# SSF
SpreadSheet Format (SSF) is a pure-JS library to format data using ECMA-376
spreadsheet format codes (like those used in Microsoft Excel)
ssf (SpreadSheet Format) is a pure-JS library to format data using ECMA-376
spreadsheet format codes (used in popular spreadsheet software packages).
This is written in [voc](https://npmjs.org/package/voc) -- see ssf.md for code.
To build: `voc ssf.md`
## Installation
## Setup
With [npm](https://www.npmjs.org/package/ssf):
```bash
$ npm install ssf
```
In the browser:
<script src="ssf.js"></script>
```html
<script src="ssf.js"></script>
```
In node:
The browser exposes a variable `SSF`
var SSF = require('ssf');
When installed globally, npm installs a script `ssf` that renders the format
string with the given arguments. Running the script with `-h` displays help.
The script will manipulate `module.exports` if available (e.g. in a CommonJS
`require` context). This is not always desirable. To prevent the behavior,
define `DO_NOT_EXPORT_SSF`:
The script will manipulate `module.exports` if available (e.g. in a CommonJS
`require` context). This is not always desirable. To prevent the behavior,
define `DO_NOT_EXPORT_SSF`.
## Usage
`.load(fmt, idx)` sets custom formats (generally indices above `164`).
`SSF.format(fmt, val, opts)` formats `val` using the format `fmt`. If `fmt` is
a string, it will be parsed and evaluated. If `fmt` is a `number`, the actual
format will be the corresponding entry in the internal format table.
`.format(fmt, val, opts)` formats `val` using the format `fmt`. If `fmt` is of
type `number`, the internal table (and custom formats) will be used. If `fmt`
is a literal format, then it will be parsed and evaluated.
### Manipulating the Internal Format Table
`.parse_date_code(val, opts)` parses `val` as date code and returns object:
Binary spreadsheet formats store cell formats in a table and reference by index.
This library uses a global table:
- `D,T`: Date (`[val]`) Time (`{val}`)
- `y,m,d`: Year, Month, Day
- `H,M,S,u`: (0-23)Hour, Minute, Second, Sub-second
- `q`: Day of Week (0=Sunday, 1=Monday, ..., 5=Friday, 6=Saturday)
`SSF._table` is the underlying object, mapping numeric keys to format strings.
`.get_table()` gets the internal format table (number to format mapping).
`SSF.load(fmt:string, idx:?number):number` assigns the format to the specified
index and returns the index. If the index is not specified, SSF will search the
space for an available format slot pick an unused slot. For compatibility with
the XLS and XLSB file formats, custom indices should be in the valid ranges
`5-8`, `23-26`, `41-44`, `63-66`, `164-382` (see `[MS-XLSB] 2.4.655 BrtFmt`)
`.load_table(table)` sets the internal format table.
`SSF.get_table()` gets the internal format table (number to format mapping).
## Notes
`SSF.load_table(table)` sets the internal format table.
### Other Utilities
`SSF.parse_date_code(val:number, opts:?any)` parses `val`, returning an object:
```typescript
type SSFDate = {
D:number; /* number of whole days since relevant epoch, 0 <= D */
y:number; /* integral year portion, epoch_year <= y */
m:number; /* integral month portion, 1 <= m <= 12 */
d:number; /* integral day portion, subject to gregorian YMD constraints */
q:number; /* integral day of week (0=Sunday .. 6=Saturday) 0 <= q <= 6 */
T:number; /* number of seconds since midnight, 0 <= T < 86400 */
H:number; /* integral number of hours since midnight, 0 <= H < 24 */
M:number; /* integral number of minutes since the last hour, 0 <= M < 60 */
S:number; /* integral number of seconds since the last minute, 0 <= S < 60 */
u:number; /* sub-second part of time, 0 <= u < 1 */
}
```
Format code 14 in the spec is broken; the correct format is 'mm/dd/yy' (dashes,
not spaces)
