That column was supposed to have a checkbox for batch operations, but
we do not have any operation that would like to perform to many products
or contacts at the same time. For now, at least.
I want the `white-space: pre` to preserve the newline characters that
users may have used, but this prevents line wrapping and long lines are
not confined within the page margins.
`pre-line` preserves the newlines, but collapses spaces and tabs, and
wraps long text, which is more what i want.
I had to change MethodOverrider to check whether the form is encoded as
multipart/form-data or i would not be able to get the method field from
forms with files.
For now i add the file manually, i.e., outside add_expense and
edit_expense PL/pgSQL functions, because it was faster for me, but i
will probably add an attach_to_expense function, or something like that,
to avoid having the whole ON CONFLICT logic inside Golang—this belongs
to the database.
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.
They are almost the same as for the multiselect, except that it “clicks”
the option to “select” it, as this will trigger the replacement of the
<fieldset> with the whole product.
I had a lot of errors when trying to swap an element that has data-hx-on
attribute: it would tell me that it could not swap the bloody thing and
that t.onHandlers is not an iterable. I believe it also happened for
elements that did not have data-hx-on, but i am unsure at this point.
Apparently this is a bug introduced with version 1.9.0 of HTMx that as
of today is not yet fixed[0].
It seems that the problem that they keep the handlers created by
data-hx-on in an object, to be able to remove them afterward, but they
were looping the object with for(… of …) instead of for(… in …).
They will surely fix it in time, but since they will release a new
version, i have decided to change the minified code for now, as there
is no danger of replacing it with the new version—different file names.

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

The product search returns a list of products using its slug as the
“external key”, because i do not want people seeing the id in links,
and the search product list is just a different rendering of the product
index table.
However, now i had two almost identical select queries for product,
one using the product_id and the other its slug, the former intended for
the form to select products using checkboxes—the one non-JavaScript
users see—and the latter for the product search.
Using the slug in both forms i can now simplify the code and have a
single query.
With Oriol agreed that adding or editing invoices, products, and
contacts is not just a “user interruption” but the main flow of the
program, and, as such, it is not correct to use dialogs for these.
More importantly, it was harder to concentrate, specially with the more
involved form of invoices, because of all the “noise” behind the dialog.
I actually find more comfortable to select the product from the list
presented up until now, but this is mostly because i have very few
products and the list is not too long, so the idea is that with
JavaScript we will dynamically add an empty product row to the invoice
and then use the name field to search the product by name.
I have the feeling that i am doing something wrong because i ended up
with a lot of HTMx attribute for what i feel is not that much work,
but for now it will work.
I have added the `Is` field to `InputField` in order to include the `id`
attribute to the HTML element, because the HTMLAttributes are attached
to the `input`, not the `div`, and i felt like this one should also be
a custom element based on div, like all the others.
These is not yet any keyboard control to select the search results.
I am not happy with having the search of products in a different URL
than the index, specially since they use the exact same SQL query and
ProductFilter struct, but i did not know how else ask for a different
representation without resorting to the more complicated MIME types.
I need a way to search products by name in the invoice form, when the
user adds or changes a product. Since this is something that i have to
add too to the product list, i added it now so the function will already
be ready.
I was using the exact same form from edit and new pages of invoice,
which is not too bad considering it won’t change very often, but i now
want to be able to add new empty product lines with the add product
button, and i will need to have a template for that form, which would
mean a third copy.
We have reconsidered the toggle thing and instead moved the selection
into a little menu on top of the input, like the input’s label does à
la Material Design.
I just moved the checkboxes into a new details, that works as a menu,
but i had to add the type="search" to the existing input in the tags
field, or the CSS would style the checkboxes as well.
I do not do anything when the checkbox selection changes because that
already triggers a POST to the server that returns the new HTML with
the checkbox changed, and the JavaScript only has to retrieve that new
structure, exactly as it does in the initial rendering.
Since we want to add a little description to the options, i no longer
can use the same SelectOption in ToggleField, even though i could have
reused the Group element, but that felt wrong.
I realized that using a select for just two, short, options is overkill:
the select and its options use a lot more real state than the two
radios, which can have tooltips (not yet, though).
Since i am going to replace this field with a custom element that has
a toggle-like aspect, i already added the is="numerus-toggle" attribute
and use it for stying the non-JavaScript field.
This is because Oriol thinks that there may be cases where you want to
search invoices and such that have any of the selected labels, not all
of them, so we agreed on adding an option to choose.
The idea is that it will be a toggle, but this requires JavaScript and
this commit adds it as a dropdown as a first non-JavaScript step.
Apparently i was only testing that control with tab, because clicking
on any other non-focusable element (e.g., a table row) it did not add
the new tag and would not dispatch the “numerus-tag-out” custom element,
which is why i have seen it now.
This is equivalent to AlpineJS’s @click.outside, and i was already using
it for the multiselect dropdown. The isConnected check is because i
probably found some cases in the dropdown’s handler, but i can not
remeber now, but since AlpineJS does it too, i guess it is important.
I use the same pattern as HTMx’s “Click to Edit” example[0], except that
my edit form is triggered by submit and by focus out of the tags input.
I could not, however, use the standard focus out event because it would
also trigger when removing a tag with the mouse, as for a moment the
remove button has the focus and the search input dispatches a bubbling
focusout. I had to resort to a custom event for that, but i am not
happy with it.
The autofocus attribute seems to do nothing in this case, so i need to
manually change the focus to the new input with JavaScript. However,
this means that i can not use the same input ID for all the forms
because getElementById would always return the first in document order,
changing the focus to that same element and automatically submit the
form due to focus out. That’s why in this form i append the invoice’s
slug to the input’s ID.
Finally, this is the first time i am using an HTMx-only solution and i
needed a way to return back just the HTML for the <td>, without <title>,
breadcrumbs, or <dialog>. In principle, the template would be the
“layout”, but then i would need to modify everything to check whether
the template file is empty, or something to that effect, so instead i
created a “standalone” template for these cases.

