txt2man(1) txt2man(1) NAME txt2man - convert flat ASCII text to man page format SYNOPSIS txt2man [-hpTX] [-t mytitle] [-P pname] [-r rel] [-s sect] [-v vol] [-I txt] [-B txt] [-d date] [ifile] DESCRIPTION txt2man converts the input text into nroff/troff standard man(7) macros used to format Unix manual pages. Nice pages can be generated specially for commands (section 1 or 8) or for C functions reference (sections 2, 3), with the ability to recognize and format command and function names, flags, types and arguments. txt2man is also able to recognize and format sections, paragraphs, lists (standard, numbered, description, nested), cross references and literal display blocks. If input file ifile is omitted, standard input is used. Result is dis- played on standard output. Here is how text patterns are recognized and processed: Sections These headers are defined by a line in upper case, starting col- umn 1. If there is one or more leading spaces, a sub-section will be generated instead. Optionally, the Section name can be preceded by a blank line. This is useful for a better visualiza- tion of the source text to be used to generate the manpage. Paragraphs They must be separated by a blank line, and left aligned. Al- ternatively two blank spaces can be used to produce the same re- sult. This option will provide a better visualization of the source text to be used to generate the manpage. Tag list The item definition is separated from the item description by at least 2 blank spaces, even before a new line, if definition is too long. Definition will be emphasized by default. Bullet list Bullet list items are defined by the first word being "-" or "*" or "o". Enumerated list The first word must be a number followed by a dot. Literal display blocks This paragraph type is used to display unmodified text, for ex- ample source code. It must be separated by a blank line and be indented by a TAB. It is primarily used to format unmodified source code. It will be printed using fixed font whenever possi- ble (troff). Cross references A cross reference (another man page) is defined by a word fol- lowed by a number in parenthesis. Special sections: NAME The function or command name and short description are set in this section. SYNOPSIS This section receives a special treatment to identify command name, flags and arguments, and propagate corresponding attrib- utes later in the text. If a C like function is recognized (word immediately followed by an open parenthesis), txt2man will print function name in bold font, types in normal font, and variables in italic font. The whole section will be printed using a fixed font family (courier) whenever possible (troff). It is a good practice to embed documentation into source code, by using comments or constant text variables. txt2man allows one to do that, keeping the document source readable, usable even without further for- matting (i.e. for online help) and easy to write. The result is high quality and standard complying document. OPTIONS -h The option -h displays help. -d date Set date in header. Defaults to current date. -P pname Set pname as project name in header. Default to uname -s. -p Probe title, section name and volume. -t mytitle Set mytitle as title of generated man page. -r rel Set rel as project name and release. -s sect Set sect as section in heading, usually a value from 1 to 8. -v vol Set vol as volume name, i.e. "Unix user 's manual". -I txt Italicize txt in output. Can be specified more than once. -B txt Emphasize (bold) txt in output. Can be specified more than once. -T Text result previewing using PAGER, usually more(1). -X X11 result previewing using gxditview(1). ENVIRONMENT PAGER name of paging command, usually more(1), or less(1). If not set falls back to more(1). SOURCE_DATE_EPOCH Unix timestamp that is used for date in header instead of cur- rent date. EXAMPLES Try this command to format this text itself: $ txt2man -h 2>&1 | txt2man -T The following command will generate a manpage level 1 to foo-1.1.0 pro- gram, from foo.txt file, used as source code to previously mentioned manpage: $ txt2man -d "15 May 2016" -t foo -r foo-1.1.0 -s 1 -v "show stars on screen" foo.txt > foo.1 HINTS To obtain an overall good formatting of output document, keep para- graphs indented correctly. If you have unwanted bold sections, search for multiple spaces between words, which are used to identify a tag list (term followed by a description). Choose also carefully the name of command line or function parameters, as they will be emphasized each time they are encountered in the document.
