<Daniel-Worrall> I mean, yes, that was my problem in my playground example I tried to reduce it to. Turns out I was trying Foo::Bar::Baz when my object is just Foo::Baz
<FromGitter>
<Blacksmoke16> ah that would do it
<FromGitter>
<Daniel-Worrall> Could it be a more specific error message perhaps
<FromGitter>
<Daniel-Worrall> like undefined contstant
<FromGitter>
<Daniel-Worrall> constant
<FromGitter>
<Blacksmoke16> :shrug: maybe?
<FromGitter>
<eliasjpr> Is there a way to set the timeout limit for all threads
<FromGitter>
<tenebrousedge> you could maybe override Thread#start
<FromGitter>
<tenebrousedge> but that sounds like a bad idea
<FromGitter>
<watzon> Definitely a bad idea

<confact> How do i add headers to response? I get undefined method on Hash, tried with `headers[] =` and `headers.add()`
<FromGitter>
<tenebrousedge> strangely that seems not to be a thing
<FromGitter>
<tenebrousedge> wait
<FromGitter>
<tenebrousedge> no, getter should expose the hash
<FromGitter>
<tenebrousedge> what exactly did you try?
<FromGitter>
<confact> Yea, for some headers it will make sense. But others not.
<FromGitter>
<tenebrousedge> because using macros for static content is not necessary
<FromGitter>
<grkek> I mean what if I want to add more headers
<FromGitter>
<grkek> customize something
<FromGitter>
<grkek> instantly
<FromGitter>
<confact> Most of my headers are not static, they change depending on paths and method
<FromGitter>
<grkek> > See ^ that is what I mean
<FromGitter>
<tenebrousedge> if you can use a constant, use a constant. If you can't use a constant, but you can set the headers at compile-time, use a macro. If you need to set them at runtime, use a normal hash
<FromGitter>
<confact> Normal hash then ;)
<FromGitter>
<grkek> Still
<FromGitter>
<grkek> with a macro it will look better
<FromGitter>
<grkek> and you would get the same code before
<FromGitter>
<grkek> instead of writing something like
<FromGitter>
<tenebrousedge> I'm glad it works that way in your framework
<FromGitter>
<grkek> 😆
<FromGitter>
<grkek> I am not trying to shill my framework
<FromGitter>
<grkek> it just looks good and more readable
<FromGitter>
<grkek> sorry if I offended or anything @tenebrousedge
<FromGitter>
<tenebrousedge> I admit to having rolled my eyes a little bit, but there's nothing wrong with things working that way in your framework. It makes sense and it's convenient
<FromGitter>
<tenebrousedge> I might even go for `headers('a', 'value')`
<FromGitter>
<grkek> I had that but since it would be cumbersome to use with multiple headers I went with the hash merge
<FromGitter>
<tenebrousedge> well, you could do both, no?
<FromGitter>
<grkek> I might be known for shilling but still its just an act of social interaction where I try to share something I found exciting :)
<FromGitter>
<grkek> Yes I could do both I even had it before I removed it
<FromGitter>
<tenebrousedge> you're well within the bounds of politeness as far as self-promotion goes, in my opinion
<FromGitter>
<tenebrousedge> but, I'mma sleep 👋
<FromGitter>
<grkek> Good night mate ❤️

hi
<alex``>
it is not purely related to crystal but I want to convert my dotfiles/bin ruby scripts to crystal. but now I have to compile I cannot store them in bin. do you have a suggestion where to store, and if using shards or just crystal to build them?
<alex``>
I thought to dotfiles/src/<file>.cr, but when compiling they will be stored in bin/ using shards
<alex``>
maybe dotfiles/src/crystal/src/<file>.cr to have the bin in dotfiles/src/crystal/bin and gitignore
<alex``>
is there a way to specify in shards.yml the src/ and bin/ paths?
<repo>
not that i know of
<repo>
but you could also try if crenv works for you
<raz>
i think it's a nice idea but the way it presents itself at the moment is a problem
<raz>
it covers only 10% of the available shards. so if someone new to crystal stumbles on it via google, they may think that's all we have :(
<repo>
why does it cover only 10% of the available shards?
<raz>
i think it's a manual catalog. your shard only appears if you add it with a github PR, or if it's mentioned as a dep in another shard
<repo>
oh wow
<repo>
yeah
<repo>
not one of mine is there
<repo>
well, one is
<repo>
with my old github username

