This plugin wraps selected text or, if no text is selected, the current line to the column width specified in the editor's "Right Margin (columns)" setting.
This is a replacement for the Fill Paragraph command, which doesn't work for me.
You can install this plugin directly from an Intellij editor (like Intellij Ultimate, PyCharm, etc.) inside the Preferences -> Plugins -> Browse repositories... window.
To install the plugin from GitHub, download the latest release from https://github.com/abrookins/WrapToColumn/releases, unzip it, open your Intellij editor of choice, go to the Preferences window -> Plugins -> Install plugin from disk, then choose the WrapToColumn.jar file that you unzipped.
The default keyboard shortcut is Command+Control+Shift+W. Feel free to change that beast in your keymap.
By default, this plugin uses your configured global or language-specific right margin setting as the column width to wrap at. However, you may provide a column width that will override both of these settings.
This setting exists in Settings (Preferences on OS X) -> Tools -> Wrap to Column.
The setting is named "Column width override" and accepts an integer value.
By default, text is wrapped using a greedy line-breaking algorithm. This can result in some lines having more whitespace than others.
You can turn on an alternative "minimum raggedness" algorithm in Settings -> Tools -> Wrap to Column. When this setting is on, the plugin will reconfigure text in a paragraph to produce the least amount of whitespace possible. Try it and see if you like it!
Any lines that contain tabs (or are prefixed with tabs as an indent) will be reflowed as if the tabs were characters spaced at your configured tab width.
This means that the text will look right to you if your tab width is 4, but not to your co-maintainer whose tab width is 8. This seems to be the best trade-off.
A menu item for the plugin exists in the Edit drop-down menu: Edit -> Wrap to Column
This plugin reflows selected text by assuming that each character takes one column's worth of space (except tabs, which are expanded to your tab width).
This works fine with monospaced fonts. However, if you use a variable-width font, which seems to be common for some languages like Chinese (see issue #11), then the individual glyphs of the font take up more than one column.
The plugin will still wrap your text to e.g. 80 characters wide, but the position won't match Intellij's right margin guide.
Annnyway, I recommend that you use a monospaced font if you can.
