Reading gEDA schematic/symbol files.
The gEDA file format is a space separated list of characters and numbers in plain ASCII. The meaning of each item is described in the file format documentation which can be found in doc/geda/file_format_spec or here.

| def xorn.geda.plainread.sscanf | ( | s, | |
| fmt | |||
| ) |
Parse a string of space-separated values.
This is a mock-up version of the standard sscanf(3). The format string must consist of zero or more tokens separated by a space, optionally followed by a newline character. The format string must exactly match this pattern. Only the tokens %c, %d, %s, and %u are allowed.
| ValueError | if the string does not match the format |
| ValueError | if an invalid format token is passed |
