Eelco Dolstra e81d38c02b nix-shell: Execute shellHook if it exists
Since normal builds don't execute shellHook, this allows nix-shell
specific customisation.  Suggested by Domen.

Eelco Dolstra b632153ebd nix-shell: Use shell.nix as the default expression if it exists 2014-02-10 10:25:13 +01:00
Eelco Dolstra c5ba081333 nix-shell: Add --impure flag
This is currently the default, but I might change that to --pure in
the future.

Eelco Dolstra f1357059a4 nix-shell: Don't set NIX_INDENT_MAKE
It generally is not useful in interactive environments (and messes up
some non-ANSI-compliant terminals).

This has some hacky applications.

Eelco Dolstra 4f4a14453a Don't set $PS1 in non-interactive shells
Shouldn't really matter, but you never know.

Shea Levy 4ea034a5c5 nix-shell: Play nicely with non-interactive shells
nix-shell with the --command flag might be used non-interactively, but
if bash starts non-interactively (i.e. with stdin or stderr not a
terminal), it won't source the script given in --rcfile. However, in
that case it *will* source the script found in $BASH_ENV, so we can use
that instead.

Also, don't source ~/.bashrc in a non-interactive shell (detectable by
checking the PS1 env var)

Eelco Dolstra c1994fecf9 nix-shell: Fix bash completion
Nixpkgs's stdenv setup script sets the "nullglob" option, but doing so
breaks Bash completion on NixOS (when ‘programs.bash.enableCompletion’
is set) and on Ubuntu.  So clear that flag afterwards.  Of course,
this may break stdenv functions in subtle ways...

Eelco Dolstra 511455965e nix-shell: Don't disable Automake dependency tracking
Nixpkgs' stdenv disables dependency tracking by default.  That makes
sense for one-time builds, but in an interactive environment we expect
repeated "make" invocations to do the right thing.

Eelco Dolstra 15e5ac8039 nix-shell: Set $IN_NIX_SHELL
This allows scripts to distinguish between a real build and a Nix
shell.

Eelco Dolstra 48858ad5ca nix-shell: Set some environment variables also set by build.cc
Setting $NIX_STORE causes the purity checks in gcc/ld-wrapper to kick
in, so that's why we unset $NIX_ENFORCE_PURITY.

Eelco Dolstra 2bc5de8635 Rename ‘nix-build --run-env’ to ‘nix-shell’ 2013-07-19 12:02:44 +02:00
Eelco Dolstra dc5f2e7da6 nix-build --run-env: Add a ‘--pure’ flag
This causes the environment to be (almost) cleared, thus giving a
shell that more closely resembled the actual Nix derivation.

Eelco Dolstra 656390062a nix-build --run-env: Source $stdenv/setup in the interactive shell
This ensures that not just environment variables are set, but also
shell functions such as unpackPhase, configurePhase and so on.

Eelco Dolstra 08964d7328 Undo accidental debug change 2012-11-26 17:57:14 +01:00
Eelco Dolstra 46a369ad95 Make "nix-build -A <derivation>.<output>" do the right thing
For example, given a derivation with outputs "out", "man" and "bin":

  $ nix-build -A pkg

produces ./result pointing to the "out" output;

  $ nix-build -A pkg.man

produces ./result-man pointing to the "man" output;

  $ nix-build -A pkg.all

produces ./result, ./result-man and ./result-bin;

  $ nix-build -A pkg.all -A pkg2

produces ./result, ./result-man, ./result-bin and ./result-2.

Eelco Dolstra a562d544d8 When ‘--help’ is given, just run ‘man’ to show the manual page
I.e. do what git does.  I'm too lazy to keep the builtin help text up
to date :-)

Also add ‘--help’ to various commands that lacked it
(e.g. nix-collect-garbage).

Eelco Dolstra a9e6752bbd Include the output name in the GC root link
Output names are now appended to resulting GC symlinks, e.g. by
nix-build.  For backwards compatibility, if the output is named "out",
nothing is appended.  E.g. doing "nix-build -A foo" on a derivation
that produces outputs "out", "bin" and "dev" will produce symlinks
"./result", "./result-bin" and "./result-dev", respectively.

Eelco Dolstra b8fb0ce563 Update "nix-build --help" 2012-03-27 11:59:36 +02:00
Eelco Dolstra 5144abe5b6 Add an option "--exclude" to filter dependencies in "nix-build --run-env"
Sometimes when doing "nix-build --run-env" you don't want all
dependencies to be built.  For instance, if we want to do "--run-env"
on the "build" attribute in Hydra's release.nix (to get Hydra's build
environment), we don't want its "tarball" dependency to be built.  So
we can do:

  $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

This will skip the dependency whose name matches the "hydra-tarball"
regular expression.  The "--exclude" option can be repeated any number
of times.

Eelco Dolstra 3e94ffffd6 Allow the command executed by "nix-build --run-env" to be overriden with --command 2012-03-27 11:16:43 +02:00
Eelco Dolstra 7f38087f35 Add a command "nix-build --run-env" to reproduce the environment of a derivation
This command builds or fetches all dependencies of the given
derivation, then starts a shell with the environment variables from
the derivation.  This shell also sources $stdenv/setup to initialise
the environment further.

The current directory is not changed.  Thus this is a convenient way
to reproduce a build environment in an existing working tree.

Existing environment variables are left untouched (unless the
derivation overrides them).  As a special hack, the original value of
$PATH is appended to the $PATH produced by $stdenv/setup.

Example session:

$ nix-build --run-env '<nixpkgs>' -A xterm
(the dependencies of xterm are built/fetched...)
$ tar xf $src
$ ./configure
$ make
$ emacs
(... hack source ...)
$ make
$ ./xterm

Eelco Dolstra 2a3f4110c5 * nix-build: put the temporary derivation symlink in a temporary
directory rather than the current directory.
* nix-build: --drv-link now implies --add-drv-link.

Eelco Dolstra a7366a764a * Add a -I flag to the Perl bindings to nix-build and some other
scripts.
* Include the version and architecture in the -I flag so that there is
  at least a chance that a Nix binary built for one Perl version will
  run on another version.

Eelco Dolstra 5090c34ee1 * Set the executable bit on scripts. 2011-10-10 22:40:17 +00:00
Eelco Dolstra 1ecc97b6bd * Add a Nix expression search path feature. Paths between angle
brackets, e.g.

    import <nixpkgs/pkgs/lib>

  are resolved by looking them up relative to the elements listed in
  the search path.  This allows us to get rid of hacks like

    import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

  The search path can be specified through the ‘-I’ command-line flag
  and through the colon-separated ‘NIX_PATH’ environment variable,
  e.g.,

    $ nix-build -I /etc/nixos ...

  If a file is not found in the search path, an error message is
  lazily thrown.

Eelco Dolstra 80e722278c * When using the build hook, distinguish between the stderr of the
hook script proper, and the stdout/stderr of the builder.  Only the
  latter should be saved in /nix/var/log/nix/drvs.
* Allow the verbosity to be set through an option.
* Added a flag --quiet to lower the verbosity level.

Eelco Dolstra 20b6f94b65 * nix-build: pass the --show-trace flag. 2009-07-15 09:10:38 +00:00
Eelco Dolstra f24cf5d303 * nix-build: if nix-instantiate or nix-store fails due to a signal
(e.g. out of memory or a segfault), print an error message.
  Otherwise the user doesn't see anything.
2009-06-10 11:30:34 +00:00
Eelco Dolstra 1dcf208f56 * Clean up some tests (use nix-build where appropriate). 2009-03-18 13:15:55 +00:00
