# README for coupons This project exists to make it easy to query the current sale papers for select grocery stores, including specifically Publix. Frontends include cli and a webapp (python flask). ## Upstream This project's upstream is at . ## Features * simple cli * simple wsgi web app with minimal javascript * caching of results for faster lookups during the same day ## Alternatives Visiting manually, or each store's website. I previously started using selenium (see [aux/ads1.py](aux/ads1.py) in initial commit) but that was not necessary. ## Reason for existence To simplify and automate searching for items currently on sale. ## Using ### Command line interface Basic usage is pretty simple. You need to specify a store at a minimum. When the script visits the webpage, it will cache the file to `$XDG_CACHE_DIR/coupons/` to reduce the amount of work needed during the same day. ./coupons.py --store "publix" --search "candy" To use standard input from a fully-cached javascript response from the website, you could run this. <~/.cache/coupons/publix_2022-09-01.json ./coupons.py --stdin --clean --search "candy" --pretty An already-cleaned json file would not need the **--clean** flag. But the cached values are the exact javascript+json payload from the server. See also `./coupons.py --help`. ### Web app Run a simple dev environment. FLASK_APP=coupons_web.py FLASK_DEBUG=True flask run --host='0.0.0.0' For a more robust production environment, drop the `extra/wsgi-coupons.conf` apache config into your apache httpd conf directory and configure it as documented in there. ### Visiting the web app with curl $ curl http://d2-03a/coupons/search/dog --header 'Accept: application/json' ; printf '\n' [{"publix": {"Publix Weekly Ad: 9/7-9/13 or 9/8-9/14": {"Buy One Get Ones": ["Healthy Hide Good'n Fun Dog Treats Triple Flavor Ribs or Wings, 12 oz, at $11.99 ($5.99)"]}, "Unadvertised Deals: 9/7-9/13": {"Pet Care": ["Blue Dry Dog Food, 5 lb, $14.99"]}, "Extra Savings Flyer: 8/27-9/9": {"Meat": ["Greenfield Natural Meat Co. Bratwurst 12 oz, Hot Dogs 13 oz or Lunchmeat, 7 oz, $4"]}}}, {"ingles": {"Ingles Ad & Coupons: 9/7-9/13": {"Meat": ["Gwaltney Hot Dogs, 12 oz, $1.48"]}}}, {"food lion": {"Food Lion Ad & Coupons: 9/7-9/13": {"Pet Care": ["Rachael Ray Nutrish Dry Dog Food, 5.5-6 lb, $10.99"]}}}] $ curl -X POST http://d2-03a/coupons/search/ --data 'mayo' --header 'Accept: application/json' ; printf '\n' [{"publix": {"Publix Weekly Ad: 9/7-9/13 or 9/8-9/14": {"Buy One Get Ones": ["Duke's Mayonnaise, 30-32 oz, at $5.23 ($3.11)", "Hellmann's Mayonnaise, 15-20 oz, at $5.75 ($2.87)"]}, "Extra Savings Flyer: 9/10-9/23": {"Grocery": ["Hellmann's Mayonnaise, 24-30 oz, $3.99", "Hellmann's Mayonnaise, Spicy Mayonnaise or Vegan Dressing & Spread, 11.5 oz, $3", "Primal Kitchen Mayonnaise, 12 oz, $8.99", "Sir Kensington's Special Sauce or Chipotle Mayonnaise, 12 oz, $4"]}}}] The API accepts a few URL parameters, including `&date=YYYY-MM-DD` to use that day's cached results (it does not time travel for you) and `?nocache=1`. ## Improvements * Add flask-correct logger mechanisms? ## Dependencies For the web app: * apache with `mod_wsgi` * python3-flask For AlmaLinux 8: * python3-flask * python3-mod_wsgi * httpd ## Building or changing Only a few stores are currently supported. The southernsavers.com website lists other stores that are probably drop-in capable. To learn the widgets.json path needed, use Developer Tools in a web browser to capture the full widgets.json path and add it to the **stores_url** dict. ## References * Developer Tools in Firefox * [stackbin](https://bgstack15.ddns.net/cgit/stackbin/)
