Compressing several files

[evanworley]

How can this be used to recursively compress all files in a directory?

For example, I want to generate compressed versions of all my assets along side their uncompressed version.

Thanks,
Evan

This should be what you're looking for: http://gruntjs.com/configuring-tasks#building-the-files-object-dynamically

Hi Tkellen,

Thanks for the reply. I'm familiar with building the file object dynamically, but when I do it in the way that I am familiar with, I get an error that no archive is specified. In case I wasn't clear, I am looking to individually compresses all files in a given directory (so for each foo.txt there will be a foo.txt.gz next to it). This is pre-compression to use with nginx gzip_static feature.

Can you please help me understand what configuration will achieve this? Right now I have the following configuration and it does not work.

compress:
  dist:
    expand: true
    cwd: 'dist/'
    src: ['**/*.js', "**/*.css", "**/*.html"]
    dest: 'dist'
    ext: '.gz'

Thanks!
Evan

Mode auto-detection is handled by the archive option, which doesn't apply to your style of compression.

Please try:

compress:
  dist:
    expand: true
    cwd: 'dist/'
    src: ['**/*.js', "**/*.css", "**/*.html"]
    dest: 'dist'
    ext: '.gz'
  options:
    mode: 'gzip'

I tried that configuration, and I got the following error message

Running "compress:dist" (compress) task
Warning: Unable to compress; no valid archive file was specified. Use --force to continue.

You're right. The gzip mode for this task is totally borked. I'll take a look at fixing it soon.

@evanworley This should be fixed now on v0.4.2. Thanks!

[evanworley]

Thanks for the quick fix. It works for the happy path case, but not when you have empty files. Please see my comment in c1c21e5

Fixed and published as v0.4.3. Thanks again!
