[doc]: How to manually retrigger f-s-h from within a user's ZLE widget function?

Problem

If there is a simple way to achieve this, it would be great to include that in the README.

The use case I have here is a custom zle widget that puts a filepath on the line being edited.

Afterward, I need to move the cursor before f-s-h will rescan the line (and colorize an existing filepath).

I thought maybe I could check for a certain f-s-h zle function and run it at the end of my zle function.

Suggested improvement

To manually trigger a rescan of the current line from your own ZLE widgets, use

if (( $+functions[fast-highlight-rescan] )) fast-highlight-rescan

I thought this might work, but it doesn't:

for 1 ( preexec $preexec_functions ) {
  if (( $+functions[$1] ))  $1 &>/dev/null
}
zle -R

Oh looks like maybe f-s-h rewrites all defined ZLE widgets when loaded, so I'll need to rearrange things to define my widget before that.

EDIT: still no luck

Ah, this seems to do the trick, dropped at the end of any custom ZLE widgets:

if (( $+functions[_zsh_highlight] ))  _zsh_highlight
