Mac Forum / Applications / Mac Applications / May 2008GREP pattern wanted
In Textwrangler or BBEdit what would be a GREP pattern to replace either of two words with specific words depending on which word was found? For example, I want the word "red" replaced with "crimson" and also want "gray" replaced by "grey". How to make one pattern to get this in one pass. It is easy to make two and have two passes. In other words, what would have to be put into the Search for box and what in the Replace with box? > In Textwrangler or BBEdit what would be a GREP pattern to replace > either of two words with specific words depending on which word was [quoted text clipped - 3 lines] > words, what would have to be put into the Search for box and what in > the Replace with box? It is a lot easier to do it in two passes. Is there any reason you need to do it in one pass?

Is there any reason you > need to do it in one pass? Perhaps she is wanting to do this sort of thing a lot and doing it in two passes comes to double the effort. In BBedit at least, one can save patterns. But to get to them one sometimes needs to scroll. To do this twice, to slightly different patterns and repeatedly is obviously more work. But I agree that if it is just the odd one off, much much easier to do it in two swoops than to spend time tooling up and well, basically w.nking. A case from my own experience is where I need to replace html mark-up inside code tags where I need to be exhibiting source on the web page. It would be a bore making two passes to replace the "<" and ">" each time with respectively "<" and ">". I get by these days with one search pattern and replace, which seems to work: Find: <([^<>]+)> Replace: \<\1\> but this is a special case.

But you are welcome to elaborate with details.

If your file is plain text (which I'd assume it is, since you're editing in TextWrangler), you can always pass it through sed: sed -e 's/red/crimson/g;s/gray/grey/g' test.txt Signature-L > If your file is plain text (which I'd assume it is, since you're > editing in TextWrangler), you can always pass it through sed: sed -e > 's/red/crimson/g;s/gray/grey/g' test.txt Can you say more about this please? Starting with I am looking at a Textwrangler plain text file and I get something called sed and pass something through it...

You save the file to disk, then open a Terminal window, and type: sed 's/red/crimson/g;s/gray/grey/g' filename.txt > filename-new.txt Now filename-new.txt is the version with all the substitutions.
