Then shifts all reference starting from the reference, using the shift amount (i.e. if there are 50 resistors, R50 ->R54, R49 ->R53, … R43 -> R47)
I other words, a plugin able to “insert” a number of “free” slots, without having to do it manually.
Does it exist ? If not how difficult would it be to develop it ?
In version 5 Eeschema, the schematic editor, doesn’t have a plugin interface. You have to write something which manipulates the file directly. How difficult? Just read the schematic files and compare with your programming ability
I’m with eelik.
Eeschema is a pretty simple text based format and you can probably do this with a text editor that has some scripting capabilities, or any scripting language that is good with handling text.
