Gumtree can't compare C files

[Yinming-Wang]

I have installed cgum and run it successfully,but when I try to use gumtree to compare c file,it tell me error.(addition:I have tested java file and cpp file,they run very well).This is the error information:Error while running client 'textdiff'.
java.io.IOException: Cannot run program "tree-sitter-parser.py" (in directory "/tmp"): error=2, No such file or directory

Hi!

You can list all AST generators with the following command :

gumtree list GENERATORS

Then you can force using a particular generator using the -g option with the id of the AST generator

i.e.

gumtree webdiff foo.java bar.java -g java-treesitter-ng

The cgum parser is not maintained therefore I do not recommend it, however you can try the c-treesitter-ng parser.

Cheers!
