- derivation\
|
||||
- [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
|
||||
translated into low-level *store derivations* (implicitly by
|
||||
`nix-env` and `nix-build`, or explicitly by `nix-instantiate`).
|
||||
|
||||
- store\
|
||||
- [store]{#gloss-store}\
|

The location in the file system where store objects live. Typically

`/nix/store`.

- store path\

The location in the file system of a store object, i.e., an

immediate child of the Nix store directory.

|

- store object\
|
||||
- [store object]{#gloss-store-object}\
|
||||
A file that is an immediate child of the Nix store directory. These
|
||||
can be regular files, but also entire directory trees. Store objects
|
||||
can be sources (objects copied from outside of the store),
|
||||
derivation outputs (objects produced by running a build action), or
|
||||
derivations (files describing a build action).
|
||||
|
||||
- substitute\
|
||||
- [substitute]{#gloss-substitute}\
|
||||
A substitute is a command invocation stored in the Nix database that
|
||||
describes how to build a store object, bypassing the normal build
|
||||
mechanism (i.e., derivations). Typically, the substitute builds the
|
||||
store object by downloading a pre-built version of the store object
|
||||
from some server.
|
||||
|
||||
- purity\
|
||||
- [purity]{#gloss-purity}\
|
||||
The assumption that equal Nix derivations when run always produce
|
||||
the same output. This cannot be guaranteed in general (e.g., a
|
||||
builder can rely on external inputs such as the network or the
|
||||
system time) but the Nix model assumes it.
|
||||
|
||||
- Nix expression\
|
||||
- [Nix expression]{#gloss-nix-expression}\
|
||||
A high-level description of software packages and compositions
|
||||
thereof. Deploying software using Nix entails writing Nix
|
||||
expressions for your packages. Nix expressions are translated to
|
||||
derivations that are stored in the Nix store. These derivations can

then be built.

* Running Nix with the new `--debugger` flag will cause it to start a
|
||||
repl session if an exception is thrown during evaluation, or if
|
||||
`builtins.break` is called. From there you can inspect the values
|
||||
of variables and evaluate Nix expressions. In debug mode, the
|
||||
following new repl commands are available:
|
||||
|
||||
```
|

:env Show env stack
|
||||
:bt Show trace stack
|
||||
:st Show current trace
|

:st <idx> Change to another trace in the stack

:c Go until end of program, exception, or builtins.break().

feature. It is now included in the Nix installation in the form of

an autoloadable shell function, `run-help-nix`. It picks up Nix

subcommands from the currently typed in command and directs the user

or read even with restricted evaluation. Note that this will not

|

`nix-build`.

e.g. `nixpkgs#glibc^dev,static` or `nixpkgs#glibc^*`. By default,
