To install and use the latest stable version of dougerino, install from this GitHub repo's master branch with this command:
pip install git+https://github.com/dmahugh/dougerino.git@master
Note that dougerino library requires the requests package as well as several Azure packages. See requirements.txt and setup.py for more information.
Dougerino is a work in progress — pull requests, feature requests and issues welcome. I've implemented functionality as I need it for various projects, but I'm interested in knowing what other types of functionality may be useful to others. Please log an issue if you have a suggestion. Thanks!

Returns a weekday name, arguments can be a date, datetime, or year/month/day.
This class is a context manager for changing to another directory and then reverting to the prior working directory when done.
from dougerino import ChangeDirectory
with ChangeDirectory(folder):
pass # code that should run in folder
# returns to previous working directory when doneCross-platform clear-screen function for console apps.
Function arguments: csvfile, column
Counts the occurences of each distinct value in a specified column of a CSV file. Returns a dictionary whose keys are the distinct values, and the value of each dictionary entry is the count for that distinct value.
Function arguments: filename, key_column, val_column, lower, header
Returns a dictionary with one entry for each row in a specified CSV file, using the specified columns for the dictionary's key/value pairs. Optional arguments for whether to make all keys lower-case (default=True) and whether the CSV file has a header row (default=True).
Arguments: csvdata, header
Returns a JSON object (list of dictionaries) that contains all of the data from the contents of a CSV file (passed as a string). Optional parameter to indicate whether the CSV data includes a header row (default=True). If no header row, the dictionaries have keys named field0, field1, etc.
Arguments: filename, column, lower, header, dedupe
Returns a specified column number (0-based) of a CSV file as a list. Optional parameters for whether to return values as lower-case (default=True), whether the CSV file has a header (default=True), and whether to eliminate duplicate entries in the list (default=True).
Return number of days that have passed since a specified date. Date is passed as a string, YYYY-MM-DD format.
Write a specified list of dictionaries (as returned by json.loads()) to a specified CSV file.
Write a specified list of dictionaries (as returned by json.loads()) to a specified JSON file.
Returns byte size for a specified filename. (Wrapper around os.stat().st_size.)
Retrieves data from the GitHub V3 REST API, and handles pagination so that all instances of the requested entity type are returned in a single list of dictionaries.
This function parses the 'link' HTTP header returned by the GitHub V3 REST API, and returns a dictionary that can be used to navigate paged results. For example, here is the content of a link header:
<https://api.github.com/organizations/6154722/repos?page=2>; rel="next", <https://api.github.com/organizations/6154722/repos?page=98>; rel="last"
And here is the dictionary returned by github_pagination() for that header:
{
"firstpage": 0,
"firstURL": None,
"lastpage": "98",
"lastURL": "https://api.github.com/organizations/6154722/repos?page=98",
"prevpage": 0,
"prevURL": None,
"nextpage": "2",
"nextURL": "https://api.github.com/organizations/6154722/repos?page=2",
}Wrapper function for querying the GitHub V3 REST APIs.
Arguments: jsondata, header (default=True)
Converts a JSON document (string) to a CSV representation (string).
Note that this function takes a string version of the JSON data, because
it is commonly used with data read from a file. E.g., open('filename.json').read().
Returns a comma-delimited string containing specified values from a list.
Returns percentage for specified value and total.
Arguments: filename, numlines (default=1)
Prints to the console the specified number of lines of a text file. Commonly used for quickly peeking at the beginning of a very large CSV file.
Display on the console a text-based progress bar showing completion status.
print('Example of using progressbar() function ...')
progressbar.lastdisplay = ''
for progress_value in range(100):
progressbar(progress_value/100, bar_length=80, done_char='#')
time.sleep(.02)
progressbar(1, bar_length=80, done_char='#') # 1 = 100% finishedArguments: topic, section, key
Confidential information such as access tokens and passwords is stored in
topic-based INI files in the ..\_private folder, to avoid any risk
of committing this information to GitHub. This function is used to retrieve
those values. Topic is the name of the INI file (not including the .ini
extension), section refers to a section within the INI file, and key is
the name of the desired value within the section.
Returns a timestamp string for a specified file, or for the current date/time if no file specified.
Arguments: fromdate, todate
Returns the difference in years between two dates. Arguments can be date/datetime objects or strings in month/day/year format.
