# Editing Scripts And Script Libraries

This guide describes how to edit scripts related to a template such as `TestMachine`.

Read `script-parsing.md` first so you know whether the target script is a script library, an object-level script-like attribute, an extension primitive, or content that only appears in an exported object package.

Run commands from `graccess_cli`. Examples assume an active session:

```powershell
graccess session start --galaxy ZB --node .
```

Without a session, add `--node .` to each command.

For LLM-driven script work, read script metadata and validate guarded edits with the LLM envelope:

```powershell
graccess object scripts list --galaxy ZB --name TestMachine --type template --llm-json
graccess object scripts get --galaxy ZB --name TestMachine --type template --script UpdateTestChangingInt --llm-json
graccess object scripts settings set --galaxy ZB --name TestMachine --type template --script UpdateTestChangingInt --trigger-period-ms 500 --confirm --confirm-target TestMachine --dry-run --llm-json
```

## What The CLI Can Edit Today

| Area | Current command support |
|---|---|
| Script library inventory | `script-library list` |
| Script library export | `script-library export` |
| Script library import/add | `script-library import`, `script-library add`, `galaxy import-script-library` |
| Object script metadata | `object scripts list`, `object scripts get` |
| Object script body read | `object scripts get` package fallback for script body attributes such as `ExecuteText` |
| Object script mutable settings | `object scripts settings set --trigger-type`, `--trigger-period-ms` |
| Script-like attributes | `object attribute set`, lock, security, buffer |
| Extension primitives | `object extension add/delete/rename` |
| Full object package script payloads | Use `objects export` and `galaxy import-objects` |

## Export Before Editing

Export script libraries before changing them:

```powershell
$out = '.\template-snapshots\script-libraries-before'
New-Item -ItemType Directory -Force -Path $out | Out-Null

$libs = graccess script-library list --galaxy ZB --json | ConvertFrom-Json
foreach ($lib in $libs) {
  $name = $lib.Name
  $path = Join-Path $out "$name.aaslib"
  graccess script-library export --galaxy ZB --name $name --output $path --confirm --confirm-target $path
}
```

Export the template package when object-level scripts may be involved:

```powershell
$pkg = '.\template-snapshots\TestMachine-before\TestMachine.aaPKG'
graccess objects export --galaxy ZB --type template --name TestMachine --output $pkg --confirm --confirm-target $pkg
```

## Edit Script Libraries

Script library content is edited outside the CLI in the `.aaslib` file or source toolchain that creates it. Import the updated library after review:

```powershell
graccess script-library import --galaxy ZB --path '.\scripts\CommonScripts.aaslib' --confirm --confirm-target '.\scripts\CommonScripts.aaslib'
```

The galaxy-level import command is also available:

```powershell
graccess galaxy import-script-library --galaxy ZB --path '.\scripts\CommonScripts.aaslib' --confirm --confirm-target '.\scripts\CommonScripts.aaslib'
```

After import, list libraries again:

```powershell
graccess script-library list --galaxy ZB --json
```

## Edit Script-Like Attributes

Some templates store expressions, declarations, triggers, or script fragments in attributes. Find candidates:

```powershell
$attrs = graccess object attributes --galaxy ZB --name TestMachine --type template --json | ConvertFrom-Json
$extended = graccess object extended-attributes --galaxy ZB --name TestMachine --type template --json | ConvertFrom-Json
$scripts = (@($attrs) + @($extended)) | Where-Object {
  $_.Name -match '(?i)script|execute|trigger|expression|declaration|startup|shutdown|scan'
} | Sort-Object Name -Unique

$scripts | Select-Object Name, DataType, Category, Locked
```

If the script-like setting is a scalar writable attribute, edit it through the normal template edit flow. Script extension attributes are looked up through `ConfigurableAttributes` first, then `Attributes`.

For local `ScriptExtension` objects, body fields such as `ExecuteText`, `StartupText`, `OnScanText`, and `Expression` are package-only. GRAccess `IAttribute.SetValue` can return success without persisting package-only fields, so `object scripts set` and `object scripts settings set --expression` fail fast when the attribute category starts with `MxCategoryPackageOnly`. Use the IDE or a future package-rewrite path for those fields.

```powershell
graccess object checkout --galaxy ZB --name TestMachine --type template --confirm --confirm-target TestMachine
graccess object attribute value set --galaxy ZB --name TestMachine --type template --attribute SomeWritableScriptSetting --value Updated --data-type string --confirm --confirm-target TestMachine
graccess object save --galaxy ZB --name TestMachine --type template --confirm --confirm-target TestMachine
graccess object checkin --galaxy ZB --name TestMachine --type template --comment 'Update writable script setting' --confirm --confirm-target TestMachine
```

Update periodic script settings and lock the interval for deployment inheritance:

```powershell
graccess object checkout --galaxy ZB --name '$TestMachine' --type template --confirm --confirm-target '$TestMachine'
graccess object scripts settings set --galaxy ZB --name '$TestMachine' --type template --script UpdateTestChangingInt --trigger-period-ms 500 --lock-trigger-period --confirm --confirm-target '$TestMachine'
graccess object save --galaxy ZB --name '$TestMachine' --type template --confirm --confirm-target '$TestMachine'
graccess object checkin --galaxy ZB --name '$TestMachine' --type template --comment 'Set UpdateTestChangingInt interval to 500ms' --confirm --confirm-target '$TestMachine'
```

