README

interpolate

interpolate takes a csv file representing a 2d matrix of number strings, and outputs the same matrix, but with any "nan" values interpolated as the average of non-diagonal neighbours.

Installation

Requires go v1.14 or later. Follow https://golang.org/doc/install, then:

git clone https://github.com/sb10/interpolate.git
cd interpolate
make install

Usage

interpolate your.csv > interpolated.csv

See the example input and output csv files in the data subdirectory.

Developers

To develop this code base, you should use TDD. To aid this, the test suite is written using GoConvey.

To install goconvey:

cd ~/somewhere_else
git checkout https://github.com/smartystreets/goconvey.git
go build
mv goconvey $GOPATH/bin/

To use goconvey:

cd ~/your_clone_of_this_repository
goconvey &

This will pop up a browser window which will aid in the red-green-refactor cycle.

To run the tests on the command line: go test ./... or make test

To run the benchmarks: go test -run Bench -bench=. ./... or make bench

Before committing any code, you should make sure you haven't introduced any linting errors. First install the linters: curl -sfL https://install.goreleaser.com/github.com/golangci/golangci-lint.sh | sh -s -- -b $(go env GOPATH)/bin v1.31.0

Then: make lint
