Editor right-click, outside current text selection, lose this selection



  • I wonder if explaining why it is very useful to me is needed.

    first example : (I copy a lot between different tabs and different applications)
    Some text is selected in a notepad++ tab, or any application window, that I need to copy repeatedly.
    I activate this tab or window with ctrl+tab/alt+tab, right-click anywhere and ‘copy’,
    go back to the other app and right-click anywhere and ‘paste’.
    So, I do not have to point every time the selection or the caret for copying/pasting.

    second example :
    I select some text in a notepad++ tab with the mouse, and immediatly right-click to copy it.
    If I have moved just a pixel farther than the selection, then I lose the selection and can not copy it.

    Added benefit : Since I can right-click anywhere, I do not have the context-menu appearing above the selection,
    so I can check my selection is good…

    indeed Microsoft Visual Studio (when editing Microsoft Word macro) is one of the infamous selection-looser
    Internet Explorer 11 also…

    Here is the improved code

    • code has been hardened against errors
    • the hook still can not be removed (*see below the code why),
      but now can be “de-activated”/“re-activated” by re-running the script
    • now hooks all scintilla windows (so incuding the notepad++ second view when splitted)
    • added : SHIFT + double left mouse click -> select text from click point until next space/space-like chars

    (sorry the two functions SHIFT+double-left-click and right-click can not be “de-activated” separately,
    I think a dialog prompt and two separate variables set by console.editor.SetProperty would do that)

    # PythonScript which hooks mouse clicks (WndProc HOOK on Scintilla windows)
    # * SHIFT + double left mouse click : select text from click point until next space/space-like chars : \s
    # * right mouse click : prevent right-click from moving the caret and losing current text selection
    # re-run the script to de-activate/re_activate the hook
    # Tested on NPP 64 bits (NOT tested on 32 Bits but could be compatible), /!\ this file uses TABS for indent

    *Breaking the hook chain :
    If a hook is set by

    self.NewWndProc = WndProcType(self.MyWndProc)
    oldwndproc = SetWindowLong(win_hwnd, GWL_WNDPROC, self.NewWndProc)
    

    and then removed by

    SetWindowLong(win_hwnd, GWL_WNDPROC, oldwndproc)
    

    that breaks the hook chain if there is more than 1 hook.

    original WndProc funcA > hooked by MyWndProc funcB > hooked by MyOtherWndProc funcC
    if funcB hook is removed, than funcC will not receive any message after that, and will not be aware of it

    Some more sophisticated hook api could solve that problem but I don’t know them.
    I chose the easiest way, which is to “de-activate” my hook by just telling him to do nothing,
    except silently forwarding the window message to the the next WndProc (oldwndproc).
    This way my “de-activated” hook does nothing but does not break the hook chain.



  • @frying-pan said in Editor right-click, outside current text selection, lose this selection:

    I wonder if explaining why it is very useful to me is needed.

    Not needed, but often I give people that at first seem to want odd things a “hard time” about it, and it draws them out into explaining/justifying their need.

    Future readers that come along then get the whole story, and maybe don’t dismiss something that could really be of use.

    I think you have done a good job of that, as well as solving your own problem with the script. Nicely done!



  • @Alan-Kilborn

    Well, I would not have made Notepad++ my default text editor, if I couldn’t have solved the right-click question.

    It’s the first reason I bothered to install PythonScript and learn this syntax (while I’m only accustomed to Pascal/VB/VBS/AutoIt)

    And otherwise I use PSPad for its Project features, Notepad++ session and workspace are not as featured.
    PSPad is mostly missing code wrapping (if > endif, etc…)



  • Oops, I forgot to delete 3 lines of old code (at line 141 of the script). But I can’t modify any more the previous post.

    So the code updated without the bug :

    # PythonScript which hooks mouse clicks (WndProc HOOK on Scintilla windows)
    # * SHIFT + double left mouse click : select text from click point until next space/space-like chars : \s
    # * right mouse click : prevent right-click from moving the caret and losing current text selection
    # re-run the script to de-activate/re-activate the hook

  • Code update, probably the last for this script, since I have all the keyboard + mouse shortcuts I need.

    • corrected one bug :
      (in case of a Scintilla window hook failure, the list of hooked WndProcs was incorrectly shortened and enumerated)
    • cleaned the code
    • added more keyboard + mouse shortcuts :
      • SHIFT + double-left-click : select from clicked point the whole variable name : alphanumeric with _ and . (dot)
      • CTRL + SHIFT + double-left-click : select from clicked point the whole bracket content : () [] {}, from left in case of mismatch
      • ALT + SHIFT + double-left-click : select from clicked point the whole quote content : “” ‘’, from left in case of mismatch
      • ALT + right-click : select from clicked point until space/space-like characters are met : space/tab/cr/lf/formfeed/vtab etc…
      • right-click : prevent right-click from moving the caret and losing current text selection
    • added options to disable each shortcut separately (these options values must be edited in the script file)

    note : my code rendering would be better if I could set up the real tabs to appear as 4 chars wide on this forum
    (I prefer to have 4 chars wide tabs in Notepad++ but this forum render them as 8 chars wide)

    note: since the code is too long to be loaded in one post, it will posted in two chunks.

