@Ryan1729 That sounds like a reasonable plan to move forward -- since it is 
unknown what the effects will be, just make it an option to let those who want 
to use it, give it a shot and they can report if there are issues - fixing them 
where possible (although it probably will require an overhaul for handling 
selects at some point).

2017-12-21 Thread elextr
Enabling Scintilla multiple selections is easy, but everybody seems to have 
missed the following:

Geany and plugins are __not__ written to handle multiple selects, its is 
unknown what will happen in Geany or plugin functions if there is a multiple 
selection.  In the best case it will "just work" on the main selection and 
ignore the rest, in the worse case who knows, crash maybe.

Geany handles rectangular selections, but they are provided by Scintilla as a 
single selection, not multiple selections.

No plugin can change this as its in Geany and other plugins code.

Until the plan for introducing multiple selects addresses this it is likely to 
go nowhere.

2017-12-21 Thread Ryan Wiedemann
@sagarchalise That plugin relies on geany providing the functions 
`sci_set_selection_mode` and `sci_get_selection_mode`, that is geany already 
supporting rectangle selections. I suppose geany could expose the underlying 
functionality from scintilla for plugins and just not in its own GUI and let a 
plugin handle it. This might actually be a good way to get testing for multiple 
selection corner cases: users can opt-in by installing the plugin, with the 
expectation that some things might be weird/broken. Eventually multi-edit-mode 
could be moved into geany proper.

I'm not sure how to handle the mouse portion in this scenario though.

https://github.com/geany/geany-plugins/tree/master/geanyextrasel ? 

This is just a personal opinion but may be the workflow would be `multi edit

plugin.  While on `multi edit mode` disable other functionality related to 
`extrasel`  plugin.

Re: [Github-comments] [geany/geany] Multiple carets, selections, insertion points and paste (#1141)

2017-11-17 Thread elextr
IMO a few things are need to be resolved for this to progress:

1. As @AdamDanischewski said, some UI control is needed.  The prefect solution 
IMO is to extend the keybindings UI to allow binding to mouse buttons (with 
modifiers) as well, so called "clickbindings". 

Some mice have many buttons and these could be bound by the user to suit their 
use-case, while other users may keep the current ctrl-click and bind the 
multiple select elsewhere and others go for interapp compatibility.  Giving the 
user control takes the heat out of the debate about backward compatibility vs 
interapp commonality.

This would need a bit of work because the current keybindings are based on 
`gtk_accellerator` which does not handle clicks IIUC, but I think its just MMOP 
to have the click handler use bindings instead of being hard coded and to store 
and retrieve click to action mappings, eg in `clickbindings.conf` like 
`keybindings.conf`.

2. A plan is needed to introduce multiple select into Geany.  As has been said 
elsewhere, none of Geany is written to support multiple selects.  It would be 
my recommendation that multiple selects be introduced progressively instead of 
as one big lump. In practice the project does poorly with big lumps because it 
doesn't have the effort available to review and test them.  

But before _any_ multiple select capability is introduced it must be checked 
that _no_ other Geany and core plugin functionality is affected by their 
presence and any problems fixed.

Then  the basic ability to make multiple selections and type in them, as 
@Ryan1729 has here, can be added and contributions solicited for making other 
Geany functions multiple select aware when it makes sense for that.

3. The ability to style the secondary selections can be added, Scintilla can do 
it, so the settings "just" need to be added to Geany and appropriate colour 
schemes.

2017-11-17 Thread AdamDanischewski
Since the current default behavior is different, it may be argued to not make 
it a default. Yet the functionality seems to be much better and I personally 
would prefer to see Geany remain consistent with other editors that offer this 
same functionality. It is a quirk in my opinion that Geany using Scintilla 
defaults to a different functionality than what the other Scintilla editors 
have as standard with regards to multi-caret on Ctrl-click. 

I vote to make the new Ctrl-click functionality standard in accordance with the 
other Scintilla editors. 

