Rangi 55db252a8f Simplify the lexer by removing BufferedContent and inlining ViewedContent (#1981)
Instead of reading 64 characters at a time into a rolling buffer
as `shiftChar()` is called, we read 8192 characters at a time into
a complete buffer before any `peek()`/`shiftChar()` operations.

Rangi 4a173130b9 Optimize skipToLeadingKeyword for the common ViewedContent case (#1968) 2026-05-22 19:06:12 -04:00
Rangi ef2f021892 Simplify sectError handling, without the need for an empty-string sentinel
The `errorNoTrace` case for the empty-string sentinel was unreachable,
so we can just have a `fatalNoTrace` error right away.

Rangi dce14fd4b8 Use C++20 concepts to require constraints on template parameters (#1977) 2026-05-22 17:54:34 -04:00
Rangi 728bed39d5 Do not support GCC 9 (#1978)
This will let us use C++20 features that GCC 9's experimental
C++20 support did not yet cover, such as "concepts".

- Add more `assume()` checks in the lexer
- Replace double negative "`disable* = false`" with "`enable* = true`"
- Naming convention of "`std::deque<> *Stack`" when relying on
  `.push_front()` and `.pop_back()`

Rangi42 9fd0c0297f Fix invalid character in bracketed macro argument

Rangi cfec017fed Consolidate, refactor, and bugfix the lexer's handling of captures and skips (#1957)
- Do not error about local labels following keywords in skips or captures (fixes #1955)
- Do not incompletely attempt to handle line continuations in skips (fixes #1956)
- Rename `skipToLeadingIdentifier` to `skipToLeadingKeyword`, refactor to merge
  `skipToEOL` into it, and use it for both skips and captures

Rangi 20b11039c9 Keep trie edges sorted for O(log N) lookup 2026-04-17 15:39:30 -04:00
Rangi eb9e9c0f33 Replace charmaps' fixed-size 256-value array with a vector of pairs
This should save memory at the cost of O(n) instead of O(1) access,
which should be okay because the `next` vector is generally small.

that have precision suffixes.

Rangi ede9405daf Fix some fixed-point literal lexing issues (#1914)
- No fractional digits are necessary after the decimal point,
  e.g. `42.` is valid instead of `42.0`
- Error messages refer to "fixed-point" not "integer" constants
- Test more carefully for lexing unrelated to underscores
