Preprocess input tables

mkdocs>=1.4 supports hooks, which enable you to run python scripts on mkdocs serve or mkdocs build.

Here are some example of workflows that use hooks and the table-reader plugin:

Combine a directory of tables into a single, larger table.

from os import listdir
from os.path import isfile, join
import pandas as pd

def on_pre_build(config, **kwargs) -> None:
    tables = []
    input_files = [f for f in listdir(mypath) if isfile(join(mypath, f))]
    for table in input_files:
        tables.append(pd.read_csv(table))
    df = pd.concat(tables, ignore_index=True)
    df.to_csv("docs/assets/output_table.csv")

My table: {{ read_csv("docs/assets/output_table.csv") }} 

# ...
plugins:
    - table-reader
hooks:
    - scripts/hooks.py
# ...

.
├── scripts/

├── docs/
│   └─── index.md
│   └── assets/tables/
│       └── table1.csv
│       └── table2.csv
└── mkdocs.yml

Download a table from an API

import pandas as pd

def on_pre_build(config, **kwargs) -> None:
    df = pd.read_csv('https://data.cityofnewyork.us/resource/nu7n-tubp.csv?$limit=100')
    df.to_csv("docs/assets/nyc_data.csv")

My table: {{ read_csv("docs/assets/nyc_data.csv") }} 

# ...
plugins:
    - table-reader
hooks:
    - scripts/hooks.py
# ...

.
├── scripts/
│   └─── hooks.py
├── docs/
│   └─── index.md
│   └── assets/
└── mkdocs.yml

Note that during development when you use mkdocs serve and autoreload, you might not want to run this hook every time you make a change. You could use an environment variable inside your hook, for example something like if os.environ['disable_hook'] == 1: return None.
