stylus string interpolation styntax for :before pseudo selector using a for loop -

i'm trying make

#others li .text1:before{     content: "text1"; }...

by doing

#others li     label in text1 text2 text3         .{label}:before             content {label}

but syntax isn't right seems... gives error

expected "indent", got "outdent"

the error content {label} bit, because without class selectors (.text1:before) prints ok

and content '{label}' prints out {label} is.

stylus don't have interpolation in strings or idents values, use addition string, convert ident string:

#others li     label in text1 text2 text3         .{label}:before             content ''+label
