These are all general issues with the pokecrystal code. Keep an eye out for opportunities to refactor them.

Use the style guide

Reformat code to adhere to STYLE.md. (Converting labels to .snake_case is one that stands out.)

Take advantage of up-to-date rgbds features

As of 0.3.7, we have these features that are little-used:

  • ~ works for bytes, so we can do ~X instead of $ff ^ X
  • HIGH() and LOW() work for constants
  • BANK(@) gets the current bank; BANK("Section Name") is also valid (some labels can thus be removed)
  • \ continues lines, like in C or Python, which could help clean up long macros (trainer, npctrade) and implement new ones (like for data/trainers/attributes.asm or data/pokemon/base_stats/*.asm)

Meaningless temporary labels

Look for UnknownText_*, UnknownScript_*, Unknown_*, and Function_*.

Hard-coded "magic numbers"

Most of the time, raw numbers should not exist because there are more meaningful replacements. Examples:

  • BANK(Label): Mostly finished for WRAM labels, but still a problem with mobile code.
  • SomeLabelEnd - SomeLabel: Some structs and sub-structs still have hard-coded sizes like this.
  • (SomeGFXLabel.End - SomeGFXLabel) / LEN_2BPP_TILE: pokered and pokegold-spaceworld already do this.
  • Bit flags: Use SOME_BIT_F constants instead of hard-coding bits 0-7 for the bit/res/set instructions. Find opportunities with: grep -rE --include='*.asm' --exclude-dir=mobile '^\s(bit|res|set) [0-7],'
  • Bit masks: Use 1 << SOME_BIT_F masks and the maskbits macro.
  • Jumptable indexes: Look for raw values being loaded into [wJumptableIndex].

Text label styles in data/text/

Currently a mixture of Text_*, *Text, and BattleText_*. Likewise for the engine/ labels that just text_jump to one of them.

The convention that should be used is as follows:

  • Use suffixes, i.e. not Text_Something, but SomethingText. Same for Movement.
  • Labels that are referenced through text_jump should be prefixed with an underscore, e.g. SomethingText: text_jump _SomethingText.

WRAM label style

  • wMapObjects and friends to be re-formatted to wObjectEvents
  • wObjectStructs and friends to be re-formatted to wMapObjects
  • Removal of struct macros which include only a partial label definition (e.g. wNorthMapConnection:: map_connection_struct wNorth)

Project structure

  • Split big files into meaningful parts
  • Give files meaningful names
  • Remove redundancy in names such as thing/thing_subthing.asmthing/subthing.asm
  • Move files into their proper directories:
    • Palettes in gfx/
    • Pointer tables in data/
  • Group related things in meaningful directories.

Future of SECTIONs

Namely determining the purpose of them and when they should be defined.
