[DEPRECATED] - Being able to compile the contents of external files into a Go binary is still useful but there’s now an official way to accomplish this functionality. At this point you should be using a version of Go greater than v1.16, so the Standard Library’s embed package. The Go Team’s release announcement for v1.16 also includes a link to this blog post which provides more information on how to use this library.
Turns text file contents into Go constants.
When you’re writing code that includes text constants for SQL or other structured text as constants, you don’t get the benefit of your IDE or text editors syntax high-lighting. This program simply reads the contents of one or more text files and generates a file (per package) that contains constants assigned to these constants.
Install this package from source using the following command:
go install -v github.com/PennState/fileconst/cmd/fileconst@<version>There are a couple conventions used to make this processing easier:
-
The filename becomes the constant name
-
The (Go single-line style) top-of-block comment in the file becomes the top-of-block comment for the resulting constant.
Once you’ve installed fileconst, add the following Go directive
//go:generate fileconst -dir ./sql -ext sqlThis command indicates that all files with the extension sql in the
subdirectory ./sql should be converted into Go constants. If your
package has a doc.go file that’s an ideal spot to add this directive.
the resulting Go file will be placed in the package’s directory and will
be named fileconst_gen.go.
