If you use `fmt` package, you need `%t` format syntax. See package&#39;s [reference](http://golang.org/pkg/fmt/) for details.

Use `%t` to format a boolean as `true` or `false`.

&quot;%t&quot; is the answer for you.

    package main
    import &quot;fmt&quot;
    
    func main() {
       s := true
       fmt.Printf(&quot;%t&quot;, s)
    }

Some other options:

~~~
package main
import &quot;strconv&quot;

func main() {
   s := strconv.FormatBool(true)
   println(s == &quot;true&quot;)
}
~~~

~~~
package main
import &quot;fmt&quot;

func main() {
   var s string
   // example 1
   s = fmt.Sprint(true)
   println(s == &quot;true&quot;)
   // example 2
   s = fmt.Sprintf(&quot;%v&quot;, true)
   println(s == &quot;true&quot;)
}
~~~

I&#39;m looking for a list of all screen aspect ratios for popular Android based Phones and Tablets.

What are the aspect ratios for all Android phone and tablet devices?

I have a plugin (FindFile.vim) that needs to run `:FindFileCache .` whenever I start vim to gather a file cache for quick opening.. I have to run this every time I start vim though. 

How might I write a command that runs once, every time that vim starts up?

As we have `%d` for int. What is the format specifier for boolean values?

How to print boolean value in Go?

<p>As we have <code>%d</code> for int. What is the format specifier for boolean values?</p>


I&#39;ve always coded in the style of `if not value`, however, a few guides have brought to my attention that while this style works, it seems to have 2 potential problems:

1. It&#39;s not completely readable; `if value is None` is surely more understandable.
2. This can have implications later (and cause subtle bugs), since things like `[]` and `0` will evaluate to `False` as well.

I am also starting to apply this idea to other comparisons, such as:

* `if not value` vs `if value is False`
* `if not value` vs `if value is []`

And so goes the list...

The question is, how far do you go with the principle? Where to draw the line, while keeping your code safe?

Should I always use the `if value is None` style no matter what?

How to write literal boolean value in SQL Server? See sample use:

    select * from SomeTable where PSEUDO_TRUE

another sample:

    if PSEUDO_TRUE
    begin
      select &#39;Hello, SQL!&#39;
    end 

Note: The query above has nothing to do with how I&#39;m going to use it. It is just to test the literal boolean.

How can I convert string to `boolean`?

    $string = &#39;false&#39;;
    
    $test_mode_mail = settype($string, &#39;boolean&#39;);
    
    var_dump($test_mode_mail);
    
    if($test_mode_mail) echo &#39;test mode is on.&#39;;

it returns,

&gt; boolean true

but it should be `boolean false`.

How to convert string to boolean php

The following shows that `&quot;0&quot;` is false in Javascript:

    &gt;&gt;&gt; &quot;0&quot; == false
    true
    
    &gt;&gt;&gt; false == &quot;0&quot;
    true

So why does the following print `&quot;ha&quot;`?

    &gt;&gt;&gt; if (&quot;0&quot;) console.log(&quot;ha&quot;)
    ha


In JavaScript, why is &quot;0&quot; equal to false, but when tested by &#39;if&#39; it is not false by itself?

I have a variable that stores `false` or `true`, but I need `0` or `1` instead, respectively. How can I do this?

Convert boolean result into number/integer

So I can read from a local file like so:

    data, error := ioutil.ReadFile(name)

And I can write to a local file

    ioutil.WriteFile(filename, content, permission)

But how can I append to a file? Is there a built in method?

Append to a file in Go

Given

    var dst, src map[K]V

I can copy all entries from `src` into `dst` by doing

    for k, v := range src {
        dst[k] = v
    }

Is there a more idiomatic way to do this?

`copy` only works on slices (and `string` as a source).

Copying all elements of a map into another

I&#39;m currently working my way through the excellent [Tour of Go](https://tour.golang.org/).
I finished one of the exercises (#45) with the following solution:

    func Pic(dx, dy int) [][]uint8 {
    	pic := make([][]uint8, dy) /* type declaration */
    	for i := range pic {
    		pic[i] = make([]uint8, dx) /* again the type? */
    		for j := range pic[i] {
    			pic[i][j] = uint8((i+j)/2)
    		}
    	}
    	return pic
    }

I don&#39;t understand why I have to use a `make` statement with the `uint8` type twice (see comments in snippet). That seems redundant but I can&#39;t figure out how to do it in an other way.

Slice of slices types

Is there a `foreach` construct in the Go language? 
Can I iterate over a slice or array using a `for`?

Is there a foreach loop in Go?

Go is a garbage collected language:

http://golang.org/doc/go_faq.html#garbage_collection

Here it says that it&#39;s a mark-and-sweep garbage collector, but it doesn&#39;t delve into details, and a replacement is in the works... yet, this paragraph seems not to have been updated much since Go was released.

It&#39;s still mark-and-sweep? Is it conservative or precise? Is it generational?
