* When using a UTF-8 locale, set locale to C temporarily in order to
read one byte at a time.
* Use the builtin printf in a forward-compatible way. (GNU)
* Improve the readability of the code.
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.
Fixes the invocation of a user-specified browser by the `help` command on Cygwin.
- Use `cygstart` to launch the browser with escaped quotes to avoid problems with spaces in the path to the browser, (e.g. Program Files).
- Use `cygpath` to convert the base help dir to a Windows path before constructing the fie URL to pass to the browser.
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.
