Make pretty-expanded-hygiene a `ui` test `normalize-stdout-test` removes the need for Make, and it can be updated with `--bless` this way 2019-07-15 21:26:45 +00:00			`// check-pass`

rustc: implement a pretty mode to print ident/name's ctxt & gensyms. `--pretty expanded,hygiene` is helpful with debugging macro issues, since two identifiers/names can be textually the same, but different internally (resulting in weird "undefined variable" errors). 2014-08-11 12:01:37 +00:00			`// minimal junk`

Improve `print_tts` by changing `tokenstream::Spacing`. `tokenstream::Spacing` appears on all `TokenTree::Token` instances, both punct and non-punct. Its current usage: - `Joint` means "can join with the next token and that token is a punct". - `Alone` means "cannot join with the next token or can join with the next token but that token is not a punct". The fact that `Alone` is used for two different cases is awkward. This commit augments `tokenstream::Spacing` with a new variant `JointHidden`, resulting in: - `Joint` means "can join with the next token and that token is a punct". - `JointHidden` means "can join with the next token and that token is a not a punct". - `Alone` means "cannot join with the next token". This drastically improves the output of `print_tts`. For example, this: ``` stringify!(let a: Vec<u32> = vec![];) ``` currently produces this string: ``` let a : Vec < u32 > = vec! [] ; ``` With this PR, it now produces this string: ``` let a: Vec<u32> = vec![] ; ``` (The space after the `]` is because `TokenTree::Delimited` currently doesn't have spacing information. The subsequent commit fixes this.) The new `print_tts` doesn't replicate original code perfectly. E.g. multiple space characters will be condensed into a single space character. But it's much improved. `print_tts` still produces the old, uglier output for code produced by proc macros. Because we have to translate the generated code from `proc_macro::Spacing` to the more expressive `token::Spacing`, which results in too much `proc_macro::Along` usage and no `proc_macro::JointHidden` usage. So `space_between` still exists and is used by `print_tts` in conjunction with the `Spacing` field. This change will also help with the removal of `Token::Interpolated`. Currently interpolated tokens are pretty-printed nicely via AST pretty printing. `Token::Interpolated` removal will mean they get printed with `print_tts`. Without this change, that would result in much uglier output for code produced by decl macro expansions. With this change, AST pretty printing and `print_tts` produce similar results. The commit also tweaks the comments on `proc_macro::Spacing`. In particular, it refers to "compound tokens" rather than "multi-char operators" because lifetimes aren't operators. 2023-08-08 01:43:44 +00:00			`macro_rules! foo /* 0#0 */ { ($x: ident) => { y + $x } }`

Add and use more static symbols. Note that the output of `unpretty-debug.stdout` has changed. In that test the hash values are normalized from a symbol numbers to small numbers like "0#0" and "0#1". The increase in the number of static symbols must have caused the original numbers to contain more digits, resulting in different pretty-printing prior to normalization. 2020-07-08 01:04:10 +00:00			`fn bar /* 0#0 */() {`
