Scala DSL: How to omit parentheses from apply call? -


i wrote small library units of measure (yes, use squants this, need features squants not provide). unit class unitofmeasure , quantity, i.e., number , unit, quantity.

suppose defined m unitofmeasure, want write like:

val q = 3.0 m

i created class quantitywrapper in package object so:

implicit class quantitywrapper[t](value: t)(implicit num: numeric[t]) {    def apply(unit: unitofmeasure[t]): quantity[t] =     quantity(value, unit) }

so can do:

val q = 3.0(m)

because 3.0 implicitly converted quantitywrapper[double] , m defined unitofmeasure[double].

but want able omit parentheses. possible without defining methods in quantitywrapper every unit have?

is possible without defining methods in quantitywrapper every unit have?

no. whatever do, 3.0 m parsed (3.0).m, there must exist method m on double (possibly through implicit conversion).

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
