* Add functionality to export proto files
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.
* Refactor file creation error handling
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.
* Update 'proto-out' command to 'proto-out-dir'
The command for exporting proto files and setting the output directory has been updated from 'proto-out' to 'proto-out-dir'. This change has been made both in the README and the grpcurl go file. This makes the command name more descriptive, accurately reflecting its functionality.
* fix import sort
* Reorder file close operation in error handling
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.
* Update grpcurl commands in README
The grpcurl commands for exporting proto files and protoset files in the README are updated. The IP address has been changed to localhost and port number to '8787'. Also, the service name is adjusted to 'my.custom.server.Service'. Instructions for use of specific command options are added for enhanced clarity.
* Refactor error handling in file creation
The code responsible for error handling during file creation in the desc_source.go file has been streamlined. This modification simplifies the code by reducing unnecessary condition checks and redundant file closure action after an error has occurred.
* Refactor proto file writing into separate function
The file writing process for protobuf files has been extracted into a new function called writeProtoFile(). This refactoring simplifies the main function. The code is cleaner and more manageable this way, improving maintainability and readability.
* Refactor writeProtoFile function for better error handling
Streamlined the writeProtoFile function in desc_source.go file. Simplified path calculations and improved error messages for file-creation functions, making it easier to trace the exact point of failure and enhance the debugging process.
* update to latest jhump/protoreflect
* be lenient when possible if server cannot furnish all dependencies
* move linting back to go 1.21 instead of latest go 1.22
* make staticcheck happy
* organize into multiple files
* make listing methods show fully-qualified names
* address small feedback from recent change (trim then check if empty)
