我在Delphi中使用了很多Live Templates,但他们试图想出一个将GUIDS添加到模板的解决方案。有谁知道怎么做?
在模板下面,我现在使用GUID作为单词,我需要手动替换。
<?xml version="1.0" encoding="utf-8" ?>
<codetemplate xmlns="http://schemas.borland.com/Delphi/2005/codetemplates"
version="1.0.0">
<template name="iacc" surround="false" invoke="manual">
<point name="name">
<text>
IntfAccessors
</text>
<hint>
Accessors name
</hint>
</point>
<description>
accessor declaration

<code language="Delphi" context="methoddecl" delimiter="|"> <![CDATA[I|name|Accessors = interface(IInterface)
GUID <-- here I want a GUID
end;
I|name| = interface(I|name|Accessors)
GUID <-- here I want a GUID
end;
]]>

您可以通过编写自定义脚本引擎来扩展IDE来执行此操作。 (Here是Nick Hodges写的一篇文章,其中有一个类似的例子,其中插入了当前日期。)
我假设你的示例模板中的两个不同接口需要两个不同的IID,所以我编写了脚本引擎来加载“脚本”中的点名称(它只是名称=值对的列表,其中名称是点名称和值必须是NewGuid,否则会被忽略)因此您可以创建具有多个点的模板,每个点都接收一个单独的新IID。
示例模板intf.xml:
<?xml version="1.0" encoding="utf-8" ?>
<codetemplate xmlns="http://schemas.borland.com/Delphi/2005/codetemplates" version="1.0.0">
<template name="iacc" surround="false" invoke="manual">
<point name="name">
<text>
Accessor
</text>
<hint>
Accessors name
</hint>
</point>
<point name="guid1"/>
<point name="guid2"/>
<description>
accessor declaration

<script language="NewGuidScript" onvalidate="true">
guid1=NewGuid
guid2=NewGuid
</script>
<code language="Delphi" context="any" delimiter="|"> <![CDATA[I|name|Accessors = interface(IInterface)
|*||guid1|
end;
I|name| = interface(I|name|Accessors)
|*||guid2|
end;]]>
</code>
</template>
</codetemplate>
NewGuidScriptEngine.pas:
unit NewGuidScriptEngine;
interface
uses
Classes, SysUtils,
ToolsApi, CodeTemplateApi, DesignEditors;
type
TNewGuidScriptEngine = class(TNotifierObject, IOTACodeTemplateScriptEngine)
public
procedure Execute(const ATemplate: IOTACodeTemplate; const APoint: IOTACodeTemplatePoint; const ASyncPoints: IOTASyncEditPoints; const AScript: IOTACodeTemplateScript; var Cancel: Boolean);
function GetIDString: WideString;
function GetLanguage: WideString;
end;
procedure Register;
implementation
uses
ActiveX,
ComObj;
procedure Register;
begin
(BorlandIDEServices as IOTACodeTemplateServices).RegisterScriptEngine(TNewGuidScriptEngine.Create);
end;
procedure TNewGuidScriptEngine.Execute(const ATemplate: IOTACodeTemplate; const APoint: IOTACodeTemplatePoint;
const ASyncPoints: IOTASyncEditPoints; const AScript: IOTACodeTemplateScript; var Cancel: Boolean);
var
I: Integer;
Guid: TGUID;
P: IOTACodeTemplatePoint;
Points: TStringList;
begin
Cancel := False;
if not Assigned(ATemplate) then
Exit;
Points := TStringList.Create;
try
Points.Text := AScript.Script;
for I := 0 to Points.Count - 1 do
Points.Strings[I] := Trim(Points[I]);
for I := 0 to Points.Count - 1 do
if Points.ValueFromIndex[I] = 'NewGuid' then
begin
P := ATemplate.FindPoint(Points.Names[I]);
if Assigned(P) then
begin
OleCheck(CoCreateGuid(Guid));
P.Editable := False;
P.Value := '[''' + GUIDToString(Guid) + ''']';
end;
end;
finally
Points.Free;
end;
end;
function TNewGuidScriptEngine.GetIDString: WideString;
begin
Result := 'OndrejKelle.NewGuidScriptEngine';
end;
function TNewGuidScriptEngine.GetLanguage: WideString;
begin
Result := 'NewGuidScript';
end;
end.
将上述单元放入仅限designtime的软件包中,将designide.dcp的引用添加到其requires
子句中,并在IDE中安装该软件包。
另一个有用的类似模板可能如下所示:
<?xml version="1.0" encoding="utf-8" ?>
<codetemplate xmlns="http://schemas.borland.com/Delphi/2005/codetemplates" version="1.0.0">
<template name="iacc" surround="false" invoke="manual">
<point name="name">
<text>
</text>
<hint>
Accessors name
</hint>
</point>
<point name="guid1"/>
<point name="guid2"/>

<script language="NewGuidScript" onvalidate="true">

guid2=NewGuid
</script>
<code language="Delphi" context="any" delimiter="|"> <![CDATA[const
SIID_I|name|Accessors = |guid1|;
IID_I|name|Accessors: TGUID = SIID_I|name|Accessors;
SIID_I|name| = |guid2|;
IID_I|name|: TGUID = SIID_I|name|;
type
I|name|Accessors = interface
[SIID_I|name|Accessors]
end;
I|name| = interface(I|name|Accessors)
[SIID_I|name|]
end;]]>

</codetemplate>
这将声明字符串以及TGUID
常量,并在接口声明中重用它们。在这种情况下,插入的GUID值不应括在方括号中。您可以通过多种方法调整脚本引擎来执行此操作:
