regular expresions find and replace

Glider (IDE)

Hi,

I just started using regular expressions in my search and replace and they are really handy.

an example:

I set my x position like this for my iPhone apps.

[lua]

puppet.x=68

[/lua]

if I have a lot of different variables set up like that, but all with different x positions. I can easily change them for my iPad version like this:

[lua]

–find this

.x=(.*)

–replace with this:

.x=$1*2+35

[/lua]

This will convert the coordinates to the correct iPad set up in my case.

Now I want to use another one in this situation, but can’t get it to work as intended:

I have the following image with width and height:

[lua]

(group,“image@2x.png”,86,184)

[/lua]

I want to add *2 to the width and height for all my images in one go.

I can use the follwoing line for that

[lua]

–find

",(.*),(.*)

–replace with 

",($1)*2,($2)*2

[/lua]

but if I do this it selects the closing brace, which I do not want.

so I hoped it would select ",86,184

but it selects ",86,184)

ANy ideas how I can fix this?

Hello Juf,

How about this

--find ",(\d\*),(\d\*) --replace with ",($1)\*2,($2)\*2

the \d will match any digit, the * means 0 or more times. We highly suggest you learn about regex as it is a good tool to have under your belt. You can learn more from various resources on the web like this one:

Thanks,

I never really knew about regular expressions for search or code for that matter never needed them. I always saw the options in software to do searches or in code. 

So I started looking into it yesterday.

I found out some myself but most things I saw where really confusing and used html as an example. The amount of brackets and special characters in it was so overwhelming that I had a hard time figuring it out.

I do know that they are really powerfull and all programmers need to learn them. But I baby steps for me.
