It works better than with the weird hover behaviour i could do in CSS,
and it already has most of the aria roles needed.
The only tricky part is to allow closing it by clicking anywhere else,
that is done by “extending” the <summary> to the whole screen, with a
lower z-index than the menu but higher than the rest of controls, that
way we force people to click on that summary.
Had to call xgettext on Go source files because now the title comes from
there, as i assume i will have titles like "Invoice #INVxxxx" that have
to come from the database that the template does not know.
Since users do not have access to the auth scheme, i had to add a view
that selects only the data that they can see of themselves (i.e., no
password or cookie).
I wanted to use the `request.user.id` setting that i set in
check_cookie, but this would be bad because anyone can change that
parameter and, since the view is created by the owner, could see and
*change* the values of everyone just by knowing their id. Thus, now i
use the cookie instead, because it is way harder to figure out, and if
you already have it you can just set to your browser and the user is
fucked anyway; the database can not help here.
I **am** going to use the user id in row level security policies, but
not the value coming for the setting but instaed the one in the
`user_profile`, since it already is “derived” from the cookie, that’s
why i added that column to the view.
The profile includes the language, that i do not use it yet to switch
the locale, so i had to add a relation of the available languages, for
constraint purposes. There is no NULL language, and instead i added the
“Undefined” language, with ‘und’ tag’, to represent “do not know/use
content negotiation”.
The languages in that relation are the same i used to have inside
locale.go, because there is no point on having options for languages i
do not have the translation for, so i now configure the list of
available languages user in content negotiation from that relation.
Finally, i have added all font from RemixIcon because that’s what we
used in the design and i am going to use quite a lot of them.
There is duplication in the views; i will address that in a different
commit.
I had to choose between [1], [2], and [3].
As far as i could find, [1] is not easy to work with templates[4] and at
the moment is not maintained[5].
Both [2] and [3] use the same approach to be used from within templates:
you have to define a FuncMap with template functions that call the
message catalog. Also, both libraries seems to be reasonably
maintained, and have packages in Debian’s repository.
However, [2] repeats the same mistakes that POSIX did with its
catalogs—using identifiers that are not the strings in the source
language—, however this time the catalogs are written in JSON or YAML!
This, somehow, makes things worse….
[3], the one i settled with, is fine and decently maintained. There are
some surprising things, such as to be able to use directly the PO file,
and that it has higher priority over the corresponding MO, or that the
order of parameters is reversed in respect to gettext. However, it uses
a saner format, and is a lot easier to work with than [3].
The problem, of course, is that xgettext does not know how to find
translatable strings inside the template. [3] includes a CLI tool
similar to xgettext, but is not a drop-in replacement[6] and does not
process templates.
The proper way to handle this would be to add a parser to xgettext, but
for now i found out that if i surround the call to the translation
functions from within the template with parentheses, i can trick
xgettext into believing it is parsing Scheme code, and extracts the
strings successfully—at least, for what i have tried. Had to add the
keyword for pgettext, because Schemed does not have it, but at least i
can do that with command line parameters.
For now i left only Spanish and Catalan as the two available languages,
even though the source text is written in English, because that way i
can make sure i do not leave strings untranslated.

At first i thought that i would need to implement sessions, the ones
that keep small files onto the disk, to know which user is talking to
the server, but then i realized that, for now at least, i only need a
very large number, plus the email address, to be used as a lookup, and
that can be stored in the user table, in a separate schema.
Had to change login to avoid raising exceptions when login failed
because i now keep a record of login attemps, and functions are always
run in a single transaction, thus the exception would prevent me to
insert into login_attempt. Even if i use a separate procedure, i could
not keep the records.
I did not want to add a parameter to the logout function because i was
afraid that it could be called from separate users. I do not know
whether it is possible with the current approach, since the settings
variable is also set by the same applications; time will tell.
This is a very rough test to actually check the login function outside
pgTAP; it is very ugly, in both design and code, and (i hope) does not
reflect future quality.
I was about to use Echo[0] as a “web framework”, but something feels
wrong when using a framework with Go—i do not know what. I actually
tried it and was even more put off by the JSON-formatted logger that can
not be disabled; i was already losing control of the application!
I created the folder following the apparently de facto guidelines for Go
projects, and i see no problem with mixing Go’s folders with Sqitch’s:
both are part of the same application and there are not conflicts.
