Hledger.Data.StringFormat
Description
Parse format strings provided by --format, with awareness of hledger's report item fields. The formats are used by report-specific renderers like renderBalanceReportItem.
Documentation
parseStringFormat :: String -> Either String StringFormat Source #
Parse a string format specification, or return a parse error.
data StringFormat Source #
A format specification/template to use when rendering a report line item as text.
A format is a sequence of components; each is either a literal string, or a hledger report item field with specified width and justification whose value will be interpolated at render time.
A component's value may be a multi-line string (or a multi-commodity amount), in which case the final string will be either single-line or a top or bottom-aligned multi-line string depending on the StringFormat variant used.
Currently this is only used in the balance command's single-column mode, which provides a limited StringFormat renderer.
Constructors
| OneLine [StringFormatComponent] | multi-line values will be rendered on one line, comma-separated |
| TopAligned [StringFormatComponent] | values will be top-aligned (and bottom-padded to the same height) |
| BottomAligned [StringFormatComponent] | values will be bottom-aligned (and top-padded) |
Instances
data StringFormatComponent Source #
Constructors
| FormatLiteral String | Literal text to be rendered as-is |
| FormatField Bool (Maybe Int) (Maybe Int) ReportItemField | A data field to be formatted and interpolated. Parameters:
|
Instances
data ReportItemField Source #
An id identifying which report item field to interpolate. These are drawn from several hledger report types, so are not all applicable for a given report.
Constructors
| AccountField | A posting or balance report item's account name |
| DefaultDateField | A posting or register or entry report item's date |
| DescriptionField | A posting or register or entry report item's description |
| TotalField | A balance or posting report item's balance or running total. Always rendered right-justified. |
| DepthSpacerField | A balance report item's indent level (which may be different from the account name depth). Rendered as this number of spaces, multiplied by the minimum width spec if any. |
| FieldNo Int | A report item's nth field. May be unimplemented. |
