readme.md

emacs

  • color-theme-sph: a color theme in three versions: dark, light, monochrome
  • sph-scheme-mode: a simpler, faster, standalone emacs mode for editing scheme with regular indentation where indent depth corresponds to nesting depth

sph-scheme-mode

  • syntax highlighting and indentation
  • regular indentation - every nesting step is represented by the same width
  • highlighting of identifiers in definitions (with different colors for variable, procedure and syntax definitions)
  • srfi-62 #;() s-exp comment support
  • strategic syntax highlighting for only a few keywords per default: (if q l debug-log)

versus scheme-mode (scheme.el)

  • scheme-mode includes support for the dsssl-language and many additions for specific implementations
  • lisp/scheme-mode indentation handling takes more than 500 lines, vs ~20 in this implementation using regular indentation
  • ~600 lines to ~200
  • sph-scheme-mode is much faster
  • it is perhaps also a minimal example for learning how to write an emacs mode

installation

move the .el file to a location you seem fitting - the user specific configuration directory like .emacs.d/lisp perhaps, or system-wide like /usr/share/emacs/site-lisp. include it in your emacs configuration, $HOME/.emacs, with a line like (load-library "~/path-to/sph-scheme-mode.elc")"

add the following to your emacs config file

(require (quote sph-scheme-mode))

when the file has been loaded, activate with M-x
