Chat - Formatting is incorrect when pasting code into the compose box by nkdengineer · Pull Request #63426 · Expensify/App

nkdengineer · 2025-06-04T09:35:32Z

Explanation of Change

This PR fixes the extra space between lines when pasting code.

Fixed Issues

Tests

Copy the text

 if (files.length > 0) { 
     // Prevent the default so we do not post the file name into the text box 
     event.preventDefault(); 
     this.props.onPasteFile(event.clipboardData.files[0]); 
     return;

Navigate to the Expensify app
Paste the code into the compose box in a conversation
For iOS native: an empty line is added, it's the same as Slack
For other platforms: the pasted code should retain original formatting:

No extra space between lines.
All lines left-aligned as in the source code.
Verify that no errors appear in the JS console

Offline tests

Same as tests

QA Steps

@ZhenjaHorbach I see this issue is not fixed on iOS native. This issue also happens on Slack iOS native (not other platforms), so I think we can ignore it

nkdengineer · 2025-06-06T03:26:42Z

@ZhenjaHorbach Can you help review my PR?

Weird
As far as I can see, this is a regular empty line
But where could it come from?

Reviewer Checklist

I have verified the author checklist is complete (all boxes are checked off).
I verified the correct issue is linked in the ### Fixed Issues section above
I verified testing steps are clear and they cover the changes made in this PR
- I verified the steps for local testing are in the Tests section
- I verified the steps for Staging and/or Production testing are in the QA steps section
- I verified the steps cover any possible failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
- I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
I checked that screenshots or videos are included for tests on all platforms
I included screenshots or videos for tests on all platforms
I verified that the composer does not automatically focus or open the keyboard on mobile unless explicitly intended. This includes checking that returning the app from the background does not unexpectedly open the keyboard.
I verified tests pass on all platforms & I tested again on:
- Android: HybridApp
- Android: mWeb Chrome
- iOS: HybridApp
- iOS: mWeb Safari
- MacOS: Chrome / Safari
- MacOS: Desktop
If there are any errors in the console that are unrelated to this PR, I either fixed them (preferred) or linked to where I reported them in Slack
I verified there are no new alerts related to the canBeMissing param for useOnyx
I verified proper code patterns were followed (see Reviewing the code)
- I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick).
- I verified that comments were added to code that is not self explanatory
- I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
- I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
- I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
- I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
- I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
- I verified the JSDocs style guidelines (in STYLE.md) were followed
If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
I verified that this PR follows the guidelines as stated in the Review Guidelines
I verified other components that can be impacted by these changes have been tested, and I retested again (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar have been tested & I retested again)
I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
If a new component is created I verified that:
- A similar component doesn't exist in the codebase
- All props are defined accurately and each prop has a /** comment above it */
- The file is named correctly
- The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
- The only data being stored in the state is data necessary for rendering and nothing else
- For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
- Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
- All JSX used for rendering exists in the render method
- The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
If any new file was added I verified that:
- The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
If a new CSS style is added I verified that:
- A similar style doesn't already exist
- The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG)
If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
- I verified that all the inputs inside a form are aligned with each other.
- I added Design label and/or tagged @Expensify/design so the design team can review the changes.
If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
For any bug fix or new feature in this PR, I verified that sufficient unit tests are included to prevent regressions in this flow.
If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.
I have checked off every checkbox in the PR reviewer checklist, including those that don't apply to this PR.

nkdengineer · 2025-06-09T04:01:21Z

But where could it come from?

Maybe, iOS automatically add the new line when this.props.onPasteFile(event.clipboardData.files[0]); contains many space at the beginning

nkdengineer · 2025-06-09T05:18:28Z

I think this issue happens on Slack as well so we can ignore it. What about you @ZhenjaHorbach ?

nkdengineer · 2025-06-10T03:17:41Z

All good? @ZhenjaHorbach

ZhenjaHorbach · 2025-06-10T18:30:16Z

Let's update description in this case
And mention that an empty line is added to iOS

nkdengineer · 2025-06-11T03:58:11Z

@ZhenjaHorbach I updated the test steps. Thank you

ZhenjaHorbach · 2025-06-11T16:55:30Z

@ZhenjaHorbach I see this issue is not fixed on iOS native. This issue also happens on Slack iOS native (not other platforms), so I think we can ignore it

@MonilBhavsar
Could you provide your thoughts about it, please ?

nkdengineer · 2025-06-13T01:49:22Z

@MonilBhavsar This issue is not fixed on native iOS, I checked on Slack iOS and I see the same thing, but on other platforms they are not, so should we ignore it on iOS

nkdengineer · 2025-06-17T03:01:25Z

@MonilBhavsar What do you think?

nkdengineer · 2025-06-19T02:08:01Z

@ZhenjaHorbach It looks like we haven't received a response. What should we do next?

ZhenjaHorbach · 2025-06-19T07:17:42Z

@ZhenjaHorbach It looks like we haven't received a response. What should we do next?

I pinged in slack

MonilBhavsar · 2025-06-19T18:02:20Z

Sorry for missing this.
Is it a known react native issue?
Wonder how other platforms except slack are working around this problem.

nkdengineer · 2025-06-20T03:33:04Z

Wonder how other platforms except slack are working around this problem.

I tested on other platforms like Messenger, Discord and Whatsapp, this issue happens on all platforms

For Slack, it just happens on iOS Native.

Not sure what platform we should follow

@MonilBhavsar @ZhenjaHorbach What do you think about my comment here #63426 (comment)?

ZhenjaHorbach · 2025-06-24T06:47:28Z

@MonilBhavsar @ZhenjaHorbach What do you think about my comment here #63426 (comment)?

I don't think this is a critical issue
And since this issue exists in several apps
Then I think it's normal
LGTM from my side

nkdengineer · 2025-06-27T02:19:25Z

@MonilBhavsar Can you please take a look?

MonilBhavsar

Fine for me 👍
Thanks!
