John MacFarlane 2415b2680a Test suite: a more robust way of testing the executable.
Mmny of our tests require running the pandoc
executable. This is problematic for a few different reasons.
First, cabal-install will sometimes run the test suite
after building the library but before building the executable,
which means the executable isn't in place for the tests.
One can work around that by first building, then building
and running the tests, but that's fragile.  Second,
we have to find the executable. So far, we've done that
using a function findPandoc that attempts to locate it
relative to the test executable (which can be located
using findExecutablePath).  But the logic here is delicate
and work with every combination of options.

To solve both problems, we add an `--emulate` option to
the `test-pandoc` executable.  When `--emulate` occurs
as the first argument passed to `test-pandoc`, the
program simply emulates the regular pandoc executable,
using the rest of the arguments (after `--emulate`).
Thus,

    test-pandoc --emulate -f markdown -t latex

is just like

    pandoc -f markdown -t latex

Since all the work is done by library functions,
implementing this emulation just takes a couple lines
of code and should be entirely reliable.

With this change, we can test the pandoc executable
by running the test program itself (locatable using
findExecutablePath) with the `--emulate` option.
This removes the need for the fragile `findPandoc`
step, and it means we can run our integration tests
even when we're just building the library, not the
executable.

Part of this change involved simplifying some complex
handling to set environment variables for dynamic
library paths.  I have tested a build with
`--enable-dynamic-executable`, and it works, but
further testing may be needed.

The universal markup converter

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can convert from

It can convert to

Pandoc can also produce PDF output via LaTeX, Groff ms, or HTML.

Pandocs enhanced version of Markdown includes syntax for tables, definition lists, metadata blocks, footnotes, citations, math, and much more. See the Users Manual below under Pandocs Markdown.

Pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document (an abstract syntax tree or AST), and a set of writers, which convert this native representation into a target format. Thus, adding an input or output format requires only adding a reader or writer. Users can also run custom pandoc filters to modify the intermediate AST (see the documentation for filters and Lua filters).

Because pandocs intermediate representation of a document is less expressive than many of the formats it converts between, one should not expect perfect conversions between every format and every other. Pandoc attempts to preserve the structural elements of a document, but not formatting details such as margin size. And some document elements, such as complex tables, may not fit into pandocs simple document model. While conversions from pandocs Markdown to all formats aspire to be perfect, conversions from formats more expressive than pandocs Markdown can be expected to be lossy.
