Indexing#

An index lets you efficiently look up any topic. In the age of full-text search, you are right to wonder what the point of indexes are. They could be seen as companion of cheatsheet: instead of searching and hoping you find the hright place, you can index the actual locations to which one would refer.

As you might expect, there is nothing special to in sphinx-lesson about indexing: see the Sphinx documentation on index.

Basic concepts#

Headings are the terms which can be looked up in the index. When choosing headings, consider:

  • What is useful to a reader to locate

  • How would a reader look it up? For example, commit or committing is useful, but how to commit is not. Phrase it with the most important terms first (big-endian)

  • And index can have sub-entries. For example, under the entry git, there can be subentries for each git command, such as commit.

Syntax#

See also

The Sphinx documentation on index.

The index directive and role are the main ways to add index entries. The semicolon (;) character separates entries and subentries.

Index a block with the directive, with ReST:

.. index:: commit; amend

Or ReST, multiple:

.. index::
   commit
   commit; message
   pair: commit; amend

MyST:

```{index} commit; amend
```

```{index}
commit
commit; mesage
pair: commit; amend
```

Or index a single term with the role:

This sentence has an index entry for :index:`commit`.  If you want the
indexed term to be different, standard syntax applies such as
:index:`loop variables <pair: commit; amend>`.

MyST:

Simple entry: {index}`commit`
Pair entry: {index}`loop variables <pair: commit; amend>`

There are different styles:

  • TERM, same as below

  • single: TERM (the default): create just a single entry

  • pair: TERM; TERM: create entries for x; y and y; x

  • see: TOPIC; OTHER: creates a “see other” entry for “topic”.

  • seealso: TOPIC; OTHER: creates a “seealso” entry, like above

Glossaries#

If you make a glossary using the glossary directive, the terms automatically get added to the index
