ISSOtm 15ec6efc28 Fix missing newline in charmap override warning 2021-01-17 20:13:51 +01:00
ISSOtm 57b734a7df Reinstate RL into the _RS family 
Removal of colon-less labels lifted the grammar ambiguity that
prevented `RL` from being usable as a variable declarator.
Thus, reinstate its functionality.

ISSOtm aa27e714d4 Make Bison version detection more portable 
- POSIX sh actually does NOT support `+=`,
  but Bash does even in compatibility mode
- `mawk` does not fully support POSIX EREs (regexes),
  so work around its lack of brace support
Fixes building on Debian, apparently.

ISSOtm c20ac35074 Refactor readString 
Much more readable, and avoids `peek(nz)`
 2020-12-19 13:02:05 +01:00
ISSOtm 4ef490f3cb Avoid interpreting Liquid in doc pages 
They are auto-generated, so they wouldn't normally contain Liquid
(The post-processor may insert some, but it has control over the `raw` tags)
Some code introduced as examples contains `{{` due to nested brace expansions,
which was interpreted as (invalid) Liquid. This fixes such problems.
Additionally, Jekyll generates warnings about excerpts being part of a Liquid
block (the `{% raw %}`). This is fine, since doc pages don't use excerpts.

ISSOtm 462fd7539c Prohibit nested macros 
After discussion (starting there:
https://github.com/gbdev/rgbds/pull/594#issuecomment-706437458
), it was decided that plain nested macros should not be
allowed.
Since #590 is fixed, EQUS can be used as a workaround;
multiline strings (#589) will make that easier on the
user when implemented.
Fixes #588, supersedes and closes #594.
Additionally, closes #388.

Create specialized symbol finder functions
 2020-11-25 15:17:34 +01:00
ISSOtm 4f842a1248 Create specialized symbol finder functions 
The old "find symbol with auto scope" function is now three:
- One finds the exact name passed to it, skipping any checks
  This is useful e.g. if such checks were already performed.
- One checks that the name is not scoped, and calls the first.
  This is useful for names that cannot be scoped, such as checking for EQUS.
  Doing this instead of the third should improve performance somehwat, since
  this specific case is hit by the lexer each time an identifier is read.
- The last one checks if the name should be expanded (`.loc` → `Glob.loc`),
  and that the local part is not scoped. This is essentially the old function.

New lexer 2 — Electric Boogaloo
 2020-10-04 16:45:47 +02:00
ISSOtm 2eca43cd2d Fix critical oversight in lexer buffer refilling 
Since the lexer buffer wraps, the refilling gets handled in two steps:
First, iff the buffer would wrap, the buffer is refilled until its end.
Then, if more characters are requested, that amount is refilled too.

An important detail is that `read()` may not return as many characters as
requested; for this reason, the first step checks if its `read()` was
"full", and skips the second step otherwise.
This is also where a bug lied.

After a *lot* of trying, I eventually managed to reproduce the bug on an
OpenBSD VM, and after adding a couple of `assert`s in `peekInternal`, this
is what happened, starting at line 724:

0. `lexerState->nbChars` is 0, `lexerState->index` is 19;
1. We end up with `target` = 42, and `writeIndex` = 19;
2. 42 + 19 is greater than `LEXER_BUF_SIZE` (= 42), so the `if` is entered;
3. Within the first `readChars`, **`read` only returns 16 bytes**,
   advancing `writeIndex` to 35 and `target` to 26;
4. Within the second `readChars`, a `read(26)` is issued, overflowing the
   buffer.

The bug should be clear now: **the check at line 750 failed to work!** Why?
Because `readChars` modifies `writeIndex`.
The fix is simply to cache the number of characters expected, and use that.
