Rangi c7a92d3104 rgblink -M omits symbol names from .map file 2022-08-28 20:35:21 +02:00
Rangi 4ed5ba7508 Finish using time_utc before initializing time_local 
gmtime and localtime may share the same static internal struct tm,
so they cannot both be initialized and then used.
 2022-01-27 22:32:34 -05:00
Rangi 20a26599a3 Simplify allocating multiple ds args 
Dealing with indexes is only necessary for `strfmt`
 2021-12-01 20:24:31 -05:00
Rangi 7bdfc9da23 Really don't use new as a variable name 2021-11-30 17:06:36 -05:00
Rangi d073cffa74 Don't use new as a variable name 
It conflicts with the C++ keyword
 2021-11-24 22:48:28 -05:00
Rangi 8435a29c4e Turn the readChars macro into a readInternal function 
This macro was only used twice, and the second usage did
some unnecessary work.
 2021-11-25 00:26:23 +01:00
Rangi 9d993d84e8 Release 0.5.2 2021-11-23 17:08:03 -05:00
Rangi db79689e81 Add -Wnumeric-string to shell autocompletion 2021-11-22 17:58:12 -05:00
Rangi c2ca46c27d Remove TRACE_PARSER support 
Attempting to build with this gave an "undefined reference to `yydebug'"
error (maybe a version issue with bison?), and I don't think it's been
used for recent parser debugging either.
 2021-11-22 23:49:59 +01:00
Rangi aac839f389 Remove dbgPrint and TRACE_LEXER support 
I have not found `TRACE_LEXER` to be useful in debugging
actual lexer issues.
 2021-11-22 23:49:59 +01:00
Rangi 9d9febe1d3 Consistent title case for rgbasm.5 headings 2021-11-22 17:12:16 -05:00

Rangi 036b6c1b89 Capitalize "FATAL:" in rgblink error messages 
"warning:" and "error:" are lowercase
This matches rgbasm's formatting
 2021-11-19 19:52:57 -05:00
Rangi 8e2a164a32 Implement compound assignment operators for mutable constants 
Fixes #943
 2021-11-19 08:50:00 +01:00
Rangi b76819792d Deprecate SET in favor of = 
`SET` is redundant with `=`, and is already the name of an instruction.
 2021-11-19 00:05:49 +01:00
Rangi 3e945679ad Standardize on "east const" (type const * not const type *) 
Avoid "WARNING: Move const after static - use 'static const char'"
 2021-11-18 09:12:00 +01:00
Rangi efccf6c931 A few stylistic tweaks 
- `goto free_romx` -> the more typical `goto cleanup`
- `goto fail` -> the more typical `goto finish`
- Remove a redundant `todo` variable
 2021-11-17 23:51:40 -05:00
Rangi e5552e27f2 strrstr can take and return char const * 2021-11-17 22:47:05 -05:00
Rangi b002d95459 Fix precison of fixed-point formatting 
Fixes #908
 2021-10-28 23:29:16 +02:00
Rangi 4a73eb56ea Make peek() tail recursive instead of using goto 
Compilation is identical with `gcc` or `clang`, -O3` or `-O2`
 2021-08-18 01:30:47 +02:00
Rangi b51e1c7c2c Compare FOR ranges to Python's range 2021-08-01 10:45:44 +02:00
Rangi 26ddf1ff4d Prevent defining invalid local labels 
Fixes #913
 2021-07-30 15:21:47 +02:00
Rangi 03bb510588 endCapture shouldn't handle lexerState->atLineStart 
`startCapture` did not initialize `lexerState->atLineStart`;
its final value is a consequence of the separate but similar
behaviors within `lexer_CaptureRept` and `lexer_CaptureMacroBody`.
 2021-07-04 18:31:46 -04:00
Rangi 695dfe9dbd Add missing file line-continuation-string.asm 
Also make some minor formatting corrections
 2021-07-04 16:12:34 -04:00
Rangi 1b5648bb06 Line continuations *do* work inside strings 
The rgbasm.5(5) documentation was outdated here
 2021-07-01 17:56:49 -04:00
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
 2021-06-27 19:16:11 +02:00
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.
 2021-05-22 16:08:55 -04:00
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::`.
 2021-05-22 14:58:26 +02:00
Rangi 23721694ea Comment that anonymous labels internally start with '!' 
`startsIdentifier` should not accept this character so
anonymous labels won't conflict with nonymous ones.
 2021-05-15 12:57:22 -04:00
Rangi 6a5e2f439e Fix the STRFMT documentation in rgbasm(5) 
Fixes #886
 2021-05-09 17:23:57 -04:00
Rangi fba77c4dce Specify to update the release branch in RELEASE.rst 
This is done manually after publishing a release.
 2021-05-08 23:44:53 -04:00
Rangi 830df360ae Specify that all .sh files need Unix line endings 
The `git config --global --unset core.autocrlf` command
was failing in the "Create release artifacts" workflow,
so this is an alternate method of fixing issue #841.
 2021-05-08 23:22:31 -04:00
Rangi c75551b1b3 Release 0.5.1 2021-05-08 22:38:20 -04:00
Rangi 5a38f6e148 rgbasm supports "Q16.16" fixed-point literals 
"Qm.n" signifies an m-bit two's complement integer
with n fractional bits.
<https://en.wikipedia.org/wiki/Q_(number_format)>
 2021-05-06 23:17:08 -04:00
Rangi 869021f47d Fix -Wformat build warnings on macOS 
C arithmetic promotes certain expressions to `int`,
so formatting has to use "%d" or "%x", not inttypes.h.

