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.
Line continuations (i.e. escaped new lines) now make sense again. With
the smart pipe support (pipes continue on to next line) recently added,
this hack to have continuations ignore comments makes no sense.
This is valid code:
```fish
echo hello |
# comment here
tr -d 'l'
```
this isn't:
```fish
echo hello | \
# comment here
tr -d 'l'
```
Reverts @snnw's 318daaffb2Closes#2928. Closes#2929.
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.
Prior to this the tokenizer ran "one ahead", where tokenizer_t::next()
would in fact return the last-parsed token. Switch to parsing on demand
instead of running one ahead; this is simpler and prepares for tokenizer
changes.
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.
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes#2957
When an error occurs midway through a token, like abc(def,
make the caret point at the location of the error (i.e. the paren)
instead of at the beginning of the token.
This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes#1866
