Arguments

input

file - ASCII file to be imported. Path to a file.

format

enum of ("point", "standard") - Input file format. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

separator

string - Field separator. String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

text

string - Text delimiter. String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

skip

number - Number of header lines to skip at top of input file. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
