@Dennis Can you pull Charcoal? Thanks

Dennis

@ASCII-only Syncing.

@Dennis Can you pull Bitwise? Thanks

ASCII-only

@Dennis Can you pull Charcoal again? Thanks

Dennis

@MDXF @ASCII-only Syncing.

MD XF

02:10

Thanks again

HyperNeutrino

02:36

@Dennis Can you pull Proton? Thanks :)

MD XF

03:27

@Dennis Oops. Mind pulling Bitwise again? Thanks

Dennis

@HyperNeutrino @MDXF Syncing.

Pavel

@Dennis can you make the permalink fields uneditable? A lot of the time I'll try to select all with <C-a>, forget I have APL keyboard on, insert an ⍺ into the middle of the permalink, and then spend a while trying to figure out why it isn't working.

ATaco

@Pavel I recommend just using command mode :P

Pavel

I still find it odd that the permalink fields are editable

HyperNeutrino

@Dennis Thanks :)

ATaco

@Pavel I like it, incase I want to change the 'Try it Online' text or something.

Dennis

@Pavel I found that useful from time to time, so I'm reluctant to remove it.

ATaco

04:12

@Dennis could you add ARBLE?

(It should also have the PWD problems fixed off the bat this time!)

Pavel

@Dennis Huh? What for?

Dennis

Editing stuff before I copy it. Hadn't happened often, but it has.

@ATaco I'll take a look. Is this related to equa.lua?

Pavel

Yes

It bundles equa and some other libraries together.

#!/usr/bin/env bash

/opt/arble/short.lua .code.tio "$@" < .input.tio

ATaco

short.lua, not arble.lua

Pavel

.oO(y tho)

ATaco

04:19

Name came after the code.

Dennis

@ATaco Should I keep equa.lua for Lua?

ATaco

That's up to you, it's still a usable library.

Pavel

I wonder if anyone's made a permalink featuring equa yet

ATaco

(Yes)

Dennis

@ATaco So you'll keep updating both repos?

Pavel

04:21

@ATaco you should have added the equa repo as a submodule to arble instead of duplicating the source code

ATaco

@Dennis Yes, I plan to.

@Pavel I would have if I knew any more about git than how to push :P

Pavel

@ATaco It's not hard. git submodule add <link-to-equa>

To update it, git submodule update

Dennis

@ATaco What would Hello World look like?

ATaco

"Hello, World!"

Dennis

@ATaco Hm, lua: /opt/arble/short.lua:5: module '.opt.arble.equa' not found suggests otherwise.

lua: /opt/arble/short.lua:5: module '.opt.arble.equa' not found:
        no field package.preload['.opt.arble.equa']
        no file '/usr/share/lua/5.3//opt/arble/equa.lua'
        no file '/usr/share/lua/5.3//opt/arble/equa/init.lua'
        no file '/usr/lib64/lua/5.3//opt/arble/equa.lua'
        no file '/usr/lib64/lua/5.3//opt/arble/equa/init.lua'
        no file './/opt/arble/equa.lua'
        no file './/opt/arble/equa/init.lua'
        no file '/usr/lib64/lua/5.3//opt/arble/equa.so'
        no file '/usr/lib64/lua/5.3/loadall.so'

Pavel

04:38

prependdot.. in the require statement is I think an issue

ATaco

That's fine, surprisingly.

Pavel

But . refers to the working directory.

ATaco

Not in lua.

Hold on, let me try this in Fedora.

Dennis

Question: can I just use the equa.lua from the ARBLE repo?

To be imported from Lua, I mean.

Oh, it's in a subdirectory now? Nevermind.

Pavel

Yes, equa is now a submodule.

I find it intresting that even though the repo is called equa.lua, the created directory is just named equa.

I did not know git did that.

ATaco

04:45

@Dennis Give me a moment, I'm messing with submodules and it's causing me pain.

@Pavel I did this myself, because trying to use a . in a folder name in lua is evil.

Pavel

Yeah, just looked at the commit history and noticed

ATaco

There's an increase in screams of pain now.

Pavel

> Git submodules are the most amazing and annoying thing to ever exist
> --anon

ATaco

I have no idea why, but the submodule isn't cloning into my fedora instance.

Dennis

You need --recursive.

Pavel

04:50

You may have an outdated version of git

Kind-of ninja'd

(--recursive is implicit in recent versions)

ATaco

Alright, after that annoying hurdle, it's working on my fedora instance and my windows instance.

Dennis

Still not working here...

ATaco

Same error? Or a new one?

Dennis

The folder structure has changed, but it's equal otherwise.

ATaco

Wait, why is it searching .//opt/arble/equa.lua, it should be searching /opt/arble/equa.lua

Oh, gosh darnit.

It seems to be trying to use an absolute directory as a local one

Pavel

04:56

My version of Git is 2.10. Fedora's is 1.7, I think?

ATaco

Oh, I think that's because TIO calls these with absolute directories where as I've been testing with local ones.

Pavel

The current git is 2.14.

Dennis

TIO is running 2.13 (Fedora's default), and --recursive is still required.

