- `/db/table-.csv` - the HTML version
- `/db/table-.csv.csv` - the CSV version
- `/db/table-.csv.json` - the JSON version

And if for some horific reason you had a table with the name `/db/table-.csv.csv` (so `/db/` was the first part of the actual table name in SQLite) the URLs would look like this:

- `/db/%2Fdb%2Ftable---.csv-.csv` - the HTML version
- `/db/%2Fdb%2Ftable---.csv-.csv.csv` - the CSV version
- `/db/%2Fdb%2Ftable---.csv-.csv.json` - the JSON version","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",973139047,Rethink how .ext formats (v.s. ?_format=) works before 1.0,

```python

    return s.replace(""-."", ""."").replace(""--"", ""-"")

```python
for example in (

I actually did this once before, in https://github.com/simonw/datasette/commit/9fdb47ca952b93b7b60adddb965ea6642b1ff523 - while I was working on porting Datasette to ASGI in https://github.com/simonw/datasette/issues/272#issuecomment-494192779 because ASGI didn't yet have the `raw_path` mechanism.

I could bring that back - it looked like this:

```
    ""table/and/slashes"" => ""tableU+002FandU+002Fslashes""
    ""~table"" => ""U+007Etable""
    ""+bobcats!"" => ""U+002Bbobcats!""
    ""U+007Etable"" => ""UU+002B007Etable""
```
But I didn't particularly like it - it was quite verbose.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",973139047,Rethink how .ext formats (v.s. ?_format=) works before 1.0,

The obvious way to do this would be URL-encoding - but it doesn't hold for `.` characters. The hex for that is `%2E` but watch what happens with that in a URL:

```
# Against Cloud Run:
curl -s 'https://datasette.io/-/asgi-scope/foo/bar%2Fbaz%2E' | rg path
 'path': '/-/asgi-scope/foo/bar/baz.',
 'raw_path': b'/-/asgi-scope/foo/bar%2Fbaz.',
 'root_path': '',
# Against Vercel:
curl -s 'https://til.simonwillison.net/-/asgi-scope/foo/bar%2Fbaz%2E' | rg path
 'path': '/-/asgi-scope/foo/bar%2Fbaz%2E',
 'raw_path': b'/-/asgi-scope/foo/bar%2Fbaz%2E',
 'root_path': '',
```
Surprisingly in this case Vercel DOES keep it intact, but Cloud Run does not.

It's still no good though: I need a solution that works on Vercel, Cloud Run and every other potential hosting provider too.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",973139047,Rethink how .ext formats (v.s. ?_format=) works before 1.0,