Btw: you are in the same situation, I was in, with regards to fixing it yet not 
being able to add it to the user interface. Hopefully elextr knows how to route 
this to the appropriate parties for implementation.

Re: [Github-comments] [geany/geany] Multiple carets, selections, insertion points and paste (#1141)

2017-11-17 Thread Ryan Wiedemann
I've now got ctrl-click multiple selections working, (I can make multiple 
selections and type into all of them at once) on my [debugging 
branch](https://github.com/Ryan1729/geany/tree/ryan1729debug). Note that that 
branch  simply deletes the old ctrl-click functionality, (and has a bunch of 
printouts besides), so it' is not suitable to add to the main codebase, but it 
works as a proof of concept. 

So the question now seems to be how should the settings for ctrl-clicking be 
handled? The natural thing to do right now seems (to me) to be a set of radio 
buttons, (and a corresponding enum) that allows selecting between the old 
functionality (goto-tag and find-matching-brace), adding a selection, and not 
doing anything on ctrl-click at all. However, that old discussion thread 
mentioned the idea of mouse bindings, (so the user could bind arbitrary actions 
to mouse inputs,) which seems like a reasonable idea. If that's ever going to 
happen, then we should probably think about that when deciding how this setting 
works. If we go with my enum proposal then later mouse bindings get added, then 
either user's configuration files break or we have one of two undesirable 
situations : this enum overrides the keybindings, meaning the user might set 
mouse bindings and not understand why they need to set the enum to "None" or an 
additional setting of "Allow keybinding", or the other situation where the 
keybindings override the enum and if a user binds something to ctrl-shift-click 
and is surprised that ctrl-click stops doing what they expect.

Then again, would not having either setting override each other be best? If a 
user is surprised that ctrl-clicking adds a selection, in addition to whatever 
they set it to do, then hopefully that would prompt them to look in the 
settings to turn that off? Maybe someone else has a better idea that avoids 
even that problem?

Textadept is blazing fast, but I miss two features:

1. a "word/character counter" (not just for the file but also for a selection)
2. a "find and mark-all" (preferentially like Geany's Ctrl+shift+M)

I currently use Visual Studio Code, because it has all the features I use and 
has many useful extensions. The downside is that its not as fast as Geany or 
Textadept. But its faster than any other text editor with similar functions.

2017-11-17 Thread AdamDanischewski
Kind of like textadept now that I've played around with it, you have to a hack 
a colorizer (theme) to get the color scheme to Geany though. Copy and modify a 
theme in the themes directory under the source directory (exploded tar ball). 

Presuming you named your cloned theme to be "your-new-theme". Add this to your 
~/.textadept/init.lua file: 
ui.set_theme(not CURSES and 'your-new-theme')

Then modify the colors and type Ctrl-E for a command window in textadept and 
enter: reset() 

Keep modifying it to your preference (hint you can choose more than the colors 
listed (e.g. colors.red works), once you get the color scheme you like it's not 
that different from Geany, and it seems a lot faster.

2017-11-13 Thread Ryan Wiedemann
I've got a branch [here](https://github.com/Ryan1729/geany/tree/ryan1729debug) 
that callsSCI_ADDSELECTION on ctrl-click, and calls SCI_ROTATESELECTION on 
ctrl-right-click. Mysteriously, if you ctrl-click then ctrl-right-click 
somewhere else, by the time the right click happens, the number of selections 
is back down to 1. So I also quickly co-opted the dubug mode for the `SSM` 
macro to print out the selection count when every message is sent to Scintilla, 
(though that macro anyway.) Surprisingly, the selection count goes back to 1 
before the first other message is sent! I find this extremely odd since the 
only ways to remove the other selections with the Scintilla API, as far as I 
can tell, are in the section which I only added wrappers for in that branch.

Unless someone knows some weird thing the code is doing that wold cause this, 
(setting the selection outside the Scintilla API?!) I suppose I'll have to try 
getting GDB working.

