VSCode Search Replace RegEx

I am flatting an Angular translation file and I need to do a search replace in VScode on the translate key. I need to clip off all that comes before the final key and return that to the replace. The keys will only be at most 3 levels deep. The words below of key and keepThisInReplace are arbitrary and will be different words. Examples below.

Search String Options:

'key1.keepThisInReplace1' | translate
'key1.key2.keepThisInReplace2' | translate
'key1.key2.key3.keepThisInReplace3' | translate
'anyWord.AndLevelAmount.UpTo3AtLeast.anyWordToKeep' | translate

Do not find in search:

'../../assets/images/
'./../assets/images/
'.......
'path').join
'staging.site
etc...

The above should be replaced as:

'keepThisInReplace1' | translate
'keepThisInReplace2' | translate
'keepThisInReplace3' | translate
'anyWordToKeep' | translate

What I am trying that is not working - Looks like '\w[^.].\w*.*\w*. will work. will almost work - picks up on 'path').join and 'staging.site still.

The keys above all do have {{ in front of them. But if I lock in on the {{ then I have to return it in the replace. Example = {{ key1.key2.keeptext | translate }} = {{ keeptext | translate }}

You might use a non capturing group with a quantifier that repeats 1 - 3 times 1+ word characters followed by a dot and make sure multi line is enabled using the anchors ^$.

In the replacement use a '

^'(?:\w+\.){1,3}(?=\w+'\s+\|\s+translate$)

If the string can be anywhere in the file your could omit the anchors and use a word boundary \b after translate.

'(?:\w+\.){1,3}(?=\w+'\s+\|\s+translate\b)

Explanation

  • ^ Start of string
  • (?:\w+\.){1,3} Repeat 1 - 3 times matching 1+ word chars and a dot
  • (?= Positive lookahead, assert what is directly on the right is
    • \w+'\s+ Match 1+ word chars, ' and 1+ whitespace chars
    • \| Match |
    • \s+translate$ Match 1+ whitespace chars, translate and assert end of the string
  • ) Close positive lookahead

Regex demo

Another option instead of a positive lookahead is using 2 capturing groups.

In the replacement use group 1 and group 2 $1$2

^(')(?:\w+\.){1,3}(\w+'\s+\|\s+translate$)

'.*\. to ' should be all you need. This will replace all strings that match a tick followed by any number of characters and then a dot.

if you want to be more specific you can use this

'\w*\.*\w*\.*\w*\.

this will match up to 3 dots with words in between.

EDIT

I tried to make it more specific and here is what I came up with:

'.+\.(?=\w*'\s*\|\s*translate)

This uses a lookahead to make sure the matched string is followed by a word and then ' | translate. Do you think this is specific enough?
