kak-lsp-diags 1.1.0

Kakoune plugin for LSP hover diagnostics

Kakoune LSP Diagnostics Hover

This plugin integrates with kakoune-lsp to provide better hover support for inline diagnostics. It has a single function: to show inlay diagnostics only when the cursor is on an inline diagnostic.

In other words, if the cursor is over an error (the part underlined in red), the diagnostic's text will be displayed at the end of the line. As soon as the cursor is moved, the text clears.

Installation

kak-lsp-diags is available as a package on PyPI. You can install it with your favorite python package manager:

uv tool install kak-lsp-diags

Usage

Invoking the kak-lsp-diags command outputs necessary Kakoune commands and starts a daemon. To use the plugin, add the following to your kakrc:

evaluate-commands %sh{ kak-lsp-diags }

Then, you can use the lsp-diag-hover-enable and lsp-diag-hover-disable commands to control the plugin.

If you wish, you can see the contents of static.kak (the injected commands) without starting the server:

kak-lsp-diags --print-static

Advanced Usage

Some users may want to customize what happens when the cursor hovers & leaves a diagnostic. In this case, you'll need to replace the commands injected by the plugin. To reference what's currently executed, use the --print-static flag, or see static.kak in this repository. Feel free to write your own version and add it to your kakrc.

Invoking the command with the --no-static option will not print static.kak for evaluation by Kakoune. However, note that the diagpipe_in and diagpipe_out options are always declared.
