Open file(s) basing on the text selected in the editor

[DV]

I was wondering whether NppExec already allow, for example, to open a file "C:\Program Files (x86)\Notepad++\change.log" when a text "Notepad++\change.log" is selected in the editor.
NppExec does allow this!

Here is NppExec's script required for this (please see the embedded comments for clarifications):

NPP_CONSOLE ?

// process the selected text...
SCI_SENDMSG SCI_GETSELTEXT 0 @""
set local F = $(MSG_LPARAM)
if "$(F)" == "" goto Done // no selected text

// check current file name...
set local n ~ strfind "$(FILE_NAME)" "$(F)"
if $(n) != -1 goto Done // current file name contains the selected text

// check opened files...
set local prev_fpath = $(FULL_CURRENT_PATH)
NPP_SWITCH $(F)
if "$(FULL_CURRENT_PATH)" != "$(prev_fpath)" goto Done // switched to another opened file

// check predefined directories...
NPE_CONSOLE v+ --
C:\tools\findfile.bat "$(F)"
if "$(OUTPUTL)" == "" goto Open
set local F = $(OUTPUTL) // found in a predefined dir
goto Open

:Open
NPE_CONSOLE v- --
NPP_OPEN $(F)
:Done

This NppExec's script uses external file "C:\tools\findfile.bat" which describes the set of predefined directories to be checked.
Here is the content of this "findfile.bat":

@echo off

for /D %%d in (
               "C:",
               "C:\Program Files",
               "C:\Program Files (x86)"
              ) do (
    if exist "%%~d\%~1" (
        call :EchoUnquotedString "%%~d\%~1"
    )
)
goto End

:EchoUnquotedString
    echo %~1
goto End

:End

The predefined directories in this example are ( "C:", C:\Program Files", "C:\Program Files (x86)" ).
Define your own set of directories here.

Here is how it works:
1) The NppExec's statement
C:\tools\findfile.bat "$(F)"
invokes the external batch file, passing the selected text as an argument to it;
2) (Inside of "C:\tools\findfile.bat") When "%%~d\%~1" exists, its full path is printed to the console output;
3) Then NppExec's statement
if "$(OUTPUTL)" == "" goto Open
verifies whether the output from "C:\tools\findfile.bat" is empty or not;
4) If it is not empty, we take $(OUTPUTL) as the file name to be opened:
set local F = $(OUTPUTL) // found in a predefined dir
5) Finally, the file is opened by
NPP_OPEN $(F)

High DV,
thank you very much for this script. I've done some modification to use git list file command inside a repository (git ls-files -- file_name ). It works perfectly fine.

I used "if <condition> goto <label>" command but I'd like to have a new command :
"if <condition> then <action_if_true> else <action_if_false>"
With this command, script would be easily written.

Thanks for your script
Christophe

From NppExec v0.6 alpha 1, the same script can look like the following:

NPP_CONSOLE ?

// process the selected text...
SCI_SENDMSG SCI_GETSELTEXT 0 @""
set local F = $(MSG_LPARAM) // the selected text
if "$(F)" != "" then // something selected
  // check current file name...
  set local n ~ strfind "$(FILE_NAME)" "$(F)"
  if $(n) == -1 then // current file name does not contain the selected text
    // check already opened files...
    set local prev_fpath = $(FULL_CURRENT_PATH)
    NPP_CONSOLE -
    NPP_SWITCH $(F) // try to switch to another file
    NPP_CONSOLE +
    if "$(FULL_CURRENT_PATH)" == "$(prev_fpath)" then // did not switch to another file
      // check predefined directories...
      NPE_CONSOLE v+ --
      C:\tools\findfile.bat "$(F)"
      if "$(OUTPUTL)" != "" then // found in a predefined dir
        set local F = $(OUTPUTL) 
      endif
      NPE_CONSOLE v- --
      NPP_OPEN $(F)
    endif
  endif
endif
