I'm looking to develop an alternative to an existing piece of code that reads
email parts into byte slices and then returns these after decoding.
As library users may not wish to use these email parts and because there a

Hi. I have written a small package with an example which runs fine locally, but
doesn't work through the web interface of either my local godoc or pkg.go.dev.

I've been playing with with rangefunc experiment, with help from

out of it (https://blog.perfects.engineering/go_range_over_funcs is a good

I've made an http middleware that uses http.MaxBytesReader to limit the
accepted size of requests.
The middleware is as follows:
func bodyLimitMiddleware(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
r.Body = http

This email follows my email yesterday "cannot convert fs.FS zip file to

Following that, I'm interested to learn how people negotiate interface

I have a program that needs to work equally for a directory of files or for the
contents of a zip file, so I'm using an fs.FS to abstract the two.
Some of the files need to be provided to a PDF importer that accepts an
io.ReadSeeker (#1).
Generally this is working fine except when trying to co

I have a command line programme that can output to either stdout or a named
file. Output to stdout, as commented out in the small example below, works
fine, but not to a named file.

I'm trying to work out why I have a data race problem (on go 1.15 and 1.16).
*SearchResults.Set is called from several goroutines. I am trying to avoid
concurrent access to its two maps using a mutex, but this isn't working.
