v0.9.0-rc2

Tip

Starting with this release, we publish universal ("fat") binaries for macOS, so they'll support x86-64 and newer ARM (“Apple Silicon”) CPUs!

⚠️ Deprecated

• Treating multi-character strings as numbers (you can use a single 32-bit character mapping instead)

Added

• RGBASM -s outputs a "state file", listing the values of (non-label) symbols when finished assembling
• RGBASM -Wpurge warns when purging exported symbols or labels

• Symbols can have the same names as reserved keywords by prefixing them with a #
• CHARMAP can map characters to sequences of multiple values, with values not limited to 8 bits
• A string constant . (period) which expands to the current global label scope
• A string constant .. (two periods) which expands to the current fully-qualified local label scope (e.g. Global.local)
• 0x, 0b, and 0o prefixes for hex, binary, and octal numbers (in addition to $, %, and &)
• BITWIDTH(n) returns the number of bits necessary to represent n
• TZCOUNT(n) returns the count of trailing zero bits of n

• ENDL is explicitly optional, but with an opt-in -Wunterminated-load warning about it
• cpl can also be written as cpl a
• Allow a no- prefix to negate "meta" warnings (-Wno-all, -Wno-extra, -Wno-everything)
• Allow -Wno-error=... to override -Werror (including for "meta" warnings)
• RGBLINK supports e.g. ROMX FLOATING in linker scripts, which allows assigning a section to no particular bank (this is generally only useful with SDCC object files)
• RGBLINK's .sym file now includes exported numeric constants (if this breaks your tools, please check the .sym specification!)
• RGBGFX -i/--input-tileset uses a given tileset instead of generating all the tiles itself
• RGBGFX -r 0 infers a valid width for the reversed image
• RGBGFX -X or -Y only mirror tiles horizontally or vertically (-X -Y acts like -m)
• The contrib/view_palettes.sh script lets you render a GBC .pal file as an image

Changed

• Macro invocations can be at column 1, the very start of a line
• LOW(Label) can be constant if Label is aligned to 8 or more bits
• !expr can be constant 0 if expr has any non-zero bits
• Error messages for undefined symbols mention if the symbol was previously purged
• Sections that grew too big are reported after the whole assembly file has been processed
• When RGBLINK encounters an unknown symbol, it lists the potential un-exported symbols by that name
• RGBLINK reports source locations for conflicts between object files
• RGBGFX -r gives a detailed warning if -c and -p mismatch; improved several other error messages too
• LOW() and HIGH() have their own RPN operators in the object file (this should lead to nicer output from rgbobj)
• Clarified a lot of documentation, including for fixed-point numbers and macros
• Explicitly document that FMOD behaves differently than %

v0.8.0

Happy Pride month! 🏳️‍🌈

This release internally refactored a lot of C code into more idiomatic C++ (partly to fix memory leaks), which *hopefully, knock on wood, fingers crossed* won't have broken anything else.

We're optimistic that the next release will be a 1.0.0 rewritten in Rust. 🦀

Added:

• RGBGFX allows #none as a "gap color" in -c palettes (thanks, @eievui5!)
• RGBFIX -L/--logo can specify a custom logo 1bpp instead of the Nintendo logo
• RGBASM allows "\0" as a NUL character in strings
• RGBASM align 16, N acts like org N (so align 16 acts like org 0)
• RGBLINK -p padding applies when output goes past the -O overlay file contents

Removed:

• Defining symbols without using DEF
• RGBASM -H/--nop-after-halt, -l/-auto-ldh, -h/--halt-without-nop, and -L/--preserve-ld options (the auto-ld-to-ldh and auto-nop-after-halt behaviors are now completely removed)
• RGBASM -i for --include (use -I)
• RGBGFX --output-* long options (use --auto-* or the short -A/-P/-Q/-T options)

Changed:

• Strings and symbol names are no longer limited to 255 characters!
• expr && 0 and expr & 0 are constant 0; expr || 1 is constant 1
• All warnings/errors refer to input/output file "-" as "<stdin>/<stdout>"
• Documentation switched from reStructuredText to Markdown for ease of contributing

Fixed:

• Increment object file revision number to 10 (since 0.7.0 updated the object file format but didn't increment this)
• Linker scripts infinitely looped when parsing decimal numbers (thanks, @huderlem!)
• Long RGBASM interpolation format specs could segfault
• RGBGFX --reverse --columns was incorrect for non-square images (thanks, @sfiera!)!!!!
• ACO palette files were not being read correctly
• Specifying an embedded palette to override a previously specified palette crashed (thanks, @ZoomTen!)
• Warning/error file-stack traces for macros inside REPT/FOR loops are complete
• Building RGBDS nested in another Git repo won't pick up that repo's tags for the RGBDS version
• Some fixed-point functions could give inconsistent results if they internally gave infinity or NaN (e.g. FMOD(value, 0.0))
• Formatting $8000_0000 (-2,147,483,648) as a string was omitting the negative sign
• BANK(NotALabel) is 1, not $4B4E4142 (the numeric value of "BANK" 😂)
• \@ could change within a macro or REPT/FOR if it was first used within an INCLUDE
• Some built-in symbols could be misreported as being defined on the command-line

v0.7.0

Starting with this release, we publish statically-linked Linux binaries! We also provide a Dockerfile to build RGBDS.

