The second goal of this RFC is to **make +lints independant of the compiler's AST / HIR data structures**. + +# Approach + +A lot of complexity in writing lints currently seems to come from having to +manually implement the matching logic (see code samples above). It's an +imparative style that describes *how* to match a syntax tree node instead of +specifying *what* should be matched against declaratively. In other areas, it's +common to use declarative patterns to describe desired information and let the +implementation do the actual matching. A well-known example of this approach are +[regular expressions](https://en.wikipedia.org/wiki/Regular_expression). Instead +of writing code that detects certain character sequences, one can describe a +search pattern using a domain-specific language and search for matches using +that pattern. The advantage of using a declarative domain-specific language is +that its limited domain (e.g. matching character sequences in the case of +regular expressions) allows to express entities in that domain in a very natural +and expressive way. + +While regular expressions are very useful when searching for patterns in flat +character sequences, they cannot easily be applied to hierarchical data +structures like syntax trees. This RFC therefore proposes a pattern matching +system that is inspired by regular expressions and designed for hierarchical +syntax trees. + +# Guide-level explanation + +This proposal adds a `pattern!` macro that can be used to specify a syntax tree +pattern to search for. A simple pattern is shown below: + +```rust +pattern!{ + my_pattern: Expr = + Lit(Bool(false)) +} +``` + +This macro call defines a pattern named `my_pattern` that can be matched against +an `Expr` syntax tree node. The actual pattern (`Lit(Bool(false))` in this case) +defines which syntax trees should match the pattern. This pattern matches +expressions that are boolean literals with value `false`. + +The pattern can then be used to implement lints in the following way: + +```rust +... + +impl EarlyLintPass for MyAwesomeLint { + fn check_expr(&mut self, cx: &EarlyContext, expr: &syntax::ast::Expr) { + + if my_pattern(expr).is_some() { + cx.span_lint( + MY_AWESOME_LINT, + expr.span, + "This is a match for a simple pattern. Well done!", + ); + } + + } +} +``` + +The `pattern!` macro call expands to a function `my_pattern` that expects a +syntax tree expression as its argument and returns an `Option` that indicates +whether the pattern matched. + +> Note: The result type is explained in more detail in [a later +> section](#the-result-type). For now, it's enough to know that the result is +> `Some` if the pattern matched and `None` otherwise. + +## Pattern syntax + +The following examples demonstate the pattern syntax: + + +#### Any (`_`) + +The simplest pattern is the any pattern. It matches anything and is therefore +similar to regex's `*`. + +```rust +pattern!{ + // matches any expression + my_pattern: Expr = + _ +} +``` + +#### Node (`()`) + +Nodes are used to match a specific variant of an AST node. A node has a name and +a number of arguments that depends on the node type. For example, the `Lit` node +has a single argument that describes the type of the literal. As another +example, the `If` node has three arguments describing the if's condition, then +block and else block. + +```rust +pattern!{ + // matches any expression that is a literal + my_pattern: Expr = + Lit(_) +} + +pattern!{ + // matches any expression that is a boolean literal + my_pattern: Expr = + Lit(Bool(_)) +} + +pattern!{ + // matches if expressions that have a boolean literal in their condition + // Note: The `_?` syntax here means that the else branch is optional and can be anything. + // This is discussed in more detail in the section `Repetition`. + my_pattern: Expr = + If( Lit(Bool(_)) , _, _?) +} +``` + + +#### Literal (``) + +A pattern can also contain Rust literals. These literals match themselves. + +```rust +pattern!{ + // matches the boolean literal false + my_pattern: Expr = + Lit(Bool(false)) +} + +pattern!{ + // matches the character literal 'x' + my_pattern: Expr = + Lit(Char('x')) +} +``` + +#### Alternations (`a | b`) + +```rust +pattern!{ + // matches if the literal is a boolean or integer literal + my_pattern: Lit = + Bool(_) | Int(_) +} + +pattern!{ + // matches if the expression is a char literal with value 'x' or 'y' + my_pattern: Expr = + Lit( Char('x' | 'y') ) +} +``` + +#### Empty (`()`) + +The empty pattern represents an empty sequence or the `None` variant of an +optional. + +```rust +pattern!{ + // matches if the expression is an empty array + my_pattern: Expr = + Array( () ) +} + +pattern!{ + // matches if expressions that don't have an else clause + my_pattern: Expr = + If(_, _, ()) +} +``` + +#### Sequence (` `) + +```rust +pattern!{ + // matches the array [true, false] + my_pattern: Expr = + Array( Lit(Bool(true)) Lit(Bool(false)) ) +} +``` + +#### Repetition (`*`, `+`, `?`, `{n}`, `{n,m}`, `{n,}`) + +Elements may be repeated.

