cli-generate - Generate source and documentation from CLI descriptions
cli-generate [ -c | -h | -m | -w ] FILENAME.cli
Operation cli-generate reads in a CLI (command line interface) description file, parses it into its various sections, and prints out one of a set of output files. In typical usage, that output would be directed to a file and later compiled or included in other sources. The CLI file (named PROGRAM.cli) is divided into two parts, a header (formatted much like a standard mail header) and a series of sections. Headers and sections other than those specified below are ignored. All headers and sections are optional. File Format file = header "\n" *section header = *(header-line "\n") header-line = header-field ":" whitespace value whitespace = *(SPACE / TAB) section = "[" name "]" "\n" lines lines = *( line "\n" ) Headers Description: A one-line description of what the program does. Include: Add C statements to #include the given source file. Must be formatted as either <file> or file Min: The minimum number of allowed non-option arguments. Defaults to 0. Max: The maximum number of allowed non-option arguments. Negative values mean unlimited. Defaults to -1. Show-Pid: Set to non-zero if the resulting program is to show its PID with every output message. Defaults to 0. Usage: A one-line description of the intended usage. Defaults to empty. Section Names [prefix] The text in this section is shown in the command usage before the options description. [options] The list of options this program accepts. See below for their format. [suffix] The text in this section is shown in the command usage after the options description. [description] [return value] [errors] [examples] [environment] [files] [see also] [notes] [caveats] [diagnostics] [bugs] [restrictions] [author] [history] These sections are formatted and copied into the man page in the standard order. Options Format options = *(option / separator) option = option1 "\n" option2 "\n" *(line "\n") option1 = [shortopt] [longopt] type ["=" flag-value] variable ["=" init] option2 = helpstr ["=" default] separator = "-- " text "\n" shortopt = "-" character longopt = "--" word type = "FLAG" / "COUNTER" / "INTEGER" / "UINTEGER" / "STRING" / "STRINGLIST" / "FUNCTION" If not specified, flag-value and init are 0, and default is empty. Formatting Except for [prefix], [options], and [suffix], all of the sections support formatting instructions similar to that of TeXinfo (but greatly simplified). @strong{text} Use "strong" (bold) text. @command{text} Indicate the name of a command. @option{text} Indicate a command-line option. @emph{text} Use "emphatic" (italicized) text. @var{text} Indicate a metasyntactic variable. @env{text} Indicate an environment variable. @file{text} Indicate the name of a file. @code{text} Indicate text that is a literal example of a piece of a program. @samp{text} Indicate text that is a literal example of a sequence of characters. @example @end example The text between these two tags is indented. @verbatim @end verbatim Everything between these two tags is passed as-is (verbatim) to the output. @table @format @end table Mark up a two-column table, or "definition list". @item paragraph Add an item to a table. The @item starts a paragraph that will be the actual list entry. Any subsequent paragraphs will be typeset seperately.
-c Output C source code. -h Output C header file. -m Output a UNIX man page. -w Output HTML (web) markup.
Here is a sample CLI file, containing many of the described elements. Min: 1 Max: 1 Usage: PATH Description: Create a file. Show-Pid: 0 Include: <stdio.h> [prefix] If the given PATH is a directory, it is suffixed with another name. [description] @program generates a new random file from a variety of sources including @command{ls} and @command{ps} output. If the given @option{PATH} is a directory, it is suffixed with another name of my choosing. [options] -v --verbose FLAG=1 opt_verbose -t --type STRING opt_type = "type1" The type of the file to generate. = type1 Possible types for this include @option{type1} and @option{base64}.
