我设置被叫Inno JSON Config
新的项目,它允许你用简单的JSON配置文件的工作就像如下图所示,它允许您读取和写入字符串,整数和布尔值:
{
"Section_1":{
"Key_1": "String 1",
"Key_2": "1",
"Key_3": "True"
},
"Section_2":{
"Key_1": "String 2",
"Key_2": "2",
"Key_3": "False"
}
}
的用法很简单(甚至当我要添加句柄支持时)。请注意,只有Unicode的Inno Setup的(在最近的版本之一由于需要Int64
支持)可用于:

begin
{ set the source JSON config file path }
FileName := 'c:\Example.json';
{ allocate string buffer to enough length }
SetLength(StrValue, 16);
{ set the buffer length value }
StrLength := Length(StrValue);
{ query string value }
if JSONQueryString(FileName, 'Section_1', 'Key_1', 'Default', StrValue,
StrLength)
then
MsgBox('Section_1:Key_1=' + StrValue, mbInformation, MB_OK);
{ query integer value }
if JSONQueryInteger(FileName, 'Section_1', 'Key_2', 0, IntValue) then
MsgBox('Section_1:Key_2=' + IntToStr(IntValue), mbInformation, MB_OK);
{ query boolean value }
if JSONQueryBoolean(FileName, 'Section_1', 'Key_3', True, BoolValue) then
MsgBox('Section_1:Key_3=' + BoolToStr(BoolValue), mbInformation, MB_OK);
{ write string }
if not JSONWriteString(FileName, 'Section_1', 'Key_1', 'New value!') then
MsgBox('JSONWriteString Section_1:Key_1 failed!', mbError, MB_OK);
{ write integer }
if not JSONWriteInteger(FileName, 'Section_1', 'Key_2', 123) then
MsgBox('JSONWriteInteger Section_1:Key_2 failed!', mbError, MB_OK);
{ write boolean }
if not JSONWriteBoolean(FileName, 'Section_1', 'Key_3', False) then
MsgBox('JSONWriteBoolean Section_1:Key_3 failed!', mbError, MB_OK);
end;
的Inno没有任何原生JSON支持,但你可以分析和修改它一个正常的字符串,然后再写出来。如果一个正则表达式模块对你来说是最简单的方法,那就这样吧。 – Deanna 2013-03-11 17:08:40
如果您只想搜索并替换已知的唯一标记,那么使用“StringChange”或“StringChangeEx”函数。除非你不能使搜索文本唯一,否则不需要正则表达式。 – Miral 2013-03-12 08:12:50
