on OSX, and ubuntu 12.04, with the beta release, I ran:

$ while true
     echo hi
     sleep 2
  end

After a few iterations, I pressed ctrl+c to interrupt the loop, then pressed ctrl+c repeatedly, even holding it down

The child process was reliably terminated, but never the loop

Eventually, I had to kill the fish process from another terminal

In Bash on Linux:
`while true; do sleep 1; echo hi; done``
handles keyboard interrupts as expected

cd command should auto suggest name of directory to be entered from arguments passed to it.
Right now cd command only shows completions from history.

This is on Ubuntu 10.04, 64 bits, with fishfish built from source.

In fish_config_interactive, we use 'which' to detect command-not-found.
The problem is, 'which' is not so portable, and in particular its exit status isn't always significant.
This could be changed to be 'command -v' to safer.
Also 'command' should support the -v flag.

A secondary problem is that the -s flag looks to be BSD specific.

When typing "ssh " followed with a tab, it autocompletes to listing the current directory instead of available hosts in my ~/.ssh/known_hosts config.

when executing "__fish_print_hostnames" it does show hosts but they do not work in the autocompletion.

Axel reports:

"On my machine, most key bindings seem to be broken. ^K does not kill, ^W
does remove text, but it seems not to be added to the actual kill ring. No
searching with up-arrow and down-arrow. Left arrow and right arrow do not
move around in the CD history when used on an empty command line. The bind
builtin implies that the bindings are still there, and the code to handle
these these commands seem to still be there in input*.cpp, so I guess
something is broken? (built from a tarball on Ubuntu 12.04)"

Run this: false ; and sdlkfjsdklf
This shows an error: Unknown command 'sdlkfjsdklf'
The short-circuit could suppress this error message, and perhaps even discovering that the command does not exist.

If I try to run echo $?, I get the error message

fish: The '$' character begins a variable name. The character '@', which
directly followed a '$', is not allowed as a part of a variable name, and
variable names may not be zero characters long. To learn more about variable
expansion in fish, type 'help expand-variable'.

Same thing if I use $*. That garbage character is U+F400 for ? and U+F401 for *. Other characters I've tried, including ,./@!, print a correct error message.

This issue tracks considering integrating with cdargs.

"Hello,

Fish looks nice and sweet. I hope it will succeed in changing the shell landscape for ever :).

I've just written a function file for cdargs the directory alias manager, aliases for cv and ca and supports completion for the cv command.

Available here:

https://gist.github.com/2881699

Cheers,
"

Here is the code:

function ca
command cdargs --add=":$argv:$PWD"
end
function cv
cdargs "$argv"; and cd (cat "$HOME/.cdargsresult")
end

function _cdargs_completion
cat ~/.cdargs | cut -d' ' -f1 | xargs echo
end

After picking a suggested path, the whitespaces and special chars should be escaped

ls should know about directories, just like cd

I've found a strange place in file output.cpp line 276:

if( ! c2.is_normal() &&
! c2.is_ignore())
{
/*
Background is set
*/
bg_set=1;
c = (c2==rgb_color_t::white())?rgb_color_t::black():rgb_color_t::white();
}

It means that it resets the foreground if background is set. Is there any particular reason of doing it? Or it's just a sort of typo?

Currently the hotkey to accept autosuggestions is right arrow or control-F. This ought to be configurable.

when typing a % it will print:

Warning: principal_parser called off of main thread. Break on debug_thread_error to debug.

set fish_color_autosuggestion 000000 --background FFFFFF

This should show a white background color with autosuggestions, but does not.

The default prompt in fish is quite expensive (something like 10 fork calls). Let's make one that's still interesting but cheaper.

Let's migrate to posix_spawn.

• It will force us to get rid of all of the dangerous "post-fork" code.
• It will be faster on OS X and possibly BSDs.

fish needs a history built-in, for things like deleting unwanted history items. bash and zsh both have this.

history --help
troff: fatal error: can't open `/usr/local/share/fish/man/history.1': No such file or directory

That's not good.

I think it worth supporting fish_user_keybindings function, which should be loaded right after fish_default_keybindings to support user key bindings.

From http://comments.gmane.org/gmane.comp.shells.fish.user/3081:

"Consider this foo.fish file:

complete --command foo --no-files --short-option a --long-option 'an_example' --description 'example A'
complete --command foo --no-files --arguments '(sleep 5s)' --description 'slept'

Type in the shell

foo -

and press tab. 5 seconds pass, before we get the result. If I delete the second line from foo.fish, the result is instantanious. AFAIK, the --arguments should not be executed when fish is completing options for a command."

It would be nice if completions were not blocking. Perhaps they could be executed in a cancelable subshell.

If I try to run echo \uF400 this is treated identically to echo ?. Similarly \uF401 is treated as *. \uF402 is treated as some other character but I have no idea what; trying echo \uF402 hangs until I type ^C, at which point it says fish: Could not expand string '\uF402'.

This behaviour have been in fish too, and annoyed me from time to time, but not very often.

$ cd /
$ cd e<tab>
// plenty of errors (fish didn't get this output)

# This will appear, but "etc/" will be red as in "directory does not exist":
$ cd etc/

# If you run pwd instead of the cd you got, you will notice that you're in your home directory
$ pwd
/home/etu

I can also note that this only affect cd as far as I noticed.

This bug tracks reinstating implicit cd in some form. Implicit cd is where you can switch to a directory by just typing its path, without explicitly typing cd. It's as if you execute the directory.

