📝 Walkthrough

Walkthrough

This pull request contains three separate script modifications. The first change adjusts print output behavior by removing the default newline appended by print statements. The second change converts a global variable to lexically scoped within a subroutine. The third change upgrades file input/output operations to use explicit mode arguments in open statements and replaces backtick command execution with piped subprocess invocation to capture output. All modifications maintain existing logic while refining implementation details across output handling, variable scoping, and file I/O practices.

Inline comments:
In `@html-update-toc`:
- Around line 134-137: The code opens a pipe to run "$script_dir/html-toc" and
reads into $newcontent but never checks close($toc_pipe), risking writing
partial/empty content; modify the code after reading $newcontent to check
close($toc_pipe) and die (or abort the rewrite) when the child failed, including
either $! or the child's exit status $? in the error message so you get "Error
closing pipe: $!" or "html-toc failed for $file (exit status: $?)", and ensure
you do not proceed to overwrite the file with $newcontent if the close indicates
failure.
