--vmodule Gives the per-module maximal V-logging levels to override the value given by --v. E.g. "my_module=2,foo*=3" would change the logging level for all code in source files "my_module.*" and "foo*.*" ("-inl" suffixes are also disregarded for this matching). Any pattern containing a forward or backward slash will be tested against the whole pathname and not just the module. E.g., "*/foo/bar/*=2" would change the logging level for all code in source files under a "foo/bar" directory.

How to use a command line switch?

The Chromium Team has made a page on which they briefly explain how to use these switches.

Conditions

These are rather technical. While most are pretty self-explanatory, keep in mind that any condition means that a switch isn't always available.

  1. The constants OS_FREEBSD, OS_LINUX and OS_SOLARIS must be defined.
  2. The constant OS_CHROMEOS must be defined.
  3. The constant OFFICIAL_BUILD must not be defined, and the constant ENABLE_PRINT_PREVIEW must be defined.
  4. The constant TOOLKIT_VIEWS must be defined.
  5. The constant OS_MACOSX must be defined.
  6. The constant GOOGLE_CHROME_BUILD must not be defined.
  7. The constant NDEBUG must not be defined.
  8. The constant TOUCH_UI must be defined.
  9. The constant OS_POSIX must be defined.
  10. The constants OS_CHROMEOS and OS_MACOSX must not be defined, and the constant OS_POSIX must be defined.
  11. The constant OFFICIAL_BUILD must not be defined.
  12. The constant OS_MACOSX must not be defined, and the constant OS_POSIX must be defined.
  13. The constants OS_LINUX and TOOLKIT_VIEWS must be defined.
