The values for notification hooks remain available as comments, but this
prevents notifications from other repositories from automatically being
linked across to the official notification channels.
The argv argument may be modified on calls to exchange within the function and should not be const qualified (it's not true from the caller's point of view).
On arm, wchar_t is unsigned, and C++11 and newer disallow implicit
narrowing conversions inside braces. Use an explicit conversion to
fix the build on GCC 6 and up, which defaults to C++11.
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.
All versions of fish prior to this change silently discarded anything written
to stderr while source a config.fish file. Apparently just to avoid having
the source command display an error if the file did not exist. This can mask
real problems. So instead this change explicitly checks whether the file is
readable and silently skips sourcing it if it isn't.
Resolves issue #2702.
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.
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.
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.
