[go-nuts] text template and white space suppression

[Bill Nixon]

I am trying to do some creative formatting using text template and wanted 
to see if there might be a better approach than what I implemented.

I have an array of structs, where each element has a Project and Task. The 
array is sorted by Project.
type DisplayTask struct {
 Project string
 Task string
}

I want to output all the tasks within a project without repeating the 
project name each time and I want the tasks to be indented, for example:

Project1 
  Task1
  Task2
Project2 
  Task3
Project3 
  Task4
  Task5

After much experimentation, I am using the following template and trying to 
determine if there is a way to avoid the printf and just have the indent as 
part of the template, but I can't figure out a way to do this and suppress 
white space (newline) from the if statement for the same project.
{{- $lastProject := "" -}}
{{ range . }}
{{- if (ne $lastProject .Project) -}}
{{ .Project }} {{ $lastProject = .Project }}
{{ end -}}
  {{ printf "  %s" .Task }}
{{ end -}}

Go Playground of the working code is at 
https://play.golang.org/p/3qqVW8lN-Ha

The challenge I had was suppressing white space after the end, but still 
allowing an indent via white space, so resorted to the printf.

Is there a better way?

[go-nuts] Microsoft Graph for Go

[Bill Nixon]

I've been playing with Go and Microsoft Graph and decided to combine the 
two and have been writing a "wrapper" API to the RESTful Microsoft Graph 
APIs.The source is available at https://github.com/bnixon67/msgraph4go

Microsoft Graph exposes REST APIs and client libraries to access data on 
various Microsoft cloud services, including OneDrive, OneNote, 
Outlook/Exchange, SharePoint, Azure Active Directory, etc...

There are SDKs for some popular languages, but I didn't find any for Go.

This has been a great learning experience and I've been impressed with how 
easily Go supports this type of work, with standard libraries for OAuth2, 
HTTP requests, JSON conversion to Go types, etc...

I welcome any feedback or input. I plan to continue to expand the package 
to support more of the Microsoft Graph APIs. So far, I've only done 
read-only operations, but I am considering writing a OneDrive Sync client.

Thanks,
Bill

[go-nuts] Re: golang tool for splitting long lines

[Bill Nixon]

I agree json.MarshalIndent is great. However, be aware that 
json.MarshalIndent will not output private (lowercase) fields of the struct.
