def Lean.Linter.LinterSets : Type

Linter sets are represented as a map from linter name to set name, to make it easy to look up which sets to check for enabling a linter.

Equations

• Lean.Linter.LinterSets = Lean.NameMap (Array Lean.Name)

instance Lean.Linter.instLinterSetsEmptyCollection : EmptyCollection LinterSets

Equations

• Lean.Linter.instLinterSetsEmptyCollection = Lean.NameMap.instEmptyCollection (Array Lean.Name)

instance Lean.Linter.instLinterSetsInhabited : Inhabited LinterSets

Equations

• Lean.Linter.instLinterSetsInhabited = Lean.NameMap.instInhabited (Array Lean.Name)

def Lean.Linter.insertLinterSetEntry (map : LinterSets) (setName : Name) (options : NameSet) : LinterSets

Insert a set into a LinterSets map.

entry.1 is the name of the linter set, entry.2 contains the names of the set's linter options.

opaque Lean.Linter.linterSetsExt : SimplePersistentEnvExtension (Name × NameSet) LinterSets

structure Lean.Linter.LinterOptions : Type

The LinterOptions structure is used to determine whether given linters are enabled.

This structure contains all the data required to do so, the Options set on the command line or by the set_option command, and the LinterSets that have been declared.

A single structure holding this data is useful since we want getLinterValue to be a pure function: determinining the LinterSets would otherwise require a MonadEnv instance.

• toOptions : Options
• linterSets : LinterSets

def Lean.Linter.LinterOptions.get {α : Type} [KVMap.Value α] (o : LinterOptions) (k : Name) (defVal : α) : α

Equations

• o.get = Lean.KVMap.get o.toOptions

def Lean.Linter.LinterOptions.get? {α : Type} [KVMap.Value α] (o : LinterOptions) (k : Name) : Option α

Equations

• o.get? = Lean.KVMap.get? o.toOptions

def Lean.Options.toLinterOptions {m : Type → Type} [Monad m] [MonadEnv m] (o : Options) : m Linter.LinterOptions

Equations

• o.toLinterOptions = do let __do_lift ← Lean.getEnv let linterSets : Lean.Linter.LinterSets := Lean.Linter.linterSetsExt.getState __do_lift pure { toOptions := o, linterSets := linterSets }

def Lean.Linter.LinterOptions.getSet {α : Type} (o : LinterOptions) (opt : Lean.Option α) : Array Name

Return the set of linter sets that this option is contained in.

Equations

• o.getSet opt = Lean.RBMap.findD o.linterSets opt.name #[]

def Lean.Linter.getLinterOptions {m : Type → Type} [Monad m] [MonadOptions m] [MonadEnv m] : m LinterOptions

Equations

• Lean.Linter.getLinterOptions = do let __do_lift ← Lean.getOptions __do_lift.toLinterOptions

opaque Lean.Linter.linter.all : Lean.Option Bool

def Lean.Linter.getLinterAll (o : LinterOptions) (defValue : Bool := linter.all.defValue) : Bool

Equations

• Lean.Linter.getLinterAll o defValue = o.get Lean.Linter.linter.all.name defValue

def Lean.Linter.getLinterValue (opt : Lean.Option Bool) (o : LinterOptions) : Bool

Equations

• Lean.Linter.getLinterValue opt o = o.get opt.name (Lean.Linter.getLinterAll o (((o.getSet opt).any fun (x : Lean.Name) => o.get? x == some true) || opt.defValue))

def Lean.Linter.logLint {m : Type → Type} [Monad m] [MonadLog m] [AddMessageContext m] [MonadOptions m] (linterOption : Lean.Option Bool) (stx : Syntax) (msg : MessageData) : m Unit

def Lean.Linter.logLintIf {m : Type → Type} [Monad m] [MonadLog m] [AddMessageContext m] [MonadOptions m] [MonadEnv m] (linterOption : Lean.Option Bool) (stx : Syntax) (msg : MessageData) : m Unit

If linterOption is enabled, print a linter warning message at the position determined by stx.

Whether a linter option is enabled or not is determined by the following sequence:

1. If it is set, then the value determines whether or not it is enabled.
2. Otherwise, if linter.all is set, then its value determines whether or not the option is enabled.
3. Otherwise, if any of the linter sets containing the option is enabled, it is enabled. (Only enabled linter sets are considered: explicitly disabling a linter set will revert the linters it contains to their default behavior.)
4. Otherwise, the default value determines whether or not it is enabled.
