vim and debugger history

jpl has asked for the wisdom of the Perl Monks concerning the following question:

I use the perl debugger a lot as a calculator, say when I'm doing exercises on Khan Academy. In my linux/ubuntu perl 5.22.1 environment, I can edit my debugger command line history using all the familiar (to me) vim commands, like cw to change the word "sin" to "cos", and . to change another instance in the same way. I recently went on the road with a MacBook, and found that editing the command line history didn't work there. I went so far as to install a new gcc compiler so I could build a new perl, and I installed Term::ReadLine::Perl, Term::ReadLine::Gnu and Term::ReadKey from CPAN. That gave me basic command line editing capabilities, but not the vim commands. I have no recollection of doing anything exotic to get vim and the debugger to play nice on linux, but I haven't turned up anything for how to do so in the OSX world. Suggestions (other than "use a different editor, Stupid") would be much appreciated.

You have to set 'vi' mode in your ~/.inputrc file. Such has worked for me in the Perl debugger, though I don't recall the details. The web suggests you try: `set editing-mode vi set keymap vi-command` [download] - tye	[reply] [d/l]

The http://vim.wikia.com/wiki/Use_vi_shortcuts_in_terminal hit the mark. All I had to do was adjust my ~/.inputrc file on the Mac. This was last modified in 2006(!!!) on my linux box, so it's not a surprise that it was not fresh in my mind. Thanks to all.	[reply]

It sounds as if you are using the debugger inside VIM (is there even an integration available?ł), but I think you are calling vim from the debugger. (right?) AFAIR in the latter case you are able to customize an editor inside the debugger to edit multiple lines˛, wouldn't surprise me if Mac doesn't like VIM.° Or are you talking about switching only the line edit commands from GNU (i.e. emacs) to VI? IIRC there is a `set` option to do so. see http://vim.wikia.com/wiki/Use_vi_shortcuts_in_terminal Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!} °) understandably as an emacser ;-) ˛) seems what I remebered was the pager support, which doesn't really allow to edit the history though! see `DB<1> h \| \|dbcmd Run debugger command, piping DB::OUT to current pager. \|\|dbcmd Same as \|dbcmd but DB::OUT is temporarily select()ed as + well.` [download] ł) a sure Fritz Mehner of course :) http://www.vim.org/scripts/script.php?script_id=556	[reply] [d/l] [select]

> IIRC there is a set option to do so. > see http://vim.wikia.com/wiki/Use_vi_shortcuts_in_terminal you can also try to do it interactively `DB<1>!!set -o vi` [download] tested on ubuntu and bash update though the result feels strange but I'm not a vi expert. or to be more precise of the vi-emulation in gnu-readline Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l]

Vim works on Mac OSX very well. Unlike your politics.	[reply]

Never denied it, Jeff! I was only talking about Mac politics to NOT favour it in default settings. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!} PS: Sorry for feeding...	[reply]
