Habulara - Toolkit for Processing Tabular Data

Note: This package is under heavy development and of prototype quality at the moment. Expect significant performance regressions across releases and breaking changes without notification until we reach the first major version.

Habulara is a Haskell library and command line application that provides high-level means to process tabular data, in particular CSV files in a declarative fashion.

Installation

If you are on Nix:

git clone git@github.com:telostat/habulara.git
cd habulara
nix-env -i -f default.nix

Alternatively, you can check statically built binaries under releases.

Usage

As a standalone application

To process a CSV file as per a given HAB (Habulara mapping specification) file:

$ habulara process --help
Usage: habulara process --spec SPEC [--input INPUT] [--output OUTPUT]
  Process given CSV data with given specification

Available options:
  --spec SPEC              Habulara mapper specification filepath
  --input INPUT            Input CSV data filepath (`-` for stdin, default)
  --output OUTPUT          Output CSV data filepath (`-` for stdout, default)
  -h,--help                Show this help text

... example:

habulara process --spec var/examples/weather-stations/spec.yaml --input var/examples/weather-stations/data.csv

As a library

TODO: Add a quick example for demonstrating library usage.

Development

Releasing

Below is the release process. Run these under the nix-shell, but nix-shell --pure won't work for now due to missing nix-build command (We will attend it later).

Note that <NEW-VERSION> is given without v prefix (For example: 1.0.0).

git checkout main
git pull
./release.sh -n <NEW-VERSION>
