# TODO

- [ ] **MAJOR** Implement configuration manager:
  - configuration is a set of signals (that can be organized in group and subgroup) that are used to configure a system or a sub system
  - with configuration manager user should be able to:
    - Define and manage configuration sets: delete (keep server side copy of deleted config), create (specifying default to parameters, mandatory, optional etc), edit (with versioning git style) and compare set
      - user can fork an existing config instance to create a new one
      - user can compare two instances: show unified diff or side by side diff
      - etc...
    - Create, delete (keep server cache), edit (git style versioning) and compare configuration instances: meaning set actual value to a configuration set
      - user can fork an existing config instance to create a new one
      - user can compare two instances: show unified diff or side by side diff
      - etc...
  - [x] user can apply and save configuration instances from manager
  - [ ] in logic editor and control loop add nodes to read/write/create/apply config instances
  - [x] support for all supported types (number, bools, enums, arrays, string etc)
  - [x] ux elements for config set
    - [x] the configuration editor should automatically get type and info from signal when possible (type is read-only, auto-derived from the bound signal)
    - [x] a slick tree drag and drop editor to order elements and organize in group and sub-groups
    - [x] possibility to customise unit, max, min etc
    - [x] export / import a config set as JSON
    - [x] full-screen config window
  - [x] ux elements for config instances:
    - automatically use the correct setting widget depending on the type (e.g. combo for enum, nubmer input for number):
      - for arrays: import csv option, display points as mini plot (+ open dialog plot with more info), manual enter points via table like interface
    - automatically fill with default or existing values (when forking an existing instance)
    - explicity show errors/missing info and give additional info on hover
  - [ ] add advanced validation / transformation framework to configurations using custom CUE rules:
    - backend should run validation / transformation rules
    - user can create/edit/delete/compare rules from webui:
      - integrate syntax highlight
      - integrate autocomplete for signals names and cue grammars
      - integrate cue lsp
    - when validation fail error should be propagated to user in the webui
    - all action should be tracked via history management and audit
- [ ] Improve UX:
  - [x] Synthetic editor:
    - [x] color code the node link by type
    - [x] hover on a block in error should show the reason
    - [x] add proper array functionality
    - [x] add shortcut to add Signals (S) and nodes (N) with HUD
  - [ ] Panels:
    - [x] in view mode the widgets should have no border/bg but blend with background
    - [ ] add widgets such as toggle switch, table and other industrial hmi widgets
    - [ ] add container widgets: labelled/title pane, tab panes, collapsable panes etc
  - [ ] plot pane:
    - add toolbar
  - [ ] clean ui:
    - create small statusbar where connection widget and other status related info will be placed
    - group advanced items (audit/control loops/config manager etc) in a tool menu or something similar to not fill the toolbar
    - make the toolbar as clean as possible
- [ ] Logic editor:
  - add full support to local array values: dynamic, dynamic but capped max, fixed size etc:
    - array functions should work with new local array
- [ ] Control loop:
  - add full support to server side array values
- [ ] Implement git style versioning for: synthetic variable, panels, control logic:
  - possibility to fork any version
  - click to view the version
  - possibility to view graphical diff between versions (side by side or unified diff)
  - simple slick versioning pane:
    - vertical tree like
    - each version represented by a circle
    - active (the one currently view/edited) version has circle bigger then rest
    - selected (the one that will be executed/showed by user) version has circle full, not active only border
    - unsaved / new version appear with connection line dashed
- [ ] Implement admin pane: create / manage groups, set users permits, manage auditors etc
- [ ] Implement new datasources:
  - [ ] Finalize alarm service
  - [ ] modbus tcp
  - [ ] scpi tcp
  - [ ] udp? other?
- [ ] **MAJOR** Implement proper distributed server side nodes to balance load and have redundancy (if a node is not available anymore all its clients migrate seamelessly to another)
