I think we may need a little bit more Clarity here on your question...
Evernote is fine, but its text editor
is strange and not good for storing
code snippets. The fact that is allows
HTML but can only manipulate a subset
of HTML is a bit frustrating.
Is there any way to edit Evernote
snippets outside of Evernote?
My first read thru suggests this:
Copy and Paste the Evernote text into
TextEdit, or another editor of your
choice. Clean it up, modify it to
your pleasure... Then Copy & Paste it
back into Evernote.
But I maybe misunderstanding your question... Do you mean to edit the Evernote data without using Evernote? The data is stored in ~\Library\Application Support\Evernote
The Evernote.sql file is presumably the SQL database that stores the tags, sync information, etc...
The Content folder is broken up into individual folders, in my case, marked PXX where XX is a number... Inside each folder is an filename.ENML, filename.html, & thumbnail files.
The ENML appears to be an XML file with the contents of the note. The content.html appears to be a straight HTML file of the content, and the thumbnail files are thumbnail views...
I modified the XML file, and the evernote client did not see the changes... So I presume you can modify the data, but without reverse engineering the database, you can't force the client to sync the changed data....
