The file close operation has been moved within the error handling of the 'PrintProtoFile' function. Previously, it was being executed before this function, now it's executed immediately after. Moreover, an additional close operation has been added after the function success ensuring the file is properly closed in all scenarios.
The code for file creation and error handling in desc_source.go has been refactored. Previously, the file closure operation was executed irrespective of whether the file was created successfully or not. Now, the file will only be closed if it was successfully created, improving error handling.
Added a new function, `WriteProtoFiles` in `desc_source.go` which is used to generate .proto files. The process involves resolving symbols from the descriptor source and writing their definitions to a designated output directory. The corresponding flag `--proto-out` has been included in `grpcurl.go` to allow users to specify the directory path.
