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.
Fixes#3129
Doesn't colorize if output is redirected.
This is "fun" and indenting happens to make most of the included
functions display more narrow and fit better into a terminal window.

The previous commit to add a `--with-timestamp` flag to the `history` command
caused me to notice the history function didn't recognize the new long option.
Neither did it recognize the short options for the builtin command. This
change fixes both of those issues.

1. It is possible to add multiple whitespace characters between the keyword (i.e. Host) and the argument(s).
2. It is allowed to have a single = and whitespace between the keyword and the argument(s).
3. It is possible to add multiple host names under a single Host directive by spacing the names apart.
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.

We only use the short sha for figuring out whether the state is

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
indicate you know what you're doing.

I'm going to modify these functions as part of dealing with issue #3000

This makes it easy for the user to request floating point output with the
desired number of digits after the decimal point (not to be confused with
significant digits).
Note that this is just a thin wrapper so someone can say `math -s3 10 / 3`
rather than `math "scale=3; 10 /3"`.

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 upshot was that standout (i.e., reversing fg/bg colors) mode should be used until themes are agumented with proper support for background colors and special characters.

This ensures they can just be called and "the right thing" will happen -
fish_user_key_bindings will be executed, the variable will reflect the bindings.

Commit c0e8ad6 on 2015-10-02 to "Make vi bindings inherit the defaults"
inadvertently reverted commit b6b6de3. Fix that regression. And while I
hate to make "git blame" say I changed the entire file make the function
adhere to fish_indent style.
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.
