[Question] How to load files as binary data other than the html file? #48

Closed 8176135 closed 5 years ago

Is there a way to load files like how the html file is loaded in the examples.

let mut frame = sciter::Window::new();
frame.load_html(html_vec, Some("some/path"));

But for other files like fonts or css files?

Think of a document viewer. If you load an HTML file, it would display it on window (and its associated resources, like images, fonts, or styles). If you loaded a CSS file, what would you expect to see? Its text?

I think, you want the following instead:

<html>
  <head>
    <style type="text/css">
      /* include styles */
      @import url(styles.css);

      /* include fonts */
      @font-face {
        font-family: 'FontAwesome';
        src: url(fontawesome-webfont.ttf);
        font-weight: normal;
        font-style: normal;
      }  
    </style>

    <script type="text/tiscript">
      /* include additional scripts */
      include "script.tis";

      debug "hello, world";
    </script>

So, if you have the following structure:

| `-- main.html
| `-- script.tis
| `-- styles.css

Then you could load everything with a single call:

// Sciter requires absolute paths when loading HTML.
let mut cwd = std::env::current_dir()?;
cwd.push("main.html");

frame.load_file(cwd.to_str()?);

Well, what I'm trying to do is include the source files (html css fonts tis...etc) within the binary rather than in a separate folder alongside it.

With the load_html function, I can use include_str! macro to include the html file and when distributing I can just send the standalone executable, my question is is there a way to do the same for the other files without in-lining everything.

Thanks.

I see. Use packaged resources: ZIP archives or Sciter archive with packfolder packer. Or you can implement your own data loading handler in extreme cases.

Basically, you will pack everything in a single archive file which can be included via include_bytes!.

P.S. Though I am not sure that ZIP archives can be kept in memory, perhaps, they can be loaded from file system only.

packfolder seems to be what I'm looking for, thanks!
