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.
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.
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.
Had to add the editProductPage because now i need to know the slug in
order to build the form’s action link. I also added the `ProductName`
field because it was less awkward than using `.Form.Name` everywhere.
With Oriol we agreed that products should have tags, too, and that the
“tag pool”, as it were, should be shared with the one for invoices and
contacts.
Had to add the `company_id` attribute in the `using` clause for `tag` in
`MustFillFromDatabase`, even though it’s not strictly necessary, because
then PostgreSQL does not know which `company_id` attribute use for the
join with `company`—the one from `product` or the one from `tag`.
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.
The design calls for rendering all amounts with their currency symbol,
but golang.org/x/text’s currency package always render the symbol in
front, which is wrong in Catalan and Spanish, and a lot of other
languages.
Consulting the Internet, the most popular package for that is
accounting[0], which is almost as useless because they confuse locale
with the currency’s country of origin’s “usual locale” (e.g., en-US for
USD), which is also wrong: in Catalan i need to write USD prices as
"1.234,56 $" regardless of what Americans do.
With accounting i have the recourse of initializing the struct that
holds all the “locale” information, which is also wrong because i have
to define the decimal and thousands separators, something that depends
only on the locale, next to the currency’s precision, that is
locale-independent. But, since all CLDR data from golang.org/x/text
is inside an internal package, i can not access it and would need to
define all that information myself, which defeats the purpose of using
an external package.
Since for now i only need the format pattern for currency, i just saved
it into the database of available languages, that i do not expect to
grow too much.

I do not want to use floats in the Go lang application, because it is
not supposed to do anything with these values other than to print and
retrieve them from the user; all computations will be performed by
PostgreSQL in cents.
That means i have to “convert” from the price format that users expect
to see (e.g., 1.234,56) to cents (e.g., 123456) and back when passing
data between Go and PostgreSQL, and that conversion depends on the
currency’s decimal places.
At first i did everything in Go, but saw that i would need to do it in
a loop when retrieving the list of products, and immediately knew it was
a mistake—i needed a PL/pgSQL function for that.
I still need to convert from string to float, however, when printing the
value to the user. Because the string representation is in C, but i
need to format it according to the locale with golang/x/text. That
package has the information of how to correctly format numbers, but it
is in an internal package that i can not use, and numbers.Digit only
accepts numeric types, not a string.
