1816917522,PR_kwDOCGYnMM5WJ6Jm,573,feat: Implement a prepare_connection plugin hook,15178711,closed,0,,,4,2023-07-22T22:48:44Z,2023-07-22T22:59:09Z,2023-07-22T22:59:09Z,CONTRIBUTOR,simonw/sqlite-utils/pulls/573,"Just like the [Datasette prepare_connection hook](https://docs.datasette.io/en/stable/plugin_hooks.html#prepare-connection-conn-database-datasette), this PR adds a similar hook for the `sqlite-utils` plugin system. 

The sole argument is `conn`, since I don't believe a `database` or `datasette` argument would be relevant here. 

I want to do this so I can release `sqlite-utils` plugins for my [SQLite extensions](https://github.com/asg017/sqlite-ecosystem), similar to the Datasette plugins I've release for them. 

An example plugin: https://gist.github.com/asg017/d7cdf0d56e2be87efda28cebee27fa3c

```bash
$ sqlite-utils install https://gist.github.com/asg017/d7cdf0d56e2be87efda28cebee27fa3c/archive/5f5ad549a40860787629c69ca120a08c32519e99.zip

$ sqlite-utils memory 'select hello(""alex"") as response'
[{""response"": ""Hello, alex!""}]
```
