bit like [Foreman](https://github.com/ddollar/foreman) but things are designed to run in the background (as well as the foreground if you prefer) and there's a supervisor which keeps an eye on your processes and will respawn them if they die.\n\nProcodile works out of the box with your existing `Procfile`.\n\n* [Watch a quick screencast](https://vimeo.com/188041935)\n* [Read

`String` represents an immutable sequence of UTF-8 characters.\n\nA `String` is typically created with a string literal, enclosing UTF-8 characters\nin double quotes:\n\n```\n\"hello world\"\n```\n\nSee [`String` literals](https://crystal-lang.org/reference/syntax_and_semantics/literals/string.html) in the language reference.\n\nA backslash can be used to denote some characters inside the string:\n\n```\n\"\\\"\" # double quote\n\"\\\\\" # backslash\n\"\\e\" # escape\n\"\\f\" # form feed\n\"\\n\" # newline\n\"\\r\" # carriage return\n\"\\t\" # tab\n\"\\v\" # vertical tab\n```\n\nYou can use a backslash followed by an *u* and four hexadecimal characters to denote a unicode codepoint written:\n\n```\n\"\\u0041\" # == \"A\"\n```\n\nOr you can use curly braces and specify up to six hexadecimal numbers (0 to 10FFFF):\n\n```\n\"\\u{41}\" # == \"A\"\n```\n\nA string can span multiple lines:\n\n```\n\"hello\n world\" # same as \"hello\\n world\"\n```\n\nNote that in the above example trailing and leading spaces, as well as newlines,\nend up in the resulting string. To avoid this, you can split a string into multiple lines\nby joining multiple literals with a backslash:\n\n```\n\"hello \" \\\n\"world, \" \\\n\"no newlines\" # same as \"hello world, no newlines\"\n```\n\nAlternatively, a backslash followed by a newline can be inserted inside the string literal:\n\n```\n\"hello \\\n world, \\\n no newlines\" # same as \"hello world, no newlines\"\n```\n\nIn this case, leading whitespace is not included in the resulting string.\n\nIf you need to write a string that has many double quotes, parentheses, or similar\ncharacters, you can use alternative literals:\n\n```\n# Supports double quotes and nested parentheses\n%(hello (\"world\")) # same as \"hello (\\\"world\\\")\"\n\n# Supports double quotes and nested brackets\n%[hello [\"world\"]] # same as \"hello [\\\"world\\\"]\"\n\n# Supports double quotes and nested curlies\n%{hello {\"world\"}} # same as \"hello {\\\"world\\\"}\"\n\n# Supports double quotes and nested angles\n%> # same as \"hello <\\\"world\\\">\"\n```\n\nTo create a `String` with embedded expressions, you can use string interpolation:\n\n```\na = 1\nb = 2\n\"sum = #{a + b}\" # \"sum = 3\"\n```\n\nThis ends up invoking `Object#to_s(IO)` on each expression enclosed by `#{...}`.\n\nIf you need to dynamically build a string, use `String#build` or `IO::Memory`.\n\n### Non UTF-8 valid strings\n\nString might end up being conformed of bytes which are an invalid\nbyte sequence according to UTF-8. This can happen if the string is created\nvia one of the constructors that accept bytes, or when getting a string\nfrom `String.build` or `IO::Memory`. No exception will be raised, but\ninvalid byte sequences, when asked as chars, will use the unicode replacement\nchar (value 0xFFFD). For example:\n\n```\n# here 255 is not a valid byte value in the UTF-8 encoding\nstring = String.new(Bytes[255, 97])\nstring.valid_encoding? # => false\n\n# The first char here is the unicode replacement char\nstring.chars # => ['�', 'a']\n```\n\nOne can also create strings with specific byte value in them by\nusing octal and hexadecimal escape sequences:\n\n```\n# Octal escape sequences\n\"\\101\" # # => \"A\"\n\"\\12\" # # => \"\\n\"\n\"\\1\" # string with one character with code point 1\n\"\\377\" # string with one byte with value 255\n\n# Hexadecimal escape sequences\n\"\\x41\" # # => \"A\"\n\"\\xFF\" # string with one byte with value 255\n```\n\nThe reason for allowing strings that don't have a valid UTF-8 sequence\nis that the world is full of content that isn't properly encoded,\nand having a program raise an exception or stop because of this\nis not good. It's better if programs are more resilient, but\nshow a replacement character when there's an error in incoming data.","summary":"

