# gst-build
GStreamer [meson](http://mesonbuild.com/) based repositories aggregrator
You can build GStreamer and all its modules at once using
meson and its [subproject](https://github.com/mesonbuild/meson/wiki/Subprojects) feature.
## Getting started
### Install meson and ninja
You should get meson through your package manager or using:
$ pip3 install --user meson
You should get `ninja` using your package manager or downloading it from
[here](https://github.com/ninja-build/ninja/releases).
### Build GStreamer and its modules
You can get all GStreamer built running:
```
mkdir build/ && meson build && ninja -C build/
```
NOTE: on fedora (and maybe other distributions) replace `ninja` with `ninja-build`
# Development environment
gst-build also contains a special `uninstalled` target that lets you enter an
uninstalled development environment where you will be able to work on GStreamer easily.
You can get into that environment running:
```
ninja -C build/ uninstalled
```
If your operating system handles symlinks, built modules source code will be available
at the root of `gst-build/` for example GStreamer core will be in `gstreamer/`. Otherwise
they will be present in `subprojects/`. You can simply hack in there and to rebuild you
just need to rerun `ninja -C build/`.
## Add information about GStreamer development environment in your prompt line
### Bash prompt
We automatically handle `bash` and set `$PS1` accordingly
### Zsh prompt
In your `.zshrc`, you should add something like:
```
export PROMPT="$GST_ENV-$PROMPT"
```
### Using powerline
In your powerline theme configuration file (by default in
`{POWERLINE INSTALLATION DIR}/config_files/themes/shell/default.json`)
you should add a new environment segment as follow:
```
{
"function": "powerline.segments.common.env.environment",
"args": { "variable": "GST_ENV" },
"priority": 50
},
```
