🚀 Data Size Count v4.0.0 - The Ultimate Release!

December 15, 2025 — We're thrilled to announce the biggest update to Data Size Count yet! This major release brings powerful new features, a completely redesigned architecture, and an enhanced user experience.

✨ What's New in v4.0.0

🔍 Custom Regex Pattern Counting

Count anything in your code with powerful regex-based pattern matching. Track imports, exports, comments, TODOs, console logs, and more—all directly in your status bar!

{
  "data-size-count.statusBar.regexCount": [
    {
      "title": "Imports",
      "format": "$(cloud-download) ${matchCount} Imports",
      "regex": "^\\s*import\\b.*$"
    },
    {
      "title": "TODOs",
      "format": "$(checklist) TODOs: ${matchCount}",
      "regex": "TODO"
    }
  ]
}

📊 Advanced Selection Analytics

Get deeper insights into your selections with brand new metrics:

Empty Line Count – Detect blank lines in selections
Duplicate Lines – Identify repeated lines (useful for cleanup)
Duplicate Words – Find repeated words in your text
Max Depth – Understand nesting levels in JSON/objects
Unique Data Count – Count unique items in arrays

🎯 Modular Status Bar Architecture

The status bar now uses intelligent, independent modules:

FileSizeItem – Always shows current file size
SelectionItem – Displays rich selection metrics when text is selected
RegexItem – Shows custom regex pattern matches
StatusbarManager – Orchestrates all items seamlessly

Each module can be independently customized and controlled.

📄 New Combined Details View

Click your status bar to see a beautifully formatted popup with:

📄 File information (path, size, language)
✂️ Selection details (all metrics in one place)
🔎 Regex match counts
🕘 Timestamp

🎁 Enhanced Features

Better Format Variables

More control over how metrics are displayed:

${emptyLineCount} – Empty lines in selection
${duplicateLinesCount} – Duplicate line count
${duplicateWordsCount} – Duplicate word count
${maxDepth} – Maximum nesting depth
${uniqueDataCount} – Unique items in arrays
${matchCount} – Regex pattern matches

Improved Defaults

Out-of-the-box better experience:

{
  "data-size-count.statusBar.fileSizeFormat": "$(file-text) ${fileSize}",
  "data-size-count.statusBar.selectedSizeFormat": "$(selection) ${selectedSize}",
  "data-size-count.statusBar.selectionCountFormat": "${linesCount} : ${wordsCount} : ${charCount}",
  "data-size-count.statusBar.dataCountFormat": "$(database) ${dataCountWithBrackets} / ${maxDepth}",
  "data-size-count.statusBar.position": "Left",
  "data-size-count.statusBar.priority": -1
}

Smart Separators

Control how metrics are separated with:

data-size-count.statusBar.selectionMetricsSeparator – Between selection metrics (default: " | ")
data-size-count.statusBar.regexCountSeparator – Between regex counts (default: ", ")

🔄 Breaking Changes

Visibility Setting Removed

The old visibility object setting has been removed. To hide metrics, simply set their format to an empty string:

{
  "data-size-count.statusBar.fileSizeFormat": "",  // Hide file size
  "data-size-count.statusBar.selectedSizeFormat": "", // Hide selected size
  "data-size-count.statusBar.selectionCountFormat": "${linesCount} : ${wordsCount}", // Show only lines & words
  "data-size-count.statusBar.dataCountFormat": "" // Hide data count
}

Command Renamed

Old: data-size-count.showFileDetails
New: data-size-count.showCombinedDetails

This command now opens the beautiful combined details popup.
