[Bug #21186] multibyte char literal should be a single letter word
2024-08-06parse.y: const_decl_path don't replace destination node by a literal (#11314)Jean byroot Boussier
[Bug #20668] The `dest` node is assumed to be a `CDECL`, so overwriting it with a `LIT` cause a crash on the next iteration. Co-authored-by: Jean Boussier <jean.boussier@gmail.com>

2023-10-31Keep unused literal nodesyui-knk
For static analysis, it’s better to keep unused literal nodes. If simply change `block_append` to fall through, both "unused literal ignored" and "possibly useless use of a literal in void context" warnings are shown for the same line. But it’s verbose then remove "unused literal ignored" warning. This kind of optimization is already implemented on compile.c. `compile_block` calls `iseq_compile_each0` with `popped = 1` when NODE_BLOCK has next.

2023-10-13[Bug #19924] Source code should be unsigned char streamNobuyoshi Nakada
Use `peekc` or `nextc` to fetch the next character, instead of reading from `lex.pcur` directly, for compilers that plain char is signed.

2023-06-30Handle unterminated unicode escapes in regexpsJeremy Evans
This fixes an infinite loop possible after ec3542229b29ec93062e9d90e877ea29d3c19472. For \u{} escapes in regexps, skip validation in the parser, and rely on the regexp code to handle validation. This is necessary so that invalid unicode escapes in comments in extended regexps are allowed.

2021-07-21Fix interpolated heredoceileencodes
This fixes https://bugs.ruby-lang.org/issues/18038. The provided reproduction showed that this happens in heredocs with double interpolation. In this case `DSTR` was getting returned but needs to be convered to a `EVSTR` which is what is returned by the function. There may be an additional bug here that we weren't able to produce. It seems odd that `STR` returns `DSTR` while everything else should return `EVSTR` since the function is `new_evstr`.
