An XML editor called Boomslang was initially developed using wxPython and has now been ported to Textual for terminal use. Users will learn to set up the application by installing necessary packages like Textual and lxml via pip. The interface is designed to resemble the original, offering functionalities for editing XML files, adding nodes, previewing XML, and browsing files. The tutorial outlines essential components such as the main UI, the edit XML screen, and file management workflows.
The transition from using wxPython to Textual allows for a terminal-based XML editor and viewer. It enables users to interact with XML files through a streamlined console interface.
To set up the application, first install the required packages: Textual and lxml, via pip. This can be done using the command: python -m pip install textual lxml.
The user interface development involves designing a similar layout to the original Boomslang, utilizing Textual's features to create an appealing terminal interface.
Key components of the application include the main UI, edit screen for XML, add node functionality, XML preview screen, file browser, and file save dialogs.