Pavel

Weird. I cloned arble just now and the submodule was added without --recursive

Dennis

@ATaco Using a relative path doesn't really help.

ua: ../../opt/arble/short.lua:5: module '......opt.arble.equa.equa' not found:
        no field package.preload['......opt.arble.equa.equa']
        no file '/usr/share/lua/5.3///////opt/arble/equa/equa.lua'
        no file '/usr/share/lua/5.3///////opt/arble/equa/equa/init.lua'
        no file '/usr/lib64/lua/5.3///////opt/arble/equa/equa.lua'
        no file '/usr/lib64/lua/5.3///////opt/arble/equa/equa/init.lua'
        no file './//////opt/arble/equa/equa.lua'
        no file './//////opt/arble/equa/equa/init.lua'

@Pavel Did you do something in your .gitconfig?

ATaco

04:59

That's a lot more .s and / then normal.

Pavel

@Dennis Nope

Actually, I installed legit, but I don't think that's relevant

cat .gitconfig
[user]
        email = [email protected]
        name = Pavel Braginskiy
[alias]
        branches = !legit branches
        publish = !legit publish
        unpublish = !legit unpublish
        sync = !legit sync
        switch = !legit switch
        resync = !legit resync
        undo = !legit undo
[filter "lfs"]
        clean = git-lfs clean -- %f
        smudge = git-lfs smudge -- %f
        process = git-lfs filter-process
        required = true

ATaco

I can't recreate the issue, so I'm struggling to fix it, going to need to give me a moment.

Got it!~

Well that didn't entirely fix it.

Yay.

Dennis

What does your LUA_PATH look like?

ATaco

05:14

@Dennis Got it!

LUA_PATH was fine, solution was somewhere completely different to where I was looking.

Commited and pushed.

Dennis

Success!

ATaco

Let it be known that PWD and Lua are sworn enemies.

But this time, this time it works better than ever. This has been a good learning experience.

Pavel

38 mins ago, by Pavel

prependdot.. in the require statement is I think an issue

I was correct for the entirely wrong reason all this time

ATaco

Well, it wasn't an issue.

It just, wasn't the solution.

Pavel

But all you did was remove prependdot and it was fixed

Oh nevermind

I see

ATaco

05:18

package.path is what saved the day.

Dennis

@ATaco tio.run/##SyxKykn9/1/JIzUnJ19HITy/KCdFUen/fwA

ATaco

Thank you, oh kind dennis.

More importantly, thankyou for putting up with PWD shananigans even after I claimed that there would be none.

Pavel

As far as I can tell languages rarely work on the first try

Dennis

@ATaco No problem, bugs happen. Still curious why it worked on your Fedora but not mine though.

ATaco

I was calling it as lua arple/short.lua arple/test.lua, and my CWD was under home.

Probably just a perfect storm.

Dennis

05:28

Right.

ASCII-only

13:39

@Dennis Could you pull Charcoal? Thanks

Dennis

17:41

@ASCII-only Done.

Dennis

20:47

Thanks to the kind people at Wolfram, there now https://tio.run/#mathematica.

Pavel

@Dennis Wooo! Awesome!

ATaco

21:25

Wow, what did wolfram do? I need more info :p

Pavel

22:06

I assume they gave Dennis a key, like with APL.

@Dennis how much space does Mathematica take up? When I tried installing it it was like 20 gigs

Dennis

22:29

@Pavel After deleting a lot of stuff TIO doesn't need, 2.3 GiB.

Pavel

Is that more than Haskell?

Dennis

Slightly, yes.

quartata

22:53

wowie

Did you reach out to them or did they find you?

HyperNeutrino

23:06

@Dennis Could you please pull Proton again? Thanks!

Luis Mendo

@Dennis This Mathematica thing sounds great! Are APL and Mathematica the first non-free languages on TIO? How did Mathematica come to happen? (About APL I know Adám was involved)

HyperNeutrino

wait APL isn't free ._.

ATaco

Wait, this means we can answer C&R challenges in Mathematica now :D

HyperNeutrino

:D

Dennis

@HyperNeutrino I think the language is, but Dyalog's implementation isn't free of charge for all use cases.

@HyperNeutrino Syncing.

HyperNeutrino

23:19

@Dennis Hm okay. And yay thanks :D

Dennis

@quartata They (specifically, Jesús Hernández from Wolfram Research) reached out via email.

HyperNeutrino

:o wolfram knows about TIO :DDDD

Dennis

@ATaco They also helped setting it up. Using it inside the sandbox wasn't easy.

Pavel

I can imagine...

Dennis

@LuisMendo Yes, Dyalog APL and WolframScript/Mathematica are the only ones at this moment.

Luis Mendo

23:23

@Dennis Do you think it would be interesting to add Matlab (even if Octave is already there)? I may be meeting some people from Mathworks soon and if I find the ocasion I could probe them

Dennis

@LuisMendo That would be great! :)

At that point, TIO will probably need a bigger disk. :P

ATaco

I still need to support TIO on patreon, I haven't gotten around to it.

Luis Mendo

@Dennis :-D I'm not at all sure I'll even have the chance to ask, or what their opinion would be, but I'll let you know about any progress

Pavel

23:39

@Dennis RIP feeds btw
