It opens group, reduces `\_leftskip`, `\_rightskip`, runs the \^`\everytocline` (user can customise the design of TOC here) and runs `\_tocl:<level> {<number>}{<title>}{<pageno>}` macro. This macro starts with vertical mode, inserts one record with given `<level>` and it should end by \^`\_tocpar` which returns to hrizontal mode. The `\_tocpar` appends `\_nobreak \_hskip-2\_iindent\_null \_par`. This causes that the last line of the record is shifted outside the margin given by `\_rightskip`. A typical record (with long `<title>`) looks like: \begtt | | \llap{<number>} text text text text text text text text text text text text .................... <pageno> \endtt Margins given by `\leftskip` and `\rightskip` are denoted by `|` in the examle above. \nl \`\tocrefnum` is global counter of all TOC records (used by hyperlinks). \_cod ------------------------------------ \_newcount \_tocrefnum \_def\_tocline#1#2#3#4#5#6{% \_advance\_tocrefnum by1 \_bgroup \_leftskip=\_iindent \_rightskip=2\_iindent \_ifischap \_advance\_leftskip by \_iindent \_fi \_def\_pgn{\_ilink[pg:#5]}% \_the\_everytocline \_ifcsname _tocl:#1\_endcsname \_cs{_tocl:#1}{#3}{#4}{#6}\_par \_fi \_egroup } \_public \tocrefnum ; \_doc ----------------------------------- You can re-define default macros for each level of tocline if you want.\nl Parameters are `{<number>}{<title>}{<pageno>}`. \_cod ----------------------------------- \_sdef{_tocl:1}#1#2#3{\_nofirst\_bigskip \_bf\_llaptoclink{#1}{#2}\_hfill \_pgn{#3}\_tocpar} \_sdef{_tocl:2}#1#2#3{\_llaptoclink{#1}{#2}\_tocdotfill \_pgn{#3}\_tocpar} \_sdef{_tocl:3}#1#2#3{\_advance\_leftskip by\_iindent \_cs{_tocl:2}{#1}{#2}{#3}} \_doc ----------------------------------- The auxiliary macros are: \begitems * \`\_llaptoclink``<text>` does `\_noindent\_llap{<linked text>}`. * \`\_tocdotfill` creates dots in the TOC. * \`\_nofirst``\macro` applies the `\macro` only if we don't print the first record of the TOC. * \`\_tocpar` finalizes one TOC recors whith rlapped `<pageno>`. * \`\_pgn``{<pageno>}` creates <pageno> as link to real `<gpage>` saved in `#6` of \^`\_tocline`.
