NAME

        aegis new file - add new files to be created by a change

SYNOPSIS

        aegis -New_File file-name...  [ option...  ]
        aegis -New_File -List [ option...  ]
        aegis -New_File -Help

DESCRIPTION

        The aegis -New_File command is used to add new files to a change.  The
        named files will be added to the list of files in the change.

        For each file named, a new file is created in the development
        directory, if it does not exist already.  If the file already exists,
        it will not be altered.

        If you want a new source file to be executable (shell scripts, for
        example) then you simply use the normal chmod(1) command.  If any of
        the file's executable bits are set at aede(1) time the file is
        remembered as executable and all execute bits (minus the project's
        umask) will be set by subsequent aecp(1) commands.

        If you name a directory on the command line, the entire directory tree
        will be searched for new files.  (Note: absolutely everything will be
        added, including dot files and binary files, so you will need to clean
        out any junk first.)  Files below this named directory which are
        already in the change, or in the project, will be ignored.  The
        file_name_accept and file_name_reject patterns in the project
        aegis.conf file will also be applied, see aepconf(5) for more
        information.

   Directory Example
        There are times when a command such as
                $ aenf fubar/*
                aegis: project "example": change 42: "fubar/glorp" already in
                change
                aegis: project "example": change 42: found 1 fatal error, no
                new files added
                $
        will fail as shown.  There are several ways to deal with this, the
        easiest being to simply name the directory:
                $ aenf fubar
                aegis: project "example": change 42: file "fubar/smiley" added
                aegis: project "example": change 42: file "fubar/frownie"
                added
                $
        You could also use the find(1) command for arbitrarily complex file
        selection, but you must first exclude files that the above command
        excludes automatically:
                $ aelcf > exclude
                $ aelpf >> exclude
                $ find fubar -type f | \
                    grep -v -f exclude | \
                    xargs aegis --new-file -v
                aegis: project "example": change 42: file "fubar/smiley" added
                aegis: project "example": change 42: file "fubar/frownie"
                added
                $
        If you aren't using the exclude list, the find(1) command will need
        fine tuning for your development directory style.  If you are using
        the symlink-style, you will need to add the find -nlink 1 option in
        addition to the find -type f option.
                $ find fubar -type f -nlinks 1 | \
                    xargs aegis --new-file -v
                aegis: project "example": change 42: file "fubar/smiley" added
                aegis: project "example": change 42: file "fubar/frownie"
                added
                $
        If you are using the full-copy development directory style, you will
        have to use the exclude list method, above.

   File Templates
        When a new file is created in the development directory the project
        config file is searched for a template for the new file.  If a
        template is found, the new file will be initialized to the template,
        otherwise it will be created empty.  See aepconf(5) for more
        information.

        The simplest form is to use template files, such as
                file_template =
                [
                        {
                                pattern = [ "*.c" ];
                                body = "${read_file ${source template/c abs}}";
                        },
                        {
                                pattern = [ "test/*/.sh" ];
                                body = "${read_file ${source template/test abs}}";
                        },
                ];
        As you can see, the template files are part of the project source, so
        you can add the appropriate copyright notices, and wrappers, etc.  The
        $source substitution locates them, if they are not part of the current
        change (and they usually are not).

        The template files themselves contain substitutions.  The $filename
        substitution is available, and contains the name of the file being
        created.  This can be manipulated in various ways when constructing
        the appropriate file contents.  See aesub(5) for more information
        about substitutions.

        It is also possible to run a command to create the new file.  You can
        do this instead of specifying a body string, viz:
                file_template =
                [
                        {
                                pattern = [ "*" ];
                                body_command = "perl ${source template.pl abs} $filename";
                        },
                ];
        The command is run with a current directory set to the top of the
        development directory.  It is an error if the command fails to create
        the file.  You can mix-and-match the two techniques, body string and
        body_command, if you want.

   File Name Limitations
        There are a number of controls available to limit the form of project
        file names.  All of these controls may be found in the project
        configuration file, see aepconf(5) for more information.  The most
        significant are briefly described here:

        maximum_filename_length = integer;
                This field is used to limit the length of filenames.  All new
                files may not have path components longer than this.  Defaults
                to 255 if not set.  For maximum portability you should set
                this to 14.

        posix_filename_charset = boolean;
                This field may be used to limit the characters allowed in
                filenames to only those explicitly allowed by POSIX.  Defaults
                to false if not set, meaning whatever your operating system
                will tolerate, except white space and high-bit-on characters.
                For maximum portability you should set this to true.

        dos_filename_required = boolean;
                This field may be used to limit filenames so that they conform
                to the DOS 8+3 filename limits and to the DOS filename
                character set.  Defaults to false if not set.

        windows_filename_required = boolean;
                This field may be used to limit filenames so that they conform
                to the Windows98 and WindowsNT filename limits and character
                set.  Defaults to false if not set.

