And how can one create building instructions without access to a *nix
machine (what is that anyway :-) and no cygwin components on a Windows PC?

Well, that’s what LPub does, right?
|
LOL! I know (ofcourse). I wrote it wrong. I ment: how can one use the script
Travis provided to insert the PreL3P codes into the LDraw files :-)

Try the following (assumes Win2K/WinXP):
- Download cygwin from http://www.cygwin.com/ (click the “Install or update now!” link)
- Run cygwin’s setup.exe file that you downloaded
- Follow the instructions for a default install and choose a working mirror. (I used mirror.rhsmith.umd.edu after much trial and error.)
- Start->Run: cmd
- Note the directory that you’re in, and explore to there in Windows Explorer
- Create a file named StepFade.sh (or whatever you want to call the script) in that directory, and paste the contents of my script text into that file. Modify the bits that I said to modify to suit your setup
- Start->All Programs->Cygwin->Cygwin Bash Shell
- Change into the directory containing your step files using the cd command. Note that cygwin is very strange with paths, so instead of C:, you use /cygdrive/c. Also, instead of \ (back slash) in paths, you use / (forward slash). So to go to C:\ldraw\models\TestModel, you would type the following:
cd /cygdrive/c/ldraw/models/TestModel
|
|
- (Replace Model above with the base filename of your model.)
Let me know if you have any questions or problems.
Some notes about the above:
- The directory you start out in when you run cmd is your USERPROFILE directory in Windows. In cygwin, this is considered to be your home directory.
- In the bash shell (and all other unix shells), ~ maps to your home directory, so ~/StepFade.sh tells it to run the StepFade.sh script that’s located in your home directory. That’s why I had you place the script there. Alternatively, you can place it in C:\cygwin\usr\local\bin, and it will be in the path in cygwin, allowing you to just run it. (This assumes that you install cygwin into the C:\cygwin directory. If you put it elsewhere, adjust accordingly.)

Or if you’re really, really scared of cygwin, this StepFade.bat file might
work on XP. But I didn’t test it all that much, and I don’t claim to know
all the nuances of the old DOS fc and find commands. The unix diff and
grep commands are so much easier to use.
