads the file and checks its hash. So the sources are a
|
||||
dependency that like all other dependencies is built before Hello
|
||||
itself is built.
|
||||
|
||||
Instead of `src` any other name could have been used, and in fact
|
||||
there can be any number of sources (bound to different attributes).
|
||||
However, `src` is customary, and it's also expected by the default
|
||||
builder (which we don't use in this example).
|
||||
|
||||
6. Since the derivation requires Perl, we have to pass the value of the
|
||||
`perl` function argument to the builder. All attributes in the set
|
||||
are actually passed as environment variables to the builder, so
|
||||
declaring an attribute
|
||||
|
||||
```nix
|
||||
perl = perl;
|
||||
```
|
||||
|
||||
will do the trick: it binds an attribute `perl` to the function
|
||||
argument which also happens to be called `perl`. However, it looks a
|
||||
bit silly, so there is a shorter syntax. The `inherit` keyword
|
||||
causes the specified attributes to be bound to whatever variables
|
||||
with the same name happen to be in scope.

# Generic Builder Syntax
|
||||
|
||||
Recall that the [build script for GNU Hello](build-script.md) looked
|
||||
something like this:
|
||||
|
||||
```bash
|
||||
PATH=$perl/bin:$PATH
|
||||
tar xvfz $src
|
||||
cd hello-*
|
||||
./configure --prefix=$out
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
The builders for almost all Unix packages look like this — set up some
|
||||
environment variables, unpack the sources, configure, build, and
|
||||
install. For this reason the standard environment provides some Bash
|
||||
functions that automate the build process. Here is what a builder using
|
||||
the generic build facilities looks like:
|
||||
|
||||
```bash
|
||||
buildInputs="$perl" ①
|
||||
|
||||
source $stdenv/setup ②
|
||||
|
||||
genericBuild ③
|
||||
```
|
||||
|
||||
Here is what each line means:
|
||||
|
||||
1. The `buildInputs` variable tells `setup` to use the indicated
|
||||
packages as “inputs”. This means that if a package provides a `bin`
|
||||
subdirectory, it's added to `PATH`; if it has a `include`
|
||||
subdirectory, it's added to GCC's header search path; and so on.
|
||||
(This is implemented in a modular way: `setup` tries to source the
|
||||
file `pkg/nix-support/setup-hook` of all dependencies. These “setup
|
||||
hooks” can then set up whatever environment variables they want; for
|
||||
instance, the setup hook for Perl sets the `PERL5LIB` environment
|
||||
variable to contain the `lib/site_perl` directories of all inputs.)
|
||||
|
||||
2. The function `genericBuild` is defined in the file `$stdenv/setup`.
|
||||
|
||||
3. The final step calls the shell function `genericBuild`, which
|
||||
performs the steps that were done explicitly in the previous build
|
||||
script. The generic builder is smart enough to figure out whether
|
||||
to unpack the sources using `gzip`, `bzip2`, etc. It can be
|
||||
customised in many ways; see the Nixpkgs manual for details.
|
||||
|
||||
Discerning readers will note that the `buildInputs` could just as well
|
||||
have been set in the Nix expression, like this:
|
||||
|
||||
```nix
|
||||
buildInputs = [ perl ];
|
||||
```
|
||||
|
||||
The `perl` attribute can then be removed, and the builder becomes even
|
||||
shorter:
|
||||
|
||||
```bash
|
||||
source $stdenv/setup
|
||||
genericBuild
|
||||
```
|
||||
|
||||
In fact, `mkDerivation` provides a default builder that looks exactly
|
||||
like that, so it is actually possible to omit the builder for Hello
|
||||
entirely.

