If the prefix -symbol is directly followed by itself it results -to the symbol itself rather than a preprocessor -directive. - -A file written with gpp contains, text that -can be in any format, gpp does not care how -it is formatted, and lines written in GNU Bash -that are executed and termine which part of -the text should be keept and how it should -be repeated. A line can also be partially -written in GNU Bash to modify it. Each line -that is not in GNU Bash as actually treated -as a echo instruction. - -The preprocessor will try to keep the lines in -the output files in the same position as in -the source files. This will however stop to -work if the processor directives includes -loops or instructions that returns multiple -lines. - - - -@node Invoking -@chapter Invoking - -Syntax for invoking @command{?{GPP}}: -@command{?{GPP} [options...]} - -Short options must not be joined and -the value for a flag must be in a -separate argument from the flag itself. - -For example, @option{--symbol=X} is not allowed, -but @option{--symbol X} is. - -@table @option -@item -s -@itemx --symbol -Set the prefix symbol for preprocessor directives.

You can use a shebang line make to gpp -preprocess the file when executed. - -If @option{--unshebang} is used twice, the second line in the -file will be moved up to the top of the file and the initial -shebang line will be removed. A blank line will be inserted -after the new top line will be added to keep the line numbers -in the output file as near as possible to the line numbers -in the input file.

For example, if you want -to create a preprocess function to make a -ASCII text uppercase you can write: - -@example -@@<uppercase () @{ - lower=qwertyuiopasdfghjklzxcvbnm - upper=QWERTYUIOPASDFGHJKLZXCVBNM - sed y/$lower/$upper/ <<<"$*" -@@>@} -@end example - -Now assume that you have this @command{uppercase} -preprocessor function defined on the top of a -document. Also assume that you are logged in -as the user `twilight' and therefor have the -environment variable @var{USER} set to `twilight'. - -If you in the document, below the definition -of @command{uppercase}, insert the line - -@example -Your are logged in as @@(uppercase $USER). -@end example - -After preprocessing it will say - -@example -Your are logged in as TWILIGHT. -@end example - -@@(...) can be used inline. It executes a -command that can either be defined as a -preprocessor function or be an external program. -Preprocossor directives cannot be used inside -it, everything in it is in GNU Bash. - -@@@{...@} is another inline preprocessor directive, -you can put the name of a preprocessor variable -or environment variable inside it to get the -variable's value. For example, if you are -logged in as `twilight' - -@example -Your are logged in as @@@{USER@}. -@end example - -@noindent -will after preprocessing say - -@example -Your are logged in as twilight. -@end example - -@noindent -@command{gpp} supports all modifications to the -result that Bash does.
