Install – Instalar

$ sudo gem install estem

$ gem install estem

Usage

As a reminder, take in consideration that the Spanish language has several non US-ASCII characters, and because of that, the same data may varied from one codeset to another.

Please remember to use a UTF-8 compatible encoding while using EStem. Please do not use String#force_encoding to convert from one codeset to another, you may try using String#encode alone but, instead, consider using String#safe_es_stem when handling incompatibles codesets or the codeset type varies.

require 'estem'

puts "albergues".es_stem      # ==> "alberg"
puts "habitaciones".es_stem   # ==> "habit"

# EStem will never make unnecessary changes to your input data.
puts "ALbeRGues".es_stem      # ==> "ALbeRG"
puts "HaBiTaCiOnEs".es_stem   # ==> "HaBiT"
puts "Hacinamiento".es_stem   # ==> "Hacin"

Uso

Como recordatorio, ten en cosideración que el Castellano posee muchos carácteres que están fuera del código ASCII, y por esta razón, los datos pueden variar de un conjunto de codificación a otro.

Por favor recuerda utilizar sistemas de condificación compatibles con UTF-8 cuando se trabaje con EStem. Por favor no use String#force_encoding para convertir de un conjunto de codificación a otro, podría utilizar String#encode solo, pero en su lugar, considere utilizar String#safe_es_stem() si está manejando conjuntos de codificación incompatibles o se desconoce el tipo.

require 'estem'

puts "albergues".es_stem      # ==> "alberg"
puts "habitaciones".es_stem   # ==> "habit"

# EStem nunca hará cambios innecesarios a tus datos.
puts "ALbeRGues".es_stem      # ==> "ALbeRG"
puts "HaBiTaCiOnEs".es_stem   # ==> "HaBiT"
puts "Hacinamiento".es_stem   # ==> "Hacin"
