yeah, I think tooling could be better in selenium, but selenium 4 supports video now

George Dietrich

@Blacksmoke16

wait, neither of those looks like cypress

cy.get('#username').click(); is what im familiar with

Sean Gregory

@skinnyjames

oh lol

I was looking at the wrong docs

George Dietrich

@Blacksmoke16

that would do it :P

er .type(username)*

Sean Gregory

@skinnyjames

how would you get the second input if they were like:

<form id="first-form"></form>
<form>
<input id="username-dynamic234231">
<input id="username-dynamic234234">
</form>

I've built abstractions around the query selector api, but it never seems to be the best

cy.get('input[id^="username"]:nth-of-type(2)').type(username)

I'm also a big fan of page object, so I may be biased :)

George Dietrich

@Blacksmoke16

i think in the ideal world of cypress you'd do something like cy.get('[data-test=some-unique-id]') such that you're not relying upon classes/id/order etc

Sean Gregory

@skinnyjames

collections don't usually have unique ids though

George Dietrich

@Blacksmoke16

but, for this example it would be like cy.get('input').eq(2)

er .eq(1), starts at 0

collections of objects from the db or?

Sean Gregory

@skinnyjames

like a list

George Dietrich

@Blacksmoke16

true true, depends on the context. A simple list of strings wouldn't, but a list of something fetched from the db would

<postmodern> here's a weird question i ran into while porting some ruby code to crystal, how does one do an empty named tuple? Trying to port some spec code where a keyword is given an empty options Hash.

George Dietrich

@Blacksmoke16

i think you can just do NamedTuple.new

but ofc, another option is to not use named tuples like that :S

From IRC (bridge bot)

@FromIRC

<postmodern> yeah... what was originally a clever idea of "oh I'll just keyword-splat that Hash of Symbols" now has me reconsidering things as I'm porting this code to crystal

George Dietrich

@Blacksmoke16

using it as a container of named args is its purpose, but when you get into using it to model data it's not longer ideal

named args with default values would prob be easier/more clear

From IRC (bridge bot)

@FromIRC

<postmodern> i really wish you could write type signatures that contained literal values (ex: Int32 | '*')

George Dietrich

@Blacksmoke16

maybe could use an enum for that?

wouldn't be the greatest UX tho needing to do like MyEnum.new(14) tho :/

George Dietrich

@Blacksmoke16

i wonder if that's something you could implement with like ameba

From IRC (bridge bot)

@FromIRC

<postmodern> my edge-case is hexdump code which omitts repeating rows by yielding '*' instead of the incremental row index, so i have to say Int32 | String

George Dietrich

@Blacksmoke16

do you have to yield at all?

probably?

From IRC (bridge bot)

@FromIRC

<postmodern> there are other cases where i could use an enum, like the numeric base (2, 8, 10, or 16), but it's annoying to have to type Base::BINARY instead of just 2

<postmodern> yes because i need to still print the single line with the '*' in it

George Dietrich

@Blacksmoke16

if the arg is typed as the enum, could just do :binary

From IRC (bridge bot)

@FromIRC

<postmodern> similar to hexdump -C output

<postmodern> ah i didn't know symbols could automatically be coerced to enum values?

George Dietrich

@Blacksmoke16

under certain cases yea

From IRC (bridge bot)

@FromIRC

<postmodern> i think i'll make a shard to add NL or EOL constant. shame you can't define a macro with an uppercase name to mimic a constant

George Dietrich

@Blacksmoke16

just make it a constant in the first place?

crystal-lang/crystal#10885

From IRC (bridge bot)

@FromIRC

<postmodern> will the crystal compiler optimize out the constant, or will it fetch the value from memory each time?

George Dietrich

@Blacksmoke16

im not sure, I'm sure LLVM would handle it well tho

From IRC (bridge bot)

@FromIRC

<postmodern> preferance onf whether the NL or EOL constant is top-level or defined in String ?

George Dietrich

@Blacksmoke16

https://godbolt.org/z/5x8vbz173 idk if im doing this right but looks like both methods resolve to the same LLVM IR

imo i'd go top level EOL

er i think that's technically asm?

From IRC (bridge bot)

@FromIRC

<postmodern> i also wish crystal had syntactic sugar for .not_nil!

George Dietrich

@Blacksmoke16

it does, just handle it properly :P

From IRC (bridge bot)

@FromIRC

<postmodern> esp when using multiple not_nil! in a method chain: foo.not_nil!.bar.not_nil!.baz

George Dietrich

@Blacksmoke16

do all of those need to be nilable?

From IRC (bridge bot)

@FromIRC

<postmodern> yes, unfortunately, because it's a drill down API where you can initialize things at a fine-grained level
