Gottani - Combine Go source into a single .go file

What is Gottani

Gottani is a tool for combining Go source code into a single .go file.

In competitive programming, libraries are important to code solutions in a short period of time, but almost all judge environment don't have third party libraries. Many participants with Go need to do "Copy & Paste" between their library code and solution code to be submitted. This is really painful task for participants.

Gottani (ごった煮 meaning Ratatouille in Japanese) is a tool for such use cases. At first, it scans all the files in the specified directory and imported packages from there. Then it copies the functions, constants, variables and types reachable from the main function in the specified package and pastes them into a single file renaming them if needed. Finally it writes the combined source code to stdout.

Installation

# go get github.com/ktateish/gottani/cmd/gottani
