Elixir string interpolation for the Rubyist (and others)Elixir string interpolation for the Rubyist (and others)Written January 5, 2016. Tagged Elixir. On the surface, Elixir string interpolation looks identical to what we know from Ruby:
Form “objects” in Elixir
Well, let’s begin with explaining the title: Form Object is a common pattern in web development which wraps user input into a convenient structure to be processed in the application. It’s basically an aggregation of an incoming payload, for the program’s convenience, with some basic casting and validation. Why did I put objects in quotes then? Because in Elixir we actually don’t have objects thems
Elixir and Unicode, Part 2: Working with Unicode Strings - Big Nerd Ranch
Elixir and Unicode, Part 2: Working with Unicode Strings This post was adapted from a talk called “String Theory”, which I co-presented with James Edward Gray II at Elixir & Phoenix Conf 2016. In my post on Unicode and UTF-8, I showed you the basis of Elixir’s great Unicode support: every string in Elixir is a series of codepoints, encoded in UTF-8. I explained what Unicode is, and we walked throu
String – Elixir v1.1.1
Elixir v1.1.1 String A String in Elixir is a UTF-8 encoded binary. Codepoints and graphemes The functions in this module act according to the Unicode Standard, version 6.3.0. As per the standard, a codepoint is a Unicode Character, which may be represented by one or more bytes. For example, the character “é” is represented with two bytes: iex> byte_size("é") 2 However, this module returns the prop
Basic types — Elixir v1.18.4
In this chapter we will learn more about Elixir basic types: integers, floats, booleans, atoms, and strings. Other data types, such as lists and tuples, will be explored in the next chapter. iex> 1 # integer iex> 0x1F # integer iex> 1.0 # float iex> true # boolean iex> :atom # atom / symbol iex> "elixir" # string iex> [1, 2, 3] # list iex> {1, 2, 3} # tupleBasic arithmeticOpen up iex and type the
Binaries, strings, and charlists — Elixir v1.18.3
In "Basic types", we learned a bit about strings and we used the is_binary/1 function for checks: iex> string = "hello" "hello" iex> is_binary(string) trueIn this chapter, we will gain clarity on what exactly binaries are and how they relate to strings. We will also learn about charlists, ~c"like this", which are often used for interoperability with Erlang. Although strings are one of the most com
String – Elixir v1.6.5
Elixir v1.6.5 String View Source A String in Elixir is a UTF-8 encoded binary. Codepoints and grapheme cluster The functions in this module act according to the Unicode Standard, version 10.0.0. As per the standard, a codepoint is a single Unicode Character, which may be represented by one or more bytes. For example, the codepoint “é” is two bytes: iex> byte_size("é") 2 However, this module return
