I'm making a programming language

It's really, really in-development. Expect lots to change.

Simple demo:

# This is a comment
print('Hello')

# Set a variable
my_var => 15
print(my_var) # 15

# Change a variable (doesn't break past references)
my_var -> add(my_var 12)
print(my_var) # 27

# Super basic function
my_fn => fn() {
  print('Hello world!')
}
my_fn() # Hello world!

# Function with return value
add_three => fn(x) {
  ^ add(x 3)
}
print(add_three(4)) # 7
print(add_three(mul(2 5))) # 13

Nice big capital letters thing

That is a really nice parser you wrote there.

Great job.

I need to share more of my parsing projects

Oh noeeees

I'm so sorry I wrote it all without using anybody else's code

(except this)

(and this)

__init__

get it right

Neat. Is it functional? Is -> assignment?
It makes me think of Smalltalk in syntax.

fiNe.

Well actually we're trying to decide what's assignment and what's changing.

I think we've agreed on this:

-> change variable Changes the value of a variable without breaking references. Old references will go to this value.
=> assign variable Creates a new variable with the given value. Old references to this variable will still go to the old one.

(It's actually implemented as -> is assign, -= is change, but that makes no sense and I'll be changing it in the code soon.)

Jonathan50 wrote:

Yep - it's all functions (and of course functions are first class).

It's actually not based at all on Smalltak

No, it's not based on Smalltalk (what?) it's just some things are syntactically similar to smalltalk.
Smalltalk also uses an arrow for assignment and a caret for returning values.

Smalltalk, sorry, typo.

Okay

Nize thang

Very cool. Great to see folks starting to experiment with designing their own languages / parsers.

Thanks! Now I feel dedicated (and more motivated) to finishing this again..

Looks like blood, tears, and effort.

That's not a technique from parsing theory that I'm familiar with

Indeed so.

It's really basic parsing. Really basic.

It's a recently-(re)discovered technique that's only just being taught to freshmen now
