ronn - convert markdown files to manpages
ronn [format...] file... ronn -m|--man file... ronn -S|--server file... ronn --pipe file ronn < file
Ronn converts textfiles to standard roff-formatted Unix manpages or HTML. ronn-format(7) is based on markdown(7) but includes additional rules and syntax geared toward authoring manuals. In its default mode, ronn converts one or more input files to HTML or roff output files. The --roff, --html, and --fragment options dictate which output files are generated. Multiple format arguments may be specified to generate multiple output files. Output files are named after and written to the same directory as input files. The --server and --man options change the output behavior from file generation to serving dynamically generated HTML manpages or viewing file as with man(1). With no file arguments, ronn acts as simple filter. Ronn source text is read from standard input and roff output is written to standard output. Use the --html, --roff, and/or --fragment options to select the output format.
The ronn command expects input to be valid ronn-format(7) text. Source files are typically named name.section.ronn (e.g., example.1.ronn). The name and section should match the name and section defined in the file´s heading. When building roff or HTML output files, destination filenames are determined by taking the basename of the input file and adding the appropriate file extension (or removing the file extension in the case of roff output). For example, executing ronn example.1.ronn generates example.1 with roff output and example.1.html with HTML output.
These options control whether output is written to file(s), standard output, or directly to a man pager. ○ -m, --man: Don´t generate files, display files as if man(1) were invoked on the roff output file. This simulates default man behavior by piping the roff output through groff(1) and the paging program specified by the MANPAGER environment variable. ○ -S, --server: Don´t generate files, start an HTTP server at http://localhost:1207/ and serve dynamically generated HTML for the set of input files. A file named example.2.ronn is served as /example.2.html. There´s also an index page at the root with links to each file. The server respects the --style and document attribute options (--manual, --date, etc.). These same options can be varied at request time by giving them as query parameters: ?manual=FOO&style=dark,toc NOTE: The builtin server is designed to assist in the process of writing and styling manuals. It is in no way recommended as a general purpose web server. ○ --port=port When used with -S/--server, runs the server at the specified port instead of the default port 1207. ○ --pipe: Don´t generate files, write generated output to standard output. This is the default behavior when ronn source text is piped in on standard input and no file arguments are provided. ○ -o=directory, --output-dir=directory: Write generated files to the specified directory instead of the default location. Format options control the files ronn generates, or the output format when the --pipe argument is specified. When no format options are given, both --roff and --html are assumed. -r, --roff Generate roff output. This is the default behavior when no files are given and ronn source text is read from standard input. -5, --html Generate output in HTML format. -f, --fragment Generate output in HTML format but only the document fragment, not the header, title, or footer. Document attributes displayed in the header and footer areas of generated content are specified with these options. (These values may also be set via the ENVIRONMENT.) --manual=manual The name of the manual this man page belongs to; manual is prominently displayed top-center in the header area. --organization=name The name of the group, organization, or individual responsible for publishing the document; name is displayed in the bottom-left footer area. --date=date The document´s published date; date must be formatted YYYY-MM-DD and is displayed in the bottom-center footer area. The file mtime is used when no date is given, or the current time when no file is available. HTML output can be customized through the use of CSS stylesheets: --style=module[,module]... The list of CSS stylesheets to apply to the document. Multiple module arguments may be specified, but must be separated by commas or spaces. When module is a simple word, search for files named module.css in all directories listed in the RONN_STYLE environment variable, and then search internal styles. When module includes a / character, use it as the full path to a stylesheet file. Internal styles are man (included by default), toc, and 80c. See STYLES for descriptions of features added by each module. Miscellaneous options: -w, --warnings Show troff warnings on standard error when performing roff conversion. Warnings are most often the result of a bug in ronn´s HTML to roff conversion logic. -W Disable troff warnings. Warnings are disabled by default. This option can be used to revert the effect of a previous -w argument. -v, --version Show ronn version and exit.
