Hi Sébastien, thanks for the patch! I applied against master and tested it.
The compiler is complaining with In toplevel form: ob-tangle.el:196:1: Warning: Variable ‘modes’ left uninitialized Also, it breaks these two tests for me: 2 unexpected results: FAILED ob-tangle/block-order FAILED ob-tangle/continued-code-blocks-w-noweb-ref Let me know if you manage to pass all the test (or fix them...) and silent the warning. Thanks! -- Bastien
