If you turn a python file into an exe using something like py2exe

And the python file has argparse arguments

So like python derp.py --foo "string"

Will it become derp --foo "string" in the exe?

Or is it still python derp.py --foo "string"?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

in what exe

Geobits

@Randal'Thor What's up?

Qwerp-Derp

@EᴀsᴛᴇʀʟʏIʀᴋ What do you mean

@Dennis I don't know if people have already asked you this but will you add JS ES6 to TIO v2 (i.e. babel-node)?

quartata

@Downgoat Can you get the path of the goat silhouette from the SVG of your avatar for me?

Dennis

@Downgoat Is babel-node different from regular node?

Geobits

@Dennis Wait did that get posted to main?

Downgoat

@Dennis babel-node runs code through babel and therefore supports full ES6. Node support is getting better but is still eh :/

@quartata yes, will do rn

Dennis

@Geobits No. In that case, I could have downvoted more than once.

quartata

03:30

@Dennis Babel is a transpiler from ES6 to ES5. It's needed for proper ES6 support

Geobits

Oh ok. My work is done for now then.

Downgoat

@quartata ok: vihan.org/files/upgoat.svg and vihan.org/files/downgoat.svg

chmod -R 777 /usr/bin? Yeah, that's not happening.

Wanna know how I got here? NPM wasn't installing packages in correct dir so without thinking I did what an SO answer proposed and did chown vihan:vihan /usr/bin

another SO answer was stupid and told to do chmod -R 777 /usr/bin and yea

i really goated things up

Dennis

Uh, but that's not even remotely the same thing. chown vihan:vihan /usr/bin would be easy to reverse.

Downgoat

not exactly

you need sudo to un chown it

owait

wat

im not sure how i messed myself up so badly

goat is professional idiot

btw, today i won hackathon :D

Dennis

You don't need sudo if you boot in rescue mode or from a thumb drive.

Downgoat

03:47

i did boot in rescue mode but because i had to mount the disk sudo was not able to load its object files

Dennis

Rescue mode implies logging in as root, and root doesn't require sudo.

Downgoat

oh

root login was disabled over ssh

and DO terminal logged my in as vihan

su command is in /usr/bin and borked beacuse of chmod/own

Dennis

Oh, it was a VM/VPS.

DO allows root logins from terminal though. You just have to reset the root password.

Downgoat

i did

Dennis

Recently went through this because I did something similarly clever.

Downgoat

03:50

but it still didn't work for some reason

i reset root password did all the weird stuff got recovery thing mounted

everything bork at end so i just copy files to new debian VM

Q: Comment-free polyglot with different, nontrivial, behaviour per language

This challenge is inspired by this other challenge, which you may want to read first for some context. However, a competitive answer is likely to look very different, so after reading some posts on Meta I decided it was best posted as a separate question. The goal here is to write a polyglot pro...

It's not as exciting as it sounds, tbh. I was mostly assisting one of the Julia founders with the workshop rather than being the primary presenter.

@trichoplax It seems unclear from the title, but the spec itself is pretty detailed, I thought. My top two concerns about it are 1) it's a "Do X without Y" challenge and 2) it looks very difficult to write an answer that fully complies with spec.

"Would I have fun implementing this?" is always the most important question to ask oneself when creating a language. :)

Qwerp-Derp

Outputs the sum of the first 9 fibonacci numbers

I would have fun, definitely, but I have no idea where to start

It seems like a pretty big project

DLosc

I mean, this sort of case-based recursive definition is something you can do in Haskell, e.g.

Qwerp-Derp

You guys can kinda see the structure of the language here, right?

Alex A.

@Qwerp-Derp Define the syntax, how you want it to look and behave, how to handle weird corner cases. Then look into either writing a parser or using a parser generator.

If you keep the grammar relatively simple, using a lexer/parser generator could be a nice way to get going faster.

I tried to be as general with respect to language features as I could

the "may not read its own source" is a standard restriction on quines; I thought of defining that further but assumed it was well known

What about languages where whitespace is significant? Shouldn't the whitespace count then?

Whether or not a language feature is "intended" for discovering the language and/or version can be debated. Intention isn't a good metric.
