Add parser improvements (#2679)
* Add parser improvements

Previously everything starting with "$" was parsed as a column path.
With this commit applied, the lite_arg starting with $ is parsed as
the most appropriate thing
- $true/$false ==> Expression::Boolean
- $(...) ==> Invocation
- $it ==> ColumnPath
- Anything with at least one '.' ==> ColumnPath
- Anything else ==> Variable

* Ignore failing tests

Implement exclusive and inclusive ranges with ..< and .. (#2541)
* Implement exclusive and inclusive ranges with .. and ..=

This commit adds right-exclusive ranges.

The original a..b inclusive syntax was changed to reflect the Rust notation.
New a..=b syntax was introduced to have the old behavior.

Currently, both a.. and b..= is valid, and it is unclear whether it's valid
to impose restrictions.

The original issue suggests .. for inclusive and ..< for exclusive ranges,
this can be implemented by making simple changes to this commit.

* Fix collect tests by changing ranges to ..=

* Fix clippy lints in exclusive range matching

* Implement exclusive ranges using `..<`

Have lite-parse complete return a complete bare form. (#2389)
Previously, lite parse would stack up opening delimiters in vec, and if we
didn't close everything off, it would simply return an error with a partial form
that didn't include the missing closing delimiters. This commits adds those
delimiters so that `classify_block` can parse correctly.

Add method to convert ClassifiedBlock into completion locations. (#2316)
The completion engine maps completion locations to spans on a line, which
indicate whther to complete a command name, flag name, argument, and so on.

Initial implementation is simplistic, with some rough edges, since it relies
heavily on the parser's interpretation. For example

    du -

if asking for completions, `-` is considered a positional argument by the
parser, but the user is likely looking for a flag. These scenarios will be
addressed in a series of progressive enhancements to the engine.

Return incomplete parse from lite_parse (#2284)
* Move lite_parse tests into a submodule

* Have lite_parse return partial parses when error encountered.

Although a parse fails, we can generally still return what was successfully
parsed. This is useful, for example, when figuring out completions at some
cursor position, because we can map the cursor to something more structured
(e.g., cursor is at a flag name).

Remove custom escaping for external args. (#2095)
Our own custom escaping unfortunately is far too simple to cover all cases.
Instead, the parser will now do no transforms on the args passed to an external
command, letting the process spawning library deal with doing the appropriate
escaping.

Move external closer to internal (#1611)
* Refactor InputStream and affected commands.

First, making `values` private and leaning on the `Stream` implementation makes
consumes of `InputStream` less likely to have to change in the future, if we
change what an `InputStream` is internally.

Second, we're dropping `Option<InputStream>` as the input to pipelines,
internals, and externals. Instead, `InputStream.is_empty` can be used to check
for "emptiness". Empty streams are typically only ever used as the first input
to a pipeline.

* Add run_external internal command.

We want to push external commands closer to internal commands, eventually
eliminating the concept of "external" completely. This means we can consolidate
a couple of things:

- Variable evaluation (for example, `$it`, `$nu`, alias vars)
- Behaviour of whole stream vs per-item external execution

It should also make it easier for us to start introducing argument signatures
for external commands,

* Update run_external.rs

* Update run_external.rs

* Update run_external.rs

* Update run_external.rs

7efb31a4e4 Restructure and streamline token expansion (#1123)
Restructure and streamline token expansion

The purpose of this commit is to streamline the token expansion code, by
removing aspects of the code that are no longer relevant, removing
pointless duplication, and eliminating the need to pass the same
arguments to `expand_syntax`.

The first big-picture change in this commit is that instead of a handful
of `expand_` functions, which take a TokensIterator and ExpandContext, a
smaller number of methods on the `TokensIterator` do the same job.

The second big-picture change in this commit is fully eliminating the
coloring traits, making coloring a responsibility of the base expansion
implementations. This also means that the coloring tracer is merged into
the expansion tracer, so you can follow a single expansion and see how
the expansion process produced colored tokens.

One side effect of this change is that the expander itself is marginally
more error-correcting. The error correction works by switching from
structured expansion to `BackoffColoringMode` when an unexpected token
is found, which guarantees that all spans of the source are colored, but
may not be the most optimal error recovery strategy.

