This is how you can merge multiple java files into one file. This is very useful for CodinGame participants because CodinGame requires you to upload everything in one file.

File-Merger For InteliJ Idea

This is how you can merge multiple java | kotlin files into one file. This is very useful for CodinGame participants because CodinGame requires you to upload everything in one file.

Installation

1. Download file-merger.sh from this repo into the root of your project.
2. Make sure it is executable (> chmod +x file-merger.sh)
3. Install File Watcher plughin for Intelij Idea
4. Open Settings > Tools > FileWatcher
5. Click '+' , and select custom file
6. Name accordingly (Create separate watchers for each file type)
   1. File type = Any (or Java) | scope = "Project Files" | program = path-to-root-project/file-merger.sh | arguments=$Sourcepath$ java
   2. File type = Any (or Kotlin) | scope = "Project Files" | program = path-to-root-project/file-merger.sh | arguments=$Sourcepath$ kt
7. Apply

Steps 1 & 2 as oneliner

Copy & paste either of the following to download and make executable.

wget https://raw.githubusercontent.com/Savinvadim1312/Java-File-Merger/master/file-merger.sh && chmod +x file-merger.sh

-- or --

curl https://raw.githubusercontent.com/Savinvadim1312/Java-File-Merger/master/file-merger.sh -o file-merger.sh && chmod +x file-merger.sh

Troubleshooting

• Make sure output folder exists (root-project/out)
• Try to run the script manually from root-project dir:

>./file-merger.sh ./src java

Misc

This script will search for all files of specified type under any number of folders from root-project/src/** ignoring files under root-project/src/test/**. It also strips ou package declarations.

FIXED For java classes you have to manually remove the public keyword from them as only one class may have that when declaring multiple classes on the same file.

TODO

• Strip public keyword automatically
