ncurses since 6.0 sends the "E3" sequence along with "clear", even for
just `clear` or `tput clear`. This deletes the scrollback buffer which
is usually not what you want.
Fixes#2855.
Before this change the function `__fish_print_filesystems` would print
an error message about an empty wildcard match for the pattern
`$PATH/mount.*`, if the current operating system does not include any
helper binaries for the command `mount`. An example for such an OS is
the current version of macOS (version 10.12).
Change the escape key binding in insert mode (in vi key bindings)
to check if we are in paging mode. If so, emit cancel and stay in
insert mode. Otherwise perform the current behavior of switching
back to default mode and adjusting the cursor.
Fixes#2871
This commit addresses many of the style problems with the previous
commit. If this introduces any bugs they are solely my fault. The style
of this code needs more improvement. Some of which could be done today.
Others will have to wait until `fish_indent` is improved.
Add IPV6 /etc/hosts completion support. Parses columns rather than values which produces improved output.
Support ssh -F and Include completion
Ignore ssh Hostname and Host with wildcard. The following only get in the way:
- Hostname: Host resolves to Hostname
- Wildcard Host: Cannot ssh to a glob pattern
Improve scp completions
* complete only local files when no host provided
* complete only remote files when host is provided
* complete local files or hosts when no separator
Disable username completion for ssh/scp
Username completion only provides local users which will unlikely be
useful on a remote machine. ssh will use the current username (the only
useful one) or one provided in the ssh config.
* Added new function for the default prompt mode
Now fish mode prompt will call fish_default_mode_prompt, this will solve #3641
* Added function description
* Change wording for documentation about default mode prompt
* Finish changes requested in code review
This would fail on very long numbers, e.g.
`math "1 + 1233242342353453463458972349873489273984873289472914712894791824712941"`
would now return "42", where it previously returned the correct "1233242342353453463458972349873489273984873289472914712894791824712942".
This reverts commit 26e781ef5a.
It's not the case that macOS and old BC doesn't respect this environment
variable, just that they don't have special behavior when it's set to 0.
However, there is rather universal favorable behavior with a value of 2.
Output is of the form:
\
999999999999999999999999999999999...
with the second line being arbitrarily long. So just grab that line
instead of stitching with `string`.
This can yield a 25-30% speedup.
This commit adds a feature that after typing "git add" and pressing
"alt+h", the manpage for "git-add" instead of "git" would be displayed.
The new logic takes the first argument which doesn't start with a dash
and tries to display manpage for "command-argument"; it falls back to
"man command" it the first try doesn't succeed.
Fixes#3618.
- Support completing dynamic make targets.
- Support completing make targets when using -C/--directory.
- Support `-Cdir/path`, `-C dir/path`
- Support `--directory=dir/path`, `--directory dir/path`
This detects if the make command have the `-p` switch otherwise it
assumes it is BSD make and will run a different command to try to figure
out the available targets.
The recent refactoring to separate default (emacs) from vi key bindings
overlooked adding `\cH` bindings to vi mode. This also fixes the
behavior of the [del] key bindings (\x7F).

This implements a standard function and bindings for editing the command
line in an external editor. This feature has been requested multiple

