This is the source for the Solr Reference Guide.
Raw content is stored in Asciidoc (`.adoc`) formatted files in the `src/` directory.
== Prerequisites for Building
These files are processed with AsciiDoctor in 2 different ways:
* HTML version, using Jekyll:
** `Ruby` (v2.3 or higher)
** The following gems must be installed:
*** `jekyll`: v3.5, not v4.x.
Use `gem install jekyll --force --version 3.5.0` to force install of v3.5.0.
*** `jekyll-asciidoc`: v2.1 or higher; latest version (3.0.0) is fine.
Use `gem install jekyll-asciidoc` to install.
*** `slim`: v3.0 or higher; latest version (4.0.1) is fine.
Use `gem install slim` to install.
*** `tilt`: v1.0 or higher; latest version (2.0.10) is fine.
Use `gem install tilt` to install.
*** `concurrent-ruby`: v1.0 or higher; latest version (1.1.5) is fine.
Use `gem install concurrent-ruby` to install.
== Building the Guide
For details on building the ref guide, see `ant -p`.
There are currently four available targets:
* `ant default`: builds the HTML versions of the Solr Ref Guide.
* `ant build-site`: also builds the HTML version.
* `ant clean`: removes the `../build/solr-ref-guide` directory.
The output of all builds will be located in `../build/solr-ref-guide`.
== Key Directories
Key directories to be aware of:
* `src` - where all human edited `*.adoc` files related to the Guide live, as well as various configuration, theme, and template files.
* `tools` - custom Java code for parsing metadata in our `src/*.adoc` files to produce some `_data/` files for site navigation purposes.
* `../build/solr-ref-guide/content` - a copy of the `src` dir generated by ant where:
** `*.template` files are processed to replace ant properties with their runtime values
** some `../build/solr-ref-guide/content/_data` files are generated by our java tools based header attributes from each of the `*.adoc` files
* `../build/solr-ref-guide/html-site` - HTML generated version of the ref guide
See the additional documentation in `src/metadocs` for more information about how to edit files, build for releases, or modifying any Jekyll templates.
