Tool for generating OpenTelemetry tracing decorators.
go get -u github.com/KazanExpress/tracegen/cmd/...tracegen generates OpenTelemetry tracing decorators.
It scans the public interfaces in the specified source file and generates a
decorator for each one. Use @trace annotation in the method doc to specify the
traceable parameters (comma separated list). You can access nested fields and
types (Array, Bool, Int,Int64, Float64, String, Unknown). If no type is
specified, Unknown will be used by default. Values with Unknown type will be
JSON encoded or formatted to string, according to the Go formatting rules, if
the former is not possible. Example: "@trace Int64:id".
Requirements and restrictions:
- each interface method must have "ctx context.Context" parameter;
- don't combine parameters of the same type (for example "Do(a, b string)");
Params:
-destination string
Output file; defaults to stdout.
-source string
Input file; defaults to $GOFILE.
See examples and tests for more information.
