Erlang - Atoms. An atom is a literal, a constant with name. An atom is to be enclosed in single quotes (') if it does not begin with a lower-case letter or if it contains other characters than alphanumeric characters, underscore (_), or @. The following program is an example of how atoms can be used in Erlang.

We fix the parser/printer so a '-' in an LFE atom becomes '_' in the Erlang and vice-versa. atoms that are the same also share a single entry in the table. Thus, comparing their entry numbers from this table is sufficient to compare equality between two atoms. In listing 1, an Erlang module, stats, provides an example of a concurrent Erlang program. A process started by stats: Erlang/OTP; ERL-860; erlang:register/2 only accepts atoms as keys erlang:cancel_timer(Ref) cancel_timer(Ref) cancels a timer, where Ref was returned by either send_after/3 or start_timer/3.If the timer was there to be removed, cancel_timer/1 returns the time in ms left until the timer would have expired, otherwise false (which may mean that Ref was never a timer, or that it had already been cancelled, or that it had already delivered its message).

Atoms are a key structure in Erlang. Technically they're just another type of data, but it's hard to overstate their impact on Erlang programming style.

Erlang supports both integer and float values. Atom: start() -> io:fwrite(true) Atoms should start with lower case leters and can contain lowercase and uppercase characters, numbers, _ and @. You can also put atom in single quotes: Boolean: start() -> io:fwrite(10 =< 8) Output will be either true or false based on the values given: Bit String

Say from the Erlang you get ` atoms_rule`, which in LFE becomes `atoms-rule`, nice and lispy. And in LFE `atoms-rule` would translate back to `atoms_rule`.

The following program is an example of how atoms can be used in Erlang. An atom is an object with a name that is identified only by the name itself. Atoms are defined in Erlang using atom literals which are either an unquoted string that starts with a lowercase letter and contains only letters, digits, underscores or the @ character, or A single quoted string 2021-04-13 · There is no Boolean data type in Erlang. Instead the atoms true and false are used to denote Boolean values.
