<naqvis> > I'm not familiar with libmagic, and I'm not entirely clear after some web searching, but does it guess file types from the contents? ⏎ ⏎ @RespiteSage yeah. The same library supports `file` command on *nix systems.

so what's stopping crystal from compiling to shared libraries? assuming we allocate GC so it doesn't conflict with other memory, I suspect we could expose an enter_crystal C function and a Crystal VM.yield function that would stop execution, while executing the Crystal program GC could be ran.
<postmodern>
a lot of C plugin systems use shared libraries, and being able to compile crystal into a shared library would open some doors to us
<straight-shoota>
does seem actively developed, though
<FromGitter>
<rishavs> yeah. :(
<straight-shoota>
what do you need it for?
<FromGitter>
<rishavs> web mails to users for auth verification and normal "contact me" stuff
<straight-shoota>
I'd recommend to use a tried and tested mailsever for this kind of thing, especially receiving inbound mail
<FromGitter>
<rishavs> Should I just use the dev api for GMail for something like this? How does that differs from Saas offerings like Mailchimp, sendgrid etc? (Sorry if question is too naive. Very new to this domain)
<straight-shoota>
mailchimp is for sending newsletters
<straight-shoota>
sendgrid is for mass sending of transactional mails
<straight-shoota>
if you don't have a lot of traffic, you can just use an ordinary mail account like gmail
<FromGitter>
<rishavs> Thanks! ❤️
<FromGitter>
<rishavs> Gmail will also be the simplest thing for me to do. I can add my domain on top of it from the dev console
<straight-shoota>
yes, just start with that
<straight-shoota>
you can always easily plug in something else in case you outgrow it
<straight-shoota>
but that's prob a long way
<FromGitter>
<rishavs> makes sense. Thanks
<yxhuvud>
sendgrid (or something like it, I have certain issues with certain misfeatures of sendgrid) is nice once you feel you want things like bounce handling etc. There is so many ways sending emails can go wrong.
<yxhuvud>
.. and suddenly my stupid bug went away. yay!

straight-shoota: btw, do you know why `def yield(fiber : Fiber) : Nil` in the scheduler exist? I can't find any usages..
<yxhuvud>
I guess it is part of the public api of scheduler, but the scheduler is kinda private for most in any case..

<Dan-Do> 1) I converted the query id from decimal to hexa and updated the above log
<FromGitter>
<Dan-Do> unfortunately the stack trace is always `(running, unable to get backtrace)` (@naqvis showed me yesterday)

<naqvis> what are the main use-cases for `begin ... end`? This doesn't start a new scope
<FromGitter>
<naqvis> so is `begin` just used for exceptional handling mechanism?
<FromGitter>
<Blacksmoke16> for the most part yea. But can also be used to group expressions into one scope. E.g. assign the "return" value of it to a constant
arestifo has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<FromGitter>
<naqvis> > Using ||= begin...end allows you to memoize the result of whatever is run in the begin...end. This is useful for caching the result of resource-intensive computation. ⏎ ⏎ Ruby syntax explanation on SO

<naqvis> i believe same stands for Crystal
<FromGitter>
<Blacksmoke16> yup, use the left value is set, otherwise set/return the right value
<FromGitter>
<naqvis> yeah
<FromGitter>
<Daniel-Worrall> As long as it's a truthy value
<FromGitter>
<Daniel-Worrall> That is, if the return is truthy, it'll memoize it. It can't memoize a falsey value (false/nil)

<HertzDevil> `begin` creates an `Expressions` node in places that don't normally expect them
<FromGitter>
<HertzDevil> mainly arguments to `typeof`
<FromGitter>
<HertzDevil> to me that's actually the predominant usage because of my work on the compiler

<mixflame> i'm trying to use the scalable press api from crystal. here's my code
<FromGitter>
<mixflame> i tried plugging numbers and number strings in doesn't work. maybe broken API yeah but raising the question about crystal, are all formdata numbers sent as strings? not sure what the API wants from me so i figured i'd ask here
<FromGitter>
<mixflame> using crystal-lang 1.0.0
<FromGitter>
<Blacksmoke16> are you able to make the request in postman or something?
<FromGitter>
<mixflame> they don't provide postman lol, i should look for that tho lolz
<FromGitter>
<mixflame> good idea thanks @Blacksmoke16
<FromGitter>
<Blacksmoke16> or curl, or insomnia, or whatever HTTP client you like
<FromGitter>
<Blacksmoke16> get it working there then can port it to crystal
<FromGitter>
<Blacksmoke16> looks like they also support JSON which might be easier
<FromGitter>
<Blacksmoke16> nvm, you're using a file
<FromGitter>
<mixflame> i think their api is being unfriendly, the code im using works and is a port from Imgur uploader, im doing api specific stuff wrong
<FromGitter>
<mixflame> no rush on the feature tho
<FromGitter>
<mixflame> gonna take a break and then i'll post man it, the feature is cool, i won't reveal it yet but i think you'll like it :D
<FromGitter>
<mixflame> if i don't have to apologize for a rude banner ad a fan bought (automagically) and i didn't remove but i had to change the rules of the uploader lol
<FromGitter>
<mixflame> similar uploader for this feature tho
