What is the idiomatic Go equivalent of C's ternary operator? -


in c/c++ (and many languages of family), common idiom declare , initialize variable depending on condition uses ternary conditional operator :

int index = val > 0 ? val : -val

go doesn't have conditional operator. idiomatic way implement same piece of code above ? came following solution, seems quite verbose

var index int  if val > 0 {     index = val } else {     index = -val }

is there better ?

as pointed out (and unsurprisingly), using if+else indeed idiomatic way conditionals in go.

in addition full blown var+if+else block of code, though, spelling used often:

index := val if val <= 0 {     index = -val }

and if have block of code repetitive enough, such equivalent of int value = <= b ? : b, can create function hold it:

func min(a, b int) int {     if <= b {         return     }     return b }  ...  value := min(a, b)

the compiler inline such simple functions, it's fast, more clear, , shorter.

sequelize.js - Sequelize: sort by enum cases -

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
