      Inline Operations

      The manuals explain how to use the different types of inline operations in Pen'script.

      Pen'script now supports inline operations within curly brackets {}. This guide provides a detailed explanation of the new features, including usage examples.

      This manual will discuss the following operators: 

      Pipe Operator

      The pipe operator | allows chaining multiple methods together. The syntax is:

      This is equivalent to:

      Examples:

      Supported Methods:

      • lowercase
      • uppercase
      • capitalize
      • number

      Note: The pipe operator cannot be used with methods that require additional parameters.

      Ternary Operator

      The ternary operator allows inline conditional logic. The syntax is:


      If condition is true, is_true is returned; otherwise, else is returned. If : and else are omitted, the default value is an empty string ''.

      Examples:

      Concatenation

      Use the + operator to concatenate strings or add numbers. If both operands are numbers, addition is performed; if one or both are strings, concatenation is performed.

      Examples:

      Subtraction

      Use the - operator to subtract numbers. Subtraction is only allowed when both operands are numbers. If one or both are strings, the result is undefined.

      Examples:

      Multiplication and division

      Use the * operator to multiply numbers and the / operator to divide numbers.

      Examples:

      Comparisons

      Comparisons can be done using >, ≥, <, ≤, ==, or !=.

      Operator Priorities

      Operators have the following priority order: ? > | > + > -

      Parentheses

      Use parentheses to change the order of operations.

      Test Cases Examples

      Here are some test cases to help you understand how these operations work:

      Test Case
      Expected Output
      {season}
      summer
      { season summer }
      undefined
      {season} cold {season}
      summer cold summer
      {'winter'}
      winter
      {season|uppercase}
      SUMMER
      {season|uppercase} hello
      SUMMER hihi summer WINTER
      {'winter'|uppercase}
      WINTER
      {'season is summer'|uppercase|lowercase}
      season is summer
      {'season is summer'|uppercase|lowercase|capitalize}
      Season Is Summer
      {'season IS SummER'|uppercase|lowercase|uppercase}
      SEASON IS SUMMER
      {'Spring'|uppercase}
      SPRING
      {'spring | uppercase'}
      spring | uppercase
      {"spring | uppercase"}
      spring | uppercase
      {test_function}
      testing | uppercase
      {test_function|uppercase}
      TESTING | UPPERCASE
      {number_str|number}
      172
      {number|number}
      27
      {'string'|number}
      NaN
      { user.birth_date ? 1 : ‘oops’}
      oops
      { user.birth_date ? 1}
       
       
      { true ? true ? 1 : 2 : 3 }
      1
      { true ? false ? 1 : 2 : 3 }
      2
      { false ? false ? 1 : 2 : 3 }
      3
      {'123' + '2132'}
      1232132
      {'? | 123 + 3232 | ? 2 2132'}
      ? | 123 + 3232 | ? 2 2132
      { 14 + 16 }
      30
      { number + 28 }
      55
      { number - 28 }
      -1
      { 2 + 'hello' + 2 }
      2hello2
      { 'hello' - 2 }
       
       
      {'john ' + 'doe'|uppercase}
      john DOE
      { user.family_name ? ‘yes’ + 'sure?'|uppercase : 'nope'}
      yesSURE
      { user.birth_date ? ‘oops’ + 'sure'|uppercase : 'nope'}
      nope
      { 100|number + '99'|number }
