Option `--filter pandoc-citeproc` causes pandoc: PATH: getEnv: does not exist (no environment variable)

[regisd]

This target works:

pandoc(
    name = "html",
    src = ":manual_mdx",
    from_format = "markdown",
    output = "manual.html",
    to_format = "html",
)

This target fails:

pandoc(
    name = "html",
    src = ":manual_mdx",
    from_format = "markdown",
    output = "manual.html",
    to_format = "html",
    options = ["--filter", "pandoc-citeproc"],
)

It looks like pandoc-citeproc is part of the same tarball/zip as pandoc, so it should be relatively simple to add support for this. That said, we don't use this feature at Prodrive, meaning we'd rather have that such a feature is contributed.

Sorry for the long delay between opening this issue and merging the changes with master, but this issue is resolved now after I merged #1 with master.

[regisd]

No worries about delay, we are all doing this on our spare time. However, I don't think PR 1 has anything to do with this issue. I tried and I still have:

ERROR: /Users/regis/Projects/jflex/docs/BUILD:9:1: Pandoc docs/manual.html failed (Exit 1) pandoc failed: error executing command

Can you reopen the issue?

Ah, I see. I thought this issue was related to #1 because it said regisd mentioned this issue on Oct 15, 2018, my bad!

I believe no one within our organization currently uses bazel-pandoc like this, because we did not run into this issue yet. Feel free to contribute the needed changes.

[regisd]

Yes, you can reassign the issue to me, but I'm not going to look into it anytime soon, tbh.
