What are the allowed values for the "SourceConvention" option?

[arnoudbuzing]

I have tried "ColumnLine" as a RHS, but that does not seem to work:

In[3]:= Options[CodeParse, SourceConvention]

Out[3]= {"SourceConvention" -> "LineColumn"}

Are there option values here other that "LineColumn" ?

The allowed values are "LineColumn" or "SourceCharacterIndex". I do not see there being more.

"LineColumn" returns Source metadata in {{line1, col1}, {line2, col2}} format:

In[6]:= CodeConcreteParse["a+b", "SourceConvention" -> "LineColumn"]

Out[6]= ContainerNode[String, {InfixNode[
   Plus, {LeafNode[Symbol, "a", <|Source -> {{1, 1}, {1, 2}}|>], 
    LeafNode[Token`Plus, "+", <|Source -> {{1, 2}, {1, 3}}|>], 
    LeafNode[Symbol, 
     "b", <|Source -> {{1, 3}, {1, 4}}|>]}, <|Source -> {{1, 1}, {1, 
       4}}|>]}, <||>]

"SourceCharacterIndex" returns Source metadata in StringTake-spec format:

In[7]:= CodeConcreteParse["a+b", 
 "SourceConvention" -> "SourceCharacterIndex"]

Out[7]= ContainerNode[String, {InfixNode[
   Plus, {LeafNode[Symbol, "a", <|Source -> {1, 1}|>], 
    LeafNode[Token`Plus, "+", <|Source -> {2, 2}|>], 
    LeafNode[Symbol, 
     "b", <|Source -> {3, 3}|>]}, <|Source -> {1, 3}|>]}, <||>]
