* NIR: Nim intermediate representation (#22777)Andreas Rumpf2023-10-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix/improve handling of forward declarations in nimsuggest (#20493)Ivan Yonchovski2022-10-061-2/+2
| | | | | | | | | | | | | | | | | * Fix/improve handling of forward declarations in nimsuggest - ideUse now works fine when invoked on the implementation - implemented ideDeclaration to make cover lsp feature textDocument/declaration - fixed performance issue related to deduplicating symbols. Now the deduplication happens after the symbols are filtered. As a alternative we might change the way cached symbols are stored(e. g. use set). - I also fixed the way globalSymbols work. Now it will sort the responses based on the match location to make sure that the results are sorted in user friendly way. * Update nimsuggest/nimsuggest.nim Co-authored-by: Andreas Rumpf <rumpf_a@web.de> Co-authored-by: Andreas Rumpf <rumpf_a@web.de>
* [nimsuggest] fix def call on identifier 2 times on the line (#20228)Ivan Yonchovski2022-08-301-9/+13
| | | | | | | - apparently TLineInfo's implementation of `==` ignores the column. After I fixed the code to use exact TLineInfo comparison I fixed several other issues hidden by that issue. - Replaced `tuple[sym, info]` with `SymInfoPair`

* Initial implementation of nimsuggest v3 (#19826)Ivan Yonchovski2022-06-131-13/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Initial implementation of nimsuggest v3 Rework `nimsuggest` to use caching to make usage of ide commands more efficient. Previously, all commands no matter what the state of the process is were causing clean build. In the context of Language Server Protocol(LSP) and lsp clients this was causing perf issues and overall instability. Overall, the goal of v3 is to fit to LSP Server needs - added two new commands: - `recompile` to do clean compilation - `changed` which can be used by the IDEs to notify that a particular file has been changed. The later can be utilized when using LSP file watches. - `globalSymbols` - searching global references - added `segfaults` dependency to allow fallback to clean build when incremental fails. I wish the error to be propagated to the client so we can work on fixing the incremental build failures (typically hitting pointer) - more efficient rebuild flow. ATM incremental rebuild is triggered when the command needs that(i. e. it is global) while the commands that work on the current source rebuild only it Things missing in this PR: - Documentation - Extensive unit testing. Although functional I still see this more as a POC that this approach can work. Next steps: - Implement `sug` request. - Rework/extend the protocol to allow better client/server communication. Ideally we will need push events, diagnostics should be restructored to allow per file notifications, etc. - implement v3 test suite. - better logging * Add tests for v3 and implement ideSug * Remove typeInstCache/procInstCache cleanup * Add ideChkFile command * Avoid contains call when adding symbol info * Remove log * Remove segfaults
* Refactor and doc package handling, module name mangling (#19821)quantimnot2022-05-301-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Refactor and doc package handling, module name mangling * Consolidate, de-duplicate and extend package handling * Alter how duplicate module names of a package are handled * Alter how module names are mangled * Fix crash when another package is named 'stdlib' (test case added) * Doc what defines a package in the manual Modules with duplicate names within a package used to be given 'fake' packages to resolve conflicts. That prevented the ability to discern if a module belonged to the current project package or a foreign package. They now have the proper package owner and the names are mangled in a consistent manner to prevent codegen clashes. All module names are now mangled the same. Stdlib was treated special before, but now it is same as any other package. This fixes a crash when a foreign package is named 'stdlib'. Module mangling is altered for both file paths and symbols used by the backends. Removed an unused module name to package mapping that may have been intended for IC. The mapping was removed because it wasn't being used and was complicating the issue of package modules with duplicate names not having the proper package owner assigned. * Fix some tests * Refactor `packagehandling` * Remove `packagehandling.withPackageName` and its uses * Move module path mangling from `packagehandling` to `modulepaths` * Move `options.toRodFile` to `ic` to break import cycle * Changed import style to match preferred style Co-authored-by: quantimnot <quantimnot@users.noreply.github.com>
