18 // Basic Plugin Logging Usage Instructions
19 //
20 // 1. Set this environment variable: MOZ_LOG=<name>:<level>
21 
22 // Choose the <name> and <level> from this list (no quotes):
23 
24 // Log Names            <name>
25 #define NPN_LOG_NAME    "PluginNPN"
26 #define NPP_LOG_NAME    "PluginNPP"
27 #define PLUGIN_LOG_NAME "Plugin"
28 
29 // Levels                <level>
30 #define PLUGIN_LOG_ALWAYS mozilla::LogLevel::Error
31 #define PLUGIN_LOG_BASIC  mozilla::LogLevel::Info
32 #define PLUGIN_LOG_NORMAL mozilla::LogLevel::Debug
33 #define PLUGIN_LOG_NOISY  mozilla::LogLevel::Verbose
34 
35 // 2. You can combine logs and levels by separating them with a comma:
36 //    My favorite Win32 Example: SET MOZ_LOG=Plugin:5,PluginNPP:5,PluginNPN:5
37 
38 // 3. Instead of output going to the console, you can log to a file. Additionally, set the
39 //    MOZ_LOG_FILE environment variable to point to the full path of a file.
40 //    My favorite Win32 Example: SET MOZ_LOG_FILE=c:\temp\pluginLog.txt
41 
42 // 4. For complete information see the Gecko Developer guide:
43 // https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Gecko_Logging
