Sparse tree using regexp

Sparse tree using regexp

[Juri Artamonov]

[-- Attachment #1.1: Type: text/plain, Size: 469 bytes --]

Hello,

I have aquamacs and I have org file. I would like to leave lines that which
contains only words TODO or INPROGRESS.

I do Ctrl-C + / + / and then enter regular expression. If I enter TODO or
just INPROGRESS then it works but when I try to enter TODO|INPROGRESS or
TODO\|INPROGRESS in order to see records containing one of these words then
no records are shown.

Could you please advice how to use regexp here for orgmode?

Thank you,
                    Juri.

what about '\(TODO\)\|\(INPROGRESS\)'?

But shouldn't it be possible to get the sparse tree with the simpler
"TODO\|INPROGRESS" regex anyway? I tried it and it worked as expected
(with GNU Emacs on Linux). The OP could also try using the Todo kwd
option, `C-c / T'. When prompted, a simple expression like
"TODO|INPROGRESS" should work. (note the absence of backslash).

Maybe some variable setting is interfering with the matching, or maybe
its an Aquamacs bug. Just a few thoughts.

Hello Marco,

this way it's working. Do you know why it's required additional brackets and
it's handling?

Thank you,
                  Juri.

that's good.

i just reactivated my regexp-brain-cells and saw the brackets. ;)
possibly you want to dive into regexps.  then you will get aquainted
with the brackets for grouping.

but ali noticed that you don't need brackets on his box.  maybe it's a
bug (or inconvenience) in aquamacs.  see his post and hopefully some
follow-ups.

ciao

The parentheses are redundant. Perhaps it is an Aquamacs issue. With
GnuEmacs 24 on Linux, the following search works fine:

C-c / / TODO\|STARTED

That said, for this use, a TODO keyword search will be quicker and more
accurate, as the regexp search above will match "todo" or "started"
anywhere in the buffer. Here's the todo search:

C-c / T TODO|STARTED

Best,
Matt
