The most common automation tool is numbering, such as page numbers, chapter numbers, etc., which have been seen earlier.
More important automated layouts include catalogs, cross-references, references and vocabulary index tables,
Some can directly use the TX typesetting engine to complete the work, and some require other external programs.
These automated tools are also especially talked about by X
3.1 Master Record
3.1.1 Directory and chart directory
\ tableofcontents output
In the article, the format of the table of contents header is equivalent to a section starting with \ section: *,
In the report and book categories, the format of the directory title is equivalent to a chapter starting with \ chapter *, and the format of the directory title can be controlled according to the method in section 2.3.4.
\ listoffigures and \ listoftables collect the chart titles of the \ Caption command in the figure environment and table environment, and generate the table of contents of the table, the format is similar to the chapter table.
To generate the correct chapter catalog and chart catalog, you must compile the ex file at least twice without modifying the content
3.1.2 Control directory content
The principle of generating a directory.
Unlike many "advanced" typesetting tools that generate directories through special styles and search extraction functions, latex is implemented through a simple auxiliary file (see Figure 3.1).
When using chapter commands such as \ chapter, \ section,
The latex engine also writes the chapter number and title into a directory file with the extension .toc,
When encountering \ tableofcontents, latex will read the catalog file (if it exists) and generate the catalog.
The picture directory is a directory file with an extension of .lof,
The table directory is realized by a directory file with the extension .lot.
Three commands define each directory item,
The three parameters are directory level, numbered title and page number,
They are generated by the two \ sections in Example 3-1-1
\ numberline is used to output chapter numbers in \ contentsline.
