Language

On this page

A language (ISO 639-1), written as its code, en; form: CodeForm.alpha3 writes ISO 639-2's eng. Language.or_ is Odia.

Places; not ordered; since Jadpo 0.1.0.

Make one

Pick one of its variants, Language.aa.

text.parse(raw, as: Language) reads one from its text; text that isn't one at all fails malformed, such as eng, en-GB or english.

Variants

188 variants, each with the code its text is written in. aa (aa), ab (ab), ae (ae), af (af), ak (ak), am (am), an (an), ar (ar), as (as), av (av), ay (ay), az (az), ba (ba), be (be), bg (bg), bi (bi), bm (bm), bn (bn), bo (bo), br (br), bs (bs), ca (ca), ce (ce), ch (ch), co (co), cr (cr), cs (cs), cu (cu), cv (cv), cy (cy), da (da), de (de), dv (dv), dz (dz), ee (ee), el (el), en (en), eo (eo), es (es), et (et), eu (eu), fa (fa), ff (ff), fi (fi), fj (fj), fo (fo), fr (fr), fy (fy), ga (ga), gd (gd), gl (gl), gn (gn), gu (gu), gv (gv), ha (ha), he (he), hi (hi), ho (ho), hr (hr), ht (ht), hu (hu), hy (hy), hz (hz), ia (ia), id (id), ie (ie), ig (ig), ii (ii), ik (ik), in_ (in), io (io), is (is), it (it), iu (iu), iw (iw), ja (ja), ji (ji), jv (jv), jw (jw), ka (ka), kg (kg), ki (ki), kj (kj), kk (kk), kl (kl), km (km), kn (kn), ko (ko), kr (kr), ks (ks), ku (ku), kv (kv), kw (kw), ky (ky), la (la), lb (lb), lg (lg), li (li), ln (ln), lo (lo), lt (lt), lu (lu), lv (lv), mg (mg), mh (mh), mi (mi), mk (mk), ml (ml), mn (mn), mo (mo), mr (mr), ms (ms), mt (mt), my (my), na (na), nb (nb), nd (nd), ne (ne), ng (ng), nl (nl), nn (nn), no (no), nr (nr), nv (nv), ny (ny), oc (oc), oj (oj), om (om), or_ (or), os (os), pa (pa), pi (pi), pl (pl), ps (ps), pt (pt), qu (qu), rm (rm), rn (rn), ro (ro), ru (ru), rw (rw), sa (sa), sc (sc), sd (sd), se (se), sg (sg), si (si), sk (sk), sl (sl), sm (sm), sn (sn), so (so), sq (sq), sr (sr), ss (ss), st (st), su (su), sv (sv), sw (sw), ta (ta), te (te), tg (tg), th (th), ti (ti), tk (tk), tl (tl), tn (tn), to (to), tr (tr), ts (ts), tt (tt), tw (tw), ty (ty), ug (ug), uk (uk), ur (ur), uz (uz), ve (ve), vi (vi), vo (vo), wa (wa), wo (wo), xh (xh), yi (yi), yo (yo), za (za), zh (zh), zu (zu).

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

Text JSON
en "en"
iw "iw"
ja "ja"
or "or"

It is stored in one column named for the field, of type text. ja is stored as 'ja'.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Value Shown
en English
iw Hebrew
ja Japanese
or Odia

Operations

It has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
