Tabdir Redux

This plugin will allow you to have directory names added to tab labels, and use various ways to shorten them, including regex.

This is an updated and extended fork of IntelliJ plugin Tabdir, originally found at crazyproger/Tabdir and IntelliJ Plugin Marketplace here.

You can install this fork of the plugin from the IntelliJ Marketplace here. You will have to uninstall the old version first.

Description

Awesome replacement for IDEA's 'Show directory in editor tabs for non-unique filenames'. This plugin will allow you to have directory names added to tab labels. It can also show only path differences, so if you have blog/controllers/index and news/controllers/index, it will add either [blog] or [news]. You can control how prefixes will be formatted in Settings tab 'Tabdir'.

Tip: If you're having trouble managing dozens of open files, try enabling vertical tabs and 'Sort tabs alphabetically'.

Features

• add file's path to tab title
• shorten the file's path in table title, limit folder name length and number of nested folders
• configure different tab prefixes for any folder
• set empty path prefixes—if the file's path is shortened to an empty string, e.g., the file is at the top level of a folder, you can assign it a custom prefix to keep these files ordered together
• regex replacements for tab titles

Configuration

Per-project configuration allows specifying different formatting rules for each directory in project.

To enable per-project configuration, enable "Use per project configuration" checkbox and reopen the Settings window (needs close with Ok or Apply buttons). After that, you will find 'Tabdir Project Settings' configuration in "Other Settings".

Note: you should turn off IDE Settings → Editor tabs → Show directory in editor tabs for non-unique filenames.

Usage notes

• There is some weirdness around the global configuration, so create at least one Per project configuration and set its Configuration for directory and Always show path relative to to your project's folder.
• If the path ([{0}]) part after the tab title replacement ends up empty, nothing in [] brackets is shown, so use unique Empty path replacement to differentiate the folders. Empty path replacement will be prepended to the filename.
• Use e.g. a space or some special character as Empty path replacement for your project's root folder, that way you can keep all the files in root together.
• Regex title replacements work on full tab title you get after the Tab title format ([{0}] $1 by default, which means [folder] filename). The regex is in java.util.regex format, regexes are newline delimited and :: separated strings of match::replacement.
• You can use any Java's regex syntax tricks, e.g., capture groups in both match and replacement, so running e.g. app/(.*)/routes/(.*)\.ts::foo $1 $2 on app/web/routes/my-route.ts will end up with foo web my-route.
• regex results are chained, the result of a first regex is an input for the second one, and so on, and run top to bottom, so you can run multiple regexes on the same title. As a result, you have to take care about unexpected matches and replacements.
• if the opened file is outside your project, the directory won't be shown unless you configure Tabdir Project Settings and add folder for e.g. the root of the drive the file is in - for example, Configuration for directory: C:\, Always show path relative to: C:\, Tab title format: [C:/{0}] {1}, Reduce dir names: unchecked.
• to show tab title format changes for the already open files, you will either have to reopen the files, or change Tabs placement (Settings -> Editor -> General -> Editor Tabs), from e.g., Left to Top, click Apply, and then set it back to your preference and click Ok (haven't found a better way to update the tab titles yet, sorry).
