javascript - Gulp. Compile all .jade files when child (_*.jade) included -

i have next structure:

jade ├── _skeleton.jade ├── _header.jade ├── _footer.jade | ├── includes │ └── _include-on-index.jade │ └── _include-on-page-1.jade │ └── _include-on-all-pages.jade | ├── pages │ └── index.jade │ └── page-1.jade │ └── page-2.jade │ └── page-3.jade 

and need setup jade compile, apps, (for example prepros).

it means if edit page-3.jade need compile page-3.jade, if edit file start _.jade, don`t need compile exectly _.jade file html, need compile .jade files included _*.jade file

for example when edit file _header.jade, need compile files included _header.jade, if edit _include-on-index.jade need compile file without _ included _include-on-index.jade

i`m trying module gulp-jade-find-affected, works incorrect, , compile files start _*.jade html.

here gulpfile.js:

var gulp = require('gulp'),     jade = require('gulp-jade'),     watch = require('gulp-watch'),     affected = require('gulp-jade-find-affected');  gulp.task('watch-jade', function () {   '!sources/jade/_*.jade'   watch('sources/jade/*.jade')       .pipe(affected())       .pipe(jade())       .pipe(gulp.dest('site')); });  gulp.task('default', ['watch-jade']); 

maybe have gulp task , can me ?
