NAME

SYNOPSIS

DESCRIPTION

The columns specified by the user (see the -column option, below) are used of the left hand side of the output. Two additional columns are always added: the line number and the source code.

If no columns are specified, the default columns are

At the end of the listing, accumulated statistics are presented, correlated to the unique columns values see in the listing.

OPTIONS

-COLumn formula [ heading ][ width ]

This option may be used to specify columns you wish to see in the output. The formula is in the for of an aesub(5) string. The heading is a string to be used as the column heading; defaults to the formula if not specified. The width is the width of the columns; defaults to 7 if not specified.

-File_Statistics

This option causes file statistics to be appended. This lists the number of lines in the file were changed at the same time as another file. For example, this allows you to see tests associated with source files, and vice versa.

-Help

This option may be used to obtain more information about how to use the aeannotate program.

-Diff_Option string

This option may be used to pass addition arguments to the diff commands that is run between each delta of the file. Use with caution: poor choice of options can render aeannotate inoperable, or yield meaningless results. Probably the best use of this option is to pass the -b option, to ignore white space changes, because this ignores the vast majority of cosmetic formatting changes, showing you the content changes instead. The -i option, to ignore case, can also be useful for case‐insensitive languages.

-Output filename

This option may be used to specify the output file. The output is sent to the standard output by default.

-Project name

This option may be used to select the project of interest. When no -Project option is specified, the AEGIS_PROJECT environment variable is consulted. If that does not exist, the user's $HOME/.aegisrc file is examined for a default project field (see aeuconf(5) for more information). If that does not exist, when the user is only working on changes within a single project, the project name defaults to that project. Otherwise, it is an error.

See also aegis(1) for options common to all aegis commands.

All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. You must use consecutive sequences of optional letters.

All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important.

For example: the arguments “-project”, “-PROJ” and “-p” are all interpreted to mean the -Project option. The argument “-prj” will not be understood, because consecutive optional characters were not supplied.

Options and other command line arguments may be mixed arbitrarily on the command line, after the function selectors.

The GNU long option names are understood. Since all option names for aeannotate are long, this means ignoring the extra leading '-'. The “--option=value” convention is also understood.

EXAMPLES

If you wanted to list the developer and the reviewer against the lines of the file (commonly called a “blame” listing) use this column specification:

If you wanted to see the change cause of each line, use this column specification:

All of the aesub(5) substitutions are available, however only the ${change ...} variants are particularly useful.

To see only content changes, and ignore changes in indentation (assuming you are using GNU diff), use this command:
