i'll probably just use bash for the question but i was wondering if anyone knows where the tio power-users hang out?

PeterVandivier

it's not immediately obvious how to use it in the tio interface though

PeterVandivier

was going to set up tio examples for a new q and noticed it supports jq as a top-level language? https://tio.run/#jq

@@@ question 1862

samcarter

Hello neighbours! In the TeX community there is currently a question, which after fixing a couple of other issues, now boils down to a path issue. The tex editor finds an old latex binary which came with the ubuntu installation instead of the newer vanilla texlive installation. The user has added the path to the new texlive to their bashrc, so  it works in terminal, but texstudio does not see it. What's the best way to change the path in ubuntu so also applications will see it?

Jack Douglas replying to Anonymous 2002

yes that's right

Hello. If I have a question about Bash, should I post it as a question on the forum here?

Tejas Shetty replying to PeterVandivier

no

PeterVandivier

:cry:

PeterVandivier

ah... nvm... mysql is deprecated as a backend for bareos anyway and it looks like their postgres schema has never included foreign keys

PeterVandivier

i need someone to scream into the void with me

PeterVandivier

anyone else around here use [bareos](https://docs.bareos.org/)? specifically with a mysql backend?

Jack Douglas replying to ps drake

I would think probably not as it's "for Linux, OS/2, MS Windows, OSX, VMS, and many other platforms"

ps drake

`gnuplot` Qs are on-topic here?

Pax

Thanks, Jack! ⭐️

Jack Douglas replying to Pax

done :)

Pax

Hey Jack, should we add tag 'security' in the question I have here?

prabhjot drake replying to Jack Douglas

This wont be low quality Q? If not, then yes, I'll ask here.

Jack Douglas replying to prabhjot drake

please post that as a question :)

prabhjot drake

Is there a way to replace *last* match of `substring` with `replacement`?

prabhjot drake

`${string/substring/replacement}` replaces *first* match of `substring` with `replacement`.

निरंजन replying to PeterVandivier

Why do you think so?

PeterVandivier

hot take: linux is hard

Jack Douglas replying to artaxerxe

yes, just flag it and put a comment in the dedicated chat room saying why your removing

artaxerxe

N.B. The question is mine.

artaxerxe

Can I remove a question on this formu if I see it no more necessary?

PeterVandivier replying to David

:-)

David replying to PeterVandivier

I had a brief fling with Homebrew, and could not get on with it at all. So I blew it away. (I now use MacPorts for the sort of thing I might have wanted Homebrew for, and find it much more stable.) I realize this does not address your question in the slightest, but for some odd reason, I feel better for having shared. :)

PeterVandivier

anyone ever seen brew do a weird duplication thing like this?

David replying to Jack Douglas

Well, I've tried QS now, and will probably stick with it. There are some things that Linux/Ubuntu does better (in my world!) than OSX. Ah well!

David replying to Jack Douglas

A bit sledgehammer for this nut. But thanks! I'm going to try "[script-as-service](https://developer.apple.com/library/archive/documentation/LanguagesUtilities/Conceptual/MacAutomationScriptingGuide/MakeaSystem-WideService.html#//apple_ref/doc/uid/TP40016239-CH46-SW1)" and see if that gets me where I want to go.

David replying to Jack Douglas

Once *is* enough, in this case.

Jack Douglas

I'd risk any dragons to stop endless gif animations :)

Jack Douglas

I have `once` but you can choose `none` I think

David replying to Jack Douglas

There be dragons, but I'll be careful. Thanks!

Jack Douglas replying to David

`image.animation_mode` in about:config!

Jack Douglas replying to David

Have you considered whether something like this would work for you (though it isn't quite the same thing): https://qsapp.com/index.php

David

And on that `ALT+F2` OSX equivalent, I'm [not the only one who wants to know that](https://apple.stackexchange.com/questions/378841). Doesn't look like it exists, sadly.

David replying to Jack Douglas

Huh. I'm using FF, and can't find any setting for "GIF" or "anim\*"...

Jack Douglas replying to David

I think animated gifs is a browser problem, and I have FF configured to play only once!

David

@Jack (You've been really patient with that "DO IT" animated gif! ;) )

David

Right, all: this is a "macos" question, but I'm not sure it's a `ta.nix` question. I know that on Ubuntu I can use `ALT+F2` to run a command. Is there an equivalent on OSX? I don't want Spotlight (`command-spacebar`), as it doesn't find what I want to run. So: is there a key combo that runs a command? (As if it was running from command line on terminal, *but not using terminal*...)??

but yes, it's a bit of a longer term thing :)

Jack Douglas replying to PeterVandivier

I am toying with the idea of creating a variant of TIO which is more like db<>fiddle in it's mechanics

PeterVandivier replying to Jack Douglas

🤔it's entirely possible db<>fiddle is just better fit for purpose at the moment esp. with the `?hide` support. perhaps more complex scripting demos can be a "stretch goal" sort of thing, but not a "right now" thing

Jack Douglas replying to PeterVandivier

at the moment we've only got the 'input', and tbh I don't understand what the different fields mean or why this doesn't produce output: https://tio.run/##XY/BjsIgFEX3fMUNaUIyQo2drZ3duPUHWMgUGhorGGi0rc63z0AbN7Ig4TzuyX1ztH/pmMZ6UMV/pNvxUbpPPktX8YniC633ZRNvJBilITQYywj7Pb6PBxAftAm1PA2q6yEcNtUrgSeiDwOEaDvTaxHNVQU1@FAzzhI9m6nepYg8kdYHBH9H5yCLxUi0J0Db9Sa5l3qyyD@eUPczxIFyCva4hs4NaVL9smQBzE31oOVWFjlZRkuTxxmSmpJ1xyKVe20V7QrZco8s4fENThlOb3DOcM6QNPbiNTYjPvKz3K7afw

PeterVandivier

for Q 712 above, i was thinking about trying to TIO it, but i'm not 100% sure how to handle it gracefully (a la with hidden batches as in db<>fiddle). is there a sensible way to restructure that question with embedded TIO, or is that just too much setup?
