Free python web objects 1.3 software for linux

HTML Objects is a Perl module library for turning HTML tags into Perl objects. HTML Objects allows Web pages to be manipulated as a data structure rather than text.

Once manipulation is done, the entire page is generated via depth-first recursion.

python-observable library lets Python developers build loosely coupled object meshes with a complete Observer/Observable implementation.

In software development literature, Observer/Observable is a software
pattern. From an Observer/Observable perspective, there are two kinds
of objects:

- objects which experience events or state changes (Observables)
- objects which need to know about other objects events (Observers)

If you have any experience with event-based programming, such as with
toolkits like GTK+ or Qt, youll be familiar with the Observer/Observable
pattern. Observer objects register themselves with the Observable object
of their interest, and when Observables experience events, these events
are relayed to the Observers.

Observer/Observable lets software developers build loosely coupled object meshes. What this means to you: your software will be more stable and easier to refactor.

This module has a complete Observer/Observable implementation. To take advantage of this module, all you have to do is:

- Make your Observable classes inherit from Observable (dont forget to call Observable.__init__(self) in the constructor)
- Make your Observer classes inherit from Observer (dont forget to call Observer.__init__(self) in the constructor)
- At runtime, for each object you want to observe, call self.observe(observable_object) in a method of your Observer object.
- In your Observable object, every time an event happens, call:
...
self.broadcastEvent("MyEventName",argument1,argument2...)
...
- In your Observer object, implement a method named: def processEvent(self,notifierObject,eventName,*args): which will receive the notifier object, an event name, and a variable number of arguments, every time broadcastEvent is called in any of the Observable objects that have been observed()

Thats it. Keep in mind that processEvent() will be invoked in the same thread context as the code which called broadcastEvent() in the Observable object. Thus, processEvent() methods should return quickly and never do blocking operations (suggested technique for coping with blocking operations: run them in a separate thread, which sleeps until a flag is raised, and raise the flag in the processEvent() method as appropriate).

python-inotify project is a Python interface to the inotify file notification system present in Linux 2.6.

Python commandsplus is a Python module that complements the existing commands module with an extra function getstatusoutputerror, which separates the standard output from the standard error and makes it easier to evaluate return status.

Python commandsplus also includes a useful function that protects a command line argument from shell metacharacters.

SPYCE is a server-side language that supports simple and efficient Python-based dynamic HTML generation, otherwise called Python Server Pages (PSP).

Those who are familiar with JSP, PHP, or ASP and like Python, should have a look at Spyce. Its modular design makes it very flexible and extensible. Spyce - Python Server Pages can also be used as a command-line utility for static text pre-processing or as a web-server proxy.

The supported adapters are:

* Fast CGI:The default Spyce integration with Apache is acheived via FastCGI, a CGI-like interface that is relatively fast, because it does not incur the large process startup overhead on each request.

* mod_python: If you really must have the fastest Spyce implementation (see the performance numbers), it is currently through an Apache module called mod_python. Spyce has been tested with mod_python version 2.7.6 (and version 3.0.3 with apache 2.0.37). You can try to find some mod_python rpms here, but in general one must compile mod_python from sources. The reason for this is because mod_python links with the Python library it finds on your system at compile time. Thus, even if you have the correct Python version installed on your system, mod_python will be using the Python library version on the system where it was compiled. Also, note that mod_python (or rather Apache) needs a Python that has been compiled without threading, so you may need to recompile Python as well for this reason. The process is not very difficult (just the usual: ./configure; make; make install dance), but hopefully someone will suggest a better route in time. In any case, make sure you can first get mod_python running on your system, if that is that is your chosen Apache integration route.

* Web server: Another fast alternative is to serve Spyce files via a proxy. This involves running Spyce in web-server mode, and configuring the main web server to forward the appropriate requests. The built-in Spyce web server can also be used to serve requests directly, but this is highly discouraged for production environments.

* CGI: Failing these alternatives you can always process requests via regular CGI, but this alternative is the slowest option and is intended primarily for those who do not have much control over their web environments.

* Command line: Lastly, one can use Spyce as a command-line tool for pre-processing Spyce pages and creating static HTML files.

python-libcommon contains Map, Set, and Graph data types for Python. It provides data types (like Graph) that can handle directed or undirected labeled graphs.
XML output is handled to describe graph structure.
Enhancements:
- The ical_generator classes were completely rewritten to be more icalendar compliant and to add day-events and the VTODO icalendar element.

Python Remote Call Module allows to transparently work with remote object in a python program.
To make this possible a kind of peer-to-peer design is used. Servers can be created explictly, as can clients by explicitly connecting to a server. If a client needs to have a server, e.g. so a reference to a local object can be passed to a remote destination, it is instantiated as needed.
Clients can have multiple connections. New connections are created when needed, e.g. when a remote reference to a new server is recieved.
WARNING:
This module is still in its experimental phase, so it is kind of usable, but an awful lot of bugs is still in it, and quite a few parts are not coded yet, others arent even designed yet.
Therefor lots of changes and outdated documentation should be expected.
Enhancements:
- All previous stub objects have been replaced by a single stub object which uses on-demand retrieval of attributes of remote objects.
- This way, the behavior of the stub object is much more flexible and smoother.
- A first draft of an authentication framework has been implemented so PyRCall can support many different authentication methods.
- Support for username/password-based authentication has been implemented.
