18.20 Filesets
If you regularly edit a certain group of files, you can define them
as a fileset. This lets you perform certain operations, such as
visiting, query-replace
, and shell commands on all the files at
once. To make use of filesets, you must first add the expression
(filesets-init)
to your init file (see Init File). This
adds a ‘Filesets
’ sub-menu to the menu bar’s ‘File
’ menu.
The simplest way to define a fileset is by adding files to it one at
a time. To add a file to fileset name
, visit the file and type
M-x filesets-add-buffer RET name
RET. If
there is no fileset name
, this creates a new one, which
initially contains only the current file. The command M-x
filesets-remove-buffer removes the current file from a fileset.
You can also edit the list of filesets directly, with M-x
filesets-edit (or by choosing ‘Edit Filesets
’ from the
‘Filesets
’ menu). The editing is performed in a Customize buffer
(see Easy Customization). Normally, a fileset is a simple list of
files, but you can also define a fileset as a regular expression
matching file names. Some examples of these more complicated filesets
are shown in the Customize buffer. Remember to select ‘Save for future sessions
’ if you want to use the same filesets in future Emacs
sessions.
You can use the command M-x filesets-open to visit all the
files in a fileset, and M-x filesets-close to close them. Use
M-x filesets-run-cmd to run a shell command on all the files in
a fileset. These commands are also available from the ‘Filesets
’
menu, where each existing fileset is represented by a submenu.
See Version Control, for a different concept of filesets: groups of files bundled together for version control operations. Filesets of that type are unnamed, and do not persist across Emacs sessions.
