# rubber-info(1)

extract information from LaTeX documents

## NAME

rubber-info - extract information from LaTeX documents

## SYNOPSIS

**rubber-info** \[*options*\] \[*action*\] *source*

## DESCRIPTION

Rubber-info is a utility for extracting various kinds of information from a LaTeX document. Information can be extracted from the source (for instance when calculating dependencies) or from the compilation log files (to extract errors and warnings). This program is a complement for the compilation system [**rubber**(1)](/rubber/1.md).

The command-line options are those used by [**rubber**(1)](/rubber/1.md) plus one of the actions described below.

## ACTIONS

One of the following command-line options must be specified, to decide which information to extract. Of course, for actions that read a log file, a compilation must have been done before. If none of these actions is specified, *--check* is assumed.

- **--boxes**

  Extracts from the log file the places in the source where bad boxes appeared (these are the famous overfull and underfull \\hbox and \\vbox)

- **--check**

  Report errors if there are any, otherwise report undefined references if there are any, otherwise list warnings and bad boxes. This is the default action.

- **--deps**

  Analyse the source files and produce a space-separated list of all the files that the document depends on and that Rubber cannot rebuild.

- **--errors**

  Extract from the log file the list of errors that occurred during the last compilation.

- **-h, --help**

  Display the list of all available options and exit nicely.

- **--refs**

  Report the list of undefined or multiply defined references (i.e. the \\ref's that are not defined by one \\label).

- **--rules**

  Analyse the source files and produce a list of dependency rules. One rule is produced for each intermediate target that would be made when running **rubber**. Rules are formatted in the style of Makefiles.

- **--version**

  Print the version number and exit nicely.

- **--warnings**

  Stupidly enumerate all LaTeX warnings, i.e. all the lines in the log file that contain the string "Warning".
