unravel – Watching TeX digest tokens

The pack­age em­u­lates large parts of TeX’s be­haviour when it chews on to­kens, ex­pand­ing and per­form­ing type­set­ting com­mands. Us­ing un­ravel will let you go one step at a time through some com­pli­cated LaTeX code that you are try­ing to de­bug. It un­der­stands a whole breadth of TeX’s fea­tures, from deeply nested ex­pan­sion to box as­sign­ments, to char­ac­ters, and the proper in­ser­tion of \ev­ery­par.

The un­ravel pack­age re­quires up-to-date l3k­er­nel and l3­ex­per­i­men­tal bun­dles, as well as the new pack­age gtl.
