2017-08-11Added support for translations (localization) (see #3559).John MacFarlane1-46/+212
* readDataFile, readDefaultDataFile, getReferenceDocx, getReferenceODT have been removed from Shared and moved into Class. They are now defined in terms of PandocMonad primitives, rather than being primitve methods of the class. * toLang has been moved from BCP47 to Class. * NoTranslation and CouldNotLoudTranslations have been added to LogMessage. * New module, Text.Pandoc.Translations, exporting Term, Translations, readTranslations. * New functions in Class: translateTerm, setTranslations. Note that nothing is loaded from data files until translateTerm is used; setTranslation just sets the language to be used. * Added two translation data files in data/translations. * LaTeX reader: Support `\setmainlanguage` or `\setdefaultlanguage` (polyglossia) and `\figurename`.
2017-08-10Removed datadir param from readDataFile and getDefaultTemplate.John MacFarlane1-14/+20
In Text.Pandoc.Class and Text.Pandoc.Template, resp. We now get the datadir from CommonState.
2017-08-10Class: add setUserDataDir and getUserDataDir.John MacFarlane1-5/+21
* Add stUserDataDir to CommonState. * Rename stUserDataDir/stCabalDataDir in PureState to stUserDataFiles/stCabalDataFiles.
2017-08-10Expose getDefaultDataFile in both Shared and Class.John MacFarlane1-3/+13
2017-07-30Class: more haddocks.John MacFarlane1-0/+12
2017-07-30Class: Removed unnecessary withMedia, improved haddocks.John MacFarlane1-7/+22
2017-07-19Class: started adding haddocks.John MacFarlane1-10/+39
2017-07-15Don't rely on listDirectory, which is only in newer versions...John MacFarlane1-2/+5
of directory.
2017-07-14Class: make addToFileTree handle directories recursively.John MacFarlane1-6/+15
2017-07-14Class: remove stFontFiles in PureState, 'glob' searches stFiles.John MacFarlane1-4/+2
2017-07-14Class: added addToFileTreeJohn MacFarlane1-0/+8
2017-06-19Tracing: give less misleading line information with parseWithString.John MacFarlane1-2/+7
Previously positions would be reported past the end of the chunk. We now reset the source position within the chunk and report positions "in chunk."
2017-06-19Separated tracing from logging.John MacFarlane1-5/+22
Formerly tracing was just log messages with a DEBUG log level. We now make these things independent. Tracing can be turned on or off in PandocMonad using `setTrace`; it is independent of logging. * Removed `DEBUG` from `Verbosity`. * Removed `ParserTrace` from `LogMessage`. * Added `trace`, `setTrace` to `PandocMonad`.
2017-06-17Use Control.Monad.State.Strict throughout.John MacFarlane1-1/+1
This gives 20-30% speedup and reduction of memory usage in most of the writers.
2017-06-12Changed "extracting..." warning to a regular log message.John MacFarlane1-4/+19
This makes it sensitive to proper verbosity settings. (It is now treated as INFO rather than WARNING, so one doesn't get these messages for creation of tmp images while making a pdf.) API changes: * Removed extractMediaBag from Text.Pandoc.MediaBag. * Added Extracting as constructor for LogMessage.
2017-06-02hlint suggestions.John MacFarlane1-1/+1
2017-06-01Some hlint refactoring.John MacFarlane1-16/+13
2017-06-01Trivial reformatting.John MacFarlane1-3/+7
2017-05-18Don't double extract images from docx.John MacFarlane1-9/+14
This fixes a regression that was introduced when `--extract-media` was generalized to work with any input format. We were getting two versions of each image extracted from a docx, one with a hash, one with the original filename, though only the hash one was used. This patch restores the original behavior (using the original filename). Pointed out in comments on #3674. Thanks to @laperouse.
2017-05-07Rename fillMedia -> fillMediaBag.John MacFarlane1-3/+3
2017-05-07Moved fillMedia, extractMedia from App to Class.John MacFarlane1-3/+53
Also generalized type of fillMedia to any instance of PandocMonad.
2017-05-07Added PandocHttpException, trap exceptions in fetching from URLs.John MacFarlane1-1/+4
Closes #3646.
2017-05-02Added PandocResourceNotFound error.John MacFarlane1-8/+4
Use this instead of PandocIOError when a resource is not found in path. This improves the error message in this case, see #3629.
2017-03-09Changed display format for messages.John MacFarlane1-8/+8
2017-03-04Add hanging indent to log messages.John MacFarlane1-3/+12
This makes them easier to read.
2017-02-24Shared: remove 'warn'.John MacFarlane1-4/+1
PDF writer: Use 'report' instead of 'warn', make it sensitive to verbosity settings.
2017-02-24Class: Add stResourcePath to CommonState, getResourcePath, setResourcePath.John MacFarlane1-8/+32
To be used in implementing `\graphicspath` in LaTeX, and possibly in things like PDF production via context. Use resource path in fetchItem. Issue an info message if we get a resource from somewhere other than ".". Added UsingResourceFrom to log message.
2017-02-23Restore "Fetching..." message with openURL if --verbose.John MacFarlane1-1/+3
2017-02-23Use PandocIOError in Class.John MacFarlane1-36/+23
2017-02-11Class.report: Save all log messages in state.John MacFarlane1-2/+2
Verbosity level only affects which are printed to stdout. (Exception: DEBUG messages are only printed, never saved to state.)
