Convert source code to syntax-annotated XML

This is a small command-line utility to convert source code to syntax-annotated XML. It is intended to simplify the importing of arbitrary source code artifacts as syntax-highlighted source code text into Adobe InDesign with the help of its Import XML mechanism. Internally, code2xml uses the Node.js Syntax module for highlighting the source code fragments with XML tags named <xxx-root> (root element), <xxx-block[-XXX]> (enclosure element), <xxx-comment>, <xxx-keyword>, <xxx-literal>, <xxx-marker> and <xxx-anchor-N>. Use the Adobe InDesign Map Tags to Styles functionality to map those XML tags to Adobe InDesign styles.

$ npm install -g code2xml

$ code2xml [-h] [-V] [-l <language>] [-o <output-file>] [-f <input-file>]

• -h, --help
  Show usage help.
• -V, --version
  Show program version information.
• -l <language>, --language <language>
  Either "auto" (the default) or one of the languages understood by the Syntax module.
• -i <id>, --id <id>
  Either "" (the default for none) or an identifier to append to the name of the enclosure XML element <xxx-block>.
• -p <prefix>, --prefix <prefix>
  Either "syntax-" (the default) or an identifier to prepend to the name of all XML elements.
• --without-declaration
  Do not emit XML declaration.
• --without-root
  Do not emit root element <xxx-root>.
• --without-file
  Do not emit file element <xxx-file[-XXX]>.
• --without-block
  Do not emit block element <xxx-block>.
• --tab-replace <string>
  replace TAB characters with this string.
• --newline-replace <string>
  replace [CR+]LF characters with this string.
• --regex-anchor-open <regex>
  use this regular expression for anchor opening constructs.
• --regex-anchor-close <regex>
  use this regular expression for anchor closing constructs.
• --regex-marker-open <regex>
  use this regular expression for marker opening constructs.
• --regex-marker-close <regex>
  use this regular expression for marker closing constructs.
• -o <output-file>, --output <output-file>
  Either "-" (the default for stdout) or a path to the XML output file.
• -f <input-file>, --file <input-file>
  Either "-" (the default for stdin) or a path to the source code input file.