For example, a lint might want to check whether a node was +created as part of a macro expansion or whether there's no comment above a node. +Another example would be a lint that wants to match two nodes that have the same +value (as needed by lints like `almost_swapped`). Instead of allowing users to +write these checks into the pattern directly (which might make patterns hard to +read), the proposed solution allows users to assign names to parts of a pattern +expression. When matching a pattern against a syntax tree node, the return value +will contain references to all nodes that were matched by these named +subpatterns. This is similar to capture groups in regular expressions. + +For example, given the following pattern + +```rust +pattern!{ + // matches character literals + my_pattern: Expr = + Lit(Char(_#val_inner)#val)#val_outer +} +``` + +one could get references to the nodes that matched the subpatterns in the +following way: + +```rust +... +fn check_expr(expr: &syntax::ast::Expr) { + if let Some(result) = my_pattern(expr) { + result.val_inner // type: &char + result.val // type: &syntax::ast::Lit + result.val_outer // type: &syntax::ast::Expr + } +} +``` + +The types in the `result` struct depend on the pattern. For example, the +following pattern + +```rust +pattern!{ + // matches arrays of character literals + my_pattern_seq: Expr = + Array( Lit(_)*#foo ) +} +``` + +matches arrays that consist of any number of literal expressions. Because those +expressions are named `foo`, the result struct contains a `foo` attribute which +is a vector of expressions: + +```rust +... +if let Some(result) = my_pattern_seq(expr) { + result.foo // type: Vec<&syntax::ast::Expr> +} +``` + +Another result type occurs when a name is only defined in one branch of an +alternation: + +```rust +pattern!{ + // matches if expression is a boolean or integer literal + my_pattern_alt: Expr = + Lit( Bool(_#bar) | Int(_) ) +} +``` + +In the pattern above, the `bar` name is only defined if the pattern matches a +boolean literal. If it matches an integer literal, the name isn't set. To +account for this, the result struct's `bar` attribute is an option type: + +```rust +... +if let Some(result) = my_pattern_alt(expr) { + result.bar // type: Option<&bool> +} +``` + +It's also possible to use a name in multiple alternation branches if they have +compatible types: + +```rust +pattern!{ + // matches if expression is a boolean or integer literal + my_pattern_mult: Expr = + Lit(_#baz) | Array( Lit(_#baz) ) +} +... +if let Some(result) = my_pattern_mult(expr) { + result.baz // type: &syntax::ast::Lit +} +``` + +Named submatches are a **flat** namespace and this is intended. In the example +above, two different sub-structures are assigned to a flat name. I expect that +for most lints, a flat namespace is sufficient and easier to work with than a +hierarchical one. + +#### Two stages + +Using named subpatterns, users can write lints in two stages.

For example, the pattern +`Lit(Bool(_)*)` isn't valid because the parameter type of the `Lit` variant of +the `Expr` enum is `Any` and therefore doesn't support repetition (`*`). As +another example, `Array( Lit(_)* )` is a valid pattern because the parameter of +`Array` is of type `Seq` which allows sequences and repetitions. + +> Note: names in the pattern syntax correspond to *PatternTree* enum +> **variants**. For example, the `Lit` in the pattern above refers to the `Lit` +> variant of the `Expr` enum (`Expr::Lit`), not the `Lit` enum. + +## The IsMatch Trait + +The pattern syntax and the *PatternTree* are independant of specific syntax tree +implementations (rust ast / hir, syn, ...). When looking at the different +pattern examples in the previous sections, it can be seen that the patterns +don't contain any information specific to a certain syntax tree implementation. +In contrast, clippy lints currently match against ast / hir syntax tree nodes +and therefore directly depend on their implementation. + +The connection between the *PatternTree* and specific syntax tree +implementations is the `IsMatch` trait. It defines how to match *PatternTree* +nodes against specific syntax tree nodes. A simplified implementation of the +`IsMatch` trait is shown below: + +```rust +pub trait IsMatch { + fn is_match(&self, other: &'o O) -> bool; +} +``` + +This trait needs to be implemented on each enum of the *PatternTree* (for the +corresponding syntax tree types). For example, the `IsMatch` implementation for +matching `ast::LitKind` against the *PatternTree's* `Lit` enum might look like +this: + +```rust +impl IsMatch for Lit { + fn is_match(&self, other: &ast::LitKind) -> bool { + match (self, other) { + (Lit::Char(i), ast::LitKind::Char(j)) => i.is_match(j), + (Lit::Bool(i), ast::LitKind::Bool(j)) => i.is_match(j), + (Lit::Int(i), ast::LitKind::Int(j, _)) => i.is_match(j), + _ => false, + } + } +} +``` + +All `IsMatch` implementations for matching the current *PatternTree* against +`syntax::ast` can be found +[here](https://github.com/fkohlgrueber/pattern-matching/blob/dfb3bc9fbab69cec7c91e72564a63ebaa2ede638/pattern-match/src/ast_match.rs). + + +# Drawbacks + +#### Performance + +The pattern matching code is currently not optimized for performance, so it +might be slower than hand-written matching code. Additionally, the two-stage +approach (matching against the coarse pattern first and checking for additional +properties later) might be slower than the current practice of checking for +structure and additional properties in one pass. For example, the following lint + +```rust +pattern!{ + pat_if_without_else: Expr = + If( + _, + Block( + Expr( If(_, _, ())#inner ) + | Semi( If(_, _, ())#inner ) + )#then, + () + ) +} +... +fn check_expr(&mut self, cx: &EarlyContext<'_>, expr: &ast::Expr) { + if let Some(result) = pat_if_without_else(expr) { + if !block_starts_with_comment(cx, result.then) { + ... + } +} +``` + +first matches against the pattern and then checks that the `then` block doesn't +start with a comment. Using clippy's current approach, it's possible to check +for these conditions earlier: + +```rust +fn check_expr(&mut self, cx: &EarlyContext<'_>, expr: &ast::Expr) { + if_chain! { + if let ast::ExprKind::If(ref check, ref then, None) = expr.node; + if !block_starts_with_comment(cx, then); + if let Some(inner) = expr_block(then); + if let ast::ExprKind::If(ref check_inner, ref content, None) = inner.node; + then { + ... + } + } +} +``` + +Whether or not this causes performance regressions depends on actual patterns. +If it turns out to be a problem, the pattern matching algorithms could be +extended to allow "early filtering" (see the [Early Filtering](#early-filtering) +section in Future Possibilities). + +That being said, I don't see any conceptual limitations regarding pattern +matching performance. + +#### Applicability + +Even though I'd expect that a lot of lints can be written using the proposed +pattern syntax, it's unlikely that all lints can be expressed using patterns. I +suspect that there will still be lints that need to be implemented by writing +custom pattern matching code. This would lead to mix within clippy's codebase +where some lints are implemented using patterns and others aren't. This +inconsistency might be considered a drawback. + + +# Rationale and alternatives + +Specifying lints using syntax tree patterns has a couple of advantages compared +to the current approach of manually writing matching code. First, syntax tree +patterns allow users to describe patterns in a simple and expressive way. This +makes it easier to write new lints for both novices and experts and also makes +reading / modifying existing lints simpler. + +Another advantage is that lints are independent of specific syntax tree +implementations (e.g. AST / HIR, ...). When these syntax tree implementations +change, only the `IsMatch` trait implementations need to be adapted and existing +lints can remain unchanged. This also means that if the `IsMatch` trait +implementations were integrated into the compiler, updating the `IsMatch` +implementations would be required for the compiler to compile successfully. This +could reduce the number of times clippy breaks because of changes in the +compiler. Another advantage of the pattern's independence is that converting an +`EarlyLintPass` lint into a `LatePassLint` wouldn't require rewriting the whole +pattern matching code. In fact, the pattern might work just fine without any +adaptions. + + +## Alternatives + +### Rust-like pattern syntax + +The proposed pattern syntax requires users to know the structure of the +`PatternTree` (which is very similar to the AST's / HIR's structure) and also +the pattern syntax. An alternative would be to introduce a pattern syntax that +is similar to actual Rust syntax (probably like the `quote!