  • Hey ! the forum changed the line 313 of my uploaded code

    line 313 was uploaded as :
    (I must replace \ by BKL to have it displayed)
    s_pattern_sqr = “BKL[BKL]”
    but is displayed without the \ as :
    s_pattern_sqr = “[]”

    which breaks the ‘CTRL + SHIFT + double-left-click’ feature : select brackets content : () [] {}

    having compared the whole uploaded code with my original code there should no other error
    (I used a simple file compare utility to do that : ExamDiff)

    So there is a bug in the text parser of the forum :
    the preview is ok but the final post has lost the backslashes



  • @frying-pan
    Wow, that’s quite a script. Maybe post to GitHub or a Gist and then link from here to that post?

    Cheers.



  • This post is deleted!


  • @Michael-Vincent

    Uploaded on GitHub the last posted script in this thread, as version v1 (without the backslash error)

    [https://github.com/frying-pan/NotepadPP-PythonScript-Mouse-Gesture/blob/master/Perso_ScintWndProc_Hook.v1.py](link url)

    and made a version v2.0 : with some code cleaning and more object_oriented style

    [https://github.com/frying-pan/NotepadPP-PythonScript-Mouse-Gesture/blob/master/Perso_ScintWndProc_Hook.v2.0.py](link url)



  • @frying-pan
    Because of file name changes, above links are not valid any more,
    see below for new links to each repository.



  • An update of :
    Perso_ScintWndProc_Hook_v1_0.py to Perso_ScintWndProc_Hook_v1_1.py and
    Perso_ScintWndProc_Hook_v2_0.py to Perso_ScintWndProc_Hook_v2.1.py for the same small bug

    Update to Perso_ScintWndProc_Hook_v3_0.py with new features :

    • option to select brackets/quotes with content
    • option to auto-copy selection to clipboard and/or console
    • expand selection from a previous selection
      -> now requires the two libraries : Perso__Lib_Edit.py, Perso__Lib_Window.py

    all files provided in the GitHub repository :
    https://github.com/frying-pan/NotepadPP-PythonScript-Mouse-Gesture

    ===

    And another small python script to tweak the CR and LF graphic :
    these changes can be applied at each Notepad++ start by running the script from startup.py

  • I take advantage of this thread to advertise about two other python scripts that I wrote:

    +++

    Bracket Indicator : highlight the bracket () [] {} where is the selection/caret
    based on BracketHighlighter.py idea, with easier customization for highlight style,
    a different algo for highlighting (using the ‘re’ regexp object, possibly more efficient),
    following the brackets matching rules of Scintilla

    RestartNPP : to restart Notepad++ remembering the current session (opened file),
    can possibly made into a button, and be run with a keyboard shortcut via ‘Shortcut Mapper’
    can be handy when developping a script/plugin

    +++

    Perso_ScintWndProc_Hook was renamed to FP_MouseSelectGest_Hook, and updated
    Perso_CrLfDisplay_Callback was renamed to FP_CrLfDisplay_Callback, and updated

    FP_MouseSelectGest_Hook, FP_BracketIndicator_Callback and FP_CrLfDisplay_Callback
    can be run from startup.py on each NPP start (with pythonscript option : initialisation=ATSTARTUP)

    All four scripts have options at the top of the main script file that can be changed by the user
    Some of these scripts use libraries which are provided in the same Github folder as the main script

    Here is the root of the Github repositories :
    https://github.com/frying-pan?tab=repositories

    and the four repositories for the four scripts :

  • This thread got rather out of control.

    Anyway, I’m back to say that I did change my mind and I like the very first basic functionality this thread introduced: The ability to not lose your selection if you right click somewhere not on that selection.

    However, I noticed that it isn’t compatible with one of the new features of Notepad++: The ability go right-click the bookmark margin and get a right-click popup menu of bookmarking functions.

    I like the idea of both features; I wonder if there is some way to get both functionalities. Hmmm…



  • @Alan-Kilborn

    "This thread got rather out of control."

    I could create a separate thread to describe and post the links for the 4 scripts I have made available on Github

    "However, I noticed that it isn’t compatible with one of the new features of Notepad++: The ability go right-click the bookmark margin and get a right-click popup menu of bookmarking functions."

    I have NPP 7.8.2 and the right-click on the bookmark margin has been introduced later, so I can not test this for the moment
    (I guess the right-click context-menu on the bookmark margin does not appear at all…)

    I could discriminate between right-clicks on the margin or the text by pixel position,
    I will need the widths in pixels of all left margins :
    the function “editor.getMarginWidthN(margin_index) → int”, gives that for each margin_index,
    but I don’t know how many of margin_indexes must be checked (probably 5, from 0 to SC_MAX_MARGIN (4)),
    the function SCI_GETMARGINS (that gives the number of margins) seems to be missing from the NPP Scintilla commands

    Possible workarounds :
    My script does not intercept shift+right-click, so it could be tried on the bookmark margin
    (in case this context-menu is not sensitive to the shift key, which is often the case for context-menus)

    Also control+right-click and alt+right-click can be disabled in my script
    (there is a middle-click alternative for these features)
    to see if they trigger the bookmark margin context-menu, which seems less likely…



  • @frying-pan

    I noticed that the feature that this thread started with is being implemented natively in Notepad++. See HERE.



  • @Alan-Kilborn

    ok i see
    [https://github.com/notepad-plus-plus/notepad-plus-plus/pull/8564](link url)
    ‘Keep selection when right-click outside of selection’ has been added, or will be added to the next NPP version (as an option).

    So I will remove this specific feature from my
    NotepadPP-PythonScript-Mouse_Select_Gesture script
    once I have updated my NPP and tested the native option.
