Hello First I don't know if this is the correct list, so please point me further if it isn't. I noticed that the shared-mime-info contained this entry for the Ada95 programming language: <mime-type type="text/x-adasrc"> <comment>Ada source code</comment> <comment xml:lang="de">Ada-Quelltext</comment> <comment xml:lang="el">??????? ??????? Ada</comment> <comment xml:lang="fi">Ada-l?hdekoodi</comment> <comment xml:lang="no">Ada-kildekode</comment> <glob pattern="*.adb"/> <glob pattern="*.ads"/> </mime-type> This is a bit ackward. It would be like saying: <mime-type type="text/x-csrc"> <comment>C source code</comment> <glob pattern="*.c"/> <glob pattern="*.h"/> </mime-type> as .ads are the spec files of Ada (to some extent like .h for C). To summarise the extensions used by GNAT: .ads Spec file (containing the declarations) .adb Body file (containing the code) .ali Ada Library info (which contains additional information used to check that an Ada program is consistent. This is made when you compile a program) .adt Ada Tree (A tree file stores a snapshot of the compiler internal data structures in the very end of a successful compilation. It contains all the syntactical and semantic information about the unit being compiled and all the units upon which it depends semantically. Some tools need tree files to obtain this information.) .ada Contains both Spec and Body (used by other compilers too) So it would be nice if the freedesktop mime file could be updated to the following for Ada: <mime-type type="text/x-adasrc"> <comment>Ada source code</comment> <comment xml:lang="de">Ada-Quelltext</comment> <comment xml:lang="el">??????? ??????? Ada</comment> <comment xml:lang="fi">Ada-l?hdekoodi</comment> <comment xml:lang="no">Ada-kildekode</comment> <glob pattern="*.adb"/> <glob pattern="*.ada"/> </mime-type> <mime-type type="text/x-adaspec"> <comment>Ada source code spec</comment> <comment xml:lang="no">Ada-kildekodespesifikasjon</comment> <glob pattern="*.ads"/> </mime-type> <mime-type type="text/x-adalibinfo"> <comment>Ada library information</comment> <comment xml:lang="no">Ada-bibliotektinformasjon</comment> <glob pattern="*.ali"/> </mime-type> <mime-type type="text/x-adatree"> <comment>Ada tree</comment> <comment xml:lang="no">Ada-tre</comment> <glob pattern="*.adt"/> </mime-type> Regards, Preben Randhol Reference: <URL: http://gcc.gnu.org/onlinedocs/gcc-4.0.0/gnat_ugn_unw/File-Naming-Rules.html#File-Naming-Rules> <URL: http://gcc.gnu.org/onlinedocs/gcc-4.0.0/gnat_ugn_unw/The-Ada-Library-Information-Files.html#The-Ada-Library-Information-Files> <URL: http://lgl.epfl.ch/teaching/programming01_02/doc/gnat_ug.html#SEC142>
