How to open a library from within an ULP?

Joop14

Hello everybody.

 

I'm writing an ULP that runs from within a schematic context. The schematic editor and board editor are opened, the library editor is closed (not active).

From within a running ULP, I take the library name from a part of the schematic.

Knowing the name of that library, I would like to access that library.

 

My question is, how do I open a library(context) from within an ULP while the library editor is closed?

 

Best Regards,

    Hello Joop,

     

    > My question is, how do I open a library(context) from within an ULP

    while the library editor is closed?

     

    I have used this sequence to append the open command to the script:

     

       sprintf(h, "OPEN '%s';\n", library_filename);

       cmd += h;

     

    then to edit a package, for example:

       sprintf(h, "EDIT %s.PAC;\nGRID MM;\nSET WIRE_BEND 2;\n", pac_name);

       cmd += h;

     

    And for closing:

       sprintf(h, "WRITE;\nCLOSE;\n");

       cmd += h;

     

    Regards,

    Neil

    Thanks Neil.

     

    I think I have to clarify better what I want to do.

    I want to access the properties of a deviceset within a library. Only for this reason I need to open (temporary) a library, read some properties and then close it.

    What I want to write is an ULP that checks for and reports about any differences between parts/packages in a schematic/board design and the respective parts in the libraries.

    Because Cadsoft is not very eager to implement this, I would like to do this in an ULP.

    It has been discussed here: http://www.element14.com/community/thread/34204/l/eagle-version-66-released

     

    However, maybe it's better not to write an ULP but a normal program in C combined with an XML-parser...