For some reason, i was looking at the value of the focus’ **target**,
which is not my search field at all, but whatever control the focus
changes **to**. It that new control is an input with value, then it
created a new tag with whatever my search field had, which could be the
empty string.
I realized that the event handlers that i was setting when creating the
tags input and the multi-select controls were not removed just because
these elements are no longer in the document, and kept firing again and
again.
I no longer can use an anonymous function, because removeEventListener
would not match it with the one passed to addEventListener. I also have
to bind the handler to `this` in order to keep having access to the
object, and, again, can not do it in the call to addEventListener, or
i would get a different function each time.
I added the check to see if the element is connected inside the
connectedCallback because the documentation warns that this callback
“may be called once your element is no longer connected”[0], and i
understood it to mean that the connected and disconnected callbacks
could be called our of order, thus it would be possible to add event
listeners that would not be removed—again.
I am not actually sure where i have to do the same for the rest of the
“internal” events.

This is mainly because i sometimes think that the tag is accepted just
because it is there in the input, but actually it is not being used at
all. I fear more people would do the same mistake.
This makes reload only the <main> portion of the page, instead of the
whole thing, which to me looks faster; haven’t really measured it.
Like with duplicate, i had to add the location query argument when
inside the view page in order to return back to the same page, not the
index.
Had to add a new hidden field to the form to know whether, when the
request is HTMx-triggered, to refresh the page, as i do when duplicating
from the index, or redirect the client to the new invoice’s view page,
but only if i was duplicating from that same page, not the index.
Since i now have to target main when redirecting to the view page, so
i had to add a location structure with the required json fields and all
that, when “refreshing” i actually tell HTMx to open the index page
again, which seems faster, now that i am used to boosted links.
Changed the invoice number field’s type to search to add the delete icon
on Chromium. Firefox does not add that icon, but i do not care; it is
still better that type="text".
Had to emit the change event to the numerus-tag field, otherwise the
form would not detect the change.
I also can not use keyup as a trigger because the changed modifier can
not be used in the <form>, as nothing ever changes, i do not know how to
trigger the form from children (i.e., data-hx-trigger on the <input>
does nothing), and i can not trigger for just any keyup, or i would
make the request even if they only moved the cursor with the arrow keys,
which is very confusing as Firefox resets the position (this may be due
the fact that i reload the whole <main>, but still).
