Fixes some regressions from 35ca42413 ("Simplify some parse_util functions").
The tmux tests are not beautiful but I find them easy to write.
Probably a pexpect test would also be enough here?
The names in the implementation differed from those in the header, but
the header names were definitely better (because they correlated across
function calls).
For some reason I've seen one version of firefox use this over the one
we set in pydoctheme.css. Since we set it there in both light and dark
mode, this one should not be used.
This doesn't work.
The real thing that tells if something is read-only is
electric_var_t::readonly().
This wasn't used, and we provide no way to make a variable read-only,
which makes this an unnecessary footgun.
for PWD in foo; true; end
prints:
>..src/parse_execution.cpp:461: end_execution_reason_t parse_execution_context_t::run_for_statement(const ast::for_header_t&, const ast::job_list_t&): Assertion `retval == ENV_OK' failed.
because this used the wrong way to see if something is read-only.
env_var_t::read_only() is basically broken.
It doesn't work for $PWD, as best as I can tell no variable is
read-only except for a hardcoded list of some of the electric ones.
So we should probably remove the entire read_only and
setting_read_only mechanism.
This allows us to test that `test` takes numbers with decimal point even in comma-using locales,
to stop those pesky americans from breaking everything again.
(and yes, we use french to keep myself honest)
This breaks in comma-using locales (like my own de_DE.UTF-8), because
it still uses the locale-dependent strtod, which will then refuse to
read
1234.567
Using strtod_l (not in POSIX, I think?) might help, but might also be
a lot slower. Let's revert this for now and figure out if that is
workable.
This reverts commit fba86fb821.
fish_wcstod had a "fast path" which looked for all digits, otherwise
falling back to wcstod_l. However we now pass the C locale to wcstod_l,
so it is safe to extend the fast path to all ASCII characters.
In practice math parsing would pass strings here like "123 + 456" and
the space and + were knocking us off the fast path. benchmarks/math.fish
goes from 2.3 to 1.4 seconds with this change.
is_block is a field which supports 'status is-block', and also controls
whether notifications get posted. However there is no reason to store
this as a distinct field since it is trivially computed from the block
list. Stop storing it. No functional changes in this commit.
Through a mechanism I don't entirely understand, $PWD is sometimes
writable (so that `cd` can change it) and sometimes not.
In this case we ended up with it writable, which is wrong.
See #8179.
This didn't do all the syntax checks, so something like
fish -c 'echo foo; and $status'
complained of a missing command `0` (i.e. $status), and
fish -c 'echo foo | exec grep'
hit an assert!
So we do what read_ni does, parse each command into an ast, run
parse_util_detect_errors on it if it worked and then eval the ast.
It is possible to do this neater by modifying parser::eval, but I
can't find where.
This is slightly unclean. Even tho it would otherwise be syntactically
valid, using $status as a command is very very very likely to be an
error, like
if not $status
We have reports of this surprisingly regularly, including #2773.
Because $status can only ever be a value from 0 to 255, it is also
very unlikely to be an actual command, and that command is very
unlikely to do what you want.
So we simply point the user towards the "conditions" help section,
that should explain things.
This means, if we repaint with a shorter prompt, we won't overwrite the longer parts.
This reintroduces #8002, but that's a much rarer usecase - having a prompt that fills the entire screen,
in certain terminals.
This reverts commit d3ceba107e.
Fixes#8163.
This is opt-in through a new feature flag "ampersand-nobg-in-token".
When this flag and "qmark-noglob" are enabled, this command no longer
needs quoting:
curl https://example.com/thing?foo=bar&duran=duran
Compared to the previous approach e1570a4 ("Let '&' only separate as
the first char of a word"), this has some advantages:
1. "&&" and "&>" are no longer affected. They are still special, even
if used between tokens without spaces, like "echo bar&>foo".
Maybe this is not really *better*, but it avoids risking to annoy
users by breaking the old variant.
2. "&" is still special if at the end of a token, like in "sleep 1&".
Word movement is not affected by the semantics change, so Alt-F and
friends still stop at every "&".
Ubuntu's fish package on WSL 1 has xsel as recommended dependency,
even though there is no X server available. This change makes us
use Windows' native clipboard even when xsel is installed.
