This defaults to "." if no argument is specified. OPTIONS --as-file-descriptor-set[=false] Output as a google.protobuf.FileDescriptorSet instead of an image Note that images are wire compatible with FileDescriptorSets, but this flag strips the additional metadata added for Buf usage --config="" The buf.yaml file or data to use for configuration --disable-symlinks[=false] Do not follow symlinks when reading sources or configuration from the local filesystem By default, symlinks are followed in this CLI, but never followed on the Buf Schema Registry --error-format="text" The format for build errors printed to stderr. Must be one of [text,json,msvs,junit,github-actions,gitlab-code- quality] --exclude-imports[=false] Exclude imports. --exclude-path=[] Exclude specific files or directories, e.g. "proto/a/a.proto", "proto/a" If specified multiple times, the union is taken --exclude-source-info[=false] Exclude source info --exclude-source-retention-options[=false] Exclude options whose retention is source -h, --help[=false] help for build -o, --output="/dev/null" The output location for the built image. Must be one of format [binpb,json,txtpb,yaml] --path=[] Limit to specific files or directories, e.g. "proto/a/a.proto", "proto/a" If specified multiple times, the union is taken --type=[] The types (package, message, enum, extension, service, method) that should be included in this image. When specified, the resulting image will only include descriptors to describe the requested types. A type name may end with ".**" to recursively include the named element and everything nested beneath it, such as a package and all of its sub-packages OPTIONS INHERITED FROM PARENT COMMANDS --debug[=false] Turn on debug logging --log-format="color" The log format [text,color,json] --timeout=0s The duration until timing out, setting it to 0 means no timeout SEE ALSO buf(1) HISTORY 2026-07-17 Auto generated by spf13/cobra Auto generated by spf13/cobra 2026-07-17 Buf(1)
