Cadl-Ranch scenario - Nonalpha chars are removed from parameter templates

[JoshLove-msft]

As an example, https://github.com/Azure/cadl-ranch/blob/main/packages/cadl-ranch-specs/http//routes/main.tsp#L226. But in our tspCodeModel.json, we have https://github.com/microsoft/typespec/blob/main/packages/http-client-csharp/generator/TestProjects/CadlRanch/http/routes/tspCodeModel.json#L1483. So either in TCGC or in the csharp emitter, these chars are being incorrectly removed.

Hi @JoshLove-msft
The Path here (corresponds to path property in TCGC) is by design to remove that dot character . because it is not part of the "path", but it is a feature of uri-template.
We did not do anything to it:

typespec/packages/http-client-csharp/emitter/src/lib/operation-converter.ts

Line 86 in db8af17

Path: method.operation.path,

It is known issue that we did not fully support uri-template feature. Currently we only support allow-reserved and explode.
Since we did not really adopt uri-template here, it would not help if we have its original route with the dot.
And FYI we could get the original route in the uriTemplate property from SdkHttpOperation.

Given this information, I think we might need to retriage this again and put it into a bucket of "supporting uri-template".
Also because of this situation, we cannot implement those various scenarios in http/routes.

Do we have any issues open for supporting uri-template? Do you mean that csharp emitter doesn't support it?

Ah I see it is filed here - #5561

Closing as this scenario is covered by #5561
