- gomoddirectives # manages the use of 'replace', 'retract', and 'excludes' directives in go.mod

## you may want to enable
#- decorder # checks declaration order and count of types, constants, variables and functions
# - dupl # tool for code clone detection
#- exhaustruct # [highly recommend to enable] checks if all structure fields are initialized
#- gci # controls golang package import order and makes it always deterministic
#- ginkgolinter # [if you use ginkgo/gomega] enforces standards of using ginkgo and gomega
#- gochecknoglobals # checks that no global variables exist
#- gochecknoinits # checks that no init functions are present in Go code
#- goheader # checks is file header matches to pattern
#- gomnd # detects magic numbers
#- goconst # finds repeated strings that could be replaced by a constant
#- interfacebloat # checks the number of methods inside an interface
#- ireturn # accept interfaces, return concrete types
#- testableexamples # checks if examples are testable (have an expected output)
#- testpackage # makes you use a separate _test package
#- tparallel # detects inappropriate usage of t.Parallel() method in your Go test codes
#- prealloc # [premature optimization, but can be used in some cases] finds slice declarations that could potentially be preallocated
#- varnamelen # [great idea, but too many false positives] checks that the length of a variable's name matches its scope
#- wrapcheck # checks that errors returned from external packages are wrapped
## disabled
#- containedctx # detects struct contained context.Context field
#- contextcheck # [too many false positives] checks the function whether use a non-inherited context
#- depguard # [replaced by gomodguard] checks if package imports are in a list of acceptable packages
#- dogsled # checks assignments with too many blank identifiers (e.g. x, _, _, _, := f())
#- dupword # [useless without config] checks for duplicate words in the source code
#- errchkjson # [don't see profit + I'm against of omitting errors like in the first example https://github.com/breml/errchkjson] checks types passed to the json encoding functions. Reports unsupported types and optionally reports occasions, where the check for the returned error can be omitted
#- forcetypeassert # [replaced by errcheck] finds forced type assertions
#- goerr113 # [too strict] checks the errors handling expressions

## deprecated
#- deadcode # [deprecated, replaced by unused] finds unused code
#- exhaustivestruct # [deprecated, replaced by exhaustruct] checks if all struct's fields are initialized

#- ifshort # [deprecated] checks that your code uses short syntax for if-statements whenever possible
#- interfacer # [deprecated] suggests narrower interface types
#- maligned # [deprecated, replaced by govet fieldalignment] detects Go structs that would take less memory if their fields were sorted