Verify with package-backed readback:

```powershell
graccess object scripts get --galaxy ZB --name TestMachine --type template --script UpdateTestChangingInt --llm-json
```

## Edit Extension Primitives

When a script is represented by an extension primitive, use the extension commands for the primitive lifecycle:

```powershell
graccess object checkout --galaxy ZB --name TestMachine --type template --confirm --confirm-target TestMachine
graccess object extension add --galaxy ZB --name TestMachine --type template --extension-type ScriptExtension --primitive OnScan --object-extension --confirm --confirm-target TestMachine
graccess object save --galaxy ZB --name TestMachine --type template --confirm --confirm-target TestMachine
graccess object checkin --galaxy ZB --name TestMachine --type template --comment 'Add script extension primitive' --confirm --confirm-target TestMachine
```

Rename:

```powershell
graccess object extension rename --galaxy ZB --name TestMachine --type template --extension-type ScriptExtension --primitive OnScan --new-name OnScan2 --object-extension --confirm --confirm-target TestMachine
```

Delete:

```powershell
graccess object extension delete --galaxy ZB --name TestMachine --type template --extension-type ScriptExtension --primitive OnScan2 --object-extension --confirm --confirm-target TestMachine
```

These commands manage primitive structure. The wrapper below creates the same `ScriptExtension` primitive and can initialize mutable settings:

```powershell
graccess object checkout --galaxy ZB --name '$MyTemplate' --type template --confirm --confirm-target '$MyTemplate'
graccess object scripts create --galaxy ZB --name '$MyTemplate' --type template --script OnScan --trigger-type Periodic --trigger-period-ms 1000 --confirm --confirm-target '$MyTemplate'
graccess object save --galaxy ZB --name '$MyTemplate' --type template --confirm --confirm-target '$MyTemplate'
graccess object checkin --galaxy ZB --name '$MyTemplate' --type template --comment 'Add OnScan script' --confirm --confirm-target '$MyTemplate'
```

After adding a `ScriptExtension` primitive, body text still needs the IDE/package path when the projected body attributes are package-only.

## Full-Fidelity Object Script Edits

When script bodies are only available inside the object package, use export/import:

1. Export the template package.
2. Edit with the supported vendor tooling or package workflow.
3. Import the updated package with explicit confirmation.
4. Re-parse and validate the template.

Export:

```powershell
$pkg = '.\template-work\TestMachine.aaPKG'
graccess objects export --galaxy ZB --type template --name TestMachine --output $pkg --confirm --confirm-target $pkg
```

Import:

```powershell
graccess galaxy import-objects --galaxy ZB --file '.\template-work\TestMachine.aaPKG' --overwrite --confirm --confirm-target '.\template-work\TestMachine.aaPKG'
```

For conflict-aware import:

```powershell
graccess galaxy import-objects-ex --galaxy ZB --file '.\template-work\TestMachine.aaPKG' --version-conflict '<E_RESOLVE_VERSION_CONFLICT_ACTION>' --name-conflict '<E_RESOLVE_NAME_CONFLICT_ACTION>' --confirm --confirm-target '.\template-work\TestMachine.aaPKG'
```

The exact enum values for import conflict handling must match the local GRAccess interop assembly. See `graccess_operations.md` and `graccess_documentation.md`.

## Validate Script Edits

After import or checkin:

```powershell
graccess object get --galaxy ZB --name TestMachine --type template --json
graccess object attributes --galaxy ZB --name TestMachine --type template --json
graccess object extended-attributes --galaxy ZB --name TestMachine --type template --json
```

For runtime validation, instantiate a test object and deploy only that explicitly named test instance:

```powershell
graccess template instantiate --galaxy ZB --name TestMachine --type template --new-name TestMachine_ScriptTest_001 --create-contained --confirm --confirm-target TestMachine
graccess instance deploy --galaxy ZB --name TestMachine_ScriptTest_001 --type instance --confirm --confirm-target TestMachine_ScriptTest_001
```

## Supported Object Script Command Pattern

```text
graccess object scripts list --galaxy ZB --name TestMachine --type template --json
graccess object scripts get --galaxy ZB --name TestMachine --type template --script UpdateTestChangingInt --llm-json
graccess object scripts settings set --galaxy ZB --name TestMachine --type template --script UpdateTestChangingInt --trigger-period-ms 500 --confirm --confirm-target TestMachine --llm-json
```

The local GRAccess examples sometimes show `Template.Scripts[index].ScriptString`, but this repository's installed `ArchestrA.GRAccess.dll` does not expose a public object script collection. It exposes script extension projections as attributes and package records. The CLI can read body text through exported package parsing and can write mutable settings through `IAttribute.SetValue`; package-only body/expression fields are not persisted by that GRAccess setter.
