t2wml specification file #18

Could it be linked from the readme of the project? It's a little complicated to know which are the supported functions (e.g., to skip rows) if the the spec is not available

bhatiadivij commented 5 years ago

I have pushed a new build. This build supports the following spec: ValueExpressions: value($col/$row), ItemExpressions: item($col/$row), BooleanEquations: value(C/$row) = "Females" and item(A/$row) = "Q9707" -> value($col/$row), BooleanExpressions: value(C/$row) = "Females" and value(A/$row) contains "Buru"

Nesting of these functions is also allowed For Example: value(value(C/$row) = "Females" -> $col/$row)

I have added support for skip_row and skip_column attributes. These attributes take BooleanExpression as value For Example: skip_row: value(A/$row) = "" skip_column: value($col/3) = "2002"

bhatiadivij commented 5 years ago

Region and cell expressions can be defined as a mathematical expression. For example: left: C+1 right: G-1 top: 5+1 bottom: 8+1 value($col+1/$row+1)

Variables are not supported in any of the cell expressions. For example: value($col/$row-n) This expression is not supported

If you add these to the readme then you can close this issue. You can add something like "Supported operations" or something like that.

Closing, we need a user guide.