# Values
|
||||
|
||||
## Simple Values
|
||||
|
||||
Nix has the following basic data types:
|
||||
|
||||
- *Strings* can be written in three ways.
|
||||
|
||||
The most common way is to enclose the string between double quotes,
|
||||
e.g., `"foo bar"`. Strings can span multiple lines. The special
|
||||
characters `"` and `\` and the character sequence `${` must be
|
||||
escaped by prefixing them with a backslash (`\`). Newlines, carriage
|
||||
returns and tabs can be written as `\n`, `\r` and `\t`,
|
||||
respectively.
|
||||
|
||||
You can include the result of an expression into a string by
|
||||
enclosing it in `${...}`, a feature known as *antiquotation*. The
|
||||
enclosed expression must evaluate to something that can be coerced
|
||||
into a string (meaning that it must be a string, a path, or a
|
||||
derivation). For instance, rather than writing
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=" + freetype + "/lib"
|
||||
```
|
||||
|
||||
(where `freetype` is a derivation), you can instead write the more
|
||||
natural
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=${freetype}/lib"
|
||||
```
|
||||
|
||||
The latter is automatically translated to the former. A more
|
||||
complicated example (from the Nix expression for
|
||||
[Qt](http://www.trolltech.com/products/qt)):
|
||||
|
||||
```nix
|
||||
configureFlags = "
|
||||
-system-zlib -system-libpng -system-libjpeg
|
||||
${if openglSupport then "-dlopen-opengl
|
||||
-L${mesa}/lib -I${mesa}/include
|
||||
-L${libXmu}/lib -I${libXmu}/include" else ""}
|
||||
${if threadSupport then "-thread" else "-no-thread"}
|
||||
";
|
||||
```
|
||||
|
||||
Note that Nix expressions and strings can be arbitrarily nested; in
|
||||
this case the outer string contains various antiquotations that
|
||||
themselves contain strings (e.g., `"-thread"`), some of which in
|
||||
turn contain expressions (e.g., `${mesa}`).
|
||||
|
||||
The second way to write string literals is as an *indented string*,
|
||||
which is enclosed between pairs of *double single-quotes*, like so:
|
||||
|
||||
```nix
|
||||
''
|
||||
This is the first line.
|
||||
This is the second line.
|
||||
This is the third line.
|
||||
''
|
||||
```
|
||||
|
||||
This kind of string literal intelligently strips indentation from
|
||||
the start of each line. To be precise, it strips from each line a
|
||||
number of spaces equal to the minimal indentation of the string as a
|
||||
whole (disregarding the indentation of empty lines). For instance,
|
||||
the first and second line are indented two spaces, while the third
|
||||
line is indented four spaces. Thus, two spaces are stripped from
|
||||
each line, so the resulting string is
|
||||
|
||||
```nix
|
||||
"This is the first line.\nThis is the second line.\n This is the third line.\n"
|
||||
```
|
||||
|
||||
Note that the whitespace and newline following the opening `''` is
|
||||
ignored if there is no non-whitespace text on the initial line.
|
||||
|
||||
Antiquotation (`${expr}`) is supported in indented strings.
|
||||
|
||||
Since `${` and `''` have special meaning in indented strings, you
|
||||
need a way to quote them. `$` can be escaped by prefixing it with
|
||||
`''` (that is, two single quotes), i.e., `''$`. `''` can be escaped
|
||||
by prefixing it with `'`, i.e., `'''`. `$` removes any special
|
||||
meaning from the following `$`. Linefeed, carriage-return and tab
|
||||
characters can be written as `''\n`, `''\r`, `''\t`, and `''\`
|
||||
escapes any other character.
|
||||
|
||||
Indented strings are primarily useful in that they allow multi-line
|
||||
string literals to follow the indentation of the enclosing Nix
|
||||
expression, and that less escaping is typically necessary for
|
||||
strings representing languages such as shell scripts and
|
||||
configuration files because `''` is much less common than `"`.
|
||||
Example:
|
||||
|
||||
```nix
|
||||
stdenv.mkDerivation {
|
||||
...
|
||||
postInstall =
|
||||
''
|
||||
mkdir $out/bin $out/etc
|
||||
cp foo $out/bin
|
||||
echo "Hello World" > $out/etc/foo.conf
|
||||
${if enableBar then "cp bar $out/bin" else ""}
|
||||
'';
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Finally, as a convenience, *URIs* as defined in appendix B of
|
||||
[RFC 2396](http://www.ietf.org/rfc/rfc2396.txt) can be written *as
|
||||
is*, without quotes. For instance, the string
|
||||
`"http://example.org/foo.tar.bz2"` can also be written as
|
||||
`http://example.org/foo.tar.bz2`.
|
||||
|
||||
- Numbers, which can be *integers* (like `123`) or *floating point*
|
||||
(like `123.43` or `.27e13`).
