rubber-info — extract information from LaTeX documents


rubber-info [options] [action] source


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).

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


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.


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


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.


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


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

-h, --help

Display the list of all available options and exit nicely.


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


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.


Print the version number and exit nicely.


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