fish on raspberry pi

When I get my hands on a Raspberry Pi I will, of course, want to install 
fish in an Ubuntu environment. Can anyone foresee any problems with 
using the existing Ubuntu fish package on ARM based architecture?

errors when doing cd -

When I run `cd -` I get this output every time (but the command does 
work). I'm compiled and installed from the gitorious master a couple of 
days ago, OS X lion.

I'm only running the command once but the output seems to be duplicated.

$ cd -

/usr/local/share/fish/functions/prevd.fish (line 16): switch $argv[$i]

Why bash is broken

I just found this post written by Axel while looking for something else and thought that it would be good to share (apologies if you've seen it already).

Error, am I compiling the right version

Hi

I've got a new machine and need to install fish. I've downloaded the 
current master branch from gitorious but am getting this error when I 
run make

...
gcc -g -O2 -std=c99 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 
-fno-optimize-sibling-calls -Wall 
-DLOCALEDIR=\"/usr/local/share/locale\" -DPREFIX=L\"/usr/local\" 
-DDATADIR=L\"/usr/local/share\" -DSYSCONFDIR=L\"/usr/local/etc\" 
-std=c99 -c -o common.o common.c
In file included from common.c:86:
util.c: In function ‘q_realloc’:
util.c:131: error: ‘ptrdiff_t’ undeclared (first use in this function)
util.c:131: error: (Each undeclared identifier is reported only once

util.c:131: error: expected ‘;’ before ‘diff’
util.c:144: error: ‘diff’ undeclared (first use in this function)

Is master the correct version to use?

Thanks

Re: commandline function and escaping

I agree that 'commandline -b' indeed has a less-than-optimal behaviour. We could add a switch to tell it not to interpret escape characters, but I really can't think of a use for the current behaviour either, so I agree that it should just be fixed. I committed a fix to my personal branch on gitorious to test if it works.

Hi,

I have a function which puts current commandline buffer to the editor.
It's really useful sometimes.

function .edit_cmd --description 'Edit cmdline in editor'

set -l p (commandline -C)
commandline -b > $f
vim -c set\ ft=fish $f
commandline -r (more $f)
commandline -C $p
rm $f
end

Recently, I've found that it breaks the quoted text. I.e. the command
'echo "first second" third' is looses its double quotes when editing.
Unescaping is done in file builtin_commandline.c:199. I wonder if
unescaping is really needed when cmd is not tokenized. I simply can not
figure
out any possible usage of it.

So I propose to avoid unescape function when commandline is called without
'tokenize' key.

What do you think about it?

Maxim

please help: GNU Fish, key bindings---sorry to disturb you!

I am new to Fish and have some problems adding some features to it. I am
sorry to mail you knowing you are, in fact, not in the responsibility
for technical support, but your email address is the only one I could
find in fish's documentation. I wanted to do something like this: while
pressed Alt(\e)+p, fish adds a "|less" under the cursor in the command
line. So I wanted to bind Alt(\e)+g to something like "|grep", but the
command: bind \eg "\|grep" or anything I could think of did not work.
Wish you could spare a time for it, please!

stderr in red

Hi, saw this on hacker news tonight, and wondered if an option to print stderr 
in red could be added to fish?

   https://github.com/sickill/stderred
   http://news.ycombinator.com/item?id=3349562

Looks like it could be a user friendly addition.

[Bug]Cannot read STDIN when calling from function with paramaters

Hello everybody,

I have a slight problem, that this simple function can illustrate:

function writeIt
set out /tmp/out.txt
cat - > $out
end

If the function is called in the shell, one cannot see the input, however
>cat /tmp/out.txt
outputs whatever one has input.

If the function is added to ~/config/fish/config.fish and called with
>fish -c "writeIt"
one can see their input, while typing.

Could someone look into this please ?

Regards,
DeathGorePain

binding

Hi,

is it possible to bind special keys with ctrl and shift modifiers? Like 
CtrlEnter, ShiftEnter and so on.
\c\n doesn't help.

best regards,
Maxim

In such case just edit the file /usr/share/fish/functions/help.fish (or better copy it first to ~/.config/fish/functions/ and edit there), there is no need to use funced.

that's what I usually do. I just though that probably I'm missing something.

A bigger terminal? :)