|
||||
|
||||
Numbers are type-compatible: pure integer operations will always
|
||||
return integers, whereas any operation involving at least one
|
||||
floating point number will have a floating point number as a result.
|
||||
|
||||
- *Paths*, e.g., `/bin/sh` or `./builder.sh`. A path must contain at
|
||||
least one slash to be recognised as such. For instance, `builder.sh`
|
||||
is not a path: it's parsed as an expression that selects the
|
||||
attribute `sh` from the variable `builder`. If the file name is
|
||||
relative, i.e., if it does not begin with a slash, it is made
|
||||
absolute at parse time relative to the directory of the Nix
|
||||
expression that contained it. For instance, if a Nix expression in
|
||||
`/foo/bar/bla.nix` refers to `../xyzzy/fnord.nix`, the absolute path
|
||||
is `/foo/xyzzy/fnord.nix`.
|
||||
|
||||
If the first component of a path is a `~`, it is interpreted as if
|
||||
the rest of the path were relative to the user's home directory.
|
||||
e.g. `~/foo` would be equivalent to `/home/edolstra/foo` for a user
|
||||
whose home directory is `/home/edolstra`.
|
||||
|
||||
Paths can also be specified between angle brackets, e.g.
|
||||
`<nixpkgs>`. This means that the directories listed in the
|
||||
environment variable `NIX_PATH` will be searched for the given file
|
||||
or directory name.
|
||||
|
||||
Antiquotation is supported in any paths except those in angle brackets.
|
||||
`./${foo}-${bar}.nix` is a more convenient way of writing
|
||||
`./. + "/" + foo + "-" + bar + ".nix"` or `./. + "/${foo}-${bar}.nix"`. At
|
||||
least one slash must appear *before* any antiquotations for this to be
|
||||
recognized as a path. `a.${foo}/b.${bar}` is a syntactically valid division
|
||||
operation. `./a.${foo}/b.${bar}` is a path.
|
||||
|
||||
- *Booleans* with values `true` and `false`.
|
||||
|
||||
- The null value, denoted as `null`.
|
||||
|
||||
## Lists
|
||||
|
||||
Lists are formed by enclosing a whitespace-separated list of values
|
||||
between square brackets. For example,
|
||||
|
||||
```nix
|
||||
[ 123 ./foo.nix "abc" (f { x = y; }) ]
|
||||
```
|
||||
|
||||
defines a list of four elements, the last being the result of a call to
|
||||
the function `f`. Note that function calls have to be enclosed in
|
||||
parentheses. If they had been omitted, e.g.,
|
||||
|
||||
```nix
|
||||
[ 123 ./foo.nix "abc" f { x = y; } ]
|
||||
```
|
||||
|
||||
the result would be a list of five elements, the fourth one being a
|
||||
function and the fifth being a set.
|
||||
|
||||
Note that lists are only lazy in values, and they are strict in length.
|
||||
|
||||
## Sets
|
||||
|
||||
Sets are really the core of the language, since ultimately the Nix
|
||||
language is all about creating derivations, which are really just sets
|
||||
of attributes to be passed to build scripts.
|
||||
|
||||
Sets are just a list of name/value pairs (called *attributes*) enclosed
|
||||
in curly brackets, where each value is an arbitrary expression
|
||||
terminated by a semicolon. For example:
|
||||
|
||||
```nix
|
||||
{ x = 123;
|
||||
text = "Hello";
|
||||
y = f { bla = 456; };
|
||||
}
|
||||
```
|
||||
|
||||
This defines a set with attributes named `x`, `text`, `y`. The order of
|
||||
the attributes is irrelevant. An attribute name may only occur once.
|
||||
|
||||
Attributes can be selected from a set using the `.` operator. For
|
||||
instance,
|
||||
|
||||
```nix
|
||||
{ a = "Foo"; b = "Bar"; }.a
|
||||
```
|
||||
|
||||
evaluates to `"Foo"`. It is possible to provide a default value in an
|
||||
attribute selection using the `or` keyword. For example,
|
||||
|
||||
```nix
|
||||
{ a = "Foo"; b = "Bar"; }.c or "Xyzzy"
|
||||
```
|
||||
|
||||
will evaluate to `"Xyzzy"` because there is no `c` attribute in the set.
