After go1.16, go will use module mode by default, even when the repository is checked out under GOPATH or in a one-off directory. Add go.mod, go.sum to keep this repo buildable without opting out of the module mode. > go mod init github.com/mmcgrana/gobyexample > go mod tidy > go mod vendor In module mode, the 'vendor' directory is special and its contents will be actively maintained by the go command. pygments aren't the dependency the go will know about, so it will delete the contents from vendor directory. Move it to `third_party` directory now. And, vendor the blackfriday package. Note: the tutorial contents are not affected by the change in go1.16 because all the examples in this tutorial ask users to run the go command with the explicit list of files to be compiled (e.g. `go run hello-world.go` or `go build command-line-arguments.go`). When the source list is provided, the go command does not have to compute the build list and whether it's running in GOPATH mode or module mode becomes irrelevant.

The Pygments MoinMoin Parser
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This is a MoinMoin parser plugin that renders source code to HTML via
|
|
Pygments; you need Pygments 0.7 or newer for this parser to work.
|
|
|
|
To use it, set the options below to match your setup and put this file in
|
|
the data/plugin/parser subdirectory of your Moin instance, and give it the
|
|
name that the parser directive should have. For example, if you name the
|
|
file ``code.py``, you can get a highlighted Python code sample with this
|
|
Wiki markup::
|
|
|
|
{{{
|
|
#!code python
|
|
[...]
|
|
}}}
|
|
|
|
Additionally, if you set ATTACHMENTS below to True, Pygments will also be
|
|
called for all attachments for whose filenames there is no other parser
|
|
registered.
|
|
|
|
You are responsible for including CSS rules that will map the Pygments CSS
|
|
classes to colors. You can output a stylesheet file with `pygmentize`, put
|
|
it into the `htdocs` directory of your Moin instance and then include it in
|
|
the `stylesheets` configuration option in the Moin config, e.g.::
|
|
|
|
stylesheets = [('screen', '/htdocs/pygments.css')]
|
|
|
|
If you do not want to do that and are willing to accept larger HTML
|
|
output, you can set the INLINESTYLES option below to True.
