linker

A golang based cli application that takes a SOURCE path and sets up symlinks to its whole hierarchy from a TARGET path.

Background

I needed a simple tool to quickly setup a linux user configuration by symlinking to the actual configuration files kept in a git repository.

TODOs

Features

• CLI handling
• Read in source files
• Switch on existingFile, existingSymlink, newFile
• Diff files on content
• Create directory structure if missing
• Create symlink
• Backup existing files
• Add dry-run mode (no changes performed to FS)
• Add force mode (no question)
• Add logging to file mode

Verification

• ENV & ARGS (a whole bunch of variations)
• new file
• new file without directories
• existing symlink
• existing file
• dry-run
• force
• Benchmark: Mimic each "handle" test case with a benchmark

Improvements

• Double printouts of short/long version arguments in helper (as well as double handling in the code)
• Integrate debug control into the logger instead of having to have ugly if statements directly in the code
• Wrap up or simplify response handling (2 cases atm)
• What is the correct FileMode to use when making directories instead of 0755?
• Fix so that a single file can be given as source instead of a directory
• Fix so that the prompter accepts an empty string (just newline)
• Extend the logger even further to also have ready generic functionality to log function ENTRY/EXIT
• Extract prompter to interface/package to enable mocking for test purpose
• Add sanity check of source to be a path
• Prints a bunch when enabling debug mode in test, should be handled with a testLogger (that later can be used for log verification)