|
||||
|
||||
You can use arbitrary double-quoted strings as attribute names:
|
||||
|
||||
```nix
|
||||
{ "foo ${bar}" = 123; "nix-1.0" = 456; }."foo ${bar}"
|
||||
```
|
||||
|
||||
This will evaluate to `123` (Assuming `bar` is antiquotable). In the
|
||||
case where an attribute name is just a single antiquotation, the quotes
|
||||
can be dropped:
|
||||
|
||||
```nix
|
||||
{ foo = 123; }.${bar} or 456
|
||||
```
|
||||
|
||||
This will evaluate to `123` if `bar` evaluates to `"foo"` when coerced
|
||||
to a string and `456` otherwise (again assuming `bar` is antiquotable).
|
||||
|
||||
In the special case where an attribute name inside of a set declaration
|
||||
evaluates to `null` (which is normally an error, as `null` is not
|
||||
antiquotable), that attribute is simply not added to the set:
|
||||
|
||||
```nix
|
||||
{ ${if foo then "bar" else null} = true; }
|
||||
```
|
||||
|
||||
This will evaluate to `{}` if `foo` evaluates to `false`.
|
||||
|
||||
A set that has a `__functor` attribute whose value is callable (i.e. is
|
||||
itself a function or a set with a `__functor` attribute whose value is
|
||||
callable) can be applied as if it were a function, with the set itself
|
||||
passed in first , e.g.,
|
||||
|
||||
```nix
|
||||
let add = { __functor = self: x: x + self.x; };
|
||||
inc = add // { x = 1; };
|
||||
in inc 1
|
||||
```
|
||||
|
||||
evaluates to `2`. This can be used to attach metadata to a function
|
||||
without the caller needing to treat it specially, or to implement a form
|
||||
of object-oriented programming, for example.

# Building and Testing
|
||||
|
||||
You can now try to build Hello. Of course, you could do `nix-env -f . -iA
|
||||
hello`, but you may not want to install a possibly broken package just
|
||||
yet. The best way to test the package is by using the command
|
||||
`nix-build`, which builds a Nix expression and creates a symlink named
|
||||
`result` in the current directory:
|
||||
|
||||
```console
|
||||
$ nix-build -A hello
|
||||
building path `/nix/store/632d2b22514d...-hello-2.1.1'
|
||||
hello-2.1.1/
|
||||
hello-2.1.1/intl/
|
||||
hello-2.1.1/intl/ChangeLog
|
||||
...
|
||||
|
||||
$ ls -l result
|
||||
lrwxrwxrwx ... 2006-09-29 10:43 result -> /nix/store/632d2b22514d...-hello-2.1.1
|
||||
|
||||
$ ./result/bin/hello
|
||||
Hello, world!
|
||||
```
|
||||
|
||||
The `-A` option selects the `hello` attribute. This is faster than
|
||||
using the symbolic package name specified by the `name` attribute
|
||||
(which also happens to be `hello`) and is unambiguous (there can be
|
||||
multiple packages with the symbolic name `hello`, but there can be
|
||||
only one attribute in a set named `hello`).
|
||||
|
||||
`nix-build` registers the `./result` symlink as a garbage collection
|
||||
root, so unless and until you delete the `./result` symlink, the output
|
||||
of the build will be safely kept on your system. You can use
|
||||
`nix-build`’s `-o` switch to give the symlink another name.
|
||||
|
||||
Nix has transactional semantics. Once a build finishes successfully, Nix
|
||||
makes a note of this in its database: it registers that the path denoted
|
||||
by `out` is now “valid”. If you try to build the derivation again, Nix
|
||||
will see that the path is already valid and finish immediately. If a
|
||||
build fails, either because it returns a non-zero exit code, because Nix
|
||||
or the builder are killed, or because the machine crashes, then the
|
||||
output paths will not be registered as valid. If you try to build the
|
||||
derivation again, Nix will remove the output paths if they exist (e.g.,
|
||||
because the builder died half-way through `make
|
||||
install`) and try again. Note that there is no “negative caching”: Nix
|
||||
doesn't remember that a build failed, and so a failed build can always
|
||||
be repeated. This is because Nix cannot distinguish between permanent
|
||||
failures (e.g., a compiler error due to a syntax error in the source)
|
||||
and transient failures (e.g., a disk full condition).