When generating HTML output, ronn hyperlinks manual references (like grep(1), ls(1), markdown(7)) in source text based on reference name to URL mappings defined in an index.txt file. Each line of the index file describes a single reference link, with whitespace separating the reference´s id from its location. Blank lines are allowed; lines beginning with a # character are ignored: # manuals included in this project: whisky(1) whisky.1.ronn tango(5) tango.5.ronn # external manuals grep(1) http://man.cx/grep(1) ls(1) http://man.cx/ls(1) # other URLs for use with markdown reference links src http://github.com/ The location is an absolute or relative URL that usually points at an HTML version of manpage. It´s possible to define references for things that aren´t manpages. All manuals in an individual directory share the references defined in that directory´s index.txt file. Index references may be used explicitly in Markdown reference style links using the syntax: [text][id], where text is the link text and id is a reference name defined in the index.
The --style option selects a list of CSS stylesheets to include in the generated HTML. Styles are applied in the order defined, so each can use the cascade to override previously defined styles. Builtin Stylesheets These styles are included with the distribution: man Basic manpage styles: typography, definition lists, indentation. This is always included regardless of --style argument. It is however possible to replace the default man module with a custom one by placing a man.css file on the RONN_STYLE path. print Basic print stylesheet. The generated <style> tag includes a media=print attribute. toc Enables the Table of Contents navigation. The TOC markup is included in generated HTML by default but hidden with an inline display:none style rule; the toc module turns it on and applies basic TOC styles. dark Light text on a dark background. 80c Changes the display width to mimic the display of a classic 80 character terminal. The default display width causes lines to wrap at a gratuitous 100 characters. Custom Stylesheets Writing custom stylesheets is straight-forward. The following core selectors allow targeting all generated elements: .mp The manual page container element. Present on full documents and document fragments. body#manpage Signifies that the page was fully-generated by Ronn and contains a single manual page (.mp element). .man-decor The three-item heading and footing elements both have this class. .man-head, .man-foot The heading and footing, respectively. .man-title The main <h1> element. Hidden by default unless the manual has no name or section attributes. See the builtin style sources http://github.com/apjanke/ronn-ng/tree/master/lib/ronn/template for examples.
Build roff and HTML output files and view the roff manpage using man(1): $ ronn some-great-program.1.ronn roff: some-great-program.1 html: some-great-program.1.html $ man ./some-great-program.1 Build only the roff manpage for all .ronn files in the current directory: $ ronn --roff *.ronn roff: mv.1 roff: ls.1 roff: cd.1 roff: sh.1 Build only the HTML manpage for a few files and apply the dark and toc stylesheets: $ ronn --html --style=dark,toc mv.1.ronn ls.1.ronn html: mv.1.html html: ls.1.html Generate roff output on standard output and write to file: $ ronn <hello.1.ronn >hello.1 View a ronn file in the same way as man(1) without building a roff file: $ ronn --man hello.1.ronn Serve HTML manpages at http://localhost:1207/ for all *.ronn files under a man/ directory: $ ronn --server man/*.ronn $ open http://localhost:1207/
RONN_MANUAL A default manual name to be displayed in the top-center header area. The --manual option takes precedence over this value. RONN_ORGANIZATION The default manual publishing group, organization, or individual to be displayed in the bottom-left footer area. The --organization option takes precedence over this value. RONN_DATE The default manual date in YYYY-MM-DD format. Displayed in the bottom-center footer area. The --date option takes precedence over this value. RONN_STYLE A PATH-style list of directories to check for stylesheets given to the --style option. Directories are separated by a :; blank entries are ignored. Use . to include the current working directory. MANPAGER The paging program used for man pages. This is typically set to something like ´less -is´. PAGER Used instead of MANPAGER when MANPAGER is not defined.
Ronn is written in Ruby and depends on hpricot and rdiscount, extension libraries that are non-trivial to install on some systems. A more portable version of this program would be welcome.
