Expression2 rewritten in Haxe

expressionscript's Issues

Null Safe

We should be able to enable --macro nullSafety("base", Strict)
Without any errors

update readme

Expression4 link -> Expressive

Fix indexing operator

For some reason even though we accept a comma token it won't move past there. It will instead stay at the comma and not be able to accept a type token.

Repro

E[1,number]

Preprocessor not taking account for strings

"#"

Will break because the preprocessor just scans for hashtags without considering if they are inside a string.

Try catch statement for parser/transpiler

Finished up the work on the wiremod repo, this will have to wait until the Compiler is in a working state

Do while statement

Recently merged into the E2 compiler.

Handle constants through the preprocessor

E2 handles constants through the tokenizer which is just really weird and unintuitive. (We mirrored that for now and it works fine but it feels gross)

Browser demo/repl

Since this is in Haxe, I could just compile this to javascript and deploy to github pages at https://vurv78.github.io/ExpressionScript.

Then everyone could try it out. Would just be the transpiler for now.. for obvious reasons

No Dynamic

We don't want dynamic typing anywhere (It slows down statically typed targets (C++, Hashlink) by a LOT)

Here's where it's used

• [Compiler] Temporary value for E2Context is of type Dynamic
• [Lua Transpiler] call instruction
• [Lua Transpiler] callInstruction
• [Parser] Arguments passed to callInstruction are Dynamic, as we use reflection

Add #include statement

Add another statement in the parser that accepts #include "path". (Might also need to add a new keyword to tokenizer)
See https://github.com/wiremod/wire/wiki/Expression-2#include-directive for more info on what include is.

( It is basically just #include from languages like C++, except it is not through the preprocessor but it is turned into a function that runs in another scope.. yeah it's weird.. )

If you really want to go above and beyond you can also implement it in the lua transpiler side as just require(string).

Use hashlink

Hashlink is miles ahead of c++ for Haxe. Looks like it takes 1/10th of the time to compile, all into one neat file.

Fix unit tests

Giving cryptic errors that I don't want to bother looking into right now.

Use Monaco for Playground

Would be much nicer
