    <p>I'd like to partly automate creation of GNU-style ChangeLog entries when working with source code in version control. The <code>add-changelog-entry-other-window</code> works with one file at a time and you have to visit the file to use it.</p> <p>What I'd like to see instead is to have some command that would take an output of <code>diff -u -p</code> (or have integration with VC modes so it could process <code>svn diff</code> etc) and to create all the skeleton entries at once.</p> <p>For example, if <code>svn status</code> shows</p> <pre><code>D file1.c M file2.c A file3.c </code></pre> <p>the command would create</p> <pre><code>2009-09-05 My Name &lt;my.email&gt; * file1.c: Removed. * file2.c: WRITE YOUR CHANGES HERE * file3.c: New. </code></pre> <p>Better yet, if it could parse the changed files in some languages to an extent so it could offer:</p> <pre><code> * file2.c (new_function): New function. (deleted_function): Removed. (changed_function): WRITE YOUR CHANGES HERE </code></pre> <p>I have found <a href="http://www.gnu.org/software/emacs/manual/html_node/emacs/Log-Buffer.html" rel="nofollow noreferrer">this feature in Emacs manual</a>, but I don't see how I could apply it here.</p> <p>Any suggestions? Thanks.</p> <p>EDIT: One answer suggested <a href="http://gnu.cict.fr/software/emacs/manual/html_node/emacs/Change-Logs-and-VC.html" rel="nofollow noreferrer">vc-update-change-log</a>. Unfortunately it only supports CVS and it creates ChangeLog entries by querying the already-commited VC logs. Thus even if it supported svn and others, it would be impossible to commit the changes and the ChangeLog in the same commit.</p> <p>EDIT2: Apparently add-changelog-entry-other-window (C-x 4 a) works not only from visited file but from diff hunk involving that file too. (<a href="http://www.emacswiki.org/emacs/ChangeLog" rel="nofollow noreferrer">Source</a>) This is almost what I am looking for. This together with elisp loop to iterate through all hunks should solve it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
