Data generator for the-law-factory project (http://www.LaFabriqueDeLaLoi.fr)

Code used to generate the API available at: http://www.LaFabriqueDeLaLoi.fr/api/

Install the dependencies

You should set up a dedicated virtualenv with Python 3.5+:

virtualenv -p $(which python3) venv
source venv/bin/activate

Using Pypy can seriously boost performance. You can easily install it and create a virtualenv with it for instance by installing Pyenv:

pyenv install pypy3.5-6.0.0
pyenv virtualenv pypy3.5-6.0.0 lafabrique
pyenv activate lafabrique

Then with your choice of virtualenv activated, install the dependencies:

sudo apt install libxml2-dev libxslt-dev # necessary for lxml
pip install --upgrade setuptools pip # not necessary but always a good idea
pip install -e .
pip install -Ur requirements.txt # to get the latest version of those dependencies

Generate data for one bill

• search for the bill's procedure page on Senat.fr or Assemblee-nationale.fr.

• execute tlfp-parse script using the procedure page:

tlfp-parse <url>

The data is generated in the "data" directory. You can change this default behavior by inputting a data path as extra argument: tlfp-parse <url> <dataDir>.

For example, to generate data about the "Enseignement supérieur et recherche" bill:

tlfp-parse http://www.senat.fr/dossier-legislatif/pjl12-614.html
ls data/pjl12-614/

You can also use directly Senate's ids such as: tlfp-parse pjl12-614

Development options --debug, --enable-cache and --only-promulgated can also be used.

Generate data for many bills

To generate all bills from 2008, you can pipe a list of ids or urls into tlfp-parse-many.

A convenient way to do so is to use senapy:

senapy-cli doslegs_urls --min-year=2008 | tlfp-parse-many data/

See senapy-cli doslegs_urls help for more options. You can also use anpy with anpy-cli doslegs_urls.

Serve bills locally for The Law Factory website

First, you need to build data for all desired bills.

Then generate the files required by the frontend:

python tlfp/generate_dossiers_csv.py data/       # generates home.json and dossiers_promulgues.csv used by the searchbar
python tlfp/tools/assemble_procedures.py data/   # generates dossiers_n.json files used by the Navettes viz

Finally, serve the data directory however you like. For instance, you can serve it on a specific port with a simple http server like nodeJs', in which case, you'll need to enable cors: just install http-server with npm and run it in data directory on a given port (8002 in the example):

npm install -g http-server
cd data & http-server -p 8002 --cors

Generate git version for a bill

Work In Progress

You can export all your bills as git repositories: python tlfp/tools/make_git_repos.py git_export

Other things you can do

• parse a sénat dosleg: senapy-cli parse pjl15-610
• parse an AN dosleg: anpy-cli parse http://www.assemblee-nationale.fr/13/dossiers/deuxieme_collectif_2009.asp
• parse all the sénat doslegs: senapy-cli doslegs_urls | senapy-cli parse_many senat_doslegs/
• parse all the AN doslegs anpy-cli doslegs_urls | anpy-cli parse_many an_doslegs/
• generate a graph of the steps: python tlfp/tools/steps_as_dot.py data/ | dot -Tsvg > steps.svg

Tests

To run the tests, you can follow the .travis.yml file.

git clone https://github.com/regardscitoyens/the-law-factory-parser-test-cases.git
python tests/test_regressions.py the-law-factory-parser-test-cases

If you modify something, best is to regenerate the test-cases with the --regen flag:

python tests/test_regressions.py the-law-factory-parser-test-cases --regen

To make the tests faster, you can also use the --enable-cache flag. To clear the cache, you can remove the directory returned by lawfactory_where_is_my_cache. To update the meta-infos (ex: a new political group was added), you need to clear the test-cases directory of all the root .json files.

You can also watch for parts of the code not yet covered by the tests:

• First, install coverage: pip install coverage
• Then, you can execute bash coverage.sh
• Then, the report is in htmlcov/index.html
