proc-macro-utils

chore: Release proc-macro-utils version 0.10.0

Changed

• next_expression() stops at => as well, matching macro_rule's expr

chore: Release proc-macro-utils version 0.9.1

Added

• span() to TokenParser.

chore: Release proc-macro-utils version 0.9.0

Added

• *_tt functions to TokenParser.
• next_macro_rules_tt() to TokenParser.
• TokenTreeLiteral with is_string() and string().

Changed

• Breaking Change Sealed extension traits.

Fixed

• assert_expansion! was failing on nightly.

chore: Release proc-macro-utils version 0.8.0

Fixed

• bumped smallvec version to 1.5 to avoid nightly feature compilation issues.

chore: Release proc-macro-utils version 0.7.0

• Increased documentation and test coverage.

Added

• quote::ToTokens implementation for TokenParser (quote is a new default feature).
• peek_{token} and peek_n_{token} to TokenParser.
• alone to TokenTreePunct ensuring if a token is Punct its spacing is Alone
• *_alone functions to TokenParser setting the last token to Alone if it is a punctuation.
• next_n to TokenParser returning the next n tokens.
• peek_range to TokenParser returning a range of tokens.
• FromStr implementation for TokenParser based on TokenStream's.
• assert_expansion! macro to unit test macro implementations.

Changed

• Breaking Change Added const generic buffer size to TokenParser.
• Breaking Change Peeker::peek takes &[TokenTree] instead of TokenParser.
• Breaking Change Peeker::LENGTH is function len now.
• Breaking Change *_{delimiter} returns Group instead of the contained stream. To get to the stream call .stream()
• Breaking Change TokenParser::*_{punctuation} got renamed to *_tt_{punctuation} and their behaviour was changed to match that of $tt in macro_rules instead of requiring Spacing::Alone, returned spacing is set to Alone.
• TokenParser peeking supports n greater than stack buffer, allowing spilling to heap.
• Increased default TokenParser peek buffer to 6.
• Marked parser functions as must_use.
• next_expr and next_type set the last tokens spacing to Alone.

Fixed

• Allow assert_tokens in expression position e.g. unbraced match arm

chore: Release proc-macro-utils version 0.6.0

• TokenParser::next_keyword(v)

chore: Release proc-macro-utils version 0.5.2

Fixed

• TokenParser::peek_n() always returned None
• TokenParser::next_{token} did not work correctly because of peek_n

fix: did not consume token

Fixed

• TokenParser::next_string() did not consume token

Added

• TokenParser for parsing simple rust structures
• assert_tokens! macro
• TokenTreeExt::into_<token>() functions
• Delimited trait for accessing TokenTree::Group

Changed

• Breaking Change TokenTreeExt::<token>() now return references

split traits to improve documentation
