# pycancensus Documentation
2+
3+
This directory contains the documentation system for pycancensus, built with Sphinx and featuring:
4+
5+
- **Sphinx-Gallery**: Executable Python examples with beautiful thumbnails
6+
- **MyST-NB**: Markdown tutorials that execute as notebooks
7+
- **Autosummary**: Auto-generated API documentation
8+
- **Professional Theming**: Read the Docs theme with copy buttons
9+
10+
## Building Documentation
11+
12+
### Prerequisites
13+
14+
Install documentation dependencies:
15+
16+
```bash
17+
pip install -e .[docs]
18+
```
19+
20+
### Build Commands
21+
22+
```bash
23+
# Build HTML documentation
24+
cd docs
25+
make html
26+
27+
# Clean and rebuild
28+
make clean-all && make html
29+
30+
# Live rebuilding during development
31+
make livehtml # Requires sphinx-autobuild
32+
```
33+
34+
The built documentation will be in `docs/_build/html/`.
35+
36+

54+
## Adding New Content
55+
56+
### Adding a New Tutorial
57+
58+
1. Create a new `.md` file in `docs/tutorials/`
59+
2. Use MyST-NB format with executable code cells:
60+
61+
```markdown
62+
---
63+
jupytext:
64+
text_representation:
65+
extension: .md
66+
format_name: myst
67+
kernelspec:
68+
display_name: Python 3
69+
language: python
70+
name: python3
71+
---
72+
73+
# Your Tutorial Title
74+
75+
Tutorial introduction text.
76+
77+
``{code-cell} python
78+
import pycancensus as pc
79+
print("Your code here")
80+
``
81+
```
82+
83+
3. Add the tutorial to `docs/tutorials/index.rst`
84+
85+
### Adding a New Example
86+
87+
1. Create a new Python file in `docs/examples/` with filename starting with `plot_`
88+
2. Use Sphinx-Gallery format with docstring introduction:
89+
90+
```python
91+
"""
92+
Example Title
93+
=============
94+
95+
Detailed description of what this example demonstrates.
96+
"""
97+
98+
# %%
99+
# Section Header
100+
# --------------
101+
#
102+
# Explanation of this section.
103+
104+
import pycancensus as pc
105+
# Your code here
106+
107+
# %%
108+
# Another Section
109+
# ---------------
110+
#
111+
# More explanation and code.
112+
113+
print("Examples are automatically executed!")
114+
```
115+
116+
3. Examples are automatically included in the gallery
117+
118+
### Adding API Documentation
119+
120+
API documentation is automatically generated from docstrings. To add a new function:
121+
122+
1. Ensure the function is exported in `pycancensus/__init__.py`
123+
2. Add it to the appropriate section in `docs/api/index.rst`:
124+
125+
```rst
126+
New Section
127+
-----------
128+
129+
.. autosummary::
130+
:toctree: generated/
131+
132+
your_new_function
133+
```
134+
135+
## Documentation Standards
136+
137+
### Code Examples
138+
139+
- **Always include working examples** in docstrings and tutorials
140+
- **Handle API key requirements** gracefully (show setup but don't require real keys)
141+
- **Use realistic but sample data** when possible
142+
- **Add error handling** to show users what can go wrong
143+
144+
### Writing Style
145+
146+
- **Be concise but complete** - explain what users need to know
147+
- **Use active voice** and clear instructions
148+
- **Include "why" not just "how"** - explain the purpose
149+
- **Cross-reference** related functions and tutorials
150+
151+
### Code Style in Examples
152+
153+
- **Follow PEP 8** and project conventions
154+
- **Use meaningful variable names**
155+
- **Add comments** to explain complex steps
156+
- **Show intermediate results** to help debugging
157+
158+
## Common Issues and Solutions
159+
160+
### Build Errors
161+
162+
**Problem**: `ModuleNotFoundError` during build
163+
**Solution**: Install all dependencies with `pip install -e .[docs,dev]`
164+
165+
**Problem**: Examples fail to execute
166+
**Solution**:
167+
- Check that examples handle missing API keys gracefully
168+
- Ensure all required packages are imported
169+
- Test examples independently: `python docs/examples/plot_example.py`
170+
171+
**Problem**: MyST-NB execution errors
172+
**Solution**:
173+
- Check code cell syntax (triple backticks with `{code-cell} python`)
174+
- Verify notebook metadata in frontmatter
175+
- Test with: `jupyter-book build docs/tutorials/`
176+
177+
### Link Errors
178+
179+
**Problem**: Broken cross-references
180+
**Solution**: Use proper Sphinx references:
181+
- Functions: `:func:`pycancensus.get_census``
182+
- Tutorials: `:doc:`tutorials/getting_started``
183+
- External: `External Link <https://example.com>`_
184+
185+
## Continuous Integration
186+
187+
Documentation builds automatically on:
188+
- Every push to main/develop branches
189+
- Pull requests to main
190+
- Scheduled daily builds (to catch external dependency issues)
191+
192+
The CI workflow:
193+
1. Installs dependencies
194+
2. Builds documentation with `make html`
195+
3. Checks for broken links
196+
4. Fails if any errors occur
197+
198+
## Publishing
199+
200+
Documentation is published automatically to Read the Docs:
201+
- **Development**: Built from `develop` branch
202+
- **Stable**: Built from tagged releases
203+
- **Latest**: Built from `main` branch
204+
205+
### Read the Docs Configuration
206+
207+
The `.readthedocs.yaml` file configures:
208+
- Python version and dependencies
209+
- Build environment
210+
- Documentation format
211+
212+
## Performance Tips
213+
214+
### Fast Development Builds
215+
216+
```bash
217+
# Skip example execution during development
218+
export SPHINX_GALLERY_CONF_PLOT_GALLERY=False
219+
make html
220+
221+
# Build only specific sections
222+
sphinx-build -b html -D exclude_patterns="auto_examples/*" . _build/html
223+
```
224+
225+
### Caching
226+
227+
- **Jupyter Cache**: MyST-NB caches notebook execution results
228+
- **Sphinx Cache**: Reuses unchanged documentation
229+
- **Gallery Cache**: Sphinx-Gallery caches example outputs
230+
231+
Clear caches if you encounter stale content:
232+
```bash
233+
make clean-all
234+
rm -rf docs/_build/.jupyter_cache
235+
```
236+
237+
## Contributing Documentation
238+
239+
1. **Fork** the repository
240+
2. **Create** a feature branch for your documentation changes
241+
3. **Test** your changes locally with `make html`
242+
4. **Submit** a pull request with a clear description
243+
244+
