Basically, The pypc can do a preprocess work for any text files, such as mulit-programming language code and plaint text, whatever. of course, the pypc is more valuable for processing the code files. And, the pypc supports boolean, integer, float and string data types, if-else nesting statement and logic caculation for expressions. and supports syntax check as well.
The specification of the files the pypc
The file should have a character or a string for a single line comment. such as "//" for java, "#" for python.So we can say, whatever programming language, if it has a single line comment, it can use the pypc.
Simple example of a preprocess statement
// #define BOOL_VALUE True
// #define INT_VALUE 123
// #ifdef BOOL_VALUE
something here when BOOL_VALUE is TRUE
// #ifdef INT_VALUE == 123
sub if block:
// #<< INT_VALUE
// #else
INT_VALUE is NOT 123
// #endif
// #else
BOOL_VALUE is NOT TRUE
// #endif
After preprocessing, we can get the code below:
something here with BOOL_VALUE is TRUE
sub if block:
// INT_ VALUE == 123
Command Line:
python pypc.py -s srcfile [-d destdir [-e [-i initfile [-m comment ]]]]
-s Source file or directory.
-d Destination file or directory.
-e flag for export, setting -e to export a code version with the parameters you set. Or just comment the useless code, which is easy to debug your code, because the line number of code file will not be changed after preprocessing.
-i Define a initial file, this file will be loaded firstly. The default name of init file is "global.def". You can define some global variables in this file.
-m Define yourself mark for comment. The default is "#".
