Automatically move to the beginning/end of line

[Brian Theado]

When moving down a text editor line-by-line, I rely on the common behavior of automatically moving to the end of the line when trying to scroll down past the last line. Similar for when scrolling up past the first line. Leo doesn't have this behavior, so I wrote the below script. Thought I'd share in case anyone else finds it useful.

@settings->@shortcuts:

previous-or-beginning-of-line ! text = Up

next-or-end-of-line ! text = Down

previous-or-beginning-of-line-extend-selection ! text = Shift-Up

next-or-end-of-line-extend-selection ! text = Shift-Down

@script

def lineScrollHelper(c, prefix1, prefix2, suffix):

    w = c.frame.body.wrapper

    ins = w.getInsertPoint()

    c.inCommand = False

    c.executeMinibufferCommand(prefix1 + 'line' + suffix)

    ins2 = w.getInsertPoint()

    # If the cursor didn't change, then go to beginning/end of line

    if ins == ins2:

        c.executeMinibufferCommand(prefix2 + 'of-line' + suffix)

@g.command('next-or-end-of-line')

def nextOrEndOfLine(event):

    lineScrollHelper(event['c'], 'next-', 'end-', '')

@g.command('previous-or-beginning-of-line')

def previousOrBeginningOfLine(event):

    lineScrollHelper(event['c'], 'previous-', 'beginning-', '')

@g.command('next-or-end-of-line-extend-selection')

def nextOrEndOfLineExtendSelection(event):

    lineScrollHelper(event['c'], 'next-', 'end-', '-extend-selection')

@g.command('previous-or-beginning-of-line-extend-selection')

def previousOrBeginningOfLineExtendSelection(event):

    lineScrollHelper(event['c'], 'previous-', 'beginning-', '-extend-selection')

Thanks for that, Brian! Exactly what is required!

By the way, recently I discovered another oddness.

When you select several lines at the moment and try to ident/deident them by a single 'tab' or 'ctrl->` - the line above/below the cursor is also affected.

This is not exactly what user expects.

Can't you give a clue how can this be fixed? Since you have already dived into the deepness of text editing commands.

I haven't seen this.  I suspect this happens only when the lines are continued.

Excellent work! Rather than relying on @script (or a plugin), I'll add these commands later today to Leo's core, and add do-nothing entries for the new commands to leoSettings.leo.  Users will then be able to bind them as they please in myLeoSettings.leo.

Completed at 2d736a in devel.

Yes, I've always noticed this behavior from Leo and rather than look into fixing it, I've trained myself when using leo to select one fewer lines than needed before I hit the tab key to indent. Maybe it isn't all that hard to fix it, but maybe some people don't see this behavior as "broken". I think it is because the cursor is on the line (even though nothing on that line is highlighted for selection). The indentation code probably operates on all the lines with selection as well as the line with the cursor.

Thanks a lot, Edward! I'll give it a try later.

I discovered when using my code on a mac laptop that I had to bind to Keypad-Up and Keypad-Down. Apparently the laptop keyboard on my mac doesn't have any keys mapping to just plain Up and Down.

Actually leo's indentation method is not common for text editors. I would rather say it is very uncommon.

In conjunction with leo's way to make 'ctrl-left' and 'ctrl-right' it makes impression that your memory and habbits are broken :-)