That said, because `BackoffColoringMode` only extends as far as a
closing delimiter (`)`, `]`, `}`) or pipe (`|`), it does result in
fairly granular correction strategy.

The current code still produces an `Err` (plus a complete list of
colored shapes) from the parsing process if any errors are encountered,
but this could easily be addressed now that the underlying expansion is
error-correcting.

This commit also colors any spans that are syntax errors in red, and
causes the parser to include some additional information about what
tokens were expected at any given point where an error was encountered,
so that completions and hinting could be more robust in the future.

Further separation of logic (preparing the external's command arguments, getting the data for piping, emitting values, spawning processes) will give us a better idea for lower level details regarding external commands until we can find the right abstractions for making them more generic and unify within the pipeline calling logic of Nu internal's and external's.

Inc refactoring, Value helper test method extractions, and more integration helpers. (#1135)
* Manifests check. Ignore doctests for now.

* We continue with refactorings towards the separation of concerns between
crates. `nu_plugin_inc` and `nu_plugin_str` common test helpers usage
has been refactored into `nu-plugin` value test helpers.

Inc also uses the new API for integration tests.

57af9b5040 Add Range and start Signature support
This commit contains two improvements:

- Support for a Range syntax (and a corresponding Range value)
- Work towards a signature syntax

Implementing the Range syntax resulted in cleaning up how operators in
the core syntax works. There are now two kinds of infix operators

- tight operators (`.` and `..`)
- loose operators

Tight operators may not be interspersed (`$it.left..$it.right` is a
syntax error). Loose operators require whitespace on both sides of the
operator, and can be arbitrarily interspersed. Precedence is left to
right in the core syntax.

Note that delimited syntax (like `( ... )` or `[ ... ]`) is a single
token node in the core syntax. A single token node can be parsed from
beginning to end in a context-free manner.

The rule for `.` is `<token node>.<member>`. The rule for `..` is
`<token node>..<token node>`.

Loose operators all have the same syntactic rule: `<token
node><space><loose op><space><token node>`.

The second aspect of this pull request is the beginning of support for a
signature syntax. Before implementing signatures, a necessary
prerequisite is for the core syntax to support multi-line programs.

That work establishes a few things:

- `;` and newlines are handled in the core grammar, and both count as
  "separators"
- line comments begin with `#` and continue until the end of the line

In this commit, multi-token productions in the core grammar can use
separators interchangably with spaces. However, I think we will
ultimately want a different rule preventing separators from occurring
before an infix operator, so that the end of a line is always
unambiguous. This would avoid gratuitous differences between modules and
repl usage.

We already effectively have this rule, because otherwise `x<newline> |
y` would be a single pipeline, but of course that wouldn't work.

24bad78607 Clean up expansion of external words
Previously, external words accidentally used
ExpansionRule::new().allow_external_command(), when it should have been
ExpansionRule::new().allow_external_word().

External words are the broadest category in the parser, and are the
appropriate category for external arguments. This was just a mistake.

8f9dd6516e Add =~ and !~ operators on strings
`left =~ right` return true if left contains right, using Rust's
`String::contains`. `!~` is the negated version.

A new `apply_operator` function is added which decouples evaluation from
`Value::compare`. This returns a `Value` and opens the door to
implementing `+` for example, though it wouldn't be useful immediately.

The `operator!` macro had to be changed slightly as it would choke on
`~` in arguments.

e4226def16 Extract core stuff into own crates
This commit extracts five new crates:

- nu-source, which contains the core source-code handling logic in Nu,
  including Text, Span, and also the pretty.rs-based debug logic
- nu-parser, which is the parser and expander logic
- nu-protocol, which is the bulk of the types and basic conveniences
  used by plugins
- nu-errors, which contains ShellError, ParseError and error handling
  conveniences
- nu-textview, which is the textview plugin extracted into a crate

One of the major consequences of this refactor is that it's no longer
possible to `impl X for Spanned<Y>` outside of the `nu-source` crate, so
a lot of types became more concrete (Value became a concrete type
instead of Spanned<Value>, for example).

This also turned a number of inherent methods in the main nu crate into
plain functions (impl Value {} became a bunch of functions in the
`value` namespace in `crate::data::value`).
