Compare Versions

Compare an arbitrary version to the current open version. Use the command Clearcase: Compare with version and choose the version. It uses the integrate vscode diff viewer.

View Private Files

To show view private files in the source control view, there are two configuration parameters

• clearcase.showViewPrivateFiles - to activate the feature
• clearcase.findViewPrivateCommandArguments - the command and its arguments to find view private files
• viewPrivateFileSuffixes - filter the files by regex. The default (hh|cpp|def|c|h|txt)$ can be a good start.

Depending on the view type, snapshot or dynamic, there are different commands.

Snapshot

• cleartool ls -view_only -rec $CLEARCASE_AVOBS

The $CLEARCASE_AVOBS variable can be replaced by a list of vobs separated by a space

Dynamic

• cleartool lsprivate -short

As a default, this extension is preconfigured for snapshot views.

Hijacked Files

To show hijacked files the following configuration properties exist:

• clearcase.showHijackedFiles - to activate the feature
• clearcase.findHijackedCommandArguments - the command and its arguments to find hijacked files

The command can be as follows:

• cleartool ls /vob1 /vob2

Here it is also possible to use the $CLEARTOOL_AVOBS environment variable. But for the sake of performance it is recommended to limit that search.

Remote Cleartool Client

It is possible to use the remote cleartool client with VSCode. To activate, set the configuration vscode-clearcase.remoteCleartool.enable to true. With that set, insert the username to vscode-clearcase.remoteCleartool.webviewUsername. When connecting to the server, the password will be requested. It is stored as long as the VSCode window lives. Alternatively there is a setting for storing the password in the configuration vscode-clearcase.remoteCleartool.webviewPassword.

WSL

You can use this extenion in a WSL environment and a windows clearcase installation. Just make sure the configured executeable is the windows one (this is the default). The second important setting is the tempDir value. If you use a windows cleartool binary the temp dir needs to be a windows style path as already set by default. This path needs to be reachable by the windows cleartool executable. Therefor it is not possible to use a wsl linux only path like /tmp/.

If the above settings are correct everything else is handled by the extension transparantly.

If the windows drives are not mounted in the default /mnt/<letter> paths one can use a mapping in the settings

vscode-clearcase.wsl.pathMapping: [
  {
    "host": "c:\\", "wsl": "/mnt/c",
    "host": "d:\\", "wsl": "/external/d"
  }
]

Logging

It is possible to print the output of the internal clearcase commands into the output console. To control the amount of information that is printed there is a configuration date.

vscode-clearcase.logLevel with the Parameter (Trace, Debug, Information, Warning,Error, Critical, None)

Requirements

A valid ClearCase installation within the system's PATH or a valid executable path setup in the extension preferences value.
