Overpass Turbo Ultra Postpass

Usage

• Highlights all syntax (Overpass QL, Postpass, MapCSS, YAML)
• Links with usable parts into both Turbo (no YAML) and Ultra (no OT settings)
• Has titles
• Collapsible
• Features most syntaxhighlight capabilities
  • Has a copy button
  • Number lines
  • Highlight lines
  • Link to lines

Notes

• Some parts have to be converted yourself
  • Some settings (eg data:sql ) vs type: postpass  ; or you can add both parts, which will be converted to use only the service-appropriate one correctly)
  • Shortcuts (eg bbox vs wsen )
• Single-line view has code preview on hover
  • No copy button
  • Some encoding are wrong

Syntax

loc works the same. endpoint is unified into server for convenience.

Examples

Overpass only

{{OTUP|id=simpleexample|
Overpass=
[out:json][timeout:25];
{{((}}geocodeArea:Iceland{{))}}->.searchArea;
nwr["natural"="glacier"](area.searchArea);
out geom;
}}
[[#simpleexample_B-2|Jump to and highlight line 2 of part B (Overpass/Postpass)]]

Query

[out:json][timeout:25];
{{geocodeArea:Iceland}}->.searchArea;
nwr["natural"="glacier"](area.searchArea);
out geom;

Jump to and highlight line 2 of part B (Overpass/Postpass)
