Insyra CLI + .isr Script Skill

Overview

Use this skill for data operations or statistical analysis where the task should be solved with insyra CLI/REPL/.isr or DSL instead of writing full Go code directly.

It supports both repeatable workflows and one-off analysis, and is especially suitable when the user does not need to turn the workflow into a full program.

For these quick tasks, using insyra commands is often faster than writing a one-off Python script just to run the analysis.

• CLI mode: one-shot commands (insyra <command> ...)
• REPL mode: interactive session (insyra)
• Script mode: execute .isr line-by-line (insyra run script.isr)

Official user-facing documentation:

• CLI + DSL Guide (unified CLI + REPL + .isr + Go DSL guide)
• Source of truth: prioritize the latest content in the linked document above.

Programmatic DSL API (inside Go code)

Use engine/dsl public API when you want to execute DSL directly from your Go program without entering interactive REPL.

package main

import (
  "fmt"

  "github.com/HazelnutParadise/insyra/engine/dsl"
)

func main() {
  session, err := dsl.NewSession("default", nil)
  if err != nil {
    panic(err)
  }

  if err := session.Execute("newdl 1 2 3 as x"); err != nil {
    panic(err)
  }
  if err := session.Execute("mean x"); err != nil {
    panic(err)
  }

  fmt.Println("vars:", len(session.Context().Vars))
}

Notes:

• Execute accepts the same DSL syntax as REPL / .isr lines.
• ExecuteFile runs a .isr file directly in-process and returns line-numbered errors.
• State/history are persisted after each successful command.
• Empty line and # comment line are ignored.

Agent workflow (recommended)

1. Confirm whether the user wants REPL, one-shot CLI, or .isr script.
2. If isolation is needed, create/select environment first (--env <name> or env open <name>).
3. Use newdl/newdt/load/read to prepare data.

• For Parquet partial reads, prefer load parquet <file> cols <c1,c2,...> rowgroups <i1,i2,...> [as <var>].

4. Apply transforms/stats/model/plot commands.
5. Persist outputs (save, env export) and provide reproducible command history.

Runtime guardrails

• Prefer deterministic commands over ad-hoc manual REPL edits when reproducibility matters.
• For shell variables in PowerShell, remind users to quote names like $result as "$result".
• Use help (or help <command>) when syntax is uncertain.
• For environment restore:
  • env import <file> [name] [--force]
  • Import to a non-empty target fails unless --force is provided.

.isr script syntax (implemented by run command)

.isr is a plain text command list executed line-by-line.

Rules:

• Empty lines are ignored.
• Lines beginning with # are comments.
• Tokens are split by spaces/tabs.
• Single and double quotes are supported.
• Backslash escapes are supported.
• Parsing errors on a line do not stop the whole script; CLI reports line error and continues.

Example:

# sample.isr
newdl 1 2 3 4 5 as x
mean x
rank x as rx
show rx

Run:

insyra run sample.isr

How to use each command

For every command usage syntax (one-by-one), use:

• references/cli-command-usage.md
• references/cli-command-guide.md (recommended: by-topic + one example per command)

This file contains, for each command:

• description
• exact Usage: syntax (from insyra help <command>)
• expanded full forms for shorthand commands such as ttest, ztest, anova, ftest, chisq, regression, fetch, and plot

Fast command templates

# Create isolated environment
insyra env create exp1
insyra --env exp1 newdl 10 20 30 as x
insyra --env exp1 mean x

# Export / import environment bundle
insyra env export exp1 ./exp1.json
insyra env import ./exp1.json exp1-copy --force

# Run script in environment
insyra --env exp1 run ./pipeline.isr

Reference priority for agents

When command behavior and docs conflict, trust in this order:

1. cli/commands/*.go implementation
2. insyra help output
3. README command examples
