This is mostly to reassure people that we are running the same version
as published on numerus.cat. Or at least, try.
Go 1.18 adds the info from git if the package is build from a git
repository, but this is not the case in OBS, so i instead relay on a
constant for the version number. This constant is “updated” by Debian’s
rules, mostly due to the discussion in [0].

This is mainly to be able to stylize them using CSS; the current style
i set i just a placeholder to check that it works as expected.
Most of these links needs to check for the URI’s prefix, because they
are links to a whole section, but the first link must check for the
exact match, otherwise it would match every other URI, as all of them
start with /company/{uuid}.
The server does not return the markup for the top navigation when usin
HTMx, though, hence i have to change the current class using JavaScript.
I am not sure if the correct value for aria-current is “page” when the
link is not for the actual page the user is currently in, like when is
in the new quote page, but it seems to be the most appropriate value
from the enumeration given in the specifications, except, perhaps, for
the “location” value, but i was unable to find any example of that value
anywhere.
Part of #89.
I use customized built-in components, extended from any HTML elements
(e.g., HTMLDivElement), for product search, multiselect, and tags input
fields. The idea is that people that without JavaScript could still use
the regular, non-customized, inputs.
It turns out, this does not work so well: the CSS assumes that
JavaScript is enabled, and web components supported by the browser. If
one of these fails, then the controls are unusable—the multiselect is
too short, and the tags field accepts invalid characters that the
backend does not validate until it fails with a database error.
We discovered this because Apple does not implement customized built-in
components[0], hence it does not use my JavaScript code and forms,
the expenses forms in particular, are almost useless.
The way to fix this is to replace the regular inputs with autonomous
web components, extended from HTMLElement, using JavaScript, because
it would only do so with JavaScript enabled, and the CSS style would
only apply to these components, not the regular input fields.
However, currently i do not have time to do the proper fix, and have
to use a polyfill for Safari to support customized built-in components.
Shame.

This is for users that belong to more than one company. It is just a
page with links to the home of each company that the user belongs to.
Had to add a second company to the demo data to test it properly, even
though i already have unit tests for multicompany, but, you know….
Using Orca or similar accessibility tools, it was not possible to
understand what these “menus” were intended for because they had only
icons without any alternative text, thus nothing to speak aloud with.
Eventually, we will allow people to upload their own profile images,
but until then we’ll use a “generic” profile icon instead of the closed
icon, that means nothing to users.
We wanted to have the same icon for that menu than for the Account item,
but the one we used until now did not look inside the round button for
the menu, thus we changed the two.
Related to #55.
I tried this already when i started adding filters, but i tried to use
AlpineJS for that, and could not because it would reset the context each
time i submitted the filters, due to HTMx replacing the whole content.
I realized that the only thing i need is some “flag” to show and hide
the form with CSS. I do not even need AlpineJS for that, but i used it
anyway because then i can use the x-cloak thing to hidde the toggle
button for users with JavaScript disabled.
Similarly, the body by default has that “flag” set in the markup, and is
removed when AlpineJS is initialized, thus if JavaScript is disabled the
filters form is shown nevertheless.
I was hit with a couple of bugs: hx-on not properly de-initializing,
with a workaround in 43fffb68 and properly fixed with version 1.9.2;
and elements with naked hx-trigger did not work with hx-boost, as i do
for the tag inline form, fixed in 1.9.1.
The other bug fixed in 1.9.1, play well with other libraries that also
use the window.onpopstate, did not affect me, i believe.
I mainly did it for the new hx-on attribute, to click the update
button on recompute, but it does not seem to work as i think it does.
Anyway, there are some fixed bugs.
From the release announcement[0]:
## New Features
* Support for view transitions, based on the experimental View
Transitions API currently available in Chrome 111+ and coming to
other browsers soon.
* Support for “naked” hx-trigger attributes, where an hx-trigger is
present on an element that does not have an hx-get, etc. defined on
it. Instead, it will trigger the new htmx:triggered event, which
can be responded to via your preferred scripting solution.
* Support for generalized inline event handling via the new hx-on
attribute, which addresses the shortcoming of limited onevent
properties attributes in HTML.
## Improvements & Bug fixes
* A memory leak fix by @croxton

We do not have any design yet for errors and other notifications, so i
followed material design, for now, since we already kind of use their
input fields design.
This time i decided to use AlpineJS because there is not that much HTML
code, and the transitioning is way easier to do in AlpineJS than it
would be with plain JavaScript—not to mention the bugs i would
introduce.
I am not sure if, at the end, all pages that now use
mustRenderAppTemplate will be replaced with mustRenderMainTemplate,
but for now i keep them separate to know which routes are already
“boosted”.
What i really set off on was to refactor the multiselect’s x-data
context to a separate JavaScript file.
I did not see the need at first, thinking that it would not matter
because it was used only in a template and i was not duplicating the
code in my files. However, i then realized that having the context
in the template means the visitor has to download it each and every time
it accesses a form with a multiselect, even if nothing changed, and,
worse, it would download it multiple times if there were many
multiselect controls.
It makes more sense to put all that into a file that the browser would
only download and parse once, if the proper caching is set.
Once i realized that, it was a shame that AlpineJS has no way to do
the same for the HTML structure[0], for the exact same reasons: not
wanting to download many times the same extra <template> and other
markup required to build the control for JavaScript users. And then i
remembered that this is supposed to be custom element’s main selling
point.
At first i tried to create a shadow DOW to replace the <select> with
the same <div> and <ul> that i used with Alpine, but it turns out that
<select> is not one of the allowed elements that can have a shadow root
attached[0].
Therefore, i changed the custom element to extend the <div> for the
<select> and <label> instead—the same element that had the x-init
context—, but i would have to define or include all the styles inside
the shadow DOM, and bring the lang attribute, for it to look like it
did before. Out with the shadow DOM, and modify the <div>’s contents
instead.
At this point the code was so far removed from the declarative way that
AlpineJS promotes that i did not see much value on using it, except for
its reactivity. But, given that this is such a small component, at the
end decided to write it all in plain JavaScript.
It is more code, at least looking only at the code i had to write, but
i love how i only have to add an is="numerus-multiselect" attribute to
HTML for it to work.

I had in the product edit page only because it was easier to test there
while i was developing it, but it is something that should be done for
all select[multiple], of course.
I removed the whole x-cloak thing because i am not sure what would
happen if i do something wrong and Alpine can not initialize the
multiselect; probably show nothing to the user. Now it shows the
native select a fraction of a second, but if i fuck it up at least the
user can still use the app.
This is just to set the correct `lang` attribute on the HTML, so that
text readers can do its job and the `(optional)` suffix of labels gets
the correct ”translation”.
I have been thinking about that, and it does not make that much sense to
have the titles in the Go source anymore: most of them are static text
that i have to remember to set in the controller each time, and when
the time come i have to face a dynamic title i am sure i will manage
with only the template capabilities—worst comes worst, i can always
define a function.
On the other hand, there is no way i can define a template without its
title and i know that everytime that template is used, no matter what
controller rendered it, it will always have that title.
