Calling all APL wizards: can I call an APL function (defined inside a workspace file) from within the command line?

@J.Sallé from bash / cmd.exe? there's a -script option that lets you pipe APL code into the dyalog process

TIOBot logged in!

$ echo '2 + 3 4' | dyalog -script
5 6

@ngn see, that's why you're the wizards here. Would that work for a tradfn defined inside a workspace? Like so: $ echo 'fnName <args>' | dyalog -script [ws name]

@J.Sallé you could )load the workspace and call the function like you normally would in a session: echo -e ')load ws\nfnName args' | dyalog -script

if it's in a namespace, you need ns.fnName arg

1:27 PM

@ngn Ah! That's exactly what I needed. Thanks a lot!

you're welcome :)

@ngn it seems to be working but I don't see anything being returned (even when I do echo '1 2 + 3 4' | dyalog -script)

I mean, it doesn't error or anything prntscr.com/ke9yb7

Same result on powershell btw

@J.Sallé ah... windows

Yeah I imagine that's the problem

that would be a question for @Adám

Okay, I'll wait and see if he's got some idea how to work it out

1:49 PM

@J.Sallé I don't see -script mentioned among the cmd line options for windows, most likely it's not supported there.

2:01 PM

@ngn yeah but if that was the case wouldn't it throw an error or something? Or at least be mentioned like -s is?

@J.Sallé shrug. It should, but historically Windows culture has always been UI-centred, neglecting the shell. Powershell is relatively new and I guess there hasn't been much demand for Dyalog to behave nicely there.

Yeah, I understand

Socratic Phoenix

2:18 PM

@Adám does the bot always delete message aliases on restart?

@SocraticPhoenix I think so.

Socratic Phoenix

hmmmmmm

how do you restart it

@Adám

@SocraticPhoenix I think the docker container is killed and re-created.

Socratic Phoenix

so the program is just killed D:

@SocraticPhoenix Yeah, but is shouldn't matter. I'm not expecting anything to be saved. I just want what's in the docker container to be loaded.

Socratic Phoenix

2:23 PM

huh

but message aliases?

I think you can configure Docker to call all of the commands you need after starting the program

Socratic Phoenix

except there aren't command line commands for aliases because they're room specific

Not sure though, I know little about docker other than what I see some coworkers doing

Docker only calls command line commands?

@SocraticPhoenix @J.Sallé The new version responds with 03/08/2018 14:30:48'email' and/or 'password' fields are missing from the config.json

Socratic Phoenix

unless it can send a command here :/

does it

but i just tested it >.<

this is confusing

2:25 PM

Looks like it ignores rooms.json

email/password used to be in rooms.json not in config.json. What's the new format?

Socratic Phoenix

it... did?

No idea, the only thing I did was changing the gradle declaration and the class imports

Socratic Phoenix

i haven't touched this project in months and the test config i had has email/password in config ...

Didn't even see a json file, come to think of it

Socratic Phoenix

mmm the json shouldn't have changed at all

2:29 PM

I'm actually just quoting what our IT manager wrote me. I don't have direct access to the bot. Let me check again.

Socratic Phoenix

oh okay

@J.Sallé Does echo 2+2 | dyalog.exe > dyalog.out & type dyalog.out work for you?

Socratic Phoenix

gist.github.com/SocraticPhoenix/…

this is the test config i've been using

for reference i guess :D

@SocraticPhoenix Yes, and I just checked the original files I sent to IT. You're right.

Socratic Phoenix

ok cool

2:32 PM

@Adám it does in cmd. PShell errors out on the &, but doing it in the CMD is good enough I think

Socratic Phoenix

i just don't understand why it would be only the message aliases

I have {"joins":{"STACK_EXCHANGE":[52405]},"password":"*****************","email":"*****@dyalog.com"}

Socratic Phoenix

do command aliases persist

@SocraticPhoenix Yes.

Socratic Phoenix

w e i r d

2:33 PM

@Adám actually I just noticed it returned 2 instead of 4 ⍨

@J.Sallé Yeah, happens by me too, which is why I asked. For some really odd reason (doens't happen by my colleague who gave me the line) it ignores the first two characters, so just put in two more spaces after echo

Socratic Phoenix

how does docker work

@Adám ah, I see.

