How to get the Markdown Viewer addon of Firefox to work on Linux?
Happy to report that I was able to find a solution that I provided here:
https://github.com/Thiht/markdown-viewer/issues/62#issuecomment-277702230
I've also copied it here for reference:
On Linux, you'll need to create a new MIME type here:
~/.local/share/mime/packages/text-markdown.xml
With the following content:
<?xml version="1.0"?>
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
<mime-type type="text/plain">
<glob pattern="*.md"/>
<glob pattern="*.mkd"/>
<glob pattern="*.markdown"/>
</mime-type>
</mime-info>
Then run:
update-mime-database ~/.local/share/mime
I had to manually edit my ~/.mozilla/firefox/<PROFILE>/mimeTypes.rdf
. This review of the addon says:
For linux users, try to add "md" to .mozilla/*.default/mimeTypes.rdf this line : mdin text/plain section :)
Hmm. I couldn't find a text/plain
section, but I found this page is helpful:
If there is not yet an existing RDF node for 'text/plain' add it, and add "md" as a file extension.
<RDF:Description RDF:about="urn:mimetype:text/plain" NC:value="text/plain" NC:fileExtensions="md" NC:description="Text Document"> <NC:handlerProp RDF:resource="urn:mimetype:handler:text/plain"/> </RDF:Description>
However, what I ended up doing was:
<RDF:Description RDF:about="urn:mimetype:text/plain; charset=utf8"
NC:value="text/plain; charset=utf8"
NC:handleInternal="true"
NC:description="Markdown Document">
<NC:fileExtensions>md</NC:fileExtensions>
<NC:fileExtensions>mkd</NC:fileExtensions>
<NC:fileExtensions>mdown</NC:fileExtensions>
<NC:fileExtensions>markdown</NC:fileExtensions>
<NC:handlerProp RDF:resource="urn:mimetype:handler:text/plain; charset=utf8"/>
</RDF:Description>
It seemed to be the NC:handInternal="true"
that did the trick. Interestingly, it seems it does not work with the text/markdown
or text/x-markdown
MIME types. The charset=utf8
is because I write all my Makefiles in Unicode.
I was able to solve the same problem by putting the following line into ~/.mime.types
.
text/plain md markdown
