Description Usage Arguments Details Examples

These binary operators are used to query and filter oshex objects. They allow to apply grep-like textual queries (e.g. using %eq% or %inc%) and numerical queries (e.g. using %l%, %leq%, etc.) to tags and attributes. See 'Details' below for a description of each operator.

k %leq% v

`k`	A key to query within an osh object.
`v`	A value to quey within an osh object.

Each operator gets a key-value per as its left-right arguments respectively. %eq% and %inc% are used as equality operators, to condition a filter operation on an exact match or on a partial match (i.e. that a the word is included in the result), respectively.

%meq% and %leq% stand for more/less or equal and are capable to condition a filter operation based on the following numerical conditions: '>=', '<='. Similarly, %m% and %l% allow to condition filter operation based on the following numerical conditions: '>', '<'

# A condition to filter all objects that 
# have a 'landuse:highway' key-value pair

landuse %eq% highway

# A condition to filter all object that have a key equals to 
# addr:housenumber and values higher or equal to 30

addr:housenumber %meq% 30

# A condition to filter all objects that have a building key

building %eq% "."
building %inc% .
