Re: [Gpsbabel-misc] Setting temp path without Windows environmental variable

[Robert L. <rob...@gp...>]

Hi, Phillip and welcome.

You're right. The code gets the temporary directory from the OS, but then
doesn't use QTemporaryFile <http://doc.qt.io/qt-5/qtemporaryfile.html> to
ensure that the file within it is unique. I can't dive into the code right
now, but it's just so hokey that that format alone (I think) writes a file
while you're reading.

If you're automating this, I'd think that scripting this in a batch file
would look something like
mkdir temp/1 temp/2 temp/3
    set TMP=C:\temp\1\ && gpsbabel.exe -w -t -i mtk -f COM6 -o gpx1 -F
test.gpx
    set TMP=C:\temp\*2*\ && gpsbabel.exe -w -t -i mtk -f COM7 -o *gpx2* -F
test.gpx
    set TMP=C:\temp\*3*\ && gpsbabel.exe -w -t -i mtk -f COM8 -o *gpx3* -F
test.gpx
...but that does them one at a time and I'm guessing the real goal is to do
them at the same time. Again, making this up because I'm not a windows dev,
bug I can read stack overflow...
    start cmd /c call set TMP=C:\temp\1\ && gpsbabel.exe -w -t -i mtk -f
COM6 -o gpx1 -F test.gpx
    start cmd /c set TMP=C:\temp\*2*\ && gpsbabel.exe -w -t -i mtk -f COM7
-o *gpx2* -F test.gpx
    start cmd /c set TMP=C:\temp\*3*\ && gpsbabel.exe -w -t -i mtk -f COM8
-o *gpx3* -F test.gpx

but there may be some quoting rules that I'm breaking. Start with something
like
https://stackoverflow.com/questions/649634/how-do-i-run-a-bat-file-in-the-background-from-another-bat-file

Really, this code just needs to be fixed to Not Do This. Any takers?
