# TASK-058: The outline was empty for C++ written on Windows

Status: implemented; required checks pass; confirmed by the human product owner on their Z Fold7 (2026-09-29)
Owner: Claude
Reviewer: human product owner

## Outcome

The human product owner reported that a `.cpp` and its `.h` showed no classes or functions in the
side pane, although both plainly contain them.

## Cause

Reproduced in a unit test, not on the owner's files (their repository is private and was not read).

1. Lines ending in `\r\n`. The viewer split text on `\n` only, so every line of a file written on
   Windows ended in an invisible `\r`. The patterns that recognize a method must match a whole
   line, and `.` does not match `\r`, so no method was ever recognized -- in C++ and in C# alike.
   A class was still found, because that pattern only has to match the start of the line. A `.cpp`
   holding only function definitions therefore had an empty outline.
2. Found while reproducing, in MFC-style code: a macro in a class body (`DECLARE_MESSAGE_MAP()`)
   was listed as a method, and because it has no `;` the declaration on the next line was skipped.
3. Found while reproducing: a block opened in both branches of an `#if`/`#else` was counted twice,
   leaving a scope that never closed; every function after it in the file was missing.

## Scope

- Included: the three causes above, with a test for each.
- Excluded: declarations produced by macros, and declarations split across lines before their
  name. The outline recognizes patterns; it is not a parser.

## Writable paths

- `app/src/main/java/com/ubisam/ubgitea/feature/codebrowser/`
- `app/src/test/java/com/ubisam/ubgitea/feature/codebrowser/`
- `tasks/`, `docs/`

## Acceptance criteria

- [x] A header, a source file and a C# file with `\r\n` line endings list their methods.
- [x] A capitalized macro in a class body is not listed and does not hide what follows it.
- [x] A block opened in each branch of a conditional is counted once.

## Security and privacy

No additional concerns.

## Required checks

```text
./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug
```

## Evidence

- Required checks pass: 435 unit tests, 0 failures; lint 0 errors.
- Installed on the SM-F966N over wireless `adb`.
- Not verified against the files the product owner was reading. If their outline is still empty,
  the cause is something these three do not cover, and a sample of the file is needed.

## Known limitations

- A header whose class showed nothing at all is not explained by cause 1, which still finds
  classes. It may be explained by the owner looking at the `.cpp`'s outline while both were open.
- "Copy" is unchanged: it copies the file's text as received, `\r\n` included.