I had disabled having `make style-all` restyling fish scripts because a
majority of them did not conform to the style enforced by `fish_indent`.
I recently restyled most of the fish scripts with the exception of the
completion scripts. So this re-enables restyling all scripts with the
exception of completion scripts.
The abbr function doesn't have the possiblity to rename abbreviations.
You have to delete the old one and create a new one. This commit adds
this functionality and uses the syntax:
abbr -r OLD_KEY NEW_KEY
Fixes#2155.
I hate doing this but I am tired of touching a fish script as part of
some change and having `make style` radically change it. Which makes
editing fish scripts more painful than it needs to be. It is time to do
a wholesale reformatting of these scripts to conform to the documented
style as implemented by the `fish_indent` program.
This augments the previous change for issue #3346 by adding an error
message when an invalid integer is seen. This change is likely to be
controversial so I'm not going to squash it into the previous change.
We cannot just use TERM = xterm and defined Ss sequence, as some old
vte-based terminals are still in the wild that don't support the
sequence and don't have $VTE_VERSION set.
I have tested this on
- konsole - supported and works ($KONSOLE_PROFILE_NAME)
- new xterm - supported and works ($XTERM_VERSION)
- lxterminal-gtk3 - supported and works ($VTE_VERSION)
- new gnome-terminal - supported and works ($VTE_VERSION)
- lxterminal-gtk2 - not supported and deactivated (no $VTE_VERSION)
- tmux in konsole - works
- tmux in lxterminal-gtk2 - deactivated
and for all supported ones with the respective variable erased, to see
that it is deactivated.
Fixes#3499.
The changes related to issue #3068 removed most of the emacs bindings
from vi mode. However, since fish 2.4.0 was released several people have
pointed out that the directions for reinstating the legacy hybrid key
bindings don't work. This change fixes that and makes it easier to use
the legacy hybrid bindings.
Fixes#3556
While working on making the history command support case-sensitive and
insensitive searches I noticed that entering "all" when interactively
deleting history entries resulted in an error. That's because the
history builtin currently only supports `--exact` so we need to loop
over the matching entries and delete them one at a time.
Fixes#3448
My previous change to avoid creating a *.pyc file when running
create_manpage_completions.py was wrong because I put the
`sys.dont_write_bytecode = True` on the wrong line. Rather than simply
move that statement make the simpler, cleaner, fix that removes the need
for `eval` where that program is invoked.
After implementing `builtin fish_realpath` it was noticed that it did
not behave like GNU `realpath` without options. Which is super annoying
since that was the whole point of implementing the command. Major
failure on my part since I wrote the unit tests to match the behavior of
the existing `wrealpath()` function that I simply exposed as a builtin
command. Rather than actually verifying it behaved in a manner
compatible with GNU realpath.
Also, while the decision to call the builtin `fish_realpath` seemed to
make sense at the time of the original commit further reflection has
shown that to be a silly, idiosyncratic, thing to have done. So rename
it to simply `realpath`.
Fixes 3400
This adds a flag to the `history search` command to limit the number of
matching entries to the first "n". The default is unlimited. This is
mostly useful in conjunction with aliases (i.e., functions) that are
intended to report the "n" most recent matching history entries without
piping the result through the user's pager.
Fixes#3244
Don't wrap fish_indent at all if the version in $PATH matches
$FISH_VERSION.
When we do wrap it, resolve the path once, and use that via alias
machinery instead of doing an eval each time.
In both cases, `type fish_indent` can tell us what it's actually going
to do now.
clarity aside, it's faster if we only eval the one time.
eval is not only evil, but slow.
> for h in $history[1..100]; echo $h | fish_indent --no-indent; end
before: CMD_DURATION = 1005
if fish_indent is kosher in PATH: 549
if not, using alias: 687
these modern terminals both compose a nicer title if we don't try to provide a custom one (no path in title twice, "fish" in title twice) - and the user can configure which components they'd like in their terminal inside the terminal preferences.
Also make test "$VTE_VERSION" -ge .. work once I commit `test` strtoi

works even if it's empty.
Fixes#107
This deprecates the use of long options for history sub-commands (e.g.,
`history --delete`) in favor of proper sub-commands (e.g., `history
delete`). It also eliminates the short options for those sub-commands.
Also change option processing to allow options anywhere on the command
line to match how the vast majority of fish builtins handle flags.
Replace --with-time with --show-time.

