SimpleX Calculator
A calculator bot built with the SimpleX Chat Node.js library.
Each user who connects via the bot's business address receives a calculator message with keys as commands. The bot replaces this message after each input.

+,=,addorc. Expressions like(2 + 3) × 4are entered as one number, and the bot replies to them with the result. - The bot deletes keys and numbers, tapped or sent, and logs each computed operation, such as
15 + 10 = 25. - After 10 minutes without input, the bot turns the calculator off and discards the calculation; tap any key to turn it on.

Run
npm install
npm run build
npm start
The bot prints its address and keeps its data in ./data.
To add a SimpleX name to the address, register the name with the address short link, and run npm start -- --domain yourname.simplex. The name is kept when the bot starts without --domain.
To use the library from this repository, build it and run npm install --no-save ../../packages/simplex-chat-nodejs instead of npm install.
Test
npm test
A local SMP server is started for the end-to-end test. On Linux, smp-server is downloaded from simplexmq releases; to use another build, or on other systems, set SMP_SERVER to the path of smp-server.
