I just discovered that vim can open and edit files inside a zip file automatically, which of course means it can do the same for epub. Which is awesome :)

Add the following to your .vimrc:


au BufReadCmd *.epub call zip#Browse(expand("<amatch>"))

Thank you very much. vim is my text editor at PC, so it's very useful for me.

Great tip, thank you! :)

Got to love the vim... I use gtk-vim a lot here, very nice spreading it all over large panels :)

Does it rezip correctly so the epub validates? I know 7zip doesn't.

I just tried editing a valid ePUB (deleted some content from XHTML and CSS files), and it remains valid. I don't know which "options" it uses to rezip the files, though.

On Unix it uses

zip -u

which will only affect the changed files.

Great tip, thanks Kovid!

Thank you very much, this really is handy!
