This is exciting. Very exciting. For the sake of this community, please be sober enough tomorrow Happy new year to you, your help has been very precious and lots of our projects were inspired by your templates & ideas. Thank you
Haha thanks for the reference @Paul_Danyliuk. Maybe one day.
I remember you were quitting Coda because of pricing — didn’t the update change your mind?
The way you hacked stuff together in those gradient generators and music players — if you put that kind of creativity and dedication to the SVG capability, it would be da bomb
I didn’t so much “quit” Coda as I decided on a different tool for now to accommodate different priorities. I like Coda, and will come back to it.
As for the “gradient generators and music players,” I must admit that you are thinking of someone else. Time to update the post with the real hero!
O shi~ you’re right! I remembered you from Omnicodoro (thought of all the task nesting you did) and assumed that was you too.
Of course I meant @Phil_Hamilton-Schmidt!
Best of luck though!
OK @Jay_Lefebvre and the others, here you go:
@Paul_Danyliuk , this is amazing! Above and beyond. Congrats! This is gonna take a while to process. But can’t wait to work with these capabilities.
The pricing announcement was an emotional time for everyone. Who was I kidding! I could never leave coda. I just think about my docs a little differently now to keep em at the free tier.
@Phil_Hamilton-Schmidt I messaged you on facebook
@Paul_Danyliuk wow, that is a stunning idea! but not only that, the mindmap is already a full working super useful proof. genius!
Sorry I’m new to coda, I click on Open in coda but I can just see code, no actual image.
Hey! It’s on the last column, you’ll see it if you scroll to the right.
This is more of a pro trick though. You’ll benefit more if you get comfortable with the “out of the box” stuff first I think Welcome to Coda, and we’re here to help.
Thanks, I watch a few tut it’s all about spreadsheet like features, so I was not very interested, until I see this svg. But what kind of doc or template to use then to be able to create SVG in coda ?
Well, here’s one working example / proof of concept:
Here I’m using the table of tasks to calculate the X/Y coordinates of each node, then generating SVG for individual nodes and connector lines to parents (as simple as center X/Y of one node to center X/Y of another), and finally combining that all together into something that can be fed to
Image(). I had to figure out the algorithm to calculate node position myself (and it’s a pretty naive one, although it gives good-enough results). You can do something similar for your needs. This said, you either need to know how to compose SVG code, or use an editor and then strip out all the bloat that editors usually put inside exported SVG.
To put shortly, I’m simply leveraging standard browser functionality.
Coda translates function
<img src="url" … />. Well, it removes whitespaces, but nothing beyond that.
Browsers support Data URI — i.e. capability where instead of resource link (URL) you’re providing the data encoded right there. You may have encountered this with Base64 mostly.
So the task was ultimately to compose data URI to feed to the Image tag that would be rendered as a valid image. SVG is a text format (i.e. easy to compose by simply concatenating strings and filling in parameters with
Format(), so it was an obvious first choice.
Since Coda strips out spaces from the data URI and SVG needs them, I went with URI encoded format. Since Coda’s own
EncodeForUrl()was far too eager and encoded more than it should have (and the output wasn’t rendering at all), I kinda implemented my own.
In the very end, I’m composing SVG elements out of data rows, concatenating them together, URI encoding, prepending with
data:image/svg+xml;, and feeding to Image()
Thanks a lot for all these detailed explanations, I have to learn coda.io more thorougly to understand them I guess
Just found one interesting place where SVG works but multiple
Rectangle()s won’t — in detail layouts:
Here’s how the same progress bar looked when built with rectangles:
@Paul_Danyliuk good find, this looks so good! What does the code look like for a progress bar like this? Sorry, definitely not an expert in SVG
Edit: This also opens the door to gradients and better looking progress bars
Is there a site where you can generate SVG code? Thanks a lot
Edit 2: Found a few ones but would still love to know how you did it ahah
Gradients — totally possible. This exact layout is actually possible.
Online editors — not sure. But there’s a range of standalone vector drawing applications, from free (e.g. Inkscape) to paid (e.g. Affinity Designer, Adobe Illustrator) that export SVG. One downside is that they usually export a lot of extra metadata within the files. E.g. see the “organization chart” example in the doc in my original post — I simply copied the first copyright-free chart from Wikipedia I found, and perhaps 90% of its SVG code is redundant garbage that could easily not be there.
It is actually very simple to compose SVG by hand and include only the essentials. There are lots of tutorials. One of the knowledge sources on web technologies that I personally trust is MDN:
Here’s how I did that particular one. I already fed urlencoded SVG (prepared through my doc) to avoid unnecessary calculations, since it was simply about filling in one width value:
It’s just two
<rect />s in an
<svg />, no groups even.
I struggled with this in the Meeting Agenda template. The detail view wants to crop and size images to fit for some of the layout options and forces rectangles to squares. That’s why all the timer stuff is outside the detail view layout and in the canvas.
I might have to dig in and give this strategy a try.
