2023-04-19Fix several issues in build system module importation logicmodule-importBoris Kolpackov1-4/+7
2022-12-14Improve empty simple value to empty list of names reduction heuristicsBoris Kolpackov1-1/+1
Specifically, do not reduce typed RHS empty simple values for prepend/append and additionally for assignment provided LHS is typed and is a container.
2022-12-12Adapt to dir_iterator API changeKaren Arutyunov1-2/+18
2022-12-02Fail if scope or target qualification in variable expansion is unknownBoris Kolpackov1-1/+5
There are three options here: we can "fall through" to an outer scope (there is always the global scope backstop; this is the old semantics, sort of), we can return NULL straight away, or we can fail. It feels like in most cases unknown scope or target is a mistake and doing anything other than failing is just making things harder to debug.
2022-11-29Move buildfiles to root_extra, use vector instead of unordered_setBoris Kolpackov1-2/+2
2022-11-16Initial low verbosity diagnostics reworkBoris Kolpackov1-8/+15
2022-11-09Make process exit diagnostics in executable metadata extraction consistentBoris Kolpackov1-11/+30
2022-11-08Make process exit diagnostics consistentBoris Kolpackov1-0/+2
In particular, we now always print error message on non-0 exit except in cases where such exit is ignored.
2022-10-13Work around Clang 6, 7 codegen issuesBoris Kolpackov1-33/+25
2022-10-13Optimize by going straight to public variable pool where applicableBoris Kolpackov1-1/+3
2022-10-13Switch to public/private variables modelBoris Kolpackov1-4/+6
Now unqualified variables are project-private and can be typified.
2022-10-11Factor variable patterns out of variable_pool into separate variable_patternsBoris Kolpackov1-1/+1
We have patterns only for the public variables pool.
2022-10-10Preparatory work for public/private variable distinctionBoris Kolpackov1-3/+10
We still always use the public var_pool from context but where required, all access now goes through scope::var_pool().
2022-06-28Add support for rule-specific import phase 2Boris Kolpackov1-10/+80
For example: import! [metadata, rule_hint=cxx.link] lib = libhello%lib{hello}

2021-10-15Allow explicit amalgamation by simple projectsBoris Kolpackov1-9/+8
2021-09-02Add diag_frame around export stub loadingBoris Kolpackov1-2/+11
This gives the location of the importer in case the export stub issues any diagnostics.

2020-07-10Add support for project-local importationBoris Kolpackov1-11/+19
An import without a project name or with the same name as the importing project's is now treated as importation from the same project. For example, given the libhello project that exports the lib{hello} target, a buildfile for an executable in the same project instead of doing something like this: include ../libhello/ exe{hello}: ../libhello/lib{hello} Can now do this: import lib = libhello%lib{hello} Or: import lib = lib{hello} And then: exe{hello}: $lib Note that a target in project-local importation must still be exported in the project's export stub. In other words, project-local importation goes through the same mechanisms as normal import.
