There are three types of views: client views, branch views, and label views.
- Client views map files in the depot to files in the client workspace
- Branch views map files in the depot to other parts of the depot
- Label views associate groups of files in the depot with a single label.
Each type of view consists of lines that map files from the depot into the appropriate namespace. For client and branch views, the mappings consist of two file specifications. The left side of the mapping refers to the depot namespace, and the right side of the mapping refers to the client workspace or depot namespace. For label views, only the left side (the depot namespace) of the mapping is necessary because the files are automatically associated with the desired label.
- All views construct a one-to-one mapping between files in the depot and the files in the client workspace, branch, or label.
- If more than one mapping line refers to the same file(s), the earlier mappings are overridden.
- Mappings beginning with a hyphen (
-) specifically exclude any files that match that mapping.
- In client views,
mappings beginning with a plus sign (
+) overlay previous mappings. (Overlay mappings do not apply to branch or label views.)
within mappings are provided in the usual
syntax, beginning with
//, followed by the depot name or
workspace name, and followed by the actual file name(s) within the depot
or workspace. (You cannot use revision specifiers in views.)
The order of mappings in a client or branch view is important because a later mapping in a view always overrides an earlier mapping.
For example, in the view defined by the following two mappings:
//depot/... //ws/... //depot/dir/... //ws/dir2/...
the entire depot is mapped to the client workspace, but the file
//depot/dir/file.c is mapped to
//ws/dir2/file.c and overrides the previous mapping.
If the order of the lines in the view is reversed,
//depot/dir/... //ws/dir2/... //depot/... //ws/...
//depot/dir/file.c is mapped to
//ws/dir/file.c because the second mapping overrides by the first mapping.
If a path or file name in a workspace view, branch view, or label view
contains spaces, use quotes (
") to enclose the path:
//depot/v1/... "//ws/version one/..."
To map file and directory names that contain the characters
is, to interpret such characters as components of path and filenames, and
wildcards), expand the characters to their ASCII equivalents :
Client views are used to map files in the depot to files in client workspaces. A client workspace is an area in which users perform their work. Files are synced from the depot to a client workspace, opened for editing, edited, and checked back into the depot.
When files are synced, they are copied from the depot to the locations in the client workspace to which they were mapped. Likewise, when files are submitted back into the depot, the files are copied from the client workspace to their proper locations in the depot.
The following table lists some examples of client views:
Full client workspace mapped to entire depot
Full client workspace mapped to part of depot
Some files in the depot are excluded from the client
workspace with the hyphen (
//depot/dir/... //ws/... -//depot/dir/exclude/... //ws/dir/exclude/...
Some files in the depot are mapped to a different part of the client workspace
//depot/... //ws/... //depot/rel1/... //ws/release1/...
Files in the client workspace are mapped to different names than their depot names.
Portions of filenames in the depot are rearranged in the client workspace
By default, if two lines map to the same place in the workspace, the first line is ignored.
//depot/dir1/... //ws/build/... //depot/dir2/... //ws/build/...
An overlay mapping with the plus (
//depot/dir1/... //ws/build/... +//depot/dir2/... //ws/build/...
|A ditto mapping with the ampersand (&) sign allows "one-to-many" mapping. Files from the depot map to more than one location in the workspace. Note that workspace files on a line that begins with & are read-only.
//depot/shared/include/... //ws/dir1/include/... &//depot/shared/include/... //ws/dir2/include/...
To create a client view, use
client to bring up a screen where you can specify
how files in the depot are mapped to the files in your client
Branching of the source tree allows multiple sets of files to evolve along different paths. The creation of a branch view allows Helix Server to automatically manage the file copying and edit propagation tasks associated with branching.
Branch views map existing areas of the depot (the source files) onto new areas of the depot (the target files). They are defined in a manner similar to that used for defining client views, but rather than mapping files directly into a client workspace, they merely set up mappings within the depot. Because integration can take place in either direction, every line in a branch view must be unambiguous in both directions; overlay mappings are therefore not permitted in branch views.
New code branching off from the main codeline
Rearranging directories in the new release
//depot/main/... //depot/1.1dev/... //depot/main/*.c //depot/1.1dev/src/*.c //depot/main/*.txt //depot/1.1dev/doc/*.txt
To create a branch view, use this syntax:
No files are copied when a branch view is first created. To copy the
files, you must ensure that the newly-created files are included in any
client view intending to use those files. You can do this by adding the
newly-mapped branch of the depot to your current client view and
Label views assign a label to a set of files in the depot. Unlike client views and branch views, a label view does not copy any files; label views are used to limit the set of files that are taggable by a label.
A new release
The source code for the new release
A distribution suitable for clients
//depot/1.1final/bin/... //depot/1.1final/doc/... //depot/1.1final/readme.txt
To create a label, use
and enter the depot side of the view. Because a label is merely a list of
files and revision levels, only the depot side (the left side) of the
view needs to be specified, and overlay mappings are not permitted.