Deprecated:

• Defining symbols without using DEF (use {interpolation} if you relied on EQUS expansion for defined symbol names)
• RGBASM -H/--nop-after-halt and -l/-auto-ldh options (which are now off by default)

Added:

• Multiple instructions can go on one line, separated by ::
• #"raw strings" don't process any escapes (not even interpolation or macro args!)
• DS ALIGN[size, offset] to insert padding until the next alignment boundary within the same section
• RGBASM allows defining local labels for scopes that aren't active
• INCHARMAP function to check if a string matches a charmap value
• SIZEOF and STARTOF can now take section types like WRAM0 as argument
• ENDSECTION explicitly ends a section
• DS in RGBLINK linker scripts
• OPTIONAL sections in RGBLINK linker scripts
• FLOATING addresses in RGBLINK linker scripts (should improve SDCC interop)
• RGBASM -X/--max-errors stops after too many errors, with a default of 100
• Linker scripts support ALIGN alignment, offset
• RGBFIX warns when SGB compatibility is set with the wrong "old licensee", even if not setting it via RGBFIX itself
• RGBGFX can generate a palette from a spec, without an input image
• RGBGFX forces transparent colors to take slot #0 in all palettes
• RGBGFX -O/--group-outputs bases automatic output filenames on the output path, instead of the input path

Removed:

• name: MACRO syntax (use MACRO name instead)
• Escaped commas "\," inside strings (not necessary in macro arguments)
• __FILE__ and __LINE__
• Exported labels cannot have a space between their two colons (Label: : is invalid)

Changed:

• RGBASM -Wtruncation=1 will not warn about 8-bit ~$FF or 16-bit ~$FFFF values
• The memory usage summary in .map files is now placed at the top of the file
• Alignment offsets in RGBASM can now be negative (ALIGN 8, -1 is equivalent to ALIGN 8, 255)
• RGBGFX's --output-* options have been renamed to --auto-* for clarity
• RGBLINK .sym files sort symbols at the same address by their locality
• RGBLINK -S/--scramble prioritizes higher banks
• RGBGFX's long --output-* flags are renamed to --auto-*
• All programs show usage help when given missing or incorrect command-line arguments
• Add --only-free and --help options to test scripts
• PURGE arguments can go in any order

Fixed:

• RGBASM preserves the value of \@ through INCLUDEd files
• FOR loops, in some edge cases, could loop with unexpected values
• PUSHO and POPO now save and restore the r option
• ENDL now restores the label scope from before LOAD
• Anonymous labels are never exported anymore, as doing so could cause link errors
• -1 >>> 32 now equals 0, not -1
• Document ATAN2 to have argument order (y, x)
• RGBLINK's -w flag properly coerces WRAMX sections to WRAM0
• Fix off-by-one error in RGBLINK -S/--scramble argument validation
• RGBGFX could crash on some images with alpha transparency
• RGBGFX --color-curve now works as it always should have
• RGBGFX properly detects tiles with more than 4 colors
• RGBGFX -r/--reverse gave incorrect output with -d/--depth 1
• RGBGFX ignored -L/--slice if -u/--unique-tiles wasn't also passed
• RGBGFX ignored -c/--colors with -r/--reverse
• RGBGFX outputs a palette map to the right filename
• Fix formatting errors in documentation
• Fix incorrect options in RGBGFX zsh completions
• Made testing scripts a little more robust

v0.6.1

Starting with this release, we now publish macOS binaries!

Added:

• RGBASM prints a specific error message for leftover diff marks (+ and -)
• RGBLINK has improved .map file output:
  • EMPTY blocks have address ranges, and fixed indentation and duplicates
  • ; Next union/fragment comments have fixed indentation and placement
• RGBGFX supports - for stdin and stdout

Fixed:

• RGBGFX terminates if opening a file fails
• Fix some possible build errors on some systems
• RGBLINK could crash when merging SECTION FRAGMENTs that aren't in ROM
• RGBLINK mangles absolute SECTION names to support SDCC "areas"
• RGBGFX could crash on empty palette slots with "Assertion 'this->_M_is_engaged()' failed."; we hardened our test configuration to catch more bugs like this

A big thank you to @eievui5 and @pinobatch for additional testing during the development of this version, as well as @rlewicki for some improvements to the codebase!

v0.6.0

Our website received a big facelift, please check it out at https://rgbds.gbdev.io! Thanks to @ISSOtm and @avivace for the work on this.
While some pages have been moved around, all URLs under /docs have been preserved.

Deprecated:

• m: MACRO syntax; use MACRO m.
• __FILE__ and __LINE__.
• rgbasm -h and -L will soon become the default behavior; please use rgbasm -H and -l respectively to opt into the current behavior.
• rgbgfx -h has been renamed to the less confusing rgbgfx -Z.

