NAME

SYNOPSIS

DESCRIPTION

This man-page covers icmstart; refer to the icmbuild(1) man-page for information about how icmbuild can be used.

The icmstart script is a generic script that is used to initialize a directory with a basic set of files that are commonly used when developing a C++ or C program.

Icmstart creates an initial directory (here named `top-dir’) and installs the files CLASSES, VERSION and icmconf below top-dir. A second argument `program’ or `library’ may be specified as the default mode of operation of the icmbuild(1) script, usually resulting in adding additional skeleton source files. If the predefined set of files doesn’t fit your needs, then the default set can easily be modified. The default set of skeleton files is listed in the file /etc/icmake/icmstart.rc. Refer to the icmstart.rc(7) man-page for information about how this file is structured and how it can be adapted.

After switching to the directory created by icmstart icmbuild(1) may be used for program maintenance.

OPTIONS

o

-b
basic installation: the files VERSION, usage.cc and version.cc are not installed, and the #define USE_VERSION entry in icmconf is commented out;

o

-c confpath
use the configuration files (icmstart.rc, AUTHOR, YEARS and VERSION) if found in `confpath’ rather than using the files found in ~/.icmake and/or /etc/icmake/. Once a file is found it is used, allowing partial overrides of the default files provided by icmake(1);

o

-d
do not execute any commands, but show the commands that would have been executed on the standard output;

o

-I
do not install files;

o

-r
unconditionally replace existing files. If -r is not provided icmstart asks the user to confirm that an existing file must be overwritten. If a skeleton specification refers to a directory, the full directory and its subdirectories are replaced;

o

-s skeleton-path
by default skeleton files are listed in the skeleton resource file /usr/share/icmake/icmstart.rc. Alternatively, the skeleton resource file may be specified by the ICM environment variable, which -in turn- may be overruled by the path specified with the -s option. The skeleton path may be specified as a full file-path or as a directory, in which case the skeleton resource file is assumed to be icmstart.rc (see below at SKELETON FILES). Since icmstart uses cp to install files, cp must be available when icmstart should install skeleton files.

SKELETON FILES

The default resource specification file is /etc/icmake/icmstart.rc, containing:

    CLASSES
    icmconf
    P main.cc 
    P main.ih 
    P usage.cc
    P version.cc
    P ? scanner 
    P ? parser  
        

    cp -r /etc/icmake ~/.icmake
        

CONFIGURATION FILES

If the -c option was specified configuration files found in the path specified at this option are used. If not specified or if a file isn’t found then the path ~/icmake is inspected. If a configuration file isn’t found in ~/icmake either, configuration files in /etc/icmake are used.

Configuration files are optional; if absent icmstart can still be used, but in normal cases at least icmstart.rc is provided.

In addition to icstart.rc consider defining the files AUTHOR, VERSION, and YEARS in the configuration directory:

o

If the file AUTHOR exists it should have one line, defining the author of the program. E.g.,

    #define AUTHOR "Frank B. Brokken <f.b.brokken@rug.nl>"
        
    

If it does not exist icmstart uses the default:
#define AUTHOR "".

o

If the file VERSION exists it should have one line, defining the program’s version. E.g.,

    #define VERSION "1.00.00"
        
    

If it does not exist icmstart uses the default:
#define VERSION "0.01.00".

o

If the file YEARS exists it should have one line, defining the program’s initial release year or range of release years. E.g.,

    #define YEARS "2020"
        
    

or a range of years can be defined:

    #define YEARS "1992-2020"
        
    

If it does not exist icmstart uses the default:
#define YEARS "yyyy" where yyyy is the current year.

The AUTHOR, VERSION, and YEARS definitions are concatenated to one file, called VERSION, installed in the top-level directory.

If the file icmstart.rc does not exist (or is empty) icmstart merely installs the top-level directory, icmconf and VERSION.

FILES

o

/usr/share/icmake/icmconf Example of a icmbuild configuration file;

o

/usr/share/icmake/CLASSES Example of a icmbuild CLASSES file.

o

/etc/icmake/icmstart.rc Default skeleton resource file.
