Commandline interface

uv -l syntax # Listing available syntaxes:
uv -l themes # Listing available themes:
uv lib/uv.rb # Letting to guess the parameters
uv -s yaml -t espresso_libre syntax/ini.syntax Specifying a syntax and a theme

# Output results to `index.html` and copy required files (/eg/ css):
uv -c . syntax/ini.syntax > index.html

uv -h -o latex lib/uv.rb > uv.tex
pdflatex uv.tex

Ruby interface

# List of available syntaxes
puts Uv.syntaxes.join( ", " )

# Listing available themes
puts Uv.themes.join( ", " )

# Parsing a css string. Produce xhtml output, with line numbers using amy theme
result = Uv.parse( text, "xhtml", "css", true, "amy")

# Output copy required files for `xhtml` format to directory `site`
Uv.copy_files "xhtml", "site"

Examples

TODO

less crazy Uv.parse interface -> options hash
replace them gallery example with some nice example code
try using atom cson (https://github.com/atom/language-ruby/blob/master/grammars/ruby.cson)

Updating theme files

Currently only XHTML is "officially" supported by ultraviolet, nevertheless, experimental latex output support already exists and other output formats can be included in the future. This is important because theme conversion is format dependent. For xhmtl, the command is theme2xhtmlrender as shown in the following example.

theme2xhtmlrender Amy.tmTheme

For latex, the command theme2latexrender is used instead.

theme2latexrender Amy.tmTheme
