If you really DO need to create dynamic atoms for a quick and dirty hack, keep in mind that atoms with a common prefix ie. foo_1, foo_2, foo_3 etc will lead worse performance because of how erlang compares atoms (some Erlang guru correct me if I'm wrong but this used to be There is an Erlang language, called Standard Erlang, and there is an Erlang Runtime, the BEAM.

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.

As I understood it, dots are legal in unquoted atom names. This appears not to be the case in R16A. Is this intentional? Erlang R15B03 (erts-5.9.3.1) [source] [smp:8:8] [async-threads:0] [hipe] [kernel-poll:false] Eshell V5.9.3.1 (abort with ^G) 1> a.b. 'a.b' 2> Erlang R16A (erts-5.10) [source] [smp:8:8] [async-threads:10] [hipe] [kernel-poll

Once an atom has been created, it lives as long as the Erlang node is running. Type conversions in Erlang are implemented with BIFs in erlang module: > erlang : list_to_integer ( "54" ). 54 > erlang : integer_to_list (42). "42" > erlang : atom_to_list (atom). Atoms in Erlang are sensitive to being misspelled, an the compiler doesn't have a way of checking this. Dialyzer can often detect it, but that has a long turnaround time.

Atoms are a string that starts with "lowercase letters," but if you use single quotes, the name of the atom doesn't matter, and a lot of the tricks come out. 2021-04-11 By convention, most Built-In Functions (BIFs) are included in this module. Some of the BIFs are viewed more or less as part of the Erlang programming language and are auto-imported. Thus, it is not necessary to specify the module name. For example, the calls atom_to_list(erlang) and erlang:atom_to_list(erlang) are … Erlang deﬁnes anorder relationshipbetween values ofany type.

Atoms are unique identifiers within entire system. Header file is not required for atom-enum. Erlang record approach seems to be the best option for it compile-time uniqueness guarantees and membership check. Posted by shubin at 6:30 AM. This issue describes how to implement the atoms concept exercise for the Erlang track.

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).
