Nextion to Text Converter
Description
This script creates a text file for each page of your Nextion GUI, containing all components of the page, including their properties and the entire source code.
This tool was mainly created to get meaningful commit diffs (which is not possible with the binary HMI file) and to allow you to share your source code with other people as easily as developers are used to. Binary files are simply impractical for development and sharing.
This tool can NOT convert text back to a .HMI file.
Usage
The script is written in Python, v3.8. No additional modules are required. The script offers a couple of options to customize its behavior and output. You can get a full description of all command line options with
python Nextion2Text.py -h
For most basic usage, simply run
python Nextion2Text.py -i PATH_TO_HMI_FILE -o FOLDER_FOR_TEXT_FILES
Note that by default, visual properties (x/y position, colors, pictures, fonts, ...) are not included, see example links below.
Features and Limitations
Known to work with files created with editor version 1.60.x and newer. May work with some 0.5x versions.
Supports all Nextion components, including the Intelligent series components - except for the new TouchCap component (only partially supported without attributes).
However, Intelligent series attributes are only partially supported by now. You can use the --properties unknown (See command line help for more details) option to include unknown attributes, too.
Example
The Example folder contains a HMI file, a subfolder with the resultung text files, and a .cmd file that has been executed to generate the text files. In addition, here are some interesting commits you may want to look at:
- How a commit diff looks when the HMI file gets modified
- Visual attributes included
- Visual attributes excluded
- diff between both
