* `examples/minimal_lsp.rs` – compact LSP server showing definition, completion, hover, rustfmt-based formatting, and dummy diagnostics. Advertises UTF-8 offset encoding. * `examples/manual_test.sh` – FIFO script that streams the canonical nine LSP packets so anyone can validate the server from two terminals. No new runtime deps; `anyhow` stays under [dev-dependencies].

# Simple nine-packet LSP test for examples/minimal_lsp.rs
|
||
# Usage (two tabs):
|
||
#
|
||
# mkfifo /tmp/lsp_pipe # one-time setup
|
||
# # tab 1 – run the server
|
||
# cat /tmp/lsp_pipe | cargo run --example minimal_lsp
|
||
#
|
||
# # tab 2 – fire the packets (this script)
|
||
# bash examples/manual_test.sh # blocks until server exits
|
||
#
|
||
# If you don’t use a second tab, run the script in the background:
|
||
#
|
||
# bash examples/manual_test.sh & # writer in background
|
||
# cat /tmp/lsp_pipe | cargo run --example minimal_lsp
|
||
#
|
||
# The script opens /tmp/lsp_pipe for writing (exec 3>) and sends each JSON
|
||
# packet with a correct Content-Length header.
|
||
#
|
||
# One-liner alternative (single terminal, no FIFO):
|
||
#
|
||
# cargo run --example minimal_lsp <<'EOF'
|
||
# … nine packets …
|
||
# EOF
|
||
#
|
||
# Both approaches feed identical bytes to minimal_lsp via stdin.
