ialign.el

Section titled “ialign.el”

Additional packages

Section titled “Additional packages”

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

Usage

Section titled “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).
