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
