Donny/강동윤	7aab945a21	perf(es): Cache current_dir() system calls (#9683) ... **Description:** Cache `current_dir()` system calls.

Donny/강동윤	581aafb4df	perf(visit): Introduce Pass API and adjust visitor APIs for it (#9680) ... **Description:** - `Pass`: `FnMut(&mut Program)`. **Breaking Changes:** - `chain!`: Use a tuple instead. You can replace all `chain!(` with `(` with IDE feature and it will work. - `chain!` with 13 or more args: Use nested tuples for items after 13th element. **Related issue:** - Related to https://github.com/swc-project/swc/issues/9601	2024-10-29 11:25:16 +09:00

CPunisher	7344a638b5	feat(es/minifier): Optimize switch with side effect and termination tests (#9677) ... **Description:** This is learnt from https://github.com/terser/terser/pull/1044 **Key point:** all the cases (statements) after the last side-effect and non-terminated one are useless. There are also some points on whether a statement is side-effect free: - **Var declaration:** I think var declaration always contains side effect. - **Function declaration:** In non-strict mode, function declaration is same as var declaration. In strict mode, function is declared in enclosing block scope, so it's side-effect free. But there is a bad case when we call the function before it is declared in the switch case: ```js "use strict"; const k = (() => { let x = 1; switch (x) { case y(): case x: { async function y() { console.log(123); } } } return x; })(); ``` **This is an existing bug.** I'm not sure whether we should fix it since it is a very bad code and I also find some similar bad cases with terser. ~I'm also not sure it's appropriate to introduce context variable `in_strict` for `StmtExt:: may_have_side_effects`, because `in_strict` could change from `false` to `true`. But this is a **conservative** mistake and does not break the program. Maybe we should use visitor for context-aware side effect checker in the future.~ **Related issue:** - Closes https://github.com/swc-project/swc/issues/8953	2024-10-29 10:39:05 +09:00
David Sherret	2bbd1e8485	feat(es/parser): Ability to get script's potential module errors (#9682) ... **Description:** In Deno I'm now parsing stuff as a program more often because I sometimes now need to discover if something is a script or es module by looking at the contents. A problem is that the module errors are discarded when parsing as a script, but I still might need them later if I discover the program the program should be treated as an ES module. **BREAKING CHANGE:** Adds a new method to the `Tokens` trait.	2024-10-29 09:50:14 +09:00

CPunisher	f70b842c55	feat(es/minifier): Implement optional catch binding (#9657) ... **Description:** I think removing `!v.declared_as_catch_param` is safe, since I can't think of a bad case: 1. for the vars in the params of catch-clause, we prevent the removal if `self.options.ecma < EsVersion::Es2019 || !self.options.unused` is not satisfied. 2. for the usages or re-declarations with the same var name in the body of catch-clause, I think it's safe to remove them. **Related issue:** - Closes https://github.com/swc-project/swc/issues/8966	2024-10-20 18:42:38 +09:00

Levi	88a2186ba4	feat(es/minifier): Support unary negate in cast_to_number (#9642) ... **Description:** Adds support for `-` in `cast_to_number`. Before it only worked if `arg` is `Infinity`. Now it uses a recursive call on `arg` so it works for expressions like `-5`, `-[]` etc. This change is important because negative number literals (e.g. `-5`) are a `UnaryExpr` with `op`=`-` & `arg`=`5`, unless you apply `expr_simplifier` pass or something else that uses it.	2024-10-15 08:00:39 +09:00

Levi	bfea322351	feat(es/testing): Parse test code as a Program instead of a Module (#9623) ... **Description:** This PR addresses the issue described in https://github.com/swc-project/swc/issues/8713 **BREAKING CHANGE:** Will break unit tests that use `fold_module`/`visit_module`/`visit_mut_module` if the visitor is intended to work for both modules and scripts instead of using `fold_program`/`visit_program`/`visit_mut_program`. When creating visitors, you should use `fold_program`/`visit_program`/`visit_mut_program` if you simply want to visit the top-level node. When creating tests, the input source code will be parsed using `parse_program` by default. If you need to parse it as a `Module`, you can use `module: Some(true)` in `FixtureTestConfig` (or with `test!(module, ..)`), which will parse it as a `Program::Module`, or `Some(false)` for `Program::Script`. `None` will use `parse_program` (`parse_program` will auto-detect the underlying type).	2024-10-08 13:58:58 +09:00
