Stage Changes
- Added context menus:
- Right-clicking the stage launches context menu at that point with several options:
- 'Search by ID' allows the user to serach for a specific STE by its ID
- 'Show All Nodes' reveals every node that may have been hidden
- 'Toggle Editor Mode' switches to/from Editor Mode (see below for info)
- 'Reset Camera' doubles the functionality of the normal 'Reset Camera' button (both now reset rotation as well)
- Right-clicking a node displays some info and options:
- Shows an STE's Id, symbol set, start type (if applicable) and report code (if applicable)
- 'Show/Hide Children' will toggle the visibility of all descendants of the clicked node
- 'Solo Children' will hide all nodes on graph that are not descendants of the clicked node
- '- Print Node Data -' outputs the node JSON data to the browser's console (useful for debugging)
- Right-clicking the stage launches context menu at that point with several options:
- Added 'View Graph Legend' button to 'Graph Settings' tab
- Displays small popup window with color representations of different states of STEs
- Automatically updates colors based on global settings file (see below about global settings)
- Added context menus:
-
Added "Editor Mode"
- Can be switched in/out of by right-clicking the stage and selecting 'Toggle Editor Mode'
- Allows the user to move, create, delete, or change STEs and their connections
- STEs can be moved around by clicking and dragging
- Multiple STEs can be selected at once in a number of ways:
- 'Lasso Tool' allows the user to draw a shape around all nodes they wish to select
- 'Box Select' selects all nodes within a rectangular region drawn by the user
- Pressing the spacebar then 'A' selects all nodes
- Pressing the spacebar then 'U' unselects all nodes
- Pressing the spacebar then 'E' selects the immediate neighbors of all selected nodes
- Pressing the spacebar then left clicking selects the clicked node in addition
- Right-clicking the stage provides a number of options:
- 'Add STE' shows a popup that allows the user to create a new STE that is added to the automata where the user clicks
- 'Show All Nodes' displays all previously hidden nodes
- 'Toggle Editor Mode' exits the editor
- 'Reset Camera' resets the camera view
- '- Print All Node Data -' outputs all node JSON data to the browser's console (useful for debugging)
- Right-clicking an STE also provides a number of options:
- First displays the same data as shown in the normal mode
- 'Add Outgoing Connection' adds a connection from the current STE to the next clicked one
- Clicking the current STE creates a self-loop
- Clicking the stage will not add a connection
- 'Change Data' provides popup similar to creation popup and allows user to change any data about an STE
- 'Delete STE' removes the STE from the automata and all related connections
- 'Print Node Data' has similar function from normal mode
- Right-clicking a connection provides a few options:
- 'Selected Connected STEs' selects the STEs on either ends of the connecting edge
- 'Remove Edge' deletes the connection from the automata
- 'Save Automata File' downloads a .anml file containing the data of the current automata displayed
- 'Save Graph Data' downloads a .json file containing the position data of all nodes and edges
- This is useful when a preferable layout has been achieved and can be used when reloading automata
-
Added 'Positioning Method' to automata constructor settings
- Allows user to select different positioning method (more can be added in future)
- Custom positioning allows user to upload JSON graph file that is applied to layout
- This file must match all IDs of STEs and connections properly or errors will likely occur
- This file can be generated in editor mode by clicking 'Save Graph Data' button after editing
-
Added global settings file for visual customization
- js/ViewerSettings.js contains intuitively named properties for editing some default visual settings
- All changes are reflected after page reload and graph legend also displays updated color scheme
-
Smaller changes:
- Added glyphs to buttons for more intuitive user experience
- Added rotation slider to 'Graph Settings' to rotate camera
- URL will automatically update to reflect when user loads an ANMLZoo file with certain optimizations
- Removed ability to upload JSON file as automata because JSON does not actually construct an automata
- Properly implemented self-loops in renderers!
- Catch all VASim errors so the server no longer crashes if problem occurs in constucting automata
- Changed 'Stop on Report' checkbox to selector
- 'Stop on cycle' allows user to enter cycle # to stop simulation on
- Added cycle count to 'Reporting STE' popover on character stream
- Added more metadata to STE label
- Changed label code to handle displaying multiple lines of info
- By default, all nodes on will show the STE's id and symbol set (ss)
- Reporting STEs and start STEs will display report code and start type, respectively
- Changed function on clicking STE to show all descendants instead of immediately connected nodes
- Character stream now shows all reporting steps on cache load instead of when passed
- Changed 'Automata Construction Options' menu:
- Removed 'Local Optimization'
- Added optional 'Fan-In/Fan-Out Limit'
- This changes the format for GET data
- New format is
?a=AutomataName&o=2bitOptCode&fi=fanInLimit&fo=fanOutLimit ?a=Brill&o=11&fo=2would load Brill with global optimization, remove OR gates, and have a fan out limit of 2
- New format is
- Changed 'Graph Settings' tab:
- Removed 'Arrow Size' slider because WebGL renderer does not display changes in arrow size
- Changed 'Graph Width' slider to 'Width/Height Ratio' due to Sigma autoscaling behavior
- Revisited sliders for node size, edge thickness and graph width to scale geometrically with greater ranges
- Improved interactivity of character stream
- Greyed out characters are not in the cache and therefore cannot be reached (unless simulating forward)
- Characters in the cache can be clicked on and the corresponding simulation step will be shown
- If a user jumps past a reporting step, the character will still turn purple in the character stream
- URL can handle GET data to send pre-optimized ANMLZoo automata in the following format:
?a=AutomataName&o=3bitOptCode- Example: appending
?a=Brill&o=100will preload Brill with a global optimization (other bits are local opt/remove OR gates)
- Example: appending
- Added new features to Simulation Tools:
- 'Cycle Index' counter displays current cycle count
- 'Stop on Report' checkbox will stop a simulation that is being played if it reaches a reporting step
- 'Download Report Record' button will save a file called 'reports.txt' that contains information about all reporting STEs for all previously and currently cached steps
- Added 'Type Input' feature near input upload to manually enter an input stream
- Fixed bugs with uploading new files after starting simulation
- Added "Play Speed" range slider to add delay to between simulation steps
- 'Fastest' adds no delay; 'Slowest' adds 2 seconds between steps
- Moved all range slider handling to Javascript so it is responsive without server interaction
- Removed unneeded functions from VASimVis.cc
- Implemented new cache system code
- Generates 100 graphs immediately
- Recaches when simulation index is 25 from end of cache
- Caches 100 new steps, then removes steps from beginning until 25 from index
- Moved entire cache system to JavaScript
- This allows simulation to proceed much faster due to connectionless progression
- Once cache is generated, simulation manipulation could occur even if server crashed
- JavaScript sends signal to C++ to generate new cache at specific threshold
- Simulation can now run uninterrupted (even while generating new cache)
- First major upload -- see usability features in README.md
