Add option to jump to file from :peek

[mahulst]

I added a bunch of things to my local kak files for this plugin. It's similar to how cargo.kak jumps to files from cargo errors.
I add the line set-option buffer filetype harpoon to set the file type in the :peek command.

# Add and remove hooks to pressing enter
hook global WinSetOption filetype=harpoon %{
    map -docstring "Jump to position" buffer normal <ret> %{: harpoon-jump<ret>}
}
hook global WinSetOption filetype=(?!harpoon).* %{
    unmap buffer normal <ret> %{: harpoon-jump<ret>}
}

declare-option -docstring "regex describing file paths and line numbers" \
    regex \
    harpoon_file_pattern \
    "/(\w|\.|/)+:\d+:\d+"

# jump to file where the cursor is
define-command harpoon-jump %{

    evaluate-commands -save-regs fl %{

        execute-keys -draft "g" "h" "/" %opt{harpoon_file_pattern} <ret> "<a-;>" ";T:" '"fy' 'llT:"ly'

	harpoon-line-column %reg{f} %reg{l}
    }
}
# helper
define-command harpoon-line-column -params 2 %{
    evaluate-commands -try-client %opt{jumpclient} %{
        edit -existing "%arg{1}" "%arg{2}" 

        try %{ focus }
    }
} -docstring "Like edit but understands file:line:col parameters"
