While the main purpose of the CodeCharta Shell (ccsh) is to use its various tools to generate metrics from code, it also provides some functionality to help users achieve that, independently of the used tool.

General usagePermalink

After the CodeCharta analysis has been installed, executing ccsh -h should show the help where all further are listed. Most often the CodeCharta shell is called with one of its tools to perform different actions. For example ccsh csvimport example.csv will use the CSVImporter to turn the given csv file into cc.json format. More information on how to the CodeCharta Shell can be found in the pages of the individual analysis tools or in our How-to articles.

Interactive ShellPermalink

The interactive shell aims to aid users when executing parsers by collecting all needed options and arguments for the corresponding parser. You can launch the interactive shell by calling ccsh -i or ccsh --interactive. There you are asked which parser you want to run and receive questions helping you configure that parser.

Alternatively, you can directly run the interactive dialog for a parser by calling it without arguments, e.g. ccsh sonarimport.

In the end, the full command to launch the parser in the configured way is output for future use and the configured parser is executed.

Parser SuggestionsPermalink

When launching CodeCharta Shell without any arguments and options, CodeCharta automatically tries to suggest applicable parsers to the user. To do this, a resource has to be entered which can be a path to a file, folder or an url. CodeCharta then automatically checks all parsers which support this feature and offers the user to select from a list of all parsers which have been identified as applicable.

After choosing the parsers, a dry run to configure each parser is started using the Interactive Shell. When all parsers are configured, the user can either manually run the parsers by executing the command output by the Interactive Shell or run them together automatically. If the latter option is selected, all configured parsers are run in parallel.

If every parser is run successfully, the shell offers the user to merge the result files. To do that, each parsers result cc.json has to be moved into the same folder.

Currently, the following parsers are considered when checking for recommendations:

  • GitLogParser
  • SVNLogParser
  • SonarImporter
  • MetricGardenerImporter
  • SourceCodeParser
  • RawTextParser

Combining multiple metricsPermalink

You can combine multiple metrics into one .cc.json. This allows users to analyze a codebase with multiple tools (e.g. the sonarimporter for code metrics like complexity and the gitlogparser for metadata like number of authors) and combine the results in a single file that can be visualized. This is done with the Merge Filter. Some importers support direct pipe-through, which means you don’t need to use the merge filter. If these importers are missing a metric, please take a look at Custom Metrics and Importer.

Piped input for filtersPermalink

Instead of providing a cc.json file as input, a project can also be piped to the filter:

cat demo.cc.json | ccsh modify -p=2

This behaviour is currently supported by ccsh modify, ccsh merge and ccsh edgefilter

Validating cc.json filesPermalink

CodeCharta also provides the ccsh check command, which can verify the syntax of a cc.json file. This can be useful in case you want to manually create or modify a cc.json file. While it is possible, we advise against manually adjusting cc.json files. If you want to use metrics that are not available with our tools, it is much easier and safer to create them in CSV format and user our CSVimporter.
