| I have a plugin that uses <include> to include other files with scripting in them.
The problem is that when a recent action sets the path AWAY from the path your plugin is, (re)loading it will give errors since it cannot find the files. The plugin will, however, appear in Plugins as if it had been loaded.
Example situations in which this happens:
* Opening a worldfile that is in another directory than said plugin. I get spammed with errors (I include like 20 files across a few plugins).
* Opening another plugin in another directory through Plugins>Add, and trying to reload said plugin.
Temporary fix:
1) Try to go to Plugins>Add, and load the file again. It will error, saying something with that id was already loaded.
2) Click Reinstall. It will work now, because apparently the path has been changed. | | Top |

| See this recent post:

I can see this is a bit of an ongoing problem, reluctant as I am to fiddle with the "current directory" it might be necessary.
The scenario you describe, by invoking the standard file dialog box, changes the current directory back to where you want it.

| I hadn't seen that post although I did search, I'm sorry. But it wouldn't be an option for me for two reasons:
1) I use Python, not Lua.
2) I recall to have read that ImportXML imports into the global namespace, which would effectively break my plugin (unless I'd add a lot of checks on the plugin-id, which would nullify the use of <include> in the first place).
The problem is at load time, right? I am not sure where this code is interpreted (mush or some other library), but maybe relative paths starting with ./ can, by default, be substituted with the path the plugin is in?
Examples. World file is C:\Program Files\MUSHClient\worlds\Test.mcl. Plugin that calls it would be D:\Curing\Main.xml:
<include name="$MUSHCLIENT$\worlds\plugins\Python.pys" /> -- would load C:\Program Files\MUSHClient\worlds\plugins\Python.pys (so default modules and files can be loaded)
<include name="Herbs.xml" /> -- would load C:\Program Files\MUSHClient\worlds\Herbs.xml (so current behaviour with working directory wouldn't break)
<include name="./Vials.xml" /> -- would load D:\Curing\Vials.xml
<include name="C:\Salves.xml" /> -- would load C:\Salves.xml
Would that be possible? | | Top |

| ImportXML imports into the namespace of whatever plugin it is called from (or the main namespace). I tested that when doing my earlier suggestion.
However I take your point about the problem with it not being Lua.
However any language that is able to open a file could then read it in and call ImportXML.
I will look at temporarily changing the working directory during loading a plugin. |

| Great. :D
The thing about ImportXML must have been an older bug that has been squashed since. I come here more often, hehe. :D
Is there a reason why my suggestion isn't possible though? I think manually parsing would be preferable over playing with the current directory to fit moods and grudges with the (re)loading of plugins. | | Top |

| Sure, good idea.
In version 3.76 you will be able to use the following special strings inside the include directive:
- $PLUGINSDEFAULTDIR - default directory for plugins
- $PROGRAMDIR - directory MUSHclient executable is in
- $WORLDDIR - directory current world is in
- $PLUGINDIR - directory current plugin is in
You should be able to use these to make plugins load relative to themselves, eg.
<include name="$PLUGINDIR\myincludes.xml" />

| This seems to be a bit of an ongoing problem, so version 3.80 adds a function ChangeDir - this lets you change the working directory to a known value.
Thus, before loading a plugin's extra files (eg. with the Lua "require" statement) you could change the working directory to that which contains the plugin first. |
