NestedQuotedString

Nested quoted string

If your add-on produce error on loading stage and it looks like quote below, then you can find solution to your problem here.

 Nested quoted string
 at core/macros/image-utils.cfg:28 
 included from ai/ais/ai_default_rca_strong.cfg:2
 included from _main.cfg:30
 included from ~add-ons/Add-on_Name/scenarios/01_Scenario.cfg:62
 included from ~add-ons/Add-on_Name/_main.cfg:36

This error message consist of three parts:

Error name.. In this case it is "Nested quoted string".
(upper) list of mainline files, which are core of Battle for Wesnoth
(lower) list of your add-on files. Their names are usually started from "~add-ons/Add-on_Name", where Add-on_Name is the name of folder, which contains your add-on codebase.

Source of the error is some string, which misses double quote sign at the end.

For example:

 caption = _"Welcome to Wesnoth!
 speaker = narrator

There is no double quote sign in the end of caption value. In other example, "message" key contains multi-string value and lacks double quote sign too:

 message = _"For this tutorial, you are playing Konrad.
 You are standing in the keep, and your mentor Delfador is on the east side of the river.
 speaker = narrator

To find source of the error, you need to check listed files from upper one to lower one. If you hadn't modified core files by yourself, then you can skip all mainline files listed in second part of the error message. Your add-on are started from: ~add-ons/Add-on_Name/scenarios/01_Scenario.cfg and ends with ~add-ons/Add-on_Name/_main.cfg

In each file, go to line, which number is written after name of the file. For ~add-ons/Add-on_Name/scenarios/01_Scenario.cfg you need to go to line 62. Then start looking upwards. If you haven't found the source of the problem in this file, then check next file in similar manner.

To fix this error you need to add closing qoute for string, which produce the problem. For first example in this tutorial it will look like:

 caption= _"Welcome to Wesnoth!"
 speaker = narrator

Pay attention to the closing quote in the end of the string.

 message = _"For this tutorial, you are playing Konrad.
 You are standing in the keep, and your mentor Delfador is on the east side of the river."
 speaker = narrator

Closing quote should be on the end of second string. If you add double quote at the end of the first string of "message" value, then you produce other error.