* Use 'grealpath' if installed for realpath fallback

This has the same name and path as ubuntu's, but takes less arguments.
So we need to actually find if the distro thinks it is suse, and then
use it.
Fixes#3366.
Adds a color reset thing, to ensure fish tries to use hard colors during
testing.
Also, work on a discrepancy (not introduced by my changes, afaik) when
with some combinations of color settings, and usage of --bold, caused super
flakey color paninting in the pager. Downwards movements that trigger
scrolling vs. upwards movement in the pager would only apply bold to
selections when moving upwards. The bold state of the command completions in
the pager was flipping flops on and off, depending on if there is a description
on the preceding line.
Implement a lame fix by reseting the color to normal and applying a
different style on the rightmost ')' which seems to be what was influencing it.
Makes fish use terminfo for coloring the newline glich char.
The previous solution would not erase the previous bindings if
fish_vi_key_bindings was called with a mode argument. So if the user
switched to vi with a different initial mode, they'd keep their previous
bindings also.
Supersedes e89057b.
Some of these were defined in the shared bindings, some (like \cy yank)
were just literally duplicate in the same files.
This should _not_ change anything. In particular this does not remove
hardcoding of sequences (because terminfo might be wrong or the term
might need smkx).
Found with
```
function bind
set -l binds (builtin bind)
builtin bind $argv
set -l newbinds (builtin bind)
if set -q argv[1]; and not test "$argv[1]" = "--erase"
if test "$binds" = "$newbinds"
echo "Duplicate: " (string escape -- $argv)
end
end
end
```
The vi-bindings function would unconditionally erase all bindings,
making it impossible to call it last. This would disable the
mode-indicator (and in future also the cursor).
Make it so any argument to fish_vi_key_bindings stops it from erasing
bindings.
It would also be possible to demand an argument to erase (or to erase as
a separate step). but the usual case seems to be _switching_ to a set of bindings.
This didn't work on platforms where tput exists but can never accept
terminfo names. This includes the current versions of FreeBSD - it
used to do both, now it doesn't. So, fall back to the old termcap names
by (tput smso; or tput so). Add check for the tput program before we
even try.
The extra things `eval` does are all for code that runs
interactively. Because we just define a function, we don't need it.
This improves alias' performance by about 20-25% (0.783608s to 0.585585s
on about 500 aliases) and avoids triggering #3345.
Implementing the --shadow-builtin flag has proven to be highly controversial.
Revert the introduction of that flag to the `function` command. If someone
shoots themselves in the foot by redefining a builtin as a function that's
their problem and not our responsibility to protect them from doing so.
Fixes#3319
It's not ideal since we can't get the real result so we just assume it's
"0". That triggers the easier path, which still might display the wrong
thing, but we have to pick something.
Possible fix for #3321.
The recent change to reconcile the history builtin command and function
broke an undocumented behavior of `history --delete`. This change
reinstates that behavior. It also adds an explicit `--exact` search mode
for the `--search` and `--delete` subcommands.
Fixes#3270
Only on the OS X travis build.
I can't reproduce it but I figure it's something to do
with test -e vs test -x or the echo -n in command substitution.
Oops.
This was erroneously omitted from the previous commit.
Now backspace in insert mode does backward-delete-char, in default mode
backward-char (i.e. no deleting, just moving). This is consistent with vim.
This undoes the inheritance since it shared too much.
The idea here is to share bindings that aren't something the editors we're inspired by do - there's no "execute" in vi.
The basic editing and moving bindings are now vi-style in vi-mode and emacs-style in default mode.
Only one file belonging to fish-shell had DOS/bogus line endings,
with `git add' picking up changes after updating .gitattributes:
hostname.fish.
Unsurprisingly, it has code to support cygwin and was likely
worked on by a user on a Windows machine. This will help
such cases in the future.
Also, in pcre2-10.21/, there was RunTest.bat which was (correctly)
CRLF formatted. We don't use this batch script at all, so rather
than LF it or add an exception, blast it away like the other pcre2
files omitted from the repo.
A common problem for users is that fish doesn't get a locale. This often
happens if systemd is used with getty and fish as login shell.
Fixes#277
Note that I (@krader) made editorial changes before merging this. For
example, running `make style` and otherwise changing long statements to a
series of shorter statements. So if there are any problems it is possible
I introduced them.
Fish assumed that it could use tparm to emit escapes to set colors
as long as the color was under 16 or max_colors from terminfo was 256::
if (idx < 16 || term256_support_is_native()) {
// Use tparm to emit color escape
writembs(tparm(todo, idx);
If a terminal has max_colors = 8, here is what happenened, except
inside fish:
> env TERM=xterm tput setaf 7 | xxd
00000000: 1b5b 3337 6d .[37m
> env TERM=xterm tput setaf 9 | xxd
00000000: 1b5b 3338 6d .[39m
The first escape is good, that second escape is not valid.
Bright colors should start at \e[90m:
> env TERM=xterm-16color tput setaf 9 | xxd
00000000: 1b5b 3931 6d .[91m
This is what caused "white" not to work in #3176 in Terminal.app, and
obviously isn't good for real low-color terminals either.
So we replace the term256_support_is_native(), which just checked if
max_colors is 256 or not, with a function that takes an argument and
checks terminfo for that to see if tparm can handle it. We only use this
test, because otherwise, tparm should be expected to output garbage:
/// Returns true if we think tparm can handle outputting a color index
static bool term_supports_color_natively(unsigned int c) { return max_colors >= c; }
...
if (term_supports_color_natively(idx) {
And if terminfo can't do it, the "forced" escapes no longer use the fancy
format when handling colors under 16, as this is not going to be compatible with
low color terminals. The code before used:
else {
char buff[16] = "";
snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);
I added an intermediate format for colors 0-15:
else {
// We are attempting to bypass the term here. Generate the ANSI escape sequence ourself.
char buff[16] = "";
if (idx < 16) {
snprintf(buff, sizeof buff, "\x1b[%dm", ((idx > 7) ? 82 : 30) + idx + !is_fg * 10);
} else {
snprintf(buff, sizeof buff, "\x1b[%d;5;%dm", is_fg ? 38 : 48, idx);
}
Restores harmony to white, brwhite, brblack, black color names.
We don't want "white" to refer to color color #16, but to the
standard color #8. #16 is "brwhite".

