Rangi a67f5d6e01 SIZEOF("Section") and STARTOF("Section") can be known
Fixes #890
2021-06-27 21:03:06 +02:00
Rangi 06b57aa1ce Avoid unnecessary "overwriting a non-zero byte" warnings
- Don't warn if the non-zero byte being written is the same as the original byte
- Add a `-O` / `--overwrite` flag to silence all such warnings

Fixes #897

Rangi 80a376f045 Syntax errors resets the lexer right away
`DEF`, `REDEF`, etc disable EQUS expansion, and reading
macro or OPT arguments sets the lexer to raw mode.
Syntax errors resume normal parsing at the line's end,
but should resume normal tokenization even before that.

Rangi 0068c1375c Syntax error message hints to indent macro invocations
This message is only printed for identifiers parsed as
`T_LABEL` (since they're at the start of a line) but
already defined as macros. Otherwise it may not be
relevant, e.g. for `MyLabel;:` or `My Label::`.

Rangi 5ad48851ed Allow error messages for subsequent syntax errors (#892)

ISSOtm e3b7339dd6 Save UNION stack when using PUSHS as well
This allows using the latter within the former
2021-05-21 09:47:27 +02:00
ISSOtm 69d7f84502 Reset LOAD offset when changing SECTIONs
This would cause spurious section overflow messages, since the load offset
is added to the section's when computing its size.

ISSOtm e970b6d6eb Update Zsh completions with CLI changes
Also fix some misc. issues with them, and fix an incorrect reported ID for MBC1

ISSOtm afbaf10185 Fix MBC help string
It's called TIMER, not RTC >_<

Eldred Habert c06985a7ad Fix incorrect lexing of "$ff00+c" (#882)
Fixes #881 by moving the task from the lexer to the parser.
This both alleviates the need for backtracking in the lexer,
removing what is (was) arguably a hack, and causes tokenization
boundaries to be properly respected, fixing the issue mentioned above.

Fixes #538
2021-05-04 15:34:20 +02:00
ISSOtm 1d01268249 Remove LOAD FRAGMENT
It's very troublesome, with flaky semantics and a very restricted use space.

ISSOtm 02cb5a0526 Avoid performing invalid actions on LOAD errors
These are rejected because they could lead to incorrect behavior,
so then don't do it...

Eldred Habert 21b59c4651 Reinstate PUSHS clearing the SECTION scope (#870)
* Reinstate PUSHS clearing the SECTION scope

Otherwise you can use `PUSHS` to simulate the old `ds -21`, and possibly cause bugs

* Have PUSHS push LOAD block state as well

It does not make sense not to, and coud cause bugs.

GreenAndEievui b4814b06b9 Updated RGBFIX to report when non-zero bytes are overwritten
Also updated many .err files with the new warning.

Rangi 4ee2eb845b Clone test repositories with earlier --shallow-since dates
The previous dates were not reliably downloading the
necessary commit IDs for checkout to work.

Rangi 43cf20b155 Support Mac OS classic CR line endings in linkerscripts
This also refactors `readChar(file)` to `nextChar()` to be
more like the rgbasm lexer.
2021-04-26 12:05:36 -04:00
Rangi e27a6d53a0 Support character escapes in linkerscript strings
This allows linkerscripts to refer to section names even if
they contain special characters: '\r' '\n' '\t' '"' '\\'.

Rangi d17e9c663e Update the tested commits of pokecrystal, pokered, and ucity (#859)
These are the latest commits as of today. The pokecrystal and
pokered commits use rgbds 0.5.0 features; ucity does not but
is compatible with it.

Rangi 27f38770d4 Parentheses in macro args prevent commas from starting new arguments
This is similar to C's behavior, and convenient for passing
function calls as single values, like `MUL(3.0, 4.0)` or
`STRSUB("str", 2, 1)`.

Fixes #704

Rangi 4d21588eb2 Make invalid UTF-8 characters in strings non-fatal
STRLEN and STRSUB report the erroneous bytes

Fixes #848
2021-04-22 09:59:02 +02:00
Rangi e596dbfc80 Make failed macro arg expansions non-fatal
Expanding empty strings is valid but pointless;
macro args already skipped doing so, now other
`beginExpansion` calls do too.

This also fixes failed interpolations (which were
already non-fatal) to continue reading characters,
not evaluate to their initial '{' character.

Rangi 1aeaca2af6 Add test case sort-algorithms.asm
This combines 0.5.0 and post-0.5.0 features:
print and println, strfmt, for loops,
def assignments, redef equs, {interpolation},
new macro syntax, and \<bracketed macro args>
2021-04-20 22:36:56 -04:00
Rangi fe3521c7a4 Switch from parentheses to angle brackets
`\(` is more likely to be a valid escape sequence in the
future (as is `\[`) and `\{` is already taken.

For example, \(_NARG) will get the last argument

Rangi 637bbbdf43 Support multi-digit macro arguments in parentheses
This allows access to arguments past \9 without using 'shift'

Rangi cf2bbe6435 Position -1 is the last character of a string
Position 0 is invalid, which matches with STRIN/STRRIN
returning 0 on failure.

Rangi dc5b7802c8 Make the len parameter optional in STRSUB(str, pos, len)
An unspecified length will continue to the end of the string.
2021-04-20 14:27:59 +02:00
Rangi b1e6c73197 STRSUB and CHARSUB allow zero or negative positions
These are offsets from the end of the string, as if the
STRLEN or CHARLEN respectively were added to the position.

Rangi d43408f4f3 Allow OPT to modify -W
Warning flags are processed individually;
PUSHO and POPO (re)store all the warning states.
2021-04-18 00:11:18 +02:00
Rangi 2c30ab8731 Allow OPT to modify -L
-L is a Boolean flag option, so you specify 'OPT L' or 'OPT !L'.

Rangi 9923fa3eee Fix expansions that start from the end of another expansion (#839)
Do not free an expansion until its offset is *past* its size.
This means potentially freeing a nested stack of expansions
all at once.

Rangi ee5da4468d Fix interpolation/STRFMT overflow issues (#838)
Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.

Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

Rangi c755fa3469 readIdentifier does not process characters that get truncated
Previously a '.' could be past the truncation limit but still
cause the identifier to be marked as local, violating an
assertion in `sym_AddLocalLabel`.
