get_input_file: Load an ASCII input file

In tabrasel/WetlandTools: General utility functions for TerrainWorks

Load an ASCII input file

Description

TerrainWorks scripts read instructions and parameter values from an ASCII file. These files are formatted using a "keyword: argument" format. The keywords and associated arguments can come in any order and each keyword may have any number of arguments, including no argument. Arguments use a "parameter = value" format, with each argument separated by a comma. For example, here is the keyword: argument input line for specifying reach length in a synthetic channel network: REACH LENGTH: FIXED=100., BREAK AT JUNCTIONS. Here, "REACH LENGTH" is the keyword, there are two arguments, one of which requires a value.

Usage

get_input_file(infile = "nofile")

Arguments

infile

File name with full path. If no file is specified, a window opens to choose a file interactively.

Value

A tibble with each row corresponding to one line in the input file.
