Users continue to be surprised that fish auto splits/joins three env
vars but not other similar vars. Mention this in the tutorial to make it
less likely new users are surprised by this behavior.
Fixes#4009
It still performs the assignment even if the command substitution
returned unsuccessfully - `set foo (echo bar; false)` returns 1 but
sets $foo to bar.
Also use `type -p` instead of `which`.
Another change related to issue #3985. I forgot to includes this in my
previous two changes related to to consistently returning status 121
when any command, not just `string`, is handed invalid args.
This primarily replaces "STATUS_BUILTIN_OK" with "STATUS_CMD_OK" and
"STATUS_BUILTIN_ERROR" with "STATUS_CMD_ERROR". That is because we want
to make it clear these status codes are applicable to fish functions as
well as builtins. Future changes will make it easier to use these
symbols and values in functions.
Per discussion in PR#3998 to review adding a `--filter` flag to `string
replace` rename the same flag in the `string match` subcommand to avoid
confusion about the meaning of the flag.
Discussion in issue #3295 resulted in a decisions to rename the
functions --metadata flag to --details.
This also fixes a bug in the definition of the short flags for the
`functions` command. The `-e` flag does not take an argument and
therefore should not be defined as `e:`. Notice that the long form,
`--erase`, specifies `no_argument`. This discrepency happened to work
due to a quirk of how the flag parsing loop was written.
This is the first step in addressing issue #3965. It renames some of the
functions involved in validating variable and function names to clarify
their purpose. It also augments the documentation to make the rules for
such identifiers clearly documented.
- Error out if anything that is not a PID is given
- Otherwise background all matching existing jobs, even if not all
PIDs exist (but print a message for the non-existing ones)
Fixes#3909.
This puts a hard upper bound of 10 MiB on the amount of data that read
will consume. This is to avoid having the shell consume an unreasonable
amount of memory, possibly causing the system to enter a OOM condition,
if the user does something non-sensical.
Fixes#3712
This implements a way to use the `functions` command to perform
introspection to learn about the characteristics of a function. Such as
where it came from.
Fixes#3295
If the kernel reports a size of zero for the rows or columns (i.e., what
`stty -a` reports) fall back to the `COLUMNS` and `LINES` variables. If
the resulting values are not reasonable fallback to using 80x24.
Fixes#3740
* 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
Another dev pointed out my previous attempt to resolve issue #3612 did
not do a good job of clarifying the matter. Hopefully this change is
better at explaining why autoloading is not applicable to aliases.
* Add italics and dim modifier to set_color
* update documentation for set_color
* add reverse mode to set_color
* Use standout mode as fallback for reverse mode
* Apply patch from @Darkshadow2 adding additional modes
Trailing whitespace on a `\fish` command was causing this build failure:
/private/var/folders/T/fish_doc_build_3RT8yS/random.doxygen:44:
warning: found </pre> tag without matching <pre>
This implements a standard function and bindings for editing the command
line in an external editor. This feature has been requested multiple
times in the past year with various solutions cut and pasted into those
issues. This change combines the best aspects of those solutions.
Fixes#1215
This commit fixes a bug which causes that
fish -c ')'; echo $status
("Illegal command name" error) returns 0. This is inconsistent with
e.g. when trying to run non-existent command:
fish -c 'invalid-command'; echo $status
("Unknown command" error) which correctly returns 127.
A new status code,
STATUS_ILLEGAL_CMD = 123
is introduced - which is returned whenever the 'Illegal command name *'
message is printed.
This commit also adds a test which checks if valid commands return 0,
while commands with illegal name return status code 123.
Fixes#3606.
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.
Some key bindings were updated in fish 2.4.0 but in some cases the
documentation does not correctly reflect the actual behavior. This
commit attempts to fix that.
The `status` command currently silently allows incompatible flags (i.e.,
subcommands). Too, using flags to specify subcommands misleads the user
into thinking they can specify multiple subcommands.
