Add support for real comparison operators #7

sophiajt · 2019-05-18T01:28:36Z

Adds support for ==, !=, <, >, <=, and >=.

* Implement initial unicode movement and repaint * Finish updating unicode navigation

Tests for lex and lite parser

# Description follow up to #8529 cleaned up version of #8892 - the original syntax is okay ```nu def okay [rec: record] {} ``` - you can now add type annotations for fields if you know them before hand ```nu def okay [rec: record<name: string>] {} ``` - you can specify multiple fields ```nu def okay [person: record<name: string age: int>] {} # an optional comma is allowed def okay [person: record<name: string, age: int>] {} ``` - if annotations are specified, any use of the command will be type checked against the specified type ```nu def unwrap [result: record<ok: bool, value: any>] {} unwrap {ok: 2, value: "value"} # errors with Error: nu::parser::type_mismatch × Type mismatch. ╭─[entry #4:1:1] 1 │ unwrap {ok: 2, value: "value"} · ───────┬───── · ╰── expected record<ok: bool, value: any>, found record<ok: int, value: string> ╰──── ``` > here the error is in the `ok` field, since `any` is coerced into any type > as a result `unwrap {ok: true, value: "value"}` is okay - the key must be a string, either quoted or unquoted ```nu def err [rec: record<{}: list>] {} # errors with Error: × `record` type annotations key not string ╭─[entry #7:1:1] 1 │ def unwrap [result: record<{}: bool, value: any>] {} · ─┬ · ╰── must be a string ╰──── ``` - a key doesn't have to have a type in which case it is assumed to be `any` ```nu def okay [person: record<name age>] {} def okay [person: record<name: string age>] {} ``` - however, if you put a colon, you have to specify a type ```nu def err [person: record<name: >] {} # errors with Error: nu::parser::parse_mismatch × Parse mismatch during operation. ╭─[entry #12:1:1] 1 │ def unwrap [res: record<name: >] { $res } · ┬ · ╰── expected type after colon ╰──── ``` # User-Facing Changes **[BREAKING CHANGES]** - this change adds a field to `SyntaxShape::Record` so any plugins that used it will have to update and include the field. though if you are unsure of the type the record expects, `SyntaxShape::Record(vec![])` will suffice

# Description While #11057 is merged, it's hard to tell the difference between `--flag: bool` and `--flag`, and it makes user hard to read custom commands' signature, and hard to use them correctly. After discussion, I think we can deprecate `--flag: bool` usage, and encourage using `--flag` instead. # User-Facing Changes The following code will raise warning message, but don't stop from running. ```nushell ❯ def florb [--dry-run: bool, --another-flag] { "aaa" }; florb Error: × Deprecated: --flag: bool ╭─[entry #7:1:1] 1 │ def florb [--dry-run: bool, --another-flag] { "aaa" }; florb · ──┬─ · ╰── `--flag: bool` is deprecated.
