tree-cutter: utilities for transforming programs using tree-sitter

inline.py: Inline function calls

Limitations:

• Does not handle expressions which mutate values as arguments
• May produce name clashes between identifiers in the caller and callee code
• Produces ugly transformed code
• Only tested on toy programs so far

Usage

Run the tool and compile the test programs:

python tree_cutter/inline.py test.c foo > test_inline.c
gcc test.c -o test
gcc test_inline.c -o test_inline

Expected output:

$ ./test
1 + 2 = 3
$ ./test_inline
1 + 2 = 3

You can apply multiple transformations at once:

$ cat test_comment.c 
#include "stdlib.h"

int main()
{
    /*foo*/
    foo();
    //bar or baz
    #ifdef BAR
    bar();
    #else
    baz();
    #endif
}
$ python main.py test_comment.c remove_comments remove_preprocessor_directives remove_blank_lines
int main()
{
    foo();
}