        shell_safe_filenames = boolean;
                This field may be used to limit filenames so that they do not
                contain shell special characters.  Defaults to true if not
                set.  If this field is set to false, you will need to use the
                ${quote} substitution around filenames in commands, to ensure
                that filenames containing shell special characters do not have
                unintended side effects.  Weird characters in filenames may
                also confuse your dependency maintenance tool.

        allow_white_space_in_filenames = boolean;
                This field may be used to allow white space characters in file
                names.  This will allow the following characters to appear in
                file names: backspace (BS, \b, 0x08), horizontal tab (HT, \t,
                0x09), new line (NL, \n, 0x0A), vertical tab (VT, \v, 0x0B),
                form feed (FF, \f, 0x0C), and carriage return (CR, \r, 0x0D).
                Defaults to false if not set.

                Note that this field does not override other file name
                filters.  It will be necessary to explicitly set shell_safe_-
                filenames = false as well.  It will be necessary to set dos_-
                filename_required = false (the default) as well.  It will be
                necessary to set posix_filename_charset = false (the default)
                as well.

                The user must take great care to use the ${quote} substitution
                around all file names in commands in the project
                configuration.  And even then, substitutions which expect a
                space separated list of file names will have undefined
                results.

        allow_non_ascii_filenames = boolean;
                This field may be used to allow file names with non-ascii-
                printable characters in them.  Usually this would mean a UTF8
                or international charset of some kind.  Defaults to false if
                not set.

                Note that this field does not override other file name
                filters.  It will be necessary to explicitly set shell_safe_-
                filenames = false as well.  It will be necessary to set dos_-
                filename_required = false (the default) as well.  It will be
                necessary to set posix_filename_charset = false (the default)
                as well.

        filename_pattern_accept = [ string ];
                This field is used to specify a list of patterns of acceptable
                filenames.  Defaults to "*" if not set.

        filename_pattern_reject = [ string ];
                This field is used to specify a list of patterns of
                unacceptable filenames.

        Please Note: Aegis also consults the underlying file system, to
        determine its notion of maximum file size.  Where the file system's
        maximum file size is less than maximum_filename_length, the filesystem
        wins.  This can happen, for example, when you are using the Linux
        UMSDOS file system, or when you have an NFS mounted an ancient V7
        filesystem.  Setting maximum_filename_length to 255 in these cases
        does not alter the fact that the underlying file systems limits are
        far smaller (12 and 14, respectively).

        If your development directories (or your whole project) is on
        filesystems with filename limitations, or a portion of the
        heterogeneous builds take place in such an environment, it helps to
        tell Aegis what they are (using the project config file's fields) so
        that you don't run into the situation where the project builds on the
        more permissive environments, but fails with mysterious errors in the
        more limited environments.

        If your development directories are routinely on a Linux UMSDOS
        filesystem, you would probably be better off setting
        dos_filename_required = true, and also changing the
        development_directory_template field.  Heterogeneous development with
        various Windows environments may also require this.

   File Name Interpretation
        The aegis program will attempt to determine the project file names
        from the file names given on the command line.  All file names are
        stored within aegis projects as relative to the root of the baseline
        directory tree.  The development directory and the integration
        directory are shadows of this baseline directory, and so these
        relative names apply here, too.  Files named on the command line are
        first converted to absolute paths if necessary.  They are then
        compared with the baseline path, the development directory path, and
        the integration directory path, to determine a baseline-relative name.
        It is an error if the file named is outside one of these directory
        trees.

        The -BAse_RElative option may be used to cause relative filenames to
        be interpreted as relative to the baseline path; absolute filenames
        will still be compared with the various paths in order to determine a
        baseline-relative name.

        The relative_filename_preference in the user configuration file may be
        used to modify this default behavior.  See aeuconf(5) for more
        information.

   Changing the Type of a File
        If you want to change the type of a file (say, from a test to a source
        file, or vice versa) you could do it as two changes, by first using
        aerm(1) in one change and then using aenf(1) or aent(1) in a second
        change, or you can combine both steps in the same change.  Remember to
        use the aerm -nowhiteout option or you will get a most peculiar new
        file template.

   File Action Adjustment
        When this command runs, it first checks the change files against the
        projects files.  If there are inconsistencies, the file actions will
        be adjusted as follows:

        create  If a file is being created, but another change set is
                integrated which also creates the file, the file action in the
                change set still being developed will be adjusted to "modify".

        modify  If a file is being modified, but another change set is
                integrated which removes the file, the file action in the
                change set still being developed will be adjusted to "create".

        remove  If a file is being removed, but another change set is
                integrated which removes the file, the file will be dropped
                from the change set still being developed.

   Notification
        The new_file_command in the project configuration file is run, if set.
        The project_file_command is also run, if set, and if there has been an
        integration recently.  See aepconf(5) for more information.

