This repository contains seven tools:

• diff_dbf compares dBase database files (.dbf file extension).
• diff_gv compares files in Graphviz dot language.
• diff_shp compares shapefiles.
• max_diff_rect compares CSV files.
• nccmp compares NetCDF files.
• selective_diff compares directories.
• test_compare launches user-defined processes and compares results with previous runs.

Each of these tools can be run directly on the command line. Some of them call others from this repository.

selective_diff

selective_diff compares two directories, recursively. The value of selective_diff is that it has better than diff capabilities for some chosen types of files: NetCDF, numeric CSV, shapefile.

Note that arguments should be two directories, not two files.

Dependencies: see requirements, plus ndiff.

test_compare

Test code and compare results.