`String` represents an immutable sequence of UTF-8 characters.\n\nA `String` is typically created with a string literal, enclosing UTF-8 characters\nin double quotes:\n\n```\n\"hello world\"\n```\n\nSee [`String` literals](https://crystal-lang.org/reference/syntax_and_semantics/literals/string.html) in the language reference.\n\nA backslash can be used to denote some characters inside the string:\n\n```\n\"\\\"\" # double quote\n\"\\\\\" # backslash\n\"\\e\" # escape\n\"\\f\" # form feed\n\"\\n\" # newline\n\"\\r\" # carriage return\n\"\\t\" # tab\n\"\\v\" # vertical tab\n```\n\nYou can use a backslash followed by an *u* and four hexadecimal characters to denote a unicode codepoint written:\n\n```\n\"\\u0041\" # == \"A\"\n```\n\nOr you can use curly braces and specify up to six hexadecimal numbers (0 to 10FFFF):\n\n```\n\"\\u{41}\" # == \"A\"\n```\n\nA string can span multiple lines:\n\n```\n\"hello\n world\" # same as \"hello\\n world\"\n```\n\nNote that in the above example trailing and leading spaces, as well as newlines,\nend up in the resulting string. To avoid this, you can split a string into multiple lines\nby joining multiple literals with a backslash:\n\n```\n\"hello \" \\\n\"world, \" \\\n\"no newlines\" # same as \"hello world, no newlines\"\n```\n\nAlternatively, a backslash followed by a newline can be inserted inside the string literal:\n\n```\n\"hello \\\n world, \\\n no newlines\" # same as \"hello world, no newlines\"\n```\n\nIn this case, leading whitespace is not included in the resulting string.\n\nIf you need to write a string that has many double quotes, parentheses, or similar\ncharacters, you can use alternative literals:\n\n```\n# Supports double quotes and nested parentheses\n%(hello (\"world\")) # same as \"hello (\\\"world\\\")\"\n\n# Supports double quotes and nested brackets\n%[hello [\"world\"]] # same as \"hello [\\\"world\\\"]\"\n\n# Supports double quotes and nested curlies\n%{hello {\"world\"}} # same as \"hello {\\\"world\\\"}\"\n\n# Supports double quotes and nested angles\n%> # same as \"hello <\\\"world\\\">\"\n```\n\nTo create a `String` with embedded expressions, you can use string interpolation:\n\n```\na = 1\nb = 2\n\"sum = #{a + b}\" # \"sum = 3\"\n```\n\nThis ends up invoking `Object#to_s(IO)` on each expression enclosed by `#{...}`.\n\nIf you need to dynamically build a string, use `String#build` or `IO::Memory`.\n\n### Non UTF-8 valid strings\n\nString might end up being conformed of bytes which are an invalid\nbyte sequence according to UTF-8. This can happen if the string is created\nvia one of the constructors that accept bytes, or when getting a string\nfrom `String.build` or `IO::Memory`. No exception will be raised, but\ninvalid byte sequences, when asked as chars, will use the unicode replacement\nchar (value 0xFFFD). For example:\n\n```\n# here 255 is not a valid byte value in the UTF-8 encoding\nstring = String.new(Bytes[255, 97])\nstring.valid_encoding? # => false\n\n# The first char here is the unicode replacement char\nstring.chars # => ['�', 'a']\n```\n\nOne can also create strings with specific byte value in them by\nusing octal and hexadecimal escape sequences:\n\n```\n# Octal escape sequences\n\"\\101\" # # => \"A\"\n\"\\12\" # # => \"\\n\"\n\"\\1\" # string with one character with code point 1\n\"\\377\" # string with one byte with value 255\n\n# Hexadecimal escape sequences\n\"\\x41\" # # => \"A\"\n\"\\xFF\" # string with one byte with value 255\n```\n\nThe reason for allowing strings that don't have a valid UTF-8 sequence\nis that the world is full of content that isn't properly encoded,\nand having a program raise an exception or stop because of this\nis not good. It's better if programs are more resilient, but\nshow a replacement character when there's an error in incoming data.","summary":"

