* 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.
The proper `v1` gRPC reflection has been around for a bit.
The "client auto" mechanism still supports falling back to `v1alpha`.
Not many support the `v1`, but we should default to it when possible.
* Revises the sections that talk about descriptor sources, making them more consistent.
* Adds a link to the Gophercon 2018 talk on grpcurl.
* Improve installation section, mentioning versioned Go.
* add goreleaser
Add a goreleaser configuration file that builds binaries for Linux,
MacOS and Windows, for 32bit (x86/386) and 64bit (x64/amd64). The
binaries will be archived into a tar.gz/zip file along with the LICENSE
file.
The `dist/` directory will be written to by goreleaser with the binaries
during the build process, so it's also been added to .gitignore.
To build all the binaries and release them to GitHub:
1. Tag the release. e.g. `git tag -a v1.0.0 -m 'First release'`
2. Generate a GitHub Personal Access Token. See https://github.com/settings/tokens.
3. Push the release to GitHub. e.g. `git push origin v1.0.0`
4. Make the release, which will publish binaries to the GitHub "Releases" page. e.g. `GITHUB_TOKEN=xxxxxxx... make release`
* add -version flag
Run `grpcurl -version` to see the release version. Use `make install` to build a binary that shows the version based on current git hash (which will show a version number if HEAD is a release tag and otherwise uses `git describe` to summarize the version).
Service reflection has very poor SEO and unfortunately not great discoverability. Since this package is an entry-point for service reflection, this helps make the process of finding this information easier.