2017-11-13 Thread Ryan Wiedemann
Just to be absolutely clear what we're talking about, here's a gif recording of 
an unconfigured SciTE 4.0.2:

![scite_multiple_selections](https://user-images.githubusercontent.com/2133026/32747877-772038a2-c877-11e7-97cd-4a47153ef1b3.gif)

In the gif I `Ctrl-click` twice (unfortunately you can't see my mouse,) to make 
two additional selections, perform some edits, then simply left click to go 
back to a single selection.

I guess I was assuming Scintila handled more of the GUI, rather than, as 
appears to be the case, just managing the editor state.

@AdamDanischewski Those seem like good suggestions. assuming extra selections 
are actually working, just not showing in the UI, SCI_ROTATESELECTION should 
allow a quick demonstration that will actually show up. I'll get started on 
that.

2017-11-13 Thread AdamDanischewski
Lol, yea I was only scrolling up only to his new comment for some reason - 
disregard the clarification request. I see what you are looking for now, best 
of luck. I developed the first patch for the multiselect functionality that's 
working now. I didn't implement it ultimately in Geany because of the user 
interface complexity. What I did was simply hook the functionality to an 
existing loaded user interface component for testing - to make sure it was 
turned on. That way you don't have to worry about the user interface - you can 
just turn on the functionality and test that it works then upload what you have 
and ask a developer to integrate it into the user interface. 

As far as the Scintilla functions, I think these may be the ones you want to 
play around with: 
SCI_SWAPMAINANCHORCARET moves the caret to the opposite end of the main 
selection. SCI_ROTATESELECTION makes the next selection be the main selection.
SCI_MULTIPLESELECTADDNEXT adds the next occurrence of the main selection within 
the target to the set of selections as main. If the current selection is empty 
then select word around caret. The current searchFlags are used so the 
application may choose case sensitivity and word search options.
SCI_MULTIPLESELECTADDEACH is similar to SCI_MULTIPLESELECTADDNEXT but adds 
multiple occurrences instead of just one. 

Look in the Geany code where SCI_SETMULTIPLESELECTION is set, to see how to 
turn on these on then look at the keybindings code to see if you can remap them 
to buttons (easier for testing).  Try to focus on one thing that you can see 
working or not to get it going then ramp it up the full functionality.

What exactly is expected, I can't get Scite to do anything interesting on 
crtl+click.  The version in my distro is kind of old (3.6.0) and maybe it was 
added after that.

How do you know it didn't work? IIUC multiple selections have a separate 
styling from the main selection, and since Geany doesn't set that style they 
may not be visible?

2017-11-12 Thread Ryan Wiedemann
I had assumed that it was built in to Scintilla since [that docs page I 
mentioned 
before](http://www.scintilla.org/ScintillaDoc.html#MultipleSelectionAndVirtualSpace)
 [1] seems to be about Scintilla only and it explicitly mentions `Ctrl` in 
conjunction with the mouse. I had also tried `Ctrl-click` in SciTE and that 
worked as expected. After a cursory `grep` through the latest Scintilla and 
SciTE, I didn't find `Ctrl-click` logic in either of them. There's some kind of 
autogenerated interface in SciTE which makes things like this hard to search 
for there, though. I did stumble across the logic for the selection adding 
behaviour bound to `Ctrl-D` in Sublime Text. Altogether that suggests to me 
that the `Ctrl-click` behaviour is probably in SciTE, not built-in`to Scintilla.

So I've now tried calling `SCI_ADDSELECTION` on `Ctrl-click`, in the same place 
I removed the code from, but it still doesn't seem to do anything. I've 
confirmed it makes it to the right part of the big switch statement in the 
local copy of Scintilla though. 

[Here's the 
diff](https://gist.github.com/Ryan1729/2244914f0ac7856fed42f8379fb4cd36).




[1] Regarding the link, I meant to do something [`like 
this`](http://www.scintilla.org/ScintillaDoc.html#MultipleSelectionAndVirtualSpace).
 I've put the backticks inside the square brackets this time. I knew there was 
a way that it worked.

