              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,

           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,

              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.

## Introduction

cq-cli is a Command Line Interface for executing CadQuery scripts and converting their output to another format. It uses a plugin system where "codecs" can be placed in the `cqcodecs` directory and will be automatically loaded and used if a user selects that codec from the command line.

Input and output files can be specified via arguments, but cq-cli also supports stdin, stdout, and stderr streams so that it can be used in a pipeline.

**Requires Python 3.11 or later.** Linux, macOS, and Windows are supported, though some features may behave differently on Windows.

## Installation

### uv (preferred) ⭐️

[uv](https://docs.astral.sh/uv/) is the recommended way to install and run cq-cli. It handles Python version management and virtual environments automatically.

```
uv venv --python 3.11
source .venv/bin/activate  # Windows: .venv\Scripts\activate
uv sync
```

Once complete, run cq-cli with:
```
cq-cli --help
```

### pip

It is strongly recommended to use a Python virtual environment when installing via pip.

cq-cli is not available on PyPI, so it must be installed from source using pip and git. git must be installed for this to work.

```
pip install git+https://github.com/CadQuery/cq-cli.git
```

Once the installation is complete, the CLI can be invoked as:
```
cq-cli --help
```
or:
```
python -m cq_cli.main --help
```

## Usage

```
cq-cli [-h] [--codec CODEC] [--infile INFILE] [--outfile OUTFILE]
       [--errfile ERRFILE] [--params PARAMS] [--outputopts OPTS]
       [--getparams GETPARAMS] [--validate VALIDATE] [--expression EXPRESSION]
```

Command line utility for converting CadQuery script output to various output formats.

| Argument | Description |
|---|---|
| `-h`, `--help` | Show help message and exit |
| `--codec CODEC` | The codec to use for conversion (e.g. `step`, `stl`, `svg`, `dxf`, `glb`, `gltf`, `threejs`). Can be omitted if `--outfile` has a recognised extension. Multiple codecs can be specified separated by `;` — must match the number of `--outfile` entries. |
| `--infile INFILE` | The input CadQuery script (`.py`) or FreeCAD file (`.fcstd`). Reads from stdin if omitted. |
| `--outfile OUTFILE` | File to write the converted output to. Prints to stdout if omitted. Multiple output files can be specified separated by `;`. |
| `--errfile ERRFILE` | File to write errors to. Prints to stderr if omitted. |
| `--params PARAMS` | Parameters to pass to the script. Accepts: a JSON file path, a JSON string (`{"width":10}`), or a colon/semicolon delimited string (`width:10;height:5;`). |
| `--outputopts OPTS` | Codec-specific options as a colon/semicolon delimited string. e.g. `width:100;height:200;` |
| `--getparams GETPARAMS` | Analyse the script and write parameter metadata as JSON. Pass a file path to write to a file, or `true` to print to stdout. |
| `--validate VALIDATE` | Set to `true` to validate the script without producing output. |
| `--expression EXPRESSION` | A Python expression to evaluate and render (e.g. `my_shape(x=5)`). Useful for rendering a specific part from a file that contains multiple functions. |

