# iris-embedded-python-wrapper

This is a module that wraps embedded python in the IRIS Dataplateform. It provides a simple interface to run python code in IRIS.

More details can be found in the [IRIS documentation](https://docs.intersystems.com/iris20243/csp/docbook/DocBook.UI.Page.cls?KEY=AFL_epython)

# Pre-requisites

To make use of this module, you need to have the IRIS Dataplatform installed on your machine (more details can be found [here](https://docs.intersystems.com/iris20243/csp/docbook/DocBook.UI.Page.cls?KEY=PAGE_deployment_install)).

Then you must configure the [service callin](#configuration-of-the-service-callin) to allow the python code to be executed and [set the environment variables](#environment-variables).

## Configuration of the service callin

In the Management Portal, go to System Administration > Security > Services, select %Service_CallIn, and check the Service Enabled box.

More details can be found in the [IRIS documentation](https://docs.intersystems.com/iris20243/csp/docbook/DocBook.UI.Page.cls?KEY=GEPYTHON_prereqs)

## Environment Variables

Set the following environment variables :

- IRISINSTALLDIR: The path to the IRIS installation directory
- LD_LIBRARY_PATH: The path to the IRIS library
- IRISUSERNAME: The username to connect to IRIS
- IRISPASSWORD: The password to connect to IRIS
- IRISNAMESPACE: The namespace to connect to IRIS

### For Linux and MacOS

For Linux and MacOS, you can set the environment variables as follows:

```bash
export IRISINSTALLDIR=/opt/iris
export LD_LIBRARY_PATH=$IRISINSTALLDIR/bin:$LD_LIBRARY_PATH
# for MacOS
export DYLD_LIBRARY_PATH=$IRISINSTALLDIR/bin:$DYLD_LIBRARY_PATH
# for IRIS username
export IRISUSERNAME=SuperUser
export IRISPASSWORD=SYS
export IRISNAMESPACE=USER
```

### For windows

For windows, you can set the environment variables as follows:
    
```bash
set IRISINSTALLDIR=C:\path\to\iris
set LD_LIBRARY_PATH=%IRISINSTALLDIR%\bin;%LD_LIBRARY_PATH%
```

Update the library path for windows

```bash
set PATH=%IRISINSTALLDIR%\bin;%PATH%
```

Set the IRIS username, password, and namespace

```bash
set IRISUSERNAME=SuperUser
set IRISPASSWORD=SYS
set IRISNAMESPACE=USER
```

### For PowerShell

For PowerShell, you can set the environment variables as follows:

```powershell
$env:IRISINSTALLDIR="C:\path\to\iris"
$env:PATH="$env:IRISINSTALLDIR\bin;$env:PATH"
$env:IRISUSERNAME="SuperUser"
$env:IRISPASSWORD="SYS"
$env:IRISNAMESPACE="USER"
```

## Installation  

```bash
pip install iris-embedded-python-wrapper
```

# Usage

You can use this module in three ways:

1. Run python code in IRIS
2. Bind a virtual environment to embedded python in IRIS
3. Unbind a virtual environment from embedded python in IRIS

## Run python code in IRIS

Now you can use the module to run python code in IRIS. Here is an example:

```python
import iris
iris.system.Version.GetVersion()
```

Output:

```python
'IRIS for UNIX (Apple Mac OS X for x86-64) 2024.3 (Build 217U) Thu Nov 14 2024 17:29:23 EST'
```

## Bind a virtual environment to embedded python in IRIS

You can also bind or unbind an virtual environment to embedded python in IRIS. Here is an example:

```bash
bind_iris
```

Output:

```bash
(.venv) demo ‹master*›$ bind_iris
INFO:iris_utils._find_libpyton:Created backup at /opt/intersystems/iris/iris.cpf.fa76423a7b924eb085911690c8266129
INFO:iris_utils._find_libpyton:Created merge file at /opt/intersystems/iris/iris.cpf.python_merge
up  IRIS              2024.3.0.217.0    1972   /opt/intersystems/iris

Username: SuperUser
Password: ***
IRIS Merge of /opt/intersystems/iris/iris.cpf.python_merge into /opt/intersystems/iris/iris.cpf
IRIS Merge completed successfully
INFO:iris_utils._find_libpyton:PythonRuntimeLibrary path set to /usr/local/Cellar/python@3.11/3.11.10/Frameworks/Python.framework/Versions/3.11/Python
INFO:iris_utils._find_libpyton:PythonPath set to /demo/.venv/lib/python3.11/site-packages
INFO:iris_utils._find_libpyton:PythonRuntimeLibraryVersion set to 3.11
```

You may have to put your admin credentials to bind the virtual environment to the embedded python in IRIS.

In windows, you must restart the IRIS.

## Unbind a virtual environment from embedded python in IRIS

```bash
unbind_iris
```

Output:

```bash
(.venv) demo ‹master*›$ unbind_iris
INFO:iris_utils._find_libpyton:Created merge file at /opt/intersystems/iris/iris.cpf.python_merge
up  IRIS              2024.3.0.217.0    1972   /opt/intersystems/iris

```

# Troubleshooting

You may encounter the following error, here is how to fix them.

## No module named 'pythonint'

This can occur when the environment variable `IRISINSTALLDIR` is not set correctly. Make sure that the path is correct.

## IRIS_ACCESSDENIED (-15)

This can occur when the service callin is not enabled. Make sure that the service callin is enabled.

## IRIS_ATTACH (-21)

This can occur when the user is not the same as the iris owner. Make sure that the user is the same as the iris owner.
