Revision 63e365feb8692b9d7cb5298954c26ab7af268171 authored by Keno Fischer on 23 March 2024, 05:18:55 UTC, committed by GitHub on 23 March 2024, 05:18:55 UTC
Currently, in order to give the nice prompt for missing packages, we
look for any `using`/`import` statements in the AST before evaluation.
However, this misses any `using` statements introduced by macros:
```
julia> using Pkg
julia> using BenchmarkTools
│ Package BenchmarkTools not found, but a package named BenchmarkTools is
│ available from a registry.
│ Install package?
│ (@v1.11) pkg> add BenchmarkTools
└ (y/n/o) [y]: n
ERROR: ArgumentError: Package BenchmarkTools not found in current path.
- Run `import Pkg; Pkg.add("BenchmarkTools")` to install the BenchmarkTools package.

Generally, it doesn't matter, but embedded DSLs may want to do this kind
of thing, so we might as well try to support it. 1 parent 6172020
