Operation

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.

separator = "-- " text "\n"
shortopt = "-" character
longopt = "--" word
