Nit language

Alexis Laferrière

@xymus

The language is declared by a in "Java" before the backtick {

there's C, C++, Java and ObjC

the default is C

Jake Russo

@MadcapJake

very cool!

Alexis Laferrière

@xymus

:wink:

Jake Russo

@MadcapJake

I'm working on language support for Atom Editor and I can have Atom highlight the code inside the backtick { as proper C/C++/Java/ObjC code

Jake Russo

@MadcapJake

I'm basically finished with this: https://atom.io/packages/language-nit

I still need to update the readme, add autoindent/autodedent, and folding rules. But otherwise, it's a working highlighter!

Beyond that, I can integrate into the atom linter and autocomplete plugins. And I have to learn more about building Nit projects but once I do, I could even integrate into the atom-build package!

Writing a text editor proved quite challenging in javascript, I do have some possible paths I could take to get it working but I think I'm more interested in getting solid Atom tooling support.

@xymus

Cool! nice work

Lucas Bajolet

@R4PaSs

Wow, nice !

Jake Russo

@MadcapJake

Thanks! Let me know what you think! Here's the main additions over Sublime-Nit:

outsourced highlighting of C/C++/ObjC/Java code
separate styling for redef, super, and a few others
core types all highlighted differently than defined/other types
method declaration highlighting
first line matching for shebangs

I've looked at some of the examples and it works well, except for one file that crashes Atom every time: perlin_noise.nit

@privat

wow, this is great. What about adding it to http://nitlanguage.org/ide.html ?

Jake Russo

@MadcapJake

Ok I've added it: nitlang/nitlanguage#9

Jake Russo

@MadcapJake

How do you get to that page from the index of the wiki? I can't locate it.

Jake Russo

@MadcapJake

Oh found it, way at the bottom :)

Jake Russo

@MadcapJake

I added another reference to it on the doc page in nitlang/nitlanguage#10

Jake Russo

@MadcapJake

I have this as a list of top-level accessible functions:

sys|main|run|print|inf|nan|pi|srand_from|join_bytes|egid|euid|
gid|uid|args|program_args|program_name|utf8_coder|utf8_decoder|
get_time|nanosleep|getc|getcwd|gets|poll|print_error|printn|
stderr|stdin|stdout|system

is that accurate and did I miss any?

Jake Russo

@MadcapJake

Just trying to highlight builtin/top-level-available methods as support functions (this is common for syntax highlighters). That's why I'm trying to get a list of available functions and types at top-level

Also, for autocomplete support I'll need a big JSON list of these

Alexis Laferrière

@xymus

For highlighting I would stick to the basics: print, print_error, sys, args, program_name

top-level functions are nothing special in Nit

Jake Russo

@MadcapJake

ok good idea, just trying to figure out what's a good set of basics, thanks @xymus !

Jake Russo

@MadcapJake

are there anonymous functions in Nit?

also, can I store a function in a HashMap? If so, how do you signify the type?

Alexis Laferrière

@xymus

There's no anonymous functions in Nit, the closest thing are instances of Task

Jake Russo

@MadcapJake

ok so then I couldn't really store a function in a hashmap then, right?

Alexis Laferrière

@xymus

There are no functions by themselves or as objects, they would need a receiver, so the trick is to store subclasses of Task which implement the desired method.

Jake Russo

@MadcapJake

Any example of this somewhere? stdlib has very little to say about Task

Alexis Laferrière

@xymus

It's quite new, it is used mostly in parallel code to pass bits of code between threads.

I can't find a good example for your use case, the closest is for thread pools which internally keep an Array[Task]at lib/pthreads/examples/threadpool_example.nit

The idea is to subclass Task and implement main. You can store the arguments for the method and its return value as attributes of the class.

Jake Russo

@MadcapJake

But there's no way to dynamically change the body of main is there?

Alexis Laferrière

@xymus

Right, it's static

Jake Russo

@MadcapJake

I was just trying to see if anything from here could be implemented in Nit (as a solution to #1914 ) but without first-class functions, it's not really possible.

@cloutiy

Hello, perhaps it's very obvious and I just missed it,but how does one get user input from the console?

@DanitiKain

I get error when adding repo..

@privat

Hi. Can you be more specific about the issue?

Willyboar

@Willyboar

Hello. Is this project active?

Willyboar

@Willyboar

I guess not.

Hugo Leblanc

@dullin

@Willyboar It is, but being an academic endeavour, asking around X-mas is not bound to have many responses.
The project is alive and well, you can checkout out the latest works by looking at the pull requests https://github.com/nitlang/nit/pulls .

Hi is nitlang still active?

@cloutiy

A shame nit is inactive. For something similar see crystal lang.
