* rework `wasMoved`, `move` on the JS backend (#23577)ringabout2024-05-081-31/+0
| | | | | `reset`, `wasMoved` and `move` doesn't support primitive types, which generate `null` for these types. It is now produce `x = default(...)` in the backend. Ideally it should be done by ast2ir in the future
* fixes #4695; closure iterators support for JS backend (#23493)ringabout2024-04-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | fixes #4695 ref https://github.com/nim-lang/Nim/pull/15818 Since `nkState` is only for the main loop state labels and `nkGotoState` is used only for dispatching the `:state` (since https://github.com/nim-lang/Nim/pull/7770), it's feasible to rewrite the loop body into a single case-based dispatcher, which enables support for JS, VM backend. `nkState` Node is replaced by a label and Node pair and `nkGotoState` is only used for intermediary processing. Backends only need to implement `nkBreakState` and `closureIterSetupExc` to support closure iterators. pending https://github.com/nim-lang/Nim/pull/23484 <del> I also observed some performance boost for C backend in the release mode (not in the danger mode though, I suppose the old implementation is optimized into computed goto in the danger mode) </del> allPathsAsgnResult???

| | | | | | | | fixes #4299 fixes #12492 fixes #10849 It binds `function` with `env`: `function.bind(:env)` to ease codegen for now
* Deprecate asm stmt for js target (#23149)ASVIEST2024-01-021-84/+84
| | | | | | | | | | | | | | | | | | | | | | | why ? - We already have an emit that does the same thing - The name asm itself is a bit confusing, you might think it's an alias for asm.js or something else. - The asm keyword is used differently on different compiler targets (it makes it inexpressive). - Does anyone (other than some compiler libraries) use asm instead of emit ? If yes, it's a bit strange to use asm somewhere and emit somewhere. By making the asm keyword for js target deprecated, there would be even less use of the asm keyword for js target, reducing the amount of confusion. - New users might accidentally use a non-universal approach via the asm keyword instead of emit, and then when they learn about asm, try to figure out what the differences are. see https://forum.nim-lang.org/t/10821 --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>

* many bugfixes for js (#14158)hlaaftana2020-04-291-9/+16
| | | | | | | | | | | | | * many bugfixes for js fixes #12672, fixes #14153, closes #14123, closes #11331, fixes #11783, fixes #13966, fixes #14087, fixes #14117, closes #12256. mostly fixes the fact that it was allowed to assign to newly created temp variables. additionally attempts to get rid of null initialized seqs/strings (though they might pop up here and there); this simplifies a lot of things and makes code size smaller. even if null seqs/strings pop up here and there it's still better than all those bugs existing. * formatting fixes * CI fixes * more CI fixes
* Error -> Defect for defects (#13908)Jacek Sieka2020-04-281-8/+8
| | | | | | | | | | | | | | * Error -> Defect for defects The distinction between Error and Defect is subjective, context-dependent and somewhat arbitrary, so when looking at an exception, it's hard to guess what it is - this happens often when looking at a `raises` list _without_ opening the corresponding definition and digging through layers of inheritance. With the help of a little consistency in naming, it's at least possible to start disentangling the two error types and the standard lib can set a good example here.
