1-- For the moment I put this here as example. When writing the publication modules we 2-- explored several approached: pure tex, pure lua, a mix with xml, etc. In the end 3-- each has advantages and drawbacks so we ended up with readable tex plus helpers in 4-- lua. Anyway here is a lua variant of a setup ... it doesn't look nicer. An alternative 5-- can be to build a table with characters but then we need to pass left, right and 6-- other separators so again no real gain. 7 8-- function publications.maybe.default.journal(currentdataset,currenttag) 9-- if publications.okay(currentdataset,currenttag,"journal") then 10-- context.btxspace() 11-- context.startbtxstyle("italic") 12-- commands.btxflush(currentdataset,currenttag,"expandedjournal -> journal") 13-- context.stopbtxstyle() 14-- if publications.okay(currentdataset,currenttag,"volume") then 15-- context.btxspace() 16-- commands.btxflush(currentdataset,currenttag,"volume") 17-- if publications.okay(currentdataset,currenttag,"number") then 18-- context.ignorespaces() 19-- context.btxleftparenthesis() 20-- commands.btxflush(currentdataset,currenttag,"number") 21-- context.btxrightparenthesis() 22-- end 23-- elseif publications.okay(currentdataset,currenttag,"number") then 24-- context.btxlabeltext("default:number") 25-- context.btxspace() 26-- commands.btxflush(currentdataset,currenttag,"number") 27-- end 28-- if publications.okay(currentdataset,currenttag,"pages") then 29-- context.btxcomma() 30-- commands.btxflush(currentdataset,currenttag,"pages") 31-- end 32-- context.btxcomma() 33-- end 34-- end 35 36return { 37 -- 38 -- metadata 39 -- 40 name = "default", 41 version = "1.00", 42 comment = "DEFAULT specification", 43 author = "Alan Braslau and Hans Hagen", 44 copyright = "ConTeXt development team", 45 -- 46 -- derived (combinations of) fields (all share the same default set) 47 -- 48 virtual = { 49 "authoryear", 50 "authoryears", 51 "authornum", 52 "num", 53 "suffix", 54 }, 55 -- 56 -- special datatypes 57 -- 58 types = { 59 author = "author", -- interpreted as name(s) 60 editor = "author", -- interpreted as name(s) 61 page = "pagenumber", -- number or range: f--t -- maybe just range 62 pages = "pagenumber", -- number or range: f--t -- maybe just range 63 volume = "range", -- number or range: f--t 64 number = "range", -- number or range: f--t 65 keywords = "keyword", -- comma|-|separated list 66 }, 67 -- 68 -- categories with their specific fields 69 -- 70 categories = { 71 -- 72 -- the following fields are for documentation and testing purposes 73 -- 74 ["demo-a"] = { 75 sets = { 76 author = { "author", "institution", "organization" }, 77 }, 78 required = { "author", "title", "year" }, 79 optional = { "subtitle" }, 80 }, 81 ["demo-b"] = { 82 sets = { 83 authors = { "author", "institution", "organization" }, 84 }, 85 required = { "authors", "title", "year" }, 86 optional = { "subtitle" }, 87 }, 88 -- 89 -- we only provide article and book (maybe a few more later) and we keep it 90 -- real simple.
