remark-obsidian-flavoured-footnotes

A remark plugin that parses a file searching for Obsidian-style footnotes markup, and then creates a footnotes section at the end of the AST. Footnotes are created by typing ^[Footnote content] wherever one desires, so that the writer does not break her line of thought and never has to bother about the right indexes : they are automatically computed by the plugin. For instance, the following Markdown paragraph :

Lorem ipsum odor amet^[Von Dughâto, P. (1922). *Un Livre exceptionnel*. pp. 110-117], consectetuer adipiscing elit.
Est magnis cras auctor donec netus vel mus. Elementum quisque massa risus aliquet class dictum consequat. Nostra nam finibus orci senectus orci orci^[*Ibid*. p. 137] aenean neque.
Est luctus bibendum magnis fames lobortis. Justo leo pharetra lacinia et bibendum elementum eget varius.^[*Ibid*. p. 284] Rhoncus consectetur massa vehicula tellus habitasse non tempor congue. Est dignissim justo vulputate interdum elit. Vel ad viverra fermentum augue integer cubilia neque pretium.

... will yield the following abstract syntax tree (AST) :
