* fixes #22166; adds sideeffects for `close` and `setFilePos` (#23380)ringabout2024-03-091-2/+2
| | | fixes #22166
* fix `isAbsolute` broken when `nodejs` on Windows (#23365)litlighilit2024-03-041-3/+3
| | | | | | | | | | | When target is nodejs, `isAbsolute` used to only check in the POSIX flavor, i.e. for js backend on Windows, ```nim isAbsolute(r"C:\Windows") == false ``` This fixes it.

* Update cmdline.nim, fix broken (dragged) doc-reference for getAppFile… ↵litlighilit2024-01-281-4/+4
| | | | | | | | (#23262) In doc, there are 4 references for `getAppFilename` `getAppFilename` is still in `os`, but the references refer it as if it's in the current module `cmdline`
* Deprecate asm stmt for js target (#23149)ASVIEST2024-01-022-10/+10
| | | | | | | | | | | | | | | | | | | | | | | 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>
* allow non var deinit for locks and conds: alternative way (#23099)ringabout2023-12-191-14/+14

* Silence several Hint[Performance] warnings (#23003)c-blake2023-11-291-1/+1
| | | | With `--mm:arc` one gets the "implicit copy; if possible, rearrange your program's control flow" `Performance` warnings without these `move`s.
* reserve `sysFatal` for `Defect` (#22158)Jacek Sieka2023-11-061-9/+6
| | | | | | | | Per manual, `panics:on` affects _only_ `Defect`:s - thus `sysFatal` should not redirect any other exceptions. Also, when `sysFatal` is used in `nimPanics` mode, it should use regular exception handling pipeline to ensure exception hooks are called consistently for all raised defects.
* complete std prefixes for stdlib (#22887)ringabout2023-10-3035-52/+52

* explicitly import using `std/` in `tempfiles.nim` (#22851)Vindaar2023-10-201-1/+1
| | | | | At least on modern Nim `tempfiles` is not usable if the user has https://github.com/oprypin/nim-random installed, because the compiler picks the nimble path over the stdlib path (apparently).

* NIR: Nim intermediate representation (#22777)Andreas Rumpf2023-10-111-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Theoretical Benefits / Plans: - Typed assembler-like language. - Allows for a CPS transformation. - Can replace the existing C backend by a new C backend. - Can replace the VM. - Can do more effective "not nil" checking and static array bounds checking. - Can be used instead of the DFA. - Easily translatable to LLVM. - Reasonably easy to produce native code from. - Tiny memory consumption. No pointers, no cry. **In very early stages of development.** Todo: - [x] Map Nim types to IR types. - [ ] Map Nim AST to IR instructions: - [x] Map bitsets to bitops. - [ ] Implement string cases. - [ ] Implement range and index checks. - [x] Implement `default(T)` builtin. - [x] Implement multi string concat. - [ ] Write some analysis passes. - [ ] Write a backend. - [x] Integrate into the compilation pipeline.

* copyFile with POSIX_FADV_SEQUENTIAL (#22776)Juan Carlos2023-10-011-0/+8
| | | | | | | | | | | - Continuation of https://github.com/nim-lang/Nim/pull/22769 - See https://pubs.opengroup.org/onlinepubs/9699919799/functions/posix_fadvise.html - The code was already there in `std/posix` since years ago. 3 line diff. --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>
* copyFile with bufferSize instead of hardcoded value (#22769)Juan Carlos2023-09-301-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - `copyFile` allows to specify `bufferSize` instead of hardcoded wrong value. Tiny diff. # Performance - 1200% Performance improvement. # Check it yourself Execute: ```bash for i in $(seq 0 10); do bs=$((1024*2**$i)) printf "%7s Kb\t" $bs timeout --foreground -sINT 2 dd bs=$bs if=/dev/zero of=/dev/null 2>&1 | sed -n 's/.* \([0-9.,]* [GM]B\/s\)/\1/p' done ``` (This script can be ported to PowerShell for Windows I guess, it works in Windows MinGW Bash anyways). # Stats - Hardcoded `8192` or `8000` Kb bufferSize gives `5` GB/s. - Setting `262144` Kb bufferSize gives `65` GB/s (script suggestion). --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>

* avoid `AnyEnumConv` warning in `genEnumCaseStmt` (#22061)Etan Kissling2023-06-101-10/+11
| | | | | | | When parsing enums from strings using `genEnumCaseStmt`, `AnyEnumConv` warnings are generated due to conversion from integer value. It seems possible meanwhile to refer to the actual `enum` value by symbol instead of being required to do the conversion from `ord`, even when the `enum` is defined in a `block`.
