add
Prompt for transactions and add them to the journal. Any arguments will
be used as default inputs for the first N prompts.

_FLAGS

Many hledger users edit their journals directly with a text editor, or
generate them from CSV. For more interactive data entry, there is the
add command, which prompts interactively on the console for new
transactions, and appends them to the journal file (if there are
multiple -f FILE options, the first file is used.) Existing transactions
are not changed. This is the only hledger command that writes to the
journal file.

To use it, just run hledger add and follow the prompts. You can add as
many transactions as you like; when you are finished, enter . or press
control-d or control-c to exit.

Features:

-   add tries to provide useful defaults, using the most similar (by
    description) recent transaction (filtered by the query, if any) as a
    template.
-   You can also set the initial defaults with command line arguments.
-   Readline-style edit keys can be used during data entry.
-   The tab key will auto-complete whenever possible - accounts,
    descriptions, dates (yesterday, today, tomorrow). If the input area
    is empty, it will insert the default value.
-   If the journal defines a default commodity, it will be added to any
    bare numbers entered.
-   A parenthesised transaction code may be entered following a date.
-   Comments and tags may be entered following a description or amount.
-   If you make a mistake, enter < at any prompt to go one step
    backward.
-   Input prompts are displayed in a different colour when the terminal
    supports it.

Example (see the tutorial for a detailed explanation):

$ hledger add
Adding transactions to journal file /src/hledger/examples/sample.journal
Any command line arguments will be used as defaults.
Use tab key to complete, readline keys to edit, enter to accept defaults.
An optional (CODE) may follow transaction dates.
An optional ; COMMENT may follow descriptions or amounts.
If you make a mistake, enter < at any prompt to go one step backward.
To end a transaction, enter . when prompted.
To quit, enter . at a date prompt or press control-d or control-c.
Date [2015/05/22]: 
Description: supermarket
Account 1: expenses:food
Amount  1: $10
Account 2: assets:checking
Amount  2 [$-10.0]: 
Account 3 (or . or enter to finish this transaction): .
2015/05/22 supermarket
    expenses:food             $10
    assets:checking        $-10.0

Save this transaction to the journal ? [y]: 
Saved.

On Microsoft Windows, the add command makes sure that no part of the
file path ends with a period, as that would cause problems (#1056).
