• Draft comment:
  The regex for shell environment variables should not match escaped dollar signs, as this could lead to incorrect substitutions. Consider using a negative lookbehind to ensure the dollar sign is not escaped.

  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  The comment points out a real edge case in shell variable expansion where $ should be treated as a literal $ rather than a variable prefix. This could lead to incorrect substitutions if someone has escaped dollar signs in their strings. However, this is a relatively rare edge case, and the code is primarily focused on basic environment variable substitution. The current implementation matches VS Code's typical environment variable handling patterns.
  I might be underestimating the frequency of escaped dollar signs in real-world environment variable values. Also, if this is a standard shell behavior, maybe we should match it exactly.
  While escaped dollar signs are a valid concern, this is an edge case that can be addressed later if it becomes a real problem. The current implementation covers the main use cases.
  Delete the comment. While technically correct, it's suggesting a complex enhancement for an edge case that may not be worth the added complexity right now.

  Please specify a return type for the substituteSettingsVariables function to improve code clarity and maintainability. This applies to other utility functions as well if they exist.

  Comment was not on a valid diff hunk.

• Draft comment:
  Avoid abbreviating terms like 'env var'. Use 'environment variable' for clarity. This applies to other instances in the code as well.

  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  While the rule about not abbreviating terms is valid, this particular case appears in debug log messages which are only seen by developers debugging the code, not in user-facing text or API. Debug messages often use abbreviations for brevity. The comment also suggests changing other instances in the code which goes beyond the scope of this diff.
  The rule about abbreviations might be important for consistency across the codebase. Debug messages could be read by other developers who need to understand the system.
  Debug messages are a special case where brevity is often preferred, and "env var" is a widely understood abbreviation among developers. The comment also goes beyond the scope of the current changes.
  Delete the comment as it's overly pedantic for debug messages and goes beyond the scope of the current changes.

114-130: 🛠️ Refactor suggestion

Refactor the while loop to address static analysis warning.

The current implementation uses assignment within the while condition, which is flagged by static analysis. Consider refactoring to improve readability.

-    while ((matchResult = regexShellEnv.exec(value)) !== null) {
+    let shellMatch;
+    while ((shellMatch = regexShellEnv.exec(value)) !== null) {
-      const envVar = matchResult[1];
+      const envVar = shellMatch[1];

Handle potential pattern overlap and empty string values.

The code should:

1. Handle empty string values consistently with the first pattern.
2. Consider potential overlap between ${env:VAR} and $VAR patterns.

[error] 116-116: The assignment should not be in an expression.

The use of assignments in expressions is confusing.
Expressions are often considered as side-effect free.
