<# .SYNOPSIS Generates PSSVG .DESCRIPTION Generates PSSVG, a module for creating svg images with PowerShell. PSSVG allows you to create Scalable Vector Graphics using PowerShell commands. To make these commands, we will read the Markdown source for the Mozilla Developer Network's documentation on SVG. .NOTES This script should build several scripts, each of which correlate to a given element. Deprecated elements will be skipped. Most elements have a partial list of attributes followed by a series of common attribute groups. As such, we have to do a few fairly complex things here: 1. Get the list of all elements 2. Get the list of all attributes (and all of their metadata) 3. Get the defined attribute groups 4. Parse the documentation for each element 5. Expand out the grouped attributes defined for each element 6. Take the combined content and generate a function This script uses Irregular to assist in the first several steps. It then uses PipeScript to create the final function. .LINK https://github.com/mdn/content/blob/main/LICENSE.md #> foreach ($moduleRequirement in 'Irregular','PipeScript','PSDevOps','ugit') { $requireLatest = $false $ModuleLoader = $null # If the module requirement was a string if ($moduleRequirement -is [string]) { # see if it's already loaded $foundModuleRequirement = Get-Module $moduleRequirement if (-not $foundModuleRequirement) { # If it wasn't, $foundModuleRequirement = try { # try loading it Import-Module -Name $moduleRequirement -PassThru -Global -ErrorAction SilentlyContinue } catch { $null } } # If we found a version but require the latest version, if ($foundModuleRequirement -and $requireLatest) { # then find if there is a more recent version.
