asm-brush is small WordPress plugin I wrote and dedicated to the dinosaurs (like me) who still use and want to share assembly language source code. It is a brush designed to work with the SyntaxHighlighter Evolved https://wordpress.org/extend/plugins/syntaxhighlighter/ WordPress plugin (written by Viper), itself based on the SyntaxHighlighter JavaScript package by Alex Gorbatchev. To be able to use this brush, you will need the asm-brush as well as the SyntaxHighlighter Evolved plugins installed. To highlight your assembly code, simply wrap it between [assembly] and [/assembly] or [x86] and [/x86] tags. The brush detects and applies different styles to the following elements: Registers Assembly language user instructions Assembly language system instructions FPU instructions Multimedia instructions MASM specific directives & instructions Numbers (decimal and hexadecimal) IDA (The Interactive Disassembler) labels The styles are easily customizable by editing the CSS file.