TEST CORRELATIONS

        The "aegis -Test -SUGgest" command may be used to have aegis suggest
        suitable regression tests for your change, based on the source files
        in your change.  This automatically focuses testing effort to relevant
        tests, reducing the number of regression tests necessary to be
        confident that you have not introduced a bug.

        The test correlations are generated by the "aegis -Integrate_Pass"
        command, which associates each test in the change with each source
        file in the change.  Thus, each source file accumulates a list of
        tests which have been associated with it in the past.  This is not as
        exact as code coverage analysis, but is a reasonable approximation in
        practice.

        The aecp(1) and aenf(1) commands are used to associate files with a
        change.  While they do not actively perform the association, these are
        the files used by aeipass(1) and aet(1) to determine which source
        files are associated with which tests.

   Test Correlation Accuracy
        Assuming that the testing correlations are accurate and that the tests
        are evenly distributed across the function space, there will be a less
        than 1/number chance that a relevant test has not been run by the
        "aegis -Test -SUGgest number" command.  A small amount of noise is
        added to the test weighting, so that unexpected things are sometimes
        tested, and the same tests are not run every time.

        Test correlation accuracy can be improved by ensuring that:

        o Each change should be strongly focused, with no gratuitous file
          inclusions.  This avoids spurious correlations.

        o Each item of new functionality should be added in an individual
          change, rather than several together.  This strongly correlates
          tests with functionality.

        o Each bug should be fixed in an individual change, rather than
          several together.  This strongly correlates tests with
          functionality.

        o Test correlations will be lost if files are moved.  This is because
          correlations are by name.

        The best way for tests to correlate accurately with source files is
        when a change contains a test and exactly those files relating to the
        functionality under test.  Too many spurious files will weaken the
        usefulness of the testing correlations.

OPTIONS

        The following options are understood

        -Build
                This option may be used to specify that the file is
                constructed during a build (often only an integrate build), so
                that history of it may be kept.  This is useful for generating
                patch files, where a history of generated files is important.
                Files created in this way may not be copied into a change,
                though they may be deleted.  Avoid using files of this type,
                if at all possible.

        -BAse_RElative
                This option may be used to cause relative filenames to be
                considered relative to the base of the source tree.  See
                aeuconf(5) for the corresponding user preference.

        -CUrrent_RElative
                This option may be used to cause relative filenames to be
                considered relative to the current directory.  This is usually
                the default.  See aeuconf(5) for the corresponding user
                preference.

        -Change number
                This option may be used to specify a particular change within
                a project.  See aegis(1) for a complete description of this
                option.

        -CONFIGured
                This option may be used to specify that the file is an Aegis
                project configuration file.  The default project configuration
                file is called aegis.conf, however any file name may be used.
                You may also use more than one file, splitting the content
                across several files, all of which must be of this type.

        -Help
                This option may be used to obtain more information about how
                to use the aegis program.

        -Keep
                This option may be used to retain files and/or directories
                usually deleted or replaced by the command.  Defaults to the
                user's delete_file_preference if not specified, see aeuconf(5)
                for more information.

        -No_Keep
                This option may be used to ensure that the files and/or
                directories are deleted or replaced by the command.  Defaults
                to the user's delete_file_preference if not specified, see
                aeuconf(5) for more information.

        -List
                This option may be used to obtain a list of suitable subjects
                for this command.  The list may be more general than expected.

        -Not_Logging
                This option may be used to disable the automatic logging of
                output and errors to a file.  This is often useful when
                several aegis commands are combined in a shell script.

        -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.

        -TEMplate
                This option may be used to specify that a new file template
                should be used, even if the file already exists.

        -No_TEMplate
                This option may be used to specify that a new file template
                should not be used, even if the file does not exist (any empty
                file will be created).

        -TERse
                This option may be used to cause listings to produce the bare
                minimum of information.  It is usually useful for shell
                scripts.

        -Verbose
                This option may be used to cause aegis to produce more output.
                By default aegis only produces output on errors.  When used
                with the -List option this option causes column headings to be
                added.

        -Wait   This option may be used to require Aegis commands to wait for
                access locks, if they cannot be obtained immediately.
                Defaults to the user's lock_wait_preference if not specified,
                see aeuconf(5) for more information.

        -No_Wait
                This option may be used to require Aegis commands to emit a
                fatal error if access locks cannot be obtained immediately.
                Defaults to the user's lock_wait_preference if not specified,
                see aeuconf(5) for more information.

        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
        aegis are long, this means ignoring the extra leading '-'.  The
        "--option=value" convention is also understood.

RECOMMENDED ALIAS

        The recommended alias for this command is
        csh%    alias aenf 'aegis -nf \!* -v'
        sh$     aenf(){aegis -nf "$@" -v}

ERRORS

        It is an error if the change is not in the being developed state.
        It is an error if the change is not assigned to the current user.
        It is an error if the file is already part of the change.
        It is an error if the file is already part of the baseline.
        It is an error if the files named on the command line are not normal
        files and not directories.  (If you need symbolic links or special
        files, create them at build time.)
