Dear Daniel
i have been rewriting all the native configuration we have for a proxy to
kemi lua and i'm (i think) having it working fine, but i'm still missing
some functions to be migrated, some of those are not even working with
KSR.x.modf
Now i'm using version: kamailio 5.4.0-dev2 (x86_64/linux) f268aa
-be able to select facility on KSR.xlog, equivalent to xlog("LOG_LOCAL7",
"L_NOTICE", "$var(x)");
-sipt module functions
-dialog dlg_set_ruri function (maybe some others), this is now even working
with modf (ERROR: app_lua [app_lua_api.c:1633]: sr_kemi_lua_modf():
function 'dlg_set_ruri' is not available)
-tm t_relay_to_tcp
if you have any update about this function exportation, it would be great
best regards
david

And the functions for dialog vars are in latest
master branch, -dev5 is a
bit older, last one has -dev6. Fetch latest master branch and try again.

Hello,
in short, all functions exported to native kamailio.cfg will be exported
to KEMI if they don't have an (native) alternative in those scripting
languages. If some are missing, that's because nobody did it so far for
specific modules and maybe I missed some functions for modules that already
have some exports to KEMI.
Those from sdpops likely I missed them, I will export them. Then I am
not sure why sipt was skipped, should be exported as well -- if nobody does
it, I will do it sometime soon. For call_obj I already saw commits pushed
to master. Variants of xlog functions could be missing, because was one of
the first modules exported to KEMI, but with the commonly used (at least by
me) functions, needed for testing, then probably I didn't approach again
the module.
Regarding the header operations, the remove, insert and append are
exported via KSR.hdr submodule, not KSR.textops. It was how Lua had it in
the previous version and when I started with KEMI, I worked on old lua
module code. Maybe confusing a bit, anyhow the docs are at:

hello all
we are trying to rewrite our code to lua kemi, and we have found some
issues/questions until we would like to share with you.
-module call_obj not exported, we have tested a patch for the module to
export the functions to kemi, which seems works fine
-KSR.xlog.xinfo seems not able to select a facility as we currently can
like xlog("LOG_LOCAL7", "L_NOTICE", "$var(xxxx)");
-module sipt not exported yet, must use ksr.x.modf ? will be exported
for a future version?
-on 5.3.0-dev5 we don't see the KSR.dialog.var_sets() and
KSR.dialog.var_get/e/w() functions in the code, so we do use KSR.pv
functions to set and retrieve those dialog vars. However i see them on
master branch. Which kamailio release would have them?
-sdpops function sdp_with_codecs_by_name seems to not me exported, is
it on a todo list?
-textops module, missing remove_hf and append_hf functions exported. We
already did a patch for the remove_hf, despite we could work with textopsx
remove_hf_value function to get the almost the same functionality.
However, with append_hf i'm having some more issues.
We cannot use modf to exec those funtions, we get something like
For ---> KSR.x.modf("append_hf", "User-Agent: test",
"To");
I get something like ----> Jun 27 07:19:16 proxy-1
/usr/local/kamailio/sbin/kamailio[5525]: ERROR: app_lua [app_lua_sr.c:188]:
lua_sr_modf(): function 'append_hf' has fixup - cannot be used
I could append a new header and not only at the end of the message by
replacing a header called the same way, by doing something like
KSR.textopsx.insert_hf_value("header", "value");
KSR.textopsx.remove_hf_value("header[-1]");
but i'm not able to insert a header after another different one like we
can do with append_hf("header:value", "To") for instance.
Is it expected to have it on a next commit those append_hf and
remove_hf exported.
Would we do a pull request with the ki_remove_hf we already have and
the call_obj functions too? We can check to export append_hf too if it's
not planned to be done
thanks a lot and regards
david
