Format strings

[Leandro Matos]

How could I use sprintf-js to format strings that should be translated? Can you help me?

First you need to pass sprintf-js to the plugin function like so:

var pugPipe = pug({
  i18n: {
    locales: 'locale/*',
    filename: '{{basename}}.{{lang}}.html'
  },
  data: {
    sprintf: require('sprintf-js')
  },
});

gulp.src('input/*.pug')
  .pipe(pugPipe)
  .pipe(gulp.dest('output/'))

Then you can use sprintf function inside Pug:

h1 Hello World
h2 #{ sprintf($i18n.baseString, $i18n.variable1, $i18n.variable2) }

An error occoured =( sprintf is not a function

Because require('sprintf-js') is an object and has sprintf() function inside.

data: {
  sprintf: require('sprintf-js').sprintf
}

You should know what module contains, not me :)
