Add to asm.yaml?

[mikek88]

I want to add the Raspberry Pi Pico (ARMv6-M) instructions to the asm.yaml syntax highlighting file, but I'd like some clarification about the file structure. Within the statement sections there doesn't appear to be any order. I can just make a line for each category of instruction?...Like putting all of the branch instructions on a separate line? Alphabetizing matters within a line, but not across all lines of the section?

You're probably better off making a separate file for ARM assembly as there is not much overlap between that and NASM x86. It is unfortunate that all kinds of wildly different assembly languages tend to use the same name and file extension.

The order doesn't matter (unless there is overlap between the rules), in asm.yaml they're split just for readability (possibly mirroring some specification document for easy cross-referencing).

A separate YAML file that looks for the same file extension?

A separate syntax file looking for the same extension would be obviously tricky, since it would make it ambiguous for micro which file to use (I think micro would just pick the first one in alphabetical order). But perhaps you might be able to use signature: to remedy that, as documented in https://github.com/zyedidia/micro/blob/master/runtime/help/colors.md#detect-definition

I would invent a better convention to replace the antiquated .s/.S nonsense, like .nasm.s/.armv6-m.s (you can probably come up with something better). If it doesn't get auto-detected perfectly from the file extension you can manually override it with the set filetype command.

I went with a separate file with this detection scheme:

filetype: armv6m-asm

detect:
    filename: "\\.(S|s|asm)$"
    header: "^\\.cpu cortex-m0plus"
