05/17/2023, 9:30 PMblank seems like it's working - b

05/17/2023, 9:30 PMperfect - h

05/17/2023, 9:31 PMI just kinda assumed that something like blank would exist internally in core - h

05/17/2023, 9:31 PMthanks for the help - b
bright-gpu-74537
05/17/2023, 9:31 PMno reason for a "no backend" to exist in core - b
bright-gpu-74537
05/17/2023, 9:32 PMit should be an error... not default to some noop - h
happy-agent-4114
05/17/2023, 9:32 PMthe reason is because that's how it worked in my head 🗿 - h

05/17/2023, 9:32 PMI also put like 12 extra files of just interface definitions in all my stuff though so like - b
bright-gpu-74537
05/17/2023, 9:32 PMit doesnt, if you want to compile anything in haxeui, you need to supply certain impls - h
happy-agent-4114
05/17/2023, 9:32 PMI might not be the best metric - b
bright-gpu-74537
05/17/2023, 9:33 PMeverything in core is, essentially, delegated to another (proxy) lib - b
bright-gpu-74537
05/17/2023, 9:33 PMno backend, no haxeui-core - b
bright-gpu-74537
05/17/2023, 9:33 PMits a valid error - h
happy-agent-4114
05/17/2023, 9:34 PMno yeah I get why and it makes sense now - h
happy-agent-4114
05/17/2023, 9:34 PMI just made an assumption based around "if i had written this worse it would be like this" - b
bright-gpu-74537
05/17/2023, 9:35 PMi never, personally, thought about using haxeui-blank in order to work with modules in isolation... makes sense though - p

05/17/2023, 9:36 PMI was going to suggest adding a dummy ComponentImpl.hx file to haxeui-core with
in it, but then you might run into issues with the order in which#error "Backend required"
and the backend are declared in a hxml...haxeui-core - h

05/17/2023, 9:36 PMcould a macro do that? - h
happy-agent-4114
05/17/2023, 9:37 PMiirc there's some way to make macros run on the language server but I have no idea how - p
powerful-morning-89
05/17/2023, 9:37 PMI guess you could add an init macro that adds a onTypeNotFound hook that gives a proper error? - b
bright-gpu-74537
05/17/2023, 9:38 PMi think its a valid error - b
bright-gpu-74537
05/17/2023, 9:38 PMyou didnt include a "ComponentImpl" (for example) in your classpath - p
powerful-morning-89
05/17/2023, 9:39 PMYes, but as we just saw it's not always clear to users how they should fix it. - b
bright-gpu-74537
05/17/2023, 9:40 PMdunno, feels like a special case, adding "#if xyz error are you sure?" doesnt feel sensible to me - b
bright-gpu-74537
05/17/2023, 9:42 PMfourth message - h
happy-agent-4114
05/17/2023, 9:42 PMI thought that was an internal backend - h
happy-agent-4114
05/17/2023, 9:42 PMwhich seems like an oxymoron but - b
bright-gpu-74537
05/17/2023, 9:43 PMi dont know why you would think there would be a "fallback" backend, or what that would do... but... i guess it doesnt matter?
