I could tell my client that but it's not true, and I wouldn't believe myself (I'm the client) anyway.

I've got unicode, i'm working on the typesetting. It's not that the device isn't capable - I think I've written enough of the code to prove that the ESP32 can do it. It's just that I don't know the behaviors of all of it - not that I'm trying to implement all of it - just enough to show most epubs mostly correctly.

You appaer to be in agreement with this statement of mine:

Quote:
Sure, you can get part of the way there on an atmega platform

So, yeah, that's completely true and factual - you can definitely get part of the way there! I'm guessing that the easiest bits can be done (inter-word spacing and hyphenation at syllable boundaries), but anything else you add in is going to result in a ragged right-edge.

If you are okay with a ragged right edge, then it all becomes doable on an ESP32 (that's like what, 80KB RAM?)

Adding, you didn't mention an atmega before so I'm not sure what you're quoting. In any case I didn't agree or disagree with that statement because you didn't make it.

This is what I responding to:

Maybe you should tell your client that the project they contracted you for is not completely realisable on their choice of hardware.

I'm quoting this post over here, which as you can see contains the sentence you missed:

Seems you're in agreement with that too, since you say:

That's what "not completely realisable" means.

First of all, you never mentioned the atmega in that post. I just looked at the link you gave me. I didn't miss a sentence. What was being discussed was the Arduino framework. It is only incidently related to an atmega in that an atmega will run it. It's not the only thing that does.

I bolded the relevant bits. You forgot the operative part. I was never contracted to build a 100% to spec e-reader.

Okay, what do you see as the second sentence in

The operative part being that you don't do this for money? It's damn funny then that you lecture some who does get paid for embedded stuff you are trying to learn Smile | :)

Anyway, back to the topic, you bolded the part where I said it's not compeletely realisable, and then you said you can do most of it, mostly.

Sounds like you agree but can't bring yourself to admit it. No as much as I like to see people whine that "I can't see the word atmega in a paragraph of two sentences" when given a direct link, I cannot entertain your self-humiliation much longer - as a professional I have paying clients to attend to. You'd do the same once you start getting paid for your "work".

I like that you think I'm trying to learn. I get paid to write embedded. I'm done with you. I have no patience for hubris.

Honey, ascenders and descenders are letters like 't', 'l', 'h' that ascend above a standard 'a' type character and descenders are 'p', 'q', 'y' that descend below a standard 'a' type character.

Oh I thought it was going to be something weird.

Yeah my stuff does that. It's basic truetype. you couldn't render fonts without it.

There is a pre baked library that covers many of these problems:
http://site.icu-project.org/

Do not underestimate the weedy-ness of wrapping text. Check out some of the South Asian scripts. Thai, for example, has no spaces.

Another strategy would be to scroll the too-long word. Think 1980's 16 character LED and LCD displays.

Fixed width fonts, know how many across, break there.
Is that an option?

I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.

honey the codewitch28-Jul-21 11:10

Not really. The whole thing is open type/true type and using digital typesetting. Worse, there are default fonts but they can be overridden by the EPUB via CSS.

And really the problem is knowing where I should break the word. I could do it right in the middle but that seems less than good.

As you are already neck-deep into CSS you should learn from it...

word-break: break-all;
To prevent overflow, word breaks should be inserted between any two characters (excluding Chinese/Japanese/Korean text).

What about hyphenating at random places Smile | :)

? How often do you need it ?

I'm not sure. It depends on the size of the screen that's connected to the e-reader I'm making. It can use any size screen, though in the end I'll be settling on a 600x800 epaper display

The browser rendering engine already has good support for splitting words.

I put "hypens: auto;" into my CSS and I am quite pleased with the result.

[edit]: My css is as follows (lookup the hyphenate styles for what they do)

CSS

body {
   font-family:         'Computer Modern Serif';
   margin:              40px auto;
   max-width:           640px;
   line-height:         1.6;
   font-size:           16px;
   padding:             0 10px;
   hyphens:             auto;
   hyphenate-limit-lines: 2;
   hyphenate-limit-chars: 6 3 2;
   text-indent:         30px;
}

Wouldn't that be great if I didn't have to implement my own web browser which is the whole point of this?

Well, your initial message didn't specify that as a point and my crystal ball isn't working today Smile | :)

But, isn't it great that I gave you a really nice introduction into the complexities of your problem over here:

I also didn't say I was using a web browser. It's weird that you would assume I was. C# is the most commonly used language at CP, not HTML and CSS.

Totally - since CSS engines are my bread and butter...
not really, I just thought EPUB displays content using something that is capable of CSS...

Yes, it does. I wish it didn't. I'm making an epub reader on a device that can't even run a basic web browser.
