answer = mstrrep( txt , search , replace , overlap )
Returns the string answer obtained modifying a given string txt by replacing all the occurrences of the substring search with the content of replace .
txt ::row_string:: text to be transformed search ::row_string:: substring to search for replace ::row_string:: substring to replace with overlap ::binary:: flag indicating whether or not overlapped occurrences of the search string are allowed This function extends and disambiguates the strrep(.) function of the standard library, enabling the explicit choice between the two behaviours that are currently implemented in different computing environments: if the overlap flag is set to a true value, even overlapped occurrences of the search string are searched for and replaced. Otherwise, overlapped matches are ignored. The overlap input argument has not a default value in order to avoid unexpected behaviours in some computing environments. Please prefer this function instead of the pre-defined strrep(.), when the portability cost is higher than the computational cost.

The Mastrave modelling library is committed to provide reusable and general - but also robust and scalable - modules for research modellers dealing with computational science. You can help the Mastrave project by providing feedbacks on unexpected behaviours of this module. Despite all efforts, all of us - either developers or users - (should) know that errors are unavoidable. However, the free software paradigm successfully highlights that scientific knowledge freedom also implies an impressive opportunity for collectively evolve the tools and ideas upon which our daily work is based. Reporting a problem that you found using Mastrave may help the developer team to find a possible bug. Please, be aware that Mastrave is entirely based on voluntary efforts: in order for your help to be as effective as possible, please read carefully the section on reporting problems. Thank you for your collaboration.
