Summary Dependency Versions

@elaraai/e3-cli

Command-line interface for e3 (East Execution Engine).

Installation

npm install -g @elaraai/e3-cli

Every command that takes <repo> accepts either a local path or an http(s):// URL. The transport is detected from the argument shape. Set E3_REPO to default the repo argument when omitted (where the positional is optional).

Repository

e3 repo create <repo>                # Create a new repository
e3 repo status <repo>                # Show repository status
e3 repo remove <repo> [-r]           # Remove a repository (-r removes workspaces first)
e3 repo gc <repo> [--dry-run]        # Remove unreferenced objects
e3 repo list <server-url>            # List repositories on a server

Packages

e3 package import <repo> <zip>            # Import package from .zip
e3 package export <repo> <pkg> <zip>      # Export package to .zip
e3 package list <repo>                    # List installed packages
e3 package remove <repo> <pkg>            # Remove a package

Workspaces

e3 workspace create <repo> <name>                            # Create empty workspace
e3 workspace deploy <repo> <ws> <pkg>[@<ver>]                # Deploy a package
e3 workspace deploy <repo> <ws> --from-zip <path.zip>        # Import + create + deploy in one shot
e3 workspace export <repo> <ws> <zip>                        # Export workspace as a package
e3 workspace list <repo>                                     # List workspaces
e3 workspace status <repo> <ws>                              # Detailed workspace status
e3 workspace remove <repo> <ws>                              # Remove a workspace

Datasets

Dataset paths use the flat form <ws>.<name>. The CLI resolves <name> against inputs and task outputs automatically.

e3 dataset get <repo> <ws.name> [-f east|json|beast2]
e3 dataset set <repo> <ws.name> <file> [--type <spec>] [--type-file <path>]
e3 dataset list <repo> <ws> [-l]                # List dataset paths (with -l for table view)
e3 dataset status <repo> <ws.name>              # Show one dataset's kind/type/status/size
e3 dataset find <repo> <ws> <pattern>           # Substring or glob (`*`, `?`) match across names

Tasks

e3 task list <repo> <ws>                        # List tasks with execution status
e3 task logs <repo> <ws.task> [--follow]        # Stream task logs

Dataflow execution

e3 dataflow run <repo> <ws> [--filter <p>] [--concurrency <n>] [--force]

After a successful run, the CLI prints the task output paths so you can read them straight away:

Summary: 2 executed, 0 cached, ...
Outputs:
  dev.greet  String  14 B
  dev.shout  String  16 B

Ad-hoc task execution

e3 run <repo> <pkg.task> <inputs...> -o <out>
e3 run <repo> <pkg@1.0.0.task> <in.beast2> -o <out.beast2>

Watch / live development

e3 watch <source.ts> <repo> <ws> [--start] [--abort-on-change]

Authentication

e3 auth login <server>      # OAuth2 device-flow login
e3 auth logout <server>     # Clear saved credentials
e3 auth status              # List saved credentials
e3 auth token <server>      # Print access token (curl integration)
e3 auth whoami [server]     # Show current identity

curl -H "Authorization: Bearer $(e3 auth token https://example.com)" \
  https://example.com/api/repos/my-repo/status

Utilities

e3 convert [input] [--from <fmt>] [--to <fmt>] [-o <out>] [--type <spec>]
e3 completion install        # Detect your shell and wire up tab completion
e3 completion uninstall      # Undo the above
e3 completion {bash|zsh|fish}  # Print the raw script (manual install)

e3 completion install is the one-shot setup — it detects $SHELL, appends eval "$(e3 completion bash)" (or the zsh/fish equivalent) to your rc file, and is idempotent on re-run. Override detection with --shell <bash|zsh|fish>.

If you'd rather wire it up yourself, e3 completion bash > /etc/bash_completion.d/e3 (and equivalents) work too.

The completion script delegates dynamic lookups (workspace names, dataset paths, package names) to a hidden e3 __complete handler.

Defaulting the repository

When the positional <repo> is optional (every command that takes one as the first argument, except run and watch), the value is resolved in this order:

Explicit positional argument.
E3_REPO environment variable.
. (current directory).

So once you're inside a repo, export E3_REPO=. lets you drop the leading .:

export E3_REPO=.
e3 dataset get dev.greet
e3 dataflow run dev

Example

# Create a repository, deploy a package, run the dataflow
e3 repo create ./my-project
e3 workspace deploy ./my-project dev --from-zip ./hello.zip
e3 dataset set ./my-project dev.name ./name.east
e3 dataflow run ./my-project dev

# Read the results
e3 dataset get ./my-project dev.greet

Claude Code plugin

The East ecosystem also ships a Claude Code plugin — East language skills, example search, and preemptive diagnostics for East code — installed separately from the elaraai marketplace:

# Inside Claude Code
/plugin marketplace add elaraai/east-workspace
/plugin install east@elaraai

# From a terminal
claude plugin marketplace add elaraai/east-workspace
claude plugin install east@elaraai