2017-02-11Use new warnings throughout the code base.John MacFarlane1-32/+21
2017-02-10Added Text.Pandoc.Logging (exported module).John MacFarlane1-2/+2
This now contains the Verbosity definition previously in Options, as well as a new LogMessage datatype that will eventually be used instead of raw strings for warnings. This will enable us, among other things, to provide machine-readable warnings if desired. See #3392.
2017-02-09LaTeX reader: Issue warnings when skipping unknown latex commands.John MacFarlane1-1/+1
See #3392.
2017-02-09Reverted deferred media bag code.John MacFarlane1-51/+6
This was not actually being used. Since it adds considerable complexity, it's best not to include it unless we are actually going to use it. The original thought was that we could do all loading in the readers, always deferred and thus costless. This was supposed to eliminate the need to traverse trees loading resources in the docx, epub, odt writers and in PDF and SelfContained. (It would also have the side effect that --extract-media could be used with all input formats. This wasn't an intended side effect, and it could be debated whether it's desirable, since --extract-media was originally designed to extract the media contained in a docx or odt or epub container.) However, we never actually took the step of moving all of this work to the readers, for a couple of reasons. The main reason is that we'd still need to fetch resources in the docx, epub, odt, pdf and self-contained writers, since the Pandoc AST might have been built programatically and hence not generated by a reader. So it's not clear that doing lazy loading in the readers would have any real advantage. I'm still not completely sure about this --- if we change our minds it would be easy to undo this commit. @jkr comments welcome.
2017-02-07Refactored some files formerly in LaTeX reader.John MacFarlane1-4/+4
* Export readFileFromDirs from Class. * Export insertIncludedFile from Parsing. Simplified code in LaTeX/RST readers.
2017-02-07Moved readFileFromDirs to Text.Pandoc.Class.John MacFarlane1-0/+10
This can be used in several different modules, not just LaTeX reader.
2017-01-27Expose FileTree in ClassJohn MacFarlane1-0/+1
2017-01-25Fixed small mistake in instance for logOutput.John MacFarlane1-1/+1
2017-01-25More logging-related changes.John MacFarlane1-23/+22
Class: * Removed getWarnings, withWarningsToStderr * Added report * Added logOutput to PandocMonad * Make logOutput streaming in PandocIO monad * Properly reverse getLog output Readers: * Replaced use of trace with report DEBUG. TWiki Reader: Put everything inside PandocMonad m. API changes.
2017-01-25Class: Changes around logging.John MacFarlane1-27/+45
* Export getLog, setVerbosity * Add report to PandocMonad methods. * Redefine warning and getWarnings in terms of getLog and report. * Remove stWarnings from CommonState, add stLog and stVerbosity.
2017-01-25Class: Warn instead or erroring if we can't fetch mediaJesse Rosenthal1-5/+18
If deferred media can't be fetched, we catch the error and warn instead. We add an internal function for fetching which returns a Maybe value, and then run catMaybes to only keep the Just's.
2017-01-25Class: Refactor fetchItem.Jesse Rosenthal1-38/+44
Move the downloading/reading-in logic out of fetchItem, so we can use it to fill the MediaBag. Now when other modules use `fetchItem` it will fill the MediaBag as expected.
2017-01-25Class: Add insertDeferredMedia function.Jesse Rosenthal1-0/+7
2017-01-25Integrate DeferredMediaBag into CommonStateJesse Rosenthal1-10/+17
The DeferredMediaBag is now the object that is held in state. It should not be visible to users, who will still deal with MediaBag through exported getters and setters. We now have a function `fetchDeferredMedia` which returns () but downloads/reads in all of the deferred media. Note that getMediaBag first fetches all deferred media.
2017-01-25Introduce DeferredMediaBag.Jesse Rosenthal1-0/+24
This is a lazy MediaBag, that will only be evaluated (downloaded/read in) upon demand. Note that we use fetchItem in getDefferedMedia at the moment to read in/download. This means that we don't need to distinguish between URIs and FilePaths. But there is an inefficiency here: `fetchItem` will pull an item out of the mediaBag if it's already there, and then we'll reinsert it. We could separate out `fetchItem` into the function that checks the MediaBag and the underlying downloader/read-inner.
2017-01-25Class: have pure instance of openURL throw an error, for now.John MacFarlane1-1/+1
Later we may want to include a map of URLs and mime type, bytestring pairs in pure state to serve as a fake internet.
2017-01-25Add openURL and readFileStrict to PandocMonad.John MacFarlane1-38/+98
Removed fetchItem and fetchItem'. Provide fetchItem in PandocMonad (it uses openURL and readFileStrict). TODO: - PandocPure instance for openURL. - Fix places where fetchItem is used so that we trap the exception instead of checking for a Left value. (At least in the places where we want a warning rather than a failure.)
2017-01-25Class: Removed getDefaultReferenceDocx/ODT from PandocMonad.John MacFarlane1-22/+2
We don't need these, since the default docx and odt can be retrieved using `readDataFile datadir "reference.docx"` (or odt).
2017-01-25Removed commented-out vestigaes of fail in Class.John MacFarlane1-8/+0
2017-01-25Class: removed 'fail' from PandocMonad.John MacFarlane1-12/+12
Do we need this? I don't see why. There's a name clash which would better be avoided.
