do I understand this wrong or is something not right here?
I have this piece of code
gulp.task("minifyScripts", function () {
return gulp.src("assets/scripts/*.js")
.pipe(uglify())
.pipe(rev())
.pipe(gulp.dest('assets/scripts/min'))
.pipe(rev.manifest())
.pipe(revDel())
.pipe(gulp.dest('assets/scripts'))
.pipe(livereload())
.pipe(browserSync.stream());
});
My understanding was that this should remove old .js file when one with new hash is created, but its not...
Do you have any idea? Thanks so much!
You need to specify either dest in the options, or base in the manifest options—unless you're writing everything to the root directory.
Try:
pipe(revDel({dest: "assets/scripts/min"})
Seems that rev-del has a number of users, including myself, who are unable to get the plug-in to delete the old static files after gulp-rev hashes them.
Switching over to gulp-rev-delete-original simply worked OOB.
In the OP's use case, the updated solution would be:
const revDel = require("gulp-rev-delete-original")
gulp.task("minifyScripts", function () {
return gulp.src("assets/scripts/*.js")
.pipe(uglify())
.pipe(rev())
.pipe(revDel()) // call just after rev()
.pipe(gulp.dest('assets/scripts/min'))
.pipe(rev.manifest())
//.pipe(revDel()) ==> move to just after rev()
.pipe(gulp.dest('assets/scripts'))
.pipe(livereload())
.pipe(browserSync.stream());
});

I'm trying to ignore a folder within a gulp task, but it doesn't seem to work.
Here are the different tests I have done: all without success: the files are copied into the destination folder.
gulp.task('dev', function () {
return gulp.src([
//sources
'./src/**/*',
// first test
'!src/*views/*',
// second test
'!src/**views/'
])
.pipe(cleanDest('./dev/'))
//destination
.pipe(gulp.dest('./dev/'));
});
Has anyone of you ever encountered the problem and managed to work around it / solve it?
Thank you in advance for your help
Assuming they are .js files the below works for me:
return gulp.src(['./src/!(*views)/*.js'])
this will ignore the folder views.
gulp.task('dev', function () {
return gulp.src(['./src/**/*', '!src/**/views'])
.pipe(cleanDest('./dev/'))
.pipe(gulp.dest('./dev/'));
});
I have a gulp-watch script that watches for changes in my image directory then process the images. The problem is that photoshop save for web is putting temp files in the directory and then renaming them very quickly, which trips up my image processing script. I would like to exclude them from the watch script.
The temp files are formatted as so moog-mftrem_tmp489245944
I would like to use the _tmp string to exclude, but not sure how to exclude characters in the middle of a file name. Here is what I have tried but doesn't seem to work:
gulp.task('watch', function() {
gulp.watch(['app/images/pedals/*.png','!app/images/pedals/*_tmp*'], ['images']);
});
Thanks for any help!
While your temp files don't have extensions, glob paths don't know what to do if you don't specify one. It becomes merely a path to a folder, and indeed it doesn't find a folder name matching your glob.
Try:
gulp.task('watch', function() {
gulp.watch(['app/images/pedals/*.png','!app/images/pedals/*_tmp*.*'], ['images']);
});
Note the extra: .* (period asterisk)
For completeness I like to add the recursive globstar /**/
i.e.
gulp.task('watch', function() {
gulp.watch(['app/images/pedals/**/*.png','!app/images/pedals/**/*_tmp*.*'], ['images']);
});
consider using 'gulp-filter' :
const gulp = require('gulp');
const filter = require('gulp-filter');
gulp.task('watch', function() {
gulp.watch('app/images/pedals/*.png', ['images']);
});
const f = filter(file => file.path.includes('tmp'));
gulp.task('images', function() {
return gulp.src('app/images/pedals/*.png')
.pipe(f)
.pipe(gulp.dest('./build'))
});
I have a gulp task to uglify my JS:
gulp.task('uglify', ['eslint'], () => {
return gulp.src(jsDest + '/*.js')
.pipe(rename({suffix: '.min'}))
.pipe(stripDebug())
.pipe(uglify())
.pipe(gulp.dest(jsDest));
});
It works fine, but as I am using a wildcard to identify JS files, I end up with new files named name.min.min.js rather than existing minified files being overwritten.
A work around I have come up with is to have an additional task which cleans out these files before I uglify again:
gulp.task('cleanUglified', () => {
return del.sync('dist/js/*.min.js');
});
gulp.task('uglify', ['cleanUglified', 'eslint'], () => {
...
