Padauk Mini-C for VS Code
Syntax highlighting for Padauk Mini-C, the C-like language used by the Padauk
FPPA toolchain (PMS / PMC / PFS / PFC / PDK microcontrollers).
What it highlights
| Construct |
Example |
| Compile-time directives |
.define, .if / .else / .endif, .ifdef, .ifidni, .repeat, .forc, .endm, .errz |
| Message directives (text, not code) |
.echo Clock: %8d.6:SYS_CLK MHz, .warning ..., .error ... |
| Chip setup |
.ADJUST_IC SYSCLK=IHRC/4, IHRC=16MHz, VDD=3.3V; — units included |
| Macro definitions and calls |
MULT macro x, y / .endm, bare calls like MULT i, 3 |
EQU constants |
System_Clock EQU 8000000 |
| Pin / register configuration |
$ PA.6 Out, High;, $ TM2C SYSCLK, Period; |
| PDK assembly mnemonics |
t0sn, swapc, pushaf, pcadd, idxm, ret, … (PDK13/14/15/16 sets) |
| Registers and flags |
A, SP, PC, CF, ZF, AC, OV |
| SFRs |
PA, PBC, PADIER, TM2C, ADCRGC, LPWMG0DTL, INTEN, … |
| Chip names |
PMS171B, PMS150C, PFS154, … |
| Labels |
next:, and the macro-expanded form loc#i: / goto loc#i; |
| Mini-C operators |
=> compile-time assign, $0/$1 byte index, ## concat, @F / @B local labels |
| Bit access |
PA.6, i.0, arr[1].0 |
| Numbers |
0b_1100_0000, 0xff, 0FFh, 16MHz, 3.3V |
Plus: // and /* */ comments, folding of .if/.endif and macro/.endm blocks,
matching indentation rules, and snippets (fppa0, isr, macro, .if, .forc,
adjustic, $, …).
File association
The language id is padauk. Because Mini-C lives in .c / .h files, the extension
deliberately does not claim those extensions globally — that would break real C
projects. Instead, associate your Padauk tree in settings.json:
"files.associations": {
"/path/to/your/Padauk/**/*.c": "padauk",
"/path/to/your/Padauk/**/*.h": "padauk"
}
Files named .pdkc, .pdkh or .minic are picked up automatically. You can also switch
a single file with the language selector in the status bar (or Cmd+K M).
Maintaining the grammar
The TextMate grammar is generated. Edit the word lists at the top of
tools/gen_grammar.py (SFR names, mnemonics, directives, pin-config words), then:
python3 tools/gen_grammar.py
then re-run ./install.sh and reload the VS Code window. The installed copy under
~/.vscode/extensions/local.padauk-minic-1.0.0 is a build artifact - this repo is the
source of truth.
Install
From the Marketplace: search for Padauk Mini-C in the Extensions view, or
code --install-extension pastaclub.padauk-minic
From source
./install.sh
That regenerates the grammar, packs a .vsix and installs it with the code CLI
(needs only python3, zip and the code command - no npm, no vsce). Then reload the
window: Developer: Reload Window.
To remove it: code --uninstall-extension pastaclub.padauk-minic.
