pveyes / naskah Goto Github PK

There's no >= and <= yet

We can name them Operator::Gte and Operator::Lte

Currently we can use any reserved word/token (such as var, if, etc) as identifier in naskah which won't be valid JS. The simplest thing we can do is add underscore before printing the identifier if it's a reserved word in JS

So that:

misal x = 3;
misal var = 2;

jika while benar {
} 

should be compiled to

var x = 3;
var _var = 2;

if (_while == true) {
}

Addition / removal of some newline causes different bug

Case 1: newline required at the end of statement

misal x = 2; // no newline

Output:

salah sintaks

Expected:

var x = 2;

Case 2: Newline between statements

misal x = 2;

misal y = 4;

Output:

var x = 2;

Expected:

var x = 2;
var y = 4;

Knowing strict equality is better for beginner because some errors are due to not knowing how equality work in JS

In JS exponentiation operator is denoted as ** instead of ^

So x ^ 2 should be compiled to x ** 2 in JS

It's shorter and more explicit. Just my 2 cents.

from

misal x = 4;
misal y = x;

to

ada x = 4;
ada y = x;

Currently we didn't track depth level when writing compiled JS code. The solution can be implemented by passing depth as 2nd function argument

fn print_literal(l: Literal, depth: u8) -> String {
  ...
}

Input:

jika x benar {
  menang();
}

Output:

if (x == true) {
menang();
}

Expected:

if (x == true) {
  menang();
}

according to KBBI, javascript const which is constant in english, mean "konstan(t)" in indonesian
also, because javascript "let" is more scoped var, what if we named let to be "variable" instead of using "misal"

Currently typical demo build took ~5 mins. Maybe we can improve it by using

• @actions/cache for target directory
• fetch wasm-pack via cURL instead of cargo`

Reproducible on example page

This should works

jika a benar {
  x = x + 1;
  menang();
}

Currently we have to omit semicolon

jika a benar {
  x = x + 1
  menang()
}

And even the output is wrong (notice the double semicolon on AssignmentExpression)

if (a == true) {
  x = x + 1;;
  menang();
}

We need to list what we're planning to add to the language, not necessarily implement it in parser/printer

Now that now-rust is moved from official package (and have few issues) let's move build & deployment to GitHub action + GitHub pages
