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.
This reverts commit 7a74198aa3.
Believe it or not this commit actually increased copying. When accepting
a value you know you're going to take ownership of, just accept it by
value; then temporaries can invoke the move ctor and blah blah blah.
We really need a lightweight refcounted pass-by-value string to make this
less error prone.
Mostly related to usage _(L"foo"), keeping in mind the _
macro does a wcstring().c_str() already.
And a smattering of other trivial micro-optimizations certain
to not help tangibly.
Rather than having tokenizer_error as pointers to objects, switch it back
to just an error code value. This makes reasoning about it easier since
it's immutable values instead of mutable objects, and it avoids allocation
during startup.
Work around #4810 by retrieving localizations at runtime to avoid issues
possibly caused by inserting into the static unordered_map during static
initialization.
Closes#810.
Prior to this fix, each redirection type was a separate token_type.
Unify these under a single type TOK_REDIRECT and break the redirection
type out into a new sub-type redirection_type_t.
The previous attempt to support newlines after pipes changed the lexer to
swallow newlines after encountering a pipe. This has two problems that are
difficult to fix:
1. comments cannot be placed after the pipe
2. fish_indent won't know about the newlines, so it will erase them
Address these problems by removing the lexer behavior, and replacing it
with a new parser symbol "optional_newlines" allowing the newlines to be
reflected directly in the fish grammar.
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
This does several things. It fixes `builtin_function()` so that errors it
emits are displayed. As part of doing that I've removed the unnecessary
`out_err` parameter to make the interface like every other builtin.
This also fixes a regression introduced by #4000 which was attempting to
fix a bug introduced by #3649.
Fixes#4139
Switch from null terminated arrays to `wcstring_list_t` for lists of
special env var names. Rename `list_contains_string` to `contains` and
modify the latter interface to not rely on a `#define`.
Rename `list_contains_string()` to `contains()` and eliminate the
current variadic implementation. Update all callers of the removed
version to use the string list version.
I recently upgraded the software on my macOS server and was dismayed to
see that cppcheck reported a huge number of format string errors due to
mismatches between the format string and its arguments from calls to
`assert()`. It turns out they are due to the macOS header using `%lu`
for the line number which is obviously wrong since it is using the C
preprocessor `__LINE__` symbol which evaluates to a signed int.
I also noticed that the macOS implementation writes to stdout, rather
than stderr. It also uses `printf()` which can be a problem on some
platforms if the stream is already in wide mode which is the normal case
for fish.
So implement our own `assert()` implementation. This also eliminates
double-negative warnings that we get from some of our calls to
`assert()` on some platforms by oclint.
Also reimplement the `DIE()` macro in terms of our internal
implementation.
Rewrite `assert(0 && msg)` statements to `DIE(msg)` for clarity and to
eliminate oclint warnings about constant expressions.
Fixes#3276, albeit not in the fashion I originally envisioned.
