This is a basic local-only text editor with a few convenient features for NYC zoning analysis.

Open any plain-text (.txt) file with "Choose File" (this could be a pre-populated template). "Save file" will download a copy with edits.

Any text that looks like a ZR citation ("NN-NNN") appears as a clickable link to that section in the online Zoning Resolution.

The front-matter block at beginning of the file (between "---") can be used to define metadata variables like lot area, frontage etc.

Formulas and basic math enclosed in backticks ("`1 + 1`") can be evaluated and replaced by pressing Ctrl+Enter when the cursor is over that area. You can refer to metadata variables here, and there is a special "numFormat" function to format numbers, optionally with a specified number of decimal places.

Despite clickable links and other custom formatting within the editor, the actual document always stays plain text, so you can easily copy-paste snippets into Excel, Rhino, InDesign or other programs without complication.
