Writing a regex to find translations in a laravel project

I have written a regex pattern:

(trans|trans_choice|Lang::get|Lang::choice|Lang::trans|Lang::transChoice|@lang|@choice)\(([\'"]([a-zA-Z0-9_-]+([.][^)\'"]+?)+)[\'"])(\s?,\s?.*)*?[\)\]];?

For targeting laravel translation strings such as:

trans('email.subject)
@lang('email.confirm-email-address-button')

But I have trouble figuring out how to target translation strings that have slashes in them such as this:

@lang('emails/order-received.edit-order-button')

You may use

(trans(?:_choice)?|Lang::(?:get|choice|trans(?:Choice)?)|@(?:lang|choice))\(([\'"]([^\'"]+)[\'"])[)\]];?

See the regex demo.

Details

  • (trans(?:_choice)?|Lang::(?:get|choice|trans(?:Choice)?)|@(?:lang|choice)) - Group 1:
    • trans(?:_choice)? - trans followed optionally with _choice
    • | - or
    • Lang::(?:get|choice|trans(?:Choice)?) - Lang:: followed with get, choice, trans or transChoice
    • | - or
    • @(?:lang|choice) - @ followed with lang or choice
  • \( - a ( char
  • ([\'"]([^\'"]+)[\'"]) - Group 2: ' or ", then Group 3 matching any 1+ chars other than ' and " and then " or '
  • [)\]] - a ) or ] char
  • ;? - an optional ;.

NOTE: Parsing code with one regex might be too fragile. Please consider using this regex in a more complex solution or using a dedicated parser if any exists.
