question re: file clones and paths

[k-hen]

Hi Again,

There's a tip that says to clone your file nodes and put the clones in a 
folder at the end of the outline to match your output directories.
Also, there has been some notices recently regarding using @path 
directives, potentially recursively to simply your @file naming.
Both of these seem great.

I have this set up now, but some of the files aren't picking up the @path 
directives from the last node.
Also, not sure if this is related but performance has gotten significantly 
worse since doing this.

So  I'm not sure ... 
Is there a 'primary' version of the @file (or @clean in my case) which 
would define the @path? (I'm hoping it's the ending?)
i.e. does it matter if you clone from Section A to Section B vs Section B 
to Section A?
Should it only be the _contents_ of the file and not the actual @file 
headline node that gets cloned?
Should the @path's be higher up in the outline?
Should I just stick with fully qualified file names?

Loving Leo so far but I've still got lots to learn.

Thanks very much,
Kevin

Using the new insert-*-toc commands

[Edward K. Ream]

The new insert-jupyter-toc and insert-markdown-toc commands produce a toc 
(table of contents) for in the selected node, at insert point of the body 
text.  They replace any selected text.

These two commands are almost identical.  They very only in the details of 
how they generate the url part of markdown links.  See Note 2 below.

*Tip*: These commands produce a toc only for the selected node and it's 
descendants, but that is not a real limitation.  For example, you can 
produce a complete toc for an @auto .ipynb tree by executing the command in 
the @auto node itself, then cutting and pasting the toc into the first 
child of the @auto node.

*Notes*

1. You *must *use the insert-jupyter-toc command inside .ipynb files.  The 
Jupyter online notebook is picky about what links it will accept.  In 
particular, case is important in url's.  You probably should use 
insert-markdown-toc for all other files.

2. Both commands clean both parts of markdown links, that is, the *[*] part* 
and the *(*) part*. It's not clear what characters can be allowed in 
general, but for now the rules are:

A. Within [*] parts, all non alpha-nums are removed, except ":" and "-" and 
blanks.
B. Same for (*) parts, except that blanks are converted to "-".

3. Similar logic is used in the exporter to clean section names.

The cleaning of markdown links is over-zealous, but it's not clear exactly 
what characters are valid.  In particular, html escapes will not work.  

4. These two commands are defined in Leo's core. They are completely 
separate from the @auto (importer/export) logic.

*Summary*

These two commands are important tools.  Please try them and report any 
problems or desired improvements.

I will be happy to allow more characters in markdown links, should you want 
them. Just let me know.

The insert-markdown-toc is a component of #767 
: Add markdown command 
similar to rst3 command.

​Yeah, you have to have nbformat installed.  I'm working on better error
checking as we speak.​  The "real" code just works, but the itsy-bitsy
details are really important in this kind of code.

Rev 8e05a8d43 handles an import mixup that only affects python 2.

Re: Segmentation fault when run Leo on Linux

[Sebastian Silva]

Hi Edward,

Thanks for Leo. Still trying to figure it out. I installed on Debian
GNU/Linux 9.3 (Stretch) from Git.

I also found a Segmentation Fault when I attempted to run PyLint from
the UI.

Here's the logs in the terminal (nothing stands out, just segmentation
fault at the end, and crash).

(...)
:2: (WARNING/2) Inline substitution_reference start-string
without end-string.
:5: (WARNING/2) Block quote ends without a blank line;

Regards and Thanks,

Sebastian

Re: Please try @auto for Jupyter Notebooks

[Terry Brown]

p.s. I also got this in the @auto node,

@nocolor-node

Note: This node's body text is ignored when writing this file.

The @others directive is not required

but no children.  Not necessarily at the same time as the exception,
the above might have come from refresh from disk, whereas the Traceback
was on load of the .leo file.

Well, my aspiration was not a better way to edit notebooks, but a way
to execute code in a (possibly remote) Jupyter kernel, and get back
"rendered" results.

Nonetheless, what you describe sounds very cool so I'll try it :)

In my browser my notebook looks likes:

In [2]: import datetime
In [3]: datetime.datetime.now()
Out[3]: datetime.datetime(2018, 4, 10, 8, 33, 15, 831778)
In [4]: datetime.datetime.now().time()
Out[4]: datetime.time(8, 43, 15, 571086)

seems to be behaving as expected.  I've verified the file's
/home/tbrown/r/Untitled.ipynb

Log output

reading: @auto /home/tbrown/r/Untitled.ipynb
Traceback (most recent call last):

  File 
"/mnt/usr1/usr1/home/tbrown/t/Package/leo/git/leo-editor/leo/plugins/importers/ipynb.py",

ccdc3787 in devel fixes an undo bug

[Edward K. Ream]

The bug ruins undo in some cases. The fix strips "&" away before looking up 
a command name.  Recent changes to Leo's menus revealed this bug.

Here is yet another instance where devel is significantly better than 
master.  And no, releasing more often is not a complete cure. Yes, we could 
merge devel into master, but that could cause other problems...

The work-around is to install git and then use git to install Leo.  Please

Re: Please try @auto for Jupyter Notebooks

Yeah, yesterday was Monday, but I'm surprised nobody has commented about 
how awesome this is ;-)

Perhaps a lot of people don't know what I'm talking about.  Here is the 
script, j.bat, that I use. I execute it in a separate console: 

cd c:\test
jupyter notebook %*

The test directory contains the .ipynb files.  I open a new console and 
just type "j".  This starts the Jupyter server, which then opens my web 
browser on a Jupyter "home" page.  This page shows the contents of the test 
folder.  I select my test .ipynb and it appears in another tab.  Simple as 
that.

I can change any cell in Jupyter and save the file.  If the corresponding 
.leo file is running the new code appears in the @auto tree.  Simple as 
that.  I can also change the @auto tree.  The Jupyter web page will (I 
think) eventually reload automatically.  Or I can reload the page myself.  
Simple as that.

Please, please, give this a try and tell me what you think.  Imo it moots a 
lot of Jupyter-related work on Leo's to-do list.

Recent revs replace the @toc hack with the insert-jupter-toc command. 

I spent more than an hour experimenting with what should be allowed in 
urls.  This is quite tricky, and depends on undocumented features of 
Jupyter.  The present code generates toc lines as follows:

line = '%s- [%s](#%s)\n' % (
' '*4*(level-1),
clean_headline(p.h),
clean_headline(p.h.replace(' ','-')))

with:

def clean_headline(s):
# Surprisingly tricky.
# This could remove too much, but better to be safe.
aList = [ch for ch in s if ch in '-: ' or ch.isalnum()]
return ''.join(aList).rstrip('-').strip()
