Guides are taken from the source directory, and the result goes into the
|
|
output directory. Assets are stored under files, and copied to output/files as
|
|
part of the generation process.
|
|
|
|
You can generate HTML, Kindle or both formats using the `guides:generate` task.
|
|
|
|
All of these processes are handled via rake tasks, here's a full list of them:
|
|
|
|
#{%x[rake -T]}
|
|
Some arguments may be passed via environment variables:
|
|
|
|
RAILS_VERSION=tag
|
|
If guides are being generated for a specific Rails version set the Git tag
|
|
here, otherwise the current SHA1 is going to be used to generate edge guides.
|
|
|
|
ALL=1
|
|
Force generation of all guides.
|
|
|
|
ONLY=name
|
|
Useful if you want to generate only one or a set of guides.
|
|
|
|
Generate only association_basics.html:
|
|
ONLY=assoc
|
|
|
|
Separate many using commas:
|
|
ONLY=assoc,migrations
|
|
|
|
GUIDES_LANGUAGE
|
|
Use it when you want to generate translated guides in
|
|
source/<GUIDES_LANGUAGE> folder (such as source/es)
|
|
|
|
Examples:
|
|
$ rake guides:generate ALL=1 RAILS_VERSION=v5.1.0
|
|
$ rake guides:generate ONLY=migrations
|
|
$ rake guides:generate:kindle
|
|
$ rake guides:generate GUIDES_LANGUAGE=es
|
|
