handlebars.js - How to get gulp-handlebars to recognize partials -

i having trouble getting handlebars locate partials. have nested folder structure looks following:

some/local/path/handlebars/shared/_shared.hbs some/local/path/handlebars/nested/template1.hbs some/local/path/handlebars/nested/template2.hbs 

i thought default handlebars supposed mark files start underscore partial, i'm not seeing calls "registerpartials" in output. below last modification i've made gulp task. can't seem figure out how debug - maybe i've been staring @ long.

gulp.task('template', function() {     return gulp.src(paths.templates)         .pipe(handlebars())         .pipe(wrap('handlebars.template(<%= contents %>)'))         .pipe(declare({             namespace: 'myapp.templates',             noredeclare: true,             processname: function(filepath) {                 return somefunction(filepath);             }         }))         .pipe(concat('templates.js'))         .pipe(gulp.dest('output/path')); }); 

my paths.templates variable set this:

some/local/path/handlebars/**/*.hbs 

any idea i'm doing wrong here? also, out of curiosity (and maybe part of problem), there purpose processname outside of generating namespace?

thanks in advance help!
