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.
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.
A discussion on Gitter proposed allowing the user to signal their desire to
exit fish_key_reader by pressing \cC or \cD twice in a row. This implements
that.
I also decided to refactor how signals are handled. Most notably receiving a
signal will no longer print a diagnostic message unless you've enabled
debugging with `-d2` (or higher level).
Improves experience during upgrades, accidentally running
an old fish with a new environment. No errors just from
printing a prompt. Fixes#3057.
Print helpful notice also when launching mismatched fish.
Autoloadable string.fish -- only create function if not builtin.
In addition to fixing the setting of the locale to C/POSIX this also
corrects several problems introduced by the commits made in the past
couple of days. As a consequence of dealing with all of this I decided
to refactor the code to simplify one of the overly long functions I
introduced in my previous change.
Fixes#3168
There is no conceivable way in which timef()'s invocation of gettimeofday()
can fail where it makes sense to continue running. Yes, one such,
legitimate, failure mode is a 32-bit kernel and the date is greater than
2038-01-19 03:14:07. If you're running a fish binary on such a system
it's time to upgrade. Otherwise, either the hardware or OS is broken.
Fixes#3167.
* Correct notice about ^C
* Move time deltas to end of the line away from the important info on
left.
* Use timef() instead of gettimteofday() ourselves
* Show time in ms (is this even useful in any unit? Maybe testing escape
delays...)
* Make init more similar to other apps.

We need to actually export the curses/terminfo env vars in order for
`setupterm()` to be able to use them. While fixing this I reworked the
fallback logic implemented by @zanchey in response to issue #1060 in
order to simplify the logic and clarify the error messages.
This does not allow someone to change the curses/terminfo env vars after
the first prompt is displayed (you can but it won't affect the current
fish process). It only makes it possible to set `TERM`, `TERMINFO`, and
`TERMINFO_DIRS` in *config.fish* or similar config file and have them be
honored by fish.
