I was wondering whether an arbitrary string is allowed between .d. and .ts, or if only a restricted set of characters are allowed. It turns out any arbitrary string is allowed here:
tl;dr this regexp sounds correct to me.

Outdated

What is this warning? Is it about the module value not being aligned with the moduleResolution value?
Shouldn't we resolve it instead?

Resolved! I was not sure if I should update this to include the warning, or this other statement https://github.com/rollup/plugins/pull/1949/changes#diff-9b47757e1347eae5ab5cefedce0669826e925f9b073a02815b9507b782f2211bL1540 since changing the module changes how the code is output in the test.

What the test cares about is the unresolved import, so I'd say it's better if we avoid any other unnecessary noise :P

Nit: could we avoid the cast here by using new Map<string, ExtendedConfigCacheEntry>() instead?

Thanks, I missed that when changing it

Looks good apart from this minor warning-related comment!

These new changes look good! Can you squash them into the commits that introduced what they're fixing? |

Done, I squashed the changes into the typescript upgrade, so now there are only the 3 commits I initially added. Let me know if you want them combined as well |

@shellscape, would you mind having a look? |

List any relevant issue numbers: resolves #1858
Description
This PR updates the regular expression used to detect declaration files (
*.d.ts) to include declaration files for arbitrary extensions, such as the ones allowed with theallowArbitraryExtensionscompiler option (*.d.*.ts). By including these in the regex, they are not resolved and therefore prevent the error displayed in #1858.Also, in order to add a test for this behavior, the typescript version in the dev dependencies was upgraded to v5 and therefore some other pieces of code had to be changed.
