Elastic Tabstops JavaScript Implementation for Browsers

Usage

var etab = new ElasticTabstops
etab.processLines(document.querySelectorAll('.code-line'))

Examples

Here is the user script for supporting elastic tabstops on github (note currently only tested under tempermonkey). After installing it, you could try some samples in your browser:

• https://github.com/hax/etab/blob/master/src/index.js
• https://github.com/hax/etab/blob/master/src/github-head.js
• https://github.com/hax/etab/blob/master/example/hanging-punc.js

TODO

Core

• try to utilize CSS tab-size
• indent width (normally wide than tab min width for align)
• detect tab size of the source
• extension of alignment:
  • auto aligned[TAB]
  • [SP]right aligned[TAB]
  • left aligned[SP][TAB]
  • [SP]center aligned[SP][TAB]
  • 3.14159 (decimal aligned)[TAB]

Github user script

• test Firefox (with Geasemonkey)
• test IE (with ?)
• add settings button and dialog
• allow change font, tab width and other configurations
• support diff view
• only process the code block that use elastic tabstops
