Redmine REST API client

This is a lightweight Redmine API client.

Introduction

Caution

I created it for my own personal use (while I was learning the Go language), you probably shouldn't use it! At least until it ready for production: ver >= 1.0.

I wanted create something like TUI of Redmine, but when i dive into learning of TUI libs like bubbletea, i spent all my free time slots and this idea was on pause for a while...until once i needed small lib to get all my time entries from redmine to build over this one some another cool TUI app.

So basically this lib, a Go module, used for scroll over all Redmine time entries.

Another functional will be added (maybe) later...

Installation

go get github.com/1buran/redmine

Usage

Supported Redmine types:

• User
• Project
• TimeEntry
• Issue

// Configure the time entries filter: set start and end date of time frame and user id
// for whom you want to get time entries
start := time.Date(2024, time.March, 1, 0, 0, 0, 0, time.UTC)
end := start.AddDate(0, 0, 30)

timeEntriesFilter := redmine.TimeEntriesFilter{
    StartDate: start,
    EndDate: end,
    UserId: "1"
}

// Create api config: set Redmine REST API url, token, enable or disable logging
apiConfig := redmine.ApiConfig{
    Url: "https://example.com",
    Token: "asdadwwefwefwf",
    LogEnabled: true,
    timeEntriesFilter
}

// Open the channels to data and errors from the redmine client:
// dataChan, errChan := redmine.Scroll[redmine.Project](&apiConfig)
// dataChan, errChan := redmine.Scroll[redmine.Issue](&apiConfig)
dataChan, errChan := redmine.Scroll[redmine.TimeEntry](&apiConfig)
for {
    select {
    case t, ok := <-dataChan:
        if ok { // data channel is open
            // perform action on the gotten item e.g. print the data
            fmt.Printf("On %s user spent %.2f hours for %s\n", t.SpentOn, t.Hours, t.Comment)
            continue // go to the next iter of for loop
        }
        return // data channel is closed, all data is transmitted, return to the main loop
    case err, ok := <-errChan:
        if ok { // err channel is open
            // perform action depending on the gotten error and your business logic
            switch {
                case errors.Is(err, redmine.ApiEndpointUrlFatalError):
                    fmt.Fatalf("redmine api url is malformed: %s", err)
                case errors.Is(err, redmine.HttpError):
                    fmt.Println("http error: %s, retry...", err)
                default:
                    fmt.Println("err: %s", err)
            }
        }
    }
}

There are some custom error types, from low level to high level errors which are aggregates of first ones. Typically you should be expect only these high level errors in errChan:

• JsonDecodeError: errors related to unmarshaling redmine server response
• IoReadError: errors related to read input (io.ReadAll(body))
• HttpError: errors related to network layer (http_client.Do(req))
• ApiEndpointUrlFatalError: fatal errors that means that most probably the url of redmine api is malformed or bogus, please check it
• ApiNewRequestFatalError: actually will not be thrown (see the comments in code)
