gcov7-viewer's Issues

Accidental Install, Uninstall Failed

I accidentally installed this tool, but upon uninstalling, Gcov Viewer just throws errors:

Error while trying to run gcov, try to change the "Gcov Binary" setting. Error: Command failed: /home/tentorm/.vscode-server/extensions/bigforce.gcov7-viewer-0.0.5/gcov7-json.py --help /bin/sh: 1: /home/tentorm/.vscode-server/extensions/bigforce.gcov7-viewer-0.0.5/gcov7-json.py: not found

I've tried deleting the .vscode-server/extension/bigforce.gcov7-viewer-0.0.5 folder, but there was no improvement.

EDIT: was able to fix it by reinstalling gcc and purging the entire vscode-server folder after a reboot

support older gcov versions (-x -> -p -> none)

gcov 7 introduced --hash-filenames (which is used as -x in the script).
gcovr checks once if this option is available (peeking into gcov's help), if it isn't then --preserve-paths (-p) is used instead (actually gcovr also checks for this option in the help and if it isn't available it uses neither of them and output a warning).

Can you please add the same behaviour? This would help in "legacy" environments where you can't easily update gcc (which sadly has to matches gcov).

Unable to open /root/test.log

Attempting to use this plugin fails because it tries to open /root/test.log, which is inaccessible to most users. Removing the following lines appears to resolve the issue:

gcov7-viewer/gcov7-json.py

Lines 52 to 55 in 4c6aced

	file = open("/root/test.log", "w")
	file.write(os.getcwd() + "\n")
	file.write(" ".join(sys.argv) + "\n")
	file.close()

make log creation optional

Maybe only enable/disable it with an extra option and/or environment variable?
