Grammar: file -> <lines> lines -> <line> | <line><lines> line -> <include> | <section header> | <declaration> | <comment> | <empty> include -> is<comment> section header -> sh<comment> declarations -> sd<comment> comment -> c empty -> e Terminals: is: Include Statement ^#include\s[^\s#]+ sh: Section Header ^\s*\[[^\]]+\] sd: Setting Declaration ^\s*[^\s=#]+\s*(=\s*([^#]|\\#)+|`"[^`"]*`"|'[^']*')? c: Comment (?<![\\])#.* e: Empty line \s* Additional Rules: - The first declaration of the file must be preceeded by a section header. - If more than one value is declared for a setting, they will be collected into an array. - All values will be read as strings and the application using the configuration must determine how to interpret the values. .PARAMETER Path The path to the configuration file. .PARAMETER Content Alternatively content to be parsed can be provided as a string. .PARAMETER Config Pre-populated configuration hashtable. If provided, the parser will add new settings to the hashtable. The default behavior is to generate a new hashtable. .PARAMETER NoInclude Causes the parser skip include statements. .PARAMETER NotStrict Stops the parser from throwing an exceptions when errors are encountered. .PARAMETER Silent Stops the parser from outputting anything to the console. .PARAMETER MetaData Hashtable used to record MetaData while parsing. Presently only records Includes and errors. .PARAMETER Cache Hashtable used to cache the results of each file parsed. Useful to minimize reads from disk when parsing multiple job files using the common includes. .PARAMETER Loud Causes the parser to output extra information to the console. .PARAMETER duplicatesAllowed Names of settings for which duplicate values are allowed. By default, if there are two declarations of the same setting with the same value, the second occurence of the value will be discarded. When a setting name is specified here, the second occurrence will instead be appended to the list of values for the setting. .PARAMETER IncludeRootPath The root path to use when resolving includes. If this value isn't provided then it will default to the directory part of $Path. Include-paths that start with '\' or '/' will use this value when resolving where to look for the included file. Paths that do not start with either '\' or '/' will use the directory of the file currently being processed. If the command is called using the "String" parameter set, then this value will default to $pwd (current working directory). All included files will be parsed using the same IncludeRootPath. .EXAMPLE Normal Read: $conf = Parse-Config "C:\Config.ini" Accumulating information into a configuration hashtable: $conf = Parse-Config "C:\Config2.ini" $config Skipping #include statements: $conf = Parse-Config "C:\Config.ini" -NoInclude Stop the parser from throwing an exception on error (use MetaData object to record errors): $metadata = @{} $conf = Parse-Config "C:\Config.ini" -NotStrict -MetaData $metadata # Echo out the errors: $metadata.Errors | % { Write-Host $_ } .NOTES General notes #> function Parse-ConfigFile { [CmdletBinding(DefaultParameterSetName="File")] param ( [parameter( Mandatory=$true, Position=1, ParameterSetName="File", HelpMessage="Path to the file." )] [String] $Path, # Name of the job-file to parse (including extension) [parameter( Mandatory=$true, Position=1, ParameterSetName="String", HelpMessage="Content to be parsed instead of reading from the file path.

Files may also be included into the template by using <<(<path to file>)>>, if the file is a .ps1 file it will be interpreted as an expression to be executed, otherwise it will be treated as a template file and rendered using the same Values. .PARAMETER templatePath The path to the template file that should be rendered (relative or fully qualified, UNC paths not supported). .PARAMETER values A hashtable of values that should be used when resolving powershell expressions. The keys in this hashtable will introduced as variables into the resolution context. The $values variable itself is available as well. .PARAMETER Cache A hashtable used to cache the results of loading template files. Passing this parameter allows you to retain the cache between calls to Render-Template, otherwise a new hashtable will be generated for each call to Render-Template. Recursive calls to Render-Template will attempt to reuse the same cache object. During rendering the cache is available as '$__RenderCache'. .PARAMETER StartTag Tag used to indicate the start of a section in the text that should be interpolated. This string will be treated as a regular expression, so any special characters ('*', '+', '[', ']', '(', ')', '\', '?', '{', '}', etc) should be escaped with a '\'. The default start tag is '<<'. .PARAMETER EndTag Tag used to indicate the end of a section in the text that should be interpolated. This string will be treated as a regular expression, so any special characters ('*', '+', '[', ']', '(', ')', '\', '?', '{', '}', etc) should be escaped with a '\'. The default end tag is '>>'. .EXAMPLE Contents of .\page.template.html: <h1><<$Title>></he1> <h2><<$values.Chapter1>></h2> <<(.\pages\1.html)>> Contents of .\pages\1.html: It was the best of times, it was the worst of times. Running: $details = @{ Title = "A tale of two cities" Chapter1 = "The Period" } Render-Template .\page.template.html $details Will yield: <h1>A tale of two cities</h1> <h2>The Period</h2> It was the best of times, it was the worst of times. .NOTES The markup using the default '<<' and '>>' tags to denote the start and end of an interpolated expression precludes the use of the '>>' output operator in the expressions. This is considered acceptable, since the intention of the expressions is to introduce values into the text, rather than writing to the disk. Any expression that is so complicated that you might need to write to the disk should probably be handled as a closure or a function passed in via the $values parameter, or a file included using a <<()>> expression. Alternatively, you can use the the EndTag parameter top provide another acceptable end tag (e.g. '!>>'). #> function Render-Template{ [CmdletBinding()] param( [parameter( Mandatory=$true, HelpMessage="Path to the template file that should be rendered.
