This adds support for `fish_trace`, a new variable intended to serve the
same purpose as `set -x` as in bash. Setting this variable to anything
non-empty causes execution to be traced. In the future we may give more
specific meaning to the value of the variable.
The user's prompt is not traced unless you run it explicitly. Events are
also not traced because it is noisy; however autoloading is.
Fixes#3427
When considering an autosuggestion from history, we attempt to validate the
command to ensure that we don't suggest invalid (e.g. path-dependent)
commands. Prior to this fix, we would validate the last command in the
command line (e.g. in `cd /bin && ./stuff` we would validate "./stuff".
This doesn't really make sense; we should be validating the first command
because it has the potential to change the PWD. Switch to validating the
first command.
Also remove some helper functions that became dead through this change.
This just makes more sense, as people don't want to enter exact
matches if they delete interactively.
It also brings it in line with "search".
Fixes#6142
Rejects #6070
Until now, something like
`math '7 = 2'`
would complain about a "missing" operator.
Now we print an error about logical operators not being supported and
point the user towards `test`.
Fixes#6096
They were just wrappers around `cmake` and caused cmake with the Makefile generator
to mark in-tree builds as dirty, since it would overwrite them with its own.
Fixes#6264
MacOS Catalina apparently ships a stripped down svn that doesn't have
`svnversion`, which we use to print the revision.
For now skip the entire step to remove error spam.
Fixes#6267.
[ci skip]
Every builtin or function shipped with fish supports flag -h or --help to
print a slightly condensed version of its manpage.
Some of those help messages are longer than a typical screen;
this commit pipes the help to a pager to make it easier to read.
As in other places in fish we assume that either $PAGER or "less" is a
valid pager and use that.
In three places (error messages for bg, break and continue) the help is
printed to stderr instead of stdout. To make sure the error message is
visible in the pager, we pass it to builtin_print_help, every call of which
needs to be updated.
Fixes#6227
Some distros (Arch) use python command for Python 3, so we need to update the scripts to work with it. We cannot just switch to python3 command because MacOS does not ship it.
* functions/__fish_print_hostnames: Fix ssh_configs no values return
`string replace` not working with mutlilines variable.
So split per line first.
* functions/__fish_print_hostnames: remove quotes at `split '\n'`
"\n with quotes" will cause `string split` weird issues.
* functions/__fish_print_hostnames: using `read -alz -d \n`
Fix `$contents` issues together
