parrot

parrot

parrot is a simple calculator in go.

my goal is for parrot to be a multi-tool of sorts for command-line maths and computations. I've added a few tools for programmers/designers already, but I'd like these to be modular and plentiful, so I'll be integrating a plug-in system at some point.

working on

• custom math evaluator
• custom parser

current features

• most basic maths
• command history
• live reloading config (courtesy of viper)
• variables
• constant system (poorly designed)
• HTML color converter

planned features

• custom token based math parser to allow units and constants better
• reimplement plugins to be go plugin based, allowing addition of modules without recompilation of the base tool.
• implied multiplication (like "4x" -> "4 * x")
• implement the standard set of math functions
• reimplement constants and variables to be truly dynamic and modular (categories, multiple constant lists)
• more programmer tools
• dynamic config tool
• more config options
• ip calculator: subnet, ip-binary

libraries

• spf13/viper (here to stay)
• sirupsen/logrus (here to stay)
• chzyer/readline (here to stay)
• fatih/color (here to stay)
• go-playground/colors.v1 (will probably be removed, but its a small library used in a tool so eh?)

to deprecate

• Knetic/govaluate (will be removed)
