# gir2pas
The [gir2pas][] utility is a program to convert the
GIR metadata format (= XML files) used by [GObject introspection][] into usable
Pascal source code, suitable for generating corresponding language bindings.
It was originaly named [gir2pascal] maintained as part of the Lazarus Code and Component Repository ([lazarus-ccr][],
[wiki article][wiki-ccr]), see `applications/gobject-introspection/`. Later it has
received some maintenance by [n1tehawk][] and finally was imported from his
repository into Lazarus source tree.
# License
This project builds upon the original Lazarus CCR version and is thus intended
to follow the same licensing principles. For the `gobject-introspection` folder
this seems to be [GPL v2](LICENSE.md), as referenced in a number of file headers.
# Usage
## Compilation
In order to compile `gir2pas` one needs to install FPC and make:
```
aptitude install fpc make
```
Then run default make target:
```
make
```
## Generation of bindings
First, the GIR files need to be installed:
```
aptitude install \
libatk1.0-dev \
libgtk-3-dev \
libgdk-pixbuf-2.0-dev \
gir1.2-glib-2.0-dev \
libgirepository1.0-dev \
libgtk-3-dev \
libharfbuzz-dev \
libpango1.0-dev \
gir1.2-freedesktop-dev
```
Then run the program:
```
./gir2pas -P Laz -e Set -w \
-M atk-2.52 \
-M cairo-1.0 \
-M gdk-3.22 \
-M glib-2.66 \
-M gio-2.66 \
-M gmodule-2.66 \
-M gobject-2.66 \
-M gtk-3.24 \
-M pango-1.16 \
-M pangocairo-1.46 \
-i Gtk-3.0 \
-o ../lazarus/lcl/interfaces/gtk3/gtk3bindings/
