    Terminal with parenthesis matching (highlight)

    Hi all,
    I write a lot of short scripts on the fly at the command line. Basically perl one liners, but I often get carried away and end up having several lines of code. Is there any terminal app out there that can do emacs or vi style parenthesis and brackets highlighting?

    well why not use vi as your line editing mode (set -o vi)

    then when typing a long command, hit ESC and v brings your line into vi where you can edit to your hearts content (including brace matching) before :wq exits back to the shell and runs your command

    grrrrr I've managed to stick to emacs and avoid vi for the past decade! You're telling me I have to betray my principles!?? Real programmers use emacs and all that.... Is there a way to do the same with emacs instead?

    In any case, joking apart, thanks for the answer. I'll give it a try.

    Or use one of the shell modes in emacs, shell or eshell. You get parenthesis matching for free, and you can easily move over to a buffer in cperl-mode if you need to.

    OK, that sounds interesting. I'm not sure what you mean though. Will I need to copy/paste between the terminal and an emacs window? Open a command line emacs? How would I execute the command once I am done writing it?

    Try this:

    Code:
    set -o emacs
    I don't know if it'll work, but worth a shot, I suppose.

    Well, I tried both set -o vi and emacs and neither seems to be doing anything. Will this work for bash or is it specific to Korn shell?

    It's a bash shell environment varable as far as I know.

    Actually, set -o vi seems to do something. I seem to be in a vi environment (I had to type i to edit) and :wq got me back to my command. Ok, so far so good, but there was no brace matching.

    set -o emacs got me back to my (normal?) mode, where Ctrl+K kills a line, Ctrl=W a word etc etc.

    So.. is that.. good?

    I stick to vi mostly, since I'm not fond of emacs.
