CP2K Editor

The CP2K editor is fully customized to make writing input files quick and fun.

Presets¶

The right sidebar provides a large number of presets to quickly assemble an input file. It also issues warnings when incompatible options were selected.

The presets do not hold any internal state, they are merely a different representation of the input file. When a preset is selected, it “stamps” its changes into the input file while leaving the remaining file untouched. For transparency the modified lines are highlighted briefly.

When the input file is edited directly then the presets are updated accordingly. If none of the available options matches the input then the preset will enter a neutral/blank state.

Amenities¶

Auto-complete¶

The editor has auto-complete for section names, keyword names, and enum values.

• Press Tab anywhere to start auto-complete.

• Use Up and Down to select an option.

• Accept a selected option with Enter.

• Abort auto-complete with Esc.

Undo / Redo¶

Any change including preset selections can be reverted with the undo button from the toolbar. Likewise, an undo operation can be reverted with the redo button.

Context help¶

Hovering over a section or keywords brings up a popup with the description from the CP2K input reference.

Linter¶

A linter is continuously checking the input file for syntax errors and misspellings. To see the full error message click on the red dots in the left gutter.

Section folding¶

For larger input files one can hide sections by clicking on the small arrows in the left gutter.

Key bindings¶

Job submission¶

Once the input file is complete, it can be readily launched by clicking on the run icon () in the toolbar, which will bring up the job submission dialog.