This fixes several problems with how the builtin `history` command handles
arguments. It now complains and refuses to do anything if the user specifies
incompatible actions (e.g., `--search` and `--clear`). It also fixes a
regression introduced by previous changes with regard to invocations that
don't explicitly specify `--search` or a search term.
Enhances the history man page to clarify the behavior of various options.
This change is already far larger than I like so unit tests will be added
in a separate commit.
Fixes#3224.
Note: This fixes only a couple problems with the interactive `history
--delete` command in the `history` function. The main problem will be
dealt with via issue #31.
We don't seem to mention in the documentation that we were forcing
-t for all interactive uses. If we want to do that we should apply
that in the builtin.
history.fish reimplementing every option and doing things kind of
differently is a real pain and it's not clear if the docs are
referring to the or the wrapper script or both.
Someone running fish in an unusual locale reported that an `assert()` was
firing when they typed `pkill c`. I traced it to two bugs. First, the
__fish_make_completion_signals command was producing a weird result. Second,
the builtin `complete` command wasn't adequately verifying its arguments.

1. and 3. are actual conventions that we use in our team, and I couldn't get auto-complete working for fish without this modification.
Modification explained:
a. The space between Host(?:name)? and the \w.* was replaced by (?:\s+|\s*=\s*) to match any sequence of whitespace characters, or optional whitespaces with a single =, per spec.
b. Result of first replacement is piped through another string replace to switch duplicate whitespace characters to a single space, and then piped to be split by that space. This allows specifying several aliases or host names in a single Host/Hostname definition, also per spec.

It's currently too easy for someone to bork their shell by doing something
like `function test; return 0; end`. That's obviously a silly, contrived,
example but the point is that novice users who learn about functions are
prone to do something like that without realizing it will bork the shell. Even
expert users who know about the `test` builtin might forget that, say, `pwd`
is a builtin.
This change adds a `--shadow-builtin` flag that must be specified to

There was an extended discussion in https://github.com/fish-shell/fish-shell/issues/2904 about using a bright yellow background to make the cancelled command indicator, ^C, standout.

The existing implementation grows the $dirprev array without bounds. Besides
causing what would appear to be a memory leak it also makes the nextd and
prevd commands more expensive than they need to be. It also makes it harder to
create a useful "menu" cd command.
In addition to implementing a reasonable limit on the size of the $dirprev
array I've reformatted the code using fish_indent.
Update the documentation to include mentions of the $dirprev and $dirnext
variables as well as the limit on how much directory history is kept.

