These instructions work for OSX Catalina only and are a bit different than the Linux version shown at urlwatch<\/a>.<\/p>\n

\r\npython3 -m pip install pyyaml minidb requests keyring appdirs lxml cssselect html2text\r\npython3 -m pip install urlwatch\r\nEDITOR=nano\r\nurlwatch --edit\r\n# CTRL+X leave the editor without saving\r\n<\/pre>\n
Then edit ~\/Library\/Application Support\/urlwatch\/urls.yaml<\/p>\n
\r\nkind: url\r\nmax_tries: 3\r\nname: Camptoi\r\nurl: https:\/\/www.camptoi.de\r\nfilter:\r\n- element-by-id: product-desc-18713727425\r\n- html2text:\r\n    body_width: 0\r\n    ignore_images: false\r\n    ignore_links: false\r\n    inline_links: false\r\n    method: pyhtml2text\r\n    pad_tables: false\r\n    single_line_break: true\r\n    unicode_snob: true\r\n<\/pre>\n
After that we create the Telegram bot<\/a> by sending<\/p>\n
\r\n\/newbot\r\n<\/pre>\n
to user BotFather and record the <API> from the response.<\/p>\n
We also need to send a dummy message to the new bot so we can look up the sender <ID><\/p>\n
\r\nhttps:\/\/api.telegram.org\/bot<API>\/getUpdates\r\n<\/pre>\n
<API> and <ID> are both entered into ~\/Library\/Application Support\/urlwatch\/urlwatch.yaml<\/p>\n
\r\n...\r\n  telegram:\r\n    bot_token: '<API>'\r\n    chat_id: '<ID>'\r\n    enabled: true\r\n---\r\n<\/pre>\n
As we have no cron under MacOS we need a parameter file to run launchd<\/a>. Should be placed at ~\/Library\/LaunchAgents\/com.urlwatch.plist<\/p>\n
\r\n<?xml version="1.0" encoding="UTF-8"?>\r\n<!DOCTYPE plist PUBLIC "-\/\/Apple\/\/DTD PLIST 1.0\/\/EN" "http:\/\/www.apple.com\/DTDs\/PropertyList-1.0.dtd">\r\n<plist version="1.0">\r\n\t<dict>\r\n\t\t<key>Label<\/key>\r\n\t\t<string>com.urlwatch<\/string>\r\n\t\t<key>Program<\/key>\r\n\t\t<string>\/Users\/wjst\/opt\/anaconda3\/bin\/urlwatch<\/string>\r\n\t\t<key>RunAtLoad<\/key>\r\n        <true\/>\r\n        <key>StartInterval<\/key>\r\n        <integer>9000<\/integer>\r\n        <key>KeepAlive<\/key>\r\n         <true\/>       \r\n\t<\/dict>\r\n<\/plist>\r\n<\/pre>\n
Ultimately, the agent is started (or stopped) using<\/p>\n
\r\nlaunchctl load -w  ~\/Library\/LaunchAgents\/com.urlwatch.plist               \r\nlaunchctl unload ~\/Library\/LaunchAgents\/com.urlwatch.plist\r\n<\/pre>\n\n
