Rebol syntax highlighting using Google Code Prettify

Rebol grammar for Google Code Prettifer

History

• Started with a hack on lang-lisp.js syntax file

• Now completely re-hacked from bottom up

• All syntax grammar (in lang-rebol.js) built from Rebol scripts

Contributors

• Rebol3 used to build lang-rebol.js (GCP grammar) & HTML files (see build/)

• So do not amend lang-rebol.js or any of the HTML files directly! Important

• See build/ReadMe.txt on how to update and rebuild JS & HTML files

Rules

• General rule... KISS :)

• All datatypes! (defined in build/GCP-datatypes.r) marked as LITERAL (with some exceptions)

• All keywords (Rebol functions - defined in build/GCP-keywords.r) marked as KEYWORD (with some exceptions)

• Rest of Rebol grammar defined in build/template-lang-rebol.js

• Some naive Regex used to cover some syntax rules

• All seems to work well for highlighting Rebol code in web pages (see test-?.html for working examples. See not-working.html for known issues)

• See build/Rules.txt for more detailed rules that were applied

What next?

• Let Rebol community have a look

• Then send test patch back to GCP

• [] And if that all goes well then pester Stackoverflow to update their GCP :)

What to see?

• To test - clone repo and open the test.html files in web browser.
