A simple implementation of ledger-cli. This implementation only covers a few commands of the original ledger-cli. This project is only for educational purposes. It does not provide any advantages over the original project.
You can use this program as if it was the original ledger-cli, but with a selected group of flags and commands:
./ledger.py [-h] [-v] [-S value-expression] [--price-db FILE] [-f FILE] Action [Action ...]
-
-h
: Displays the usage and description of the program. -
-v
: Displays the current version of the program. -
-S
or--sort
: Sorts the entries. See the--sort
section for more details. -
--price-db
: Currently it has no purpose. See the--price-db
section for more details. -
-f
or--file
: Use the specified file as an input. -
Action
: The first word will be our verb. The verb describes what our program will output. It currently can beregister
,balance
orprint
.The following words will be our filters for which accounts we'll work with. See the filters section for more details.
Let's see this commands in more detail.
Filters can be applied to just see a subset of all of our accounts. To use filters, we'll start by describing our keywords:
{x} and {y}
This way, we can filter accounts if they have the text {x}
and {y}
in them.
Examples:
Expenses and Amazon
Income and Job and Encora
{x} or {y}
{x} {y}
Both ways work. We can filter accounts if they have either {x}
or {y}
.
Examples:
Assets Liabilities
Assets and (Bank or Wallet)
not {x}
Filter accounts that DO NOT have {x}
in them.
Examples:
(Liabilities and not Rent) or Expenses
Expenses and not (Drinks or Food)
As you've just read. Every word is treated as a regex. For this project, we are using Python's regex. Feel free to experiment with this function. The only restriction is to not use spaces, as they are our limiters for keywords and such.
Examples:
Income and [^:]+:[^:]+:[^:]+
^Expenses and not .*tion$
Sorry for my poor examples. I don't know about finances. ;-;
This flag can be used multiple times. It indicates the ledger file(s) we will be
working on. If no file is specified, the program will read from standard input
( NOT YET IMPLEMENTED.stdin
).
The --sort
flag will always sort in ascending order. We can sort our
entries in two different ways:
date
ord
: Sort every entry given the date of the transaction.amount
ora
: Sort given the amount of the transaction. This breaks entries into individual transactions.
The --sort
flag will only make changes on the outputs of register
and
print
. The verb balance
will always print in alphabetical order.
It points to the file that contains our prices history.
The original flag for --price-db
is commonly used alongside other flags such
as -V
or --market
, that uses the prices history to convert all amounts into
our default currency. That's why currently this command doesn't have any
function to it. It's yet to know how we will work with this flag.
