A plain text viewer which can hide lines that meet specified regexps

  • 772

Each time I've been looking for "something I don't know exactly what" in big text file, e.g. log-file, huge shell script, I wish to hide all the lines of certain types.

I wish to select certain lines with a set of regexps and either hide them or highlight.

It would be nice if I could select line blocks e.g. those lines between "function ...() {" and corresponding "}"

can you suggest me such a viewer?

  2. Have you tried regexxer? It can highlight matches and you can jump from match to match but it won't filter just matches. Similarly like gnome-system-log but more easy to use

    I could also show you how to filter regex matches (display only matching lines) in SciTE editor, with small LUA script, and I imagine many others can show you how to with vim or emacs, but you didn't mention which editor you use.

  3. You can try Geany [GUI]

    regx for multiple line is not supported bust you can use - and + to hide/show portion of text such as functions ({...}).

    It support may languages including xml.

  4. Have you tried vim with folds? It can fold code blocks very well.

    :set foldmethod=indent

    This command sets fold method based on indentation.
