[SOLVED] LQ Option to Export a Thread to EPUB format to Read Later in Travel ?

It is more or less not that extremely complicated. I found yesterday.

1) First step is to wget without pictures the thread in print mode. You need an HTML file, since it is even nicer.

2) html2xhtml to make chapter.xhtml file.

html2xhtml thread.html > chapter.xhtml

3) copy the file to chapter.xhtml into OEBP directory. here the example: https://github.com/spartrekus/basic-epub-example

4) into bash, type:
makefile

5) Upload it onto your ftp favorite website, and download it from your Linux Ebook reader, read, rocking chair, drink coffee and relax at the sun.

Et Voila !

I don't mean to one-up you, but your post inspired me to create a simpler solution
It uses pandoc, so you may need to install it. Defaults out index.epub if you don't define output file.

# Usage: html2epub URL output.epub
html2epub() { url="$(echo "$(grep -oE '.*[0-9]{4,}' <<< "$1")"'-print/?pp=50')" && pandoc -f html -t epub3 -o "${2:-index.epub}" <(wget -q "$url" -O -); }

html2epub 'https://www.linuxquestions.org/questions/lq-suggestions-and-feedback-7/lq-option-to-export-a-thread-to-epub-format-to-read-later-in-travel-4175602548/' mybook.epub

Sometimes pandoc sends out this error message though, not sure why.

pandoc: Cannot decode byte '\x99': Data.Text.Internal.Encoding.Fusion.streamUtf8: Invalid UTF-8 stream

EDIT:

For the truly adventurous, this is my first usage of >() and will host the file using woof at http://lanaddr:8080 to be accessed (seems to fail more often though)

html2epub() { url="$(echo "$(grep -oE '.*[0-9]{4,}' <<< "$1")"'-print/?pp=50')" && pandoc -f html -t epub3 -o >(woof -) <(wget -q "$url" -O -); }

very good!!!

Pandoc is not reliable, unfortunately, and you can get several issues such as encoding. Likely, the best is to try to use C or C++, to make clean conversion, since the conversion is not complicated. It is a bad choice to use pandoc for making an epub, which is just a ZIP file.

My way is the following:
(1) You don't need pandoc.
(2) You need only GCC + ZIP installed, and nothing else to do a clean job of any types of HTML to beautifully made EPUB.

Not true Just right now fighting with ^L, ^B just to make an EPUB !!

ncpcln file.in file.cleaned

	    else
              m = fwrite( buffer, sizeof(char), 1,  fp2);
        }
        fclose(fp2);
        fclose(fp);
      }
}

this will allow to make a cleaned plain text file.

Then you can bring it into it in the <middle>

<?xml version="1.0" encoding="iso-8859-1"?>

<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title> New Section </title>
  </head>
  <body>
    <h1>
      doc using plaintext file
    </h1>


  <here it is the middle >

  </body>
</html>

It is not that easy to made an epub by hand

- Let's forget guys about EPUB. EPUB is not a good format for this aim.
- PDF with "reflow" option is not good either.

It makes no senses, since this EPUB is built on xhtml+xml.

Here's a list of major browser standards introduced roughly after Netscape 3 (when I started noticing browser devolution):

PNG HTML 4.01 CSS1 PHP JAVA DOM / DHTML XHTML CSS2 SVG

After studying the question on this website https://en.wikipedia.org/wiki/Compar...e-book_formats, it seems that open source free ebook format GNU is not available.
Probably the best is to make export to DOC since it is old, outdated, but however it is fairly readily stable on an ebook. Whatever encoding it works. When I have strange chars between 0x02 and 0x26, it hangs pretty well. Epub with too many pages are also not readily working.