|
||||
|
||||
Nix also performs locking. If you run multiple Nix builds
|
||||
simultaneously, and they try to build the same derivation, the first Nix
|
||||
instance that gets there will perform the build, while the others block
|
||||
(or perform other derivations if available) until the build finishes:
|
||||
|
||||
```console
|
||||
$ nix-build -A hello
|
||||
waiting for lock on `/nix/store/0h5b7hp8d4hqfrw8igvx97x1xawrjnac-hello-2.1.1x'

# A Simple Nix Expression
|
||||
|
||||
This section shows how to add and test the [GNU Hello
|
||||
package](http://www.gnu.org/software/hello/hello.html) to the Nix
|
||||
Packages collection. Hello is a program that prints out the text “Hello,
|
||||
world\!”.
|
||||
|
||||
To add a package to the Nix Packages collection, you generally need to
|
||||
do three things:
|
||||
|
||||
1. Write a Nix expression for the package. This is a file that
|
||||
describes all the inputs involved in building the package, such as
|
||||
dependencies, sources, and so on.
|
||||
|
||||
2. Write a *builder*. This is a shell script that builds the package
|
||||
from the inputs. (In fact, it can be written in any language, but
|
||||
typically it's a `bash` shell script.)
|
||||
|
||||
3. Add the package to the file `pkgs/top-level/all-packages.nix`. The
|
||||
Nix expression written in the first step is a *function*; it
|
||||
requires other packages in order to build it. In this step you put
|
||||
it all together, i.e., you call the function with the right
|
||||
arguments to build the actual package.

- [derivation]{#gloss-derivation}\
|
||||
A description of a build action. The result of a derivation is a
|
||||
store object. Derivations are typically specified in Nix expressions
|
||||
using the [`derivation` primitive](expressions/derivations.md). These are
|
||||
using the [`derivation` primitive](language/derivations.md). These are
|
||||
translated into low-level *store derivations* (implicitly by

`nix-env` and `nix-build`, or explicitly by `nix-instantiate`).

- [store]{#gloss-store}\
|
||||
The location in the file system where store objects live. Typically
|
||||
`/nix/store`.
|
||||
|
||||
From the perspective of the location where Nix is
|
||||
invoked, the Nix store can be referred to
|
||||
as a "_local_" or a "_remote_" one:
|
||||
|
||||
+ A *local store* exists on the filesystem of
|
||||
the machine where Nix is invoked. You can use other
|
||||
local stores by passing the `--store` flag to the
|
||||
`nix` command. Local stores can be used for building derivations.
|
||||
|
||||
+ A *remote store* exists anywhere other than the
|
||||
local filesystem. One example is the `/nix/store`
|
||||
directory on another machine, accessed via `ssh` or
|
||||
served by the `nix-serve` Perl script.

|
||||
A local store whose canonical path is anything other than `/nix/store`.
|
||||

||||
- [binary cache]{#gloss-binary-cache}\
|
||||
A *binary cache* is a Nix store which uses a different format: its
|
||||
metadata and signatures are kept in `.narinfo` files rather than in a
|
||||
Nix database. This different format simplifies serving store objects
|
||||
over the network, but cannot host builds. Examples of binary caches

The Nix language is
|
||||
|
||||
- *domain-specific*
|
||||
|
||||
It only exists for the Nix package manager:
|
||||
to describe packages and configurations as well as their variants and compositions.
|
||||
It is not intended for general purpose use.
|
||||
|
||||
- *declarative*
|
||||
|
||||
There is no notion of executing sequential steps.
|
||||
Dependencies between operations are established only through data.
|
||||
|
||||
- *pure*
|
||||
|
||||
Values cannot change during computation.
|
||||
Functions always produce the same output if their input does not change.
|
||||
|
||||
- *functional*
|
||||
|
||||
Functions are like any other value.
|
||||
Functions can be assigned to names, taken as arguments, or returned by functions.
|
||||
|
||||
- *lazy*
|
||||
|
||||
Expressions are only evaluated when their value is needed.
|
||||
|
||||
- *dynamically typed*

Type errors are only detected when expressions are evaluated.

