67159ee: a rewrite of leomail.py plugin

[Edward K. Ream]

The leomail plugin reads .mbox mail archive files into a tree of Leo nodes. 
This saves a lot of work.

Google " archive to mbox" for instructions on 
generating .mbox files.

The new code contains the following improvements:

1. It works with both Python 2 and 3. *The old code could corrupt .leo 
files* by including strings that the sax parser barfed on. The new code 
appears safe to use. The conversion involved tricky details in libraries, 
as well as the usual cursed bytes/string/unicode issues.

2. The new code organizes messages by threads.  Messages that start with 
"re:" become children of the node that started the thread.

3. Better warning and informational messages, and a better docstring.

Edward

P.S. I may add code that strips off cruft.

Re: Rev 112b14f: unl:// syntax creates clickable links between .leo files

[Largo84]

Good, finally figured out what that means, so I created a '@button 
get-unl`. That places the UNL in the log pane. What script command would 
copy it to the clipboard?

Re: Abbreviation default text

['Terry Brown' via leo-editor]

You could file an enhancement request, not sure how high the priority would be. 
Currently you can use  to enter a blank value for the field, and 
 to keep the default value for the field (because 
right-arrow clears the selection range).  With your change you'd have to 
explicitly blank (backspace, I suppose) default text you didn't want to remain.

Here's another abbreviation question. Is there a way to populate the variable 
field with default text that remains after moving to the next field? For 
example:
foobar;;=Use <|foo|> and <|bar|> in a sentence.
When the abbreviation is expanded (executed) the text `foo` is highlighted and 
I can add new text to replace it, then hit `,,` and go the the next field and 
`bar` is selected. Is it possible to leave `foo` and `bar` in place as defaults 
without having to retype them?
If not, would this be an appropriate enhancement request?

Just answered my own question. Instead of typing text to replace the 
default, simply press right arrow key before `,,` to advance to the next 
field.

I should have mentioned, there is a portable versions available

I assume this just creates local ini file or whatever else it needs
pulled from far flung directories 
nobody but the program would know how to find.

I often look for and would try or use a portable version.
these days, many will want to know if there is an app version.
ePIM does have one, not sure about AML Pages.
there is a python android app creator

Re: How to escape \n in abbreviations?

['Terry Brown' via leo-editor]

Ok, \\n should work in 9e9539d, there was special handling of \n in the code 
already that made \newcommand etc. impossible.  I think it unavoidably breaks 
theoretically possible abbreviations in people's local settings, but (a) they 
probably don't exist, and (b) better that than have the code unable to 
represent text needed for a demonstrated use case (\newcommand etc. in LaTeX).

That doesn't really answer the question. I use the `\:` syntax often to create 
new lines in abbreviations as you demonstrate. What I need is the text output 
to be `\n`. I need to somehow escape the `\n` such that when executed it 
doesn't generate a new line and strip out the `\n' string literal.

Done at Rev 24864e6. It passes all tests, but is more experimental than
usual. Please report any problems immediately.

The new code adds a new g.composeScript helper, called by the
goto-global-line logic. By itself, it's harmless. It's an example of a new
principle for me:

*Prefer small helpers to keyword arguments*

The effect of this principle is to reduce or eliminate catchall
functions/methods. These are really hard to debug and test.

However, there appear to be problems instantiating supposedly "pristine"
copies of the AtFile class. On closer examination, that's not all that
surprising. The init logic for AtFile does way too much.  I'd rather not
open that can of worms now, but I may not have a choice.

This may be related to Importer unit tests create both @clean and @file
. In my experience,
these supposedly minor problems can be symptoms of far more serious issues.
I must figure out what is happening before 5.5 b1.

As my brother Speed would say, progress is slow but slow ;-)

i.e. lines starting with \: are appended to the abbreviation (with a \n
between each).

If we're looking forward Leo should go with the full client/server based 
shell. This will facilitate a fully interactive Leo environment. I think 
anything less would hamper future efforts toward interactivity. This should 
also help knock out IPython integration issues. Two birds with one (larger) 
stone.

​Thanks for this report. ​

​​
​g.extractExecutableString needs a rethink. The present code will extract
code in *any *language, except reStructuredText and markdown.

But that's overkill, and wrong. A cff verifies that Leo presently calls
g.getScript only when we are about to execute *python* code.  Hardly
surprising.

This is good news.  ​​g.extractExecutableString can be simplified.  It will
return all and *only *lines under the control of @language python.
Furthermore, it will assume @language python initially.  This will kill
several birds with one stone:

- No more spurious "can not execute multiple languages" message.
- Simplifies the code.
- Allows python code to be freely intermixed with comments in *any* other
language.
