What happened?

starting with code of:

		const BUTTON_HEIGHT=100
		const scrollRect = scrollContainer.getBoundingClientRect()
		const isPartiallyVisible = rectCodeBlock.top < (scrollRect.bottom - BUTTON_HEIGHT) && rectCodeBlock.bottom >= (scrollRect.top + BUTTON_HEIGHT)

		// Calculate margin from existing padding in the component
		const computedStyle = window.getComputedStyle(codeBlock)
		const paddingValue = parseInt(computedStyle.getPropertyValue("padding") || "0", 10)
		const margin =
			paddingValue > 0 ? paddingValue : parseInt(computedStyle.getPropertyValue("padding-top") || "0", 10)

		// Get wrapper height dynamically
		let wrapperHeight
		if (copyWrapper) {
			const copyRect = copyWrapper.getBoundingClientRect()
			// If height is 0 due to styling, estimate from children
			if (copyRect.height > 0) {
				wrapperHeight = copyRect.height
			} else if (copyWrapper.children.length > 0) {
				// Try to get height from the button inside
				const buttonRect = copyWrapper.children[0].getBoundingClientRect()
				const buttonStyle = window.getComputedStyle(copyWrapper.children[0] as Element)
				const buttonPadding =
					parseInt(buttonStyle.getPropertyValue("padding-top") || "0", 10) +
					parseInt(buttonStyle.getPropertyValue("padding-bottom") || "0", 10)
				wrapperHeight = buttonRect.height + buttonPadding
			}
		}

		// If we still don't have a height, calculate from font size
		if (!wrapperHeight) {
			const fontSize = parseInt(window.getComputedStyle(document.body).getPropertyValue("font-size"), 10)
			wrapperHeight = fontSize * 2.5 // Approximate button height based on font size
		}

produced exactly, missing indentation:

const scrollRect = scrollContainer.getBoundingClientRect()

// Get wrapper height dynamically
let wrapperHeight
if (copyWrapper) {
	const copyRect = copyWrapper.getBoundingClientRect()
	// If height is 0 due to styling, estimate from children
	if (copyRect.height > 0) {
		wrapperHeight = copyRect.height
	} else if (copyWrapper.children.length > 0) {
		// Try to get height from the button inside
		const buttonRect = copyWrapper.children[0].getBoundingClientRect()
		const buttonStyle = window.getComputedStyle(copyWrapper.children[0] as Element)
		const buttonPadding =
			parseInt(buttonStyle.getPropertyValue("padding-top") || "0", 10) +
			parseInt(buttonStyle.getPropertyValue("padding-bottom") || "0", 10)
		wrapperHeight = buttonRect.height + buttonPadding
	}
}

// If we still don't have a height, calculate from font size
if (!wrapperHeight) {
	const fontSize = parseInt(window.getComputedStyle(document.body).getPropertyValue("font-size"), 10)
	wrapperHeight = fontSize * 2.5 // Approximate button height based on font size
}

const isPartiallyVisible = rectCodeBlock.top < (scrollRect.bottom - wrapperHeight) && rectCodeBlock.bottom >= (scrollRect.top + wrapperHeight)

Steps to reproduce

you could probably write a test using this to reproduce the problem

Relevant API REQUEST output

see above

Additional context

Note that the indentation in the resulting code is not completely lost - it appears that tab indentation within code blocks is preserved, but the leading indentation (the two tabs at the beginning of each line in the original code) is removed.

Issue: write_to_file tool truncates large files

Description:

The write_to_file tool consistently truncates files when writing content exceeding a certain size (approximately 285 lines in my testing). This prevents me from creating complete files, such as test suites, and hinders my ability to complete tasks effectively.

Steps to Reproduce:

1. Attempt to write a file with more than 285 lines using the write_to_file tool.
2. Observe that the resulting file is incomplete and truncated.

Expected Behavior:

The write_to_file tool should be able to write files of any size without truncation.

Workaround (if any):

Currently, there is no reliable workaround. Attempts to use apply_diff also fail due to the incomplete initial file. Splitting the content into smaller chunks and writing sequentially also fails.

Environment:

• Tool: write_to_file
• Project Directory: /root/Project/Xeenux
• Current Mode: code

Additional Information:

I have repeatedly tried to write the same file, and the truncation consistently occurs. This suggests a limitation within the tool itself.

The apply_diff tool failed because the diff format was incorrect. I apologize for the error. I will reconstruct the diff string with the correct format, including the <<<<<<< SEARCH, =======, and >>>>>>> REPLACE markers, and retry the apply_diff operation. I will also ensure the entire content is included in the diff.

can you open a new issue? your report is different than this open issue which specifically addresses indentation issues.
