1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)


2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade poshdynargs -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade poshdynargs -y --source="'INTERNAL REPO URL'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)

Description

posh-dynargs

A PowerShell module that enables dynamic tab completion for project-specific commands.

posh-dynargs enables tab completion for commands whose arguments change depending on the current directory. It also generates helper functions for those commands, adding capabilities such as logging, timing, and audio alerts.


src\en-US\about_posh-dynargs.help.txt
TOPIC
    posh-dynargs

SHORT DESCRIPTION
    posh-dynargs enables tab completion for commands whose arguments change
    depending on the current directory. It also generates helper functions for
    those commands, adding capabilities such as logging, timing, and audio
    alerts.

LONG DESCRIPTION
    Many projects rely on commands like build, ci, make, test, etc. Each of
    these commands has its own set of possible arguments, often dozens of them,
    and their usage and interface can vary between projects and certainly
    between organizations.

    posh-dynargs makes tab completion possible for these disparate commands.
    Possible arguments are determined on the fly, so even when arguments change
    or new ones are added, they are instantly tab completable.
    See TAB COMPLETION.

    Additionally, a helper function of the same name is generated for each
    command. Apart from making it possible to invoke the command without the
    leading .\ or ./, it enables additional features such as logging the output.
    See HELPER FUNCTIONS.

    A project that wants to use posh-dynargs only has to include a file called
    .argument-completer-registry.json at the root of the project. This file is
    a registry that describes the completable commands, how to find their
    arguments, and how to customize the helper functions.
    See ARGUMENT COMPLETER REGISTRY.

TAB COMPLETION
    To enable tab completion for a project-specific command, add it to the
    argument completer registry, including a few hints regarding where to find
    and parse the arguments to be completed.

    KNOWN SCRIPT TYPES
    posh-dynargs knows how to extract arguments from Cake scripts, PSake
    scripts, and Make files. In those cases, you only have to register the
    location and type of the script. posh-dynargs figures out the rest.

    For a Cake script, for example, the registry entry might look like this:
    {
        "name": "build",
        "argsPath": "./build/ci.cake",
        "type": "cake",
        "funcDefaults": {
            "logOutput": true,
            "talk": true,
        }
    }

    This entry tells posh-dynargs that the command to invoke is "build", and
    it is dealing with a Cake script that lives at ./build/ci.cake. It will
    parse the script for possible arguments the second you enter build{TAB}. On
    a reasonably performant computer, this is nearly instantaneous.

    CUSTOM SCRIPTS
    You likely have other scripts that posh-dynargs doesn't know how to parse.
    In such a case, register it as a custom command and provide a regex to guide
    posh-dynargs to the correct arguments.

    Here's a sample registry entry for a custom command called "scrape":
    {
        "name": "scrape",
        "argsPath": "./tools/scrape.ps1",
        "type": "custom",
        "regex": "^Task ([A-Z][^ ]+)"
    },

    BINARY COMMANDS
    What about binary commands that aren't parsable? Those commands typically
    ship with a switch like --help from which we can extract the arguments to
    complete. posh-dynargs can execute this help command and cache the help
    text to make future tab completion faster (and safer).

    Sample registry entry for an unparsable binary command:
    {
        "name": "test",
        "helpCommand": "--help",
        "type": "custom",
        "regex": "(--[a-z]+=?)"
    }

    DANGER, WILL ROBINSON
    Executing the "help command" adds a security risk to posh-dynargs, because
    we leave the relative safety of simply parsing text and begin executing
    code. The following precautions have been taken to help mitigate this risk:

    * Only allow executing the registered command
    * Only allow executing a whitelisted set of help arguments:
       * help
       * --help
       * -h
       * --list
       * -l
       * /?
       * -?
    * Additionally, before executing the command, the user is prompted with a
    frightening message, to which they must respond "yes", or the expression
    will not be executed:

        >>> DANGER! OK to run `./test --help`? (yes/no) :

    So where do we add these argument completer registry entries? You will
    create a file at the root of your project called
    .argument-completer-registry.json. See ARGUMENT COMPLETER REGISTRY.

    LEADING DASH POWERSHELL BUG
    As of January, 2019, there is a PowerShell bug that prevents arguments with
    a leading dash from being completed. E.g. "build -stuff" would fail. The
    workaround used by posh-dynargs is to preface those arguments with a
    leading colon ":". Rather than running "build -stuff", you would run
    "build :-stuff". The helper function then strips off the leading colon.
    This is undesirable. Hopefully the bug will be fixed soon.

    ISSUE: https://github.com/PowerShell/PowerShell-Docs/issues/1979

HELPER FUNCTIONS
    A helper function of the same name is generated for for each command. Apart
    from making it possible to invoke the command without the leading .\ or ./,
    it enables the following additional features:

    * Logging of command output.
    * An audible prompt when the command finishes.
       Great for long-running commands.
    * Timing the command.

    Each of these features is optional and configurable in the argument
    completer registry, using options supplied to funcDefaults.
    See ARGUMENT COMPLETER REGISTRY for the full syntax.

ARGUMENT COMPLETER REGISTRY
    The argument completer file is called .argument-completer-registry.json and
    should be placed at the root of the project.

    This JSON file is a registry of the project's completable commands. It
    controls how each command's arguments are discovered. It also configures
    options for the generated helper functions.

