14.1.1 Output File Control

gnatmetric has two output formats. It can generate a textual (human-readable) form, and also XML. By default only textual output is generated.

When generating the output in textual form, gnatmetric creates for each Ada source file a corresponding text file containing the computed metrics. By default, this file is placed in the same directory as where the source file is located, and its name is obtained by appending the .metrix suffix to the name of the input file.

All the output information generated in XML format is placed in a single file. By default this file is placed in the current directory and has the name metrix.xml.

Some of the computed metrics are summed over the units passed to gnatmetric; for example, the total number of lines of code. By default this information is sent to stdout, but a file can be specified with the -og switch.

The following switches control the gnatmetric output:

-x

Generate the XML output

-nt

Do not generate the output in text form (implies -x)

-d output_dir

Put textual files with detailed metrics into output_dir

-o file_suffix

Use file_suffix, instead of .metrix in the name of the output file.

-og file_name

Put global metrics into file_name

-ox file_name

Put the XML output into file_name (also implies -x)

-sfn

Use “short” source file names in the output. (The gnatmetric output includes the name(s) of the Ada source file(s) from which the metrics are computed. By default each name includes the absolute path. The -sfn switch causes gnatmetric to exclude all directory information from the file names that are output.)
