1. Searching for paths
- Posted by bensler at mail.com
Feb 25, 2002
Hi all,
I need to determine the Euphoria directory, and the Windows directory.
I can use get_env() to get %EUDIR and %WINDIR.
What if one/both of those don't exist?
I can do a walk_dir() search for ex.exe and win.exe(com?), but is that
sufficient? Any one computer can have more than one copy of both EU and
Windows. What if the file I'm looking for has been renamed?
How can I guarantee that I have found the right directories?
Would I find win.exe on >win98 ?
My plan so far is to check the environment variables, if I can't find
them, then I walk_dir() starting from C:\ looking for ex.exe, even if I
find it, continue searching to determine if there is a second copy.
If I find a second copy, then I can't verify the Euphoria directory, and
the user must be prompted for it.
Same for WINDIR. I could see this being pretty slow though.
Maybe I'm just trying too hard to automate it.
My second plan is to just search for the specific directory if the
environment variable doesn't exist. Can't find %EUDIR variable, then
check if C:\Euphoria exists, if not, prompt the user.
Also, is there a simple DOS way of determining the drive letters
available? So I can walk the drives as well.
Thanx
Chris

I suggest that Euphoria have a link in the registry to indicate where on
what disk it can be found. Maybe the new Euphoria installer could do this.

Chris,
are you trying to find out if Euphoria is installed or not?
If you are, then you might like to look at the directories in the PATH
symbol, looking for ex.exe *and* exw.exe in the same directory. Unless the
user has done some serious rearranging of the Euphoria directory structure,
you should find ex.exe in a EUPHORIA\BIN directory somewhere on the path.

For windows directory you can use this function...
function ambilwindir() = your windows directory
object ambilwindir_kernel32
ambilwindir_kernel32 = open_dll("kernel32.dll")
object ambilwindir_GetWindowsDirectory
ambilwindir_GetWindowsDirectory = define_c_func(ambilwindir_kernel32,
"GetWindowsDirectoryA", {C_POINTER, C_LONG}, C_LONG)
global function ambilwindir()
object hasil, len
hasil = allocate_string(repeat(0,254))
len = c_func(ambilwindir_GetWindowsDirectory, {hasil, 255})
return peek({hasil, len})
end function

I don't know what you mean by ACTIVELY installed. Is this different to
INACTIVELY installed? If so, I would have thought that the active Euphoria
was the one that was on the PATH. That's why I said to scan the directories
in the PATH for ex.exe. If however, ACTIVE means "on disk" then just scan
every directory.
Also, what do you mean by "continue to search for ex.exe even after finding
it". If you've found it, why would you continue to search for it? Or do mean
you need to find all files that have the name "ex.exe"?

6. Re: Searching for paths
For finding what drives are on a system, Al Getz has some code in the
archives:
http://www.rapideuphoria.com/getdrive.zip
it's written as a windows program, but the drive functions can easily be
abstracted; it gives *all* drives on system, but you can also easily make
it just return hard disk drives.
Does say "--requires Windows 95 OEM Service Release 2 (OSR2) or above.", so
it might not work on all systems?
