This is CodeRay #{CodeRay::VERSION}, a syntax highlighting tool for selected languages.
|
||||
|
||||
usage:
|
||||
coderay [-language] [input] [-format] [output]
|
||||
|
||||
defaults:
|
||||
language detect from input file name or shebang; fall back to plain text
|
||||
input STDIN
|
||||
format detect from output file name or use terminal; fall back to HTML
|
||||
output STDOUT
|
||||
|
||||
common:
|
||||
coderay file.rb # highlight file to terminal
|
||||
coderay file.rb > file.html # highlight file to HTML page
|
||||
coderay file.rb -div > file.html # highlight file to HTML snippet
|
||||
|
||||
configure output:
|
||||
coderay file.py output.json # output tokens as JSON
|
||||
coderay file.py -loc # count lines of code in Python file
|
||||
|
||||
configure input:
|
||||
coderay -python file # specify the input language
|
||||
coderay -ruby # take input from STDIN
|
||||
|
||||
more:
|
||||
coderay stylesheet [style] # print CSS stylesheet
