This adds a new mechanism for logging, intended to replace debug().
The entry points are FLOG and FLOGF. FLOG can be used to log a sequence of
arguments, FLOGF is for printf-style formatted strings.
Each call to FLOG and FLOGF requires a category. If logging for a category
is not enabled, there is no effect (and arguments are not evaluated).
Categories may be enabled on the command line via the -d option.
This way we use our core file completion code, which is much more
flexible than we can easily achieve directly in script (which would
require e.g. an `expand` builtin, and case-insensitive globs).
Fixes#5896.
Now that our interactive signal handlers are a strict superset of
non-interactive ones, there is no reason to "reset" signals or take action
when becoming non-interactive. Clean up how signal handlers get installed.
The signal handlers for interactive and non-interactive SIGINT were distinct
and talked to the reader. This wasn't really justified and will complicate
having multiple threads. Unify these into a single signal handler.
is_interactive_read is a suspicious flag which prevents a call to
parser_t::skip_all_blocks from a ^C signal handler. However we end
up skipping the blocks later when we exit the read loop.
This flag seems unnecessary. Bravely remove it.
When setting a variable without a specified scope, we should give priority
to an existing local or global above an existing universal variable with
the same name.
In 16fd780484 there was a regression that
made universal variables have priority.
Fixes#5883
This displays a colored prompt, which we emulate by adding explicit
roles that are translated to css classes.
For other things, like "eror" this might not be enough because those
often need the rest of the line to still be styled, and I've not found
a way to add some explicit styling to a code block.
See #5696.

Otherwise we'd undo the history search when you press e.g. execute,
which means you'd execute the search term.
Only `cancel` should walk it back, like it previously did hardcoded to
escape.
Fixes#5891.
These were inadvertently disabled by a bug which was introduced in
cd7e8f4103 . Fix the bug so the tests run
again.
They don't all pass yet; they regressed during the period they were
disabled.
This mainly is conceptually a bit simpler. The comment about making it
cheaper is entirely misplaced since this is quite far away from being
important.
Even expanding 1000 abbrs, it doesn't show up in the profile.
