The [Kate lsp branch](https://cgit.kde.org/kate.git/log/?h=lsp) contains now the infrastructure as used by Qt Creator.
|
||
|
|
In addition, [clangd](https://clang.llvm.org/extra/clangd/) is now somehow started in a working state for the first project opened inside Kate.
|
||
|
|
|
||
|
|
For example, if you use the CMake Kate project generator and you compile Kate from the "lsp" branch, clangd should pick up the compile_commands.json for a CMake generated Kate project.
|
||
|
|
|
||
|
|
;=) Unfortunately not much more than starting and informing clangd about the open workspaces (for the first opened project) works ATM.

If you press ALT-1 over some identifier, you will get some debug output on the console about found links, like below:
|
||
|
|
|
||
|
|
{{< highlight bash >}}
|
||
|
|
qtc.languageclient.parse: content: "{\"id\":\"{812e04c6-2bca-42e3-a632-d616fdc2f7d4}\",\"jsonrpc\":\"2.0\",\"result\":[{\"range\":{\"end\":{\"character\":20,\"line\":67},\"start\":{\"character\":6,\"line\":67}},\"uri\":\"file:///local/cullmann/kde/src/kate/kate/katemainwindow.h\"}]}"
|
||
|
|
{{< / highlight >}}
|
||
|
|
|
||
|
|
The current ALT-1 handling is a big hack, as then one just adds the current document and triggers the GotoDefinitionRequest.
|
||
|
|
A proper implementation tracks the opened/closed documented of the editor.
|
||
|
|
|
||
|
|
But at least in principle Kate is now able to start some language server processes and talk a bit with them, all thanks to the nice code borrowed from Qt Creator.
|

:=) As my spare time is limited, any help in bringing the branch up-to-speed is highly welcome, just drop us a mail to [kwrite-devel@kde.org](mailto:kwrite-devel@kde.org) or mail me in private ([cullmann@kde.org](mailto:cullmann@kde.org)).

A working LSP integration will help to make Kate more attractive for programmers of many languages.
