depgraph missing

[jstover79]

There is no file named "depgraph". Is that file supposed to be in there somewhere or maybe there are missing instructions on how to create it?

You will need to compile LatexDepGraph.hs on your machine and name the executable depgraph.

Aha! This is progress! Maybe not an issue on your end, but here is what ghc gives me:

$ ghc LatexDepGraph
[1 of 4] Compiling Utilities        ( Utilities.hs, Utilities.o )

Utilities.hs:17:1: error:
    Failed to load interface for ‘Data.Hashable’
    Use -v to see a list of the files searched for.

I assume this is not an issue on your end, and in that case, you can close this issue. Thanks for any hints, if you have any quick ideas on this -- but otherwise, thanks for the quick response!

You can try cabal install hashable which installs the package globally.
Alternatively (and really this is preferred to keep the project self-contained, though I did not do it at the time), you can set up the project with stack and do stack install hashable.
Ditto with any other missing package.

I got it with installing cabal, updating it, and then cabal install hashable. Thanks!

I was able to install a few other things with cabal, but here are two I can't figure out what to install for, any hints? I don't want to take too much of your time, so no pressure for a response as this isn't an issue with your code presumably.

$ ghc LatexDepGraph
[2 of 4] Compiling ParseUtilities   ( ParseUtilities.hs, ParseUtilities.o )

ParseUtilities.hs:16:1: error:
    Failed to load interface for ‘Data.Graph.Inductive’
    Use -v to see a list of the files searched for.

ParseUtilities.hs:17:1: error:
    Failed to load interface for ‘Data.List.Ordered’
    Use -v to see a list of the files searched for.

Search for the package and find the (lower-case) name that it's listed under. For example Data.Graph.Inductive gives https://hackage.haskell.org/package/fgl-5.7.0.3/docs/Data-Graph-Inductive-Graph.html, so the package name is actually fgl.

[jstover79]

Ok, I was able to figure out which packages to install and compiling depgraph worked! I ran the code and go t this:

$ ./LatexDepGraph stover_mpp.tex mpp_out.dot dot.exe -Tpdf mpp_out.dot > mpp_out.pdf
LatexDepGraph: Prelude.!!: index too large

Also, I think there is a typo in the dep file and your instructions as it calls for depgraph, but mine was named LatexDepGraph it seems.

[holdenlee]

Looks like I overrode the default name and compiled it to depgraph on my machine, hence the discrepancy.
I wouldn't know what the problem is without looking at the tex file. Unfortunately the parser is far from a full LaTeX parser, so there are some things that throw it off.

Thank you so much for the help!
