This reads any additional positional arguments given to `fish -c` into
$argv.
We don't handle the first argument specially (as `$0`) as that's confusing and
doesn't seem very useful.
Fixes#2314.
Found with gcc's -Wmissing-declarations which gives warnings like
../src/tinyexpr.cpp:61:5: warning: no previous declaration for ‘int get_arity(int)’ [-Wmissing-declarations]
61 | int get_arity(const int type) {
The same warnings show up for builtin functions like builtin_bg because they
currently don't include their own headers. I left that.
Also reformat the touched files.
Prior to this fix, the `exit` command would set a global variable in the
reader, which parse_execution would check. However in concurrent mode you
may have multiple scripts being sourced at once, and 'exit' should only
apply to the current script.
Switch to using a variable in the parser's libdata instead.
This pulls in widechar_width.h from commit d4e75d5bb1930291223d1.
This is a "rebuild with latest data" before we attempt a risky bugfix.
The idea here is that bisecting can separate whether any regression is
due to using the latest Unicode data, or the bug fix.
This is a set of miscellaneous cleanup for profiling.
An errant newline has been removed from 'if' statement output, which got
introduced with the new ast.
Switch from storing unique_ptr to a deque, which allocates less.
Collapse "parse" and "exec" times into just a single value "duration". The
"parse" time no longer makes sense, as we now parse ahead of time.
When fish exits, it tries to restore the foreground process group.
However this may actually steal control of the fg process group
from another process. Fix this by clearing the SIGTTOU handler so
that tcsetpgrp() will fail.
Credit to @mqudsi for awesome debugging.
Fixes#7060
It looks like the last status already contains the signal that cancelled
execution.
Also make `fish -c something` always return the last exit status of
"something", instead of hardcoded 127 if exited or signalled.
Fixes#6444
parser_t::eval indicates whether there was a parse error. It can be
easily confused with the status of the execution. Use a real type to
make it more clear.
This makes the following changes:
1. Events in background threads are executed in those threads, instead of
being silently dropped
2. Blocked events are now per-parser instead of global
3. Events are posted in builtin_set instead of within the environment stack
The last one means that we no longer support event handlers for implicit
sets like (example) argv. Instead only the `set` builtin (and also `cd`)
post variable-change events.
Events from universal variable changes are still not fully rationalized.
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 just sets some special characters that we use in the reader, so
it only needs to be done before the reader is set up.
Which, as it stands, is in env_init().
This runs build_tools/style.fish, which runs clang-format on C++, fish_indent on fish and (new) black on python.
If anything is wrong with the formatting, we should fix the tools, but automated formatting is worth it.
