\_codedecl \maketoc {Macros for maketoc <2020-03-12>} % preloaded in format
\_doc ------------------------------------
`\_Xtoc{<level>}{<type>}{<number>}{<text>}` (in `.ref` file) reads the
specified data and saves it to the `\_toclist` as:
\begtt
\_tocline{<level>}{<type>}{<number>}{<text>}{<gpageno>}{<pageno>}
where:
<level>: 0 reserved, 1: chapter, 2: section, 3: subsection
<type>: the type of the level, i.e. chap, sec, secc
<number>: the number of the chapter/section/subsection in the format 1.2.3
<text>: the title text
<gpageno>: the page number numbered from 1 independently of pagination
<pageno>: the page number used in the pagination
\endtt
The last two parameters are restored from previous
`\_Xpage{<pageno>}{<gpageno>}`, data are saved in the `\_currpage` macro.
\_cod ------------------------------------
\_def\_toclist{}
\_newifi \_ifischap \_ischapfalse
\def\_Xtoc#1#2#3#4{\_ifnum#1=0 \_ischaptrue\_fi
\_addto\_toclist{\_tocline{#1}{#2}{#3}{#4}}
\_ea\_addto\_ea\_toclist\_ea{\_currpage}%
}
\_doc ------------------------------------
`\_tocline{<level>}{<type>}{<number>}{<text>}{<gpageno>}{<pageno>}` prints
the record to the table of contents. It opens group, reduces `\_leftskip`,
`\_rightskip`, runs the `\everytocline` (user can customise the design of TOC
here) and runs `\_tocl:<level> {<number>}{<text>}{<page>}` macro.
This macro starts with vertical mode,
inserts one record with given <level> and ends in horizontal mode. Then
`\_tocline` 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 <text>) 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.
\_cod ------------------------------------
\def\_tocline#1#2#3#4#5#6{%
\_advance\_tocrefnum by1
\_bgroup
\_leftskip=\_iindent \_rightskip=2\_iindent
\_ifischap \_advance\_leftskip by \_iindent \_fi
\_def\_pg{\_ilink[pg:#5]}%
\_the\_everytocline
\_ifcsname _tocl:#1\_endcsname
\_cs{_tocl:#1}{#3}{#4}{#6}\_nobreak \_hskip-2\_iindent\_null \_par
\_fi
\_egroup
}
\_doc -----------------------------------
You can re-define default macros for each level of tocline if you want:
\_cod -----------------------------------
\_sdef{_tocl:1}#1#2#3{\_nofirst\_bigskip \_bf\_llaptoclink{#1}{#2}\_hfill \_pg{#3}}
\_sdef{_tocl:2}#1#2#3{\_llaptoclink{#1}{#2}\_tocdotfill \_pg{#3}}
\_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.
* `\_pg{<pageno>}` creates <pageno> as link to real <gpage> saved in `#6`
of `\tocline`.
\enditems
\_cod ----------------------------------
\_def\_llaptoclink#1{\_noindent
\_llap{\_ilink[toc:\_the\_tocrefnum]{\_enspace#1\_kern.4em}\kern.1em}}
\_def\_tocdotfill{\_nobreak\_leaders\_hbox to.8em{\_hss.\_hss}\_hskip 1em plus1fill\_relax}
\_def\_nofirst #1{\_ifnum \_lastpenalty=11333 \_else #1\_fi}
\_doc -----------------------------------
`\maketoc` prints warning if TOC data is empty, lse it creates TOC by
running `\_toclist`
\_cod ----------------------------------
\_def\_maketoc{\_par \_ifx\_toclist\_empty
\_opwarning{\_noexpand\maketoc -- data unavailable, TeX me again}\_openref
\_else \_begingroup
\_tocrefnum=0 \_penalty11333
\_the\_regtoc \_toclist
\_endgroup \_fi
}
\_doc -----------------------------------
`\regmacro` appends its parameters to `\_regtoc`, `\_regmark` and
`\_regoul`. These token lists are used in `\maketoc`, `\_begoutput` and
`\pdfunidef`.
\_cod \_fin -----------------------------
\_newtoks \_regtoc \_newtoks \_regmark \_newtoks \_regoul
\_def\_regmacro #1#2#3{%
\_toksapp\_regtoc{#1}\_toksapp\_regmark{#2}\_toksapp\_regoul{#3}%
}
\_public \maketoc \regmacro ;
\_endcode
