# P4VC command line client for P4V components

P4VC is a command-line client that can send certain P4 command-line commands to P4V without having to open a full P4V instance. For example, some users of the P4 command-line client might find P4VC to be a convenient way to view the Revision Graph, the Stream Graph, and create or update a review for P4 Code Review.

If P4V is not already running on your computer, your first P4VC command launches a P4V instance.

If P4V is already running, your P4VC commands apply to your P4V instance.

## Command Syntax

Command-line help is available:

p4vc -h displays the list of options:

    p4vc [options] command [arg ...]

    Options:
        -h -?           print this message
        -V              print client version
        -c client       set client name (default $P4CLIENT)
        -C charset      set character set (default $P4CHARSET)
        -p port         set server port (default $P4PORT)
        -u user         set user's username (default $P4USER)

p4vc -help displays the list of commands.

You will see more complete help when you invoke the help for a specific command, such as
`p4vc help branch`
but what follows is a summary of the output of

workspacewindow | Launches a WorkspaceWindow for the provided connection. If the window is already opened, it will be brought to the foreground, and the requested selection will be applied. `-s` takes a filepath in local or depot format. The file will be selected in either the workspace or depot browser. `-t` takes a tab label specifying the active tab. The recognized values are: `pending`, `submitted`, `files`, `branches`, `workspaces`, `jobs`, `streams`, `streamgraph`, `labels` and `remotes` `-r` refreshes the running P4V connection workspace defined by p4vc. If more than one instance of P4V is running, `-r` operates on the first one. For example, if you have one instance of P4V running with connections A and B, and you issue a `p4vc workspacewindow -r` for connection B, that one instance is refreshed. However, if you start a second instance of P4V running with connection C, then issue a `p4vc workspacewindow -r` for connection C, p4vc opens a new Connection C on the first instance instead of refreshing the second instance. | p4vc [options] workspacewindow [ -r ] [ -s path ] [ -t tab ]

- Host = localhost Port = 7999
- The first command sent from P4VC launches a background process. If it fails, the connection timeout is 45 seconds
- Submit HTML Actions are available with P4VC. HTML Actions provide a way to customize behavior before or after a Submit action. To develop your own custom HTML Actions, see the Add custom HTML pages to P4V topic in the P4V API for JavaScript Documentation.
