1. Export your functions from Ghidra using the following script:
Running this script will export all named functions in the current program to a wikitext file:


<syntaxhighlight lang="c" lines>
<syntaxhighlight lang="c" lines>
Line 24: Line 24:
// * Ignores thunks and FUN_ functions
// * Ignores thunks and FUN_ functions


// List function names and entry point addresses to a file in JSON format
// List function names and entry point addresses to a file in wikitext format
//@category Functions
//@category Functions

2. Convert the JSON file you got to WikiText using the following Python script:
<syntaxhighlight lang="python" lines>
# Point this at the .json file generated by Boktai_ExportFunctionInfoScript.java
import json
import sys
with open(sys.argv[1]) as f:
    fns = json.load(f)
for f in fns:
    name = f["name"]
    sig = f["signature"]
    addr = int(f["entry"], 16)
    print( "|-")
    print(f"| 0x{addr:08x} || {sig}")
</syntaxhighlight>
