Munehiro Yamamoto submitted an update to the

runtexshebang

package.

Version: 1.1 2026-10-21 License: lppl1.3c

Summary description: A Lua script running LaTeX document files with TeX-style shebang

Announcement text: -------------------------------------------------------------------------------- runtexshebang v1.1 refuses a TeX-style shebang (%#!) line that contains an ASCII control character other than TAB, both when running it and with --dry-run. A carriage return or an escape sequence in that line could make the command shown on the terminal differ from the command the shell actually runs. Non-ASCII bytes are not checked, so UTF-8, Shift_JIS and EUC-JP file names keep working.

The test suite now also checks that runtexshebang never loads Lua modules placed in the current directory.

runtexshebang 1.0 runs the `%#!` line of a LaTeX document through the system shell, as before, but is now more careful about it.

## Changes

- The license is now the LaTeX Project Public License 1.3c (was MIT). - The command of the `%#!` line is printed on stderr before it is run, and its exit status is passed through, so editors and `make` can detect failures. - CRLF line endings and a UTF-8 byte order mark before `%#!` are handled; only the leading `%#!` is removed from the line. - Missing files, an empty `%#!` line and unknown options are reported with a message and a non-zero exit status instead of a Lua traceback. `--` ends option parsing. - On Windows, `NoDefaultCurrentDirectoryInExePath=1` is set before the command runs, so an executable placed next to the document cannot shadow a TeX Live program named on the `%#!` line. - The README has a new Security section. In short: running runtexshebang on a document is equivalent to typing its `%#!` line yourself, so use it only on documents you trust, and never add it to `shell_escape_commands`. - PDF documentation is included. --------------------------------------------------------------------------------