<Blacksmoke16> @confact got some example code that reproduces it?
<FromGitter>
<Blacksmoke16> because i use the same syntax and its fine
<FromGitter>
<Blacksmoke16> fwiw a header value can only be a string so it'll fail if its not
<repo>
raz: i wonder why it didn't scrape the github api to include all current shards
<repo>
*he
<repo>
s/scrape/use/
<raz>
dunno, but agree, manual curation seems like a questionable approach
<repo>
at least as long as there's no builtin helper
<raz>
yup, i mean the only problem with https://crystalshards.xyz seems to be that it only(?) covers github
<repo>
yeah and the search sucks ass
<raz>
would rather extend that to cover other hosts as well, it's not like there are many of them (gitlab and... hm... is there even another one? ;))
<repo>
but tbh i find shards like this in duckduckgo: !gh language:crystal thing i need
<raz>
yeh the search could be better, but as long as the shard name or desc contains a reasonable keyword i usually find what i need
<raz>
i think the important bit is that shards show up w/o the authors having to do anything extra
<repo>
well they don't with rubygems either
<repo>
but otoh bundler uses rubygems
<raz>
yeh but rubygems is centralized. which i don't consider a big problem per se.
<raz>
but decentralized is nicer
<repo>
agreed
<raz>
all things considered crystal looks very good on the pkg mgmt front anyway
<raz>
i mean just look at the trainwrecks that python and js are still stuck with :D
<repo>
i also don't like that shardbox uses categories
<repo>
tags would be much more flexible
<raz>
agree... but both are doomed to never fit right
<raz>
ppl will invent different tags for the same things, disagree on which category something belongs, etc.

<confact> How can I send a http request body to a Proccess? I am doing this now: `Process.run(command, shell: true, input: @context.request.body, output: @context.response)`
<FromGitter>
<Blacksmoke16> is it not working?
<FromGitter>
<Blacksmoke16> prob should also send error output to the response io
<FromGitter>
<trejkaz> I don't suppose there is a cucumber-like tool for crystal?
<FromGitter>
<tenebrousedge> I don't think so. I'd help write one
<FromGitter>
<trejkaz> I think I could probably do it ... the actual goal is to do the ray tracer challenge but it wouldn't be the first time I had to shave a giant yak before even writing one line of code
<FromGitter>
<tenebrousedge> I'm sure you're quite capable. I'm somewhat at loose ends at the moment
<FromGitter>
<trejkaz> oh?
<FromGitter>
<tenebrousedge> I have a side project, but it's got to the point of needing a bunch of JS work, and I'm not thrilled about continuing it. Also, I'd like to contribute a shard to Crystal
<FromGitter>
<trejkaz> hmm web stuff ..
<FromGitter>
<trejkaz> or perhaps not, these days
<FromGitter>
<trejkaz> my main project is stalled for a month or so because I have to wait for collaborators to free up some time
<FromGitter>
<trejkaz> I see someone has *started* a microcuke port...
<FromGitter>
<j8r> I'm seeking a "Crystal web dev" to hire, PM me if interested 😉

<elorest> @j8r I might know a couple people. Remote?
<FromGitter>
<j8r> Yes @elorest , thanks :)
<FromGitter>
<elorest> @faustinoaq would be a great option if he's open.
<FromGitter>
<elorest> He wrote much of the amberframework.com website which is html/js on top of amber/crystal.
<FromGitter>
<j8r> This is the API, a good part is done but there is still work. I can work a bit on it. ⏎ What's remaining is a web frontend
<FromGitter>
<elorest> I've asked this question before but is there any good way to read/write from COM ports in crystal. We're setting the baud rate and other params and then opening it as a File. This sort of works but it's not a blocking call so it just waits forever instead of yielding to other fibers like udp, tcp, socket etc.
<FromGitter>
<elorest> @j8r when you say frontend you mean like react or just html/css?
<FromGitter>
<j8r> @elorest I would prefer a modern frontend for the API
<FromGitter>
<j8r> since it's a new project, I am quite open on the technology
<FromGitter>
<elorest> Ok. I was just thinking if the api's are pretty much written you could almost just find any dev camp kid who is good at react and has maybe touched ruby and they could probably do a decent job.
<FromGitter>
<elorest> @j8r Do you have any suggestions on my Serial/COM port question?
<FromGitter>
<confact> @Blacksmoke16 used a lot of yours input in that repo. thanks for the help.
<FromGitter>
<elorest> How does blocking on crystal gets actually work when it does? Is it essentially check if there's anything new and then `sleep x`?
<FromGitter>

