=====
`https://opcut.herokuapp.com/`
`opcut` is cutting stock problem optimizer
(`https://en.wikipedia.org/wiki/Cutting_stock_problem`) utilizing multiple
panels and guillotine cuts (end-to-end cuts). This project includes:
* multiple back-end optimizer implementations
* command line front-end
* REST service API (OpenAPI definition)
* single-page web application front-end
Runtime requirements
--------------------
* python >=3.8
.. note::
on Ubuntu, if pycairo is not available, additional
``apt install gcc pkg-config libcairo2-dev python3-dev`` is required
Install
-------
::
$ pip install opcut
.. note::
Windows distribution, with embedded python, is available at
`https://github.com/bozokopic/opcut/releases`
Usage
-----
`opcut` command is interface for execution of three distinct actions:
* `opcut calculate ...`
Calculation of cutting stock problem. Input parameters and result is
formated as JSON data (JSON, YAML or TOML).
* `opcut generate ...`
Generate output representation (SVG, PDF, ...) based on calculation
result.
* `opcut server ...`
Run HTTP server providing single-page web application interface and
OpenAPI interface.
(default listening address is http://0.0.0.0:8080).
For additional command line arguments, run ``opcut --help`` or
``opcut <action> --help``.
`opcut calculate`
'''''''''''''''''
Example::
$ opcut calculate --input-format yaml --output result.json << EOF
cut_width: 1
panels:
panel1:
width: 100
height: 100
items:
item1:
width: 10
height: 10
can_rotate: false
EOF
`opcut generate`
''''''''''''''''
Example::
$ opcut generate --output output.pdf result.json
`opcut server`
''''''''''''''
Example::
$ opcut server
Development requirements
------------------------
* C99 compiler (gcc, clang, ...)
* nodejs >=7
* yarn
Build
-----
Build tool used for `opcut` is pydoit (`http://pydoit.org/`). It can be
installed together with other python dependencies by running::
$ pip install -r requirements.pip.dev.txt
For listing available doit tasks, use::
$ doit list
Default task::
$ doit
creates wheel package inside `build` directory.
