Walkthrough

The cleanupCode function in code-viewer.ts is updated to remove complete multiline @DemoSource blocks using parenthesis-aware preprocessing, replacing the previous per-line filtering approach.

Changes

Cohort / File(s)	Summary
Code cleanup logic enhancement base/src/main/resources/META-INF/resources/frontend/code-viewer.ts	Updated cleanupCode to preprocess multiline @DemoSource(...) blocks by nulling lines while tracking parenthesis balance, then removed the explicit @DemoSource exclusion from the final filter.

In `@base/src/main/resources/META-INF/resources/frontend/code-viewer.ts`:
- Around line 328-335: The `@DemoSource` removal code only looks for '(' on the
same line; instead compute a parenthesis balance for the annotation start (count
'(' minus ')' on the current line) and if balance > 0 iterate forward updating
balance with counts of '(' and ')' on each subsequent line, setting each visited
lines[k] = null until balance <= 0 or end of file; if balance == 0 just null the
single line. Update the block that inspects lines[i] (the `@DemoSource` handling
loop using variables lines and i) to use this parenthesis-balance loop so
wrapped annotations spanning multiple lines are fully removed.
