Hi all,
I'm new xmonad user (been using it for 2 months) and one feature I am missing is searching in the prompt history.
I use various prompts like Man, Ssh, Shell and Window and in addition to going through the history line by line I would like to be able to type a few characters, press some key (e.g. Ctrl+Up) and the prompt would seek to the first such occurence in the prompt history. For those of you who know ion, that is it[*]
Is it possible in xmonad? As I am not a programmer, I just craft my xmonad.hs by copying parts of setup I find on the internet without really understanding them - either they work or they don't. So far I did not find anything resembling this functionality.
Regards, [*] I used ion window manager since the first version (2002?) for many years until Tuomo changed the licence and it dropped out of Debian. I briefly tried Awesome, which was lacking some of the features (e.g. scratchpad) and that lead me to xmonad because its defaults suit me better.
If you try out Actions.Search, you'll notice that tab-completion is done on only prior search queries and not files or hosts or the others you've tried. If you look at Prompt.hs you'll see some completion functions like: -- | 'historyCompletion' provides a canned completion function much like -- 'getShellCompl'; you pass it to mkXPrompt, and it will make completions work -- from the query history stored in ~\/.xmonad\/history. historyCompletion :: ComplFunction historyCompletion = historyCompletionP (const True) If you wanted to make some uber completion, you could combine completion functions. That is, the guts tend to look something like this: getShellCompl :: [String] -> String -> IO [String] If we have [String] for shell-only completions, and we have [String] for just history completions, we could combine the 2 lists with ++ or write an interleave function like interleave [] y = y interleave x [] = x interleave (x:xs) (y:ys) = x : y : interleave xs ys You could also rewrite the promptKeyMap field in an XPConfig to change the default binding: , (xK_Up, moveHistory W.focusDown') Or you could reset the completionKey field to Up instead of Tab. -- gwern