Socratic Phoenix

is docker recreating the entire environment from a template?

or does the config persist across restarts

i have no idea what docker does D:

*room data, not config

@Adám

@SocraticPhoenix I think it rebuilds everything, using a predefined rooms.json

Socratic Phoenix

2:39 PM

then the only thing i can think of is that that json doesn't have any message aliases in it?

if the file is replaced any you create won't be saved

TIOBot (0.0.6) logged in!

@DyalogAPL Whoo!

@Adám unfortunately I don't think my script will work out :(.

echo   )load "C:\Users\João Sallé\Desktop\stock_exchange.dws"\napl_stock_farmer 1 1 1 1 | dyalog.exe > dyalog.out & type dyalog.out

doesn't work at all. Tried a bunch of variations of it too :/

Can't you just write

echo   \napl_stock_farmer 1 1 1 1 | dyalog.exe "C:\Users\João Sallé\Desktop\stock_exchange.dws" > dyalog.out & type dyalog.out

?

all the aliases went away?

@Adám same thing, no output and no errors

@SocraticPhoenix It seems to ignore rooms.json

#tio alias apl apl-dyalog

@Adám No alias type called "language"

#tio alias apl apl-dyalog

2:47 PM

@Adám expected more arguments...

Socratic Phoenix

wel that is strange

@SocraticPhoenix I don't remember the syntax

Socratic Phoenix

me neither :D

@DyalogAPL cheeky bot, he likes arguing :)

@SocraticPhoenix Do you remember in which directory rooms.json should be?

Socratic Phoenix

2:48 PM

#tio alias lang apl-dyalog apl

@SocraticPhoenix you do not have permission to edit settings for this room!

Socratic Phoenix

i think

@ngn You're its role model.

Socratic Phoenix

@Adám same as config

@Adám :D

what does the room.json look like

Socratic Phoenix

oooh

that's interesting

Seems to be ignoring the STACK_EXCHANGE part?

Socratic Phoenix

2:52 PM

something like that

#tio alias command ⎕← #TIO apl {0::⎕←⊃⎕DM⋄⎕←%args%}(⎕NS⍬).(⎕SE.UCMD'box on -f=on -t=tree'⊣enableSALT⊣⎕CY'salt')

I believe if you look at the rooms.json again it'll now have this alias under STACK_EXCHANGE

2:53 PM

#tio alias command ]help ]help %args% -url

@Adám Added alias for ]help

@J.Sallé it does

Socratic Phoenix

gist.github.com/SocraticPhoenix/… try that

im guessing that an earlier version of the bot saved things differently

in fact i sort of remember changing it and saying something like "room data will break"

@SocraticPhoenix any moment…

TIOBot (0.0.6) logged in!

2:56 PM

@SocraticPhoenix aaaaah, it seems to be appending the STACK_EXCHANGE piece of the JSON to the original one without the STACK_EXCHANGE

Socratic Phoenix

yes

originally it just stored by room id

but there are three chat platforms that can have duplicate room ids

:D

Yeah it's probably a forgotten piece of code

2:57 PM

Perfect.

@SocraticPhoenix Thank you for your help (and for the bot in general)!

Socratic Phoenix

@J.Sallé basically the room.json @Adám had was saved by an older version of the bot that didn't separate rooms by chat platform (stack_exchange, stack_overflow, meta_stack_exchange). At some point I modified the system to save room data separate for each platform, so it was looking under STACK_EXCHANGE and not finding any data.

@J.Sallé Thank you for updating the login system.

Socratic Phoenix

probably my fault for not explaining properly

and @Adám you're welcome :D

@Adám you're very welcome :D

Socratic Phoenix

3:16 PM

i have to be honest i'm pretty hyped this thing is still being used... most of my projects are just dead XD

@SocraticPhoenix Oh, this bot has been a game changer. My APL lessons were so much better due to the ability of me and the attendees to execute APL right there inside the lesson. We are currently working on immortalising this feeling by transforming the lessons to Jupyter notebooks, so that one can still experiment with APL between lesson paragraphs.

Socratic Phoenix

i don't know what Jupyter is but i'm glad it's been helpful

@SocraticPhoenix Like this but the reader can modify and re-execute the APL code.
