You can use `hscript.Checker` in order to type check and even get completion, using `haxe -xml` output for type information.

Limitations
|
||||
-----------
|
||||
|
||||
Compared to Haxe, limitations are :
|
||||
|
||||
- no type declarations (classes, enums, typedefs) : only expressions
|
||||
- `switch` construct is supported but not pattern matching (no variable capture, we use strict equality to compare `case` values and `switch` value)
|
||||
- only one variable declaration is allowed in `var`
|
||||
- the parser supports optional types for `var` and `function` if `allowTypes` is set, but the interpreter ignores them
|
||||
- you can enable per-expression position tracking by compiling with `-D hscriptPos`
|
||||
- you can parse some type declarations (import, class, typedef, etc.) with parseModule
|
||||
|
||||
Install
|
||||
-------
|
||||
|
||||
In order to install Haxe Script, use `haxelib install hscript` and compile your program with `-lib hscript`.
|
||||
|
||||
There are only three files in hscript :
|
||||
These are the main required files in hscript :
|
||||
|
||||
- `hscript.Expr` : contains enums declarations
|
||||
- `hscript.Parser` : a small parser that turns a string into an expression structure (AST)
|
||||
- `hscript.Interp` : a small interpreter that execute the AST and returns the latest evaluated value
|
||||
|
||||
Some other optional files :
|
||||
|
||||
- `hscript.Async` : converts Expr into asynchronous version
|
||||
- `hscript.Bytes` : Expr serializer/unserializer
|
||||
- `hscript.Checker` : type checking and completion for hscript Expr
|
||||
- `hscript.Macro` : convert Haxe macro into hscript Expr
|
||||
- `hscript.Printer` : convert hscript Expr to String
|
||||
- `hscript.Tools` : utility functions (map/iter)
