Convert .txi files in the Octave source into an INDEX structure
suitable for generating a functon reference.
file_pattern must be a string containing either the name of a .txi
file, or a pattern for globbing a set of files (e.g. "*.txi"). The resulting
cell array index contains a set of structures corresponding to those
generated by pkg ("describe"). These structures can then be given to
generate_package_html to produce HTML content.
As an example, if the Octave source code is located in ~/octave_code, then this function can be called with
octave_source_code = "~/octave_code"; index = txi2index (fullfile (octave_source_code, "doc/interpreter", "*.txi"));