Fixes #883
 2021-05-04 21:28:57 -04:00
Rangi 8397b3d8ec .sym file sorts symbols from zero-length sections first 
This will, for instance, ensure that a zero-length
`SECTION "NULL", ROM0[0] / NULL::` comes first.
 2021-05-02 17:57:20 -04:00
Rangi 296e5489c9 rgblink adjusts patches' PC offsets when merging FRAGMENTs 
Fixes #869
 2021-05-02 23:54:42 +02:00
Rangi 9ab9d0f39c Output all SECTION UNION/FRAGMENT symbols in .sym files 
Fixes #809
 2021-05-02 23:51:17 +02:00
Rangi e9bfe849ad Allow OPT to toggle -h 2021-05-02 11:06:53 +02:00
Rangi 665eb916a2 OPT L acts like -L and *dis*ables optimizing LD to LDH 
Fixes #867
 2021-05-02 11:06:53 +02:00
Rangi 04788e15af Fix a potential out-of-bounds array access in RGBGFX 
This was caught by ASAN for pokered's gfx/battle/minimize.png.
 2021-05-01 22:33:54 -04:00
Rangi ca36422ac9 Parse 'ld hl, sp - <e8>' correctly 
Fixes #864
 2021-05-01 11:08:01 +02:00
Rangi 8e4ba8d2e4 Allow REDEF for EQU constants 
Fixes #853
 2021-04-29 12:24:07 +02:00
Rangi ee67f1039c Fix REDEF EQUS behavior 
Redefining an EQUS constant will now update its filename,
like redefining a SET/= constant.

Attempting to redefine as EQUS a non-EQUS constant will
print an appropriate error message.

This also standardizes on `sym` versus `symbol` as a
variable name (which pairs with `symName`).
 2021-04-28 12:11:26 -04:00
Rangi d37aa93a7d Port some cleanup from the WIP 'strings' branch 
This is mostly variable renaming
 2021-04-28 11:58:56 -04:00
Rangi bba532193b Port some cleanup from PR #847 
- Update some whitespace formatting
- Factor out some functions
- Free data after outputting to an object file
 2021-04-28 11:58:56 -04:00
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.
 2021-04-27 17:27:23 -04:00
Rangi 3fdf01c0f5 Resolve some TODO comments 
- `out_PushSection` should not set `currentSection` to NULL because
  PUSHS, PUSHC, and PUSHO consistently keep the current section,
  charmap, and options, even though the stack has been pushed.

- `Callback__FILE__` does not need to assert that `fileName` is not
  empty because `__FILE__`'s value is quoted, and can safely be empty.

- `YY_FATAL_ERROR` and `YYLMAX` are not needed since the lexer is
  not generated with flex.
 2021-04-26 15:52:30 -04:00
Rangi 1949a61c6f Tested the ctz and clz shim functions 
Their values match the GCC builtins for all
4,294,967,295 nonzero inputs.
 2021-04-26 12:17:34 -04:00
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' '"' '\\'.
 2021-04-26 12:05:36 -04:00
Rangi e050803ed1 Use size_t for measuring nested depths 
Multiple functions involve tracking the current depth
of a nested structure (symbol expansions, interpolations,
REPT/FOR blocks, parentheses).
 2021-04-23 14:28:10 +02:00
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
 2021-04-23 14:28:10 +02:00
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.
 2021-04-22 09:59:02 +02:00
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
