We use Pandoc as a backend for a Braille word processor. to support file
types that we don't currently support. We have most of the filter working
for our file type but the lists are not working right I can't seem to get
the nested lists to come out right. I am trying to get the attributes of a
list in a LUA filter to give me the same information I can see when I
output to JSON. Currently I am using an ugly list like this to test with:
Broken list
1. Item 1
2. Item 2
3. Item 3
1. item 7
2. Item 8
a. Item a
b. Item b
i. Item i
ii. Item ii
1. Item I
2. Item ii
3. Item 9
4. Item 10
When I run it in the native json I get :
,Header 3 ("broken-list",[],[]) [Str "Broken",Space,Str "list"]
,OrderedList (1,Decimal,Period)
[[Para [Str "Item",Space,Str "1"]]
,[Para [Str "Item",Space,Str "2"]]
,[Para [Str "Item",Space,Str "3"]]]
,OrderedList (7,Decimal,Period)
[[Para [Str "item",Space,Str "7"]]
,[Para [Str "Item",Space,Str "8"]
,OrderedList (1,LowerAlpha,DefaultDelim)
[[Para [Str "Item",Space,Str "a"]]
,[Para [Str "Item",Space,Str "b"]
,OrderedList (1,LowerRoman,DefaultDelim)
[[Para [Str "Item",Space,Str "i"]]
,[Para [Str "Item",Space,Str "ii"]
,OrderedList (1,Decimal,DefaultDelim)
[[Para [Str "Item",Space,Str "I"]]
,[Para [Str "Item",Space,Str "ii"]]]]]]]]
,[Para [Str "Item",Space,Str "9"]]
,[Para [Str "Item",Space,Str "10"]]]]
I am trying to parse this with LUA with the function:
function OrderedList(items)
local newItems = {}
local listItems = ''
local itemCtr = 1
beginTag = ''
endTag = ''
for _, item in pairs(items) do
if nil ~= item and string.len(item) > 0 then
item = removeTags(item)
-- listItems = listItems .. ''.. itemCtr .. '. ' .. item .. ''
print ('fuck' .. itemCtr .. '. ' .. item)
table.insert(newItems,''.. itemCtr .. '. ' .. item .. '')
itemCtr = itemCtr + 1
end
end
newItems.bullet = true
return BulletList(newItems)
end
I know I can adjust the above LUA if I cna just figure out how to get the
start value, and the style out of the native into the LUA. Can someone
tell me the line of code I need to ge the attributes. I have tried things
like:
items.attributes
items.listAttributes
I even checked the item before I output the json and saw that tthe
attributes are on the main list. I can't seem to get the LUA function to
see the things like starting value and I don't know what I have to do so
that I can parse the levels correctly. All help is welcome. Heck if
someone has something that can take the above docx list and output it as a
text list that is all I need. I can wrap that in our tags. I have been
looking for any examples of LUA filters that make multi level broken lists
into anything and I can not find an example.
Thanks for any help.
