clawbot ac721390de Exponentiation and modulo in the calculator (closes #3)
check / check (push) Successful in 1m7s
Details 
The calculator now takes `^` (or `**`) for powers and `%` for modulo. Powers bind tighter than a sign on their left and group to the right, so `-2^2` is `-4` and `2^3^2` is `512`; `%` sits with `*` and `/` and takes the sign of the divisor. A small parser of our own replaces `go/parser`, which cannot express `^`; `go/constant` still computes.

A whole-number exponent is exact; a fractional one is computed in float64. Every number is held as a fraction under 4096 bits, and a float64 result must be a normal double, so one message cannot stall the bot; anything else gets "That needs a number too large or too small for me."

Disclosure: tiny values below about 2.2e-308, which `next` answered, are now refused.

clawbot 09a5caa8ab Move the command tree into internal/cli (closes #8)
check / check (push) Successful in 1m40s
Details 
`cmd/simplexcalc/` now holds only `main.go`, whose body is one call, `os.Exit(cli.Main(version))`, as the Go style guide requires. The command tree and the `run` and `version` commands moved unchanged into `internal/cli`, with tests for `version` and for an unknown command. Output streams, exit statuses and the `-X main.version` build flag are as before.

Disclosure: the comment in `execute` saying cobra has already printed the error is false, since the root command silences cobra's errors; it moved unchanged and is left for a follow-up.

clawbot 16649e0f2f A SimpleX Chat bot that answers arithmetic (closes #1)
check / check (push) Successful in 54s
Details 
Remove the template's HTTP service, database and fx wiring. Add exact
arithmetic on go/parser and go/constant, a client that runs simplex-chat
as a child process and drives its WebSocket API, and the bot, which keeps
an auto-accepting address and replies to each message. The image adds the
checksum-pinned simplex-chat v7.0.2 on Ubuntu 22.04.
