### Variables and Substitution
### Expressions and Substitutions

Various operators and function calls are supported in expressions, which may be
used in assignments, default recipe arguments, and inside recipe body `{{…}}`

#### Concatenation
The `+` operator returns the left-hand argument concatenated with the
right-hand argument:
```just
foobar := 'foo' + 'bar'
```
#### Logical Operators
The logical operators `&&` and `||` can be used to coalesce string
values<sup>master</sup>, similar to Python's `and` and `or`. These operators
consider the empty string `''` to be false, and all other strings to be true.
These operators are currently unstable.
The `&&` operator returns the empty string if the left-hand argument is the
empty string, otherwise it returns the right-hand argument:
```justfile
foo := '' && 'goodbye' # ''
bar := 'hello' && 'goodbye' # 'goodbye'
```
The `||` operator returns the left-hand argument if it is non-empty, otherwise
it returns the right-hand argument:
```justfile
foo := '' || 'goodbye' # 'goodbye'
bar := 'hello' || 'goodbye' # 'hello'
```

#### Style

escape sequence used by `just`. Unlike terminal display attribute escape
sequence constants, which contain standard colors and styles, `style(name)`
returns an escape sequence used by `just` itself, and can be used to make
recipe output match `just`'s own output.
Recognized values for `name` are `'command'`, for echoed recipe lines,
`error`, and `warning`.

`CLEAR` clears the screen, similar to the `clear` command. The rest are of the
form `\e[Nm`, where `N` is an integer, and set terminal display attributes.
Terminal display attribute escape sequences can be combined, for example text
weight `BOLD`, text style `STRIKETHROUGH`, foreground color `CYAN`, and
background color `BG_BLUE`. They should be followed by `NORMAL`, to reset the
terminal back to normal.
Escape sequences should be quoted, since `[` is treated as a special character
by some shells.

### Printing Complex Strings
`echo` can be used to print strings, but because it processes escape sequences,
like `\n`, and different implementations of `echo` recognize different escape
sequences, using `printf` is often a better choice.
`printf` takes a C-style format string and any number of arguments, which are
interpolated into the format string.
This can be combined with indented, triple quoted strings to emulate shell
heredocs.
Substitution complex strings into recipe bodies with `{…}` can also lead to
trouble as it may be split by the shell into multiple arguments depending on
the presence of whitespace and quotes. Exporting complex strings as environment
variables and referring to them with `"$NAME"`, note the double quotes, can
also help.
Putting all this together, to print a string verbatim to standard output, with
all its various escape sequences and quotes undisturbed:
```just
export FOO := '''
a complicated string with
some dis\tur\bi\ng escape sequences
and "quotes" of 'different' kinds
'''
bar:
printf %s "$FOO"
```