    SAMPLE .argument-completer-registry.json
    {
        "completableCommands": [
            {
                "name": "build",
                "argsPath": "./build/ci.cake",
                "type": "cake",
                "funcDefaults": {
                    "logOutput": true,
                    "talk": true,
                    "useTimer": true,
                    "useGlobal": false,
                }
            },
            {
                "name": "scrape",
                "argsPath": "./tools/scrape.ps1",
                "type": "custom",
                "regex": "^Task ([A-Z][^ ]+)"
            },
            {
                "name": "test",
                "helpCommand": "--help",
                "type": "custom",
                "regex": "(--[a-z]+=?)"
            }
        ]
    }

    DESCRIPTION OF ATTRIBUTES

    name:        The name of the command to be completed.

    argsPath:    The path to the script containing the arguments to be parsed.

    helpCommand: For compiled tools. Parse the arguments from the tool's help
                 output. Supply something like "--help" or "-h".
                 The help text output will be cached in $env:TEMP.

    type:        The type of script being parsed. Natively-supported types are
                 "cake", "make", and "psake".

    regex:       (For custom types) The regular expression used to extract the
                 task names from "argsPath" or the output of "helpCommand".
                 The first capturing group must contain the task name.

    funcDefaults:  Sets defaults for the generated helper function.

        logOutput: true or false. If true, log command output to the TEMP
                   directory. Note that you will lose color output.

        talk:      true or false. If true, audibly communicate a failed or
                   successful command invocation.

        useTimer:  true or false. If true, display elapsed time when the
                   command finishes.

        useGlobal: true or false. If true, invoke the command found in your
                   PATH rather than the local directory.

    DISCUSSION
    In the above file sample we can assume that there is an executable .\build,
    a .\scrape, and a .\test in the same directory alongside
    .argument-completer-registry.json. This simple registry tells the argument
    completer where the actual script is located and how to parse it.

    For example, the "build" command above will execute the Cake script located
    in ./build/ci.cake. The "type" is listed as "cake". The argument completer
    knows how to parse Cake files and extract the arguments, which are then
    used for tab completion.

    When you are in this directory and you type build, PowerShell will find the
    registered argument completer and invoke the associated script block. The
    script block will load ./.argument-completer-registry.json and find the
    "build" command. Then it parses the Cake script using the path provided in
    the .json file, and uses that to provide tab completion. This happens every
    time you run the build command, but it happens extremely fast. There is
    typically no lag.

USAGE
    You need to import the posh-dynargs module into your PowerShell session to
    use it. This is done with the command "Import-Module posh-dynargs". Once
    imported, run "Add-PoshDynargsToProfile" so that posh-dynargs is imported
    every time PowerShell starts.

PERFORMANCE
    posh-dynargs piggybacks on top of the PowerShell prompt. Every time prompt
    is invoked, Register-LocalArgumentCompleters is also invoked.

    Register-LocalArgumentCompleters will process .argument-completer-registry.json
    if it exists. This involves registering each argument completer and creating
    a helper function. If you experience a slowdown, it will be here. Once
    registered, the process will not repeat until the directory changes.

    To enable timing of the Register-LocalArgumentCompleters function, set
    $PoshDynargsSettings.EnableTiming = $true

UNDER THE HOOD
    As noted in PERFORMANCE, posh-dynargs works by attaching itself to
    PowerShell's prompt function. Every time the prompt function is invoked,
    a so is the main posh-dynargs function.

    How does this work?
    (I'm not happy with the current implementation, and it's likely to change.)
    If you're using posh-git, the function is attached to and executed with
    $GitPromptSettings.DefaultPromptPrefix. If you aren't using posh-git, the prompt is replaced with a custom one
    which just so happens to run Register-LocalArgumentCompleters.

.SYNOPSIS
    Configures your PowerShell profile (startup) script to import the posh-dynargs
    module when PowerShell starts.
.DESCRIPTION
    Checks if your PowerShell profile script is not already importing posh-dynargs
    and if not, adds a command to import the posh-dynargs module. This will cause
    PowerShell to load posh-dynargs whenever PowerShell starts.
.PARAMETER AllHosts
    By default, this command modifies the CurrentUserCurrentHost profile
    script.  By specifying the AllHosts switch, the command updates the
    CurrentUserAllHosts profile (or AllUsersAllHosts, given -AllUsers).
.PARAMETER AllUsers
    By default, this command modifies the CurrentUserCurrentHost profile
    script.  By specifying the AllUsers switch, the command updates the
    AllUsersCurrentHost profile (or AllUsersAllHosts, given -AllHosts).
    Requires elevated permissions.
.PARAMETER Force
    Do not check if the specified profile script is already importing
    posh-dynargs. Just add Import-Module posh-dynargs command.
.EXAMPLE
    PS C:\> Add-PoshDynargsToProfile
    Updates your profile script for the current PowerShell host to import the
    posh-dynargs module when the current PowerShell host starts.
.EXAMPLE
    PS C:\> Add-PoshDynargsToProfile -AllHosts
    Updates your profile script for all PowerShell hosts to import the posh-dynargs
    module whenever any PowerShell host starts.
.INPUTS
    None.
.OUTPUTS
    None.