# Data Types
|
||||
|
||||
## Primitives
|
||||
|
||||
- <a id="type-string" href="#type-string">String</a>
|
||||
|
||||
*Strings* can be written in three ways.
|
||||
|
||||
The most common way is to enclose the string between double quotes,
|
||||
e.g., `"foo bar"`. Strings can span multiple lines. The special
|
||||
characters `"` and `\` and the character sequence `${` must be
|
||||
escaped by prefixing them with a backslash (`\`). Newlines, carriage
|
||||
returns and tabs can be written as `\n`, `\r` and `\t`,
|
||||
respectively.
|
||||
|
||||
You can include the result of an expression into a string by
|
||||
enclosing it in `${...}`, a feature known as *antiquotation*. The
|
||||
enclosed expression must evaluate to something that can be coerced
|
||||
into a string (meaning that it must be a string, a path, or a
|
||||
derivation). For instance, rather than writing
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=" + freetype + "/lib"
|
||||
```
|
||||
|
||||
(where `freetype` is a derivation), you can instead write the more
|
||||
natural
|
||||
|
||||
```nix
|
||||
"--with-freetype2-library=${freetype}/lib"
|
||||
```
|
||||
|
||||
The latter is automatically translated to the former. A more
|
||||
complicated example (from the Nix expression for
|
||||
[Qt](http://www.trolltech.com/products/qt)):
|
||||
|
||||
```nix
|
||||
configureFlags = "
|
||||
-system-zlib -system-libpng -system-libjpeg
|
||||
${if openglSupport then "-dlopen-opengl
|
||||
-L${mesa}/lib -I${mesa}/include
|
||||
-L${libXmu}/lib -I${libXmu}/include" else ""}
|
||||
${if threadSupport then "-thread" else "-no-thread"}
|
||||
";
|
||||
```
|
||||
|
||||
Note that Nix expressions and strings can be arbitrarily nested; in
|
||||
this case the outer string contains various antiquotations that
|
||||
themselves contain strings (e.g., `"-thread"`), some of which in
|
||||
turn contain expressions (e.g., `${mesa}`).
|
||||
|
||||
The second way to write string literals is as an *indented string*,
|
||||
which is enclosed between pairs of *double single-quotes*, like so:
|
||||
|
||||
```nix
|
||||
''
|
||||
This is the first line.
|
||||
This is the second line.
|
||||
This is the third line.
|
||||
''
|
||||
```
|
||||
|
||||
This kind of string literal intelligently strips indentation from
|
||||
the start of each line. To be precise, it strips from each line a
|
||||
number of spaces equal to the minimal indentation of the string as a
|
||||
whole (disregarding the indentation of empty lines). For instance,
|
||||
the first and second line are indented two spaces, while the third
|
||||
line is indented four spaces. Thus, two spaces are stripped from
|
||||
each line, so the resulting string is
|
||||
|
||||
```nix
|
||||
"This is the first line.\nThis is the second line.\n This is the third line.\n"
|
||||
```
|
||||
|
||||
Note that the whitespace and newline following the opening `''` is
|
||||
ignored if there is no non-whitespace text on the initial line.
|
||||
|
||||
Antiquotation (`${expr}`) is supported in indented strings.
|
||||
|
||||
Since `${` and `''` have special meaning in indented strings, you
|
||||
need a way to quote them. `$` can be escaped by prefixing it with
|
||||
`''` (that is, two single quotes), i.e., `''$`. `''` can be escaped
|
||||
by prefixing it with `'`, i.e., `'''`. `$` removes any special
|
||||
meaning from the following `$`. Linefeed, carriage-return and tab
|
||||
characters can be written as `''\n`, `''\r`, `''\t`, and `''\`
|
||||
escapes any other character.
|
||||
|
||||
Indented strings are primarily useful in that they allow multi-line
|
||||
string literals to follow the indentation of the enclosing Nix
|
||||
expression, and that less escaping is typically necessary for
|
||||
strings representing languages such as shell scripts and
|
||||
configuration files because `''` is much less common than `"`.
|
||||
Example:
|
||||
|
||||
```nix
|
||||
stdenv.mkDerivation {
|
||||
...
