You may need to run the external tools (ex : compiler, interpreter or web browser) from Notepad++ (via Run dialog) by passing the current edited document as argument. To do so, you have to use the environment variable.
File level environment variables
The usage of environment variable is :
$( ENVIRONMENT_VARIABLE )
Say the current file you edit in Notepad++ is:
There are more environment variables containing information on the current session:
FULL_CURRENT_PATH : E:\my Web\main\welcome.html CURRENT_DIRECTORY : E:\my Web\main\ FILE_NAME : welcome.html NAME_PART : welcome EXT_PART : html SYS. : system's environment variable, e.g. $(SYS.PATH)
Note that you should put the double quote around the path environment variables :
"$(ENVIRONMENT_VARIABLE)" since they may contain some white space.
firefox "$(FULL_CURRENT_PATH)" iexplore "$(FULL_CURRENT_PATH)"
These 2 user commands are also included in npp.3.0.installer.exe (or later version). You can launch them by Ctrl+Alt+Shift+X and Ctrl+Alt+Shift+I respectively.
Document level environment variables
There are still more variables:
CURRENT_WORD : it gives the word(s) you selected in Notepad++. CURRENT_LINE : it gives the current line number where your cursor position is in Notepad++. CURRENT_COLUMN : it gives the current column number where your cursor position is in Notepad++. NPP_DIRECTORY : this variable contains the absolute path of Notepad++'s directory. PLUGINS_CONFIG_DIR : full path of the plugins configuration directory #N : full path of the Nth opened document (N=1,2,3...) #0 : full path to notepad++.exe LEFT_VIEW_FILE : current file path-name in primary (left) view RIGHT_VIEW_FILE : current file path-name in secondary (right) view
Knowing the plugin directory enables you to call any plugin function by passing the plugin name, function name and possibly arguments to rundll.exe. Or to unload a rogue plugin using regsvr /u.
http://www.php.net/%20$(CURRENT_WORD) http://www.google.com/search?q=$(CURRENT_WORD) http://en.wikipedia.org/wiki/Special:Search?search=$(CURRENT_WORD) $(NPP_DIRECTORY)\notepad++.exe $(CURRENT_WORD)
For the examples 1 ~ 3, we pass the argument URL + the current selected word(s) to the default browser in order to perform the search on Internet.
Whereas for the 4th example, it'll be useful if you want to open a file from current document. Consider a php file which contains a line:
Selecting ../myFuncs.php then typing the hot key you assigne to this command will open myFuncs.php in Notepad++, of course the mentioned file should exist in the indcated path.
The variable CURRENT_WORD brings you a flexible solution to configure your external commands
Running a command
When you use MppExec to run a command, the following variables are set for the command to use, before it is actually issued:
CWD : current working directory of NppExec (use "cd" to change it) ARGC : number of arguments passed to the NPP_EXEC command ARGV : all arguments passed to the NPP_EXEC command after the script name ARGV : script name - first parameter of the NPP_EXEC command ARGV[N] : Nth argument (N=1,2,3...) RARGV : all arguments in reverse order (except the script name) RARGV[N] : Nth argument in reverse order (N=1,2,3...) INPUT : this value is set by the 'inputbox' command INPUT[N] : Nth field of the $(INPUT) value (N=1,2,3...)
