• Commentary

The simplest way to make hide-lines work is to add the following lines to your .emacs file:

=(autoload 'hide-lines "hide-lines" "Hide lines based on a regexp" t) (global-set-key "\C-ch" 'hide-lines)=

Now, when you type C-c h, you will be prompted for a regexp (regular expression). All lines matching this regexp will be hidden in the buffer.

Alternatively, you can type C-u C-c h (ie. provide a prefix argument to the hide-lines command) to hide all lines that do not match the specified regexp.

If you want to make all of the hidden areas re-appear again, type: M-x hide-lines-show-all Or you can bind show-all-invisible to a key and use that to show all the hidden areas again.

If you prefer the opposite behaviour either use =hide-lines-not-matching= or set =hide-lines-reverse-prefix= to t.

=hide-lines= is useful in the Messages buffer or Packages buffer (M-x list-packages). In the Packages buffer the following regular expression can be used to limit the display to all packages marked for installation/uninstallation

• Installation Put hide-lines.el in a directory in your load-path, e.g. ~/.emacs.d/ You can add a directory to your load-path with the following line in ~/.emacs (add-to-list 'load-path (expand-file-name "~/elisp")) where ~/elisp is the directory you want to add (you don't need to do this for ~/.emacs.d - it's added by default).

Add the following to your ~/.emacs startup file.

(require 'hide-lines)

• Commands & keybindings

Below is a complete list of commands:

• hide-lines : Hide lines matching the specified regexp.\ Keybinding: =M-x hide-lines=
• hide-lines-not-matching : Hide lines that don't match the specified regexp.\ Keybinding: =M-x hide-lines-not-matching=
• hide-lines-matching : Hide lines matching the specified regexp.\ Keybinding: =M-x hide-lines-matching=
• hide-lines-show-all : Show all areas hidden by the filter-buffer command.\ Keybinding: =M-x hide-lines-show-all=
• hide-blocks-not-matching Hide text that is not between lines matching START-TEXT and END-TEXT. Keybinding: =M-x hide-blocks-not-matching=
• hide-blocks-matching Hide text that is between lines matching START-TEXT and END-TEXT. Keybinding: =M-x hide-blocks-matching=
• hide-lines-kill-hidden Kill or delete all hidden areas. Keybinding =M-x hide-lines-kill-hidden=

• Customizable Options

Below is a list of customizable options:

• hide-lines-reverse-prefix : If non-nil then - hide-lines : will call - hide-lines-matching : by default, and - hide-lines-not-matching : with a single prefix.\ default value: =nil=
