VS 2015 Use Gulp to Compile Less -

i trying set similar process web essentials offered in old visual studio in newest one. of aren't familiar how worked, process was:

file setup:     a.less         a.css             a.min.css             a.css.map       b.less         b.css             b.min.css             b.css.map 

so when open a.less , start editing it, automatically check out a.css, a.min.css, , a.css.map well. when save, recompile 3 sub files saving less file.

i able replicate writing separate task each file so:

gulp.task('checkout', function () {     return gulp.src('styles/brands.css')         .pipe(tfs()); });   gulp.task('less', ['checkout'], function () {     del('styles/brands.css');      return gulp.src('styles/brands.less')         .pipe(less())         .pipe(gulp.dest('styles')); }); 

this uses gulp-tfs-checkout checkout sub file, , less compile. works 100% how expect to. can set watch watch less task , work great. problem is, how expand handle less files in folder? write separate checkout , compile tasks each file, that's not ideal.

i used writing projects saving less file compiles , concats of them single or couple files, work project , multiple reasons need keep css files separate now. use visual studio's bundling, older project , people have referenced css files randomly outside of bundling process pretty big/risky task change that.

i don't know how watch many files, change current 1 if makes sense.

gulp.task('less', function () {     return gulp.src('styles/*.less') //watch of files         .pipe(tfs())//checkout css file less file changed here somehow         .pipe(less()) //compile css file changed         .pipe(gulp.dest('styles')); }); 

i used grunt , gulp, said things in bulk on project. i'm not sure how when want watch files, change 1

why don't create tasks per each file dynamically? can read contents of folder less files fs.readdirsync , if file less file create each task 'checkout' + filename , 'less' + filename.
being dynamically not have problems when create new less file or when remove one.
