Snipdoc
Snipdoc is a simple tool for maintaining package documentation that contains code samples.
-
Create a subdirectory of your package to hold the following files. "internal" is a good name.
-
Write a template file (for example, "doc.template") with the text of your package documentation. The file should look exactly like you want your doc.go file to look, except for code snippets. Instead of embedding a code snippet, write a line consisting solely of
[NAME]
for your choice of NAME.
-
Write a snippets file (for example, "doc-snippets.go") as a valid Go source file. Begin each snippet you'd like to appear in your package docs with
//[ NAMEand end it with//]. -
Construct your doc.go file with the command
awk -f snipdoc.awk doc-snippets.go doc.templateThe file "sample-makefile" in this directory verifies that the snippets file compiles and safely constructs a doc.go file.
