Extensión de VSCode para el análisis visual de ISCLOGs

#デバッグ #VSCode #HealthShare #InterSystems IRIS

Los ISCLOGs son una herramienta útil de depuración proporcionada con IRIS que os puede ayudar a solucionar muchos tipos de problemas. Para obtener más información sobre cómo generar estos registros, consultad la siguiente documentación de IRIS: "Logging".

Este registro se escribe en el global ^ISCLOG almacenado en el espacio de nombres %SYS. Cada nodo de esta global representa un evento independiente, y en algunos casos, se registra información adicional en los subnodos.

Cada entrada consiste en una lista con los siguientes campos: ID, Categoría, Nivel de Registro (LogLevel), Mensaje, Espacio de Nombres, ID de Proceso, Rutina, ID de Sesión, Etiqueta y Hora de Adición. Para más detalles sobre los distintos campos, consultad la sección "Fields in the Log" en la documentación de IRIS.

Aunque esta herramienta proporciona información valiosa, también genera muchas entradas, lo que puede dificultar su interpretación. Para facilitar su lectura, he creado una extensión para VSCode que mejora la visualización de dos maneras:

1) Al exportar un ISCLOG a VSCode, podéis utilizar funciones integradas como la comparación de archivos.  

2) La utilidad incluye resaltado sintáctico para facilitar la identificación de los diferentes campos.

Instalación:

  1. En VSCode, buscad la extensión "Pretty ISCLOGs" o utilizad el siguiente enlace: Pretty ISCLOGs en Visual Studio Marketplace
  2. Seleccionad el botón de instalar para cargar la extensión.
  3. Seguid los pasos a continuación para exportar y visualizar un ISCLOG:

Uso:

  1. En el ObjectScript Shell, navegad al espacio de nombres "%SYS".
  2. Ejecutad el siguiente comando para especificar un nombre de archivo (podéis usar cualquier nombre, siempre que tenga la extensión ".isclog"):

set file = <filepath>/filename.isclog

ie: set file="C:/ISCLOGs/myISCLOG.isclog"

  1. Ejecutad el siguiente comando para exportar el global ^ISCLOG al archivo:

Open file: "wns" use file zw ^ISCLOG close file

  1. Abrid el archivo en VSCode para visualizar el registro.

Aquí tenéis un ejemplo de captura de pantalla utilizando el tema de color InterSystems Default Dark Modern:

Limitaciones:

Debido a cambios en el almacenamiento de los ISCLOGs, esta utilidad solo funcionará con versiones más recientes (generalmente, versiones de IRIS desde 2018 en adelante).

He probado esto utilizando los estilos visuales proporcionados en la extensión InterSystems ObjectScript. La utilidad usa los colores de los tokens de VSCode. Los colores exactos dependerán del tema visual que tengáis aplicado, por lo que la legibilidad puede variar según el tema elegido.

WSGI サポートの概要

#GitHub #Python #REST API #名前空間 #管理ポータル #InterSystems IRIS

wsgi_logo

コンテキスト

ウェブサーバーゲートウェイインターフェース（WSGI）は、ウェブサーバーがリクエストを Python プログラミング言語で記述されたウェブアプリケーションまたはフレームワークに転送するための単純な呼び出し規則です。 WSGI は PEP 3333 で詳しく説明された Python 規格です。

🤔 定義は良いとして、IRIS との関連性は何でしょうか？

IRIS 2024.2+ の新機能により、直接 IRIS で WSGI アプリケーションを実行できます。 この機能は、IRIS を他の Python フレームワークとライブラリに統合する優れた方法です。

Beta Testers Needed for our Upcoming InterSystems IRIS Developer Professional Certification Exam

#認証 #ObjectScript #SQL #InterSystems IRIS #InterSystems IRIS for Health

Hello IRIS community,  

InterSystems Certification is developing a certification exam for InterSystems IRIS Developer professionals, and if you match the exam candidate description given below, we would like you to beta test the exam. The exam will be available for beta testing on March 5, 2025, and the beta testing must be completed by April 20, 2025. 

 

What are my responsibilities as a beta tester? 

You must schedule and take the exam by April 20, 2025. The exam will be administered in an online proctored environment free of charge (the standard fee of $150 per exam is waived for all beta testers). The InterSystems Certification team will then perform a careful statistical analysis of all beta test data to set a passing score for the exam. The analysis of the beta test results will take 6-8 weeks, and once the passing score is established, you will receive an email notification from InterSystems Certification informing you of the results. If your score on the exam is at or above the passing score, you will have earned the certification!  

Note: Beta test scores are completely confidential. 

Interested in participating? Read the Exam Details and Instructions below:
