Misc.
rulesFileFor :: FilePath -> FilePath Source #
parseRulesFile :: FilePath -> ExceptT String IO CsvRules Source #
An error-throwing action that parses this file's content as CSV conversion rules, interpolating any included files first, and runs some extra validation checks.
parseAndValidateCsvRules :: FilePath -> Text -> ExceptT String IO CsvRules Source #
An error-throwing action that parses this text as CSV conversion rules and runs some extra validation checks. The file path is for error messages.
expandIncludes :: FilePath -> Text -> IO Text Source #
Look for hledger rules file-style include directives in this text, and interpolate the included files, recursively. Included file paths may be relative to the directory of the provided file path. This is a cheap hack to avoid rewriting the CSV rules parser.
transactionFromCsvRecord :: SourcePos -> CsvRules -> CsvRecord -> Transaction Source #
