hivemind

A prototype of a multi-syntax programming language.

Hivemind has a core language defined by its AST and configurable syntaxes acting like plugins.

The concept of "syntax" for hivemind is similar to

  • a theme for a text editor
  • a skin for a gui app
  • a json/html/xml template for a MVC web app

Syntaxes are defined using code-like examples for core ast nodes and they act in a bidirectional way:

  • they are used to parse source code using that syntax
  • and to render code in that syntax
  • source in each syntax is automatically transltable to another syntax

Tools for the language would also support representations of source grouped by class or methods or as a graph

Syntaxes look like that:

A pythonic syntax:

#if_statement
if <test>:
    <true_branch>
else:
    <else_branch>

#assign
<left> = <right>

#call
<function>(<<args:', '>>)

#attribute
<object>.<label>

#attribute_assign
<object>.<label> = <right>

#binary
<left> <operation> <right>

#list
[<<elements:', '>>]

#method_statement
method <method_name>(<<args:', '>>):
    <<body>>

#class_statement
class <class_name>:
    <<methods:''>>

#module_statement
module <module_name>:
    <<elements>>

A lisp-like syntax

#if_statement
(if <test>
    <true_branch>
    <else_branch>)

#assign
(define <left> <right>)

#method_statement
(method <method_name> (<<args:' '>>)
    <<body>>)

#attribute
<object>.<label>

#attribute_assign
(update <object>.<label> <right>)

#binary
(<operation> <left> <right>)

#call
(! <function> <<args:' '>>)

#list
_(<<elements:' '>>)

#class_statement
(class <class_name>
    <<methods>>)

#module_statement
(module <module_name>
    <<elements>>)

Examples

pythonic example schemelike example

Installation

gem install hivemind

Usage

Run a file

hivemind <filename>

Translate a file into another syntax representation

hivemind render a.hm pythonic a2.hm

Goals

  • Experiment with diffent syntaxes in different contexts
  • Use different sub-language seamlessly across the same codebase
  • A possible solution for the expression problem (just convert between different representations)

Language

The core language is just a simple python/ruby-like language for now.

History

Created for the HackFMI 5

Future development

  • fluid folder/file structure representations
  • editor plugins
  • more syntaxes
