episode idea: handling multipart mails (html+text)

[chmike]

I can’t find a tutorial to create multipart mails with a text part and an utf-8 base64 encoded html part by using the standard library. The best I could find is this but it doesn’t seam to produce a valid mime encoding. An example using templates would be great.

My use case is the following. My Go program is doing a batch processing (e.g. backup, data integrity check, ...) and sends a report by mail. I have a python code that run every night and produce a text only report. When the report is long, it’s hard to locate the problems. I would now like to write the code in Go (because I can), and I’m stuck at generating a multipart mail with problems shown in red in the html part.

Another use case could be to send a multipart mail containing markdown text and its html encoding. The user would provide the markdown text.
