https://issues.dlang.org/show_bug.cgi?id=23673 Issue ID: 23673 Summary: import dependencies should identify how they were imported Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: schveiguy@gmail.com When you get a circular dependency error, you receive a printout of the cycle for the dependencies, something like: a->b->c->a which shows the import graph of why the cycle occurred. However, this doesn't tell you how each dependency was imported. The compiler could easily store the file/line that caused an import to be added as a dependency, which would further help identify how the cycle happened. Sometimes, when instantiating a template, you have an import you don't even see in a module. So knowing that a imported b because a template in x had an import of b, and a instantiated that template would go a long way to lower confusion. This might not be something to do in normal builds, but maybe in debug builds? Or maybe with a switch to store extra dependency info? -- |
