Vortex Module Creation

A new revision of a library module is created by checking it in with the following command-line syntax:

texis -ci [-module name] [-log msg] [-force] [-lock|-unlock] script

The -ci option indicates check-in. The module will have the given name by which it is known to other scripts; if not specified it defaults to the base filename of the script. Its source code is taken from the script file. A log message describing the changes made can optionally be given with the -log message; if not specified the user is prompted for a message.

If the module already exists in the library, the last revision must be locked by the same remote host for check-in to occur. This helps ensure that only one programmer is working on the module at a time, so that changes are "serial" and seen by all. (The -force option can be given to override this check and force check-in regardless; the -CI combines -ci and -force.) A successful check-in unlocks the module by default; the lock can be maintained by giving the -lock option.

A new revision of the module with an incrementing version number is deposited. Any scripts that are known to use this module are flagged for re-compilation. In this way a script can be sure of always using the latest version of a module, without having to manually re-compile the script each time.

Note that a specific revision of a module is never modified once checked in: when the module is changed, a new revision is deposited. This preserves old versions in case functionality issues or bugs arise and a previous version is needed. Once checked in, a revision's source file can be deleted if desired, as the source is stored in the library.
