plural2R: plural2R

In sigbertklinke/gettext: Implements Localization of Texts Similar to 'GNU gettext'

Description

Converts a plural from from text to list with the input text, nplurals value and a R function plural(n) which computes the plural index from n.

• Note 1: The index is increased by one since R starts with x[1] and C with x[0]

• Note 2: Only a subset of C symbols are supported based on the test cases: (, ), %, <, >, >=, <=, &&, ||, ?:, =, and ;.

Usage

plural2R(ctxt)

Arguments

ctxt	character: one string with a plural form

Value

list with the input text, nplurals value and a R function plural(n)

Examples

# Belarusian plural form
p <- paste0('nplurals=3;',
     'plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);')
l <- plural2R(p)
l$nplurals
l$plural(0:100)
