Uncomment multiline block with NERDCommenter

Question

Is it possible using NERD-commenter to uncomment a multiline block under the cursor without selecting the entire block visually first?

If no, are there any better plugins, that can do the job?

Here is an example:

<dependencies>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.4.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpcore</artifactId>
        <version>4.4.1</version>
    </dependency>
</dependencies>

Commenting out first dependency tag using leadercm I get

<dependencies>
    <!--<dependency>
        <groupId>org.jboss.logmanager</groupId>
    |   <artifactId>log4j-jboss-logmanager</artifactId>
        <version>1.1.1.Final-redhat-1</version>
        <scope>provided</scope>
    </dependency>-->
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpcore</artifactId>
        <version>4.4.1</version>
    </dependency>
</dependencies>

Now I place the cursor inside the commented out tag (like showed above) and want to uncomment the tag.

• leadercu - does nothing
• leadercspace - comments out the current line breaking XML format.

So the problem here is to easily select the commented text. Vim doesn't have a built-in way to select a portion of commented text.

A possible solution is to create a new text object which will represent a chunck of commented code. To do so you can:

• Define it manually which can be a pretty laborious work if you're not used to vimscript (even if you are actually)
• Or you can use the plugin vim-textobj-user which allows the user to easily create new text objects. With the plugin you can install the vim-textobj-comment plugin which uses vim-textobj-user to create the text object we need.

Once it is installed you can simply use vaC to select the commented text and then use the NERDCommenter command leadercu to uncomment your text.
