Short cuts

May it be possible to redefine short cuts?

* ctrl shft Z -> ctrl Y
Most programs use ctrl Z (undo) like Librecad but ctrl Y for redo (Librecad: ctlr shift Z)

* ctrl K -> ctrl shft A
Gimp expects ctrl shift A for unselect, Librecad ctrl K.

Ferdi,

changing the short cuts in the source code is possible of course, but this may upset user who are already familiar with the current ones.

I think, what we would need first, are configurable short cuts. Then we can think about changing the defaults. That gives every user the choice to change to new standard short cuts or change them back or completely different for personal  preference.

Can't expect for the moment how much work this would be and when it could be implemented.

I think Ctrl+C, Ctrl+V, Crtl+Z and Crtl+Y are almost universal. Nothing too hard to get used to.

Don't forget that ctrl-c  ctrl-v (or cmd versions for OSX) nice, but in a CAD world we need to be precise.
What should d happen when you do 'ctrl-v'? Should it paste at the cursor position? What's the reference position?

It's not as simple as let's put XYZ on the clipboard and/or copy it back from it.
I di agree that having ctrl-v/ctrl-c working cross platform AND between different applications would be sweet. Unfortunately that may be a lot of work. Is there anybody that can step forward and do some research?

Another good idea would be a window with a list of the last operations showing everthing you do. It would be helpfull specially when undoing operations that change nothing on the screen.

About helping on developing, I know almost noting about it. But if some orientation comes, I can try.

Hi,
I read a discussion of shortcuts and would like to write a few notes and observations.
I work as a civil engineer with AutoCAD over 15 years and with other smaller CAD applications.
I watch for a long time this project and I really like it.
Unfortunately I do not have time to get involved with, in all the time I only installed and inspected the source code.

1)
Each command or shortcut typed on the command line should be confirmed. AutoCAD is confirmed SPACE or ENTER.
Confirmation does not stay away from work and solve the problem with similar abbreviations.
Eg. l = line, polyline = ll, lll = rectangle. The more commands, the more necessary the confirmation.

2)
I studied "rs_commands.cpp" may not fully understand all of the links, but I have some observations.

2a)

2b)
Definition command shortcuts in the "rs_commands.cpp" I find it complicated.
I think there should be defined only basic command such as mainCommands.insert ("_line" RS2 :: ActionDrawLine);

2c)
Custom command names should be defined "librecad.alias" as the format
_line: line,l,if
_circle: circle,c,ci,yyya

Thus, I think it would be very transparent to the user and thus should complete control over the definition of shortcuts.

Also, there could be defined hotkeys or possibly action with the mouse (eg. CTRL + left mouse button)
_save: *CTRL+S,save,s,sa
_regen: *CTRL+*LB,regen,rr

3)
I think that every action should have a comment on the command line.
When I press CTRL + S for example, in addition to saving the file should appear in the command line command executed.

Rather, it would be appropriate to every hotkey/ command menu / click on the icon
sent the appropriate command in the command line processing.

Autocad thus allows the ICON each define a custom command. This is useful for commands with multiple options.
e.g.
circle;3P - switches on the insert mode by entering the circle of three points
circle;CR - switches on the insert mode by entering the circle center and radius

4)
Press Enter or SPACE in an empty command line should call the previous command.
Even that which was specified via hotkeys (eg CTRL + S)

5)
Press the up arrow should be inserted into the command line recently sent commands / text and allow its editing.
It's handy for repairs typos when entering long commands.

6)
Very useful is the automatic bidding orders over entering the name of the command / shortcut to the command line.
eg "pol" - offers "polyline", "polylineedit", etc.

XXX)
One idea in the distant future, which is not in AutoCAD.
Dialog, which would be able to show something like the command line (or the ability to turn on the display in command line),
where they used to continuously record the internal variables / settings.
There should be the possibility to change any settings possibly invoke help.
Eg.
using Autocad mirror has two variants mirroring texts - Yes / No.
This is controlled by an internal variable that is necessary to remember it or complex search.
It is similar to the other commands, is a large set of variables that control their behavior and not all are easy to find and set.

It would be good to know which settings were used when calling the command.
I do not know exactly how this is now solved in LibreCadu, but sooner or later you will have to deal with process
a large number of settings and this would be appropriate to deal with at the same time.

David,

Thanks a lot for your detailed analysis.

Clearly, it will take some time for us to design the command line framework based on your suggestions.

With help from our small community, LibreCAD will be evolving fast.
