This makes the output a little easier on the eyes.
Tests appear to not need any changes to pass. I always forget whether or not
littlecheck cares about whitespace.
Two different bugs completely broke `trap -p`. First bug broke filtering of
functions with trap handlers (`functions -na` prints functions separated by a
comma, not a new line). Second bug broke showing of function definitions for
traps because a refactor renamed only some call sites but references to `$i`
renamed.
These issues were introduced in a6820cbe and appear to have been caught just in
time: no released version is affected (changes made post-3.5.1).
The Dockerfiles had bitrotted some.
Get them passing again, add libpcre2-dev where we can so we aren't
hitting more servers than necessary, and reformat the bionic files so
they can share more of the same image.
- Clean up the wording a little.
- Highlight the limitations of the "debugger" more clearly and don't mislead
people into thinking it's possible to really interactively set/remove
breakpoints except in select circumstances.
Sidenote: I can't believe we're using a markup language that doesn't support
nested inline markup. What a crying shame, rST!
It's a variable that holds all potential directories. The old name
makes it confusing to look at some of its usage sites and figure out
what is actually going on because they make no sense if $dir is only one
entry.
Don't just save known color values but any values that could have been loaded
from a .theme file.
Also, refactor the theme variable name whitelist/filter in a shared "global"
variable so we never forget to update it at any of the individual use sites.
The documentation states that running `fish_config theme save` after
`fish_config theme choose [theme_name]` will result in "saving" the
currently chosen theme, but this does not match the actual behavior of
`fish_config theme save` which expects a trailing argument specifying
the name of the theme to select/persist.
Given that the documented way has been included in a release and that it
makes more sense than calling `fish_config theme save xxx` when you are
*loading from* xxx and not *saving to* xxx, this patch revises
`fish_config.fish` to support the documented behavior.
When `fish_config theme save xxx` is used, xxx is loaded w/ its specified colors
saved to the according variables in the universal scope. But if `fish_config
theme save` is used without a theme's name specified, then the currently
specified (known) fish color variables are persisted from whatever scope they're
currently in (usually in the global scope from previewing a theme) to universal
variables of the same name.
This does *not* catch color variables unknown to fish! If a theme and a
prompt agree on some variable to hold some color but it's not a color variable
known to fish, it won't be persisted!
Closes#9088.
This makes these tools usable in a pipe.
You can run
```fish
some-long-command | fish_clipboard_copy
```
to copy some command's output to your clipboard, and
```fish
fish_clipboard_paste | some-other-command
```
To feed your clipboard to some command.
When there are multiple screens worth of output and `history` is writing to the
pager, pressing Ctrl-C at the end of a screen doesn't exit the pager (`q` is
needed for that) but previously caused fish to emit an error ("write:
Interrupted system call) until we starting silently handling SIGINT in
`fd_output_stream_t::append()`.
This patch makes `history` detect when the `append()` call returns with an error
and causes it to end early rather than repeatedly trying (and failing) to write
to the output stream.
If EINTR caused by SIGINT is encountered while writing to the
`fd_output_stream_t` output fd, mark the output stream as errored and return
false to the caller but do not visibly complain.
Addressing the outstanding TODO notwithstanding, this is needed to avoid
littering the tty with spurious errors when the user hits Ctrl-C to abort a
long-running builtin's output (w/ the primary example being `history`).
The previous check was including these as relative includes, meaning the actual
system header files weren't actually being explicitly included and the check
could spuriously fail.
CMAKE_EXTRA_INCLUDE_FILES doesn't seem to have a way to specify that the
includes should be treated as system/global includes and CHECK_TYPE_SIZE() isn't
documented as being affected by any other variables that do, so switch to
another method altogether.
This requires that `struct winsize` have a member `ws_row`, but as best as I can
tell that is always the case.
Closes#9279.
