+ PySourceColor.py
+
+----------------------------------------------------------------------------
+
+ A python source to colorized html/css/xhtml converter.
+ Hacked by M.E.Farmer Jr. 2004, 2005
+ Python license
+
+----------------------------------------------------------------------------
+
+ - HTML markup does not create w3c valid html, but it works on every
+ browser i've tried so far.(I.E.,Mozilla/Firefox,Opera,Konqueror,wxHTML).
+ - CSS markup is w3c validated html 4.01 strict,
+ but will not render correctly on all browsers.
+ - XHTML markup is w3c validated xhtml 1.0 strict,
+ like html 4.01, will not render correctly on all browsers.
+
+----------------------------------------------------------------------------
+
+Features:
+
+ -Three types of markup:
+ html (default)
+ css/html 4.01 strict
+ xhtml 1.0 strict
+
+ -Can tokenize and colorize:
+ 12 types of strings
+ 2 comment types
+ numbers
+ operators
+ brackets
+ math operators
+ class / name
+ def / name
+ decorator / name
+ keywords
+ arguments class/def/decorator
+ linenumbers
+ names
+ text
+
+ -Eight colorschemes built-in:
+ null
+ mono
+ lite (default)
+ dark
+ dark2
+ idle
+ viewcvs
+ pythonwin
+
+ -Header and footer
+ set to '' for builtin header / footer.
+ give path to a file containing the html
+ you want added as header or footer.
+
+ -Arbitrary text and html
+ html markup converts all to raw (TEXT token)
+ #@# for raw -> send raw text.
+ #$# for span -> inline html and text.
+ #%# for div -> block level html and text.
+
+ -Linenumbers
+ Supports all styles. New token is called LINENUMBER.
+ Defaults to NAME if not defined.
+
+ Style options
+
+ -ALL markups support these text styles:
+ b = bold
+ i = italic
+ u = underline
+ -CSS and XHTML has limited support for borders:
+ HTML markup functions will ignore these.
+ Optional: Border color in RGB hex
+ Defaults to the text forecolor.
+ #rrggbb = border color
+ Border size:
+ l = thick
+ m = medium
+ t = thin
+ Border type:
+ - = dashed
+ . = dotted
+ s = solid
+ d = double
+ g = groove
+ r = ridge
+ n = inset
+ o = outset
+ You can specify multiple sides,
+ they will all use the same style.
+ Optional: Default is full border.
+ v = bottom
+ < = left
+ > = right
+ ^ = top
+ NOTE: Specify the styles you want.
+ The markups will ignore unsupported styles
+ Also note not all browsers can show these options
+
+ -All tokens default to NAME if not defined
+ so the only absolutely critical ones to define are:
+ NAME, ERRORTOKEN, PAGEBACKGROUND
+

+ -----------------------------------------------------------------------------
+ PySourceColor.py ver: %s
+ -----------------------------------------------------------------------------
+ Module summary:
+ This module is designed to colorize python source code.
+ Input--->python source
+ Output-->colorized (html, html4.01/css, xhtml1.0)
+ Standalone:
+ This module will work from the command line with options.
+ This module will work with redirected stdio.
+ Imported:
+ This module can be imported and used directly in your code.
+ -----------------------------------------------------------------------------
+ Command line options:
+ -h, --help
+ Optional-> Display this help message.
+ -t, --test
+ Optional-> Will ignore all others flags but --profile
+ test all schemes and markup combinations
+ -p, --profile
+ Optional-> Works only with --test or -t
+ runs profile.py and makes the test work in quiet mode.
+ -i, --in, --input
+ Optional-> If you give input on stdin.
+ Use any of these for the current dir (.,cwd)
+ Input can be file or dir.
+ Input from stdin use one of the following (-,stdin)
+ If stdin is used as input stdout is output unless specified.
+ -o, --out, --output
+ Optional-> output dir for the colorized source.
+ default: output dir is the input dir.
+ To output html to stdout use one of the following (-,stdout)
+ Stdout can be used without stdin if you give a file as input.
+ -c, --color
+ Optional-> null, mono, dark, dark2, lite, idle, pythonwin, viewcvs
+ default: dark
+ -s, --show
+ Optional-> Show page after creation.
+ default: no show
+ -m, --markup
+ Optional-> html, css, xhtml
+ css, xhtml also support external stylesheets (-e,--external)
+ default: HTML
+ -e, --external
+ Optional-> use with css, xhtml
+ Writes an style sheet instead of embedding it in the page
+ saves it as pystyle.css in the same directory.
+ html markup will silently ignore this flag.
+ -H, --header
+ Opional-> add a page header to the top of the output
+ -H
+ Builtin header (name,date,hrule)
+ --header
+ You must specify a filename.
+ The header file must be valid html
+ and must handle its own font colors.
+ ex. --header c:/tmp/header.txt
+ -F, --footer
+ Opional-> add a page footer to the bottom of the output
+ -F
+ Builtin footer (hrule,name,date)
+ --footer
+ You must specify a filename.
+ The footer file must be valid html
+ and must handle its own font colors.
+ ex. --footer c:/tmp/footer.txt
+ -l, --linenumbers
+ Optional-> default is no linenumbers
+ Adds line numbers to the start of each line in the code.
+ --convertpage
+ Given a webpage that has code embedded in tags it will
+ convert embedded code to colorized html.
+ (see pageconvert for details)
+ -----------------------------------------------------------------------------
+ Option usage:
+ # Test and show pages
+ python PySourceColor.py -t -s
+ # Test and only show profile results
+ python PySourceColor.py -t -p
+ # Colorize all .py,.pyw files in cwdir you can also use: (.,cwd)
+ python PySourceColor.py -i .
+ # Using long options w/ =
+ python PySourceColor.py --in=c:/myDir/my.py --color=lite --show
+ # Using short options w/out =
+ python PySourceColor.py -i c:/myDir/ -c idle -m css -e
+ # Using any mix
+ python PySourceColor.py --in . -o=c:/myDir --show
+ # Place a custom header on your files
+ python PySourceColor.py -i . -o c:/tmp -m xhtml --header c:/header.txt
+ -----------------------------------------------------------------------------
+ Stdio usage:
+ # Stdio using no options
+ python PySourceColor.py < c:/MyFile.py > c:/tmp/MyFile.html
+ # Using stdin alone automatically uses stdout for output: (stdin,-)
+ python PySourceColor.py -i- < c:/MyFile.py > c:/tmp/myfile.html
+ # Stdout can also be written to directly from a file instead of stdin
+ python PySourceColor.py -i c:/MyFile.py -m css -o- > c:/tmp/myfile.html
+ # Stdin can be used as input , but output can still be specified
+ python PySourceColor.py -i- -o c:/pydoc.py.html -s < c:/Python22/my.py