In decreasing order of implicitness:

1. Restore it to its state in fish trunk: implicit cd is active and respects CDPATH
2. Implicit cd only works for the current directory. CDPATH would still be respected, but only when using cd explicitly.
3. Implicit cd only works for paths starting with a dot, slash, or tilde
4. Implicit cd only works for '..' (and perhaps ../.., etc.)
5. No implicit cd.

There's also potential to make this configurable in some way.

Feel free to pile on with your desires / perspectives.

Snow Leopard's terminal is misidentified as supporting term256. It doesn't.

This works:

$ function etu
    echo "mooooo"
end
$ etu
mooooo
$

This does not work:

$ funced etu
etu> function etu
    echo "mooooo"
end
$ etu
fish: Unknown command "etu"
$

The function was never made available when using funced.

This also makes that you can't use funcsave for some function edited with funced -- because the functions doesn't exist.

Run this:

bar

Then this:

You get two items foo\ and bar; there should only be one.

2. See unexpected completions

They shouldn't show up in this case.

The internalize scripts build phase internalizes far too much, including fish_prompt. We should measure to see what benefit, if any, is being derived from it, and restrict it to only those functions that really ought not to be changed (if any).

Now that we have a history built-in, we should support deleting history from the web configuration interface.

Method wgetopt() in wgetopt.cpp fails with segment violation. Here is a small snippet of code which may help in reproducing bug :

....
static const wchar_t short_options[] = L"cdanrwps";

int opt = 0;

while((opt = wgetopt( argc, argv, short_options )) != -1)
{

....

fish_title applies correctly to the window title, but not the tab title. This is due to this code in reader.cpp:

writestr( L"\x1b]2;" );

2: Window title
1: Tab title
0: Both window and tab title

I think removing the 2 is equivalent to setting it to 0, so that's probably what we ought to do.

Imagine a server that stores color configurations.

• Users could vote on popular ones (think Adobe Kuler)
• Users could upload their own preferred scheme, and so have access to it on all their machines

This would be integrated into the web config page.

If you type a command that's not valid at all, maybe we can avoid autosuggesting it. This could be handled by a "special" handler in highlight.cpp

Functions in ~/.config/fish/functions/ does not work if there is a command called the same thing, this breaks my custom fish_prompt for example

pants writes:

There doesn't seem to be one of these available in the archives, and
it's the thing I've missed most since moving from zsh, so I figured I'd
really get fishy and write it. Appending the following to your scp.fish
(or making an alternate scp.fish in .config/fish/completions) will allow
you to preform tab completion of remote paths for scp! Identical
completions could also provide identical functionality in rsync. It
would be nice to integrate fish's built-in description methods, but I
can't think of a way to do that without ensuring fish is installed on
the remote system (not a general fix) or mounting an sshfs (gross).

Code:
complete -c scp -d "Remote Path" -n "echo (commandline -ct)|sgrep -o '.*:';and true" -a "

(
#Prepend any user@host information supplied before the remote completion
echo (commandline -ct)|sgrep -o '.:'
)(
#Get the list of remote files from the specified ssh server
ssh -o "BatchMode yes" (echo (commandline -ct)|sed -ne 's/(.):./\1/p') ls\ -d\ (echo (commandline -ct)|sed -ne 's/.://p')*
)

"

Enjoy!

As we are multithreaded, sigprocmask should instead be pthread_sigmask

I have my own custom defined ~/.config/fish/functions/fish_prompt.fish together with plenty of other functions. But my fish does not seem to care about the config in my homedirectory.

If I do funced fish_prompt I get the defaultprompt to edit, and since the bug #16, I can't use funcsave to save the edited prompt.

But it still does not matter if I take nano(or any editor) to edit the functionfile if theres a function existing on system-level in fish.

Running OS X Lion 10.7.4, process expansions leads to the following warning message:

Warning: principal_parser called off of main thread. Break on debug_thread_error to debug.

This message will show up again with each additional keystroke until the the % character is deleted.

This is being run in the native Terminal.app with no special plugins or SIMBL tweaks or anything like that, and I have reproduced this bug on both a 2011 iMac and a 2011 MacBook Pro, both running 10.7.4

signal.cpp's default_handler gets an event_t by value, which looks highly suspicious, since an event_t contains non-PODs like wcstrings.

I just found out fishfish supports ⌥→ and ⌥← for jumping a word at a time (which is totally awesome!), would it make sense to support ⌘→ and ⌘← to jump to the beginning and end of the current line? I know you can use ^a and ^e but I use ⌘→ and ⌘← all the time and it feels a lot better to me.

On DragonFly BSD, gnu make is 'gmake'. That's not the bug; I'm explaining why I typed what I did.

This error may apply to other non-OS X BSD systems too.

gmake: *_\* [fish] Error 1

If you mistype a command, we'll happily suggest it again, even if the command failed to run. We ought to feed command success or failure back into history so it won't autosuggest that. But we need a way to distinguish between commands that could not run and commands that ran successfully, yet indicated failure to communicate some other information (such as grep's "not found").

alias foo="cd ~/"
batman@batman ~/D/S/rails> alias foo="cd ~/"
fish: Could not expand string '$tmp[2]'
/usr/local/share/fish/functions/alias.fish (line 19): set body $tmp[2]

The sed expression looks busted.

Whenever the ~ character is typed:

niemeyer@gopher ~> fish
niemeyer@gopher ~> ~fish: Job 1, 'fish' terminated by signal SIGSEGV (Address boundary error)

Currently fish's python scripts fail on systems where 'python' invokes Python3, like Arch Linux.

On these systems, we can get by with '#!/usr/bin/env python2' but that fails on OS X (which has no python2 symlink).

This bug tracks finding a resolution.
