Bash Completion For Synopsys (Black Duck) Detect

Suggests options and parameters to complete Synopsys (Black Duck) Detect commands.

Installation

In all cases, you simply need to install the appropriate bash completion package (if not already installed) and then copy the detect completion script from this repository into the right directory for your system. For example:

sudo apt install bash-completion
sudo sh -c 'curl -sL https://raw.githubusercontent.com/thaljef/synopsys-detect-bash-completion/master/detect > /etc/bash_completion.d/detect'
bash -l; # To start new shell

In some cases, you may need to explicitly load the completion framework into your shell. This is usually done by adding something like source /etc/bash_completion to your ~\.bashrc file.

The actual directory for your bash completion scripts and the exact command to load them into your shell will vary by Linux distro and version. The above is just an example; consult your distro docs for more specific guidance.

Usage

The bash completion mechanism relies on having a named command to bind the completions to. However, it is customary to execute Detect via a remote bootstrapping script. This execution process cannot be used with bash completion.

Therefore, it is necessary to do that bootstrapping in a named command in order to use these completions for Detect. The following must be placed in an executable file named detect and that file should be in a directory that is in your $PATH:

#!/bin/bash

bash <(curl -s -L https://detect.synopsys.com/detect7.sh) $*

Examples

Option names:

$> detect --detect.docker.[TAB][TAB]
--detect.docker.image=                   --detect.docker.inspector.version=    --detect.docker.tar=
--detect.docker.inspector.air.gap.path=  --detect.docker.path.required=
--detect.docker.inspector.path=          --detect.docker.path=

Option parameters:

$> detect --detect.project.tier=[TAB][TAB]
1  2  3  4  5

$> detect --detect.trust.cert=[TAB][TAB]
false  true

Option parameter lists:

$> detect --detect.project.tools=[TAB][TAB]
ALL             BINARY_SCAN     DOCKER          POLARIS
BAZEL           DETECTOR        NONE            SIGNATURE_SCAN

$> detect --detect.project.tools=DOCKER,[TAB][TAB]
DOCKER,BAZEL           DOCKER,DETECTOR        DOCKER,SIGNATURE_SCAN
DOCKER,BINARY_SCAN     DOCKER,POLARIS

Compatibility

This completion script is known to work with bash 4.x or 5.x which is found in any recent Linux distro. It will probably work with recent versions of zsh too. It will probably not work with bash 3.x or older. For Windows, use either Cygwin or the Linux Subsytem for Windows 10 to get a compatible shell. MacOS has an ancient version of bash, so you'll probably need to install homebrew and install both the bash and bash-completion2 brews.

Caveats

• The completions are derived from the documentation for Detect. But the options described in the documentation don't always agree with the implementation. So you may encounter options that are not correctly completed, or completed options that are not supported.

• The Detect bootstrapping optionally uses certain environment variables. Ideally, those same variables should be used here too. But at the moment, they are not. So if you use those variables, it may affect the completions.
