# cligj — Click params for commmand line interfaces to GeoJSON

License: permissive · Maintenance: dormant · Downloads: 9.6M/mo

## What it is and what it does

cligj is a library that packages common command-line argument and option patterns for GeoJSON processing into reusable Click decorators. It abstracts away boilerplate for handling GeoJSON input/output modes, coordinate precision, projection types, and feature collection vs. sequence formats—patterns that appear repeatedly in geospatial CLI tools. The library depends only on click and is designed to let developers quickly build consistent, interoperable command-line interfaces for geospatial data without reimplementing standard argument handling.

The package provides decorators like `features_in_arg`, `sequence_opt`, `use_rs_opt`, and others that handle GeoJSON-specific concerns: reading features from files or stdin, choosing between feature collections and line-delimited sequences, applying coordinate precision, and selecting geographic or projected coordinate systems. It is primarily useful for developers building geospatial data processing pipelines or command-line tools that need to accept and emit GeoJSON in standard ways.

Use it for:

- Build a geospatial data conversion CLI that accepts GeoJSON input and outputs in multiple formats with consistent argument handling.
- Create a feature filtering or transformation command-line tool that reads GeoJSON features and writes them as a collection or sequence.
- Develop a batch geospatial processing tool that needs to handle both file and stdin input with standard verbosity and formatting options.
- Standardize CLI interfaces across multiple geospatial utilities so they share common argument patterns and help text.
- Implement a GeoJSON validation or analysis command that supports both pretty-printed and compact JSON output modes.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides reusable Click command-line argument and option decorators for building consistent GeoJSON processing tools.

Yes, if you are building GeoJSON command-line tools and want to avoid reimplementing standard argument patterns. The low install friction and permissive license make it a safe dependency. However, be aware that maintenance is dormant—the last release was in 2021 and there have been no commits since February 2024. If you need active maintenance or expect to rely on updates for compatibility with future click versions, consider whether the project's stability meets your risk tolerance.

## Install

pip install cligj
uv add cligj
poetry add cligj

## Installing cligj

Before you install: Low install friction with a single runtime dependency on click. Maintenance is dormant—last release was in 2021 and no commits since February 2024—but the package remains archived-free and has seen no security vulnerabilities.

License in practice: BSD license is permissive, allowing commercial and private use with minimal restrictions.

Quickstart:

pip install cligj

import click
import cligj

@click.command()
@cligj.features_in_arg
@cligj.sequence_opt
def my_command(features, sequence):
    for feature in features:
        click.echo(feature)

Verify before relying:

- Whether the package works reliably with modern Python versions despite dormant maintenance status.
- Compatibility with recent versions of click and whether breaking changes in click affect cligj decorators.
