CLion provides a temporary editor. You can create a text or a piece of code for search or exploration purposes. CLion suggests two types of temporary files:
- Scratch files
- The scratch files are fully functional, runnable, debuggable, etc. They require a language to be specified and have an extension. The scratch files are created via Ctrl+Shift+Alt+Insert.
- Scratch buffers
- The scratch buffers are only intended for pure editing, and as such they do not require specifying a language and do not have an extension. The scratch buffers belong to
.txttype by default.
This action has no dedicated shortcut, but you can configure one as described in the section Configuring Keyboard Shortcuts.
Buffer files are reused after creating 5 files. So doing, after reuse, the content and language are reset.
