I want to be able to write a script to mass change all the libraries that a project depends on in order to make better B.O.M.  Bill Of Materials.  The following script lists the libraries in the project directory.  It writes the names of the libraries with full path to Read more…

When you need to know the path of the project you are running the ULP within the following code snippet is useful. string get_project_path() {   if (board)     board(B)     return(filedir(B.name));   if (schematic) schematic(B) return(filedir(S.name));   if (library)   library(B)   return(filedir(L.name)); } string Directory; Directory Read more…

You select a device in an opened library for edit by using this syntax:  edit deviceset Value is set to an active editable value with the syntax:  value on Thus on a meta level this script is going to do the following things for each part in the library: write the open device Read more…

For my BOM ULP I want to use attribute fields that you can see here.  To do this I need to know how to read an attribute.  The code snippet below does that.  The test attribute name is FUDGE and the test value is VANILLA.   To read attributes you Read more…

Now it is time to build on the previous examples.  This example does the following: Get the path of the User Language Program (ULP) It loops through all the parts As it loops it appends the part name to a file dlgMessageBox("Do you want to count the parts?","Yes","No","Maybe");     Read more…

If you want to alter anything on the schematic with a User Language Program you will need to output to a command line script file.   The most common thing to do is write it to the same directory that the ULP is in.  To do that you are going Read more…

Script functions required Need the script syntax to change a part value.  The command line to issue to change a part value is: value refdes value.  And example would be to change R5's value to 100 you would issue the command:  value r5 100 Need to add attribute fields to Read more…

This program demonstrates how you access the Schematic object with an Eagle PCB User Language Program – ULP. dlgMessageBox("Do you want to count the parts?","Yes","No","Maybe");                       //opens a dialog box: no matter what you answer it will count the parts. Read more…
