aemeasure

NAME

aemeasure - simple file metrics

SYNOPSIS

aemeasure [ infile [ outfile ]]

DESCRIPTION

The aemeasure command is used to measure a few very simple file statistics: lines of code, lines of comments, blank lines. It is an example of a probgram which produces its output in the aemetrics(5) format, suitable for Aegis to read and understand as file metrics.

The language of the file is determined by examining the file suffix.

.c, .h, .y	C language
.cc, .CC, .c++,	C++ language
.man, .mm, .ms, .so	GNU Groff input

METRICS

Aegis is capable of recording metrics as part of the file attributes of a change. This allows various properties of files to be recorded for later trend analysis, or other uses.

The specific metrics are not dictated by Aegis. It is expected that the integration build will create a metrics file for each of the source files the change. These metrics files must be in the format specified by aemetrics(5).

The name of the metrics file defaults to "filename,S", however it may be varied, by setting the metrics_filename_pattern field of the project config file. See aepconf(5) for more information.

If such a metrics file exists, for each source file in a change, it will be read and remembered at integrate pass time. If it does not exist, Aegis assumes there are no relevant metrics for that file, and proceeds silently; it is not an error.

OPTIONS

The following option is understood

-LANGuage name

This option may be used to specify the input language of the file, rather than have the input language be guessed fromn the file suffix. The name must be one of the following: C, C++, roff or generic. Any other name will result in an error.

See also aemeasure(1) for options common to all aemeasure 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 aemeasure are long, this means ignoring the extra leading '-'. The "--option=value" convention is also understood.

EXIT STATUS

The aemeasure command will exit with a status of 1 on any error. The aemeasure command will only exit with a status of 0 if there are no errors.

ENVIRONMENT VARIABLES

See aegis(1) for a list of environment variables which may affect this command. See aepconf(5) for the project configuration file's project_specific field for how to set environment variables for all commands executed by Aegis.
