What is makeinfo?

This file documents the use of the makeinfo program, versions 1.51 and later. It is an extract from the Texinfo manual.

makeinfo is a program for converting Texinfo files into Info files. Texinfo is a documentation system that uses a single source file to produce both on-line information and printed output.

You can read the on-line information using Info; type info to learn about Info. See the Texinfo manual, to learn about the Texinfo documentation system.

Controlling Paragraph Formats

In general, makeinfo fills the paragraphs that it outputs to an Info file. Filling is the process of breaking and connecting lines so that lines are the same length as or shorter than the number specified as the fill column. Lines are broken between words. With makeinfo, you can control:

Command Line Options

The following command line options are available for makeinfo.

-D var
Cause var to be defined. This is equivalent to @set var in the Texinfo file.

--error-limit limit
Set the maximum number of errors that makeinfo will report before exiting (on the assumption that continuing would be useless). The default number of errors that can be reported before makeinfo gives up is 100.

--fill-column width
Specify the maximum number of columns in a line; this is the right-hand edge of a line. Paragraphs that are filled will be filled to this width. The default value for fill-column is 72.

--footnote-style style
Set the footnote style to style, either `end' for the end node style or `separate' for the separate node style. The value set by this option overrides the value set in a Texinfo file by an @footnotestyle command. When the footnote style is `separate', makeinfo makes a new node containing the footnotes found in the current node. When the footnote style is `end', makeinfo places the footnote references at the end of the current node.

-I dir
Add dir to the directory search list for finding files that are included using the @include command. By default, makeinfo searches only the current directory.

Do not include menus or node lines in the output. This results in an ASCII file that you cannot read in Info since it does not contain the requisite nodes or menus; but you can print such a file in a single, typewriter-like font and produce acceptable output.

Suppress the splitting stage of makeinfo. Normally, large output files (where the size is greater than 70k bytes) are split into smaller subfiles, each one approximately 50k bytes. If you specify `--no-split', makeinfo will not split up the output file.

Suppress the pointer-validation phase of makeinfo. Normally, after a Texinfo file is processed, some consistency checks are made to ensure that cross references can be resolved, etc. See section Pointer Validation.

Suppress the output of warning messages. This does not suppress the output of error messages, only warnings. You might want this if the file you are creating has examples of Texinfo cross references within it, and the nodes that are referenced do not actually exist.

Supress automatic footnote numbering. By default, makeinfo numbers each footnote sequentially in a single node, resetting the current footnote number to 1 at the start of each node.

--output file
-o file
Specify that the output should be directed to file and not to the file name specified in the @setfilename command found in the Texinfo source. file can be the special token `-', which specifies standard output.

--paragraph-indent indent
Set the paragraph indentation style to indent. The value set by this option overrides the value set in a Texinfo file by an @paragraphindent command. The value of indent is interpreted as follows:

--reference-limit limit
Set the value of the number of references to a node that makeinfo will make without reporting a warning. If a node has more than this number of references in it, makeinfo will make the references but also report a warning.

-U var
Cause var to be undefined. This is equivalent to @clear var in the Texinfo file.

Cause makeinfo to display messages saying what it is doing. Normally, makeinfo only outputs messages if there are errors or warnings.

Report the version number of this copy of makeinfo.

Pointer Validation

If you do not suppress pointer-validation (by using the `--no-pointer-validation' option), makeinfo will check the validity of the final Info file. Mostly, this means ensuring that nodes you have referenced really exist. Here is a complete list of what is checked:

  1. If a `Next', `Previous', or `Up' node reference is a reference to a node in the current file and is not an external reference such as to `(dir)', then the referenced node must exist.

  2. In every node, if the `Previous' node is different from the `Up' node, then the `Previous' node must also be pointed to by a `Next' node.

  3. Every node except the `Top' node must have an `Up' pointer.

  4. The node referenced by an `Up' pointer must contain a reference to the current node in some manner other than through a `Next' reference. This includes menu entries and cross references.

  5. If the `Next' reference of a node is not the same as the `Next' reference of the `Up' reference, then the node referenced by the `Next' pointer must have a `Previous' pointer that points back to the current node. This rule allows the last node in a section to point to the first node of the next chapter.
