Visual Studio Code - Regex Insert digit between digits

Question

I want to add "0" at position 7

and make it look like this

I am using this regex :

(0[1-9]0[1-9]0[1-9]0[0-9][1-9])

It finds all strings of this pattern but I don't know how to point it to position 7 , like {7} but how to use it

Thanks

Here is a string ["01","0101","010101","010101001","010102","010103","010104","010105","010105001","010106","010106001","010106002","010106003","01"] convert 010105001 to 0101050001 — Zeeshan Tariq, Feb 11 '18 at 05:34
Its in Visual Studio Code text editor hope it will help you understand the situation. — Zeeshan Tariq, Feb 11 '18 at 05:36
Since, for whatever reason, you seem to want to ignore both answers given below, I will not offer further help on this question. — Tim Biegeleisen, Feb 11 '18 at 05:37
so you want to replace string search from file in code editor right? — Dipak, Feb 11 '18 at 05:38
I have tried this (?<=^\d{6}) in code editor and its not helping the situation, may there is a different method in VS Code. — Zeeshan Tariq, Feb 11 '18 at 05:57
@ZeeshanTariq Try finding `^(\d{6})` and replacing with `${1}0` — Tim Biegeleisen, Feb 11 '18 at 08:43
Try `(?<=^\d{6})` and replace with `0` in the *current* VSCode release. It should work now. — Wiktor Stribiżew, Sep 10 '19 at 12:55

We can try matching the pattern (?<=\d{6}) and replacing with zero. The idea here is to lookbehind the string and insert zero at the seventh position, which occurs when we see six digits behind the current point.

Dim input as string = "010101004"
Dim output as string = Regex.Replace(input, "(?<=^\d{6})", "0")
Console.WriteLine(output)

0101010004

i am using vs code find and replace in multiple files. – Zeeshan Tariq Feb 11 '18 at 05:21
@ZeeshanTariq Then your question was misleading, or maybe I misread it. You should still be able to find `(?<=^\d{6})` and replace with `0`. – Tim Biegeleisen Feb 11 '18 at 05:22
right @TimBiegeleisen I am agreeing with you, because he also not clarify or may be he fails to explain what he wants. – Dipak Feb 11 '18 at 05:32

You should be specific that you only want to look at 9 digit numbers.
If you don't do that, it turns into a rats nest of ambiguity.

Use assertion to insure only 9 digit numbers are looked at.

Based on you're regex, I suggest using this.

Find (?<!\d)((?:0[1-9]){3})(0[0-9][1-9])(?!\d)
Replace ${1}0${2}

Formatted

 (?<! \d )                     # Not a digit behind
 (                             # (1 start), first 6 qualified digits
      (?: 0 [1-9] ){3}
 )                             # (1 end)
 ( 0 [0-9] [1-9] )             # (2), last 3 qualified digits
 (?! \d )                      # Not a digit ahead

You can use infinite-width lookahead and lookbehind without any constraint beginning with Visual Studio Code v.1.31.0 release, and you do not need to set any options for that now.

Find What: (?<=^\d{6})
Replace With: 0
