[tienifr]

This PR enables indented text to show as is (do not trim the spaces) in quotes.

Fixed Issues

$ Expensify/App#38156

Tests

1. What unit/integration tests cover your change? What autoQA tests cover your change?

The ExpensiMark-HTML-test.js is updated to include the new test cases and modify existing tests to match with new expected behaviors.

2. What tests did you perform that validates your changed worked?

• Run the unit test.
• Test in Expensify App follow these steps:

1. Send a quote message with indentation:

> No indent
>     Indented 4

2. Verify the Indented 4 line shows with 4-space indentation in quote

QA

1. What does QA need to do to validate your changes?

Test in Expensify App follow these steps:

1. Send a quote message with indentation:

> No indent
>     Indented 4

2. Verify the Indented 4 line shows with 4-space indentation in quote

2. What areas to they need to test for regressions?

Inconsistency, send the following message:

> k
>>       hi         
>       hi there        
> k

Notice that there are spaces after both hi and hi there. But when the message is sent we are trimming the spaces only on the nested quote (the hi message)

.

@s77rt I want to confirm the expected behavior:

1. Allow leading spaces; trim the trailing and the ones between >
2. Allow spaces in both ends; trim the spaces between >

1️⃣ or 2️⃣?

[s77rt]

@tienifr I don't have a strong preference, as long as we have consistency it should be good enough. Perhaps 2️⃣ is a better fit here

[s77rt]

@tienifr Any progress on this?

[tienifr]

@s77rt I forgot about the case where there're trailing spaces at the end of the whole quote. If we follow 2️⃣ above, we can opt in to keep (1) or trim (2) these spaces. For example:

>⎵⎵⎵quote⎵
>⎵⎵trailing⎵⎵

Output can either be

(1) <blockquote>⎵⎵quote⎵<br />⎵trailing⎵⎵</blockquote>

or

(2) <blockquote>⎵⎵quote⎵<br />⎵trailing</blockquote>

I have solutions for both but (2) will add one more conditional statements.

1. Allow leading spaces; trim the trailing and the ones between >

After all, I think this is the best option 😄 We can avoid increased code complexity, maintain consistency but still achieve the expected behavior. Current implementation also trim trailing spaces.

[tienifr]

So we still keep both trailing and leading spaces, right?

@s77rt from your conversation above this sounds the best option. Can you please confirm so we can finish up this PR. Thanks

[s77rt]

Yes, we won't alter user input on quotes
