How to remove spaces between words using regular expression in sublime text?

I have some values look like these:

$lang['Delivery Charge'] = 'Delivery Charge';

$lang['Frequently Asked Questions'] = 'Frequently Asked Questions';

I am using this regular expression to select the variable index:

\$lang\['.*'\]

Now how can I replace the spaces between words for only the variable indexes not in values.

I mean my final result will look like:

$lang['DeliveryCharge'] = 'Delivery Charge';

$lang['FrequentlyAskedQuestions'] = 'Frequently Asked Questions';

Thanks in advance!

You could use

(?:\$\w+\['|\G(?!^))\w+\K\h+

Explanation

  • (?: Non capture group
    • \$\w+\[' Match $ and 1+ word chars and ['
    • | Or
    • \G(?!^) Assert the position at the end of the previous match, not at the start
  • ) Close non capture group
  • \w+ Match 1+ word chars
  • \K\h+ Reset the match buffer and match 1+ horizontal whitespace chars

And replace with an empty string

To also check for a closing ] , where there can not be square brackets in between, you could add a positive lookahead:

(?:\$\w+\['|\G(?!^))\w+\K\h+(?=[^][]*'])
