How To Pass Options / Switches
You can pass options and switches in the following ways:
Unless stated otherwise, an option/switch should only be passed one time. Otherwise you may find weird/non-supported behavior.
-, /, or -- (one character switches should not use --)
Option Bundling / Bundled Options: One character switches can be bundled. e.g. -d (debug), -f (force), -v (verbose), and -y (confirm yes) can be bundled as -dfvy.
NOTE: If debug or verbose are bundled with local options (not the global ones above), some logging may not show up until after the local options are parsed.
Use Equals: You can also include or not include an equals sign = between options and values.
Quote Values: When you need to quote an entire argument, such as when using spaces, please use a combination of double quotes and apostrophes ("'value'"). In cmd.exe you can just use double quotes ("value") but in powershell.exe you should use backticks (`"value`") or apostrophes ('value'). Using the combination allows for both shells to work without issue, except for when the next section applies.
Pass quotes in arguments: When you need to pass quoted values to to something like a native installer, you are in for a world of fun. In cmd.exe you must pass it like this: -ia "/yo=""Spaces spaces""". In PowerShell.exe, you must pass it like this: -ia '/yo=""Spaces spaces""'. No other combination will work. In PowerShell.exe if you are on version v3+, you can try --% before -ia to just pass the args through as is, which means it should not require any special workarounds.
Periods in PowerShell: If you need to pass a period as part of a value or a path, PowerShell doesn’t always handle it well. Please quote those values using “Quote Values” section above.
Options and switches apply to all items passed, so if you are installing multiple packages, and you use --version=1.0.0, choco is going to look for and try to install version 1.0.0 of every package passed. So please split out multiple package calls when wanting to pass specific options.
Scripting / Integration – Best Practices / Style Guide
When writing scripts, such as PowerShell scripts passing options and switches, there are some best practices to follow to ensure that you don’t run into issues later. This also applies to integrations that are calling Chocolatey and parsing output. Chocolatey uses PowerShell, but it is an exe, so it cannot return PowerShell objects.
Following these practices ensures both readability of your scripts AND compatibility across different versions and editions of Chocolatey. Following this guide will ensure your experience is not frustrating based on choco not receiving things you think you are passing to it.
For consistency, always use choco, not choco.exe. Never use shortcut commands like cinst or cup (The shortcuts cinst and cup will be removed in v2.0.0).
Always have the command as the first argument to choco. e.g. choco install, where install is the command.
If there is a subcommand, ensure that is the second argument. e.g. choco source list, where source is the command and list is the subcommand.
Typically the subject comes next. If installing packages, the subject would be the package names, e.g. choco install pkg1 pkg2.
Never use ‘nupkg’ or point directly to a nupkg file UNLESS using ‘choco push’. Use the source folder instead, e.g. choco install <package id> --source="'c:\folder\with\package'" instead of choco install DoNotDoThis.1.0.nupkg or choco install DoNotDoThis --source="'c:\folder\with\package\DoNotDoThis.1.0.nupkg'".
Switches and parameters are called simply options. Options come after the subject. e.g. choco install pkg1 --debug --verbose.
Never use the force option (--force/-f) in scripts (or really otherwise as a default mode of use). Force is an override on Chocolatey behavior. If you are wondering why Chocolatey isn’t doing something like the documentation says it should, it’s likely because you are using force. Stop.
Always use full option name. If the short option is -n, and the full option is --name, use --name. The only acceptable short option for use in scripts is -y. Find option names in help docs online or through choco -? /choco [Command Name] -?.
For scripts that are running automated, always use -y. Do note that even with -y passed, some things / state issues detected will temporarily stop for input – the key here is temporarily. They will continue without requiring any action after the temporary timeout (typically 30 seconds).
Full option names are prepended with two dashes, e.g. -- or --debug --verbose --ignore-proxy.
When setting a value to an option, always put an equals (=) between the name and the setting, e.g. --source="'local'".
When setting a value to an option, always surround the value properly with double quotes bookending apostrophes, e.g. --source="'internal_server'".
If you are building PowerShell scripts, you can most likely just simply use apostrophes surrounding option values, e.g. --source='internal_server'.
Prefer upgrade to install in scripts. You can’t install to a newer version of something, but you can choco upgrade which will do both upgrade or install (unless switched off explicitly).
If you are sharing the script with others, pass --source to be explicit about where the package is coming from. Use full link and not source name (‘https://community.chocolatey.org/api/v2’ versus ‘chocolatey’).
If parsing output, you might want to use --limit-output/-r to get output in a more machine parseable format. NOTE: Not all commands handle return of information in an easily digestible output.
Use exit codes to determine status. Chocolatey exits with 0 when everything worked appropriately and other exits codes like 1 when things error. There are package specific exit codes that are recommended to be used and reboot indicating exit codes as well. To check exit code when using PowerShell, immediately call $exitCode = $LASTEXITCODE to get the value choco exited with.
Here’s an example following bad practices (line breaks added for readability):
Which will allow for the newest version of something installed or upgraded to (which allows for more environmental consistency on packages and versions)?
Which may throw an error on a badly passed option?
Which will throw errors on unknown option values? See explanation below.
Chocolatey ignores options it doesn’t understand, but it can only ignore option values if they are tied to the option with an equals sign (‘=’). Note those last two options in the examples above? If you roll off of a commercial edition or someone with older version attempts to run the badly crafted script --c4b-option 'Yaass' --option-that-is-new 'dude upgrade', they are likely to see errors on ‘Yaass’ and ‘dude upgrade’ because they are not explicitly tied to the option they are written after. Now compare that to the other script. Choco will ignore --c4b-option="'Yaass'" and --option-that-is-new="'dude upgrade'" as a whole when it doesn’t register the options. This means that your script doesn’t error.
Following these scripting best practices will ensure your scripts work everywhere they are used and with newer versions of Chocolatey.
