sdz80-mode is an emacs major mode that provides some helpers for programming assembler code for the sdas assembler bundled with sdcc.

sdz80-mode extends asm-mode adding the following features:

• imenu integration allows to quickly jump to any label in the file.

  

• highlight Z80 registers.
• implements an electric colon supporting the sdasm double colon syntax for global labels.

  

• automatically add .globl directive for the symbol at point.

  

• updates the header file (.h.s) with all global labels defined in the source code.

  

• display information about Z80 opcodes. Data taken from http://clrhome.org/table/. It allows to sort, filter and show details about the opcodes.

  

• :: electric colon
• C-c m g: declare global symbol at point
• C-c m h: update header file
• C-c m o: show opcodes. Press ? or h in that buffer to futher details.