Fixes the invocation of a user-specified browser by the `help` command on Cygwin.
- Use `cygstart` to launch the browser with escaped quotes to avoid problems with spaces in the path to the browser, (e.g. Program Files).
- Use `cygpath` to convert the base help dir to a Windows path before constructing the fie URL to pass to the browser.
This changes the default escape timeout for the default keybindings (emacs
mode) to 300ms and the default for vi keybindings to 10ms.
I couldn't resist fixing a few nits in the fish_vi_key_bindings.fish file
since I was touching it to set the escape timeout.
It used to be that way and we recommend `set fish_greeting` (i.e. set to
empty) in the docs - possibly since we check if the variable is defined
on upgrade.
This fails on e.g. an abbr that uses `env a=b`, like the included test demonstrates.
Unfortunately it decreases the speed again (2s vs 2.2s vs 4s original),
but correctness is more important.
- Replace __fish_abbr_escape with `string escape`
- Don't double-parse the key
- Replace IFS magic with string
Together, this seems to speed it up by a factor of about 2.
Unfortunately, nvim will, even when running in a terminal that supports
it, swallow the sequences whole, rendering the displayed text _white_.
This means falling back to 256 colors is the lesser evil as at least a
blue-ish color will display as blue while a red-ish will be red, instead
of both showing white.
nvim's behavior does _not_ change depending on
$NVIM_TUI_ENABLE_TRUE_COLOR or any other option I could find and neovim-qt
exhibits the same behavior.

https://github.com/NixOS/nixpkgs/pull/12000, but prior versions of the
hook ignore anything but the first argument anyway, so this is
backwards-compatible.
This skips the weird dance where we'd define a simple handler and then
later overwrite with a fancier one, once the first event came in.
It turns out that isn't necessary, as it doesn't actually improve
startup speed because the checks needed to define fancier handlers are fast.
In case we are non-interactive, still define the simple handler, and
keep the default handler for users to switch to.
Unfortunately, there's no standard way to detect support (importantly,
terminfo doesn't encode it), but there's a variety of terminals that
support it that we can detect.
It's better than letting this functionality go to waste.
Check KONSOLE_PROFILE_NAME instead of DBUS_SESSION because Konsole can be compiled without dbus support.
Check ITERM_SESSION_ID's format for 24bit support
This has changed since the last release, just like 24bit support. So if
we check one, we get the other.
Allows the length of each shortened path component to be customized by setting the `fish_prompt_pwd_dir_length` variable to the number of characters to include (plus a leading dot because that's special). Maintains the default behavior of shortening path components to just one character. You can also set `fish_prompt_pwd_dir_length` to an empty or invalid value or 0 to disable shortening completely.
This reduces code duplication and adds some previously unavailable
bindings that don't quite _violate_ the vi-principle (like
prevd-or-backward-word on alt-left) and matches other "impure" bindings
like \cf for forward-word (a quite emacs-ish binding) we already have.

For cygwin, you can't `cd C:`, so a prompt of "C:/Something" is
misleading.
For OSX, we dereference symlinks elsewhere
This also simplifies prompt_pwd quite a bit.
This is to the benefit of systems with ancient GNU sed, which does not
recognize "-E", but only "-r".
Fixes#2305 - even if it doesn't replace all `sed -E` invocations in the
codebase, the others are unlikely to occur on CentOS and other similarly
crusty systems.
`sort -u | uniq` is completely redundant, calling grep for every
status-pair is unnecessary, `contains` doesn't take the word "in" as
special.
None of these are critical and there's basically no performance benefit
since this function is utterly dominated by hg calls.
This doesn't add anything except slowing the function down by about
33%. Checking for a branch is just as good and that is displayed in the
prompt anyway.
This is used in at least 4 places, all of which have a bug in that they
print "options" as a valid repo. It seems better to fix it once,
especially given that there are tons of AUR helpers and pacman wrappers,
all of which might need this info.
net_tools, which provides `ifconfig` and `netstat`, among other things,
has last been updated in 2013. This means `ifconfig` on linux is
basically dead.
Instead of ifconfig, use `ip` (from iproute2), which is much more powerful and
provides a much more annoying commandline syntax.
Instead of netstat, just look at /sys/class/net.
fish_user_key_bindings is the user's, and they should know if they want
vi-ish bindings or emacs-ish (or nano-ish). If they want to define
multiple, they can also do that (e.g. via checking what
$fish_key_bindings is set to).

