Find-Replace using LaTeX commands
Tim Lahey
I've run into some problems with the find-replace command. Words using
\r and \t have problems. I'm assuming they're being interpreted as
something else. Can I change things so they're just text?
Thanks,
Tim.

If I understand what you are asking correctly, then yes:
\r = the line ending character
\t = the tab character
if you want to find the *literal* string "\r", then you would search
for it this way:
\\r
The "\" char escapes whatever comes next.

It helps to understand that when bbedit has a file open for editing the entire document is stored as 16 bit UTF characters. The \ character used as an escape elsewhere is essentially never there at all. (Editing a shell script might be an exception to that.) Also all input line ends are represented as 0X 000D, the standard for Apple of old.
If your external text uses 0x0A or a 0D0A pair they're 0x000D in memory. Only one kind of line end is allowed in a file coming in. BBEdit takes a guess at which one is the real one if your source has a plurality of them as you might find in a teletype message of old.

That's unfortunate. LaTeX commands are built around using \ so there
are commands like \textit which is used to make text italic, \tan (for
printing tan properly) and I have custom commands like \rV. Doing
find-replace with the standard BBEdit find-replace dialog is very
annoying since BBEdit is making me do more work since I can't just
select text and do a find based upon it.
Cheers,
Tim.

characters so I don't need to do that. Since most of my text is LaTeX,
it's quite annoying to have a search error and then realise that
there's a special character and escape it.
Cheers,
Tim.

I don't understand why not. When you select some text with a
backslash in it, and choose "Use Selection for Find", it gets
escaped correctly so that searches will find that text (assuming
it exists where you're searching). What have I missed?

Someday I'll look back on all this and laugh... until they
sedate me.

I didn't know about "Use Selection for Find" so I've been doing a cut
and paste into the Find dialog. It's still kind of annoying on the
replace side since I don't think of \r or \t except as LaTeX strings
so I've accidentally added return characters into my text in the past.
So, I'm guessing there isn't a way to disable \r and \t as special
characters so we don't need to escape them. That's unfortunate.
Thanks,
Tim.

"Use Selection for Replace" works, as well. Both share the
benefit of not messing with what's on your Clipboard.
