Tool to help porting ActionScript 3.0 code to TypeScript.
npm install as3-to-ts> A tool that helps porting as3 codebase to typescript
This fork has major improvements parsing and emitting code. It has also a
"bridge" feature that allows implementing custom node visitors.
This project is a fork of
simonbuchan/as3-to-typescript,
which is a fork of the original
as3-to-typescript
implementation.
Option 1: via npm::
```
npm install -g as3-to-ts
Option 2: building the source:
Make sure you have Node v6+ installed.
- Clone the repository
- Run npm link
You should have as3-to-ts now globaly available in your commandline.
``
as3-to-ts
Options:
- --commonjs: export .ts files using CommonJS's import style.--bridge [name]
- : use custom visitor. implemented under src/bridge/[name]--overwrite
- : force overwrite of previously-converted files.--interactive
- : if you've manually changed a generated .ts file, you'll be
asked if you want to overwrite it or not.
- super calls on constructor need to be moved as the first call after conversion.extends
- having a comment on statement causes infinite loop parsint the .as file.break
- having without a semicolon results in infinite loop parsing the .as file.Error: invalid consume
- having a method without access level will throw .var i = (/comment/true)
(usually this is result of bad copy & paste without renaming the class constructor)
- having inline multiline comment break the parser ()enum
- namespaces can't have TypeScript keywords, such as , class, etc. (not--commonjs
an issue if transpiled using )public var velocityX:Number, velocityY:Number;`)
- multiple property definitions generate invalid syntax (
This tool will not magicly transform your as3 codebase into perfect typescript, the goal is to transform the sources into syntacticly correct typescript, and even this goal is not perfectly respected. It also won't try to provide javascript implementation for flash libraries.
However unlike most attempts that I have seen this tool is based on a true actionscript parser, and so should be able to handle most of as3 constructs and greatly ease the pain of porting a large code base written in as3 to typescript.