We recently modified the `history` command to deprecate using flags for
subcommands. This change does the same for the `status` command.
Fixes#3509
People regularly ask how to make abbreviations global (i.e., private to
a fish session) rather than universal. So explain how to do so in the
`abbr` man page.
Fixes#3446
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
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.
Fixes#3367
Update history docs.
Note - the omission of a mention of timezone was intentional. These were recorded as naive timestamps lacking timezone information in the first place.
Improves the grouping of multiline history entries
by sepearating the timestamps and history entires onto seperate lines.
Use wcsftime() Saves us a conversion, might as well.
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.
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.
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
Fixes fish-shell/fish-site/issues/34.
These make the inline commands illegible on Android Chrome:
respectively, overlapped with other text, and smaller than the body
text.
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
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.
Update docs for "brblack", "brwhite" existing.
We no longer mention colors like grey, brown and purple, which are aliases
for yellow, magenta, white/black. The color names still work but there
isn't a good argument for there being two ways to do that: especially in
the age of 24-bit terminals where one might expect yellow and brown or
magenta and purple to actually be different colors.
Copyedit rest of document for inaccuracies, strange advice, brevity (a lot
of "you" pronouns, for example.)
Document the color fallback feature (set_color 313554 blue) that's been
present quite a while.
The `set_color normal` text had a comment that caused
the example to wrap to the next line in an 80 column window.
Shorten the comment so the example fits on one line.
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.
Restores erroneous changes to lexicon_filter and changes to doc_src/ pages. Done by hand to ensure version history.
Fixes display of % when misinterpreted by Doxygen.
Make `fish_indent`, `fish_key_reader` and `fish` recognize and assign
the same meaning to the `-d` and `-D` flags. Also, fix some errors and
stylistic issues in the associated man pages.
Fixes#3191
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.
This change allows the user to specify the script name on the CLI in addition
to being redirected from stdin. It also adds a `-w` flag to write the modified
script to the original file.
This change does several things. First, and most important, it allows
dumping the "n" most recent stack frames on each debug() call. Second,
it demangles the C++ symbols. Third, it prepends each debug() message
with the debug level.
Unrelated to the above I've replaced all `assert(!is_forked_child());`
statements with `ASSERT_IS_NOT_FORKED_CHILD()` for consistency.
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.
Fixes#3000
The original `key_reader` program was useful but didn't do much that `xxd`
or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by
default. This change adds features that make it superior to those programs
for decoding interactive key presses and makes it a first-class citizen
like the `fish_indent` program that is always available.
Fixes#2991
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"`.
Resolves#1643
* Add missing color definitions to __fish_init_1_50_0 reset.
The values where determined by inspecting the values of:
* fish_color_end
* fish_color_user
* fish_color_host
after resetting the color theme via fish_config.
* Add documentation for fish_color_user and fish_color_host.
I noticed that Doxygen was also complaining about the "<asis>" and "<bs>"
tags. So convert those to the backslash form like we did for "<outp>" in the
previous commit.
Doxygen has been warning that `<outp>` and `</outp>` are not valid XML/HTML commands since commit cb6d5d76 on 20016-04-04. That's primarily because there is at present no way to tell Doxygen to recognize new XML/HTML tags. The actual errors look like this:
```
.../string.doxygen:187: warning: Unsupported xml/html tag </outp> found
```
I hate build errors since they a) cause needless concern, and b) make it harder to notice when I've introduced a new error. So switch from XML/C## style markup to Doxygen style markup for the "outp" annotation.
Modify `fish_indent` to emit redirections without a space before the target of
the redirection; e.g., "2>&1" rather than "2>& 1" as the former is clearer to
humans.
Fixes#2899
I didn't notice when I merged commit cb6d5d76c8
by thebespokepixel.com that it removed the explicit wrapping in the `string`
man page. That makes `man string` harder to read so reinstate the explicit
wrapping.
- Add options to the autotools build to set the path for the "vendor"
or "extra" configuration snippets, functions and completions
directories.
