When running npm run build -- ttf::iosevka-ss09 the build process stucks at 66% (74 tasks pending) with all 4 CPU cores run at 100% for hours.

Looks like an endless loop being caused by the width = 600 parameter - the only one changed.

I've built several versions with a width of 600 before. The last was 3.0.0-rc.8. It also took some time but finally got through it.

I can confirm this with git commit eea51f6 the install process is stopped at extendedheavyoblique when running with npm run build -- ttf::<MYBUILD> ...

[be5invis]

The modification “weight = 600” is NOT tested, and may frequently create broken shape/hangs.

[be5invis]

weight = 600 combined with "Extended" will create a variant that having width around 700. Is it intensional?
Considering you have already modified the width, you can simply disable extended variants like this:

[buildPlans.<your build name>.normal]
shape = 5
menu  = 5
css   = "normal"

This will remove extended subfamilies and leave "normal" subfamilies only.

@wimstefan I cannnot repro this with unmodified parameters.toml. I build dev branch every day and nothing strange happened.
Could you please double check that the your parameters.toml is indeed unchanged (i.e., identical to the original repository's)?

[wimstefan]

@be5invis there's definitely no change in the parameters.toml
I have a couple of small changes to the slant in a private.toml like this

[artesanal]
slantAngle = 2
[artesanal.multiplies]
sb = 0.88
width = 0.88

And yes I'm building my fonts also after every commit without a problem ...

[be5invis]

I can confirm this with git commit eea51f6

@wimstefan What build are you testing? @deathaxe's build or yours?

[be5invis]

I've submitted a patch so it should fix this break. Closed.

[wimstefan]

I'm testing my own configuration as shown above ... since you've committed a couple of things to the dev branch I've reached commit 0213055 in the meantime. But it still hangs on the same spot despite adding your tip above to my build configuration:

[buildPlans.<your build name>.normal]
shape = 5
menu  = 5
css   = "normal"

I've jumped on this issue since I was presuming it is the same sort of issue I'm experiencing as well. I'm sorry if I disturbed the original issue report ...

[be5invis]

@wimstefan Are you adding slope even for regular? This is definently out of our support scope...You can consider remove the heavy weight if you do not need it.

[wimstefan]

@wimstefan Are you adding slope even for regular? This is definently out of our support scope...You can consider remove the heavy weight if you do not need it.

It's a very slight slant only and I'm using it already more than 2 months in this private.toml - before I was using the same values in parameters.toml without a problem ...
I'm just wondering why it worked until today?

I need the different weights btw since I'm using Iosevka nowadays for all my application, wm and GUI fonts as well ;-)

[wimstefan]

OK now it's getting interesting ...

I've checked out the latest commit, removed the slant.Angle from my private.toml and deleted all build and dist directories ... but the build process still hangs at the same spot ?!?

What else can I do to get more information what's going wrong?

[be5invis]

@wimstefan You also shrink the characters width which may also cause problem.
I may add tracing later but for now removing Heavy (or reducing its shape weight?) should help.

[be5invis]

@wimstefan Actually, it is hanging when building the Pound Sterling (£) symbol, the upper hook is too tight so the geometry engine cannot handle it. A patch has been submitted.
And, since you reduced the characters' width, I strongly suggest you to also reduce the stroke width to avoid broken shapes (I saw a lot in Heavy).

[wimstefan]

wow thanks for finding the reason for this issue! That was certainly not an easy one. Hats off Sir!

I can confirm that removing the Heavy from private-build-plans.toml helped initially to finish the building process and after pulling the latest commit 132c917 it was even possible again to build the Heavy variants. Thanks a lot for that!

I try to follow your suggestion but am not sure how to achieve that? I'm not sure which value I should use which is corresponding to the sb and width values I've already configured. I only find stroke values with big number in shapeWeight.blend.xxx settings ...

[be5invis]

@wimstefan Just change the shape weight in your build plan.
The stroke width will be inferred from them.

[buildPlans.iosevka-artesanal-curly.weights.regular]
shape = 400 # May Reduce this
menu  = 400
css   = 400
[buildPlans.iosevka-artesanal-curly.weights.book]

[wimstefan]

That's good to know. Unfortunately I'm not clever enough to understand the logic behind the building of this marvelous font :-/ Thank you so much for helping me!!!
I'll give it a try immediately and report back ...

[deathaxe]

The modification “weight = 600” is NOT tested, and may frequently create broken shape/hangs.

I modified width not weight. The normal font is quite too narrow, I think. That's the only issue I want to fix for this otherwise incredible font.

I use the customized (width = 600) iosevka SS09 Light Extended in Sublime Text.

Don't find it too wide.

Haven't learned too much about font editing so don't have any idea how to build my own build plan or which values needed to configure to do certain customizaiton. Was happy about being able to make the font a little wider at all.

[be5invis]

@deathaxe Extended subfamily will further multiply the width by 1.152 so your final width will become 0.6912em. Maybe I need to introduce a new family (wd-9, Ultra Extended)?

Anyway...

1. The hang is fixed in last build.
2. Changing parameters.toml is strongly discouraged. Use private-build-plans.toml for customization.

[deathaxe]

Thanks, very much.

Tried to adjust it to match the width of Source Code Pro, which is quite wide as well.
The default extended variant is 0.576em? Maybe 0.7em is indeed too wide for general use.

Having some safe options to increase the width would be appreciated. Not sure if an "Ultra Extended" needs to be built by default or just supported for private build plans. Maybe there are just too many aspects of taste to decide it atm.

The wd-# are the recommended/only way to define width in private build plans as well (instead of a width value)?

Just not sure what a good multiplier would look like, maybe 1.2 (0.6em), 1.25 (0.625em) or even 1.3 (0.65em)?

Looks like I definitely need to dig a bit deeper into all that stuff to get the best out of the font using private-build-plans. ;-)

[deathaxe]

Built a variant with a (hacked ;-) ) width value of 550 which results in 0.63em for extended font variants. From what I can see, a wd-9 with 1.25 (0.625em) might be very much ok.
