You can define a trigger that fires correctly depending on the type of platform on which it runs (Linux®, the UNIX system, and Windows® computers). The following techniques are available:

With one technique, you use different paths or different scripts; with the other technique, you use the same script for all platforms. You can also share triggers; see Tips for sharing scripts.

You can also share scripts; see Sharing triggers among different types of platform.

To define a trigger that fires on Linux and the UNIX system; the Windows system; or both types of platform, and that uses different paths to point to the trigger scripts, use the mktrtype command with the –execunix and –execwin options. These options behave the same as –exec when the trigger fires on the appropriate platform (Linux and the UNIX system for –execunix or the Windows system for –execwin). On the inappropriate type of platform, the related script does not run.

This technique allows a single trigger type to use different paths for the scripts or to use completely different scripts on Linux or the UNIX system and the Windows computer. For example:

cleartool mktrtype –element –all –nc –preop checkin 
–execunix /public/scripts/precheckin.sh 
–execwin \\neon\scripts\precheckin.bat  
pre_ci_trig

Tip: The command line example is broken across lines to make the example easier to read. You must enter the command on one line.

On Linux or the UNIX system, only the script precheckin.sh runs. On the Windows system, only precheckin.bat runs.

To prevent users on a new platform from bypassing the trigger process, triggers that specify only –execunix always fail on the Windows system. Likewise, triggers that specify only –execwin fail on Linux and the UNIX system.

To use the same trigger script on Linux, the UNIX system, and the Windows system, use a batch command interpreter that runs on all operating systems. For this purpose, the ratlperl program is included in the HCL VersionVault configuration. You can use this version of Perl on the Windows system, Linux, and the UNIX system. The commands Perl on Linux and the UNIX system and ccperl on the Windows system are wrapper programs that run ratlperl.

The following mktrtype command creates sample trigger type pre_ci_trig and names precheckin.pl as the executable trigger script.

cleartool mktrtype –element –all –nc –preop checkin  \
–execunix 'Perl /public/scripts/precheckin.pl' \ 
–execwin 'ccperl \\neon\scripts\precheckin.pl' \ 
pre_ci_trig

Note: In your scripts, you can run ratlperl directly. Ensure that you include the following default paths to execute the scripts successfully:

On Linux and the UNIX system: /opt/hcl/ccm/common/bin
On the Windows system: <install_location>\HCL\Common\

The value install_location is the root folder in which you installed HCL VersionVault.
