The relevant standards allow the mbtowc/mbrtowc functions to reject
non-ASCII characters (i.e., chars with the high bit set) when the locale
is C or POSIX. The BSD libraries (e.g., on OS X) don't do this but
the GNU libraries (e.g., on Linux) do. Like most programs we need the
C/POSIX locales to allow arbitrary bytes. So explicitly check if we're
in a single-byte locale (which would also include ISO-8859 variants)
and simply pass-thru the chars without encoding or decoding.
Fixes#2802.
I noticed while fixing issue #2702 that the fish program being tested
was sourcing config.fish files outside of the current build. This also
happens when Travis CI runs the tests but isn't an issue there because
of how Travis is configured to execute the tests.
I also noticed that running `make test` was polluting my personal fish
history; which will become a bigger problem if and when the fishd universal
var file is moved from $XDG_CONFIG_HOME to $XDG_DATA_HOME.
This change makes it possible for an individual to run the tests on
their local machine secure in the knowledge that only the config.fish and
related files from their git repository will be used and doing so won't
pollute their personal fish history.
Resolves#469
pcre2_substitute() now sets the output buffer length to PCRE2_UNSET (~0)
if the output buffer is determined to be too small. This change keeps
track of the buffer size separately where pcre2 can't touch it.
A better fix would be to let pcre2 tell fish what size buffer it needs.
This can be done with PCRE2_SUBSTITUTE_OVERFLOW_LENGTH, but this
requires pcre2 10.21 or later (released January 12), which may be too
new to introduce as a dependency at this point.
Fixes#2743
I've run this more than twenty times through Travis CI (by adding/removing
a comment line). Without this tweak the longest sequence seems to be
around six successful runs.
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.
My previous commit failed in the travis-ci environment despite passing on my
local computer. This appears to be due to expect timing out looking for the
expected input. See if increasing the expect timeout slightly fixes the
problem.
Introduce a "fish_escape_delay_ms" variable to allow the user to configure the
delay used when seeing a bare escape before assuming no other characters will
be received that might match a bound character sequence. This is primarily
useful for vi mode so that a bare escape character (i.e., keystroke) can
switch to vi "insert" to "normal" mode in a timely fashion.
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.
The fix for #2075 inadvertently started unescaping the strings emitted
from `commandline -b`. Only strings emitted with the `-o` flag are
supposed to be unescaped.
Fixes#2210.
Previously 'set -ql' would only look for variables in the
immediate local scope. This was not very useful. It's also
arguably surprising, since a 'set -l' in a function, followed
by a 'set -ql' in a child block, would fail. There was also no
way to check for a function-scoped variable, since omitting the
scope would also pull in global variables.
We could revisit this and introduce an explicit function scope.
Fixes#2502
This isn't pretty, but it fails for, as far as I can see, no _real_
reason.
It doesn't seem to be possible to trigger the failure in real usage, no
matter how fast you press the ESC key followed by something else.
So now this is known and constant travis emails don't help it in any way.
When performing wildcard expansion with a literal path segment,
instead of enumerating the files in the directory, simply apply the
path segment as if we found the directory and continue on. This
enables us to expand strings that contain unreadable directory
components (common with $HOME) and also improves performance, since
we don't waste time enumerating directories unnecessarily. Adds
a test too.
Fixes#2099
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
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.
Before running a command, we add the command to history, so
that if the command causes us to exit it's still captured in
history. But that command should not be considered part of
history when expanding the history within the command itself.
For example, `echo $history[1]` should be the previously
run command, not `echo $history[1]` itself.
Fixes#2028
GNU and BSD `mktemp` handle options differently, and it's a useful
utility for tests. As such, define a common `mktemp` function wrapper
for the test suite.
It might actually be nice to expand this for more flags and support it
globally, but that may result in confusion for any users of BSD mktemp
that expect to be running /bin/mktemp.
Update the test runners so they set up their own environment in
test_util.fish. This simplifies the Makefile and paves the way for
adding utility functions for use in the tests themselves.
