display information in seperate buffer

display information in seperate buffer

[Fabian Braennstroem]

Hi,

I wonder if there exist any package that filters out some
information about certain files using dired and display
those in a separate buffer.
I mean I would like to extract lines with certain keywords
(e.g. fluid and turbulence) or special lines from the file
which is currently 'active' in dired. It is probably similar
to some mbox filtering. And more advanced: if two files are
'active/marked' then show the infos in separate windows and
highlight the differences (probably like ediff-buffers).

Greetings, Fabian

Do you know about `occur', `multi-occur' and `dired-do-igrep'
(from igrep.el)?  They should be a good starting point.

No, never heard of occur and my first attempt to use the igrep did not work.
Thanks, I will take a look at it.

Occur/Multi-occur looks great and igrep was just an old version :-) I always
had problems to find the newest packages; it looks like that
emacswiki has some of the newest ones...

One question to multi-occur, right now it displays the
matching lines for the given regexp for the chosen files, which is
fine, but am I able to run some kine of ediff so multi-occur
highlights the different listed lines, e.g.:

  20 matches for "inlet" in buffer: *Occur*<2>
   35:       inletvelocity = 10 [m/s]
   38:       inlet = 2
  9 matches for "inlet" in buffer: keps_small_301.out
   36:       inletvelocity = 20 [m/s]
   40:       inlet = 2

So it would highlight the lines containing 'inletvelocity'!?

Run ediff-buffers normally, then use `#f' to focus it on the differences
you're interested in (those that match "inletvelocity").
