https://youtu.be/iOA7NUI-9Xhwvideo-one-

Replace /(^|[^ ])\\-($|[^ ])/g by $1-$2.

$1 refers to the first capturing group (same for $2).

don't you think that it will replace all - where is OP is looking for url only.

Simply use replace method and use below regex to match \- only that contains in URL. I used the logic of space that is not there in URL.

\\-(?=\S)

DEMO

Pattern explanation:

  \\                       '\'
  -                        '-'
  (?=                      look ahead to see if there is:
    \S                       non-whitespace (all but \n, \r, \t, \f, and " ")
  )                        end of look-ahead

what if the dash was at the end of the url/word?

Braj Over a year ago

@OGHaza add $ in pattern \\-(?=\S|$). DEMO

I meant like this demo, but OPs requirements don't make it clear what is necessary. Clearly your original answer solves the problem for his given example.

@OGHaza thanks for your time and testing but there are lots of permutation and combination. I need more info about the rules. Need to verify with OP.