## Examples

1. Find out what codecs are available.
```
cq-cli --codec help
```
2. Validate a CadQuery script.
```
cq-cli --validate true --infile /input/path/script.py
```
3. Convert a CadQuery script to STEP format and output to stdout.
```
cq-cli --codec step --infile /input/path/script.py
```
4. Convert a CadQuery script to STEP format and write to a file.
```
cq-cli --codec step --infile /input/path/script.py --outfile /output/path/newfile.step
```
5. Convert a CadQuery script and write any errors to a separate file.
```
cq-cli --codec step --infile /input/path/script.py --errfile /error/path/error.txt
```
6. Convert a CadQuery script using stdin and stdout streams. This example counts the lines in the resulting STEP output.
```
cat /input/path/script.py | cq-cli --codec step | wc -l
```
7. Let cq-cli infer the codec from the output file extension.
```
cq-cli --infile /input/path/script.py --outfile /output/path/newfile.stl
```
8. Convert to multiple output formats in a single invocation.
```
cq-cli --infile /input/path/script.py --outfile /output/path/model.step;/output/path/model.stl
```
9. Convert a CadQuery script to SVG, passing output options to influence the resulting image.
```
cq-cli --codec svg --infile /input/path/script.py --outfile /output/path/newfile.svg --outputopts "width:100;height:100;marginLeft:12;marginTop:12;showAxes:False;projectionDir:(0.5,0.5,0.5);strokeWidth:0.25;strokeColor:(255,0,0);hiddenColor:(0,0,255);showHidden:True;"
```
10. Convert a CadQuery script to STL, adjusting mesh quality. Explanation of linear vs angular deflection can be found [here](https://dev.opencascade.org/doc/occt-7.1.0/overview/html/occt_user_guides__modeling_algos.html#occt_modalg_11_2).
```
cq-cli --codec stl --infile /input/path/script.py --outfile /output/path/script.stl --outputopts "linearDeflection:0.3;angularDeflection:0.3"
```
11. Extract parameter information from a script. Omit the file path to print JSON to stdout.
```
cq-cli --getparams /output/path/params.json --infile /input/path/script.py
```
12. Pass JSON parameter information from a file to the script.
```
cq-cli --codec stl --infile /input/path/script.py --outfile /output/path/output.stl --params /parameter/path/parameters.json
```
13. Pass JSON parameter data as a string on the command line.
```
cq-cli --codec stl --infile /input/path/script.py --params "{\"width\":10}"
```
14. Pass parameters as a colon/semicolon delimited string.
```
cq-cli --codec stl --infile /input/path/script.py --outfile test.stl --params "width:2;centered:True"
```
15. Render a specific function from a file using `--expression`.
```
cq-cli --codec step --infile /input/path/script.py --outfile /output/path/part.step --expression "my_part(x=5)"
```

### Development Setup

The recommended way to set up a development environment is with [uv](https://docs.astral.sh/uv/).

```
git clone https://github.com/CadQuery/cq-cli.git
cd cq-cli
uv venv --python 3.11
source .venv/bin/activate  # Windows: .venv\Scripts\activate
uv sync --extra dev
```

Alternatively, using pip:
```
git clone https://github.com/CadQuery/cq-cli.git
cd cq-cli
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -e .[dev]
```

Run the test suite:
```
pytest -v --ignore=tests/test_freecad.py
```

### Adding a Codec

The codec plugin system is based on naming conventions so that cq-cli knows what codec options to accept from the user. When adding a codec, place it in the `cqcodecs` directory and follow the naming convention `cq_codec_[your codec name].py`. The `your codec name` part of the filename will automatically be used as the codec name specified by the user.

A good starting point is [cqcodecs/cq_codec_step.py](src/cq_cli/cqcodecs/cq_codec_step.py), which shows a simple codec implementation that relies on CadQuery to do the heavy lifting. At minimum, your codec needs a `convert` function that accepts a [CQGI BuildResult object](https://cadquery.readthedocs.io/en/latest/cqgi.html#cadquery.cqgi.BuildResult) and returns a string or bytes representing the converted model. If the codec writes the output file directly, return `None` and cq-cli will assume the output was written to disk.

### Adding a Codec Test

A test is required when adding a codec to cq-cli. Add a file named `test_[your codec name]_codec.py` in the `tests` directory. [tests/test_step_codec.py](tests/test_step_codec.py) is a good template.

### Exit Codes

| Code | Meaning |
|---|---|
| **0** | Operation completed successfully. |
| **1** | The CadQuery script could not be read from `--infile`. |
| **2** | Usage error — incorrect or insufficient arguments. |
| **3** | No valid codec was provided or could be inferred. |
| **100** | Error while running the CadQuery script (build error, possibly from OCCT). |
| **200** | Error while running the conversion codec. |
