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
After 'x' is used to delete a character at the end of a line the cursor
should be repositioned at the last character, i.e. repeatedly pressing
'x' in normal mode should delete the entire string.
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.
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.
There isn't a good reason to disallow an explicitly empty completion
description. Since I'm touching the code also modify the argument
parsing the match the style of most of the builtins.
Fixes#3557.
There was a discussion recently on Gitter about `set_color reset`. The
result was @floam creating commit bd03c3fbc to change it to `set_color
normal` in share/functions/vared.fish. This does the same for
tests/test_util.fish.
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
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 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.
Another dev noticed that tests/printf.in was failing because they didn't have
the fr_FR.UTF-8 locale installed. Make that test more resilient by trying
other locales and if no suitable locale is found skipping the test.
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
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 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.
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.
Attempting to execute something like `exec "$test"` results in a fish internal
token (a Unicode private use char) being printed in the resulting error
message. That's obviously not desirable as well as confusing.
Fixes#3187
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
The tests/*.status files aren't useful so eliminate them. Just verify whether
a given test module exited with a success status. There isn't any point in
having a "status" file that indicates the test module should exit with a
success (zero) status.
Closes#3208Closes#3209
I did some research and experiments. For good or bad the `bind` command
requires the use of wide char codepoints (e.g., \u1234) for non-ASCII
chars. So don't force the use of the POSIX locale, but do provide it as
an option for people who want to see the individual bytes rather than a
decoded wide char.
Simplify the format of the information displayed for each character. There
really isn't much point in providing decimal, octal, and hexadecimal. Just
print hex and symbolic representations.
Add an example `bind` command that a user can copy/paste.
Closes#3183
Another developer noticed that redirecting stdin of `fish_key_reader`
results in weird behavior. Which is not at all surprising. So add checks
to ensure stdin and stdout are attached to a tty.
Add some rudimentary unit tests for this program.
For example, an argument 12345^ is a real argument, not a redirection
There's no reason to use ^ here instead of >, and it's annoying to git
users.
Fixes#1873
Fix test setup bogosities. Specifically, they weren't hermetic with respect to
locale env vars.
Rewrite the handling of locale vars to simplify the code and make it more like
the pattern most programs employ.
Fixes#3110
Configure the tty driver to ignore the lnext (\cV) and werase (\cW) characters
so they can be bound to fish functions.
Correct the `fish_key_bindings` program to initialize the tty in the same
manner as the `fish` program.
Fixes#3064
Previously, `--erase` would not accept any options and wouldn't read
"--" as option-separator. Now it does like every other "command", and it
could conceivably gain e.g. a "--prefix" option.
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
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
