Context: https://github.com/timjs/elm-collage/issues/36 Summary: I’m using elm-collage to display some text. This package used to make a native synchronous call to measure the text size . Of course, that isn’t possible anymore. So, they’ve “reverted to a very simplistic calculation using the font si…

[image] hossameldeen: As a package user (not author), how would you go around this issue? Do you have any solution in mind? For computing the text width, there is this package from @folkertdev : [image] Experiences using elm/bytes for decoding font files Over the past weeks I’ve been writi…

Yes. The package a work in progress, but should make this possible. A problem if you want it to be synchronous is that currently, I still need to load the font file to parse it and extract the size of each character. The idea is to have some web-app somewhere that you can give a font and it will sp…

[image] folkertdev: A problem if you want it to be synchronous is that currently, I still need to load the font file to parse it and extract the size of each character. Good point, I did not give this much thought before. If the font file is only loaded at runtime, the overall process would s…

I ended up using ports for this. I have the advantage of using only static strings that can be measured once (although the app also scales). I also use CSS animation to hide the initial state where things are not yet correctly aligned. Not a real solution, but thought what others are doing might be…

@folkertdev Thank you, will keep an eye on the package to see how the experience would turn out! @wondible That’s a good idea! Actually, my use-case is indeed static! Does your code happen to be open-source in order for me to not reinvent the wheel? (P.S: Thank you Viir for pointing out to elm-cf…

If your use-case is static, maybe you can just store the widths of the characters in a mapping function and do something like a string |> toCharlist |> List.map charLength |> List.sum?

@wondible Thank you; that’s beyond awesome! … I’m also thinking about precomputing in Javascript the widths of all the strings used in my application and then giving everything in as flags , in order to not have any asynchronous code in Elm. However, haven’t actually tried it, so don’t know if that …

In case you are interested, I have a ports solution for this: https://package.elm-lang.org/packages/the-sett/svg-text-fonts/latest/
