From 74211a3c029a157dbd9499b3fe1d29333a8a3a1d Mon Sep 17 00:00:00 2001 From: William Carroll Date: Fri, 7 Feb 2020 21:33:08 +0000 Subject: Support serde for Monzo and YNAB transaction structs Define transaction structs for both Monzo and YNAB. Each package has a `main` function that runs some shallow but preliminary round-trip tests for the serializers and decoders. The fixtures.json file that each of them is referencing has been ignored in case either contains confidential data of which I'm unaware. --- .gitignore | 4 ++- monzo_ynab/monzo/serde.go | 82 +++++++++++++++++++++++++++++++++++++++++++++++ monzo_ynab/ynab/serde.go | 52 ++++++++++++++++++++++++++++++ 3 files changed, 137 insertions(+), 1 deletion(-) create mode 100644 monzo_ynab/monzo/serde.go create mode 100644 monzo_ynab/ynab/serde.go diff --git a/.gitignore b/.gitignore index 83bf215fa9b4..b1338507721e 100644 --- a/.gitignore +++ b/.gitignore @@ -25,4 +25,6 @@ Vundle.vim #
