        <script type='text/javascript'>
        document.ANALYSIS_DATA = ;
        document.CALLGRAPH = ;
        </script>



                <p>
Package main provides logic ...
</p>

why I didn't see my other document ? and why the <p> for the package has spaces

// Package main provides logic.
package main
import (

}

some types.....

func main() {
}

// doLogic .....
// .....
// ....
func (sm *myI) doLogic (s *myStruct) bool {

}

Solution

Unexported identifiers are not documented by default. Set at least ?m=all to see them:

The presentation mode of web pages served by godoc can be controlled with the "m" URL parameter; it accepts a comma-separated list of flag names as value:
all     show documentation for all declarations, not just the exported ones
methods show all embedded methods, not just those of unexported anonymous fields
src     show the original source code rather then the extracted documentation
For instance, https://golang.org/pkg/math/big/?m=all shows the documentation for all (not just the exported) declarations of package big. https://godoc.org/golang.org/x/tools/cmd/godoc
