LuaJIT's DynASM after Syntax for Vim

Syntax file extension for <vm_*.dasc> files in the LuaJIT project to symplifing their reading.

Install

Can be installed via a Vim add-in manager such as Plug, Vundle or Pathogen.

Usage

Once the files are installed the syntax highlighting will be automatically enabled anytime you edit a vm_*.dasc file.

Also global variable g:DascLuaJITFile is set to the part of the filename like:

• "x86"
• "x64"
• "arm"
• "arm64"
• "mips"
• "mips64"
• "ppc"

and can be used for your own needs. If a filename is not matched vm_*.dasc, the variable contains an empty string and the script finishes.

Syntax highlighting

This script contains the following features:

Available LuaJIT constants highlighting

Different macro definitions from <lua.h> <lj_obj.h> <lj_gc.h> are highlighted as constants.

Macroses highlighting

Different macrocommands from the corresponding <vm_*.dasc> file are highlighted as functions. Add this line to yours .vimrc, if you want to disable this behaviour:

let dasc_luajit_no_hl_macro=1

Exclude extensions from highlighting

If you want to avoid definitions from extensions highlighting add to yours .vimrc:

let dasc_luajit_no_extension_luavela=1

or/and

let dasc_luajit_no_extension_tarantool=1

for LuaVela or/and Tarantool) fork correspondingly.

Colorised registers

Host and guest registers are highlighting.

For x86 and x84 also different colors for different register size is used. Size of host and guest registers are matched by the color.

Add this line to yours .vimrc, if you want to disable this feature:

let dasc_luajit_no_hl_registers=1

If you want to enable LuaVela registers coloring (which is different from original LuaJIT and Tarantool) edit this line to yours .vimrc:

let dasc_luajit_luavela_regcol=1
