TODO:

- NaN in cycle count for macros
- debugging of scan line overflow
- confuse code/data in listing
- show memory locations hovering over lines
- don't check against ROM signatures
- support 6502 test cases
- DASM: macro forward refs
- asm: support macro expansion
- support narrow screens
- case sensisitvity looking for mismatch variables
- remove pulldown when no preset?
- can't step after reset (or when funky frame; TIA frame is out of sync)
- break on BRK/illegal opcode?
- multiple breakpoints, expression breakpoints
- watchpoints
- breakpoints
- debug inspector
- MAME single step (?)
- step over (line, instruction)
- slowdown beam for all platforms?
- PC x86 support
- show errors in list (maybe window list?)
- can't see 1st line in editor sometimes (when scrolling cursor past bottom of screen)
- online help
- show self-modifying code insns left of editor
- facade/kbd shortcuts for emulators, focus
- update Javatari version? (and others?)
- unify versioning
- disassembler for uploaded ROMs
- verilog debugging/reloading makes it slow
- remove FPS and play controls when Verilog scope paused
- compile stuck when errors unchanged
- sound mute?
- $error updates source editor
- go to error in include files
- online tools for music etc
- text log debugging script
- NES crt should mark raster pos when debugging
- intro/help text for each platform (+ memory map)
- vscode/atom extension?
- navigator.getGamepads
- VCS library
- better VCS single stepping, maybe also listings
- VCS skips step on lsr/lsr after run to line
- bring back the profiler!
- links to external tools in ide
- error msg when #link doesn't work
- figure out folders for projects for real
- why loadState() on verilog kill perf?
- click to break on raster position
- restructure src/ folders
- quantify verilog "graph iterations"
- debug bankswitching for funky formats
- spaces in filename don't parse code listing (DASM, maybe more)
- zmac: item_lookup needs better hash function
- 'undefined' for bitmap replacer
- astrocade: run to cursor in hello world messes up emulation
- requestInterrupt needs to be disabled after breakpoint?
- verilog: when paused scope doesn't work
- C/asm formatter
- fix WebAudio (https://news.ycombinator.com/item?id=18066474)
- share playable link w/ verilog?
- allow download of JSASM output
- update bootstrap
- $readmemb/h
- batariBasic: proper line numbers, debugging
- show player controls for each platform, allow touch support
- granular control over time scrubbing, show CPU state
- error showing replay div before rom starts
- compiler flags for final ROM build
- workermain: split build functions, better msg types
- vcs: INPTx needs to be added to control state
- rename, delete, save as
- sdcc: can't link asm files before c files (e.g. acheader.s must be last)
- what if >1 file with same name? (local/nonlocal/directory)
- what if .c and .s names collide?
- live coding URL
- memory viewer: ROM/RAM/VRAM/etc
- resize memory browser when split resize (any div resize)
- preroll the emulator so optimizer does its thing before loading rom
- wasm dynamic linking of emulators (https://github.com/WebAssembly/tool-conventions/blob/master/DynamicLinking.md)
- use alternate confirm/prompt dialogs
- https://github.com/jvilk/BrowserFS
- what if error in include file you can't edit b/c it never appears?


WEB WORKER FORMAT

{code,platform,tool,dependencies}
{preload}

new:

{updates,buildsteps}
[{filepath,platform,tool}]

implicit rules
- push/shift build steps
- preprocessor, compile, assemble, link
- access to intermediate files

only build files that have changed

build options


BUILD PROJECT

local/foo.project/*.*
build all files in project
send update for dependencies at startup (single file version)
should be able to change file w/o reloading (Not platform tho)

pulldown selects file in project, or goes back to parent
gotta preserve editor windows for each one - window list
make source/disasm window visible when debugging
gutter info/errors in all files



UI REFACTOR

editor
debugger
disasm view
memory
profile
errors

separate into files

window methods:
- set
- mode
- get
- changes
- cursorActivity (inspect)
- gutters (setCompileOutput)
- current line / gutter marker (setCurrentLine / clearCurrentLine)
- source map
- global symbols
- pixel editor / find comment (openBitmapEditorAtCursor)
- update debug window (200 ms)
- inspect variable

file store mirrors that on worker

worker result:
{
	output:<rom>
	sources:{
		<path>:{lines, asmlines, listing}
	}
}

add file to errors

PIXEL EDITOR

everything is an editor
back/forward propogation
encoded <-> raw + spec + palette(s) <-> full tilemap <-> selected tile/sprite/metasprite
