oh, shards install --production fails if there isnt a shard.lock

ah crystal-lang/shards#473, the snap plugin needs updated in that case

my as well port it to the v2 plugin system too. Guess I know what ill be doing this weekend :P

From IRC (bridge bot)

@FromIRC

<straight-shoota> It seems there's no v2 plugin for Crystal yet...

From IRC (bridge bot)

@FromIRC

<yxhuvud> Hmm. So why do I get errors? It'd be nice to figure it out :⁠(

@FromIRC

<f1refly> Is work currently going on to support crystal on the m1 mac with homebrew? I introduced one of my colleagues to it about a year ago and he can't use his scripts any more since changing his work computer

From IRC (bridge bot)

@FromIRC

<mps> f1refly: unstall alpine linux in qemu and then you can run crystal in VM

<mps> it works pretty fast

<straight-shoota> On our side aarch64_darwin is completely supported. It's just that an LLVM bug prevented upgrading to LLVM 11.

<straight-shoota> I hear crystal runs very well with Rosetta on M1 chips

<f1refly> neat, i'll tell him

From IRC (bridge bot)

@FromIRC

<yxhuvud> oh, I might have found my issue. I didn't initialize one of the fields I sent into things and apparently it wasn't set to 0 by default. :x

George Dietrich

@Blacksmoke16

@straight-shoota yea planning on taking a stab at porting it to v2 this weekend prob

shouldn't be too bad. In the meantime ill replace --production with --without-development to get the v1 working again at least

is it expected that shards build --production works without a shard.lock?

From IRC (bridge bot)

@FromIRC

<straight-shoota> No, in 0.15.0 --production implies --frozen. Prior to that it was intended to work like this, but it was not enforced.

George Dietrich

@Blacksmoke16

gotcha. and is there a point in doing an install before a build. couldn't we simplify the build process to just like shards build --without-development, iirc the catch is that doesn't run post install hooks or something?

nvm, tested it and it did

@alexherbo2

Is there an alternative to partition but with find?

George Dietrich

@Blacksmoke16

use .index and then idx - 1 idx + 1?

Taupiqueur

@alexherbo2

I think to delete, which get the element and remove from the array

In a directory list, I need to get a yaml file

George Dietrich

@Blacksmoke16

array.index(value).try { |idx| array.delete_at (idx - 1)..(idx +1) }

something like that maybe?

Taupiqueur

@alexherbo2

And other files are snippets

George Dietrich

@Blacksmoke16

not sure i follow

Taupiqueur

@alexherbo2

I have an array of paths, where I need to get the scope.yml, it can be present or not, and evaluate its content, I need to separate it from the snippets files in the file list

George Dietrich

@Blacksmoke16

https://crystal-lang.org/api/master/Array.html#delete(obj):T?-instance-method

returns the value if found, otherwise nil

Taupiqueur

@alexherbo2

Yep, I think delete is close to partition for a single element and with mutation

Kirk Haines

@wyhaines

@alexherbo2 I am still not completely clear on what you are doing, but maybe my little find shard might make it easier? https://github.com/wyhaines/find.cr It lets you traverse a path, acting on what you find, with a really simple API. So you could handle your scope.yml files separately from the rest of the files pretty easily.

@didactic-drunk

file.pos returns 0 after write. Is this a bug?

George Dietrich

@Blacksmoke16

Probably just need to flush

didactic-drunk

@didactic-drunk

Is this by design or leaky abstraction?

George Dietrich

@Blacksmoke16

It flushs at the end, so I'd say by design

I think there's a way to make it always flush

.sync = true maybe

didactic-drunk

@didactic-drunk

It I set sync = false performance takes a nose dive with binary files writing 1-4 bytes at a time.

George Dietrich

@Blacksmoke16

makes sense

didactic-drunk

@didactic-drunk

Is crystal master backwards compatible with 1.0.0? If yes I have this

Error: can't cast Jennifer::QueryBuilder::ModelQuery(T)
to Jennifer::QueryBuilder::ModelQuery(T)

imdrasil/jennifer.cr#373

Rishav Sharan

@rishavs

has anyone integrated their crystal project with Sign in with Google/Apple oauths? I can use some reference here

George Dietrich

@Blacksmoke16

are they any diff than normal OAuth? Is a module in the stdlib you can use

Rishav Sharan

@rishavs

Basic principle is the same, but the clientside sdk are supposed to take care of all the refreshing and the hygiene stuff.

George Dietrich

@Blacksmoke16

if they're spec compliant you could leverage https://crystal-lang.org/api/master/OAuth2.html

 Hi. After a lot of head scratching and mild cussing, I finally managed to compile crystal 1.0.0 on a Raspberry Pi 4 running Raspbian Buster 10. Why? Cuz Crystal is cool. `crystal -v` shows the version minus the compile date. Ok. When I try to build an application I get this error: `Error: can't find file 'prelude'` 'prelude' is located in /usr/share/crystal/src.  How do I tell crystal that? Thanks
