有没有办法在Eclipse（Helios）代码模板中大写一个变量值的第一个字母 [英] Is there a way to capitalize the first letter of a value of a variable in Eclipse (Helios) code templates

问题描述

我有一个带有变量的代码模板，我想在某些情况下大写（仅第一个字母）该变量的值。有没有办法这样做？

模板代码如下 - 我想在我的函数名中大写Property Name ...

  private $$$ {PropertyName}; 
 $ {cursor} 
 public function get $ {PropertyName}（）
 {
 return $$ this-> $ {PropertyName}; 
} 
 
 public function set $ {PropertyName}（$$ value）
 {
 $$ this-> $ {PropertyName} = $$ value; 
} 
  

请注意：这是与IDE中的代码模板一起使用的模板（不在PHP）。有关详细信息，请参阅： http://www.ibm .com / developerworks / opensource / tutorials / os-eclipse-code-templates / index.html

解决方案

也想要这个，并试图构建一个自定义的 TemplateVariableResolver 来做到这一点。 （我已经有一个自定义解析器生成新的UUID a http： //dev.eclipse.org/blogs/jdtui/2007/12/04/text-templates-2/ 。）

我做了一个自定义解析器绑定到大写：

  public class CapitalizingVariableResolver extends TemplateVariableResolver {
 @Override 
 public void resolve（TemplateVariable variable，TemplateContext context）{
 @SuppressWarnings（unchecked）
 final List< String> params = variable.getVariableType（）。getParams（）; 
 
 if（params.isEmpty（））
 return; 
 
 final String currentValue = context.getVariable（params.get（0））; 
 
 if（currentValue == null || currentValue.length（）== 0）
 return; 
 
 variable.setValue（currentValue.substring（0，1）.toUpperCase（）+ currentValue.substring（1））; 
} 
} 
  

（plugin.xml：）

 < extension point =org.eclipse.ui.editors.templates> 
< resolver 
 class =com.foo.CapitalizingVariableResolver
 contextTypeId =java
 description =解析由第一个参数命名的变量的值，但其第一个字母大写。 
 name =大写
 type =大小写> 
< / resolver> 
< / extension> 
  

我将使用这样：（我在Java工作;我看到你没有出现to be）

  public PropertyAccessor< $ {propertyType}> $ {property：field}（）{
 return $ {property}; 
} 
 
 public $ {propertyType} get $ {capitalizedProperty：capitalize（property）}（）{
 return $ {property} .get（）; 
} 
 
 public void set $ {capitalizedProperty}（$ {propertyType} $ {property}）{
 this。$ {property} .set（$ {property}）; 
} 
  

截至Eclipse 3.5，我遇到的问题是我的自定义解析器一旦指定了属性变量的值，就无法重新解析。看来，Java开发工具（Eclipse JDT）通过一个名为 MultiVariableGuess 的机制，在 JavaContext （见 addDependency（））。不幸的是，我们似乎没有暴露这种机制，所以我/我们不能使用它来做同样的事情（没有大量的复制和粘贴或其他冗余工作）。

在这一点上，我放弃了一段时间，并将继续输入领先的小写和大写字母名称，分成两个独立的模板变量。

I have a code template with a variable and I would like to capitalize(just the first letter) the value of this variable only in some occurrences. Is there a way to do this?

The template code is as follows - I would like to capitalize Property Name in my function names...

private $$${PropertyName};
${cursor}    
public function get${PropertyName}() 
{
  return $$this->${PropertyName};
}

public function set${PropertyName}($$value) 
{
  $$this->${PropertyName} = $$value;
}

Please Note: This is a template for use with code templates in the IDE (not in PHP). For details see: http://www.ibm.com/developerworks/opensource/tutorials/os-eclipse-code-templates/index.html

解决方案

I also want this and tried to build a custom TemplateVariableResolver to do it. (I already have one custom resolver in place that generates new UUIDs a la http://dev.eclipse.org/blogs/jdtui/2007/12/04/text-templates-2/.)

I made a custom resolver bound to capitalize:

public class CapitalizingVariableResolver extends TemplateVariableResolver {
    @Override
    public void resolve(TemplateVariable variable, TemplateContext context) {
        @SuppressWarnings("unchecked")
        final List<String> params = variable.getVariableType().getParams();

        if (params.isEmpty())
            return;

        final String currentValue = context.getVariable(params.get(0));

        if (currentValue == null || currentValue.length() == 0)
            return;

        variable.setValue(currentValue.substring(0, 1).toUpperCase() + currentValue.substring(1));
    }
}

(plugin.xml:)

<extension point="org.eclipse.ui.editors.templates">
  <resolver
        class="com.foo.CapitalizingVariableResolver"
        contextTypeId="java"
        description="Resolves to the value of the variable named by the first argument, but with its first letter capitalized."
        name="capitalized"
        type="capitalize">
  </resolver>
</extension>

that I would use like this: (I am working in Java; I see that you do not appear to be)

public PropertyAccessor<${propertyType}> ${property:field}() {
    return ${property};
}

public ${propertyType} get${capitalizedProperty:capitalize(property)}() {
    return ${property}.get();
}

public void set${capitalizedProperty}(${propertyType} ${property}) {
    this.${property}.set(${property});
}

As of Eclipse 3.5, the problem I am having is that my custom resolver does not get a chance to re-resolve once I've specified a value for the property variable. It appears that the Java Development Tools (Eclipse JDT) do this dependent template variable re-resolution via a mechanism called MultiVariableGuess within the JavaContext (see addDependency()). Unfortunately for us, that mechanism does not seem to be exposed, so I/we can't use it to do the same (without lots of copy-and-paste or other redundant work).

At this point, I am giving up again for a while and will keep typing the leading-lowercase and leading-uppercase names separately into two independent template variables.
