cp_gen

A modular and robust application to create competitive programming templates.

Install

• You must be using Linux since this program uses a syscall (readlink) that is only available on Linux. WSL should work as well.
• Run make to compile the program. It should produce a binary called gen.
• If you want to use gen from anywhere, add the directory cp_gen to your path. Please make sure that gen is in the root directory of this repo since it requires reading/writing library files to templates.

Usage

• Simply enter gen $FILENAME to generate a C++ file. $FILENAME is required.
• The header for generated files is unchangeable unless you modify main.cpp (feel free to).
• Everything after the BEGIN USER CODE line in the generated file is outputted from user.cpp in this repo. You can freely modify this file to your liking. Make sure it includes a main function!
• Everything after the headers and before BEGIN USER CODE is outputted from ./lib/$DS.hpp where you can specify which $DSs you want to be included.

Examples

• gen X.cpp -dsu will include the Disjoint Set Union data structure and generate a file called X.cpp in the current working directory.
• gen ..\above.cpp will generate a file called above.cpp in the directory above the current working directory.
• gen A.cpp -segtree -num will include everything from ./lib/segtree.hpp and ./lib/num.hpp into A.cpp.
• gen my_program.cpp -num will include everything from ./lib/num.hpp in my_program.cpp.

Tests

• To run tests, run make tests.
• If you're interested in adding your own templates and tests, check out ./tests/README.md.
