Development

[Zrrg]

Scoring: File Manager

Assignment

Runs with:

npm run start -- --username=your_username

Or, if arguments are not detected, it might work with:

npm run start -- -- --username=your_username

Commands

ls, list, dir / mkdir / up, back / cd / add, touch, write, w / cat, read / rm , del, remove, delete / rn, rename / cp, copy / mv, move / eol / cpuinfo / home, homedir / userinfo / arch, architecture / hash / compress / decompress / help, ? / .exit, exit, quit, q!

Note

• Would be cool if your terminal supported utf-8, if no there might be question marks in output.
• I had to use currentDirectory(); before each break in switch statement, because if i put it in function after all statments, it shows old folder (async so async). If there are more elegant solution for my case, please let me know.
• compress command deletes original file.

Extra features

• Removing empty directories just with rm by distinguishing between files and directories with isfile.js.
• Logging failed commands in logOutput.js, well originally I had bigger plans for this but don't want to break anything at this point.

Basic Scope

• General
  ✅ - +6 Application accepts username and prints proper message
  ✅ - +10 Application exits if user pressed ctrl+c or sent .exit command and proper message is printed
• Operations fail
  ✅ - +20 Attempts to perform an operation on a non-existent file or work on a non-existent path result in the operation fail
  ✅ - +10 Operation fail doesn't crash application
• Navigation & working directory operations implemented properly
  ✅ - +10 Go upper from current directory
  ✅ - +10 Go to dedicated folder from current directory
  ✅ - +20 List all files and folders in current directory
• Basic operations with files implemented properly
  ✅ - +10 Read file and print it's content in console
  ✅ - +10 Create empty file
  ✅ - +10 Rename file
  ✅ - +10 Copy file
  ✅ - +10 Move file
  ✅ - +10 Delete file
• Operating system info (prints following information in console) implemented properly
  ✅ - +6 Get EOL (default system End-Of-Line)
  ✅ - +10 Get host machine CPUs info (overall amount of CPUS plus model and clock rate (in GHz) for each of them)
  ✅ - +6 Get home directory
  ✅ - +6 Get current system user name (Do not confuse with the username that is set when the application starts)
  ✅ - +6 Get CPU architecture for which Node.js binary has compiled
• Hash calculation implemented properly
  ✅ - +20 Calculate hash for file
• Compress and decompress operations
  ✅ - +20 Compress file (using Brotli algorithm)
  ✅ - +20 Decompress file (using Brotli algorithm)

Advanced Scope

✅ +30 All operations marked as to be implemented using certain streams should be performed using Streams API
✅ +20 No synchronous Node.js API with asynchronous analogues is used (e.g. not used readFileSync instead of readFile)
✅ +20 Codebase is written in ESM modules instead of CommonJS
✅ +20 Codebase is separated (at least 7 modules)

Forfeits

• -95% of total task score Any external tools/libraries are used
• -30% of total task score Commits after deadline (except commits that affect only Readme.md, .gitignore, etc.)
