This example illustrates a PowerShell script that extracts a changeset ID from a Git commit message using two different approaches. It first demonstrates a successful method using a `Where-Object` pipeline with a regular expression, followed by a direct `-Match` operator, both printing the captured group to the console. The script then shows a commented-out version where the `-Match` operator fails, producing a "Cannot index into a null array" error, highlighting the difference in handling matched results. The code relies on PowerShell's built-in regex matching and `Write-Host`, drawing data from `git log`.

Reveiw #1

This example shows a PowerShell script that syncs a Perforce workspace to Git, converting individual Perforce changelists into Git commits on a dedicated branch. It queries `p4 changes` and `p4 users` to gather changelist metadata and author information, then iterates through each changelist, updating the workspace with `p4 sync` and committing changes via `git add` and `git commit` on behalf of the original Perforce users. A preview mode optionally prints changelist details without executing the commits. The script relies on command-line tools rather than a visualization library, performing no graphical rendering.

Adds GitExtensions support to the git bash

This example demonstrates a PowerShell script that configures the Git Bash environment to integrate with GitExtensions. The script first detects the operating system architecture using `Get-WMIObject` to determine the appropriate Git installation path, then modifies the system `PATH` variable by appending the Git directory. It subsequently creates a `git-ex` file in the Git `bin` folder, writing a shell script content that launches `GitExtensions.exe` with any passed arguments. The code uses PowerShell's `Write-Host` for user feedback and `Test-Path` and `New-Item` for file operations.

This example demonstrates a PowerShell script that processes a text file by replacing caret characters with semicolons and writes the result to a new file. It shows a batch text-transformation workflow using the `Get-Content` cmdlet to read input in chunks of 1000 lines, a custom filter function `replace-chars` that applies the `-replace` operator, and `Add-Content` to append the processed lines to the output file. The script first checks if the output file exists and clears it to ensure a fresh write. The approach highlights pipeline-based file handling and character encoding preservation without additional libraries.

My PowerShell profile. To edit yours type `code $profile`

This example visualizes a developer’s PowerShell profile, showing how aliases and functions streamline common workflows. It renders the profile’s source code as text, highlighting the use of posh-git for prompt customization and the `Set-Alias` and `function` keywords to map commands like `yarn build` to `b`. The code also references `$GitPromptSettings` to adjust the prompt’s prefix and suffix, and sets environment variables like `$HOME`. The visualization is a static code snippet, with no external libraries or data sources beyond the profile’s own content.

This visualization demonstrates the interaction between R and PowerShell, showing how a system call from an R environment triggers a PowerShell script that manipulates data. The code uses the `system2` function to execute a PowerShell command with a specified file path, passing arguments to run `coolScript.ps1`. The example highlights the practical integration of two scripting environments, where R serves as the orchestrator for external process execution. The rendering relies on the command-line interface rather than graphical libraries, focusing on the workflow of invoking and managing external scripts from within an R session. The data flow is implicit in the script's execution, emphasizing interoperability over visual output.

Fetching Remove Password comments from Github. Using Power Query and R

This example visualizes a GitHub code search for commits that remove passwords, using a Power Query workflow that calls the GitHub Search API to collect matching commits and their file patches. The data flows through Power Query’s table expansion functions before being handed to an R script via `R.Execute`, where a regular expression pattern extracts only the removed lines from each patch. The final table retains the commit metadata and the cleaned removed-line text, omitting the original patch column. The visualization demonstrates a hybrid ETL pipeline combining GitHub’s REST API, Power Query’s M language, and base R string processing.

Git Tips and Tricls

This visualization presents a collection of Git command-line tips and tricks, sourced from a gist by MrSteve2. It displays the commands as text-based data, showing both the raw shell syntax and the intended purpose of each operation. The example uses plain text rendering without any specific charting libraries or APIs, relying on a straightforward textual layout to present the commands and their descriptions. The data is encoded directly in the gist file as a list of shell commands, such as using `git branch | grep -v master | xargs git branch -D` for cleaning up local branches, and `git config --global push.default current` for changing push behavior.

This example visualizes a command-line prompt configuration that dynamically displays the current Git branch and working-directory status in color. It shows how the prompt turns red when uncommitted changes exist and green when the working directory is clean. The shell script uses `parse_git_branch` with `sed` and `awk`-style piping to extract branch names, while `check_git_changes` relies on `git status` and `tput setaf` to set terminal colors. The PS1 variable composes the final prompt, embedding the branch name and status indicator between the directory path and a colon. It relies on standard Bash and Git command-line tools, not a visualization library.
