Possibility for reverse search dashboard (similar to conda repoquery whoneeds)?

[matthewfeickert]

👋 The dashboard (which I learned about in conda-forge/cuda-feedstock#61 (comment)) is super nice! If I could put in a stretch goal of a feature request, it would be useful to add a view that would allow for you to type in a conda-forge package name and have it list for you all the packages on conda-forge that depend on that package. This is basically what conda repoquery whoneeds does already, so as an example of what I'm suggesting, in the dashboard I could type in awkward and it would return to me output similar to

$ micromamba repoquery whoneeds --channel conda-forge awkward > out.txt  # Need to strip off the headers first
$ tail -n +$(($(grep -n -m 1 "Depends" out.txt | grep -Po '^[0-9]+')+2)) out.txt | awk '{print $1}' | sort --unique
akimbo
awkward-numba
awkward-pandas
cabinetry
clouddrift
coffea
cuda_histogram
dask-awkward
fastjet
km3io
km3pipe
lbapcommon
lhcbdirac
pykealib
pylhe
ragged
rubin-env-extras
rubin-env-rsp
scikit-hep
tiled-base
uproot
uproot-base
uproot-browser
uproot-methods

In situations where there's no package that includes the target package as run requirement (like cuda-nvtx-dev)

$ micromamba repoquery whoneeds --channel conda-forge cuda-nvtx-dev
Getting repodata from channels...

Try looking remotely with '--remote'.

the dashboard would note that there are no packages on conda-forge that required that target package.
