VR3 can now be opened in a tab

[Thomas Passin]

The VR3 plugin can now optionally open in a tab in the log pane instead of in its own panel in the main Leo window (also referred to as a pane in the splitter).  I have attached a screen shot that shows the panel layout that I like when using VR3 in a tab.

There are two new commands to control that tab behavior:

vr3-tab -- opens VR3 in a tab

vr3-toggle-tab -- opens or closes VR3 in a tab.

I like to use an @button node in the @settings tree to make a button for vr3-toggle-tab. The button runs c.k.simulateCommand('vr3-toggle-tab').

vr3-toggle will close VR3 if open in a splitter pane as well as in a tab.  Next time, the command will open it in the splitter.  Conversely, vr3-toggle-tab will close VR3 in either a tab or the splitter, but will re-open it in a tab the next time the command is run.

An advantage to running VR3 in a tab is that you can open something else in a new splitter pane without interfering with VR3.

One minor drawback is that focus will switch to the log pane when something is written there - most likely when the outline has been saved.  Then you have to click in the VR3 tab to see it again.  I haven't found this to bother me much.

This new behavior has now been merged into the devel branch, so it's ready to try out.

This look interesting, thanks.

One thing I have never really needed, but occasionally wondered about; it is possible to *delete* a tab in the log pane? (perhaps it should be called the 'tab pane'?...)

Yes, as long as you know its name, which you do from its label:

    log.deleteTab(TABNAME)

I meant at the user level - right-click on a tab or similar... I occasionally have tabs 'outstay their welcome' (as in, I don't need their content any more)

I've been thinking they could be given a close box.  I've not looked in to what it would take, though.

I use an @button Delete-TAB

    TAB_name = g.app.gui.runAskOkCancelStringDialog(c,'Delete TAB',"Enter Tab name: ").strip()
    c.frame.log.deleteTab(TAB_name)  # delete named Tab

Is there a way to get a list of Tab names?

[Thomas Passin]

Yes:

log = c.frame.log
g.es(log.orderedTabNames())

BTW, here's how I found this.  I certainly didn't remember, and you may have a better way.  Start with the script for your button. It calls a method log.deleteTab.  In Leo's core code, similar methods are generally grouped together under the same parent node.  So I used the Nav tab - my favorite for searches - and typed in "deleteTab".  It returned two headlines that matched, one of which was "LeoLog.deleteTab".  I clicked on that entry and was navigated to that part of the code.  Then I just scanned the other names until I noticed "LeoLog.orderedTabNames".  That was it.

I usually find this to be the most effective way to proceed.  Sometimes you don't get a hit on a method or class definition but you find a place that it is called.  You can CTRL-click on its name in the code and Leo will (usually) succeed at navigating you to its def: or class: definition.

Now that I've gotten used to working this way, I don't know how I could stand going back to non-Leo ways of managing of code bases.

Here is an alternative way to delete a tab, where you type the tab name into the minibuffer.  The code can go into an @command or @button node:

"""Delete named tab from log frame. Get tab name to delete from minbuffer."""
def delete_tab():
    """State 0"""
    k = c.k
    k.setLabelBlue('prompt: ')
    event = {}
    k.get1Arg(event, handler = delete_tab1)

def delete_tab1(event):
    """State 1"""
    k = c.k
    # ----> k.arg contains the argument.
    tabname = k.arg
    log = c.frame.log
    log.deleteTab(tabname)
    # Reset the minibuffer.
    k.clearState()
    k.resetLabel()
    k.showStateAndMode()

delete_tab()

To be fair, many/most modern editors have some sort of 'find definition' and 'find references' feature

But only cff gives you the ability to organize the results.
