Interesting question.
First off, let's deal with your example code.
*doc = new LeoDoc("foo.tex")*
This could mean a number of different things. You might be wanting to
create a new Leo outline, a new @file node, or just a new node. You can do
each by hand, from with an existing Leo outline, or programmatically, using
Leo's API.
new outline: search for "def new" to see how Leo's creates outlines.
new @file node (or new node):
p = c.p # or p = c.lastTopLevel()
p = p.insertAfter()
p.h = "@file foo.txt" # or p.h = "@file %s" % (the_file_name)
*node = doc.getNode("bar")*
Assuming the script is in the outline containing a node whose headline is
"bar":
p = g.findNodeAnywhere(c, 'bar')
Otherwise, scripts can search in outlines in other tabs:
for c in g.app.commanders():
p = g.findNodeAnywhere(c, 'bar')
if p: # You've found the proper commander, and the proper node.
*print node.text*
print(node.b) # prints the body of node. Python 3 compatible ;-)
print(node.h) # prints the headline of node.
*Other considerations*> If I add the right Leo's metadata to the document
as Latex comments, I should be able to do this with Leo, something like:
Once you have created an outline, attaching "metadata" to any node is easy
using uA's, discussed here
<http://leoeditor.com/customizing.html#adding-extensible-attributes-to-nodes-and-leo-files>
.
Leo does support tex syntax coloring: @language tex.
Leo doesn't yet have a latex importer, nor direct support for @file x.tex.
However, it might be possible to read and write TeX files from Leo
using @comment
or @delims
<http://leoeditor.com/directives.html#part-4-dangerous-directives>. These
directives are dangerous, but might be useful.
HTH. I'm not sure I've actually answered your questions. Please feel free
to ask more.
