vim-octave

Octave syntax and indentation support for Vim:

• Syntax highlighting is taken from Rik's script
• Identation is ported accordingly using upstream Lua's as a base.

Features

From the syntax file description:

• Highlights entire Octave grammar (endwhile, endfor, etc.), not just Matlab keywords
• Updated to highlight all core Octave functions as of version 4.2.0
• Highlights user functions and anonymous functions [@(...)] from within the .m file being edited
• Use-dependent highlighting of Octave system variables
  • When querying system variables, keyword is highlighted as a constant. For example, var = true, highlights true as a constant.
  • When setting variables or otherwise invoking keyword as a function, keyword is highlighted as a function. For example, var = true (2,4), highlights true as a function.
• Support for multi-line strings with line continuation characters as well as escaped quotes (\" or \') within string.
• Support for multi-line block comments
• Support for highlighting numbers that use hex (0x) or binary (0b) syntax
• Error highlighting for bad number syntax, bad structure variable names, bad block comments, bad line continuations.
• Optional support for highlighting operators (+, -, *, etc.), user variables, or tabs, which can be achieved by uncommenting appropriate tagged lines in the syntax file.

The indentation file provides basic automatic indentation of blocks.
