RE: [docbook-apps] Epub3

>"zip" is the Info-zip program to create and manipulate zip files.

I know that (and I already knew it), but ....

note to the maintainers of the documentation - please state it explicitly; as I indicated I got the "'zip' is not recognized as an internal or external command, operable program or batch file." message as it isn't a standard operating system file. Someone reading this who isn't a developer may not know what's meant.

Also please add a note to the effect that its folder *must* be in your path. Just adding a symbol pointing to zip.exe is not sufficient. Presumably there is something else important in the folder.

I've been trying to get 7-zip to do the job.

Firstly it needs telling to do "zip" format, which can be done using -tzip.

However, it seems to be insisting on putting everything in the file in alphabetical order, which isn't accepted by epubcheck.

So for the moment the answer seems to be that 7-zip can't build epubs. Unless someone can tell me how to sort out the ordering.

Unhelpfully,

Richard.

Zip is just a compression format. "zip" is the Info-zip program to create and manipulate zip files. 7-zip can create zip files so you just need to adapt the CLI args to add the files you need to a zip archive with an extension of '.epub'

I decided to try building an epub from my DocBook document, using epub3 .....
Following the instructions in the README.

Step 1. XSL (epub3/chunk.xsl) to generate Xhtml and other files.
That seems to work fine.

Step 2. Copy in any image files.
I wrote some XSL to scan package.opf and generate a batch file to do the copy.
I don't think XSL (or Saxon) has a built-in ability to copy files, so I build a batch file then run it.

Step 3. Zip it.
Ok, so I do the command as in the README -
zip -r -X mybook.epub mimetype META-INF OEBPS

And I get -
'zip' is not recognized as an internal or external command, operable program or batch file.

So - firstly, if referring to a program that isn't part of the operating system, please explain exactly what is meant.

Anyway, I thought I recognized the syntax as Info-Zip's zip (I normally use 7-zip) so I set about getting a copy.
Ok, the download is FTP, which I haven't used for ages. So install Filezilla and try and download an info-zip exe.
Eventually find an exe, from zip323xn. Add its folder to my Path.

Then run it ....
zip -r -X mybook.epub mimetype META-INF OEBPS

And now I get -
zip warning: multiple disk information ignored
<path-to>/Info-Zip/zip232xn/zip.exe: found a preamble of 20832 bytes
zip warning: name not matched: mybook.epub
zip I/O error: Permission denied
zip error: Could not create output file (<path-to>//Info-Zip/zip232xn/zip.exe)

Ok, so can someone tell me how to actually get this to work ?

And ......
Can 7-zip be used for this, if Info-zip's zip is going to give problems ?
I think I've seen somewhere that "mimetype" should be in the archive but not compressed. Is this so ?
If so how do we get it not to compress certain files ?

Frustratedly,
Richard.
