Available as Nuget package
A simple crontab parser. This can be used in conjunction with a timer to verify if a certain operation have to be run.
It defines a Crontab class that, starting at a certain date time, would be allowed to run every certain amount of milliseconds
void Initialize()
{
//Starting time
var startAt = DateTime.Parse("26/10/2009 8:47:39 AM",CultureInfo.GetCultureInfo("en-GB"));
//From now, every 5000 ms
var target = new Crontab(startAt, 5000);
//Calculate the first time that the action must be run
var next = target.Next(DateTime.Now);
var toWait = (next- DateTime.Now).TotalMilliseconds;
//Initialize a timer to run after the needed time
if(toWait>0){
var timer = new Timer(toWait);
timer.Elapsed += OnTimerElapsed;
}
}
It defines a Crontab class that would give the "next" time given a certain crontab definition
Format string with spaces between the entries * * * * * * * command to be executed - - - - - - - | | | | | | +----- year | | | | | +----- day of week (0 - 6) (Sunday=0) | | | | +------- month (1 - 12) | | | +--------- day of month (1 - 31) | | +----------- hour (0 - 23) | +------------- min (0 - 59) +------------- sec (0 - 59)
For an usage example:
public void Initialize()
{
var target = new Crontab("10 */1 * * * * *", true);
//Calculate the first time that the action must be run
var next = target.Next(DateTime.Now);
var toWait = (next- DateTime.Now).TotalMilliseconds;
//Initialize a timer to run after the needed time
if(toWait>0){
var timer = new Timer(toWait);
timer.Elapsed += OnTimerElapsed;
}
}
An utility class to load easily the resources as binary or as text.
The most important thing is that given ONLY the partial file name the resource is searched inside the assemblies.
That means that if is present a resource named "ms.apackage.anotherpackage.resource.txt" it can be found with the names:
The available functions are:
Needed to parse the command line parameters.
Can show an help is something goes wrong. With the default -h or -help flags. Usually I store it in a resource file and load it through the ResourceContentLoader.
Loads even the environment variables in the same dictionary of the command line arguments
For an usage example, calling the executable as:
MyExecutable -test -parameter parameterValue
public void Main(string[] args)
{
const string helpString = "The help message";
var commandLineParser = new CommandLineParser(args, helpString);
if(commandLineParser.Has("test")){
//Do something
}else if(commandLineParser.Has("parameter"){
var parameterValue = commandLineParser["parameter"];
//Do something
}else{
//Something went wrong..so show the help
commandLineParser.ShowHelp();
}
}
The available functions are: * [string]: To get and set variables * string GetEnv(string name): To get an environment variable * void SetEnv(string name,string value): To set an environment variable. Stored on the CommandLineParser instance ONLY. * bool IsSet(string name): To check if a variable exists * bool Has(params string[] names): To check if all the passed variables are set * bool HasAllOrNone(params string[] names): To check if all variables are set, or none of them * bool HasOneAndOnlyOne(params string[] names): To check if ONLY one variable between the required is set * void ShowHelp(): Show the help string * string Help: Get the help string
An utility to work with assemblies and type:
