Building and Installing Valencia
To build Valencia, you'll need to have the following programs and libraries installed:
valac, the Vala compiler. Valencia depends on the valac libraries for system vapi directory information. If valac is not installed, Valencia may not function correctly! Valencia 0.4 requires Vala 0.17.1 to 0.18.1. The current build of Valencia in git master requires 0.20.1.
On Ubuntu (and perhaps Debian), you can install the required build dependencies like this:
$ sudo apt-get install valac libvala-dev gedit-dev libgee-dev libvte-2.90-dev m4
(You may have to specify which version of valac and libvala-dev you wish to install. For Valencia 0.4, choose Vala 0.18.)
You can download the latest source release or check out the latest code (possibly unstable) using git:
$ git clone git://git.gnome.org/valencia
Then run make and make install. (Do not run sudo make install. Valencia installs in your ~/.gnome2/gedit directory, and if you install as root the permissions will be wrong.)
To enable Valencia in gedit, go to Edit -> Preferences -> Plugins and check the Valencia checkbox.
NOTE for gedit 3.8 users: Valencia 0.4 does not work with gedit 3.7.5 and above. The fix introduces bugs into earlier versions of gedit (see #6852). gedit 3.8 support is currently maintained in git master and will be available in Valencia 0.5.
