@ -109,6 +109,21 @@ In general, importing a dynamic library does not require any special linker
options or linking with import libraries. This also implies that no *devel*
packages need to be installed.
The ``dynlib`` import mechanism supports a versioning scheme:
.. code-block:: nimrod
proc Tcl_Eval(interp: pTcl_Interp, script: cstring): int {.cdecl,
importc, dynlib: "libtcl(8.5|8.4|8.3).so.(1|0)".}
At runtime the dynamic library is searched for (in this order)::
libtcl8.5.so.1
libtcl8.4.so.1
libtcl8.3.so.1
libtcl8.5.so.0
libtcl8.4.so.0
libtcl8.3.so.0

The ``--dead_code_elim:on`` command line switch has the same effect as marking
any module with ``{.dead_code_elim:on}``. However, for some modules such as
every module with ``{.dead_code_elim:on}``. However, for some modules such as
the GTK wrapper it makes sense to *always* turn on dead code elimination -
no matter if it is globally active or not.

Disabling certain messages
--------------------------
Nimrod generates some warnings and hints ("line too long") that may annoy the
user. Thus a mechanism for disabling certain messages is provided: Each hint
user. A mechanism for disabling certain messages is provided: Each hint
and warning message contains a symbol in brackets. This is the message's
identifier that can be used to enable or disable it:

String case statements are optimized too. A hashing scheme is used for them
if several different string constants are used. This is likely to be more
efficient than any hand-coded scheme.
