00:35 <renich> Hello! How can I validate an XML file against an XSD?

01:00 <FromGitter> <Blacksmoke16> idt the stdlib has those libxml2 methods bound

01:01 <FromGitter> <Blacksmoke16> sec

01:29 <FromGitter> <Blacksmoke16> renich: Here you go, it's very low level as im just using the bindings directly, referencing https://stackoverflow.com/a/54130484. ⏎ ⏎ https://gist.github.com/Blacksmoke16/98baeb545d9ff5af70fe3966edb2d858

01:30 <FromGitter> <Blacksmoke16> i get no output using the example file and XSD from W3 schools, but setting one of the quantities to `-1` it prints `"Element 'quantity': '-1' is not a valid value of the atomic type 'xs:positiveInteger'.\n"` so seems to work

01:30 <renich> Blacksmoke16: thanks

01:30 <renich> Pretty cool!

01:33 <FromGitter> <Blacksmoke16> could open an issue on GH about it. Maybe that's something they would want in stdlib given we're binding libXML2 anyway? :shrug:

01:33 <renich> That should definitelly go in stdlib. It's super useful.

01:47 <renich> For example, in México, in order to issue "electronic invoices" to our IRS (SAT), we need to validate against xsd.

01:47 <renich> http://omawww.sat.gob.mx/tramitesyservicios/Paginas/anexo_20_version3-3.htm

01:47 <renich> For example, validate against something like this: http://www.sat.gob.mx/sitio_internet/cfd/3/cfdv33.xsd

01:59 <FromGitter> <Blacksmoke16> useful yea, but then comes the question of the API/implementation. I.e. might be a lot and better suited to a shard

02:00 <FromGitter> <Blacksmoke16> deff worth opening an issue for the discussion id say

02:10 <renich> Blacksmoke16: OK, I will.

02:10 <renich> BTW, I am getting a memory violation. https://paste.centos.org/view/62c9b931

02:16 <renich> Blacksmoke16: done. #12131

02:23 <FromGitter> <Blacksmoke16> Yea my example doesn't have any error handling

02:24 <FromGitter> <Blacksmoke16> Probably would need to add some of that in like in the SO post

02:24 <FromGitter> <Blacksmoke16> To see what the actual issue is

14:06 <FromGitter> <paulocoghi> Hello everyone! ⏎ ⏎ Do you know how to inform a functions parameter type is of a specific NamedTuple format? Or it isn't necessary?

14:06 <FromGitter> <paulocoghi> For example:

14:08 <FromGitter> <paulocoghi> ```def update(data : NamedTuple( id: Int32, json : String ) ) ⏎ end``` [https://gitter.im/crystal-lang/crystal?at=62ab3973da83520ac3835d28]

14:09 <FromGitter> <Blacksmoke16> does that not work?

14:09 <FromGitter> <paulocoghi> No

14:09 <FromGitter> <Blacksmoke16> whats the error?

14:10 <FromGitter> <paulocoghi> `syntax error in 'STDIN:62:44': expected ')' or named argument, not json`

14:10 <FromGitter> <Blacksmoke16> and how are you calling the method

14:11 <FromGitter> <Blacksmoke16> ah nvm i see the issue

14:11 <FromGitter> <paulocoghi> Hmmm, maybe this is the reason. The function signature was different and I was updating it. The calling line wasn't updated

14:11 <FromGitter> <Blacksmoke16> it should be `json: String` not `json : String`

14:11 <FromGitter> <paulocoghi> Ah, ok!

14:11 <FromGitter> <paulocoghi> Thanks a lot!

14:11 <FromGitter> <Blacksmoke16> tho i will say named tuples arent really meant to be used to model data as something you pass around

14:11 <FromGitter> <paulocoghi> > ah nvm i see the issue ⏎ ⏎ Exactly. This was the issue

14:11 <FromGitter> <paulocoghi> Thanks a lot again!

14:12 <FromGitter> <Blacksmoke16> consider using a struct like `record Data, id : Int32, json : String` then `update(data : Data)` or something like that

14:12 <FromGitter> <paulocoghi> Interesting! I will do that :)

17:21 <renich> Hey Blacksmoke16, found where to submit errata for the book: https://www.packtpub.com/support/errata

17:27 <FromGitter> <Blacksmoke16> 👍 thanks

20:45 <FromGitter> <Renich:matrix.org> You're welcome.
