hgen

H-files generator

Inspired by headscan https://cs.opensource.google/go/go/+/refs/tags/go1.17.1:src/go/doc/headscan.go

There is a simple tool for generating header files for C lang API. Based on scanned sources it creates <packagename>.h files with definitions for exported constants.

Usage

Just build and run with --folders option.

$ go build . && ./hgen --folders ../../../sdk/transit && head transit.h
7:24PM INF main.go:55 > starting cfg={"Folders":["../../../sdk/transit"],"NoPrefix":false,"Verbose":2}
7:24PM INF main.go:76 > create file fname=transit.h
#ifndef TRANSIT_H
#define TRANSIT_H

#define TRANSIT_REGEX "Regex"
#define TRANSIT_SYNTHETIC "Synthetic"
#define TRANSIT_INFORMATIONAL "Informational"
#define TRANSIT_PERFORMANCE "Performance"

Omit build step with go run

$ go run ./libtransit/tools/hgen/ --folders ./sdk/transit
12:14PM INF libtransit/tools/hgen/main.go:55 > starting cfg={"Folders":["./sdk/transit"],"NoPrefix":false,"Verbose":2}
12:14PM INF libtransit/tools/hgen/main.go:76 > create file fname=transit.h