` macro). For +example, a pattern that matches `if` expressions that have `false` in their +condition could look like this: + +```rust +if false { + #[*] +} +``` + +#### Problems + +Extending Rust syntax (which is quite complex by itself) with additional syntax +needed for specifying patterns (alternations, sequences, repetisions, named +submatches, ...) might become difficult to read and really hard to parse +properly. + +For example, a pattern that matches a binary operation that has `0` on both +sides might look like this: + +``` +0 #[*:BinOpKind] 0 +``` + +Now consider this slightly more complex example: + +``` +1 + 0 #[*:BinOpKind] 0 +``` + +The parser would need to know the precedence of `#[*:BinOpKind]` because it +affects the structure of the resulting AST. `1 + 0 + 0` is parsed as `(1 + 0) + +0` while `1 + 0 * 0` is parsed as `1 + (0 * 0)`. Since the pattern could be any +`BinOpKind`, the precedence cannot be known in advance. + +Another example of a problem would be named submatches. Take a look at this +pattern: + +```rust +fn test() { + 1 #foo +} +``` + +Which node is `#foo` referring to? `int`, `ast::Lit`, `ast::Expr`, `ast::Stmt`? +Naming subpatterns in a rust-like syntax is difficult because a lot of AST nodes +don't have a syntactic element that can be used to put the name tag on. In these +situations, the only sensible option would be to assign the name tag to the +outermost node (`ast::Stmt` in the example above), because the information of +all child nodes can be retrieved through the outermost node. The problem with +this then would be that accessing inner nodes (like `ast::Lit`) would again +require manual pattern matching. + +In general, Rust syntax contains a lot of code structure implicitly. This +structure is reconstructed during parsing (e.g. binary operations are +reconstructed using operator precedence and left-to-right) and is one of the +reasons why parsing is a complex task. The advantage of this approach is that +writing code is simpler for users. + +When writing *syntax tree patterns*, each element of the hierarchy might have +alternatives, repetitions, etc.. Respecting that while still allowing +human-friendly syntax that contains structure implicitly seems to be really +complex, if not impossible. + +Developing such a syntax would also require to maintain a custom parser that is +at least as complex as the Rust parser itself. Additionally, future changes in +the Rust syntax might be incompatible with such a syntax. + +In summary, I think that developing such a syntax would introduce a lot of +complexity to solve a relatively minor problem. + +The issue of users not knowing about the *PatternTree* structure could be solved +by a tool that, given a rust program, generates a pattern that matches only this +program (similar to the clippy author lint). + +For some simple cases (like the first example above), it might be possible to +successfully mix Rust and pattern syntax. This space could be further explored +in a future extension. + +# Prior art + +The pattern syntax is heavily inspired by regular expressions (repetitions, +alternatives, sequences, ...). + +From what I've seen until now, other linters also implement lints that directly +work on syntax tree data structures, just like clippy does currently. I would +therefore consider the pattern syntax to be *new*, but please correct me if I'm +wrong. + +# Unresolved questions + +#### How to handle multiple matches? + +When matching a syntax tree node against a pattern, there are possibly multiple +ways in which the pattern can be matched. A simple example of this would be the +following pattern: + +```rust +pattern!{ + my_pattern: Expr = + Array( _* Lit(_)+#literals) +} +``` + +This pattern matches arrays that end with at least one literal. Now given the +array `[x, 1, 2]`, should `1` be matched as part of the `_*` or the `Lit(_)+` +part of the pattern? The difference is important because the named submatch +`#literals` would contain 1 or 2 elements depending how the pattern is matched. +In regular expressions, this problem is solved by matching "greedy" by default +and "non-greedy" optionally. + +I haven't looked much into this yet because I don't know how relevant it is for +most lints. The current implementation simply returns the first match it finds. + +# Future possibilities + +#### Implement rest of Rust Syntax + +The current project only implements a small part of the Rust syntax. In the +future, this should incrementally be extended to more syntax to allow +implementing more lints. Implementing more of the Rust syntax requires extending +the `PatternTree` and `IsMatch` implementations, but should be relatively +straight-forward. + +#### Early filtering + +As described in the *Drawbacks/Performance* section, allowing additional checks +during the pattern matching might be beneficial. + +The pattern below shows how this could look like: + +```rust +pattern!