[edit] Advanced scripting in the server

HynekPetrak 09:02, 26 April 2006 (CEST)

[edit] Description

As of current version (1.10) the lintouch, plugins can't access variables of each other. It is not possible, for example, from Lua plugin read the variables received over a Modbus/TCP connection. If we add a possibility of a read-only access for real-values and eventualy a read-write access to requested values of other plugins, it opens a wide range of new possibilities like:

  • extract bits/bytes from bigger variables
  • calculations on variables
  • unit conversions
  • variable monitoring with
  • etc.

[edit] An Example

Modbus plugin has a variable "HEIGHT_FT" which is a height of something in feets. The height in feet is fetched over Modbus/TCP form some device. The Lua plugin has a variable "HEIGHT_M" which represents the same height of something but in meters. The Lua plugin with following code makes the magic: 

while should_run() do
   
    height_in_feet = global_variables.modbus.HEIGHT_FT

    height_in_m = height_in_feet * 0.33 

    -- send to lintouch the new time
    set_real_value( variables.HEIGHT_M, height_in_m )
   
   -- sync results back to lintouch
   sync_real_values()

   sleep( 0.01 * 1000 * 1000 )

end

[edit] Comments

Any word on this feature request. I would also find this very helpful.

[edit] Password protection for project files

Nelson Mambre 26 April 2006

[edit] Description

Lintouch could offer the possibility to protect a project file, with different protection levels. This way we can control the way the end user (the client) can access the project content.

[edit] Justification

  • To prevent the end-user to modify the project, sometimes too much power for an inexperienced user is dangerous.
  • Maybe you have a Lua script with some control logic that you don't want everybody to see.
  • ...

[edit] Desired Features

  • Possibility to lock whole project or parts of it
  • Protection of scripts, conections, variables, layout separately/independently
  • Password for editing and for running the project.
  • Possibility to lock some scripts, leaving others open for the user to modify.
  • ...

[edit] Implementation Considerations

  • A project file is basically a zip file, so it could be possible to use the same mechanism to password protect (parts of) the file.
  • Most probably a first implementation could be just locking the whole project. (Seems to be easier)
  • Check if it is possible to assign different passwords for normal zip files, and also if possible to protect part of the content in the zip file.
  • If not possible to create different passwords for a single zip file, maybe a workaround could be a password for the whole file, and a second (protected) zip file in the project containing lists of other passwords
  • ...

[edit] Comments

(Please add your comments here, or if you can place it in the above sections, you can add your name to it)

[edit] Miscelaneous user interface modifications and features requests

Felipe Ledesma 27 April 2006

[edit] Description

It would be nice to have:

  • Locking objects
  • Pop-up panels
  • Link to panels for the button widgets
  • Mouse over behaviours
  • Active/Inactive for SVG images

Other issues not related to UI:

  • When you load an app that has a plugin that isn't installed you get kicked out, and get a segmentation fault.

[edit] Justification

  • To have a more flexible user interface.
  • It is easier and faster to develop the panels.
