Message-ID: <199607071749.NAA07006@weyr.CNRI.Reston.Va.US> As I promised David Arnold at IPC-IV, I've finally gotten around to cleaning up my modified version of docco and have it working fairly cleanly for both Python 1.3 and Python 1.4b1. I've written some documentation on the conventions it uses for interpreting docstrings; these notes are available at http://weyr.cnri.reston.va.us/progenv/conventions.html. The modified version of docco can be had at http://weyr.cnri.reston.va.us/progenv/docco.tar.gz. There is not a public link to it right now since I'm currently most interested in comments from others in this group on how I'm interpreting the docstrings.

Element (a) deals with setexts that arrive via email and end up being parsed (processed) as unedited mailbox files; fully employed the (a), (b) and (c) make it possible to distribute "multisetexts", i.e. setexts with one additional level of logical structure (= more than one setext per message; more than one message in a mailbox). If such file is viewed as a multisetext it will result in 3-level-outline structure: mail-subjects become top-level chapters, setext titles denote subchapters (topics) and the subheads yet finer threads within these (still a notch ABOVE mere "paragraphs of text"). $$ ----------------------------------------------------------------------- The following doc string example illustrates the usage of all setext constructs recognized by the gendoc tool.

Text within double asterisks are treated as bold, while single words with tilde at the front and back are rendered as ~Italic~. You can _underline_a_phrase_ but it will be rendered as bold in HTML. Placing hyperlinks is easy; just hilite_the_tag_ and at the bottom of the doc string include the address which it points to on a line by itself. New paragraphs are separated by blank lines. > And a bunch of literal text > can be specified with the left > arrow. This gets marked as

    Otherwise the text will be wrapped according to whatever 
    output formatter is used.
    
    A bulleted list is done with single asterisks thusly:
    * Lettuce
    * Onions
    * Pickles

    Extension to setext
    -------------------
    A frequent construct in python doc strings is to list ones
    keyword arguments. This made us wish for a way to specify
    a definition list so that it looks nice is html (and others).
    I propose the following. I have this working in my version.
    The double colons won't be in the output.

    item1 :: definition 1
    item2 :: definition 2
    item3 :: a rather long and involved definition for item 3
             spanning more than one line.
    item4 :: back to brevity with definition 4

    .. _hilite_the_tag http://www.python.org
    """

Notes:

The indenting inserted by python-mode for the entire doc string is
detected and processed out before setext rules are applied. So
eventhough titles for example are required to start in column one they
will if they obey the overall indenting for that doc string.

The underlines for the title and subtitle should be the same length as
the title itself.

Spaces around tokens are important (for the "* ", "> ", and " :: ")

Message-ID: <199607301616.LAA25994@darwin.rsoc.rockwell.com>

Before we get started let me comment that setext isn't our idea but
rather an adoption of an existing protocol to accomplish what we
thought was a common goal. Namely, to come up with a lightweight,
unobtusive markup standard which could be used in python doc strings.
They would be sufficient to allow automatic documentation tools to
generate nice output in several common documentation formats.
The setext protocol originated with Tony Sanders several years ago.

This can be added in the future without difficulty. Although I don't expect 
doc strings to get that elaborate. doc strings aren't intended to replace 
a formal users guide in the case of complicated applications.

The typotags have fairly rigid regular expressions and I feel it's unlikely
that they get confused. I've been using them for several weeks and it hasn't
been a difficulty at all. Time will help in refining the regex patterns.

|> 
|> OK - that was the first point - that the system you propose is not complex enough (and that's a response on almost no thought).

Something complex is exactly what we didn't want. I want to encourage 
people to use these tags. The best way of doing that is make it very easy and 
logical, otherwise people won't bother to use it.

So. That's not the intent. What's the harm in having a simple, workable system
now?

(this actually ties in with the comments on the main list recently, saying essentially "I'm not terribly keen on X, Y or Z in Python, but when I try to work round it, I get trouble - gosh, language design is difficult, and Guido is clever"). Designing a new markup language (which is what you are doing) is difficult. Designing one that can be future proof is even harder.
|> 

As the preamble states this is not an ad hoc design.  And extending the typotags
in the future shouldn't be an issue. I see no reason why adding a new format 
would break anything. Doc strings don't break, they just may not pick up 
correctly in the autogeneration tool(s) that's all. The worse thing I've
seen so far is that setext wasn't marked as expected, but that's hardly a 
crisis and is easily fixed.

|> When the company that pays me was designing its documentation comments, we were using TeX for documentation. I stronly argued that we should use TeX commands as the markup, rather than trying to grow our own - after all, there was a lot more experience in there. I lost then.
|> 
|> Nowadays, I would recommend HTML - it is simpler than Tex (and how!), easier to use, easier to `read' when looking at source code, and browsers are easier to maintain than TeX. The "everywhereness" of HTML means that most programmers will have written it (especially with so many Python apps seeming to be net related these days!). The only change I might make would be to allow blank lines to signify "
" - ie, new paragraph - since this seems reasonably intuitive - but I can argue against that almost equally well.

Setext grew out of the need to avoid the ugliness of HTML. I maintain that
HTML markup is too verbose for doc strings, and clutters the reading of them 
in code. Especially for hyperlinks. I found the reference approach setext a
far sight better that placing junk like this in doc strings. Instead, I can use doc_strings_ which flow uninterupted
by the http reference.

.. _doc_strings http://www.python.org/sigs/doc-sig/

|> 
|> And HTML seems to support the right sort of subset of markup - it shouldn't be hard to translate into n/troff, [La]TeX, Digital Runoff, whatever else one wants. Oh, and it copes with URLs just fine.

|> 
|> Is it harder to read than the setext proposal? Obviously a matter of opinion (ref the arguments about indentation in Python!) - but many of the setext things are arbitrary anyway  (why not use "*" for `emphasis', not "**"? that would fit with the normal email/ASCII convention? - oh, one can use "@" or  something for lists if one must). And you only give bold or italic - why not give us "emphasis" which is presented in a device independent manner?

Subject: [PYTHON DOC-SIG] gendoc 0.5 broken?
Message-ID: <9607301620.AA06072@max.MSC.CORNELL.EDU>

Hi all!

I'm a newcomer to Python trying to get a feel for what's available. Recently  
I came across gendoc and I thought it would fit my programming style well (use  
a perl tool right now to pull HTML docs out of my C code). Anyway, I  
installed version 0.5, but whenever I try to run gendoc it complains about a  
missing module HTMLgen:

> gendoc -f ascii -i *.py
> Traceback (innermost last):
>   File "//7/usr/local/bin/gendoc", line 125, in ?
>     import formatters
>   File "/usr/local/lib/python/ni.py", line 259, in import_module
>     m = self.get0(mname)
>
> ... lines deleted ...
>
>   File "./formatters/HTMLgenFormatter.py", line 45, in ?
>     import HTMLgen, regex, string
>   File "/usr/local/lib/python/ni.py", line 262, in import_module
>     raise ImportError, "No such module %s" % name
> ImportError: No such module HTMLgen
>

As far as I can tell (correct me if I'm wrong) I'm missing something called  
"Robin Friedrich's HTMLgen module". Where can I lay my hand on this code?

Thanks in advance for any pointers!
