numhask-bench: "Did not find executable at specified path"

[Magalame]

Running stack build --exec "$(stack path --local-install-root)/bin/numhask-bench" --exec "$(stack path --local-bin)/pandoc -f markdown -i other/bench_.md -t markdown -o readme.md --filter pandoc-include --mathjax" --file-watch
It eventually fails with Did not find executable at specified path: /home/user/Projects/numhask/.stack-work/install/x86_64-linux/nightly-2019-03-15/8.6.4/bin/numhask-bench

The benchmarking relies on pandoc to produce the readme.md markdown file. For the latter part of the command to work, you'll need to:

stack install pandoc
stack install pandoc-include

if you dont have pandoc installed.

Fixed in master with 19af1bd

Seems like this might be more of an error with pandoc-include, but still:

dunno. but pandoc-include is for post-processing, so results will be in the other directory.

[tonyday567]

steindani/pandoc-include#15

This is the error. pandoc-include looks abandoned to me.

[Magalame]

Hmm, so there is no way to fix it? Since the benches rely on pandoc-include?

[tonyday567]

Just have to bump stack back on the resolver, so something like:

stack install pandoc-install --resolver=lts-10.10

[tonyday567]

The better solution is to wrap pandoc and pandoc-include inside the existing report production code, but then the bug in pandoc-include hardens, as it's tough to patch an abandoned library.

[tonyday567]

Had to rewind a bit furher.

stack install pandoc-include --resolver=lts-8.9 worked for me.
