CSV to JSON

Package ratchet is a library for performing data pipeline / ETL tasks in Go. The main construct in Ratchet is Pipeline. A Pipeline has a series of PipelineStages, which will each perform some type of data processing, and then send new data on to the next stage. Each PipelineStage consists of one or more DataProcessors, which are responsible for receiving, processing, and then sending data on to the next stage of processing. DataProcessors each run in their own goroutine, and therefore all data processing can be executing concurrently. Here is a conceptual drawing of a fairly simple Pipeline: In this example, we have a Pipeline consisting of 3 PipelineStages. The first stage has a DataProcessor that runs queries on a SQL database, the second is doing custom transformation work on that data, and the third stage branches into 2 DataProcessors, one writing the resulting data to a CSV file, and the other inserting into another SQL database. In the example above, Stage 1 and Stage 3 are using built-in DataProcessors (see the "processors" package/subdirectory). However, Stage 2 is using a custom implementation of DataProcessor. By using a combination of built-in processors, and supporting the writing of any Go code to process data, Ratchet makes it possible to write very custom and fast data pipeline systems. See the DataProcessor documentation to learn more. Since each DataProcessor is running in it's own goroutine, SQLReader can continue pulling and sending data while each subsequent stage is also processing data. Optimally-designed pipelines have processors that can each run in an isolated fashion, processing data without having to worry about what's coming next down the pipeline. All data payloads sent between DataProcessors are of type data.JSON ([]byte). This provides a good balance of consistency and flexibility. See the "data" package for details and helper functions for dealing with data.JSON. Another good read for handling JSON data in Go is http://blog.golang.org/json-and-go. Note that many of the concepts in Ratchet were taken from the Golang blog's post on pipelines (http://blog.golang.org/pipelines). While the details discussed in that blog post are largely abstracted away by Ratchet, it is still an interesting read and will help explain the general concepts being applied. There are two ways to construct and run a Pipeline. The first is a basic, non-branching Pipeline. For example: This is a 3-stage Pipeline that queries some SQL data in stage 1, does some custom data transformation in stage 2, and then writes the resulting data to a SQL table in stage 3. The code to create and run this basic Pipeline would look something like: The second way to construct a Pipeline is using a PipelineLayout. This method allows for more complex Pipeline configurations that support branching between stages that are running multiple DataProcessors. Here is a (fairly complex) example: This Pipeline consists of 4 stages where each DataProcessor is choosing which DataProcessors in the subsequent stage should receive the data it sends. The SQLReader in stage 2, for example, is sending data to only 2 processors in the next stage, while the Custom DataProcessor in stage 2 is sending it's data to 3. The code for constructing and running a Pipeline like this would look like: This example is only conceptual, the main points being to explain the flexibility you have when designing your Pipeline's layout and to demonstrate the syntax for constructing a new PipelineLayout.

Package dbdog provides godog steps to handle database state. Databases instances should be configured with Manager.Instances. Table mapper allows customizing decoding string values from godog table cells into Go row structures and back. Delete all rows from table. Populate rows in a database with a gherkin table. Assert rows existence in a database. For each row in gherkin table DB is queried to find a row with WHERE condition that includes provided column values. If a column has NULL value, it is excluded from WHERE condition. Column can contain variable (any unique string starting with $ or other prefix configured with Manager.VarPrefix). If variable has not yet been populated, it is excluded from WHERE condition and populated with value received from database. When this variable is used in next steps, it replaces the value of column with value of variable. Variables can help to assert consistency of dynamic data, for example variable can be populated as ID of one entity and then checked as foreign key value of another entity. This can be especially helpful in cases of UUIDs. If column value represents JSON array or object it is excluded from WHERE condition, value assertion is done by comparing Go value mapped from database row field with Go value mapped from gherkin table cell. Rows can be also loaded from CSV file. It is possible to check table contents exhaustively by adding "only" to step statement. Such assertion will also make sure that total number of rows in database table matches number of rows in gherkin table. Rows can be also loaded from CSV file. Assert no rows exist in a database.

Package freegeoip provides an API for searching the geolocation of IP addresses. It uses a database that can be either a local file or a remote resource from a URL. Local databases are monitored by fsnotify and reloaded when the file is either updated or overwritten. Remote databases are automatically downloaded and updated in background so you can focus on using the API and not managing the database. Also, the freegeoip package provides http handlers that any Go http server (net/http) can use. These handlers can process IP geolocation lookup requests and return data in multiple formats like CSV, XML, JSON and JSONP. It has also an API for supporting custom formats.

