Excessive file completion

Hi

Whenever I try to complete file or dir names, fish prints suggestions which include part of the path I've already entered.

E.g. when I'm trying to complete /Applications/, fish suggests "…ications/Safari.app/"

Is it possible to configure fish to exclude "…ications/" from suggestions completely?

Best Regards,

Ilya Kulakov

Suffix pattern removing

Hi,

How can I perform suffix removal as this (bash) command:

nameis=${dataset%.*}

if dataset is a filename with extension (say foo.txt), nameis will only contain "foo".

Is there a way to do that with fish?

Thanks,

Fish version of [[?

I want to compare a string with a wildcard, as in "[[ $1 == *.tar.gz ]]"

How can I match strings with wildcards?

Re: Fedora package

Thanks Laurence. If you need a spec file for creating RPM packages, you can get it from repository at https://build.opensuse.org/package/show?package=fish-shell&project=home%3Asiteshwar

Working on a new terminal emulator

Hi all,

I'm working on this: https://vimeo.com/68400623
It's still a prototype but maybe... it could work.

I started from bash.. then I moved to zsh.. now I've just discovered
fish... so I want to integrate it in xpipe.
I just take a quick look at the docs... but it's a big stuff and
probably it will require more time and attention. So far I didn't find
what I'm looking for. So I came here to say hello and ask some basic
question not found there...
1) Completion: is it possible to wrap the completion output inside
some escape codes? Each entry. I use some custom escape codes to catch
any completion output  and display it in the graphical way... In zsh I
add also some useful info as PWD and the complete line buffer. My
escape code is \033|(whatever). It's not used in the vt100 standard...
Also it would be perfect to know (in case of file completion) the
exact type of any voice: file, directory, executable. At the end of
this email I will add an example of what I have done in zsh.
2) preexec: again, in zsh there is a preexec() function called just
after the execution of any command... and before any output. What I
need is to prepare the "next line" of my terminal to handle the result
of the command: so I need to know if the user has run git, apt, wget
or whatever. How?

Example...

mario <at> squit $ ls /home/me[TAB PRESS]
\033|.1 "ls /home/me", $PWD and some other info \033|.2
\033|./Dropbox (directory)   \033|.2
\033|./script.sh (executable)   \033|.2
\033|./file.txt (standar dfile)   \033|.2

mario <at> squit $ wget http://www.xxx.com/bigfile[ENTER PRESS]
\033|.3 "wget http://www.xxx.com/bigfile", $PWD and some other info \033|.2
...the output of wget...

Tnx
Mario

Proper behavior on very long prompt?

Hi,

I’ve noticed that if the prompt is very long,
(longer than the window width), it’ll become
a single ‘>’, and it even won’t show a second
line.

What’s the consideration behind it?
I don’t think it’s friendly to users.
I tried to google, but found nothing.

Is there any configuration to change that?
Or, can I check if it happens, so I can try to
show something abbreviated instead?

Thanks! :)

fish and rvm on lubuntu latest

I've installed rvm.fish :

yt at GERICOM in ~

↪ cat .config/fish/functions/rvm.fish

function rvm -d 'Ruby enVironment Manager'

# run RVM and capture the resulting environment

set -l env_file (mktemp -t rvm.fish.XXXXXXXXXX)

bash -c 'source ~/.rvm/scripts/rvm; rvm "$ <at> "; status=$?; env > "$0"; exit $status' $env_file $argv

# apply rvm_* and *PATH variables from the captured environment

and eval (grep '^rvm\|^[^=]*PATH\|^GEM_HOME' $env_file | grep -v '_clr=' | sed '/^[^=]*PATH/y/:/ /; s/^/set -xg /; s/=/ /; s/$/ ;/; s/(//; s/)//')

# clean up

rm -f $env_file

Equivalent of bash's $0?

Is there a fish equivalent of $0 (the full pathname of the running
script)?  (Or indeed any way to determine what directory a script is
in, from within the script itself?)

previous command completion bug (ubuntu)

I've just noticed some odd behaviour around previous command completion 
on Ubuntu 12.04 with the apt-get fish package (2.0.0).

When the greyed our part of the command makes the command longer that 
the available space the greyed out part shows '...', and when the typed 
part of the command is too long the the command is pushed down a line 
however the greyed out part of the command doesn't show at all. These 
problems only happen when the line is not long enough

http://dl.dropbox.com/u/45079992/Screenshots/y500ba1ui~q5.png 
<http://dl.dropbox.com/u/45079992/Screenshots/y500ba1ui%7Eq5.png>
line long enough, expected behaviour

http://dl.dropbox.com/u/45079992/Screenshots/jzd4w23oy1d8.png
enough room for typed chars ('fin') but not enough room for greyed out 
part, it shows ... and doesn't move down to next line

http://dl.dropbox.com/u/45079992/Screenshots/v45_x0v642_5.png
then when there's not enough room for the typed part of the command it 
does drop down to the next line but doesn't show the greyed out part at all

http://dl.dropbox.com/u/45079992/Screenshots/hq1~dicecd6c.png 
<http://dl.dropbox.com/u/45079992/Screenshots/hq1%7Edicecd6c.png>
after pressing ctrl+f the command is completed so that works, it's just 
not showing what the completion would be

http://dl.dropbox.com/u/45079992/Screenshots/oqhw127gvn_s.png
screenshot from my mac (1.23.1, an old fishfish version) which shows the 
expected behaviour (note there is enough room for the typed chars ('fi') 
on the previous line however the command is pushed down to the next line 
because there's not enough room for the greyed out part

Has anyone seen this behaviour before? Should I create an issue on github?

Peter

bug in git-prompt

Good evening

Using the git prompt available through fish_config, I never received any prompt. This was in a git dir where I was not on any branch. Switching to branch master fixed the issue.

Cheers, Sindre
