Plumb: A Mini Language for Mini Functions
Plumb is a Domain Specific Language for defining small, incidental, throwaway functions. In other words, the 'plumbing' to join the component parts of a program.
Not very useful on its own, Plumb is designed to be embedded into more capable 'host' languages. Implementations are simple to create.
Plumb is actually a special syntax for Lambda Calculus. If you don't know what that is, don't worry ;)
When To Use Plumb?
- When verbosity puts you off using anonymous functions
- When you lack an appropriate argument for map/reduce/filter, and fall back to a loop
- When your codebase doesn't quite fit a library's API
- When you need a little laziness
- When your codebase spans multiple languages
- When it's obvious what you're doing, but the code is tedious
- When some simple argument shuffling is lost in a sea of keywords
When To Avoid Plumb?
- When you're writing important business logic - better to keep the explicit detail
- When you're writing a non-obvious algorithm - don't make it harder to follow
- When your Plumb spans more than a couple of lines - you probably want to refactor into smaller parts
Loading/importing/including Plumb in your language of choice will give you access to the
plumb function. This is the interpreter, which turns Plumb definitions into real functions of your language.
