tiddlywebplugins.diststore 0.8

Use multiple stores in the same TiddlyWeb instance.

A TiddlyWeb store that makes it possible to store some content in different stores, based on rules defined in tiddlywebconfig.py.

The rules are regular expressions which match the name of a bag. When a tiddler or bag is accessed (for read or write) if the name of the bag matches a regular expression in the store's "extras" dictionary, the store named in the value is responsible for the entity being accessed. Otherwise the store named in "main" is used.

This is an experimental store, but it is being reliably used in production with the http://www.wiki-data.com/ website. In that service, the main collection of tiddler data is kept in one highly optimized bag using the mappingsql store, while users and other system data are stored in a text store. Here's the relevant config:

'server_store': ['tiddlywebplugins.diststore', {

'main': ['text', {'store_root': 'store'}], 'extras': [

System Message: ERROR/3 (<string>, line 19)

Unexpected indentation.

(r'^example$', ['mappingsql',

{'db_config':

'mysql://example@localhost/example?charset=utf8'}]),

System Message: WARNING/2 (<string>, line 22)

Block quote ends without a blank line; unexpected unindent.

],

System Message: WARNING/2 (<string>, line 23)

Definition list ends without a blank line; unexpected unindent.

}],

To use this plugin you must modify tiddlywebconfig.py to set the 'server_store' item. Do not add 'tiddlywebplugins.diststore' to 'system_plugins' or 'twanager_plugins'.
