asciidoctor - converts AsciiDoc source files to HTML, DocBook, and other formats
The asciidoctor(1) command converts the AsciiDoc source file(s) FILE to HTML5, DocBook 5, man(ual) page, and other custom output formats.
If FILE is - then the AsciiDoc source is read from standard input.
- -B, --base-dir=DIR
Base directory containing the document and resources. Defaults to the directory containing the source file or, if the source is read from a stream, the working directory. When combined with the safe mode setting, can be used to chroot the execution of the program.
- -S, --safe-mode=SAFE_MODE
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.
- -a, --attribute=ATTRIBUTE
Define, override, or unset a document attribute. Command-line attributes take precedence over attributes defined in the source file unless either the name or value ends in @.
ATTRIBUTE is normally formatted as a key-value pair, in the form NAME=VALUE. Alternate forms are NAME (where the VALUE defaults to an empty string), NAME! (unsets the NAME attribute), and NAME=VALUE@ (or NAME@=VALUE) (where VALUE does not override the 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.
- -b, --backend=BACKEND
Backend output file format: html5, docbook5, 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.
- -d, --doctype=DOCTYPE
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.
- -D, --destination-dir=DIR
Destination output directory. Defaults to the directory containing the source file or, if the source is read from a stream, the working directory. If specified, the directory is resolved relative to the working directory.
- -E, --template-engine=NAME
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.
- -e, --eruby
Specifies the eRuby implementation to use for executing the custom converter templates written in ERB. Supported values are erb and erubis. Defaults to erb.
- -I, --load-path=DIRECTORY
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.
- -n, --section-numbers
Auto-number section titles. Synonym for --attribute sectnums.
- -o, --out-file=OUT_FILE
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.
- -R, --source-dir=DIR
Source directory. Currently only used if the destination directory is also specified. Used to preserve the directory structure of files converted within this directory in the destination directory. If specified, the directory is resolved relative to the working directory.
- -r, --require=LIBRARY
Require the specified library before executing the processor, using the standard Ruby require. This option may be specified more than once.
- -s, --no-header-footer
Output an embeddable document, which excludes the header, the footer, and everything outside the body of the document. This option is useful for producing documents that can be inserted into an external template.
- -T, --template-dir=DIR
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.
The minimum logging level that triggers a non-zero exit code (failure). If this option is not set (default: FATAL), the program exits with exit code zero even if warnings or errors have been logged.
- -q, --quiet
Silence application log messages and script warnings.
Include backtrace information when reporting errors.
- -v, --verbose
Verbosely print processing information to stderr, including debug-level log messages.
- -w, --warnings
Turn on script warnings (applies to executed code).
- -t, --timings
Print timings report to stderr (time to read, parse, and convert).
Asciidoctor honors the SOURCE_DATE_EPOCH environment variable. If this variable is assigned an integer value, that value is used as the epoch of all input documents and as the local date and time. See https://reproducible-builds.org/specs/source-date-epoch/ for more information about this environment variable.
Failure (syntax or usage error; configuration error; document processing failure; unexpected error).
