web: laying the groundwork for future expansion (#7045)
* web: laying the groundwork for future expansion This commit is a hodge-podge of updates and changes to the web. Functional changes: - Makefile: Fixed a bug in the `help` section that prevented the WIDTH from being accurately calculated if `help` was included rather than in-lined. - ESLint: Modified the "unused vars" rule so that variables starting with an underline are not considered by the rule. This allows for elided variables in event handlers. It's not a perfect solution-- a better one would be to use Typescript's function-specialization typing, but there are too many places where we elide or ignore some variables in a function's usage that switching over to specialization would be a huge lift. - locale: It turns out, lit-locale does its own context management. We don't need to have a context at all in this space, and that's one less listener we need to attach t othe DOM. - ModalButton: A small thing, but using `nothing` instead of "html``" allows lit better control over rendering and reduces the number of actual renders of the page. - FormGroup: Provided a means to modify the aria-label, rather than stick with the just the word "Details." Specializing this field will both help users of screen readers in the future, and will allow test suites to find specific form groups now. - RadioButton: provide a more consistent interface to the RadioButton. First, we dispatch the events to the outside world, and we set the value locally so that the current `Form.ts` continues to behave as expected. We also prevent the "button lost value" event from propagating; this presents a unified select-like interface to users of the RadioButtonGroup. The current value semantics are preserved; other clients of the RadioButton do not see a change in behavior. - EventEmitter: If the custom event detail is *not* an object, do not use the object-like semantics for forwarding it; just send it as-is. - Comments: In the course of laying the groundwork for the application wizard, I throw a LOT of comments into the code, describing APIs, interfaces, class and function signatures, to better document the behavior inside and as signposts for future work. * web: permit arrays to be sent in custom events without interpolation. * actually use assignValue or rather serializeFieldRecursive Signed-off-by: Jens Langhammer <jens@goauthentik.io> --------- Signed-off-by: Jens Langhammer <jens@goauthentik.io> Co-authored-by: Jens Langhammer <jens@goauthentik.io>
