Jon, Right. They will be in collation order, not numerical order. It doesn’t work as a SWORD module for that reason and was my primary motivation for moving it to the Experimental repository. The tei2mod program needs to add support for Strong’s numbers as imp2ld has. It doesn’t pad the values as it puts them into the module. The ordering problem is a more general problem. Our collation order is good for ASCII. It is not good for Latin-1 as the byte value for accented letters is not adjacent to unaccented counterparts. Each language, script combination has its own collation order. Some languages use multiple glyphs for a single letter. This was noted earlier this month on this mailing list. In a past job, I had to implement a sort routine that would account for numbers occurring anywhere in a string. What I discovered in the process of doing this was that there is a need for an internal representation that differs from an external representation and routines that would normalize an external representation to an internal representation. Basically that routine would look at a string as an alternating sequence of numbers and non-numbers. The routine external2internal would create a string where numbers were zero padded to 10 digits. (It also did other things like strip noise words from the string, normalize dotted acronyms, normalize casing, …). Also in an earlier posting this month, I mentioned that ICU has collation routines that are language and script sensitive. The collation values that these produce are good for byte-order sorting, but are not intended for external use. What we need is a dictionary that stores the case-insensitive keys and that the frontend can collate as it sees fit. That collation order would be used to sort and show the case-insensitive keys. Basically another layer of indirection with a mapping from external presentation to the internal storage of the module. We’ve talked about this before. I think Troy suggested a mechanism. I’m going to survey the lexdict modules in all the repos in the Master list (and a few others) to see where we stand with those modules and the StrongsPadding flag. If any key starts with a number and isn’t zero padded, it will have difficulty if StrongsPadding=false is not in the conf. If a module has some that are zero padded and others that are not, this also is a problem. DM
