Re: How to download attachments from *.eml file

[rocuinneagain]

Kdb+ can parse binary files as nicely shown at the recent KX meetup by

https://community.kx.com/t5/Events/KX-Community-Meetup-New-York/ba-p/13880

File formats can get complicated though so this can be a lot of work.

 

If I wanted to do this task quickly I would either:

a) Use a system call to a command line tool to extract the files on disk and then read them in from there.

Writing them to current directory or using mktemp command to write in /var/tmp

b) Wrap some exiting python code using EmbedPy to extract the email and attachments  to JSON and read in to kdb+ this way.

Similar to how I did for XML with https://github.com/rianoc/qXML