@Ryan1729 good on you for trying.

One thought on why it does nothing is that something has to do the selection, 
are you sure Scintilla has a default binding for `ctrl+click` that does 
multiple selection?  If not you need to add it, or add it to Geany in place of 
the code you deleted.

> Per comments above I expected some parts not to play nicely with multiple 
> selections

I would expect _everything_ to simply ignore multiple selections, and just read 
the main selection and operate on that.  And thats where the "significant 
change" part above comes in.

The `enable-multiselection` branch is not in the Geany repository, or any PR 
(AFAICT) so it a private one at best in that persons github repository.

PS removed the backticks around your link so it would work, markup is ignored 
inside backticks.

2017-11-12 Thread Ryan Wiedemann
This feature is just about the only thing holding me back from switching away 
from another editor for everything, so I thought I would take a stab at it. I 
cloned master and added a wrapper for 
`[SCI_SETMULTIPLESELECTION](http://www.scintilla.org/ScintillaDoc.html#MultipleSelectionAndVirtualSpace)`
 in `sciwrappers.c` and unconditionally called it in  `create_new_sci`, 
(presumably the final version should be behind a checkbox or something.) But 
that didn't appear to do anything, (specifically I tried Ctrl-clicking to place 
multiple cursors.) Just by searching "geany ctrl click" I found [this 
discussion 
thread](https://lists.geany.org/pipermail/users/2012-May/008026.html) that 
mentions that Ctrl-clicking is hardcoded to goto-tag and find-matching-brace 
depending where you click. So I found [the part of the code that does 
that](https://github.com/geany/geany/blob/dd58ab6f49e8b382d9278c3ebc533f08b8aec84e/src/editor.c#L316-L327)
 and removed it. But Ctrl-clicking still doesn't work. Per comments above I 
expected some parts not to play nicely with multiple selections, but I hoped 
what I did would be enough to get it working some of the time! I managed to 
make the small changes I did by just `grep`ping trough the code and checking 
that functions were called when I thought they were being called. Does anyone 
else with more knowledge of the codebase have any ideas what else might cause 
Ctrl-clicking not to work?

FWIW, [further 
on](https://lists.geany.org/pipermail/users/2012-May/008041.html) in that 
discussion I linked to, an `enable-multiselection` branch was mentioned. Now I 
don't know the history of this project, but that discussion is from 2012. Is 
there any chance that branch would be even slightly relevant to the current 
codebase, assuming the author still has it and can be contacted?

@AdamDanischewski its definitely only possible to have one selection still, you 
havn't confused it with rectangular selection have you?

It looks like the multi-select copy/paste insert portion of this request was 
added as of 1.23.1.

Which is why its a significant change.  

`Carelessly` is probably harsh, it was simple written with no intention of 
handling multiple selections.

Scintilla (the editing component Geany uses) can do that.  So it's a "mere 
matter" of adding UI capability to Geany (and design how it should actually 
work from a UI perspective).

And it possibly requires enhancing several parts of Geany so it plays nicely 
with multiple selections (I'm afraid a lot of our code was written carelessly 
to that regard, or even way before the feature even existed in Scintilla).

[Github-comments] [geany/geany] Multiple carets, selections, insertion points and paste (#1141)

2016-07-15 Thread mprz1024
It would be great to have the ability to create multiple carets, select 
multiple pieces, or progressively clone a selection of a word to the next 
identical match creating multiple selections, not necessarily square, and then 
be able to type, delete, replace, etc. using the multiple carets until Esc is 
hit, pasting into all carets with Ctrl-V, and so on.

Here's an animated demonstration of these features: https://www.sublimetext.com/

This is Sublime Text's killer feature, and this would put Geany closer to one 
of the most reputed, feature rich commercial multiplatform editors, while still 
being free software. I believe there's support for this in Scintilla, at least 
to some extent.

This supersets #850.
