* scripting: added service and controller for scripting
* scripting: have got prompts working
Scripts are now running in a separate go-routine. When a prompt is encountered, the
script is paused and the user is prompted for input. This means that the script no
longer needs to worry about synchronisation issues.
* scripting: started working on the session methods
* scripting: added methods to get items and attributes
* scripting: have got loading of scripts working
These act more like plugins and allow defining new commands.
* scripting: have got script scheduling working
Scripts are now executed on a dedicated goroutine and only one script can run at any one time.
* scripting: added session.set_result_set(rs)
* scripting: upgraded tamarin to 0.14
* scripting: started working on set_value
* tamarin: replaced ad-hoc path with query expressions
* scripting: changed value() and set_value() to attr() and set_attr()
Also added 'delete_attr()'
* scripting: added os.exec()
This method is controlled by permissions which govern whether shellouts are allowed
Also fixed a resizing bug with the status window which was not properly handling status messages with newlines
* scripting: added the session.current_item() method
* scripting: added placeholders to query expressions
* scripting: added support for setting and deleteing items with placeholders
Also refactored the dot AST type so that it support placeholders. Placeholders are not yet supported
for subrefs yet, they need to be identifiers.
* scripting: made setting the result-set push the current result-set to the backstack
* scripting: started working on byte encoding of attribute values
* scripting: finished attrcodec
* scripting: integrated codec into expression
* scripting: added equals and hashcode to queryexpr
This finally finishes the work required to store queries in the backstack
* scripting: fixed some bugs with the back-stack
* scripting: upgraded Tamarin
* scripting: removed some commented out code
- Most aspects of scans and queries can now be represented using the expression language
- All constructs of the expression language can be used to evaluate items
- Fixed the gaps in conjunctions, disjunctions, and equality operator for expression value evaluation.
- Fixed the issue in which '^=' was treated as two separate tokens, it's now a single token.
Added a new popup to modify the columns of the table. With this new popup, the user can:
- Show and hide columns
- Move columns around
- Add new columns which are derived from the value of an expression
- Delete columns
Also got the overlay mechanisms working.
Augmented expressions so that queries that can be executed as queries on DynamoDB can be done so.
Also added an IR tree which is a simplified representation of the AST and will be used to plan the query.