Since each DataProcessor is running in it's own goroutine, SQLReader can continue pulling and sending data while each subsequent stage is also processing data. Optimally-designed pipelines have processors that can each run in an isolated fashion, processing data without having to worry about what's coming next down the pipeline. All data payloads sent between DataProcessors are of type data.JSON ([]byte). This provides a good balance of consistency and flexibility. See the "data" package for details and helper functions for dealing with data.JSON. Another good read for handling JSON data in Go is http://blog.golang.org/json-and-go. Note that many of the concepts in Ratchet were taken from the Golang blog's post on pipelines (http://blog.golang.org/pipelines). While the details discussed in that blog post are largely abstracted away by Ratchet, it is still an interesting read and will help explain the general concepts being applied. There are two ways to construct and run a Pipeline. The first is a basic, non-branching Pipeline. For example: This is a 3-stage Pipeline that queries some SQL data in stage 1, does some custom data transformation in stage 2, and then writes the resulting data to a SQL table in stage 3. The code to create and run this basic Pipeline would look something like: The second way to construct a Pipeline is using a PipelineLayout. This method allows for more complex Pipeline configurations that support branching between stages that are running multiple DataProcessors. Here is a (fairly complex) example: This Pipeline consists of 4 stages where each DataProcessor is choosing which DataProcessors in the subsequent stage should receive the data it sends. The SQLReader in stage 2, for example, is sending data to only 2 processors in the next stage, while the Custom DataProcessor in stage 2 is sending it's data to 3. The code for constructing and running a Pipeline like this would look like: This example is only conceptual, the main points being to explain the flexibility you have when designing your Pipeline's layout and to demonstrate the syntax for constructing a new PipelineLayout.

Package freegeoip provides an API for searching the geolocation of IP addresses. It uses a database that can be either a local file or a remote resource from a URL. Local databases are monitored by fsnotify and reloaded when the file is either updated or overwritten. Remote databases are automatically downloaded and updated in background so you can focus on using the API and not managing the database. Also, the freegeoip package provides http handlers that any Go http server (net/http) can use. These handlers can process IP geolocation lookup requests and return data in multiple formats like CSV, XML, JSON and JSONP. It has also an API for supporting custom formats.

Package json2csv provides JSON to CSV functions.

Package ratchet is a library for performing data pipeline / ETL tasks in Go. The main construct in Ratchet is Pipeline. A Pipeline has a series of PipelineStages, which will each perform some type of data processing, and then send new data on to the next stage. Each PipelineStage consists of one or more DataProcessors, which are responsible for receiving, processing, and then sending data on to the next stage of processing. DataProcessors each run in their own goroutine, and therefore all data processing can be executing concurrently. Here is a conceptual drawing of a fairly simple Pipeline: In this example, we have a Pipeline consisting of 3 PipelineStages. The first stage has a DataProcessor that runs queries on a SQL database, the second is doing custom transformation work on that data, and the third stage branches into 2 DataProcessors, one writing the resulting data to a CSV file, and the other inserting into another SQL database. In the example above, Stage 1 and Stage 3 are using built-in DataProcessors (see the "processors" package/subdirectory). However, Stage 2 is using a custom implementation of DataProcessor. By using a combination of built-in processors, and supporting the writing of any Go code to process data, Ratchet makes it possible to write very custom and fast data pipeline systems. See the DataProcessor documentation to learn more. Since each DataProcessor is running in it's own goroutine, SQLReader can continue pulling and sending data while each subsequent stage is also processing data. Optimally-designed pipelines have processors that can each run in an isolated fashion, processing data without having to worry about what's coming next down the pipeline. All data payloads sent between DataProcessors are of type data.JSON ([]byte). This provides a good balance of consistency and flexibility. See the "data" package for details and helper functions for dealing with data.JSON. Another good read for handling JSON data in Go is http://blog.golang.org/json-and-go.

Package decoder - this unmarshals or decodes values from a consul KV store into a struct. The following types are supported: By default, the decoder packages looks for the struct tag "decoder". However, this can be overridden inside the Decoder struct as shown below. For the purposes of examples, we'll stick with the default "decoder" tag. By default, in the absence of a decoder tag, it will look for a consul key name with the same name as the struct field. Only exported struct fields are considered. The name comparison is case-insensitive by default, but this is configurable in the Decoder struct. the tag "-" indicates to skip the field. The modifier ",json" appended to the end signals that the value is to be interpreted as json and unmarshaled rather than interpreted. Similarly, the modififier ",csv" allows comma separated values to be read into a slice, and ",ssv" allows space separated values to be read intoa slice. For csv and ssv, slices of string, numeric and boolean are supported.

Package redpanda is the SDK for Redpanda's inline Data Transforms, based on WebAssembly. This library provides a framework for transforming records written within Redpanda from an input to an output topic. This example shows the basic usage of the package: This is a "transform" that does nothing but copies the same data to an new topic. This example shows a filter that uses a regexp to filter records from one topic into another. The filter can be determined when the transform is deployed by using environment variables to specify the pattern. This example shows a transform that converts CSV into JSON.

