Grammar for the CSV conversion rules, more or less:

RULES: RULE*

RULE: ( FIELD-LIST | FIELD-ASSIGNMENT | CONDITIONAL-BLOCK | SKIP | NEWEST-FIRST | DATE-FORMAT | COMMENT | BLANK ) NEWLINE

FIELD-LIST: fields SPACE FIELD-NAME ( SPACE? , SPACE? FIELD-NAME )*

FIELD-NAME: QUOTED-FIELD-NAME | BARE-FIELD-NAME

QUOTED-FIELD-NAME: " (any CHAR except double-quote)+ "

BARE-FIELD-NAME: any CHAR except space, tab, #, ;

FIELD-ASSIGNMENT: JOURNAL-FIELD ASSIGNMENT-SEPARATOR FIELD-VALUE

JOURNAL-FIELD: date | date2 | status | code | description | comment | account1 | account2 | amount | JOURNAL-PSEUDO-FIELD

JOURNAL-PSEUDO-FIELD: amount-in | amount-out | currency

ASSIGNMENT-SEPARATOR: SPACE | ( : SPACE? )

FIELD-VALUE: VALUE (possibly containing CSV-FIELD-REFERENCEs)

CSV-FIELD-REFERENCE: % CSV-FIELD

CSV-FIELD: ( FIELD-NAME | FIELD-NUMBER ) (corresponding to a CSV field)

FIELD-NUMBER: DIGIT+

CONDITIONAL-BLOCK: if ( FIELD-MATCHER NEWLINE )+ INDENTED-BLOCK

FIELD-MATCHER: ( CSV-FIELD-NAME SPACE? )? ( MATCHOP SPACE? )? PATTERNS

MATCHOP: ~

PATTERNS: ( NEWLINE REGEXP )* REGEXP

INDENTED-BLOCK: ( SPACE ( FIELD-ASSIGNMENT | COMMENT ) NEWLINE )+

REGEXP: ( NONSPACE CHAR* ) SPACE?

VALUE: SPACE? ( CHAR* ) SPACE?

COMMENT: SPACE? COMMENT-CHAR VALUE

COMMENT-CHAR: # | ;

NONSPACE: any CHAR not a SPACE-CHAR

BLANK: SPACE?

SPACE: SPACE-CHAR+

SPACE-CHAR: space | tab

CHAR: any character except newline

DIGIT: 0-9

--- ** reading csv files

-- | Read a Journal from the given CSV data (and filename, used for error
-- messages), or return an error. Proceed as follows:
--
-- 1. parse CSV conversion rules from the specified rules file, or from
--    the default rules file for the specified CSV file, if it exists,
--    or throw a parse error; if it doesn't exist, use built-in default rules
--
-- 2. parse the CSV data, or throw a parse error
--
-- 3. convert the CSV records to transactions using the rules
--
-- 4. if the rules file didn't exist, create it with the default rules and filename
--
-- 5. return the transactions as a Journal
