TikZ Editor (tikzc)

WYSIWYG editing of .tikz files (based on tikz-editor) plus SVG / PNG export via lualatex.

• Open a .tikz file and open the TikZ Editor to the side via the icon in the editor's top-right (or Ctrl+K V).
• The panel is canvas-only (you edit code in VSCode's text editor).
• Shape operations on the canvas are written back to VSCode's buffer automatically (save to disk with Ctrl+S). Edits in the text editor are reflected in the canvas instantly.
• Rendering uses tikz-editor's TikZ parser (no LaTeX needed, instant). When you need accurate output, export via lualatex.
• Command palette: TikZ: Export as SVG / TikZ: Export as PNG (lualatex + dvisvgm / pdftoppm).

Export requires a local TeX environment (not bundled with this extension). lualatex (TeX Live etc. with TikZ/PGF and fontspec), dvisvgm, and pdftoppm must be on your PATH. WYSIWYG editing itself works without a TeX environment.

On export, options can be set via #| headers at the top of the source:

#| packages: [circuitikz, pgfplots]
#| libraries: [arrows.meta, calc]
#| scale: 1.5
#| mainfont: IPAexGothic
