I’ve setup kak-lsp like so
plug "ul/kak-lsp" do %{
cargo build --release --locked
cargo install --force --path . --locked
cargo clean
} config %{
set-option global lsp_cmd "kak-lsp --kakoune -vvv -c $HOME/.config/kak-lsp/kak-lsp.toml -s %val{session} --log $HOME/.config/kak-lsp/kak-lsp.log"
define-command lsp-restart %{ lsp-stop; lsp-start }
set-option global lsp_completion_trigger "execute-keys 'h<a-h><a-k>\S[^\s,=;*(){}\[\]]\z<ret>'"
set-option global lsp_diagnostic_line_error_sign "!"
set-option global lsp_diagnostic_line_warning_sign "?"
hook global WinSetOption filetype=(c|cpp|objc|d|rust|haskell|nim|elixir|latex|javascript) %{
lsp-start
# ^ I'm apparently need to use this and not an `eval %sh{}`, because it will gripe in *debug*
# that "command lsp-start already exists" or something like that.
lsp-enable-window
echo -debug "Enabling LSP for filtetype %opt{filetype}"
lsp-auto-hover-enable
lsp-auto-hover-insert-mode-disable
set-option global lsp_auto_highlight_references true
set-option global lsp_hover_anchor true
# Semantic highlighting
hook window -group semantic-tokens BufReload .* lsp-semantic-tokens
hook window -group semantic-tokens NormalIdle .* lsp-semantic-tokens
hook window -group semantic-tokens InsertIdle .* lsp-semantic-tokens
hook -once -always window WinSetOption filetype=.* %{
remove-hooks window semantic-tokens
}
# Other things
#hook window BufWritePre .* lsp-formatting-sync # this breaks shit
hook window BufWritePost .* lsp-diagnostics
hook -always global KakEnd .* lsp-exit
hook global WinSetOption filetype=rust %{
set-option window lsp_server_configuration rust.clippy_preference="on"
}
}
}
And my kak-lsp.toml

But when I open up a Typescript project, I’ve yet to see anything that indicates kak-lsp has started. I can’t find it as a running process, nor can I find tsserver running. There’s no hovering, or any completion outside of what is in the buffer. This is the same with other language servers.
What exactly am I missing?
EDIT: ~/.cargo/bin is in my path for the shell I use (fish-shell), but does it need to be in the path for plain sh as well?
Ah, I see this issue is that I have to actually have the kak-lsp command ran with eval %sh{}, and that in the kak-lsp.toml I have to have the field filetypes not fileTYPE. I’ve fixed them in this post as well.
