Historical Deprecated40, Revision 2
Deprecated Items in 4.0
Include Files
This may sound drastic, but all include/*.e are deprecated. With 4.0 comes a newly organized standard library that is located in include/std. To use, you simply:
include std/sequence.e include std/datetime.e as dt include std/map.e as map
for example.
platform()
Platform has not been deprecated however it's use will slowly dwindle as we have a better construct now that does platform checks as well as conditional compilation. ifdef is superior to platform(). An example replacement of platform():
include misc.e if platform() = LINUX then puts(1, "Linux\n") elsif platform() = WIN32 then puts(1, "Windows\n") elsif platform() = DOS32 then puts(1, "DOS\n") else puts(1, "Unknown OS\n") end if
New code:
include misc.e ifdef LINUX then puts(1, "Linux\n") elsifdef WIN32 then puts(1, "Windows\n") elsifdef DOS32 then puts(1, "DOS\n") else puts(1, "Unknown OS\n") end ifdef
For all the benefits of ifdef please see the new 4.0 Manual.
db_fatal_id
This was made available by database.e in order to set the fatal error handler. If well behaved, it should present user with the error meaasge it got, clean up as much as possible and then abrt. But nothing was enforcing good behaviour.
Old code:
procedure db_handler(sequence error_msg) puts(2, error_msg) flush(db_current()) close(db_current()) abort(1) end procedure db_fatal_id = routine_id("db_handler")
New code:
procedure db_handler(sequence error_msg) puts(2, error_msg) flush(db_current()) close(db_current()) abort(1) end procedure include std/error.e crash_routine(routine_id("db_handler"))
