Library and binaries to parse relatively complex Ledger files, and provide an abstract syntax tree (a full programmatic representation of the file), to be able to tweak some parts programmatically, and then write back the files to disk.
ledger-goprovides a few tools to interact with Ledger files, such as balance reports.
ledgerfmt, similar to
gofmt, parses the input file, indents and aligns according to conventions, and outputs the file back, without any semantic changes or interpretation of the data.
ledger2jsonparses your Ledger file and outputs a
.jsonfile, which you can manipulate with any software.
go get -u github.com/abourget/ledger/cmd/...
This implementation has a few limitations compared to the C++ version:
- The current implementation does not validate any balances. It merely acts on the text of the file.
- It does not yet support all top-level constructs, like "account", "alias", "P", "D", "year" / "Y", etc.. Most of those should be simple to implement.
- It does not yet understand tags. They are only considered comments.
- It does not yet implement the
value_exprlanguage that allows you to do complex math computations directly in the postings of your transactions. It merely store the string text of the expression, PROVIDED it is enclosed in parenthesis, e.g.
(123 + 2 * 3 USD).
