After my series of LSP client posts, I got the question: What does this actually do? And why should I like this or help with it?
For the basic question: What the heck is the Language Server Protocol (LSP), I think my first post can help. Or, for more details, just head over to the official what/why/… page.
But easier than to describe why it is nice, I can just show the stuff in action. Below is a video that shows the features that at the moment work with our master branch. It is shown using the build directory of Kate itself.
To get a usable build directory, I build my stuff locally with kdesrc-build, the only extra config I have in the global section of my .kdesrc-buildrc is:
cmake-options -DCMAKE_BUILD_TYPE=RelWithDebInfo -G “Kate - Unix Makefiles” -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
This will auto generate the needed .kateproject files for the Kate project plugin and the compile_commands.json for clangd (the LSP server for C/C++ the plugin uses).
If you manually build your stuff with cmake, you can just add the
-G “Kate - Unix Makefiles” -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
parts to your cmake call. If you use ninja and not make, just use
-G “Kate - Ninja” -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
Then, let’s see what you can do, once you are in a prepared build directory and have a master version of Kate in your PATH.
I hope the quality is acceptable, that is my first try in a long time to do some screen-cast ;)
As you can see, this is already in an usable state at least for C/C++ in combination with clangd.
For details how to build Kate master with it’s plugins, please take a look at this guide.
If you want to start to hack on the plugin, you find it in the kate.git, addons/lspclient.
Feel welcome to show up on kwrite-devel@kde.org and help out! All development discussions regarding this plugin happen there.
If you are already familiar with Phabricator, post some patch directly at KDE’s Phabricator instance.
