2023-01-26Auto merge of #106745 - m-ou-se:format-args-ast, r=oli-obkbors-1/+3
Move format_args!() into AST (and expand it during AST lowering) Implements https://github.com/rust-lang/compiler-team/issues/541 This moves FormatArgs from rustc_builtin_macros to rustc_ast_lowering. For now, the end result is the same. But this allows for future changes to do smarter things with format_args!(). It also allows Clippy to directly access the ast::FormatArgs, making things a lot easier. This change turns the format args types into lang items. The builtin macro used to refer to them by their path. After this change, the path is no longer relevant, making it easier to make changes in `core`. This updates clippy to use the new language items, but this doesn't yet make clippy use the ast::FormatArgs structure that's now available. That should be done after this is merged.

2022-12-12Auto merge of #105160 - nnethercote:rm-Lit-token_lit, r=petrochenkovbors-48/+94
Remove `token::Lit` from `ast::MetaItemLit`. Currently `ast::MetaItemLit` represents the literal kind twice. This PR removes that redundancy. Best reviewed one commit at a time. r? `@petrochenkov`
2022-12-05Remove `LitKind::synthesize_token_lit`.Nicholas Nethercote-39/+44
It has a single call site in the HIR pretty printer, where the resulting token lit is immediately converted to a string. This commit replaces `LitKind::synthesize_token_lit` with a `Display` impl for `LitKind`, which can be used by the HIR pretty printer.

Make inline const block `ExprWithBlock` Fix https://github.com/rust-lang/rust/pull/104087#issuecomment-1324190817 `@rustbot` label: +T-lang +F-inline_const
2022-12-02Remove `token::Lit` from `ast::MetaItemLit`.Nicholas Nethercote-2/+25
`token::Lit` contains a `kind` field that indicates what kind of literal it is. `ast::MetaItemLit` currently wraps a `token::Lit` but also has its own `kind` field. This means that `ast::MetaItemLit` encodes the literal kind in two different ways. This commit changes `ast::MetaItemLit` so it no longer wraps `token::Lit`. It now contains the `symbol` and `suffix` fields from `token::Lit`, but not the `kind` field, eliminating the redundancy.
2022-12-02Add `StrStyle` to `ast::LitKind::ByteStr`.Nicholas Nethercote-5/+11
This is required to distinguish between cooked and raw byte string literals in an `ast::LitKind`, without referring to an adjacent `token::Lit`. It's a prerequisite for the next commit.
2022-12-02Rename `LitKind::to_token_lit` as `LitKind::synthesize_token_lit`.Nicholas Nethercote-2/+2
This makes it clearer that it's not a lossless conversion, which I find helpful.

2022-11-29Avoid more `MetaItem`-to-`Attribute` conversions.Nicholas Nethercote-9/+0
There is code for converting `Attribute` (syntactic) to `MetaItem` (semantic). There is also code for the reverse direction. The reverse direction isn't really necessary; it's currently only used when generating attributes, e.g. in `derive` code. This commit adds some new functions for creating `Attributes`s directly, without involving `MetaItem`s: `mk_attr_word`, `mk_attr_name_value_str`, `mk_attr_nested_word`, and `ExtCtxt::attr_{word,name_value_str,nested_word}`. These new methods replace the old functions for creating `Attribute`s: `mk_attr_inner`, `mk_attr_outer`, and `ExtCtxt::attribute`. Those functions took `MetaItem`s as input, and relied on many other functions that created `MetaItems`, which are also removed: `mk_name_value_item`, `mk_list_item`, `mk_word_item`, `mk_nested_word_item`, `{MetaItem,MetaItemKind,NestedMetaItem}::token_trees`, `MetaItemKind::attr_args`, `MetaItemLit::{from_lit_kind,to_token}`, `ExtCtxt::meta_word`. Overall this cuts more than 100 lines of code and makes thing simpler.

2022-11-28Remove `Lit::from_included_bytes`.Nicholas Nethercote-8/+0
`Lit::from_included_bytes` calls `Lit::from_lit_kind`, but the two call sites only need the resulting `token::Lit`, not the full `ast::Lit`. This commit changes those call sites to use `LitKind::to_token_lit`, which means `from_included_bytes` can be removed.

patterns.
2022-11-16Use `token::Lit` in `ast::ExprKind::Lit`.Nicholas Nethercote-22/+5
Instead of `ast::Lit`. Literal lowering now happens at two different times. Expression literals are lowered when HIR is crated. Attribute literals are lowered during parsing. This commit changes the language very slightly. Some programs that used to not compile now will compile. This is because some invalid literals that are removed by `cfg` or attribute macros will no longer trigger errors.

2022-11-11Auto merge of #99918 - WaffleLapkin:fnFnfun, r=estebankbors-0/+6
Recover wrong-cased keywords that start items (_this pr was inspired by [this tweet](https://twitter.com/Azumanga/status/1552982326409367561)_) r? `@estebank` We've talked a bit about this recovery, but I just wanted to make sure that this is the right approach :) For now I've only added the case insensitive recovery to `use`s, since most other items like `impl` blocks, modules, functions can start with multiple keywords which complicates the matter.

2022-08-16Rename some things related to literals.Nicholas Nethercote-9/+9
- Rename `ast::Lit::token` as `ast::Lit::token_lit`, because its type is `token::Lit`, which is not a token. (This has been confusing me for a long time.) reasonable because we have an `ast::token::Lit` inside an `ast::Lit`. - Rename `LitKind::{from,to}_lit_token` as `LitKind::{from,to}_token_lit`, to match the above change and `token::Lit`.