+Date, Time, and Timespan Parsing Utilities
+
+This module contains parsing support to create "human friendly"
+``datetime`` object parsing. The explicit goal of these routines is
+to provide a multi-format date/time support not unlike that found in
+Microsoft Excel. In most approaches, the input is very "strict" to
+prevent errors -- however, this approach is much more liberal since we
+are assuming the user-interface is parroting back the normalized value
+and thus the user has immediate feedback if the data is not typed in
+correctly.
+
+ ``parse_date`` and ``normalize_date``
+
+ These functions take a value like '9 jan 2007' and returns either an
+ ``date`` object, or an ISO 8601 formatted date value such
+ as '2007-01-09'. There is an option to provide an Oracle database
+ style output as well, ``09 JAN 2007``, but this is not the default.
+
+ This module always treats '/' delimiters as using US date order
+ (since the author's clients are US based), hence '1/9/2007' is
+ January 9th. Since this module treats the '-' as following
+ European order this supports both modes of data-entry; together
+ with immediate parroting back the result to the screen, the author
+ has found this approach to work well in pratice.
+
+ ``parse_time`` and ``normalize_time``
+
+ These functions take a value like '1 pm' and returns either an
+ ``time`` object, or an ISO 8601 formatted 24h clock time
+ such as '13:00'. There is an option to provide for US style time
+ values, '1:00 PM', however this is not the default.
+
+ ``parse_datetime`` and ``normalize_datetime``
+
+ These functions take a value like '9 jan 2007 at 1 pm' and returns
+ either an ``datetime`` object, or an ISO 8601 formatted
+ return (without the T) such as '2007-01-09 13:00'. There is an
+ option to provide for Oracle / US style, '09 JAN 2007 @ 1:00 PM',
+ however this is not the default.
+
+ ``parse_delta`` and ``normalize_delta``
+
+ These functions take a value like '1h 15m' and returns either an
+ ``timedelta`` object, or an 2-decimal fixed-point
+ numerical value in hours, such as '1.25'. The rationale is to
+ support meeting or time-billing lengths, not to be an accurate
+ representation in mili-seconds. As such not all valid
+ ``timedelta`` values will have a normalized representation.

+ Passing an integer or long means passing an IPv4-address that's already

+ an address where this conversion still has to be done. A string
+ address may be in the following formats:
+
+ - 1.2.3.4 - a plain address, interpreted as a single address

+the template (for errors) and a default namespace. Then (like
+``string.Template``) you can call the ``tmpl.substitute(**kw)``
+method to make a substitution (or ``tmpl.substitute(a_dict)``).
+
+``sub(content, **kw)`` substitutes the template immediately. You
+can use ``__name='tmpl.html'`` to set the name of the template.
+
+If there are syntax errors ``TemplateError`` will be raised.

+================

+:author: Ian Bicking
+:date: 12 Jul 2004
+
+Multi-threaded printing; allows the output produced via print to be
+separated according to the thread.
+
+To use this, you must install the catcher, like::
+
+ threadedprint.install()
+
+The installation optionally takes one of three parameters:
+
+default
+ The default destination for print statements (e.g., ``sys.stdout``).
+factory
+ A function that will produce the stream for a thread, given the
+ thread's name.
+paramwriter
+ Instead of writing to a file-like stream, this function will be
+ called like ``paramwriter(thread_name, text)`` for every write.
+
+The thread name is the value returned by
+``threading.currentThread().getName()``, a string (typically something
+like Thread-N).
+
+You can also submit file-like objects for specific threads, which will
+override any of these parameters. To do this, call ``register(stream,
+[threadName])``. ``threadName`` is optional, and if not provided the
+stream will be registered for the current thread.
+
+If no specific stream is registered for a thread, and no default has
+been provided, then an error will occur when anything is written to
+``sys.stdout`` (or printed).
+
+Note: the stream's ``write`` method will be called in the thread the
+text came from, so you should consider thread safety, especially if
+multiple threads share the same writer.
+
+Note: if you want access to the original standard out, use
+``sys.__stdout__``.
+
+You may also uninstall this, via::
+
+ threadedprint.uninstall()
+
+TODO
+----
+
+* Something with ``sys.stderr``.
+* Some default handlers. Maybe something that hooks into `logging`.
+* Possibly cache the results of ``factory`` calls. This would be a
+ semantic change.
