Adapting existing source code snippets to new contexts
Implementations are described herein for adapting existing source code snippets to new contexts. In various implementations, a command may be detected to incorporate an existing source code snippet into destination source code. An embedding may be generated based on the existing source code snippet, e.g., by processing the existing source code snippet using an encoder. The destination source code may be processed to identify one or more decoder constraints. Subject to the one or more decoder constraints, the embedding may be processed using a decoder to generate a new version of the existing source code snippet that is adapted to the destination source code.
1. A method implemented using one or more processors, comprising:
detecting a command to incorporate an existing source code snippet into destination source code;
generating an embedding based on the existing source code snippet, wherein the generating includes processing the existing source code snippet using an encoder;
processing the destination source code to identify one or more decoder constraints, wherein the one or more decoder constraints comprise a dictionary of variable names or function names extracted from the destination source code;
subject to the one or more decoder constraints, processing the embedding using a decoder to generate a new version of the existing source code snippet that is adapted to the destination source code, wherein processing the embedding using the decoder includes biasing the decoder towards the variable names or function names in the dictionary.
2. The method of claim 1 , wherein the existing source code snippet includes a function call, and processing the embedding using the decoder includes generating glue code to adapt the function call to the destination source code.
3. The method of claim 1 , wherein the command comprises a paste command.
4. The method of claim 1 , wherein the command comprises a command to drag-and-drop a graphical element that includes the existing source code snippet into the destination source code.
5. The method of claim 1 , wherein the generating includes processing at least a portion of the destination source code using the encoder.
6. A method implemented using one or more processors, comprising:
detecting a command to incorporate an existing source code snippet into destination source code;

generating a second embedding based on the destination source code snippet, wherein the generating includes processing data indicative of the destination source code snippet using one or more of the encoders;
combining the first and second embeddings into a combined embedding; and
processing the combined embedding using a decoder to generate a new version of the existing source code snippet that is adapted to the destination source code.
7. The method of claim 6 , wherein the combining comprises concatenating the first and second embeddings.
8. The method of claim 6 , wherein generating the first and second embeddings include processing the existing and destination source code snippets to generate, respectively, first and second abstract syntax trees.

10. The method of claim 6 , wherein the existing source code snippet includes a function call.
11. The method of claim 10 , wherein processing the embedding using the decoder includes generating glue code to adapt the function call to the destination source code.

detect a command to incorporate an existing source code snippet into destination source code;
generate a first embedding based on the existing source code snippet, wherein the generating includes processing data indicative of the existing source code snippet using one or more encoders;
generate a second embedding based on the destination source code snippet, wherein the instructions to generate include instructions to process data indicative of the destination source code snippet using one or more of the encoders;
combine the first and second embeddings into a combined embedding; and
