You can manually enable it on a file by setting the Subversion properties of that file. Keyword substitution happens only in those files where you have specifically enabled it using the svn:keywords property. There are some other things you’ll need to do to allow keyword expansion to occur, however, as I’ll explain in the recipes of this section. When you update, keywords are updated because of other people’s changes. When you commit, the keywords are updated because of your changes. Note that keywords do not update based on repository activity rather they update based on your activity, because keyword expansion is a client-side operation. Same as Id except the URL is not abbreviated. URL to latest version of the file in the repository.Ībbreviated combination of other 4 keywords date in UTC time. You can use either the main keyword or its alias interchangeably in a keyword anchor.ĭate of last known commit date in local time. The table displays the available keywords, some of which have aliases. To use keywords in a file you insert a keyword anchor, which is simply a keyword sandwiched between two dollar signs, e.g. Left to human authors, the information would inevitably grow stale.” Because this information changes each time the file changes, and more importantly, just after the file changes, it is a hassle for any process except the version control system to keep the data completely up to date. Keywords generally provide information about the last modification made to the file. “Subversion has the ability to substitute keywords-pieces of useful, dynamic information about a versioned file-into the contents of the file itself. The Keyword Substitutions section in the Subversion book introduces keywords succinctly: Subversion lets you embed and automatically update these identifying pieces of information within each file you choose with the use of keywords. So now all you need is an easy way to identify the who, what, and when of the files you are examining. which files you want to examine) and you know when (both by date and by revision number by cross-referencing the release M.N tag with revision history). You believe that this defect showed up only in the last month and seems tied to the minor release that was the result of adding features X and Y worked on by developers A, B, and C. Say you are trying to track down a defect and need to review a collection of files as you probe the system, test hypotheses, and follow your hunches. Reminder: Refer to the Subversion book and the TortoiseSVN book for further reading as needed, and as directed in the recipes below. This installment examines the less well-known but extremely handy world of embedded version information. Part 4: Sharing source-controlled libraries in other source-controlled projects.
