v-pkgconfig
|
|
===========
|
|
|
|
This module implements the `pkg-config` tool as a library in pure V.
|
|
|
|
Features:
|
|
|
|
* Simple API, but still not stable, but shouldnt change much
|
|
* Runs 2x faster than original pkg-config
|
|
* Commandline tool that aims to be compatible with `pkg-config`
|
|
* Resolve full path for `.pc` file given a name
|
|
* Recursively parse all the dependencies
|
|
* Find and replace all inner variables
|
|
|
|
Todo/Future/Wish:
|
|
|
|
* 100% compatibility with `pkg-config` options
|
|
* Integration with V, to support pkgconfig with `system()`
|
|
* Strictier pc parsing logic, with better error reporting
|
|
|
|
Example

$ ./bin/pkgconfig -h
|
|
pkgconfig 0.2.0

|
|
|
|
```
|
|
>>> import pkgconfig

|
|
>>> mut pc := pkgconfig.load('r_core', opt) or { panic(err) }
|
|
>>> pc.libs
