2021-10-22Lua: marshal Attr values as userdataAlbert Krewinkel1-21/+34
- Adds a new `pandoc.AttributeList()` constructor, which creates the associative attribute list that is used as the third component of `Attr` values. Values of this type can often be passed to constructors instead of `Attr` values. - `AttributeList` values can no longer be indexed numerically.
2021-10-22Switch to hslua-2.0Albert Krewinkel1-25/+0
The new HsLua version takes a somewhat different approach to marshalling and unmarshalling, relying less on typeclasses and more on specialized types. This allows for better performance and improved error messages. Furthermore, new abstractions allow to document the code and exposed functions.
2021-02-02Add tests for search_path_separatorAlbert Krewinkel1-0/+8
2021-02-02Check that all documented functions are present.Albert Krewinkel1-0/+19
Rely on tests in the module package to check the correctness of each function.
2021-02-02Lua: add module "pandoc.path"Albert Krewinkel1-0/+17
The module allows to work with file paths in a convenient and platform-independent manner. Closes: #6001 Closes: #6565
2020-09-20Lua filters: add SimpleTable for backwards compatibility (#6575)Albert Krewinkel1-0/+66
A new type `SimpleTable` is made available to Lua filters. It is similar to the `Table` type in pandoc versions before 2.10; conversion functions from and to the new Table type are provided. Old filters using tables now require minimal changes and can use, e.g., if PANDOC_VERSION > {2,10,1} then pandoc.Table = pandoc.SimpleTable end and function Table (tbl) tbl = pandoc.utils.to_simple_table(tbl) … return pandoc.utils.from_simple_table(tbl) end to work with the current pandoc version.
2020-04-17API change: use PandocError for exceptions in Lua subsystemAlbert Krewinkel1-4/+3
The PandocError type is used throughout the Lua subsystem, all Lua functions throw an exception of this type if an error occurs. The `LuaException` type is removed and no longer exported from `Text.Pandoc.Lua`. In its place, a new constructor `PandocLuaError` is added to PandocError.
2020-01-11Lua: add methods `insert`, `remove`, and `sort` to pandoc.ListAlbert Krewinkel1-40/+80
The functions `table.insert`, `table.remove`, and `table.sort` are added to pandoc.List elements. They can be used as methods, e.g. local numbers = pandoc.List {2, 3, 1} numbers:sort() -- numbers is now {1, 2, 3}
2020-01-11pandoc.List.lua: make `pandoc.List` a callable constructorAlbert Krewinkel1-0/+9
It is now possible to construct a new List via `pandoc.List()` instead of `pandoc.List:new()`.

2019-09-15Lua filters: allow passing of HTML-like tables instead of Attr (#5750)Albert Krewinkel1-0/+41
Attr values can now be given as normal Lua tables; this can be used as a convenient alternative to define Attr values, instead of constructing values with `pandoc.Attr`. Identifiers are taken from the *id* field, classes must be given as space separated words in the *class* field. All remaining fields are included as misc attributes. With this change, the following lines now create equal elements: pandoc.Span('test', {id = 'test', class = 'a b', check = 1}) pandoc.Span('test', pandoc.Attr('test', {'a','b'}, {check = 1})) This also works when using the *attr* setter: local span = pandoc.Span 'text' span.attr = {id = 'test', class = 'a b', check = 1} Furthermore, the *attributes* field of AST elements can now be a plain key-value table even when using the `attributes` accessor: local span = pandoc.Span 'test' span.attributes = {check = 1} -- works as expected now Closes: #5744
2019-09-08Replace Element and makeHierarchical with makeSections.John MacFarlane1-8/+5
Text.Pandoc.Shared: + Remove `Element` type [API change] + Remove `makeHierarchicalize` [API change] + Add `makeSections` [API change] + Export `deLink` [API change] Now that we have Divs, we can use them to represent the structure of sections, and we don't need a special Element type. `makeSections` reorganizes a block list, adding Divs with class `section` around sections, and adding numbering if needed. This change also fixes some longstanding issues recognizing section structure when the document contains Divs. Closes #3057, see also #997. All writers have been changed to use `makeSections`. Note that in the process we have reverted the change c1d058aeb1c6a331a2cc22786ffaab17f7118ccd made in response to #5168, which I'm not completely sure was a good idea. Lua modules have also been adjusted accordingly. Existing lua filters that use `hierarchicalize` will need to be rewritten to use `make_sections`.
2019-08-16Lua: traverse nested blocks and inlines in correct orderAlbert Krewinkel1-0/+38
Traversal methods are updated to use the new Walk module such that sequences with nested Inline (or Block) elements are traversed in the order in which they appear in the linearized document. Fixes: #5667
2019-06-12Lua: add a `clone()` method to all AST elements (#5572)Albert Krewinkel1-0/+38
Closes: #5568

2019-06-11Lua pandoc module: better tests for Attr and AttributeListAlbert Krewinkel1-0/+65

2019-05-29Lua Version type: shorten "version too old" messageAlbert Krewinkel1-1/+1
2019-05-29Lua: add Version type to simplify comparisonsAlbert Krewinkel2-0/+112
Version specifiers like `PANDOC_VERSION` and `PANDOC_API_VERSION` are turned into `Version` objects. The objects simplify version-appropriate comparisons while maintaining backward-compatibility. A function `pandoc.types.Version` is added as part of the newly introduced module `pandoc.types`, allowing users to create version objects in scripts.
2019-05-20Improve output of Lua tests (#5499)Albert Krewinkel2-0/+154
This makes use of tasty-lua, a package to write tests in Lua and integrate the results into Tasty output. Test output becomes more informative: individual tests and test groups become visible in test output. Failures are reported with helpful error messages.
