示例
- 修改
processing
let mut dwsyn = dwparser::parse("{DataWindow Syntax}").unwrap();
dwsyn.modify("DataWindow.Processing = 2");
- 修改字段类型
let mut dwsyn = dwparser::parse("{DataWindow Syntax}").unwrap();
//通过字段名
dwsyn.modify("DataWindow.Table.Column.ColA.ColType = char(255)");
//通过ID
dwsyn.modify("DataWindow.Table.Column.1.ColType = char(255)");
- 删除字段
let mut dwsyn = dwparser::parse("{DataWindow Syntax}").unwrap();
//通过字段名
dwsyn.modify("Destroy DataWindow.Table.Column.ColA");
//通过ID
dwsyn.modify("Destroy DataWindow.Table.Column.1");
- 删除分组
let mut dwsyn = dwparser::parse("{DataWindow Syntax}").unwrap();
dwsyn.modify("Destroy DataWindow.Footer.1");
