Base directory containing the document and resources. Defaults to the directory containing the source file, or the working directory if the source is read from a stream. When combined with the safe mode setting, can be used to chroot the execution of the program.
Set safe mode level: unsafe, safe, server or secure. Disables potentially dangerous macros in source files, such as include::. If not set, the safe mode level defaults to unsafe when Asciidoctor is invoked using this script.
Set safe mode level to safe. Enables include directives, but prevents access to ancestor paths of source file. Provided for compatibility with the asciidoc command. If not set, the safe mode level defaults to unsafe when Asciidoctor is invoked using this script.
Define, override or delete a document attribute. Command-line attributes take precedence over attributes defined in the source file unless the value ends with @.ATTRIBUTE is normally formatted as a key-value pair, in the form NAME=VALUE. Alternate acceptable forms are NAME (where the VALUE defaults to an empty string), NAME! (unassigns the NAME attribute) and NAME=VALUE@ (where VALUE does not override value of NAME attribute if it’s already defined in the source document). Values containing spaces should be enclosed in quotes.This option may be specified more than once.
Backend output file format: html5, docbook5, docbook45 and manpage are supported out of the box. You can also use the backend alias names html (aliased to html5) or docbook (aliased to docbook5). Other values can be passed, but if Asciidoctor cannot resolve the backend to a converter, it will fail. Defaults to html5.
Document type: article, book, manpage or inline. Sets the root element when using the docbook backend and the style class on the HTML body element when using the html backend. The book document type allows multiple level-0 section titles in a single document. The manpage document type enables parsing of metadata necessary to produce a man page. The inline document type allows the content of a single paragraph to be formatted and returned without wrapping it in a containing element. Defaults to article.
Compact the output by removing blank lines. (No longer in use).
Destination output directory. Defaults to the directory containing the source file, or the working directory if the source is read from a stream. If specified, the directory is resolved relative to the working directory.
Template engine to use for the custom converter templates. The gem with the same name as the engine will be loaded automatically. This name is also used to build the full path to the custom converter templates. If a template engine is not specified, it will be auto-detected based on the file extension of the custom converter templates found.
Specifies the eRuby implementation to use for executing the custom converter templates written in ERB. Supported values are erb and erubis. Defaults to erb.
Add the specified directory to the load path, so that -r can load extensions from outside the default Ruby load path. This option may be specified more than once.
Auto-number section titles. Synonym for --attribute numbered.
Write output to file OUT_FILE. Defaults to the base name of the input file suffixed with backend extension. The file is resolved relative to the working directory. If the input is read from standard input or a named pipe (fifo), then the output file defaults to stdout. If OUT_FILE is -, then the output file is written to standard output.
Require the specified library before executing the processor, using the standard Ruby require. This option may be specified more than once.
Suppress the document header and footer in the output.
A directory containing custom converter templates that override one or more templates from the built-in set. (requires tilt gem)If there is a subfolder that matches the engine name (if specified), that folder is appended to the template directory path. Similarly, if there is a subfolder in the resulting template directory that matches the name of the backend, that folder is appended to the template directory path.This option may be specified more than once. Matching templates found in subsequent directories override ones previously discovered.
Include backtrace information on errors. Not enabled by default.
Verbosely print processing information and configuration file checks to stderr.
Display timings information (time to read, parse and convert).
Print the help message. Show the command usage if TOPIC is not specified (or not recognized). Dump the Asciidoctor man page (in troff/groff format) if TOPIC is manpage.
Print program version number.-v can also be used if no other flags or arguments are present.
Failure (syntax or usage error; configuration error; document processing failure; unexpected error).
