Detect LDraw Installation Path about ldr-importer HOT 6 CLOSED

The only potential annoyance I see with this is that it is quite simple to install ldraw in whatever directory you want (EG: C:\Users\MYACCOUNT\My Videos\Lego\Random Stuff\ldraw,) I believe even on Windows, so some people might prefer that you:

1. Try to auto detect as above,
2. Save presets to a configuration file
3. Load presets after trying to auto detect (if they exist) and auto-select one instead.

Ah, but what kind of configuration file? Thanks to @Banbury, we can save our installation path using the Blender present option, but they cannot be automatically loaded without a long custom process, it seems.

Am I wee bit confused on step 3.

Hmm.
I've never worked on blender addons before, but my project TitleTool (runs blend files with python scripts) makes use of configuration files. Theres a little trick you can use to write an actual python file, then execute the code in it anywhere in the script as part of the script (kind of like a PHP include). Its kind of dirty and probably frowned upon, but it works quite well.

Clarification on step 3:

1. Check configuration file for user-set path
2. If user-set path exists, attempt to locate ldraw using it.
3. If ldraw is not found, auto-detect. If auto-detect fails, set to default
4. If ldraw is found, use user-set path

Where is the code for the configuration files? I'll take a look at it. I was actually about to begin working on the process when I got an email with your comment.

That makes sense. Will attempt to do.

First, use whatever you want to write a vaild python file, eg (file config.py):

userSelectedLdrawDir = "~/Software/ldraw"

Then in your addon file: write

filename = os.getcwd()+"/config.py"
exec(compile(open(filename).read(), filename, 'exec'))
print(userSelectedLdrawDir)

That's How I interfaced TitleTool's Java program, and the Python blender bootstrap.

Like I said, quick and dirty, basically equivalent to doing a

from config import *

but with more control over the directory location.