how to keep alnum, digit, etc.?
<alex``>
with tr, I can do `tr -c -d "[:$1:]"`, where `$1` can be a character class, like `alnum`
<FromGitter>
<tenebrousedge> Crystal has `tr`
<FromGitter>
<tenebrousedge> also `gsub` and `delete` and `scan`
<alex``>
tr receives a string literal
<alex``>
so I guess it will not work
<FromGitter>
<Blacksmoke16> hm?
<alex``>
then gsub with a regex?
<FromGitter>
<tenebrousedge> Crystal supports POSIX extensions for regexes
<alex``>
string.gsub(/[^[:alnum]]/, '')
<FromGitter>
<tenebrousedge> e.g. `:alnum:`
<FromGitter>
<tenebrousedge> `[^[:alnum:]]`
<alex``>
yes, but gsub is the best method?
<alex``>
or tr, delete could be used
<FromGitter>
<tenebrousedge> I'd probably do `delete("^a-zA-Z0-9")`
<FromGitter>
<Blacksmoke16> whats the goal?
<FromGitter>
<Blacksmoke16> delete all char/numeric values?
<alex``>
the use case is to create a tiny program to filter non alphanumeric character
<alex``>
to generate a password and pipe to that, for sites that don't allow other than alphanum
<alex``>
make-password alex github.com
<alex``>
make-password alex github.com | alnum | wl-copy
<alex``>
something like that
<FromGitter>
<Blacksmoke16> gotcha
<bougyman>
opr gen --no-chars
<bougyman>
oDWcypusgTOR69
<bougyman>
take a look at opr. it's in ruby but the tool does the needful.
<FromGitter>
<tenebrousedge> but I'd probably do `(0..rand(8,20)).join(&->ALLOWED_CHARS.sample)`
<bougyman>
that's similar to what I do in opr, tenebousedge

if I have src/program1.cr and src/program2.cr, what is the best way to require configuration (like the config file path)?, should the file be in src/ or lib/?
<FromGitter>
<kinxer> @alex`` Are you you talking about compile-time configuration in a non-Crystal file or a Crystal configuration file with things like an OptionParser?
<FromGitter>
<tenebrousedge> for compile-time stuff you could stick something in a /config directory
<alex``>
src/program1 and src/program2 will use XDG_CONFIG_HOME/program/config.yml for config, I want kinda share variables accross the 2 programs
<alex``>
instead of repeating the get config path
<alex``>
I hesitate also between the approach of sub-command
<alex``>
in a single program
<alex``>
not sure the best way to handle that
<alex``>
or if it's simpler to just separate into different program
<alex``>
there is a builtin way to create command-line program with sub commands

<dscottboggs_gitlab> Is there any reason why calling a type doesn't call it's `new` classmethod like Pony's `new create`? ⏎ ⏎ A Constant could be either a type or a proc, in both cases it makes sense to me (although maybe I'm wrong, which is why I'm asking) to have syntax available so all the following examples would be equivalent ⏎ ⏎ ```Complex.new(0, 1) ⏎ Complex.new 0, imag: 1 ⏎ Complex(real: 0, imag: 1)
<FromGitter>
<tenebrousedge> near the bottom, "heredoc"
<FromGitter>
<ezrast_gitlab> @dscottboggs_gitlab Pretty sure `Set{a, b}` is compiler magic; it's roughly syntactic sugar for `Set.new.tap{ |obj| obj << a; obj << b}` (as in, define `<<` and you get `{}` for free)