|
||||
postInstall =
|
||||
''
|
||||
mkdir $out/bin $out/etc
|
||||
cp foo $out/bin
|
||||
echo "Hello World" > $out/etc/foo.conf
|
||||
${if enableBar then "cp bar $out/bin" else ""}
|
||||
'';
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Finally, as a convenience, *URIs* as defined in appendix B of
|
||||
[RFC 2396](http://www.ietf.org/rfc/rfc2396.txt) can be written *as
|
||||
is*, without quotes. For instance, the string
|
||||
`"http://example.org/foo.tar.bz2"` can also be written as
|
||||
`http://example.org/foo.tar.bz2`.
|
||||
|
||||
- <a id="type-number" href="#type-number">Number</a>
|
||||
|
||||
Numbers, which can be *integers* (like `123`) or *floating point*
|
||||
(like `123.43` or `.27e13`).
|
||||
|
||||
Numbers are type-compatible: pure integer operations will always
|
||||
return integers, whereas any operation involving at least one
|
||||
floating point number will have a floating point number as a result.
|
||||
|
||||
- <a id="type-path" href="#type-path">Path</a>
|
||||
|
||||
*Paths*, e.g., `/bin/sh` or `./builder.sh`. A path must contain at
|
||||
least one slash to be recognised as such. For instance, `builder.sh`
|
||||
is not a path: it's parsed as an expression that selects the
|
||||
attribute `sh` from the variable `builder`. If the file name is
|
||||
relative, i.e., if it does not begin with a slash, it is made
|
||||
absolute at parse time relative to the directory of the Nix
|
||||
expression that contained it. For instance, if a Nix expression in
|
||||
`/foo/bar/bla.nix` refers to `../xyzzy/fnord.nix`, the absolute path
|
||||
is `/foo/xyzzy/fnord.nix`.
|
||||
|
||||
If the first component of a path is a `~`, it is interpreted as if
|
||||
the rest of the path were relative to the user's home directory.
|
||||
e.g. `~/foo` would be equivalent to `/home/edolstra/foo` for a user
|
||||
whose home directory is `/home/edolstra`.
|
||||
|
||||
Paths can also be specified between angle brackets, e.g.
|
||||
`<nixpkgs>`. This means that the directories listed in the
|
||||
environment variable `NIX_PATH` will be searched for the given file
|
||||
or directory name.
|
||||
|
||||
Antiquotation is supported in any paths except those in angle brackets.
|
||||
`./${foo}-${bar}.nix` is a more convenient way of writing
|
||||
`./. + "/" + foo + "-" + bar + ".nix"` or `./. + "/${foo}-${bar}.nix"`. At
|
||||
least one slash must appear *before* any antiquotations for this to be
|
||||
recognized as a path. `a.${foo}/b.${bar}` is a syntactically valid division
|
||||
operation. `./a.${foo}/b.${bar}` is a path.
|
||||
|
||||
When a path appears in an antiquotation, and is thus coerced into a string,
|
||||
the path is first copied into the Nix store and the resulting string is
|
||||
the Nix store path. For instance `"${./foo.txt}" will cause `foo.txt` in
|
||||
the current directory to be copied into the Nix store and result in the
|
||||
string `"/nix/store/<HASH>-foo.txt"`.
|
||||
|
||||
Note that the Nix language assumes that all input files will remain
|
||||
_unchanged_ during the course of the Nix expression evaluation.
|
||||
If you for example antiquote a file path during a `nix repl` session, and
|
||||
then later in the same session, after having changed the file contents,
|
||||
evaluate the antiquotation with the file path again, then Nix will still
|
||||
return the first store path. It will _not_ reread the file contents to
|
||||
produce a different Nix store path.
|
||||
|
||||
- <a id="type-boolean" href="#type-boolean">Boolean</a>
|
||||
|
||||
*Booleans* with values `true` and `false`.
|
||||
|
||||
- <a id="type-null" href="#type-null">Null</a>
|
||||
|
||||
The null value, denoted as `null`.
