plutoengine:plutocommandparser
PlutoEngine's command parser.
Description
PlutoCommandParser is an attempt to streamline my previous attempts at command parsers. Its main
goal is to provide a streamlined and flexible tokenizer, parser and evaluator for a simple
user-friendly CLI-like language called PlutoCmd.
Goals
- High syntax error tolerance
- Provide implementations for basic Java types, such as primitives and Strings
- Allow extensibility while providing a strong foundation
- Complete user control over localization, no hardcoded Strings
Non-goals
PlutoCmd is not a replacement for standard scripting languages and will most likely never be a Turing-complete language.
Implementation style
Command implementation
Each command has its own final class, abstractions over CommandBase are howered allowed.
Note the usage of ConstantExpression annotation over some interface methods. These
annotations must be respected - methods must be stateless and deterministic.
PlutoCmd language specification
General syntax
[prefix]command [arg1] [arg2] ... [argN]
prefix is an optional identifier String to distinguish PlutoCmd commands from other commands.
command is an alias for a command, handled by one of the command handlers
argX is an argument of the invoked command-function, optionally quoted to preserve whitespace.
