This is an unofficial fix to the Code2HTML plugin used in JEdit, for Isabelle. Fixes:
- Used package xcolor instead of color.
- Abandoned the old package \usepackage[latin1]{inputenc} for encoding special characters from Isabelle; instead, used a combination of \setmainfont{Latin Modern Roman}, \setmathfont{Latin Modern Math}, and \setmonofont{JetBrains Mono} to display special characters. Accordingly, the compiler uses XeLaTeX instead of pdfLaTeX.
- Fixed the indentation problem from the old version.
- In GenericDocument.Java there was a repeated call to the style constructors, resulting in a repeated style definition export in the LaTeX script generated. This was fixed by adding a style detection method.
Note: local building requires local jedit.jar and docbook-xsl-1.49
Since this is an unofficial fix, installation involves replacing the Code2HTML JAR file in JEdit.
-
Ensure Code2HTML is already present in the plugin list. If not, you can download it via the plugin manager. This should be installed by default when Isabelle2025 is installed.
-
Navigate to Isabelle2025/contrib/jedit-20250215/jedit5.7.0-patched/jars, replace the original Code2HTML JAR file with your own compiled fixed Code2HTML JAR file or the compiled Code2HTML JAR file in the repo (make sure the name is Code2HTML.jar).
-
Restart Isabelle2025 to load the plugin. In the plugin manager, you should now see in the Author information, a new bracket that says: (updated by Xuanwei Ren).
