How to install and patch st
Click the download link on the st website at the very bottom and extract (replace the version number):
cd $HOME/Downloads/
tar xvf st-X.X.tar.gz
Now, you can build and have a working binary of st (although, very minimal):
cd st-X.X/
make clean install
Check out the available patches here. Take the one you need and download with:
curl -O <download link>
Apply the patch:
patch -p1 < path/to/patch.diff
And rebuild the binary:
make clean install
Voilà! The patch should be applied.
