Until recently, I have been using the old Opera Mail client for my work email. Opera Mail 12 was released in 2013<\/a>. Being almost ten years old by now, it is starting to show its age with lack of support for newer standards. Since I really like the way the Opera Mail client works, I was really looking forward to the work done by the amazing Vivaldi team (where a lot of my old colleagues from Opera Software ended up, together with a lot of other amazing people), on their Vivaldi Mail client<\/a>.<\/p>\n\n\n\n

As my $DAYJOB uses Microsoft 365 for their email, we have several Outlook users in the house, and sometimes I happen upon a forwarded email sent in .eml format, and while Vivaldi actually uses this format to store email internally, it cannot display an attachment in this format<\/a> (at least not as of October 2022). An eml file is basically just a bare email message, so it should be easy to read, right? Apparently, not so much. Googling around mostly recommended installing Thunderbird and import it there<\/a>. That question did have an interesting answer recommending mhonarc, using it to convert to HTML. I ended up expanding on that, writing a script that converts to HTML and then calls back to my stand-alone Vivaldi e-mail instance. I have this as \/home\/peter\/bin\/eml-viewer<\/em> (if you’re using the main instance, remove the –user-data stuff, otherwise replace it with a path to your configuration directory):<\/p>\n\n\n

\n#!\/bin\/bash\nif [ ! -e "$1" ]; then\n    echo 'eml-viewer file.eml'\n    exit 1\nfi\nOUT=$(mktemp --suffix .html)\n\/bin\/mhonarc -single "$1" > "$OUT"\n\/bin\/vivaldi-stable --user-data-dir=\/home\/peter\/.config\/vivaldi-standalone "$OUT"\n<\/pre><\/div>\n\n\n
<\/div><\/div>\n\n\n\n
The next step is to connect this up to open .eml files. For this, we need to create a matching .local\/share\/applications\/eml-viewer.desktop<\/em> file:<\/p>\n\n\n
\n[Desktop Entry]\nVersion=1.0\nName=EML Viwer\nGenericName=EML Viewer\nComment=View Outlook EML file\nExec=\/home\/peter\/bin\/eml-viewer %U\nStartupNotify=false\nTerminal=false\nIcon=mail-mark-unread\nType=Application\nCategories=Viewer;\nMimeType=message\/rfc822;\n<\/pre><\/div>\n\n\n
And finally, make it the default application for opening eml files:<\/p>\n\n\n
\nxdg-mime default eml-viewer.desktop message\/rfc822\n<\/pre><\/div>\n\n\n
This will leave the temporary HTML files in your temporary directory, so take care about sensitive data if on a shared computer. Set $TMPDIR to somewhere private and clear it periodically.<\/p>\n","protected":false},"excerpt":{"rendered":"
