Hello, Sorry for the noise, but I didn't know where to post this. Please point me any place more appropriate for this kind of topic if you know one. So, I begin to play with Lua, trying to rewrite piece a software which take a digit ([0-9]*) in input, and provide a "how you spell/pronounce it" string in various languages in output. Well, that's not a transcendent goal, but I think it's a good way to learn this new tool. Now that I have a minimal piece of functions (but nothing close to even a single language decent support), I wanted to make a unit tests page. But I'm blocked, because I don't find how to call my main module within my test module. For those interested, pages are there : https://fr.wiktionary.org/wiki/Module:Pr0n https://fr.wiktionary.org/wiki/Module:Pr0n/test https://fr.wiktionary.org/wiki/Utilisateur:Psychoslave/test_pr0n And the relevant part are: pron = require( "Module:Pr0n" ) for i=0,99 do pron.ortho(i) -- fail! end Here is the error message: Erreur Lua dans Module:Pr0n à la ligne 37: attempt to index local 'frame' (a number value). Trace arrière: Module:Pr0n:37 : dans la fonction « ortho » Module:Pr0n/test:8 : dans la fonction « chunk » mw.lua:463 : dans la fonction « chunk » -- Association Culture-Libre http://www.culture-libre.org/
