About

The L namespace is reserved for error codes emitted by the Erlang code linter erl_lint.

The erl_lint module is used to check Erlang code for illegal syntax and other bugs. It also warns against coding practices that are not recommended.

The errors detected include:

• Redefined and undefined functions
• Unbound and unsafe variables
• Illegal record use

The warnings detected include:

• Unused functions and imports
• Unused variables
• Variables imported into matches
• Variables exported from if/case/receive
• Variables shadowed in funs and list comprehensions

Some of the warnings are optional, and can be turned on by specifying the appropriate option, described below.