`String` represents an immutable sequence of UTF-8 characters.\n\nA `String` is typically created with a string literal, enclosing UTF-8 characters\nin double quotes:\n\n```\n\"hello world\"\n```\n\nSee [`String` literals](https://crystal-lang.org/reference/syntax_and_semantics/literals/string.html) in the language reference.\n\nA backslash can be used to denote some characters inside the string:\n\n```\n\"\\\"\" # double quote\n\"\\\\\" # backslash\n\"\\e\" # escape\n\"\\f\" # form feed\n\"\\n\" # newline\n\"\\r\" # carriage return\n\"\\t\" # tab\n\"\\v\" # vertical tab\n```\n\nYou can use a backslash followed by an *u* and four hexadecimal characters to denote a unicode codepoint written:\n\n```\n\"\\u0041\" # == \"A\"\n```\n\nOr you can use curly braces and specify up to six hexadecimal numbers (0 to 10FFFF):\n\n```\n\"\\u{41}\" # == \"A\"\n```\n\nA string can span multiple lines:\n\n```\n\"hello\n world\" # same as \"hello\\n world\"\n```\n\nNote that in the above example trailing and leading spaces, as well as newlines,\nend up in the resulting string. To avoid this, you can split a string into multiple lines\nby joining multiple literals with a backslash:\n\n```\n\"hello \" \\\n\"world, \" \\\n\"no newlines\" # same as \"hello world, no newlines\"\n```\n\nAlternatively, a backslash followed by a newline can be inserted inside the string literal:\n\n```\n\"hello \\\n world, \\\n no newlines\" # same as \"hello world, no newlines\"\n```\n\nIn this case, leading whitespace is not included in the resulting string.\n\nIf you need to write a string that has many double quotes, parentheses, or similar\ncharacters, you can use alternative literals:\n\n```\n# Supports double quotes and nested parentheses\n%(hello (\"world\")) # same as \"hello (\\\"world\\\")\"\n\n# Supports double quotes and nested brackets\n%[hello [\"world\"]] # same as \"hello [\\\"world\\\"]\"\n\n# Supports double quotes and nested curlies\n%{hello {\"world\"}} # same as \"hello {\\\"world\\\"}\"\n\n# Supports double quotes and nested angles\n%> # same as \"hello <\\\"world\\\">\"\n```\n\nTo create a `String` with embedded expressions, you can use string interpolation:\n\n```\na = 1\nb = 2\n\"sum = #{a + b}\" # \"sum = 3\"\n```\n\nThis ends up invoking `Object#to_s(IO)` on each expression enclosed by `#{...}`.\n\nIf you need to dynamically build a string, use `String#build` or `IO::Memory`.\n\n### Non UTF-8 valid strings\n\nString might end up being conformed of bytes which are an invalid\nbyte sequence according to UTF-8. This can happen if the string is created\nvia one of the constructors that accept bytes, or when getting a string\nfrom `String.build` or `IO::Memory`. No exception will be raised, but\ninvalid byte sequences, when asked as chars, will use the unicode replacement\nchar (value 0xFFFD). For example:\n\n```\n# here 255 is not a valid byte value in the UTF-8 encoding\nstring = String.new(Bytes[255, 97])\nstring.valid_encoding? # => false\n\n# The first char here is the unicode replacement char\nstring.chars # => ['�', 'a']\n```\n\nOne can also create strings with specific byte value in them by\nusing octal and hexadecimal escape sequences:\n\n```\n# Octal escape sequences\n\"\\101\" # # => \"A\"\n\"\\12\" # # => \"\\n\"\n\"\\1\" # string with one character with code point 1\n\"\\377\" # string with one byte with value 255\n\n# Hexadecimal escape sequences\n\"\\x41\" # # => \"A\"\n\"\\xFF\" # string with one byte with value 255\n```\n\nThe reason for allowing strings that don't have a valid UTF-8 sequence\nis that the world is full of content that isn't properly encoded,\nand having a program raise an exception or stop because of this\nis not good. It's better if programs are more resilient, but\nshow a replacement character when there's an error in incoming data.","summary":"

