ialign.el

Emacs package that provides an interactive version of the align-regexp command.

In action: screencast

Additional packages

If you have an optional package - pcre2el - installed, you can use PCRE regexps for alignment.

Usage

To use it, mark a region and then call ialign. You can enter a regexp in the minibuffer that will be passed to align-regexp command. As the contents of minibuffer change, the region is realigned. You can also specify other arguments to align-regexp:

• Increment/decrement spacing (padding) with C-c - and C-c +
• Repeat the alignment throughout the line with C-c C-r.
• Go to next/previous history element with M-n and M-p.
• Toggle tabs with C-c C-t.
• Toggle case sensitivity with C-c M-c.
• Toggle PCRE mode with C-c C-p (requires pcre2el).
• Increment/decrement the parenthesis group which will be modified with C-c [ and C-c ]. Negative parenthesis group means justify (prepend space to each group).
