Browse Structure and Interpretation of Computer Programs (SICP) from the command line.

sicp is a single pure-Go binary. It reads public data from sarabander.github.io/sicp over plain HTTPS, shapes it into clean records, and prints output that pipes into the rest of your tools. No API key, nothing to run alongside it.

The same package is also a resource-URI driver, so a host program like ant can address sicp as sicp:// URIs.

go install github.com/tamnd/sicp-cli/cmd/sicp@latest

Or grab a prebuilt binary from the releases, or run the container image:

docker run --rm ghcr.io/tamnd/sicp:latest --help

sicp chapters                         # list all 5 SICP chapters
sicp chapters -o json                 # as JSON, ready for jq
sicp chapters -o csv                  # as CSV for spreadsheets
sicp chapters -n 3                    # first three chapters only
sicp --help                           # the whole command tree

Every command shares one output contract: -o table|json|jsonl|csv|tsv|url|raw, --fields to pick columns, --template for a custom line, and -n to limit. The default adapts to where output goes (a table on a terminal, JSONL in a pipe), so the same command reads well by hand and parses cleanly downstream.

The same operations are available over HTTP and as an MCP tool set for agents, with no extra code:

sicp serve --addr :7777    # GET /v1/page/<path>  returns NDJSON
sicp mcp                   # speak MCP over stdio

sicp registers a sicp domain the way a program registers a database driver with database/sql. A host enables it with one blank import:

import _ "github.com/tamnd/sicp-cli/sicp"

Then ant (or any program that links the package) dereferences sicp:// URIs without knowing anything about sicp:

ant get sicp://page/<path>   # fetch the record
ant cat sicp://page/<path>   # just the body text
ant ls  sicp://page/<path>   # the pages it links to, each addressable
ant url sicp://page/<path>   # the live https URL

cmd/sicp/   thin main: hands cli.NewApp to kit.Run
cli/                 assembles the kit App from the sicp domain
sicp/                the library: HTTP client, data models, and domain.go (the driver)

Push a version tag and GitHub Actions runs GoReleaser, which builds the archives, Linux packages, the multi-arch GHCR image, checksums, SBOMs, and a cosign signature:

git tag v0.1.0
git push --tags

The Homebrew and Scoop steps self-disable until their tokens exist, so the first release works with no extra secrets.