`String` represents an immutable sequence of UTF-8 characters.\n\nA `String` is typically created with a string literal, enclosing UTF-8 characters\nin double quotes:\n\n```\n\"hello world\"\n```\n\nSee [`String` literals](https://crystal-lang.org/reference/syntax_and_semantics/literals/string.html) in the language reference.\n\nA backslash can be used to denote some characters inside the string:\n\n```\n\"\\\"\" # double quote\n\"\\\\\" # backslash\n\"\\e\" # escape\n\"\\f\" # form feed\n\"\\n\" # newline\n\"\\r\" # carriage return\n\"\\t\" # tab\n\"\\v\" # vertical tab\n```\n\nYou can use a backslash followed by an *u* and four hexadecimal characters to denote a unicode codepoint written:\n\n```\n\"\\u0041\" # == \"A\"\n```\n\nOr you can use curly braces and specify up to six hexadecimal numbers (0 to 10FFFF):\n\n```\n\"\\u{41}\" # == \"A\"\n```\n\nA string can span multiple lines:\n\n```\n\"hello\n world\" # same as \"hello\\n world\"\n```\n\nNote that in the above example trailing and leading spaces, as well as newlines,\nend up in the resulting string. To avoid this, you can split a string into multiple lines\nby joining multiple literals with a backslash:\n\n```\n\"hello \" \\\n\"world, \" \\\n\"no newlines\" # same as \"hello world, no newlines\"\n```\n\nAlternatively, a backslash followed by a newline can be inserted inside the string literal:\n\n```\n\"hello \\\n world, \\\n no newlines\" # same as \"hello world, no newlines\"\n```\n\nIn this case, leading whitespace is not included in the resulting string.\n\nIf you need to write a string that has many double quotes, parentheses, or similar\ncharacters, you can use alternative literals:\n\n```\n# Supports double quotes and nested parentheses\n%(hello (\"world\")) # same as \"hello (\\\"world\\\")\"\n\n# Supports double quotes and nested brackets\n%[hello [\"world\"]] # same as \"hello [\\\"world\\\"]\"\n\n# Supports double quotes and nested curlies\n%{hello {\"world\"}} # same as \"hello {\\\"world\\\"}\"\n\n# Supports double quotes and nested angles\n%> # same as \"hello <\\\"world\\\">\"\n```\n\nTo create a `String` with embedded expressions, you can use string interpolation:\n\n```\na = 1\nb = 2\n\"sum = #{a + b}\" # \"sum = 3\"\n```\n\nThis ends up invoking `Object#to_s(IO)` on each expression enclosed by `#{...}`.\n\nIf you need to dynamically build a string, use `String#build` or `IO::Memory`.\n\n### Non UTF-8 valid strings\n\nString might end up being conformed of bytes which are an invalid\nbyte sequence according to UTF-8. This can happen if the string is created\nvia one of the constructors that accept bytes, or when getting a string\nfrom `String.build` or `IO::Memory`. No exception will be raised, but\ninvalid byte sequences, when asked as chars, will use the unicode replacement\nchar (value 0xFFFD). For example:\n\n```\n# here 255 is not a valid byte value in the UTF-8 encoding\nstring = String.new(Bytes[255, 97])\nstring.valid_encoding? # => false\n\n# The first char here is the unicode replacement char\nstring.chars # => ['�', 'a']\n```\n\nOne can also create strings with specific byte value in them by\nusing octal and hexadecimal escape sequences:\n\n```\n# Octal escape sequences\n\"\\101\" # # => \"A\"\n\"\\12\" # # => \"\\n\"\n\"\\1\" # string with one character with code point 1\n\"\\377\" # string with one byte with value 255\n\n# Hexadecimal escape sequences\n\"\\x41\" # # => \"A\"\n\"\\xFF\" # string with one byte with value 255\n```\n\nThe reason for allowing strings that don't have a valid UTF-8 sequence\nis that the world is full of content that isn't properly encoded,\nand having a program raise an exception or stop because of this\nis not good. It's better if programs are more resilient, but\nshow a replacement character when there's an error in incoming data.","summary":"
