Approach for binary command completion to show TLDR Pages (or man pages)

[jeeftor]

I'm trying to understand the best way to go about this and/or if there is a function that can already handle it.

I'm using zsh and thought Wouldn't it be cool if I typed a command the preview showed TLDR pages for it

Is there a function I can call for doing "command" completion?

I was messing with stuff and it didn't seem to pass the command I'm trying to complete into my preview function...

echo "ARGS [$@]"

I'm sure I'm missing something somewhere

# Disable menu completions for everything
zstyle ':completion:*' menu no

# Set Custom fzf Preview for All Completions - using fzf-preview
zstyle ':fzf-tab:complete:*' fzf-preview '$HOME/bin/fzf-preview.sh $realpath'
zstyle ':fzf-tab:complete:*' fzf-bindings 'ctrl-/:toggle-preview'

# Set Custom fzf Preview for cd Command
zstyle ':fzf-tab:complete:cd:*' fzf-preview 'lsd --tree --color=always  --git $realpath | head -200'

# Disable fzf Preview for git
zstyle ':fzf-tab:complete:git:*' fzf-preview ''

# Configure Keys to Switch Completion Groups in fzf
zstyle ':fzf-tab:*' switch-group '<' '>'

echo "ARGS [$@]"

If you would like to reference some value you could use placeholders or some environment variables exported by fzf.

Placeholder

Placeholder	Description
{}	current line
{2}	current line with positional field 2
{2..}	current line from the 2nd field to the last field
{n}	current line number (zero index)
{q}	current query

Placeholder expression flags	Description
+	space-separated list of the selected lines
f	temporary file
s	preserve whitespace

Environment Variables

You can skim the fzf man page or view them in the preview window.

man fzf | less --pattern "ENVIRONMENT VARIABLES EXPORTED TO CHILD PROCESSES"

: | fzf --preview "typeset | grep '^FZF_'"

The wiki has some examples, e.g.:

• junegunn/fzf Wiki · fzf-man-pages widget (for zsh)

I found the desc env var had what I wanted. Which is odd
