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.
* Fix hlint suggestions, update hlint.yaml
Most suggestions were redundant brackets. Some required
LambdaCase.
The .hlint.yaml file had a small typo, and didn't ignore camelCase
suggestions in certain modules.
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.
* Require recent doctemplates. It is more flexible and
supports partials.
* Changed type of writerTemplate to Maybe Template instead
of Maybe String.
* Remove code from the LaTeX, Docbook, and JATS writers that looked in
the template for strings to determine whether it is a book or an
article, or whether csquotes is used. This was always kludgy and
unreliable. To use csquotes for LaTeX, set `csquotes` in your
variables or metadata. It is no longer sufficient to put
`\usepackage{csquotes}` in your template or header includes.
To specify a book style, use the `documentclass` variable or
`--top-level-division`.
* Change template code to use new API for doctemplates.
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.
* XML.toEntities: changed type to Text -> Text.
* Shared.tabFilter -- fixed so it strips out CRs as before.
* Modified writers to take Text.
* Updated tests, benchmarks, trypandoc.
[API change]
Closes#3731.
