Abstract:
|
|
This example shows how to read the custom data of an .lpi file and
|
|
how to change it. The .lpi file is given as first command line parameter.
|
|
|
|
For example:
|
|
./lpicustomdata lpicustomdata.lpi
|
|
|
|
This will show the old custom data, change a value and save it.
|
|
If there was no custom data in the .lpi file, there will be no output.
|
|
|
|
Important:
|
|
The IDE does not read the .lpi file if it changed on disk.
|
|
If you add custom data, make sure the IDE has not this project open.
