How does this work for you? I don't use this and haven't tested the changes.

Autocomplete

[Arjan]

I happened upon Python auto-completion somewhere in the docs (nice 
feature!). Upon first trying it, I got an exception:

autocompleter On
Traceback (most recent call last):

  File "/home/username/bin/leo-editor/leo/external/codewise.py", line 563, 
in cursor
return self.dbconn.cursor()

During handling of the above exception, another exception occurred:

g.es("No cursor for codewise DB, closed database?")

AttributeError: module 'leo.external.codewise' has no attribute 'es'


The completions did work, and strangely, upon restarting Leo and enabling 
autocomplete again I no longer see this error. But I thought I'd mention it 
in case it does indicate a problem somewhere.

Another minor issue: the autocomplete dialog appears two lines below the 
point where it's invoked. I'm using Leo 5.8 devel, build 20180227113208 Git 
repo info: branch = master, commit = 2c288fb7c15b Python 3.6.3, PyQt 
version 5.6.2, with the default theme.

Cheers,

Arjan

It works for me, but only in special cases.

The reason the *exact* example above works is that:

a) c.atFileCommands.write is *already* a valid completion and
b) c.atFileCommands.write is *also* a prefix of other at.FileCommands
methods.

In that case, 

auto_completer_state_handler is still active, and the '?' characters works.

Obviously, there are many other situations where you have typed a unique
method name, which causes auto_completer_state_handler to exit.  In those
more common cases, the '?' character won't work.

There is no quick fix for this.  Probably a new command is needed.

Please file a bug report.  Thanks.

Re: autocomplete: is it complete?

[wgw]

Thanks Edward,

I will put this in a bug report (in fact, the exact example does not work 
for me -- maybe a ubuntu thing).

I do think autocomplete is a crucial feature. Leo has such an enormous 
array of good code (and example code) that it is a shame to hide it. In 
fact, the ability to quickly get at what has been done in any project, all 
the way down to code that says x=1, is what allows a project to move 
forward. 

Object oriented programming probably owes much of its success to pure 
consultability. Autocomplete is part of that paradigm.

Re: autocomplete: is it complete?

One last thought about this: most projects that are Leo's size have api 
docs. I'm thinking of something like what you will find here: 
http://pyjs.org/api/ or, of course, here 
http://www.gwtproject.org/javadoc/latest/index.html 

Really, what will make Leo popular is getting more programmers involved. 
But convenient api documentation is a must for that to happen!

They're a recent addition, but they're up at 
http://leo-editor.readthedocs.org/, and they're updated nightly (3am

They are broken in some places, but that can't be helped when using 
readthedocs' infrastructure.  PyQt4 does NOT play with their sphinx

Re: autocomplete: is it complete?

Brilliant! A great step forward for anyone who wants to understand the code 
base and contribute. 

I will put in a feature request: 1) fix the qt dimension of readthedocs, 2) 
index leo on nullege (http://nullege.com) -- it indexes every string in the 
project-- and finally, one day, 3) do all that is done with readTheDocs and 
nullege in Leo!

Ouf!

I don't think the nullege search engine works, but you can do a Google 
search on any string in the nullege site: site:nullege.com areaslider in 
Google will find the AreaSlider pyjs class. But actually, you can find any 
piece of code you want and see the code tree and source. This is very 
useful to see how a given function is being used everywhere in the code 
base. 

Thanks for the readTheDocs link.

I spoke too soon: I see that readthedocs does everything nullege does. So 
nullege is unnecessary

I've submitted the nightly github mirror 
(http://github.com/leo-editor/leo-editor) of Leo to Nullege for 
crawling.  I couldn't submit the launchpad repo because nullege doesn't 
support bzr.


Whether it's needed or not, increased exposure is a good thing!

autocomplete: is it complete?

[wgw]

In the docs it says: 

When a single completion is shown, typing ‘?’ will show the docstring for a 
method. For example:

c.atFileCommands.write?

shows:

Write a 4.x derived file.
root is the position of an @file node



Does this work for anyone? (Very useful!)  For me, I get nothing, but 
autocomplete does complete after the dot.

Workaround:

g.es(c.atFileCommands.write.__doc__)

I agree.  I think it belongs in Chapter 5: Using Leo's commandes.

 The same section
 contains sub headings which are not bolded or otherwise marked to
 stand out from the text proper.

Both of these have been fixed at rev 3070.

I'll update the users guide online soon.

and calltips , which I think is out of place. The same section
contains sub headings which are not bolded or otherwise marked to

Wherever it finally lives, the autocomplete section should mention
that it needs to be turned on first with [Alt-1] and that the results
are displayed in the log pane; might help alleviate some confusion. :)

Re: Using codewise (autocomplete) with Tk

[Edward K. Ream]

On Thu, Dec 17, 2009 at 8:29 AM, Ville M. Vainio vivai...@gmail.com wrote:
 The version of codewise completer that works with Tk is now on trunk.

 It implements command codewise-suggest that prints the possible

 As such, it won't save you any typing, but it can help refresh your
 memory about available commands.

 Apart from that, the previous instructions for codewise still apply.
 If you actually want to save typing, some extra work needs to be done
 (by someone that actually uses the Tk ui and/or knows Tk).

Thanks for this.  I've put this on my to-do list.  No idea when I'll
get around to it.
