jordi fita mas 82eb8a2733 Start the tag input custom element
This is more or less the same as a multiselect, except that now it
adds a list of string element that you write into the search element.

It is supposed to fetch a list of tag suggestions from the server, but i
have not implemented it yet.

jordi fita mas 8efae0485e Add the edit form for invoices
I had to change the way /invoices/new and /invoices/batch are handled,
because httprouter was not happy with the new POST /invoices/:slug/edit
route, claiming that /invoices/:slug conflicts with the previously
existing routes.

I also could not make it work with the PATCH method, even though i
correctly added the patchMethod override function, therefore editing
invoices is also weird because i have to take into account the “quick”
invoice status change.

I use the same form for both new and edit invoices, because the only
changes are that we can not edit the invoice date and number, by
Oriol’s design, but must be able to change the status; very similar
forms.

jordi fita mas 2bc05e948c Add invoice tags
I followed the same restrictions as Gitea’s topics, arbitrarily, because
if it is enough for repositories it should be for invoices too,
apparently.

As per the design document.

jordi fita mas 0c8edb9cae Add option to duplicate an invoice
With Oriol we agreed that a duplicate is just the new invoice form
prefilled with the data from another invoices, but without the number or
the date.

jordi fita mas 31ef3ea47a Add company’s default payment method
I had to use a deferrable foreign key because the payment methods have
a reference to the company, and the company now a circular reference to
payment method.

jordi fita mas d6034ad732 Add discount and tax classes columns to invoice
This was actually the (first) reason we added the tax classes: to show
them in columns on the invoice—without the class we would need a column
for each tax rate, even though they are the same tax.

The invoice design has the product total with taxes at the last column,
above the tax base, that i am not so sure about, but it seems that it
has not brought any problem whatsoever so far, so it remains as is.

Had to reduce the invoice’s font size to give more space to the table
or the columns would be right next to each other.  Oriol also told me
to add more vertical spacing to the table’s footer.

jordi fita mas 4d2379555e Convert invoices to PDF with WeasyPrint
Although it is possible to just print the invoice from the browser, many
people will not even try an assume that they can not create a PDF for
the invoice.

I thought of using Groff or TeX to create the PDF, but it would mean
maintaining two templates in two different systems (HTML and whatever i
would use), and would probably look very different, because i do not
know Groff or TeX that well.

I wish there was a way to tell the browser to print to PDF, and it can
be done, but only with the Chrome Protocol to a server-side running
Chrome instance.   This works, but i would need a Chrome running as a
daemon.

I also wrote a Qt application that uses QWebEngine to print the PDF,
much like wkhtmltopdf, but with support for more recent HTML and CSS
standards.  Unfortunately, Qt 6.4’s embedded Chromium does not follow
break-page-inside as well as WeasyPrint does.

To use WeasyPrint, at first i wanted to reach the same URL as the user,
passing the cookie to WeasyPrint so that i can access the same invoice
as the user, something that can be done with wkhtmltopdf, but WeasyPrint
does not have such option.  I did it with a custom Python script, but
then i need to package and install that script, that is not that much
work, but using the Debian-provided script is even less work, and less
likely to drift when WeasyPrint changes API.

Also, it is unnecessary to do a network round-trip from Go to Python
back to Go, because i can already write the invoice HTML as is to
WeasyPrint’s stdin.

jordi fita mas 419ac3ed46 Adjust invoice.css to work with WeasyPrint too
I am planning to use WeasyPrint to “generate PDF” from the same HTML
that the user view, but it seems that it does not support flex’s gap
and some other properties that i had to change to work in both user
agents.

I also moved the invoice’s “footer” inside the last product’s body
because i do not want the footer to be a “widow”.

jordi fita mas 18fba2964f Add invoice view, with print CSS
Had to group name and description rows in tbody because i do not want
to break them on pagination.

I also could not use tfoot for subtotal, taxes, and total because then
they appear on every page.

The disclaimer should appear only at the very bottom of the last page,
but i do not know how to do that; using position fixed shows it on
every page.

jordi fita mas 8dbf8ef2d0 Add currency_pattern to language relation
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.

jordi fita mas 97ef02b0f9 Add views to compute taxes and total amount of invoices
They are not functions because i need to join them with the main
invoice relation, and although possible is a bit more awkward with
functions.

The taxes have their own relation because i will need them grouped by
their name in the PDF, so it will probably be a select for that
relation.

jordi fita mas c1e443e3bc Move the new product description before the taxes
Because in the “default view” that position has a lot of space that is
best used by a large text area than a simple number input.

jordi fita mas 045bf7ff6a Add the formnovalidate attribute to update and add products buttons
They are to complete the invoice, so it can be in an invalid date, but
we do not want to force people to finish all required inputs before they
can add products or update quantities, do we?

Now had to add the empty option label for customer in all cases, because
it could be empty, although that should be done regardless in case
someone has a browser that does not validate fields.

jordi fita mas 4903c8a3b9 Add the form to add products to an invoice and create invoices too
Still missing: the invoice number, that requires more tables and
possibly a PL/pgSQL function to do it properly.