See #1925: This allows users to disable the cnf-logic which can be quite
slow on small hardware (like a raspberry pi).

Erase startup cnf-handler early
Simplifies the code a bit - in particular it removes the special-casing
from the startup handler.

Make overriding cnf-handler work
Do this by renaming the __fish_command_not_found_handler used during
startup to __fish_startup_command_not_found_handler. That allows us to
check if __fish_command_not_found_handler has been defined and skip the
setup of the normal one.
Now disabling cnf-handling can be done via defining an empty
__fish_command_not_found_handler in config.fish
This adds a special colorscheme and prompt function guaranteed to work
on a VT and activates them automatically if $TERM = "linux".
set_color is overridden to only allow the 8 colors VTs have (under the
assumption those are always the same) and the color variables are
shadowed with global ones so they don't pollute our nice capable terms.
This used to be a function because we didn't have complete -w
Use that and it becomes a bit simpler.
This also simplifies the code in a few other ways (like removing a
useless-use-of-cat)
and adds comments about a few edgecases.
changed `function __trap_handler_EXIT --on-exit %self` to `function __trap_handler_EXIT --on-process-exit %self`
I'm guessing the on-exit syntax was from an older version? Trapping EXIT with that syntax caused errors.
The following behaviour is added:
- an empty pushd exchanges the top two directories in the stack;
- pushd +<n> rotates the stack so that the n-th directory (counting from the left of the list shown by dirs, starting with zero) is at the top;
- pushd -<n> rotates the stack so that the nth directory (counting from the right of the list shown by dirs, starting with zero) is at the top.
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.
- 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
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.
With the fix for #365, fish_command_not_found event handlers
receive the command and all of its arguments. But commands
like /usr/lib/command-not-found expect only the command name.
So when invoking an external command, just pass the command
name, not all of the arguments.
In 73f344f41b, we allowed autoloaded functions to be deleted.
For some reason, funcsave immediately deletes the function it
creates. This previously did very little, since the function would
immediately be re-autoloaded, but with the fix for 73f344f41b
the function gets tombstoned. So the effect is that funcsave
makes the function disappear! This simply removes the erase call,
which dates back to fish 1.x.
It seems that `ul` can't handle the escape sequences for bold text that `nroff` generates on my system. Fixed by either removing `| ul`, or adding `-c` to the `nroff` command.
Needs testing for old (OSX?) versions of nroff.
Support for space-delimited abbreviations was added to the expansion
parser in fbade198; this commit extends that support to the user-facing
tools, and documents the space-separated behaviour. Equals-delimited
abbreviations are expected to be removed before the next release.
Work on #731.
There is no CTRL-C handler for the default mode in the vi bindings. This makes it difficult to say "never mind" and start a new command line like you can do in bash's vi mode.
There were CTRL-C handlers for insert and visual modes that go back to default mode, but nothing happens in default mode. I copy-pasted the CTRL-C handler from the default key bindings file.
(Ideally, the behaviour of git could be implemented: pipe the input
through a pager iff the length is > window size and in interactive
mode).
Closes#1076.
The terminal width magic that __fish_print_help learned doesn't help
when builtin_print_help runs it in a subshell. Instead, add an
undocumented --tty-width flag to __fish_print_help that's used to pass
the terminal width.
As a result of this rewrite, the output now:
* Expands to fit the terminal width, like `man` does
* Preprocesses the manpage with `tbl` just in case, since `man` does
this, even though I doubt any fish manpages use `tbl` formatting.
* Handle bold/underline with the `ul` command as it was designed for
instead of trying to fake it with `sed`.
* Compresses blank lines as `man` does with the default `less -is`
pager.
