Interfaz de usuario web moderna para SVN en 2020

cSvn es una interfaz web para repositorios de Subversion . Bases cSvn es script CGI escrito en C .

En mayo de 2020, se publicó el lanzamiento de la próxima versión de Apache Subversion 1.14.0 . A la luz de este evento, se creó una nueva y moderna interfaz web para ver los repositorios de Subversion en cualquier dispositivo. Esta es una noticia muy positiva para aquellos que usan sistemas de control de versiones centralizados debido al hecho de que hasta ayer solo había una interfaz de usuario web decente ( WebSVN ) escrita en PHP y, desafortunadamente, a la zaga de los requisitos modernos.

Este artículo cubre la instalación y configuración de cSvn para que funcione con Nginx + uWsgi . La configuración de los componentes del servidor es bastante simple y prácticamente no difiere de la configuración de cGit .

En el lado del cliente, JavaScript básico se ejecuta con no más de 350 líneas y una hoja de estilo de 24K desempaquetada. Los textos de Markdown se procesan en el lado del servidor utilizando la biblioteca md4c , que se ha probado con éxito en el proyecto KDE Plasma .

En lugar de capturas de pantalla, es mejor mirar un servidor cSvn en ejecución .

Vale la pena señalar que al usar cSvn, puede ver no solo sus propios repositorios, sino también configurar la visualización de recursos de terceros a través de los protocolos HTTPS y SVN.
