Support Swedish numbers (code provided)

[fredrikpaues]

This is my attempt at an fc-swedish.def. I started with a Python script (at the bottom), which I then converted to LaTeX code that draws heavily on fc-german.def. From my tests it works for numbers 0-99,999 for all genders and for \FCordinal, ordinalnumber, \Ordinalnumber, \ORDINALnumber, \numberstring, \Numberstring, and \NUMBERstring.

My primary concern is that the feminine is default when forming ordinal numbers. Is there some way to change this just for swedish?

Other than that, would you need anything more from me to implement this in the package?

[fredrikpaues]

I managed to figure out how to coerce fmtcount into using my fc-swedish.def.

[fredrikpaues]

I've managed to incorporate settings into fc-swedish.def.

The settings

The settings are

• one which determines if "ett" (Swedish for "one") should be included for in front of "hundra" ("hundred") and "tusen" (thousand) whereby numbers such as 100, 1,000 and 1,100 are written as
  • "hundra", "tusen" and "tusenhundra" (one=neither --- the default)
  • "etthundra", "tusen" and "tusenetthundra" (one=hundred)
  • "hundra", "ettusen" and "ettusenhundra" (one=thousand)
  • "etthundra", "ettusen" and "ettusenetthundra" (one=both)
• space which determines if there should be space before and after the word "tusen" ("thousand") whereby a number such as 5,100 is written as
  • "femtusenhundra" (space=neither)
  • "femtusen hundra" (space=after)
  • "fem tusen hundra" (space=both)

I have intentionally left out the option space=before as that to the best of my knowledge is never done.

Also note that the two options interact. When one is set to either neither or hundred, there is nothing in front of "tusen" and so a number such as 1,000 will be written as "tusen" regardless of the value of space. (A number such as 21,000 will of course still be written as "tjugoen tusen" when space is set to both.)

Usage

As language options are only set up for the built-in languages (as noted in #48), a custom language such as Swedish seems to require some massaging. I've gotten it to work with the following setup.

\documentclass[swedish]{article}
\usepackage{babel}
\usepackage{fmtcount}
\FCloadlang{swedish}
\makeatletter
\define@key{fmtcount}{swedish}[]{%
  \setkeys{fcswedish}{#1}%
}
\define@key{fcswedish}{fmtord}{%
  \ifthenelse{\equal{#1}{raise}\or\equal{#1}{level}}{%
    \expandafter\let\expandafter\@tempa\csname fc@set@ord@as@#1\endcsname
    \expandafter\@tempa\csname fc@ord@swedish\endcsname
  }{%
    \ifthenelse{\equal{#1}{undefine}}{%
      \expandafter\let\csname fc@ord@swedish\endcsname\undefined
    }{%
      \PackageError{fmtcount}%
      {Invalid value `#1' to fmtord key}%
      {Option `fmtord' can only take the values `level', `raise'
        or `undefine'}%
    }
  }
}
\makeatother