|
||||
|
||||
## List
|
||||
|
||||
Lists are formed by enclosing a whitespace-separated list of values
|
||||
between square brackets. For example,
|
||||
|
||||
```nix
|
||||
[ 123 ./foo.nix "abc" (f { x = y; }) ]
|
||||
```
|
||||
|
||||
defines a list of four elements, the last being the result of a call to
|
||||
the function `f`. Note that function calls have to be enclosed in
|
||||
parentheses. If they had been omitted, e.g.,
|
||||
|
||||
```nix
|
||||
[ 123 ./foo.nix "abc" f { x = y; } ]
|
||||
```
|
||||
|
||||
the result would be a list of five elements, the fourth one being a
|
||||
function and the fifth being a set.
|
||||
|
||||
Note that lists are only lazy in values, and they are strict in length.
|
||||
|
||||
## Attribute Set
|
||||
|
||||
An attribute set is a collection of name-value-pairs (called *attributes*) enclosed in curly brackets (`{ }`).
|
||||
|
||||
Names and values are separated by an equal sign (`=`).
|
||||
Each value is an arbitrary expression terminated by a semicolon (`;`).
|
||||
|
||||
Attributes can appear in any order.
|
||||
An attribute name may only occur once.
|
||||
|
||||
Example:
|
||||
|
||||
```nix
|
||||
{
|
||||
x = 123;
|
||||
text = "Hello";
|
||||
y = f { bla = 456; };
|
||||
}
|
||||
```
|
||||
|
||||
This defines a set with attributes named `x`, `text`, `y`.
|
||||
|
||||
Attributes can be selected from a set using the `.` operator. For
|
||||
instance,
|
||||
|
||||
```nix
|
||||
{ a = "Foo"; b = "Bar"; }.a
|
||||
```
|
||||
|
||||
evaluates to `"Foo"`. It is possible to provide a default value in an
|
||||
attribute selection using the `or` keyword. For example,
|
||||
|
||||
```nix
|
||||
{ a = "Foo"; b = "Bar"; }.c or "Xyzzy"
|
||||
```
|
||||
|
||||
will evaluate to `"Xyzzy"` because there is no `c` attribute in the set.
|
||||
|
||||
You can use arbitrary double-quoted strings as attribute names:
|
||||
|
||||
```nix
|
||||
{ "foo ${bar}" = 123; "nix-1.0" = 456; }."foo ${bar}"
|
||||
```
|
||||
|
||||
This will evaluate to `123` (Assuming `bar` is antiquotable). In the
|
||||
case where an attribute name is just a single antiquotation, the quotes
|
||||
can be dropped:
|
||||
|
||||
```nix
|
||||
{ foo = 123; }.${bar} or 456
|
||||
```
|
||||
|
||||
This will evaluate to `123` if `bar` evaluates to `"foo"` when coerced
|
||||
to a string and `456` otherwise (again assuming `bar` is antiquotable).
|
||||
|
||||
In the special case where an attribute name inside of a set declaration
|
||||
evaluates to `null` (which is normally an error, as `null` is not
|
||||
antiquotable), that attribute is simply not added to the set:
|
||||
|
||||
```nix
|
||||
{ ${if foo then "bar" else null} = true; }
|
||||
```
|
||||
|
||||
This will evaluate to `{}` if `foo` evaluates to `false`.
|
||||
|
||||
A set that has a `__functor` attribute whose value is callable (i.e. is
|
||||
itself a function or a set with a `__functor` attribute whose value is
|
||||
callable) can be applied as if it were a function, with the set itself
|
||||
passed in first , e.g.,
|
||||
|
||||
```nix
|
||||
let add = { __functor = self: x: x + self.x; };
|
||||
inc = add // { x = 1; };
|
||||
in inc 1
|
||||
```
|
||||
|
||||
evaluates to `2`. This can be used to attach metadata to a function
|
||||
without the caller needing to treat it specially, or to implement a form
|
||||
of object-oriented programming, for example.

how to obtain, install, upgrade, and erase packages. This is the

“user’s” perspective of the Nix system — people who want to *create*

packages should consult the [chapter on writing Nix

* Allow explicitly selecting outputs with *store derivations* installable syntax too.

* `<nix/fetchurl.nix>` now accepts an additional argument `impure` which

defaults to `false`. If it is set to `true`, the `hash` and `sha256`

arguments will be ignored and the resulting derivation will have
