Document how to handle plurals (for translators and developers)

[hadley]

Seems like it would be useful to include this somewhere?

```R library(rvest) html <- read_html("https://l10n.gnome.org/teams/") teams <- html %>% html_nodes(".column_container li > a") %>% html_attr("href") urls <- paste0("https://l10n.gnome.org", teams) find_plural_form <- function(url) { print(url) url %>% read_html() %>% html_node("#content > div > p") %>% html_text() } forms <- sapply(urls, find_plural_form) names(forms) <- teams %>% gsub("^/teams/", "", .) %>% gsub("/$", "", .) split(names(forms), forms) ``` ``` $`Plural forms: nplurals=1; plural=0` [1] "hy" "zh_CN" "zh_trad" "dz" "ka" "id" "ja" "kk" [9] "km" "ky" "ko" "lo" "ms" "fa" "th" "tr" [17] "ug" "vi" $`Plural forms: nplurals=1; plural=0;` [1] "my" "bo" $`Plural forms: nplurals=2; plural= n==1 || n%10==1 ? 0 : 1` [1] "mk" $`Plural forms: nplurals=2; plural=(n != 1)` [1] "ab" "af" "sq" "an" "ast" "az" "eu" "bn" "brx" "bg" [11] "ca" "ckb" "nhn" "da" "nl" "eo" "et" "fi" "fy" "fur" [21] "gl" "de" "el" "gu" "ht" "ha" "he" "hi" "hu" "it" [31] "mjw" "ml" "mr" "es_MX" "mn" "ne" "nso" "no" "or" "os" [41] "ps" "pt" "pa" "es" "sw" "sv" "tg" "ta" "te" "tk" [51] "ur" "guc" $`Plural forms: nplurals=2; plural=(n != 1);` [1] "en_AU" "en_GB" "en_CA" "fo" "ts" $`Plural forms: nplurals=2; plural=(n !=1)` [1] "nds" $`Plural forms: nplurals=2; plural=(n % 10 == 1 && n % 100 != 11) ? 0 : 1;` [1] "quz" $`Plural forms: nplurals=2; plural=(n % 100 != 1 && n % 100 != 21 && n % 100 != 31 && n % 100 != 41 && n % 100 != 51 && n % 100 != 61 && n % 100 != 71 && n % 100 != 81 && n % 100 != 91)` [1] "is" $`Plural forms: nplurals=2; plural=(n > 1)` [1] "ak" "am" "pt_BR" "fr" "ia" "mg" "mi" "oc" "wa" $`Plural forms: nplurals=2; plural=(n > 1);` [1] "ln" $`Plural forms: nplurals=2; plural=(n!= 1)` [1] "ku" $`Plural forms: nplurals=2; plural=(n!=1)` [1] "kn" $`Plural forms: nplurals=2; plural=n != 1` [1] "so" $`Plural forms: nplurals=2; plural=n != 1;` [1] "lg" $`Plural forms: nplurals=2; plural=n>1` [1] "kab" $`Plural forms: nplurals=2;plural=(n>1);` [1] "kg" $`Plural forms: nplurals=3; plural=(n%10==1 && n%100!=11 ? 0 : n != 0 ? 1 : 2)` [1] "lv" $`Plural forms: nplurals=3; plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 && (n%100<10 || n%100>=20) ? 1 : 2)` [1] "lt" $`Plural forms: nplurals=3; plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2)` [1] "be" "bs" "hr" "ru" $`Plural forms: nplurals=3; plural=(n==1 ? 0 : (n==0 || (n%100 > 0 && n%100 < 20)) ? 1 : 2);` [1] "ro" $`Plural forms: nplurals=3; plural=(n==1 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2)` [1] "pl" "szl" $`Plural forms: nplurals=3; plural=(n==1) ? 0 : (n>=2 && n<=4) ? 1 : 2` [1] "cs" $`Plural forms: nplurals=3; plural=(n==1) ? 1 : (n>=2 && n<=4) ? 2 : 0` [1] "sk" $`Plural forms: nplurals=3; plural=n == 1 ? 0 : (n == 2 ? 1 : 2);` [1] "gv" $`Plural forms: nplurals=4; plural= (n==1) ? 0 : (n==2) ? 1 : (n != 8 && n != 11) ? 2 : 3` [1] "cy" $`Plural forms: nplurals=4; plural=(n%100==1 ? 1 : n%100==2 ? 2 : n%100==3 or n%100==4 ? 3 : 0) ` [1] "sl" $`Plural forms: nplurals=4; plural=(n==1 || n==11) ? 0 : (n==2 || n==12) ? 1 : (n > 2 && n < 20) ? 2 : 3;` [1] "gd" $`Plural forms: nplurals=4; plural=n==1 ? 3 : n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2` [1] "uk" $`Plural forms: nplurals=4; plural=n==1? 3 : n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2` [1] "sr" $`Plural forms: nplurals=5; plural=n==1 ? 0 : n==2 ? 1 : n<7 ? 2 : n<11 ? 3 : 4` [1] "ga" $`Plural forms: nplurals=6; plural= n==0 ? 0 : n==1 ? 1 : n==2 ? 2 : n%100>=3 && n%100<=10 ? 3 : n%100>=11 && n%100<=99 ? 4 : 5;` [1] "ar" $`Plural forms: Unknown` [1] "as" "bal" "bem" "bn_IN" "br" "crh" "dv" "ff" [9] "gn" "io" "az_IR" "ks" "rw" "la" "li" "mai" [17] "ang" "en@shaw" "si" "tl" "tt" "uz" "xh" "yi" [25] "yo" "zu" ```

There is this:

and

Could you elaborate what you'd want as input/output here?

[hadley]

I think what I want is a write up of how to handle plurals from the developer perspective (i.e. plurals in languages are more complicated than you might thinks), and the translator perspective (i.e. here the definition of the pluralisation system for your language, and how you need to order the translations).
