AZD hangs in WSL2 when running init --template

[khowling]

• Make sure you've installed the latest version using instructions in the wiki

Output from azd version
azd version 1.7.0 (commit 49d6adc)

Describe the bug
Running azd init --template webapp-mysql-dbjohn0isaac/flask-webapp-mysql-db , shows this output, and never returns a prompt or error (same for multiple different templates)

Initializing an app to run on Azure (azd init)

  |   ====| Downloading template code to: /home/xxxxxx/test/azd01

This is the same as issue : #460 , but that has been closed

Also, running azd to get the help screen, it says the command syntax is azd init --template [template name]. Running azd template list the Name is different from the Repository Path. I'm assuming you are not expecting the Name on the init command line?

To Reproduce
as above

Expected behavior
expect to either work, or return a error message

Environment
WIndows 11, running in WSL2 using Ubuntu.

More information:

As azd template list returns a long list! many linux users will pipe to grep to look for terms like python or appservice etc. Because you are returning a url formatted output, this appears to effect the output of grep. Thus I was putting in a none existing template url.

To reproduce: azd template list | grep python

this returns:

Microservices App - Dapr Bindings Cron Python ACA PostgreSQL                                   Awesome AZD  python-cron-postgresAzure-Samples/bindings-dapr-python-cron-postgres
Azure Functions - LangChain with Azure OpenAI and ChatGPT (Python v2 Function)                 Awesome AZD  python-ai-langchainAzure-Samples/function-python-ai-langchain
Azure Functions - Chat using ChatGPT (Python v2 Function)                                      Awesome AZD  python-ai-openai-chatgptAzure-Samples/function-python-ai-openai-chatgpt

Then running this Hangs, because the repo is not found

azd init --template python-cron-postgresAzure-Samples/bindings-dapr-python-cron-postgres

Suggested fixes for usability

• Implement a consistent template naming scheme, and ensure all cli help commands use it.
• Include in the template name host language/framework , other services (aoai, redis, mongo etc), and maybe a small paragraph of template description to describe what the template is, and when you should use it
• Handle the error if the template repo provided does not existing, rather than hanging the init command
• as there are so many templates, add additional param to the template list command, to filter by host, language, dependencies, features. For example list all templates that use mongo, or aoai

Looks like the clickable url links and its name/description is causing some issue on linux when grepping.

Seems to be working fine on mac.

azd template list | grep python-mongo-aca

on linux,

azd template list | grep python-mongo-aca

@weikanglim @vhvb1989 have you seen this?

@khowling , there might be a few alternatives for what you are doing.

1. azd built-in filter: When you run azd init and choose select a template, azd has a built-in filter that helps you to pick a template. Just type for searching, like:

You wouldn't need to run azd templates first for picking a template.

2. When you run azd templates, you can change the output to Json file, azd templates -o json. It might be easier to pipe and grep the output that way, as you can target the field you need, like azd template list -o json | grep -Po 'repositoryPath": "(.*python.*)"'

We did enhance the template listing experience with additionally pointing to the galleries for further searching, filtering capabilities as part of PR,
