Apparently Cabal sets a `pandoc_datadir` environment variable
so that the data files will be sought in the source directory
rather than in the final destination (where they aren't yet
installed).
So we no longer need to set `--data-dir` in the tests. We just
need to make sure `pandoc_datadir` is set in the environment
when we call the program in the test suite.
This will fix the issue with loading of pandoc.lua when
pandoc is built with `-embed_data_files`, reported in #7163.
Closes#7163.
[API change] This affects `readFile`, `getContents`, `writeFileWith`,
`writeFile`, `putStrWith`, `putStr`, `putStrLnWith`, `putStrLn`.
`hPutStrWith`, `hPutStr`, `hPutStrLnWith`, `hPutStrLn`, `hGetContents`.
This avoids the need to uselessly create a linked list of characters
when emiting output.
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.
* Use concatMap instead of reimplementing it
* Replace an unnecessary multi-way if with a regular if
* Use sortOn instead of sortBy and comparing
* Use guards instead of lots of indents for if and else
* Remove redundant do blocks
* Extract common functions from both branches of maybe
Whenever both the Nothing and the Just branch of maybe do the same
function, do that function on the result of maybe instead.
* Use fmap instead of reimplementing it from maybe
* Use negative forms instead of negating the positive forms
* Use mapMaybe instead of mapping and then using catMaybes
* Use zipWith instead of mapping over the result of zip
* Use unwords instead of reimplementing it
* Use <$ instead of <$> and const
* Replace case of Bool with if and else
* Use find instead of listToMaybe and filter
* Use zipWithM instead of mapM and zip
* Inline lambda wrappers into the real functions
* We get zipWithM from Text.Pandoc.Writers.Shared
* Use maybe instead of fromMaybe and fmap
I'm not sure how this one slipped past me.
* Increase a bit of indentation
PR #5884.
+ Use pandoc-types 1.20 and texmath 0.12.
+ Text is now used instead of String, with a few exceptions.
+ In the MediaBag module, some of the types using Strings
were switched to use FilePath instead (not Text).
+ In the Parsing module, new parsers `manyChar`, `many1Char`,
`manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`,
`mantyUntilChar` have been added: these are like their
unsuffixed counterparts but pack some or all of their output.
+ `glob` in Text.Pandoc.Class still takes String since it seems
to be intended as an interface to Glob, which uses strings.
It seems to be used only once in the package, in the EPUB writer,
so that is not hard to change.
Quite a few modules were missing copyright notices.
This commit adds copyright notices everywhere via haddock module
headers. The old license boilerplate comment is redundant with this and has
been removed.
Update copyright years to 2019.
Closes#4592.
Previously we just tacked on a directory to the command
line, but that didn't work when we e.g. used a pipe for round tripping,
with two invocations of pandoc.
