# simple aliases

# 1. simple alias directive
<
alias checking = assets:bank:checking
1/1
    (checking:a)  1
$ hledger -f- accounts
assets:bank:checking:a

# 2. simple alias matches whole account name components only
<
alias a:b = A:B
1/1
    (a:b:c)   1  ; should match this
1/1
    (a:bb:d)  1  ; should not match this
$ hledger -f- accounts
A:B:c
a:bb:d

# 3. a simple alias matching the whole account name works
<
alias a:b = A:B
1/1
    (a:b)   1
$ hledger -f- accounts
A:B

# regular expression aliases

# 4. regex alias directive
<
alias /^(.+):bank:([^:]+):?(.*)/ = \1:\2 \3
1/1
    (assets:bank:B:checking:a)  1
$ hledger -f- accounts

# 5. regex alias pattern is a case-insensitive regular expression
# matching anywhere in the account name. All matching aliases are
# applied to an account name in turn, most recently seen first. The
# replacement can replace multiple matches within the account name.
# The replacement pattern supports numeric backreferences.
