![]() For example theĬompilationProvider will always produce a single compilation instance, whereas IncrementalValuesProvider may provide zero or more values. Multi Valued providersĪn IncrementalValueProvider will always provide a single value, whereas an That will be applied, rather than the resulting data. They represent the outcome of the transformation Note how transformed and prefixTransform are themselves an Select( static ( path, _) = > "prefix_ " + path) transform each extracted path into something else IncrementalValuesProvider prefixTransform = transformed. apply a 1-to-1 transform on each text, which represents extracting the path IncrementalValuesProvider transformed = additionalTexts. get the additional text provider IncrementalValuesProvider additionalTexts = context. RegisterExecutionPipeline( static context => AnĮxecution pipeline does not access the values in a value provider directly. See SyntaxValueProvider for details.Ī value provider can be thought of as a 'box' that holds the value itself. Note: there is no provider for accessing syntax nodes. IncrementalGeneratorInitializationContext provided during initialization. The plural values) where T is the type of input data that is provided.Īn initial set of providers are created by the host, and can be accessed from the ![]() Input data is available to the pipeline in the form of opaque data sources,Įither an IncrementalValueProvider or IncrementalValuesProvider (note the code in the Where(.) above will not be executed until the value of the additional texts actually changesīetween each transformation, the data produced is cached, allowing previously calculated ![]() IncrementalValuesProvider textFiles = context. ") Īn incremental generator is an implementation of. RegisterSourceOutput( namesAndContents, ( spc, nameAndContent) => generate a class that contains their values as const strings context. Select(( text, cancellationToken) => ( name: Path. read their contents and save their name IncrementalValuesProvider namesAndContents = textFiles. txt IncrementalValuesProvider textFiles = initContext. define the execution pipeline here via a series of transformations: // find all additional files that end with. Public void Initialize( IncrementalGeneratorInitializationContext initContext) All in all something like this sounds like what you want: rsync -av -log-file=/var/log/rsync.Public class Generator : IIncrementalGenerator If you want to log what was changed you can use the "-log-file" option. Rsync doen't care how you got the files in the source, or the destination directories, it's only going to copy the changes between the two, unless you add flags to do something different. Unless you have a lot of churn over your data set. The first run will be BandWidth intensive, the following runs will most likely be processor intensive but use little Bandwidth compared to the initial run. ![]() The next time it runs it'll do a block checksum of the file, and only copy over the parts which have been modified on existing files, copy new files over, and remove files which are no longer there. run rsync with the "-av" flags and have it do a first run against the data you want backed up. Most often the "-a" flag is used which is the "Archive" flag, this is probably what you want. Rsync has a number of flags which control what it will look at and what it will copy over to the destination. ![]()
