It seems you can’t do it “directly” Try use helper, why not? Register helper in your javascript code: Handlebars.registerHelper(‘ifEquals’, function(arg1, arg2, options) { return (arg1 == arg2) ? options.fn(this) : options.inverse(this); }); Use in template: {{#ifEquals sampleString “This is a string”}} Your HTML here {{/ifEquals}} More details here: Logical operator in a handlebars.js {{#if}} conditional … Read more
To find out if a string contains substring you can use the index function: if (index($str, $substr) != -1) { print “$str contains $substr\n”; } It will return the position of the first occurrence of $substr in $str, or -1 if the substring is not found.
You can use the Time.String() method to convert a time.Time to a string. This uses the format string “2006-01-02 15:04:05.999999999 -0700 MST”. If you need other custom format, you can use Time.Format(). For example to get the timestamp in the format of yyyy-MM-dd HH:mm:ss use the format string “2006-01-02 15:04:05”. Example: t := time.Now() fmt.Println(t.String()) … Read more
Use ioutil.ReadFile: func ReadFile(filename string) ([]byte, error) ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported. You will get a []byte instead … Read more
Update for Swift 2.1: You can create a String from an array of UTF-16 characters with the public init(utf16CodeUnits: UnsafePointer<unichar>, count: Int) initializer. Example: let str = “H€llo 😄” // String to UTF16 array: let utf16array = Array(str.utf16) print(utf16array) // Output: [72, 8364, 108, 108, 111, 32, 55357, 56836] // UTF16 array to string: let … Read more
If you use @fedorqui’s resource, you’ll see it is going to strip the shortest match of /* from the end of the first positional argument. An example: example_foo(){ echo ${1%/*} } example_foo path/to/directory/sub_directory # => path/to/directory In the example I used the second positional argument since the first is the name of the function.
The default shell (/bin/sh) under Ubuntu points to dash, not bash. [email protected]:~$ readlink -f $(which sh) /bin/dash So if you chmod +x your_script_file.sh and then run it with ./your_script_file.sh, or if you run it with bash your_script_file.sh, it should work fine. Running it with sh your_script_file.sh will not work because the hashbang line will be … Read more

It returns the pointer to the storage used for the object referenced by object. addressOf() cannot be used with struct variables: struct Foo { } var f = Foo() let a = unsafeAddressOf(f) // error: cannot invoke ‘unsafeAddressOf’ with an … Read more
