I use Toggl (https://toggl.com/) to track my daily time. It’s a nice system that is free with lots of reports and such. However, one report that I needed is not available. Fortunately, there is a nice API available to extract your data as needed.
The report that I needed was one that would give me weekly summaries of project time for a given calendar month. Toggl has monthly, daily, and weekly reports. The monthly report would group/sum all time for the month by project without a weekly break-down. The weekly report does not let you select partial weeks. So, you wind up, potentially, with weeks from multiple months in the report. The daily report shows all daily time without grouping.
After a quick review of their API, I decided to use their detail report output with some some simple LINQ grouping to generate my monthly reports with weekly summaries. To quickly prototype my report, I whipped up a simple LINQpad program to output a Bootstrap styled table.
The code is pretty simple, although there is a fair bit of cruft to make the Http calls and to perform some Log4Net setup. You only need to enter your API token from your Toggl account settings and then change the date indicating which month you’d like to report on. Within the code, I use LINQ groping and such to summarize the times by week. Toggl’s API returns durations as milliseconds, so time durations are easy to work with. I use the TimeSpan class to format the duration outputs.
void Main()
{
var token = "YOURTOKENHERE:api_token"; // <---- put your token here. in the format "XXXXXXXXXXXXX:api_token"
var date = new DateTime(2016,8,1); // <-- set your date here
var startdate = date.ToString("yyyy-MM-dd");
var enddate = date.AddMonths(1).AddDays(-1).ToString("yyyy-MM-dd");
var apiService = new ApiService();
var detailUrl = "https://toggl.com/reports/api/v2/details";
var workspaceUrl = "https://www.toggl.com/api/v8/workspaces";
// Get the first workspace.
dynamic workspaces = apiService.GetFromApi<dynamic>(workspaceUrl, null, token);
var workspace = (string)workspaces[0].id;
var dict = new Dictionary<string, string>() { { "since", startdate }, { "until", enddate }, { "workspace_id", workspace }, { "user_agent", "api_test" } };
DetailReport report = apiService.GetFromApi<DetailReport>(detailUrl, dict, token);
// Group by week, year
var group = report.Data.GroupBy(x => new { Project = x.Project, Week = x.Week }).ToList();
var output = group.Select(g => {
var ts = TimeSpan.FromMilliseconds(g.Sum(p => p.Duration));
var obj = new { Project = g.Key.Project, Week = g.Key.Week, Duration = string.Format("{0:000}:{1:00}:{2:00}",(int)ts.TotalHours, (int)ts.Minutes, (int)ts.Seconds) };
return obj;
})
.OrderBy(x => x.Week)
.ToList();
var total = TimeSpan.FromMilliseconds(report.Data.Sum(p => p.Duration));
output.Add(new {Project = "", Week = "", Duration = ""});
output.Add(new { Project = "Summary", Week = "", Duration = string.Format("{0:000}:{1:00}:{2:00}",(int)total.TotalHours, (int)total.Minutes, (int)total.Seconds)});
var table = @"<html><head><link rel=""stylesheet"" type=""text/css"" href=""https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.css""/></head><body><div class=""container""><table class=""table""><thead class=""thead-default""><tr><th>Project</th><th>Week</th><th>Duration</th></tr></thead><tbody>";
table += string.Join("", output
.GroupBy(x => x.Week)
.Select((g, i) => {
var rowClass = i % 2 == 0 ? "bg-success" : "bg-info";
var groupStr = string.Join("", g.Select(x => { var str =string.Format(@"<tr class=""{0}""><td>{1}</td><td>{2}</td><td>{3}</td></tr>", rowClass, x.Project, x.Week, x.Duration); return str; }).ToList());
return groupStr;

With the LINQPad working, I get a nice HTML table report:
