**PLEASE NOTE: This project is no longer maintained due to an added [built-in functionality in IntelliJ](https://www.jetbrains.com/help/idea/using-code-editor.html#preview-tab) to preview files, which works quite similar to this plugin.**

# Quick File Preview (IntelliJ plugin)

Compatible with _IDEA  PhpStorm  WebStorm  PyCharm  RubyMine  AppCode  CLion  Gogland  DataGrip  Rider  MPS  Android Studio_

This plugin enables a quick file preview on simple selecting files in Project View - similar to the preview in Sublime or VSCode.

**Features:**

- show preview (open temporary editor) of selected file
- focus editor of selected file if already opened
- settings page to individualize preview behavior
- customize the editor tab representation (title & color)
- **since 1.5.2** keep collapse/expand state in project view if parent node is collapsed (customizable, enabled by default)

**Please note:** If **[Autoscroll to source/Open files with single click](https://www.jetbrains.com/help/idea/navigating-through-the-source-code.html#scroll_to_from_source)** is enabled, the actual editor tab is opened instead of a preview. To make proper use of the preview tab, **this option must be disabled!**

(inspired by https://youtrack.jetbrains.com/issue/IDEA-130918)

## Settings (*defaults*)

### Project View

#### Preview behavior

Defines when the Preview Editor tab should be shown in general.

##### Auto preview on select *(default)*

Whenever the focused file in the Project View changes, a preview is shown or the already existing editor is focused.

##### Manual preview

Whenever the focused file in the Project View changes, the already existing editor is focused. The Preview Editor tab is only shown when pressing \<SPACE>. The preview stays open on further navigation and must also be closed manually.

#### Toggle tree expand/collapse by single click (*enabled*)

Defines the required number of clicks to expand/collapse a node in Project View tree: one click if option is *enabled* (plugin default), two clicks if option is *disabled* (IDE default).

#### Keep expand/collapse state (*enabled*)

If enabled, the expand/collapse states of the folders are kept when a parent folder gets collapsed/expanded.

#### Close preview if no file selected (*enabled*)

Switching the focus in the Project View to an directory or non-displayable element, the preview is closed. Disable to keep the last Preview Editor tab.

Please note: Due to [unwanted side effects](https://github.com/SeeSharpSoft/intellij-file-preview/issues/77), this setting has no effect if **[Always Select Opened File](https://www.jetbrains.com/help/idea/navigating-through-the-source-code.html#scroll_to_from_source)** is enabled.

### Preview Editor Tab

#### Tab title pattern (*<<%s>>*)

Defines how the file name is formatted in the preview tab title, while **%s** represents the filename. Leaving the field blank will show the title like for usual editor tabs. Tab coloring can be used to distinguish.

#### Tab color (*disabled*)

Sets a custom background color for the preview tab.

#### Close preview if other tab is selected (*disabled*)

Switching editor tabs does not close the current Preview Editor tab on default.

#### Convert to default editor tab when editing previewed content (*enabled*)

If activated, the tab becomes a normal editor tab when a change happened during preview, so it will stay open if another file gets selected.

**Please note:** A default editor tab can always be enforced by \<DOUBLE-CLICK> or \<ENTER> on the file in Project View.
