frinkconv

A wrapper script for interacting with the Frink language, with a focus on converting units

I've tried many CLI unit conversion tools/systems, and so far, have found Frink the best.

However, using it from the CLI can be a bit tedious, so this:

• Handles downloading the JAR/data files
• Wraps frink in rlwrap to provide symbol auto completion (can hit tab to complete unit names) and history support
• Provides 2 interfaces:
  • The default REPL
  • A non-interactive expression mode, which executes anything passed as command line arguments

For the list of supported units, see here

This was converted to modern bash and made configurable from the 'starter script'

Install

Requires: java, rlwrap, wget

Copy the frinkconv script onto your $PATH and make it executable

Could use basher to do that for you:

basher install purarue/frinkconv

Examples

Interactive mode:

$ frinkconv
