Doing `set -U var` when a global named `var` exists can result in
confusing behavior. Try to limit the confusion by improving the warning
we write. Also, only write the warning if interactive.
Fixes#4267
I decided this was just too useful not to include in our final fish 2.x
release. And since it does not modify any existing behavior it is safe
to include at this late date in the process of creating 2.7.
This silences warnings from the compiler about ignoring return value of
‘ssize_t write(int, const void*, size_t)’, declared with attribute
warn_unused_result [-Wunused-result].
The class `completer_t` declares `complete_special_cd`, an unused method. I searched the entire source tree and this declaration seems to be the only instance of `complete_special_cd`. There is no definition or uses which likely means this is dead code.
* Make npm run-script completion faster with `jq`
When jq is available, it's actually faster to invoke jq and parse the `package.json`
invoking the `npm` command.
Also, prior to this commit, both `__fish_complete_npm` and `__fish_npm_run` were being run
whenever completions for `npm run` subcommand was being used, which was actually making
repetitive work (invoking npm command twice). This pull request is supposed to make completion
without `jq` faster as well
* Refactor npm.fish for code reutilization
Created function to handle both cases of npm run completion parse, with or without `jq` completion.
* Remove unecessary blank line
When reporting whether a boolean flag was seen report the actual flags
rather than a summary count. For example, if you have option spec `h/help`
and we parse `-h --help -h` don't do the equivalent of `set _flag_h 3`
do `set _flag_h -h --help -h`.
Partial fix for #4226
In the rare case that we don't inherit $HOME _and_ can't read it from
/etc/passwd, this makes it so instead of triggering an assert() $HOME
is set to the empty list.
Tilde-expansion expands to nothing in such a case (and a string-empty
$HOME), `cd` errors out.
Fixes#4229.
Fish 2.6.0 introduced a regression that keeps setting
`fish_escape_delay_ms` as a uvar from working. This also fixes a related
problem: callbacks generated from the initial loading of universal vars
were not being acted on.
Fixes#4196
Also stop special-casing `printf` as if it were a syntactical keyword
with respect to handling `printf --help`. It should use the same pattern
as every other builtin command.
The code for reporting parser errors needs a major overhaul. But rather
than do that I'm going to add another hack in the hope that this doesn't
introduce yet another problem.
Fixes#4221
The recent change to switch `psub` to use `argparse` caused it to use
a fifo by default because it inadvertently fixed a long standing bug in
the fish script. This changes the behavior back to `psub --file` being
the default behavior and introduces a `--fifo` flag. It also updates the
documentation to make it clearer when and why `--fifo` mode should not
be used.
Fixes#4222
While updating the `history` function to use `argparse` I realized it is
useful to define an option that can be used in three ways. First by
using the short flag; e.g., `-n NNN`. Second by using the long flag;
e.g., `--max NNN`. Third, as an implicit int flag; e.g., `-NNN`. This
use case is now supported by a spec of the form `n#max`.
