Recursive directories via command line

[jakemauer]

Hey Ivan,

First thank you so much for your work on this.

Is there a way to target multiple directories or recurse through directories and compress all images within?

Hi Jake,

Thank you, I am glad that my work it helpful )

For now there is no option to tell image_optim to find images in directory. Though you can pass all files (using globs or find) and non images will be ignored (directories will be also ignored, but you will get a warning).

I remember that I was thinking of adding recursive search but don't remember why I did not implement it. It should be simple to add, I'll try to do this soon.

Thanks Ivan,

I'm using image_optim find **/*.{png,jpg,jpeg,gif} for now and it seems to work. Any issues with this?

[toy]

Only now I've noticed that command seems wrong as image_optim find **/*.{png,jpg,jpeg,gif} will try to optimize file named find and whatever it can find by glob.

I've already added code for recursive searching for files, though I should add selecting only images and change how non images are handled inside, than there will be next release.

0.6.0 is out with recursive search for images.

How do you utilize the -r recursive option?

[toy]

@el3ment For example image_optim -r dir_a dir_b dir_c. It will scan those three directories for images that it can optimize and will run optimization process. With -r you can mix directory paths and file paths in one call.

[el3ment]

Thanks for the timely response! Just as a small caveat - in directories with lots of folders and files, image_optim -r */.{jpg,png} or image_optim -r ** will result in an "Argument List Too Long" shell error - do you know of a convenient way of avoiding this error?

[toy]

@el3ment In your case simple image_optim -r . should work as expected. In other cases you can use find with -exec like find . \( -name '*.jpg' -or -name '*.png' \) -exec image_optim {} +.

Hi all ,

Please i have you probleme when typing : image_optim *.{jpg,png,gif,svg} on my shell

i got this :

WARN: advpng 1.15 at /usr/bin/advpng (< 1.17) does not use zopfli
WARN: gifsicle 1.60 at /usr/bin/gifsicle (< 1.85) does not support removing extension blocks
Bin resolving errors:
pngout worker: pngout not found; please provide proper binary or disable this worker (--no-pngout argument or :pngout => false through options)
pngquant worker: didn't get version of pngquant ? at /usr/local/bin/pngquant; please provide proper binary or disable this worker (--no-pngquant argument or :pngquant => false through options)

Can you help me please ?

Thank you

[toy]

@bloodymind Simplest way to get up-to-date versions of nearly all binaries is by installing image_optim_pack gem, the only requirement is operation system — linux or osx.
If you are using it for a project using bundler, you may want to add it to Gemfile.
Also pngout is not yet packed due to license, so you need to download it manually and put it somewhere on path.

Otherwise please check binaries installation section in readme.

Hi @toy ,

That's working now 👍

Thank you.
