1. When run with no arguments, make abbr do the equivalent
of `abbr --show`
2. Enable "implicit add", e.g. `abbr gco git checkout`
3. Teach `abbr --show` to not use quotes for simple cases
4. Teach abbr to output -- when the abbreviation has
leading dashes
Add some basic tests to abbr too.
Add a new function fish_mode_prompt which (if it is defined) has its output
prepended to the left prompt. Rather than replacing the prompt wholesale, make
fish_vi_mode enable this function by setting a variable __fish_vi_mode. This
enables vi mode to interoperate nicely with custom prompts. Users who want
to change how the mode is reported can either redefine this function or
erase it entirely. Fixes#1988.
Prior to this fix, if you exported a variable in one scope
and then unexported it in the next, it would remain exported.
Example:
set -gx VAR 1
function foo; set -l VAR; env; end
foo
Here 'VAR' would be exported to 'env' because we failed to
notice that the env var is shadowed by an unexported variable.
This occurred at env var computation time, not in env_set!
Fixes#2132
- Add four new functions: forward-bigword, backward-bigword,
kill-bigword, backward-kill-bigword
- Add new enum move_word_style_whitespace and related state machine
method
- Change vi key bindings to operate on bigwords: B, gE, W, E, dW, diW,
daW, dE, dB, dgE, cW, ciW, caW, cE, cB, cgE, yW, yiW, yaW, yE, yB,
ygE
su does not reset XDG_RUNTIME_DIR, which means that XDG_RUNTIME_DIR
may point to directories that the user does not have permission
to access. Similarly there is no guarantee that XDG_RUNTIME_DIR
points to a directory that actually exists. Rather than try to
handle these issues, we simply ignore them, effectively disabling
realtime uvar notifications. Fixes#1955.

Notification is sent using an OSC 777 escape sequence as described at
http://known.phyks.me/2014/local-notifications-for-weechat-and-urxvt.
The specific notification is crafted to match that emitted by bash
when running under Fedora 22 with the "vte-profile" RPM installed.
See the code for "__vte_prompt_command" starting at
http://pkgs.fedoraproject.org/cgit/vte291.git/tree/vte291-command-notify.patch#n307
to see exactly what bash produces. My approach is, however, a bit
more paranoid about control characters embedded in commands.
Gnome-terminal 3.16 responds to this escape sequence by posting a
desktop notification if the containing terminal window does not have
focus. This lets the user know that a long-running background command
has completed. Job notification is promoted as a Fedora 22 feature
(http://fedoramagazine.org/terminal-job-notifications-in-fedora-22-workstation/),
so it would be good for fish users to be benefit from it.
Conversely, anyone who does not want this feature can use "functions
--erase __notify_vte_command_completed" to turn it off.
Before this fix, `function -a arg1 name1` would produce a
function named 'arg1'. After this fix, it will produce a
function named 'name'. See #2068 for more.
When declaring a function using the function "function", the options must follow, not precede, the function name.
The examples demonstrate this syntax, but the synopsis previously showed the options preceding the name.
In FAQ:
> I'm seeing weird output before each prompt when using screen. What's wrong?
The command provided is
echo 'function fish_title;end' > ~/.config/fish/config.fish
Using `>` will overwrite current config.fish.
We should use `>>` instead.
