Tips and tricks
Using Crowbook with Emacs' markdown mode
If you use Emacs as a text editor, there is a nice Markdown mode to edit Markdown files.
It is possible to use Crowbook for HTML previewing in this mode, which requires only minimal configuration and tweaking:
(custom-set-variables
'(markdown-command "crowbook - -qs --to html --output -"))
You can then use markdown-preview
(or C-c C-c p
) to run
Crowbook on this file and preview it in your browser, or run
markdown-live-preview-mode
to see a live preview (updated each time
you save you file) in Emacs' integrated browser.
Some explanations if it looks a bit cryptic to you
We set markdown-command
to crowbook
, the reason for this is a bit
obvious. The arguments we give to crowbook might be a bit less
obvious:
- the fist argument,
-
, is actually the book file: it tellscrowbook
to read it from standard input. -qs
or--quiet --single
tells Crowbook that is a a standalone markdown file, and not a book configuration file, and to be a bit quiet on error/info messages;--to html
specifies that HTML must be generated;--output -
tells Crowbook to display the result on the stdout, even if you setoutput.html
tosome_file.html
.
Embedding fonts in an EPUB file
In order to embed fonts in an EPUB file, you'll first have to edit the stylesheet, which you can first obtain with:
$ crowbook --print-template epub.css > my_epub_stylesheet.css
You'll need to use the @font-face
attribute:
@font-face {
font-family: MyFont;
src: url(data/my_font.ttf);
}
Then you can add my_font.ttf
to the files that need to be added to
the EPUB zip file:
title: My Book
author: Me
cover: cover.png
output.epub: book.epub
resources.files: my_font.ttf
(Note that you'll have to repeat the process for the different
font-weight
and font-style
variants of your font if you want it to
display correctly when there is some text in bold, italics, or both.)
