buildGo.nix
|
|
||||||
===========
|
|
||||||
|
|
||||||
This is an alternative [Nix][] build system for [Go][]. It supports building Go
|
|
||||||
libraries and programs.
|
|
||||||
|
|
||||||
*Note:* This will probably end up being folded into [Nixery][].
|
|
||||||
|
|
||||||
## Background
|
|
||||||
|
|
||||||
Most language-specific Nix tooling outsources the build to existing
|
|
||||||
language-specific build tooling, which essentially means that Nix ends up being
|
|
||||||
a wrapper around all sorts of external build systems.
|
|
||||||
|
|
||||||
However, systems like [Bazel][] take an alternative approach in which the
|
|
||||||
compiler is invoked directly and the composition of programs and libraries stays
|
|
||||||
within a single homogeneous build system.
|
|
||||||
|
|
||||||
Users don't need to learn per-language build systems and especially for
|
|
||||||
companies with large monorepo-setups ([like Google][]) this has huge
|
|
||||||
productivity impact.
|
|
||||||
|
|
||||||
This project is an attempt to prove that Nix can be used in a similar style to
|
|
||||||
build software directly, rather than shelling out to other build systems.
|
|
||||||
|
|
||||||
## Example
|
|
||||||
|
|
||||||
Given a program layout like this:
|
|
||||||
|
|
||||||
```
|
|
||||||
.
|
|
||||||
├── lib <-- some library component
|
|
||||||
│ ├── bar.go
|
|
||||||
│ └── foo.go
|
|
||||||
├── main.go <-- program implementation
|
|
||||||
└── default.nix <-- build instructions
|
|
||||||
```
|
|
||||||
|
|
||||||
The contents of `default.nix` could look like this:
|
|
||||||
|
|
||||||
```nix
|
|
||||||
{ buildGo }:
|
|
||||||
|
|
||||||
let
|
|
||||||
lib = buildGo.package {
|
|
||||||
name = "somelib";
|
|
||||||
srcs = [
|
|
||||||
./lib/bar.go
|
|
||||||
./lib/foo.go
|
|
||||||
];
|
|
||||||
};
|
|
||||||
in buildGo.program {
|
|
||||||
name = "my-program";
|
|
||||||
deps = [ lib ];
|
|
||||||
|
|
||||||
srcs = [
|
|
||||||
./main.go
|
|
||||||
];
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
(If you don't know how to read Nix, check out [nix-1p][])
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
`buildGo` exposes five different functions:
|
|
||||||
|
|
||||||
* `buildGo.program`: Build a Go binary out of the specified source files.
|
|
||||||
|
|
||||||
| parameter | type | use | required? |
|
|
||||||
|-----------|-------------------------|------------------------------------------------|-----------|
|
|
||||||
| `name` | `string` | Name of the program (and resulting executable) | yes |
|
|
||||||
| `srcs` | `list<path>` | List of paths to source files | yes |
|
|
||||||
| `deps` | `list<drv>` | List of dependencies (i.e. other Go libraries) | no |
|
|
||||||
| `x_defs` | `attrs<string, string>` | Attribute set of linker vars (i.e. `-X`-flags) | no |
|
|
||||||
|
|
||||||
* `buildGo.package`: Build a Go library out of the specified source files.
|
|
||||||
|
|
||||||
| parameter | type | use | required? |
|
|
||||||
|-----------|--------------|------------------------------------------------|-----------|
|
|
||||||
| `name` | `string` | Name of the library | yes |
|
|
||||||
| `srcs` | `list<path>` | List of paths to source files | yes |
|
|
||||||
| `deps` | `list<drv>` | List of dependencies (i.e. other Go libraries) | no |
|
|
||||||
| `path` | `string` | Go import path for the resulting library | no |
|
|
||||||
|
|
||||||
* `buildGo.external`: Build an externally defined Go library or program.
|
|
||||||
|
|
||||||
This function performs analysis on the supplied source code (which
|
|
||||||
can use the standard Go tooling layout) and creates a tree of all
|
|
||||||
the packages contained within.
|
|
||||||
|
|
||||||
This exists for compatibility with external libraries that were not
|
|
||||||
defined using buildGo.
|
|
||||||
|
|
||||||
| parameter | type | use | required? |
|
|
||||||
|-----------|----------------|-----------------------------------------------|-----------|
|
|
||||||
| `path` | `string` | Go import path for the resulting package | yes |
|
|
||||||
| `src` | `path` | Path to the source **directory** | yes |
|
|
||||||
| `deps` | `list<drv>` | List of dependencies (i.e. other Go packages) | no |
|
|
||||||
|
|
||||||
## Current status
|
|
||||||
|
|
||||||
This project is work-in-progress. Crucially it is lacking the following features:
|
|
||||||
|
|
||||||
* feature flag parity with Bazel's Go rules
|
|
||||||
* documentation building
|
|
||||||
* test execution
|
|
||||||
|
|
||||||
There are still some open questions around how to structure some of those
|
|
||||||
features in Nix.