Package dbsteps provides godog steps to handle database state. Databases instances should be configured with Manager.Instances. Table mapper allows customizing decoding string values from godog table cells into Go row structures and back. Delete all rows from table. Populate rows in a database with a gherkin table. Assert rows existence in a database. For each row in gherkin table DB is queried to find a row with WHERE condition that includes provided column values. If a column has NULL value, it is excluded from WHERE condition. Column can contain variable (any unique string starting with $ or other prefix configured with Manager.VarPrefix). If variable has not yet been populated, it is excluded from WHERE condition and populated with value received from database. When this variable is used in next steps, it replaces the value of column with value of variable. Variables can help to assert consistency of dynamic data, for example variable can be populated as ID of one entity and then checked as foreign key value of another entity. This can be especially helpful in cases of UUIDs. If column value represents JSON array or object it is excluded from WHERE condition, value assertion is done by comparing Go value mapped from database row field with Go value mapped from gherkin table cell. Rows can be also loaded from CSV file. It is possible to check table contents exhaustively by adding "only" to step statement. Such assertion will also make sure that total number of rows in database table matches number of rows in gherkin table. Rows can be also loaded from CSV file. Assert no rows exist in a database.

Package redpanda is the SDK for Redpanda's inline Data Transforms, based on WebAssembly. This library provides a framework for transforming records written within Redpanda from an input to an output topic. Schema registry users can interact with schema registry using a built-in client. This example shows the basic usage of the package: This is a transform that does nothing but copies the same data to an new topic. This example shows a transform that converts CSV into JSON. This example shows a filter that outputs only valid JSON into the output topic.

An implementation of the [Porter2 Stemmer](https://snowballstem.org/algorithms/english/stemmer.html). Port: synonym: harbor Arbor: synonym: stem (More a suffix than a stem, but close enough.) Assuming you already have Golang installed, run the following command to generate an executable named ```harbor``` in whatever directory you're in: For information on how to use the harbor command run: The harbor command has very few options. To process STDIN, set the last argument to a dash ("-"): ./harbor - As another example: cat file.txt | ./harbor - To process a file, pass it as the last argument: ./harbor file.txt You can pass as many files as you want, each will be processed serially in the sequence given. To modify the output format, pass it as a string value assigned to the format flag ("-f"): ./harbor -f '{{range .}}{{printf "%%s\n" .Stem}}{{end}}' file.txt The type to be formated is a slice of structs, where each struct has three fields: Pos, Word, and Stem. The Pos field stores the byte position in the input where the word was found. Word and Stem are what they sound like. For more information on valid values for this flag, see https://golang.org/pkg/text/template/ To modify the output format using a built-in formatter, pass one of the following values to the format flag: - "default": This is the format used when the format flag is left unspecified: ./harbor -f "default" file.txt - "plain": This provides each Stem on it's own line: ./harbor -f "plain" file.txt - "compact": This provides each Stem separated by a space: ./harbor -f "compact" file.txt - "csv": Stem and Word use the string %%q format: https://golang.org/pkg/fmt/: ./harbor -f "csv" file.txt - "json": This uses a template func 'inner', which is available in any format: ./harbor -f "json" file.txt Assuming you're using Golang modules, the following is an example of using the harbor library in a Golang project:

Package json2csv provides JSON to CSV functions.

Package streamcache implements an in-memory cache mechanism that allows multiple callers to read some or all of the contents of a source reader, while only reading from the source reader once; when there's only one final reader remaining, the cache is discarded and the final reader reads directly from the source. Let's say we're reading from stdin. For example: In this scenario, myprogram wants to detect the type of data in the file/pipe, and then print it out. That sampling could be done in a separate goroutine per sampler type. The input file could be, let's say, a CSV file, or a JSON file. The obvious approach is to inspect the first few lines of the input, and check if the input is either valid CSV, or valid JSON. After that process, let's say we want to dump out the entire contents of the input. Package streamcache provides a facility to create a caching Stream from an underlying io.Reader (os.Stdin in this scenario), and spawn multiple readers, each of which can operate independently, in their own goroutines if desired. The underlying source (again, os.Stdin in this scenario) will only be read from once, but its data is available to multiple readers, because that data is cached in memory. That is, until after Stream.Seal is invoked: when there's only one final reader left, the cache is discarded, and the final reader reads directly from the underlying source. The entrypoint to this package is streamcache.New, which returns a new Stream instance, from which readers can be created via Stream.NewReader.

package downtable generates markdown tables from csv and json files. there is methods for modifying the table data before generating the markdown table. to parse an csv file as a input for the markdown table you need to use the WithCSVFile function inside of the [AddTable] method on the MarkdownTable interface. csv data needs to have the first row be the headers and the subsequent rows will be general rows within the table. when using providing a csv file you need to enable formatting options based on the type of csv file, options `lazyQuotes` " double quotes are allowed in csv fields and `trimLeadingQuotes` leading white spaces in the csv field is ignored. json files are also able to provided as input for markdown tables, using the MarkdownTable method [AddJSONFileTable]. to parse json files the package requires the following format: main idea is to use the MarkdownTable interface to parse array strings and produce a string of markdown that represents a table.
