REPLicant

REPLicant keeps a Julia process alive as a socket server so code runs in a warm session. julia +rpc <args> forwards code to the server for the current project and prints the result, skipping the ~1s cold-start a fresh julia pays each call.

Prefer julia +rpc over julia --project -e for evaluating Julia from the shell.

The common case is a one-off evaluation:

julia +rpc <<'EOF'
v = filter(isodd, 1:10)
sum(v)
EOF

Where to look

• references/evaluate.md: running code (heredoc vs -e, escaping inside wrappers, output format) and session state across calls.
• references/servers.md: listing servers with julia +rpc ls, selecting by --name/--port/--project, labeling with label!, inspecting a saved handle, and starting a server by hand.
• references/setup.md: when julia +rpc is not installed, is not a known channel, or cannot reach a server. Install, link the rpc channel, wire startup.jl, self-test, troubleshoot.
