VarWizard
- Introduction
VarWizard is a language model-based tool to help generate more meaningful variable names in source code than the original version. It supports 10 programming languages: c, cpp, java, javascript, go, python, php, c_sharp, ruby, rust.
- Installation
You can easily install this package by the command
pip install varwizard
-
Usage
- Command-line
You can use VarWizard by running the command
varwizard [--model-name {bloom-560m, codet5-base}]
--input INPUT --lang {c,cpp,java,php,go,javascript,ruby,rust,python,c_sharp}
[--output-path OUTPUT_PATH] [--max-input-len MAX_INPUT_LEN]
[--device DEVICE] [--penalty-alpha PENALTY_ALPHA] [--top-k TOP_K] [--max-new-tokens MAX_NEW_TOKENS]
Details for each argument can be found by
varwizard --help

Python API
Another way is to Python methods. Here is a simple example of VarWizard.
from varwizard import VarWizard
model = VarWizard(model_name = "codet5-base")
code = """
static void lsp2poly ( int * var0, const int16_t * var1, int var2 ) { int var3, var4 ; var0 [ 0 ] = 0x400000 ; // 1.0 in (3.22) var0 [ 1 ] = - var1 [ 0 ] << 8 ; // *2 and (0.15) -> (3.22) for ( var3 = 2 ; var3 <= var2 ; var3 ++ ) { var0 [ var3 ] = var0 [ var3 - 2 ] ; for ( var4 = var3 ; var4 > 1 ; var4 -- ) var0 [ var4 ] -= MULL ( var0 [ var4 - 1 ], var1 [ 2 * var3 - 2 ], FRAC_BITS ) - var0 [ var4 - 2 ] ; var0 [ 1 ] -= var1 [ 2 * var3 - 2 ] << 8 ; } }"""
print(model.make_new_code(code, 'cpp', device = 'cuda:0'))
VarWizard produces the output
static void lsp2poly ( int * m_poly, const int16_t * m_h, int m_n ) { int m_i, m_j ; m_poly [ 0 ] = 0x400000 ; // 1.0 in (3.22) m_poly [ 1 ] = - m_h [ 0 ] << 8 ; // *2 and (0.15) -> (3.22) for ( m_i = 2 ; m_i <= m_n ; m_i ++ ) { m_poly [ m_i ] = m_poly [ m_i - 2 ] ; for ( m_j = m_i ; m_j > 1 ; m_j -- ) m_poly [ m_j ] -= MULL ( m_poly [ m_j - 1 ], m_h [ 2 * m_i - 2 ], FRAC_BITS ) - m_poly [ m_j - 2 ] ; m_poly [ 1 ] -= m_h [ 2 * m_i - 2 ] << 8 ; } }
