NAME

       aegis make transparent - make branch file transparent

SYNOPSIS

       aegis -Make_Transparent [ option...  ] filename...
       aegis -List [ option...  ]
       aegis -Help
       aegis -VERSion

DESCRIPTION

       The aegis -Make_Transparent command is used to add a file to the change
       which will result in the named file being made transparent in the
       branch when the change is integrated.  The version of the project file
       from the deeper branch will then show through.

       You may name a directory to make all files in that directory tree
       transparent.  It is an error if there are no relevant files.

   Branch vs Change
       The aecpu(1) command may only be applied to a change.  If you wish to
       perform the same operation on a branch, use the aemt(1) command,
       through the agency of a change.

   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.

   Process Side Effects
       This command will cancel any build or test registrations, because
       changing the change file list logically invalidates them.

   Notification
       The make_transparent_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.

OPTIONS

       The following options are understood:

       -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.

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

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

       -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.

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

       -UNChanged
               Examine the named files to see if they are unchanged.  Only
               remove the unchanged files from the branch, and leave the files
               which have changed.  If no files are named on the command line
               all branch files are checked.

       -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 aemt ’aegis -mt \!* -v’
       sh$     aemt(){aegis -mt "$@" -v}

       This command is dedicated to my wife, Mary-Therese.  When I was trying
       to explain what this command did, she said "I had one of those on my
       bicycle when I was young, but it fell off".

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 not present in the immediate branch.
       It is an error if the file is present in the immediate branch, but is
       not also present in a deeper branch.
       It is an error if the file is only present in the trunk branch.

EXIT STATUS

       The aegis command will exit with a status of 1 on any error.  The aegis
       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.
