I have a large project that is getting complex, and I would like to
print the docstrings without importing the modules. The only Python
utility I could find references is apparently defunct and hasn't been
updated in 4 years.
I don't care how spartan the output is - it could look exactly like
python's internal docstrings, for all I care. It would be a nice added
bonus if it printed to HTML, but not if it greatly increased the
interface complexity. But I don't want to have to import the module to
run it! I want to just have a function that I pass a list of filenames
to.
Does anyone know of such a utility?
No, but here's one I just created (not tested very much):
----< docstr2html.py >--------------------------------------------
# docstr2html.py
"""
Prints html to display docstrings of modules specified on command line,
with optional globbing and html page title default override.
Usage: [python] docstr2html.py [-title "some title"] (file_pattern)+
Note: If redirecting stdout, some windows versions require [python] to be explicit.

s = s.replace(">", ">")

s = s.replace('"', """)
return s

Running it (first to get the help response, which is just the doc string ;-)
[20:04] C:\pywk\ut>python docstr2html.py
Prints html to display docstrings of modules specified on command line,
with optional globbing and html page title default override.
Usage: [python] docstr2html.py [-title "some title"] (file_pattern)+
Note: If redirecting stdout, some windows versions require [python] to be explicit.
Then generating the html:
[20:04] C:\pywk\ut>python docstr2html.py docstr2html.py
<html><head><title>doc strings as of Sun Jul 31 20:04:55 2005</title></head><body>
<br>
<table border="2">
<tr bgcolor="#99FFFF"><th>C:\pywk\ut\docstr2html.py</th></tr>
<tr bgcolor="#99FF99"><td><pre>
Prints html to display docstrings of modules specified on command line,
with optional globbing and html page title default override.
Usage: [python] docstr2html.py [-title "some title"] (file_pattern)+
Note: If redirecting stdout, some windows versions require [python] to be explicit.
</pre></td></tr>
</table>
</body></html>
You can use file specs like someplace\*.py (wild cards) and it should do all the files
and put it all in tables in the html output. Note that is uses all file specs as patterns,
and ignores without complaint any that don't match anything.
