Last Commit info–GitHub and AzureDevOps–part 39

I was thinking that I need to see the date of last CD – who done what. For this,I need 2 things: to have a controller/gui to show the info and the CD process,via GitHub/AzureDevOps,to take care of that.

For the part with code,the problem was pretty simple:

using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace InfoValutarWebAPI.Controllers
{
    /// <summary>
    /// info about commit
    /// </summary>
    public class LastCommitInfo
    {
        /// <summary>
        /// comment latest commit
        /// </summary>
        public string LatestCommit { get; set; }
        /// <summary>
        /// last date of commit
        /// </summary>
        public DateTime DateCommit { get; set; }
        /// <summary>
        /// last author of commit
        /// </summary>
        public string LastAuthor { get; set; }
    }
    /// <summary>
    /// controller about info the application
    /// </summary>
    [ApiController]
    [ApiVersion("1.0")]
    [Route("api/v{version:apiVersion}/rates")]
    public class InfoController
    {
        /// <summary>
        /// info about latest commit
        /// </summary>
        /// <returns></returns>
        public LastCommitInfo GetLatestCommit()
        {
            return
                new LastCommitInfo()
                {
                    LatestCommit = "{LatestCommit}",
                    DateCommit = DateTime.ParseExact("{DateCommit}","yyyyMMdd:HHmmss",null),
                    LastAuthor = "{LastAuthor}"
                }
                ;
        }
    }
}

What about the CD process ?

Well,this was cumbersome. To see ALL the environment  variables,I used cmd /K set ( in command ) or Get-ChildItem Env: ( in powershell).

And I come with this:

A bash script to take the version

– bash: |

git log –format=’%s’ -1

git log –pretty=oneline | head -1

gitMessage=$(git log –format=’%s’ -1)

echo “##vso[task.setvariable variable=commitMessage;isOutput=true]$gitMessage”

displayName: Store commit message in variable

– powershell: .\modifyinfo.ps1

displayName: modify info

And a  .ps1 powershell

$file = “.\InfoValutar\InfoValutarWebAPI\Controllers\InfoController.cs”

$date = Get-Date -Format “yyyyMMdd:HHmmss”

Get-ChildItem Env:

$author= $Env:BUILD_SOURCEVERSIONAUTHOR

$commitText = $env:BASH_COMMITMESSAGE

((Get-Content -path $file -Raw) -replace ‘{LatestCommit}’,$commitText -replace ‘{LastAuthor}’,$author -replace ‘{DateCommit}’,$date ) | Set-Content -Path $file

(Get-Content -path $file -Raw)
