Adding repo name to bash prompt string

Overriding the custom prompt

To overwrite the default bash prompt string, also known as PS1(prompt string one), create a file name at ~/.config/git/git-prompt.sh

e.g. C:/Users/ItsMe/.config/git/git-prompt.sh

You'll need to set a variable named PS1. Here's a very simple example of a custom prompt of "hello" followed by a newline and the classic '$' symbol:

PS1="hello\n$ "

Uploading to dropbox using the sdk

I used to move my files into a dropbox enabled folder and let them deal with the uploading but that feature has become so unreliable to be uesless to me. Instead I've written this python3 script to upload files using the dropbox sdk instead.

Downloading the dropbox python sdk is as easy as:

 pip install dropbox

 If your file is less than 150MB then dropbox.files_upload can be used, larger than that and dropbox.files_upload_session_start must be called and given a small chunk of your file, with the remaining chunks being uploaded with dropbox.files_upload_session_append and the final chunk with  dropbox.files_upload_session_finish.  

What a faff! So this script will do it all for you and print out a nice progress bar too :) 

 
This has been sped up a lot

Call with upload_to_dropbox(file_path, target_path) where file_path is the file you want to upload and target_path is the dropbox location (including the uploaded file name).
It will also return a True value if the upload was successful.

I work out the dropbox location by finding the folder I want in a browser and getting the url
e.g. "https://www.dropbox.com/home/Projects/Groobles%20Files"
Then remove the dropbox.com/home bit and replace %20s with the spaces they represent, then add the file name
e.g. "/Projects/Groobles Files/uploadedfile.zip"

The script:

import os
import math
import dropbox

## Token required to access dropbox
ACCESS_TOKEN="ABCDEFGHIJKLMNOP1234567890SECRETTOKEN0000"

class UploadProgressBar:    
    def __init__(self, file_size, bar_length=20):

        self.bar_length = bar_length
        self.progress = 0
        guide_bar_string=" "
        for _ in range(bar_length):
            guide_bar_string+="_"
        print(guide_bar_string)
        print("|", end="")#start of progress bar
    def updateProgress(self, uploaded_data):
        """! Update the bars progress level.

How to manually link IPP libraries

 IPP or oneAPI installs a visual studio extension that does all this linking for you, but if you are using a version of visual studio that is no longer supported, or if the extension just isn't installing for you for some reason (like I found...) then here's how to static link it manually.

You may need to add additional libraries for your needs but this is the gist of it:

How to set up an automatic "good morning" slack messenger

 My boss wants us to greet the team every morning but I'm a busy woman so here's how I automated a "good morning" message to slack every day from my PC.

  • Step 1: Generate a user token

We need a user token to authorise messages send to the slack API, these are tokens that start with "xoxp". If you don't already have one, we'll have to create a slack app, install it to our slack workspace, and give it "user:chat" permissions to generate a token.
    1. Go to https://api.slack.com/apps/ to create a new app. It will need to be made on the same workspace you're "good morning" messages will be posted to
    2. In your new app, go to "App Manifest" in the settings menu on the left then click "Edit"
    3. In the manifest add a "user" to the oauth_config scopes and give it "char:write" permissions e.g.:
      oauth_config:
        scopes:
          user:
            - chat:write
    4. Now go to "OAuth & Permissions" in the settings menu and we should now have a User OAuth Token. 
    5. Install/reinstall your app to the workspace. There should be a prompt asking you to do so (You'll need to do that every time you make any change to the app)

You'll need to provide these arguments:
- token (your user token)
- channel (the channel to post the message)
- as_user (set to true)

There are multiple ways to do this, check out the API link above for more info. But I'm going to use a batch script and http for simplicity.

I've also randomised my message slightly for variety.

set min=1
set max=3
set /a selectionNum=(%RANDOM%*max/32768)+min

if %selectionNum%==1 (
set message=good morning
goto sendmsg
)
if %selectionNum%==2 (
set message=good morning :slightly_smiling_face:
goto sendmsg
)
if %selectionNum%==3 (
set message=morning!
goto sendmsg
)

:sendmsg
curl -d "text=%message%" -d "channel=general" -d "as_user=true" -H "Authorization: Bearer xoxp-xxxxxx-xxxxxx-xxxxxx-xxxxxx" -X POST https://slack.com/api/chat.postMessage

  • Step 3: Trigger your script in the morning
On Linux or Mac you can set up a cron job, I'm on Windows so I'm going to use the Task Scheduler.
  1. Open Windows Task Scheduler and create a new task
  2. Add a name as description
  3. Click the "Triggers" tag and set the job to run every day at whatever time (chose an slightly off time like 9:08 so the messages look more natural. I've set mine to 9:17 because everyone knows I'm not an early bird)
  4. Click the "Actions" tab and add the path to your script
  5. Save your task
  • Step 4: Carry on with your life!
Your script will be social for you. As long as your computer is on the script will be able to send the message.

"Could not perform submodule update" after jenkins git update

 

This is the error I'm getting after updating the git version on my jenkins server:


 > git.exe config --get submodule.module.url # timeout=10
hudson.plugins.git.GitException: Command "git.exe config --get submodule.my-module.url" returned status code 1:
...
Caused: java.io.IOException: Could not perform submodule update
...
Finished: FAILURE



My solution was opening the .gitmodules file (a hidden file, found in the repo root) and adding "'.git" to the end of the url.

e.g.:
[submodule "my-module"]
path = my-module
url = git@bitbucket.org:name/my-module.git

pkgbuild basics - Creating a basic pkg installer on OSX


pkguild is a command-line tool used to create installers, there are easier tools for creating installers such as Packages which uses a graphical user interface.

The way pkgbuild works is that you create a folder structure that acts as the root directory of the target machine, then you move the files for the installer into this fake root folder with the desired folder structure. 
When you run the pkgbuild command you tell it what the root folder is and pkbuild essentially trims off that part of the file path to figure out where to install your files.
The result will be an installer (.pkg file) that will install your files and look something like this:
Image of an installer dialog for example project myapp

In this example I've created a directory called "instroot" in my documents. 
I want "myApp" to be installed at /Applications/myApp so I've copied it to the new folder:
~/Documents/instroot/Applications/MyApp

I also want some text files to be installed at /Library/Application Support/myApp so I've copied them into the new folder too:
~/Documents/instroot/Library/Application Support/myApp/myAppFile1.txt





once all the files for the installer are in the correct place, we just need to call this command:

pkgbuild --root --identifier --version packagename

root: the install root
identifier: an ID for your installer (used only by the operating system and can be anything you want but so try to make it meaningful and unique)
version: the version of your project
packagename: the name for the output installer, the name is also used in the installer dialog

for my example project the command is:

pkgbuild --root ~/Documents/instroot --identifier com.myapp.test --version 1.0 myapp.pkg


We can also use the pkgutil --payload-files command to list the installer files and sanity check the contents.

Now we have an installer called myapp.pkg! Double clicking it will start the installer.
