Description

Description:

Returns the preprocessed content of the given file. The preprocessor is C-like, it supports comments using // or /* and */ and PreProcessor_Commands. The preprocessor add also a default debug entrypoint for compiler at the begining of script: #line 1 "aFilename"

The #line keyword can be used in any script that are not preprocess, or with preprocess script with extra macro to protect reserverd sharp character. The format is:
#line <number> "<name>"
followed by new line. <number> could be only positive integer and <name> could be any name. This will be used only if an error occurs in the script. The error will contain the line: File <filename>, line <linenumber>
where <filename> will be the <name> you set and <linenumber> will be <number> + how many lines it is from the #line line. If the error happened on the line right under #line it will add 0 to <number>, if on second line, it will add 1 etc.

It is possible to use more than one #line keywords, but it seems having just one at the top of the script is enough to pinpoint position of the error easily.

The main difference between preprocessFile and preprocessFileLineNumbers is that the latter adds #line keyword to the target file, which allows to log the __LINE__ error happened at and the __FILE__ error happened in.

To custom #line directive with preprocessFileLineNumbers activate, you can use a preprocess macro like this:
#define DEBUG(sharp,name) sharp##line 0 name
and add this at the right place in your code
DEBUG(#,"yourdebugentrypoint");
