// Basic Plugin Logging Usage Instructions
|
|
//
|
|
// 1. Set this environment variable: NSPR_LOG_MODULES=<name>:<level>
|
|
|
|
// Choose the <name> and <level> from this list (no quotes):
|
|
|
|
// Log Names <name>
|
|
#define NPN_LOG_NAME "PluginNPN"
|
|
#define NPP_LOG_NAME "PluginNPP"
|
|
#define PLUGIN_LOG_NAME "Plugin"
|
|
|
|
// Levels <level>
|
|
#define PLUGIN_LOG_ALWAYS mozilla::LogLevel::Error
|
|
#define PLUGIN_LOG_BASIC mozilla::LogLevel::Info
|
|
#define PLUGIN_LOG_NORMAL mozilla::LogLevel::Debug
|
|
#define PLUGIN_LOG_NOISY mozilla::LogLevel::Verbose
|
|
|
|
// 2. You can combine logs and levels by separating them with a comma:
|
|
// My favorite Win32 Example: SET NSPR_LOG_MODULES=Plugin:5,PluginNPP:5,PluginNPN:5
|
|
|
|
// 3. Instead of output going to the console, you can log to a file. Additionally, set the
|
|
// NSPR_LOG_FILE environment variable to point to the full path of a file.
|
|
// My favorite Win32 Example: SET NSPR_LOG_FILE=c:\temp\pluginLog.txt
|
|
|
|
// 4. For complete information see the NSPR Reference:
|
|
// http://www.mozilla.org/projects/nspr/reference/html/prlog.html
