Added getLevel() functions to Scholar.Object and Scholar.Folder -- save() and setPosition() not yet updated
Updated sample data to include levels
Added orderIndex (from treeOrder table, now) back into Scholar.Object data
New Scholar.Objects method for treeView: getTreeRows() -- returns mixed array of all Folder and Object objects in the proper order, type testable with instanceof (e.g. if (obj instanceof Scholar.Folder))
Scholar.Objects.get() and getAll() return arrays hashed by objectID again, since they're no longer used directly by treeView
Scholar.Objects.get() now returns the object directly if only one argument and scalar (i.e. one id)
Updated schema and sample data to handle folder ordering
Added include.js for use in non-browser.xul windows to bring in the SCHOLAR_CONFIG and Scholar objects
Adjusted sidebar to use shared object
Added test line (displayable by clicking "Hello, World" before and after sidebar load to demonstrate cross-window access
I also started implementing some of the localization. There is a lot to do still, and I am still learning a lot of the Firefox extension technologies (XUL, adv. Javascript, etc.) but things are going great.
Fixed object retrieval queries to use orderIndex is 0 rather than 1, since that's the default now
Scholar_Objects.getAll() now uses loaded.push() rather than loaded[objectID], since _for (objectID in objects)_ isn't an option with treeview
Scholar_Object.getField() now returns an empty string rather than false for empty values
Added some new core functions:
- Scholar.varDump(), after PHP's var_dump()
- Scholar.flattenArguments(), to flatten mixed array/literal argument lists into a single array
- Scholar.join() -- a version of join() that operates externally, for use on, for example, the arguments object (safer than extending Object)
- Scholar.Hash, a slightly smarter associative array -- not perfect, but brings a proper length property and a few convenience methods (and allows for other additions) -- should probably be limited to places where the length property or other additional additions are needed, since its use is a little non-standard (e.g. you have to remember to do _for (i in arr.items)_ rather than just _for (i in arr)_, to use set(), etc.)
Moved schema file out of chrome and removed XML tags, since it will no longer be accessed by XMLHTTP
Changed schema updater to use XPCOM components rather than XMLHTTP
Converted DB class to a singleton named Scholar_DB
Scholar_DB.query() now returns associative array similar to mysql_fetch_assoc() for SELECT statements rather than a mozIStorageStatementWrapper -- the mozStorage executeDataSet() function doesn't work yet, so we do it this way
Added DB functions:
- beginTransaction(), commitTransaction(), rollbackTransaction()
- columnQuery() -- one column, multiple rows, returned as array indexed by row
- getColumns() and getColumnHash
DB query functions can now handle bind parameters passed as an array of object literals: e.g. [{'int':2},{'string':'foobar'}]
valueQuery() now returns an int for COUNT(*) queries, so the result can be tested without a "0" being true
Changed _initializeSchema to drop existing tables before creating new ones, hacked with try/catch until DROP TABLE IF EXISTS works with the mozStorage extension (it's already in the latest SQLite release)
Added DB_REBUILD config flag to manually trigger schema regeneration
Added debug logging at level 5 for all SQL queries
Updated sample data