Added:

• RGBGFX has been massively overhauled! Please check out the new docs for full details, but notably:
  • The alpha channel is now handled in a sensible and useful way.
  • Palettes can be manually specified without having to muck with PNG embedded palettes using -c!
  • rgbgfx -r can also "reverse" the process and generate a PNG from the binary data.
  • "At-files" allow storing the flags e.g. next to the image, instead of centralized within your Makefile/build script.
  • State-of-the-art packing algorithm ensures optimal palette generation 😎
  • Special thanks to @aaaaaa123456789 for randtilegen, used for testing; @eievui5, @MarkSixtyFour, and @Rangi42 for review and testing!
  • There's an egg somewhere in there?
• Unsigned right shift operator >>>!
• Binary AND & can now be constant if applied to a symbol with the right alignment.
• rgbasm -Q or OPT Q configures the fixed-point precision, which is still 16 by default (e.g. -Q8 uses Q24.8).
• FMOD function for fixed-point modulo.
• Precise fixed-point literals like 12.34q8 override the current Q option value.
• Fixed-point functions take an optional final argument to specify their precision, overriding the current -Q option.
• @ and _NARG are considered undefined (e.g. by DEF) when they have no value.
• rgbasm -P allows automatically pre-including a file before the source file; for example, to define constants used throughout the codebase.
• SECTION(symbol) evaluates to the name of symbol's section.
• rgbasm -r sets the maximum recursion depth, not the minimum failure depth (off by one).
• OPT r.
• -Wunmapped-char=0/1/2 warning for characters not in the charmap. Level 1 ignores unmapped characters in a non-default charmap if it's empty, level 2 does not.
• \@ only increments its expanded value when used, so merely adding or removing MACRO, REPT, or FOR blocks will not affect generated symbols.
• RGBASM will warn if a command-line argument overrides a previous one, for example -o.
• RGBLINK is able to link SDCC object files.
• RGBLINK will now report floating sections' names when using -O.
• RGBLINK will omit symbol names from the .map file when using -M.
• RGBLINK will not output anonymous labels in the .sym file, to comply with the spec.
• RGBLINK will report EMPTY space between sections in the .map file, and total used+empty space at the end.

Removed:

• PRINTT, PRINTI, PRINTV, PRINTF (use PRINT/PRINTLN instead)
• _PI
• SET as an assignment operator (use = instead)
• rgbgfx -D, -f, and -F were not useful anymore

Changed:

• RGBASM trigonometry functions now divide a circle into 1.0 turns, not 65536.0 so-called "binary degrees".
• Please prefer rgbasm -I over rgbasm -i, for consistency with other tools (mainly C compilers); -i will be phased out in a future release.
• man pages are now all in a single directory; this affects the release tarballs!
• .map files now have a more useful free/used space summary at the end
• .map files are now indented using tabs (requested in #1012)

Fixed:

• rgblink -S rejected a lot of valid arguments.
• rgblink -O could "forget" ROM0 if no such sections were defined, offsetting the entire file.
• Whitespace is now trimmed in macro arguments, even after line continuations.
• All *UTC* symbols could contain local time instead on some systems.
• contrib/gbdiff.bash correctly handles spaces in its arguments (oops)
• Version number will always be properly updated when building with CMake.
• RGBASM now warns when specifying options that override eachother.
• rgbasm -b and -g were broken.

v0.6.0-welease-cnyandidayte

April Fools! Please do not use this release for anything serious, it's wildly incompatible—just a joke..!

We understand that assembly is a fairly dry and old-school language. We understand that it does not necessarily appeal to the modern programmer (and their socks) anymore.

Therefore, we have decided to experiment and shake up the instruction syntax a little bit. UTF-8 characters are now accepted as input, a handful of instructions have been renamed—as have been the registers, and more! 👀 We invite you to check out the new documentation for the full list of changes~

Pwease be warned that the new syntax is a teeny tiny bit expewimental, and so any ewwows should be wepowted to youw neawest /dev/null! ^w^

🐈

v0.5.2

Deprecated:

• SET for mutable definitions is deprecated; use =

Added:

• Bash completion scripts for rgbasm, rgblink, rgbfix, and rgbgfx!
• RGBFIX won't warn when overwriting a byte with the same value
• rgbfix -O to silence all "overwriting non-zero byte" warnings
• rgblink -S "scrambles" bank assignments to help find broken assumptions in your code
• Unindented macro invocations will be hinted at when encountered
• -Wnumeric-string=0|1|2 warns about use of strings as numbers
• Compound assignment for variables (e.g. DEF x += 1 for DEF x = x + 1)
• ! negates condition codes z/nz/c/nc
• Allow _ in gfx literals, e.g. `0123_3210

Updated:

• Zsh completions synced with RGBDS changes
• rgbfix -m MBC3+TIMER implies BATTERY, warning if not specified
• Symbol interpolation is now more prominently described
• -Wtruncation can be made less strict; use -Wtruncation=1 for more lax behavior

Fixed:

• rgbfix -m MBC3+TIMER+BATTERY didn't work
• LOAD offset wasn't reset when switching sections
• PUSHS inside UNION should work as expected
• Syntax errors after the first one were silenced
• Some syntax errors could break parsing
• Some invalid local labels could be defined