- Remove the vendor_completions directory from the Xcode build, as
these are relocatable and compiling the paths in does not make sense.
This allows packaging tools like Homebrew and Nix to use a common
directory outside of the main prefix for third-party completions, and
to make these available for programmatic discovery through `pkg-config`.

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 2836
The swap-selection-start-stop function goes to the other end of the highlighted text, the equivalent of `o' for vim visual mode.
Add binding to the swap-selection-start-stop function, `o' when in visual
mode.
Document swap-selection-start-stop, begin-selection, end-selection, kill-selection.
We silently upgrade existing abbreviations and change the separator when
saving.
This does not yet warn when the user is using the old syntax.
Resolves#2051
This narrows the range of Unicode codepoints fish reserves for its own
use from U+E000 thru U+F8FE (6399 codepoints) to U+F600 thru U+F73F (320
codepoints). This is still not ideal since fish shouldn't be using any
Unicode private-use codepoints but it's a step in the right direction.
This partially addresses issue #2684.
This allows "vendors" (i.e. third-party upstreams interested in
supporting fish) to add auto-loaded functions and eager-loaded
configuration "snippets", while still allowing both the user and the administrator to
fully override all of that.
This has been inspired by systemd's configuration hierarchy, and implements a similar scheme
whereby files with the same name in higher-ranking directories override files in lower-ranking ones.
Fixes#1956
Expand globs to zero arguments (nullglob) only for set, for and count.
The warning about failing globs, and setting the accompanying $status,
now happens regardless of mode, interactive or not.
It is assumed that the above commands are the common cases where
nullglob behaviour is desirable.
More importantly, doing this with `set` is a real feature enabler,
since the resulting empty array can be passed on to any command.
The previous behaviour was actually all nullglob (since commit
cab115c8b9), but this was undocumented;
the failglob warning was still printed in interactive mode,
and the documentation was bragging about failglob behaviour.
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.
This fixes all but one of the warnings documented in issue #2685. The
sole remaining warning is from the
string split '' abc
example in doc_src/string.txt. That example results in the man page
displaying
string split {} abc
I leave it to someone else to fix that problem (I'll open an issue
specifically for it since it took some effort to track down the source
of the warning).
Resolves issue #2685.
This is meant to make it clear that fish cannot control the terminal
window background color. It also augments the set_color documentation to
describe how it decides which color the terminal can display.
Resolves#2421.
Resolves#2184.
The random builtin command may or may not produce values with a truly
random distribution. So make the documentation reflect that reality. Also,
make the command consistent with similar shells (e.g., bash, zsh) which
produce a range of [0..32767].
Resolves issue #1272.
* Add a note to the `--wrap` docs saying that wrapping only works when
specifying completions for commands, not for paths.
* Add more info about how `--arguments` is handled.
* Indicate which options can be repeated in the usage lines.
* Reorder the options in usage slightly to group better.
* Reorder the option descriptions to match the order as seen in usage.
* Update some of the option descriptions.
* Fix the documentation for -C to show that it must be `-CSTRING`
instead of `-C STRING`.
* Document the behavior of `-C` with no argument.
* Tweak some of the explanatory text after the option list.
* Delete `--authoritative` and `--unauthoritative` from the
documentation entirely. Those options appear to not actually do
anything in the new parser.
The special token "normal" should not be in the basic sixteen color table
because a) it is not a color, and b) it is special cased with the result of
resetting the terminal colors (usually via a ANSI X3.64 CSI [0m sequence).
This adds support for the ANSI x3.64 "bright" colors in the basic sixteen
color palette. This is especially useful when trying to use the base colors
as a background color. The "bright" variants tend to be more useful as
background colors compared to the non-bright variants.
This also fixes a bug in so far as palette number 7 is actually grey and
not white whereas palette number 15 is white. At least on the terminal
emulators on which I've tested this change (Ubuntu xterm & uxterm, Mac
OS X Terminal & iTerm2).
Resolves issue #1464.
