A cat

A Java implementation of Unix cat. No meows, please. It's a toy program to improve my familiarity with the Java ecosystem.

How to build

NOTE
You'll need to have installed Java SE 17, make and Apache maven.

1. Clone the repo: git clone https://github.com/gyreas/purrcat.git
2. Enter the dir: cd purrcat
3. Build with: make build
4. Run the tests with: make tests (note the 's' in 'tests')
5. Test with: ./app.sh <options & files here>
6. To build a standalone JAR, do: make clean package

TODO

• implement tiny testing library / find a tiny library jar
• add the main branch after test suites is up
• implement file i/o etc
• implement feature's of Unix cat, so that this cat can purr.
• Majestic error/exception handling
• Detect if output file is among input files to avoid blowing the file size.
• reading from stdin and
  • stdin
  • sockets
• bundle as jar, to infinity
• upgrade to maven
• upgrade to gradle
• no more than 4x slower than Unix cat--this purrcat can run too.
