Specifically, it calls deleteConsecutiveDuplicates on the end product. uniqSort reverses order in an unfortunate way, so we don't use that.
The use-case is when a user has added the same input many times - as it stands, if the history records 30 'top's or whatever, the completion will show 30 'top' entries! This fixes that.
This patch partially implements
http://code.google.com/p/xmonad/issues/detail?id=215
It adds a XPConfig option that, if enabled, hides the completion window
until the user presses Tab once. Default behaviour is preserved.
TODO: If Tab causes a unique completion, continue to hide the completion
window.
- printStringXMF: use the background color for XFT fonts too
- textWidthXMF now returns the text width even with xft fonts
- textExtentsXMF will now return only the ascend and the descent of a
string.
- stringPosition now takes the display too
- add support for UTF-8 locales: if the contrib library is compiled
with the 'with_xft' or the 'with_utf8' option the prompt and the
decoration system will support UTF-8 locales - this requires
utf8-strings.
- now it is possible to decide if the prompt will complete the last
word of the command line or the whole line (default is the last
word);
- completing the last word can be fine tuned by implementing
'commandToComplete' and 'completionToCommand': see comments for
details;
- move mkComplFunFromList' from TagWindows to Prompt.
See my email to mailing list. This will slightly break anyone who upgrades while running and expects to see their prompt history, and leave a stray file, I think, but nothing else, and it'll permanently improve tab-completion, and is tidier.
XMonad.Prompt.Input is a new module which provides a framework for
prompting the user for input and passing it along to some other action,
useful for building actions which require user input.
XMonad.Prompt.Email is a simple example of the use of XMonad.Prompt.Input,
which prompts the user for a recipient, subject, and body, and sends
a one-line email.
I also made a small refactoring to XMonad.Prompt in order to support
XMonad.Prompt.Input.