{ + pat_if_without_else: Expr = + If( + _, + Block( + Expr( If(_, _, ())#inner ) + | Semi( If(_, _, ())#inner ) + )#then, + () + ) + where + !in_macro(#then.span); +} +``` + +The difference compared to the currently proposed two-stage filtering is that +using early filtering, the condition (`!in_macro(#then.span)` in this case) +would be evaluated as soon as the `Block(_)#then` was matched. + +Another idea in this area would be to introduce a syntax for backreferences. +They could be used to require that multiple parts of a pattern should match the +same value. For example, the `assign_op_pattern` lint that searches for `a = a +op b` and recommends changing it to `a op= b` requires that both occurrances of +`a` are the same. Using `=#...` as syntax for backreferences, the lint could be +implemented like this: + +```rust +pattern!{ + assign_op_pattern: Expr = + Assign(_#target, Binary(_, =#target, _) +} +``` + +#### Match descendant + +A lot of lints currently implement custom visitors that check whether any +subtree (which might not be a direct descendant) of the current node matches +some properties. This cannot be expressed with the proposed pattern syntax. +Extending the pattern syntax to allow patterns like "a function that contains at +least two return statements" could be a practical addition. + +#### Negation operator for alternatives + +For patterns like "a literal that is not a boolean literal" one currently needs +to list all alternatives except the boolean case. Introducing a negation +operator that allows to write `Lit(!Bool(_))` might be a good idea. This pattern +would be eqivalent to `Lit( Char(_) | Int(_) )` (given that currently only three +literal types are implemented). + +#### Functional composition + +Patterns currently don't have any concept of composition. This leads to +repetitions within patterns. For example, one of the collapsible-if patterns +currently has to be written like this: + +```rust +pattern!{ + pat_if_else: Expr = + If( + _, + _, + Block_( + Block( + Expr((If(_, _, _?) | IfLet(_, _?))#else_) | + Semi((If(_, _, _?) | IfLet(_, _?))#else_) + )#block_inner + )#block + ) | + IfLet( + _, + Block_( + Block( + Expr((If(_, _, _?) | IfLet(_, _?))#else_) | + Semi((If(_, _, _?) | IfLet(_, _?))#else_) + )#block_inner + )#block + ) +} +``` + +If patterns supported defining functions of subpatterns, the code could be +simplified as follows: + +```rust +pattern!{ + fn expr_or_semi(expr: Expr) -> Stmt { + Expr(expr) | Semi(expr) + } + fn if_or_if_let(then: Block, else: Opt) -> Expr { + If(_, then, else) | IfLet(then, else) + } + pat_if_else: Expr = + if_or_if_let( + _, + Block_( + Block( + expr_or_semi( if_or_if_let(_, _?)#else_ ) + )#block_inner + )#block + ) +} +``` + +Additionally, common patterns like `expr_or_semi` could be shared between +different lints. + +#### Clippy Pattern Author + +Another improvement could be to create a tool that, given some valid Rust +syntax, generates a pattern that matches this syntax exactly. This would make +starting to write a pattern easier. A user could take a look at the patterns +generated for a couple of Rust code examples and use that information to write a +pattern that matches all of them. + +This is similar to clippy's author lint. + +#### Supporting other syntaxes + +Most of the proposed system is language-agnostic. For example, the pattern +syntax could also be used to describe patterns for other programming languages. + +In order to support other languages' syntaxes, one would need to implement +another `PatternTree` that sufficiently describes the languages' AST and +implement `IsMatch` for this `PatternTree` and the languages' AST. + +One aspect of this is that it would even be possible to write lints that work on +the pattern syntax itself. For example, when writing the following pattern + + +```rust +pattern!{ + my_pattern: Expr = + Array( Lit(Bool(false)) Lit(Bool(false)) ) +} +``` + +a lint that works on the pattern syntax's AST could suggest using this pattern +instead: + +```rust +pattern!{ + my_pattern: Expr = + Array( Lit(Bool(false)){2} ) +} +``` + +In the future, clippy could use this system to also provide lints for custom +syntaxes like those found in macros. diff --git a/src/tools/clippy/clippy_dev/src/new_lint.rs b/src/tools/clippy/clippy_dev/src/new_lint.rs index 9e15f1504fa..ec7f1dd0d84 100644 --- a/src/tools/clippy/clippy_dev/src/new_lint.rs +++ b/src/tools/clippy/clippy_dev/src/new_lint.rs @@ -120,7 +120,7 @@ fn add_lint(lint: &LintData<'_>, enable_msrv: bool) -> io::Result<()> { let new_lint = if enable_msrv { format!( - "store.register_{lint_pass}_pass(move |{ctor_arg}| Box::new({module_name}::{camel_name}::new(msrv)));\n ", + "store.register_{lint_pass}_pass(move |{ctor_arg}| Box::new({module_name}::{camel_name}::new(msrv())));\n ", lint_pass = lint.pass, ctor_arg = if lint.pass == "late" { "_" } else { "" }, module_name = lint.name, @@ -238,10 +238,9 @@ fn get_lint_file_contents(lint: &LintData<'_>, enable_msrv: bool) -> String { result.push_str(&if enable_msrv { formatdoc!( r#" - use clippy_utils::msrvs;
