DESCRIPTION

This module provides some utility functions which are useful when working with SICI.

None of them are exported by default.

FUNCTIONS

STRING titleCode_from_title( STRING )

Tries to derive the titleCode (cf. the contribution segment) from a string (i.e.: the title of the contribution) passed to it.

Since the rules for the construction of the titleCode are quite complex, this method probably won´t generate the correct code if the title contains elements other than regular english words (like mathematical or chemical symbols or characters from a non-ascii alphabet).

If the method is able to generate a code it will be returned. Otherwise the return value is undef.

In order to have a better chance of generating a standard-conformant code the modules Text::Unidecode and Text::Undiacritic are required. If they cannot be found, warnings are emitted but a code might nonetheless be generated. However, if the title is in a language other than english, the probability of generating the correct code sinks even more.

STRING calculate_check_char( STRING )

Calculates and returns the check character. Does not check, if the string param is a valid SICI!

A check character already present in the passed-in SICI will simply be ignored.
