This switches fish to a "virtual" PWD, where it no longer uses getcwd to
discover its PWD but instead synthesizes it based on normalizing cd against
the $PWD variable.
Both pwd and $PWD contain the virtual path. pwd is taught about -P to
return the physical path, and -L the logical path (which is the default).
Fixes#3350
This new function performs normalization of paths including dropping
/./ segments, and resolving /../ segments, in preparation for switching
fish to a "virtual" PWD.
Coalesces commands with leading (if even possible) and trailing
whitespace into the same item, improving the experience when iterating
over history entries.
Closes#4908.
If the replacement in `string replace` is invalid, prior to this fix we would
enter into an infinite loop trying to parse it. Instead report errors correctly.
Fixes#3381
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.
Factor the history search fields into a new class.
As a side effect, this shares the deduplication logic, so that token search
no longer returns duplicates.
Fixes#4795
separated_buffer_t encapsulates the logic around discarding (which
was previously duplicated between output_stream_t and io_buffer_t),
and will also encapsulate the logic around explicitly separated
output.
While supported by gcc and clang, \e is a gcc-specific extension and not
formally defined in the C or C++ standards.

This partially reverts 5b489ca30f, with
carets acting as redirections unless the stderr-nocaret flag is set.
This flag is off by default but may be enabled on the command line:
fish --features stderr-nocaret
This introduces a new command line option --features which can be used for
enabling or disabling features for a particular fish session.
Examples:
fish --features stderr-nocaret
fish --features 3.0,no-stderr-nocaret
fish --features all
Note that the feature set cannot be changed in an existing session.
This introduces a new type features_t that exposes feature flags. The intent
is to allow a deprecation/incremental adoption path. This is not a general
purpose configuration mechanism, but instead allows for compatibility during
the transition as features are added/removed.
Each feature has a user-presentable short name and a short description. Their
values are tracked in a struct features_t.
We start with one feature stderr_nocaret, but it's not hooked up yet.
This switches the universal variables file from a machine-specific
name to the fixed '.config/fish/fish_universal_variables'. The old file
name is migrated if necessary.
Fixes#1912
This removes the caret as a shorthand for redirecting stderr.
Note that stderr may be redirected to a file via 2>/some/path...
and may be redirected with a pipe via 2>|.
Fixes#4394
This enables some limited use of arguments for wrapping completions. The
simplest example is that complete gco -w 'git checkout' now works like
you would want: `gco <tab>` now invokes git's completions with the
`checkout` argument prepended.
Fixes#1976
Previously, in
ls ^a bcd
(with "^" as the cursor), kill-word would delete the "a" and then go
on, remove the space and the "bcd".
With this, it will only kill the "a".
Fixes#4747.
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.
Prior to this fix, if you attempt to complete from inside a quote and the
completion contained an entity that cannot be represented inside quotes
(i.e. \n \r \t \b), the result would be a broken mess of quotes. Rewrite
the implementation so that it exits the quotes, emits the correct unquoted
escape, and then re-enters the quotes.
