URLPattern Regex Capture Groups

[arnold-c]

I'm trying to write a search engine that allows me to look up directions using a separator (e.g. :) to delineate start and end locations. For example:

gmdir New York City : Pittsburgh

would be inserted into https://www.google.com/maps/dir/New+York+City/Pittsburgh

The regex re=/(.+)\s:\s(.+) would create the two capture groups correctly (from quick testing), but I'm unsure how this could be piped into the URL pattern. I tried adding this to the end of my search i.e.,

gmdir: https://www.google.com/maps/dir/$s{$1}/$s{$2} [re=/(.+)\s:\s(.+)] Google Maps Directions

but that didn't work, so I think I'm misunderstanding how VimiumC handles regex. If anyone has some suggestions, they would be very much welcomed!

1. The [ and ] just mean re= is optional.
2. sorry currently the solution for your issue does exist but is very very tricky (I'll try improving it in v2.12-15 in several months):

So please try:

1. add such a custom search engine

gmdir: vimium://sed/_gmdir\ https://www.google.com/maps/dir/$s{+} \
  https://www.google.com/maps/dir/ re=/^([\w+]+)\/([\w]+)/
  Google Maps Directions

2. add "text substitution rules" into "Auto substitution of various text":

_gmdir@\+(:|%3A)\+@/@i,return
_gmdir@\+([^/+]+)$@/$1@

Explain:

• the main search url is vimium://sed/<sed_key>\ <url>, which executes text substitions defined in Auto substitution of various text
• the prefix and re= will be used by commands like searchInAnother and Vomnibar.activateUrl to parse tab URL and get "search words"
  • the URL prefix before re= is a "prefix matcher" to filter out google maps urls
• _gmdir sed rules will check +:+ firstly, and if no matches then replace the last +word with /word