});
While this works fine, I'm sure there must be a way to have my task ignore anything named *.min* and in fact overwrite any that already exist.
Solved - I can ignore the already minified files and overwrite them by using this pattern to select the files to uglify:
return gulp.src(jsDest + '/*[^.min].js')
EDIT
Following the below comments, I have updated to:
return gulp.src(['*.js', '!*.min.js'])
I have the following code:
gulp.task('watch:Feature', function() {
gulp.watch(['./js/Feature/**/*.ts', '!./js/Feature/.gulp-tsc-tmp*.ts'], function () { console.log("Test"); });
});
I've substituted my typescript build task for console.log("Test") and am copying a file with the name: .gulp-tsc-tmp-1151023-9976-e1a1h3.ts into the Feature directory, which causes "Test" to be output to the console.
I've tried all sorts of exclude patterns including specifying the exact filename I'm copying into the directory, none of which seem to work.
What would be the correct way of ignoring files with a particular prefix?
I encountered this a few weeks back and was informed that feature was removed, I didn't have time to establish if that was true but certainly none of my previously working 'ignores' were working on updated release.
The correct way to ignore files in a watch in gulp 4 is this:
gulp.watch('js/Feature/**/*.ts', {
ignored: 'js/Feature/.gulp-tsc-tmp*.ts'
}, function () {
console.log('Test');
});
See the documentation.
I was having this problem too, and solved it by removing "./" from the beginning of my paths:
gulp.task('watch:Feature', function() {
gulp.watch(['js/Feature/**/*.ts', '!js/Feature/.gulp-tsc-tmp*.ts'], function () { console.log("Test"); });
});
I'm using this Gulp Watch sample: https://github.com/floatdrop/gulp-watch/blob/master/docs/readme.md#starting-tasks-on-events.
var gulp = require('gulp');
var watch = require('gulp-watch');
var batch = require('gulp-batch');
gulp.task('build', function () { console.log('Working!'); });
gulp.task('watch', function () {
watch('**/*.js', batch(function () {
gulp.start('build');
}));
});
When I run it on my Windows 8 machine, it only runs the first time I change a file:
C:\test>gulp watch
[08:40:21] Using gulpfile C:\test\gulpfile.js
[08:40:21] Starting 'watch'...
[08:40:21] Finished 'watch' after 2.69 ms
[08:40:31] Starting 'build'...
Working!
[08:40:31] Finished 'build' after 261 µs
Next time nothing happens. Why?
For me it was adding a "return" to the task:
gulp.task('styles', function(){
return gulp.src('css/styles.css')
.pipe(autoprefixer())
.pipe(gulp.dest('build'));
});
If you read the documentation closely, you see the following phrase:
You can pass plain callback, that will be called on every event or wrap it in gulp-batch to run it once
So, that's basically the deal with gulp-batch. To constantly watch it, just remove the batch call:
gulp.task('build', function (done) {
console.log('Working!');
done();
});
gulp.task('watch', function () {
watch('app/*.js', function () {
gulp.start('build');
});
});
(and add the 'done' callback to build to let Gulp know when you're finished).
Btw... I'm not sure, but I think gulp-watch is meant to not only watch files, but also directly returning a vinyl object. So actually using the built-in gulp.watch should have the same effect:
gulp.task('watch', function () {
gulp.watch('app/**/*.js', ['build']);
});
This appears to be known issue
I had the same problem and used the same as ddprrt. The difference was using directory glob (wildcard) as apposed to absolute path.
I changed this:
gulp.task('watch', function() {
gulp.watch('sass/shortcutcss/*.scss', ['sass'])
});
to this:
gulp.task('watch', function() {
gulp.watch('sass/**/*.scss', ['sass'])
});
This problem made me crazy for a weekend. I tried all:
Add done()-Event
Rename/Touch/Clear target CSS
Be more specific with the filepaths
But the (reason for this problem and) the solution was so easy that I felt pathetic after that:
Just update your nodejs installation, mine was 0.12.x! No wonder that this doesn't worked.
After that the watch event works again. Sometimes it goes wrong again, too. But in this cases just save your file a second time and it get recognized. (I think foundation/gulp watch checks for changes to fast and while your file get replaced with the new uploaded one)
Long story:
For me it did not work for long time. All seems to be set right but run only once.
But suddenly I started with parcel js on another project and same thing happened with their builtn watch. So I looked for the answer and I found out that problem was with my Vim settings.
Answer what helped me is this one from #acobster https://stackoverflow.com/a/55435197/2686510
In short:
Update .vimrc by adding set backupcopy=yes
