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!

You have to define a function like __fish_grep, similar to
__fish_paginate in /usr/share/fish/functions/__fish_paginate.fish and
bind it to Alt-G like this:
bind \eg '__fish_grep'

Rather
bind \eg "commandline -a '|grep'"

commandline function and escaping

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 f (mktemp)
                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?

regards,
Maxim

Yes, I also thought about this key. And decided that it is not really  
needed.
Indeed one can use 'echo (commandline -b)' to unescape cmd.

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: for each function it appears in.)
util.c:131: error: expected ‘;’ before ‘diff’
util.c:144: error: ‘diff’ undeclared (first use in this function)
make: *** [common.o] Error 1

Is master the correct version to use?

Thanks

I have just successfully compiled the following clone on archlinux
using gcc 4.6.2:
git://gitorious.org/fish-shell/fish-shell.git
I guess that is the master.
