Protein text to csv?

[Stephen Taylor]

Hi, first time poster but long-time BBEdit user. I have a text file of a 
protein, which I'd like to convert to csv by inserting a comma between each 
character, like so:

MADEEKLP  -> M,A,D,E,E,K,L,P, ...

And some lines (for secondary structure) have lots of spaces:

  S TTE ->  , , S, , , ,T,T,E,E,E,E, ...

Is there a way to do this in BBEdit? I hacked together a simple javascript 
to do it, but then I have to run that as a local webpage; it would be great 
just to do it within BBEdit. Sorry if this is a dumb question, and thanks 
for any responses!

Find pattern: (.)

Done (if I understood you correctly)

This makes

Looks like a fairly simple thing to do with Find/Replace, e.g.,

Find:
([A-Z])

Replace:
\1,

[A-Z] matches a single upper case ascii letter.
The parens capture that matched letter.
The \1 in the replacement is that captured value (the first one, 
and in this case the only captured value).


This will do most of your work, although you might not want the 
comma at the very end after the the very last letter. And there 
might be other edge cases.


If your JS script works well, note that BBEdit can run scripts 
written with Apple's script editor, and - unknown to many - 
Apple's Script Editor accepts scripts written in javascript as 
well as those written in AppleScript. So you might want to check 
that out. A script can often be more versatile and robust than 
using find/replace.

It seems to me to be a simple regex (Regular Expressions) search and
replace with BBEdit’s Find.
First you want to look for upper-case letters A-Z or a space. That would be
[A-Z ] note the space after Z.

Then you want to capture that for later use.
([A-Z ])

Replace it with \1 and a comma
\1,

Turn on Grep and Replace All.
Someone can correct me if I'm wrong.
