Thank you, @schroef , the update works great for me 💯 @fuzenco appreciate I wasn't alone in this, hope that the script works for you too

@jjaybyrd Welcome. We’re back to using this great script.

@jjaybyrd @fuzenco
Perhaps i could add Gradients as well, but thats is more complicated and im not sure how we should tackle that. I mean a gradient can be very complicated and can have many colors. Not see i see value in adding it.

I think my ideal feature for this script would be to export color groups (as in folders in the color palette) as separated groups in the CSV file. Now that would be awesome.

@schroef It's an interesting idea, but I'm considering its usefulness for graphic design purposes 🤔 Illustrator's classification and handling of gradients is in my opinion pretty clunky. There isn't really a super short-handed way communicate gradient information (other than maybe sharing swatches). I typically have to give specs for combined colors and percentages for placement. If anybody else has a better way of doing that though, would be super interested to hear

@schroef ill test it out

@jjaybyrd @fuzenco

Okay, i got gradients also working now. So it shows the name and then below that all the gradient color stops
Not sure you guys are interested in that

Im not sure i follow? Could you explain that different. Im not sure what is wrong with current method of sharing gradient?

@schroef sorry i think i was just venting about what i perceive as an illustrator problem in that you can communicate color stops but not easily their placement on the color slider. Your added approach above actually really helps me with a current project I'm working on (i was having to manually select gradient color stops), honestly thank you for all your great work 😃

@jjaybyrd
Well editing color stops is not that difficult, especially in the last couple of illustratie versions. It's always best to to use global colors, because if you would edit those color, all your gradients in the document will be adjusted. It's always better to use global colors for ease of use.

I'll update the current version tomorrow with this new edit

Guys, I’ve been designing for close to 30 years. One simple way of creating gradients and saving them as a color palette is to create a blend.

1. Create two squares (or whatever) with the first and end color you want to use
2. Select them and choose Object > Blend > Options
3. Enter Specified Steps (in this case 8)
4. Go back and choose Object > Blend > Make
5. The gradient gets created and then…
6. Choose Object > Blend > Expand
7. Then distributing the items via Horizontal Distribution Evenly

I usually then just select the entire row and save to my palette. It's a quick and easy way to create gradients but more importantly to have the color stops at your disposal for using as needed.

Sorry if this derails this conversation but @schroef addition of gradients is cool in my opinion. I would just need to test what he's done.

In my case, if I used the blend method AND there were a way to group palette folders together in the CSV (maybe a blank line between groups), that would be a great addition to this script.

@jjaybyrd @fuzenco

okay i added updated version, this one can also do gradient colors
I will add "Gradient Color", so user know where it starts, then i add "ColorStop X" for each colorstop. I first had the color value as name, but that made the colorstops below the gradient color much longer in name. It works in both RGB and CMYK documents

This is masterful @schroef. I will test it out this afternoon. Thank you 👍

p palette folders together in the CS

Yes i know that method, but one would only use that if they needs to color stops. Perhaps that is usefull GUI designers which want tints or inbetween colors of a gradient. Downside it adds a lot colors. PS i also have a script which can turn those colors into a real gradient. If i recall correct

PS i dont see how i could add colorgroups clearly in the CSV without changing the formatting to much. Basically adding the gradient is already changing that.
If i recall correct, the colorgroups are not exposed to script. ExtendScript doesnt know if a color is inside a color group

@schroef this is great, much clearer. it's been fantastic to see this progress after my silly little comment lol, looking forward to testing it out
@fuzenco thanks for the helpful tip, it seems like this might only work for evenly distributed gradients though? correct me if I'm wrong

@schroef . Tested it. Gradient export works perfect. However…

I do see a bug in the script, though. After creating my gradients and properly exporting, if I add additional standard swatches (in my case 2 colors in a color group/folder), those two new colors do not get exported when the same file name is used for the CSV. In my case, I had to duplicate the file and rename it. Running the script did include the two new swatches this time around.

Here’s the file I used: http://fuzen.co/dropbox/test2.ai.zip

@jjaybyrd yes, only for evenly distributed gradients. But prior to this script, getting color stop values was a manual process for me.

Understood. You’ve done a masterful job.

That script to convert colors to a gradient would be cool. Is it somewhere I can download?

@fuzenco
You mean it doesn't overwrite the existing CSV file?. I'll test that file
I don't have issues with that on my windows system

@fuzenco
Actually swatchgroups are exposed. I see what I can do about that. I would need to check if can test if a swath or spot is a child of a search group, than it would be possible
..

I did found it, it was made by someone else. It only does CMYK now. I'll need to update it so it will do all kinds of document color modes

I just tested your file and it works just fine with v002. I opened your test doc and add a new swatchgroup and added 3 extra colors. I had the csv export from earlier open in Visual Studio Code and after a new export, those 3 colors where added.

You do have v002 right?

I do but it must have been an intermittent bug. 3x I tried to overwrite that initial file. The new file was saved (which overwrote the test2 file), but the new colors were not being added. However, today everything seems to be working fine although I had 002 all along. So disregard this report and if it pops up again, I’ll notify you. Thanks.
