Yes, if you subdivide. I organized them by one category: generally useful features (which can be used by many other libraries). > We sadly don't have a good place to put such generic functions. > Maybe we could create a new "set" library of set functions > (union, intersection, difference, powerset, membership, negation, ...). And some other suggestions (I did not think too much): * A list library (to provide something subr.el and cl-lib missed) * A string manipulation library * A math library (maybe Calc is enough?) * A hash library (implements a common interface to different secure hash algorithms.) * A time access and conversion library * A logging facility library * The long lost concurrency and FFI libraries * An I18N library [OT] And some not-so-general suggestions: * Interface to the DBM database * Interface to the SQLite database (like this one: http://www.emacswiki.org/emacs/sqlite.el) * A CSV file reading and writing library (maybe csv-mode from GNU ELPA is a good choice) * A JSON encoder and decoder * Access to the POSIX locale database and functionality. -- Best regards, Xue Fuqiao. http://www.gnu.org/software/emacs/
