These directives are used +to automate the writting of parts of the document. +.PP +The preprocessing directives start with a symbol (or +text string) specified by the developer. By default +this symbol is \fB@\fP (at). +.PP +Any line starting with \fB@<\fP (where \fB@\fP is +the selected symbol for preprocessing directives) +or \fB@>\fP, or is between a line starting with +\fB@<\fP and a line starting with \fB@>\fP, is parsed +as a line, written in +.BR bash (1), +that is executed during preprocessing. A \fB@<\fP +line must have an associated \fB@>\fP line somewhere +after it, all lines between them are parsed as +preprocessing directives. A \fB@>\fP does however +not need an associated \fB@<\fP line somewhere before +it, making \fB@>\fP suitable for single line directives. +.PP +Preprocessing directives can also be inline. For this, +use +.BI @( COMMAND ) +where +.I COMMAND +is the +.BR bash (1) +code to run. Additionally, +.B gpp +supports variable substitution. +.BI @{ VARIABLE } +will be replaces by the value if the variable +(possibility environment variable) +.IR VARIABLE . +.B gpp +supports all modifiers that +.BR bash (1) +supports. For example, if you want the value to be +included but uppercase you can write +.BR @{ \fIVARIABLE\fP ^^} , +or +.BI @{ VARIABLE ,,} +for lowercase. +.PP +Everything that is not preprocessing directives is +threaded as +.BR echo (1):ed +lines. +.SH OPTIONS +.TP +.BR \-s ,\ \-\-symbol \ \fISYMBOL\fP +Set the prefix symbol for preprocessor directives. +Defaults to @ (at). +.TP +.BR \-e ,\ \-\-encoding \ \fIENCODING\fP +Specifies the encoding of the file. +.TP +.BR \-n ,\ \-\-iterations \ \fIN\fP +The the processing \fIN\fP times. Defaults to 1 time. +.TP +.BR \-u ,\ \-\-unshebang +Clear the shebang line, remove it if this flag +is used twice. If used twice, an empty line +will be inserted after the new first line. +.TP +.BR \-i ,\ \-\-input \ \fIFILE\fP +Select file to process. Defaults to /dev/stdin. +.TP +.BR \-o ,\ \-\-output \ \fIFILE\fP +Select output file. Defaults to /dev/stdout. +.TP +.BR \-f ,\ \-\-file \ \fIFILE\fP +Equivalent to \-i \fIFILE\fP \-o \fIFILE\fP. +.TP +.BR \-D ,\ \-\-export \ \fINAME\fP=\fIVALUE\fP +Set the environment variable \fINAME\fP to hold +the value \fIVALUE\fP. +.TP +.BR \-D ,\ \-\-export \ \fINAME\fP +Set the environment variable \fINAME\fP to hold +the value 1. +.TP +.BR \-v ,\ \-\-version +Print program name and version and exit. +.TP +.BR \-c ,\ \-\-copying +Print copyright notice and exit. +.PP +Short options must be joined. The value of a flag must +be in a separate argument from the flag itself. +.SH RATIONALE +Programmers need more automation when we write software +and documentation. An unrestricted preprocessor lets +you automate just about anything. Of course, it can be +used for anything, must just writing software and +documentation. Preprocessing can be used for more than +automation, it can also be used to increase the flexibility +of the work. +.PP +C is one of the few languages that includes a preprocessor, +some times it is not enough; and all languages need +preprocessors. +.SH "SEE ALSO" +.BR bash (1), +.BR jpp (1), +.BR cpp (1) +.PP +Full documentation available locally via: info \(aq(gpp)\(aq +.SH AUTHORS +Principal author, Mattias Andrée.
