you should use something like mocha for your tests, with that you can just say, this function, when given args, foo and bar, should return baz, and it'll handle the rest for you

Cᴏɴᴏʀ O'Bʀɪᴇɴ

do I have to have tests?

Downgoat

not really but it is good to have tests

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I have my own testing program, just not included in the json

Downgoat

12:05 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ you should put the code to execute your tests in the json otherwise Travis and npm won't pickup on it, and won't run your tests

Cᴏɴᴏʀ O'Bʀɪᴇɴ

but I don't know what's required of a test program

Downgoat

a test program should just test your code and error if a test fails

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh okay

so if it's in js, the scripts.test should be node test.js?

quartata

You make individual unit tests for each component of your code and if one goes wrong you throw big nasty error

Cᴏɴᴏʀ O'Bʀɪᴇɴ

.-.

I'm using assert. does that count?

quartata

12:08 AM

that works

Cᴏɴᴏʀ O'Bʀɪᴇɴ

cool, thanks

btw what is travis

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ yeah

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ A CI tool

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ it's a CI thing that everyone uses

Cᴏɴᴏʀ O'Bʀɪᴇɴ

what's CI?

@CᴏɴᴏʀO'Bʀɪᴇɴ continuous integration

Cᴏɴᴏʀ O'Bʀɪᴇɴ

isn't that a math thing?

also mornamorning

Cᴏɴᴏʀ O'Bʀɪᴇɴ

what does it have to do with coding?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat no sudo.

>_>

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ not in this context

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@CᴏɴᴏʀO'Bʀɪᴇɴ no.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:11 AM

@Quill ._. it's 2000 here

Eᴀsᴛᴇʀʟʏ Iʀᴋ

That is continous curves.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat so.. what does it do?

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ Haha, you could say it is, but I'm never heard that term in a mathematical context.

Downgoat

@EᴀsᴛᴇʀʟʏIʀᴋ oh, cool :D it's working \o/

Eᴀsᴛᴇʀʟʏ Iʀᴋ

which iirc only continous curves can be integrated.

@Downgoat :DDDDDd

quartata

12:12 AM

It means that you push every commit no matter what the changes are and let the ci server tell whether or not it works basically

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat yeah, idk why sudo borks it.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@El'endiaStarman ah, I was thinking of contour integration

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ it's over 9000 here

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ it basically runs some stuff whenever you push to github

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ browsenpm.org/package.json

Downgoat

12:12 AM

that stuff can be tests, deployment code (e.g. push to heroku, publish to npm)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

... I'm not using github? I'm just publishing JS to npm

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ you can always run your own CI

but why aren't you using github?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

because I don't need to

quartata

use github anyways

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'm just writing a module

Eᴀsᴛᴇʀʟʏ Iʀᴋ

12:14 AM

@Quill lol

^^^

^

ugh

I always put my codes in version control (github for ppcg things my personal svn server for everything else). It's a good habit

Cᴏɴᴏʀ O'Bʀɪᴇɴ

what's a version control?

quartata

12:18 AM

Version Control System. Like Git or Subversion.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

oh ok

so, I've done git init. doing git push would do what?

Quill

minbrowser.github.io/min

@CᴏɴᴏʀO'Bʀɪᴇɴ well you need to specify a location and a branch to push to

you can set your github repos as the master location or a custom server, or whatever

quartata

git push would push your changes to the current branch on the default remote

Cᴏɴᴏʀ O'Bʀɪᴇɴ

so would that make a new repo?

Quill

no

quartata

12:23 AM

No. You have to make that online.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

so wait

git is a collection of commands that one is supposed to memorize and get good at... yet you can't make a repo with it

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ you can make a repo using git init

quartata

You could if you had access to the remote. You don't in this case

Downgoat

^

Cᴏɴᴏʀ O'Bʀɪᴇɴ

what's the remote?

Quill

12:24 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ you can make a new local repo like that, just not a remote repo

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ GitHub's servers

Cᴏɴᴏʀ O'Bʀɪᴇɴ

... fuck this nvm

I'm just not coding today >_>

Downgoat

...

quartata

It's really simple, you're overcomplicating it.

Think of git like this

Cᴏɴᴏʀ O'Bʀɪᴇɴ

DON'T GIVE ME THAT SHIT

AHHHHHHHHHHH

sorry, bad day

quartata

12:26 AM

All right.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'm just going to leave bai

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ bai

Quill

12:42 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ git is a strange concept to think about in some sense.... GitHub has a great interactive tutorial you can run through without us overcomplicating it for you... :)

Poke

if he doesn't like git, you could always try to teach him perforce instead x:

quartata

Git is simple when you think of it as a directed grap- wait a second...

Is there any operator in JavaScript that returns a reference?

Quill

passing values by reference? no

feel free to pass variable names as strings and eval though

Downgoat

12:57 AM

@Quill no, I mean like reference. e.g. foo-- returns a value not a reference

should cheddar allow operators to return references

or at least directly mutate a value in the callstack rather than retuning a new one?

Quill

it depends... what usage can you think of that would need referencing

Downgoat

idk i just need to know if I should have that functionality

if you can't think of a need for it, don't add it

@Downgoat not really

Quill

Unless your language has limited operating power, I wouldn't use them. They add a layer of unnecessary complextion to a problem values can solve

@HelkaHomba better not run on goddamn Java

Helka Homba

@Quill Phones run on electricity. Programmers run on java.

Downgoat

@QPaysTaxes ewww, it looks awesome but I really don't want to have to learn Java to work with them

quartata

@QPaysTaxes BTW if you rewrite in C++ I could try and make it a Pepper module which means you could run it in browser with basically zero JS involved (although I'll have to run it through pepper.js for browsers other than chrome)

El'endia Starman

2:32 AM

@QPaysTaxes Is it declared global inside the function as well?

@QPaysTaxes Same way. global var. Declaring it to be global both inside and outside of the function is Python's way of making you be explicit about it.

And also allows two functions to use the same variable, but make it so that only one of them actually uses the global variable.

LegionMammal978

@QPaysTaxes Me neither

El'endia Starman

@QPaysTaxes: Your print_nnl(<string>) can be replaced with print(<string>, flush=True).

while matched_c != 0: can just be while matched_c:, but this isn't real important.

Some of your print functions near the end can similarly be obsoleted or rewritten.

I could look at it more in-depth tomorrow, but right now, it's time for me to go to bed.
