exercism-config-visualizations

A collection of cross-track configuration visualizations for Exercism.

Install

npm install -g exercism-config-visualizations

Usage

exercism-config-visualizations --format csv --uniconfig ./data/uniconfig.json averages

• format - choose the output format for the output, defaults to md (markdown)
• uniconfig - the location of your uniconfig file, defaults to internal (probably outdated) uniconfig. May also be provided via stdin

Uniconfig

This program uses for input a unified Exercism configuration file (the --uniconfig option or piped in via stdin) you may need to re-generate it from exercism-uniconfig. There is one used by default but it may be outdated.

You can pipe the input from exercism-uniconfig directly into this program.

exercism-uniconfig | exercism-config-visualizations topics

It is more efficient to save it locally as a file and re-use that.

Output Format

You may output the results of a standard report in a number of formats.

• md - a markdown table, good for including in GitHub text (default)
• csv - useful for opening as a spreadsheet program or piping to another processor
• table - a no-frills text-based table
• json - a JSON file with output data multi-dimensional array.

Contribute

This has been designed to make it easy to create your own reports. Make a file named with the slug for your report in reports. See the exercise-count report as a good example of how to make a new report. I encourage others to submit any interesting reports for inclusion in the tool.

If you return false the program will assume you handled output yourself. Otherwise return a string for that output. If you want to take advantage of CSV or tabular output return a multi-dimensional array with headers as the first row.
