Hi friends,
Over the past years, I have implemented some hacky bits and pieces of a
txn parser and a writer in Emacs Lisp, and I was thinking about pulling
them together into something coherent and proper and maybe even
publishing it at some point.
However I have a bad habit of re-inventing wheels, so I thought I might
ask if something like this exists already? I had a look at
https://plaintextaccounting.org, as well as searching this mailing list,
but all I found were some parsers written in Rust and some attempts at a
tree-sitter based parser for Beancount (which seemed to be so far
WIP/incomplete, near as I could tell).
I am not aware of any Emacs Lisp implementation of a parse and writer,
but we have beancount-mode https://github.com/beancount/beancount-mode/
which uses the usual regexp based approach to implement a Beancount
major mode. The regexps and functions in beancount.el are usually enough
for implementing the kind of ledger editing functions I need.
I have a tree-sitter Beancount parser that AFAIK is complete and
validating (contrary to other tree-sitter Beancount parsers I've seen,
it correctly uses indentation to distinguish syntactical elements) but I
haven't used it for anything other than playing around yet.
Cheers,
Dan
