Software Developer Profile Builder

StackMuncher app helps developers find work that matches their skills and interests. It analyzes commits in their local Git repositories and builds a profile in the Open Directory of Software Developers.

SPECIAL NOTICE

This project is on hold. Feel free to use the app or fork the code. The cloud infra is running in read-only mode. The DB is not being updated. Any data you submit is dropped on reception.

The code analysis is non-judgemental. It simply collects the facts such as what languages and frameworks are used, number of lines of code or library use. All that data is assembled into a Developer Profile to help someone looking for your skills to find you.

Privacy

All code analysis is done locally. Not a single line of code is leaving your machine.
All identifying and sensitive information such as file, project or private library names is stripped.
Your developer profile is completely anonymous unless you add your name and contact details to it.

The app creates a sample stack report on the first run over a project without submitting it (dryrun). You can review the report before continuing.

Examples

anonymous profile: https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK
public profile: https://stackmuncher.com/rimutaka
sample report: samples/submission.json

Quick start

Download the latest binary from GitHub
- Linux (GNU): sudo curl -o /usr/local/bin/stackmuncher -L https://github.com/stackmuncher/stm_app/releases/download/v0.1.7/stackmuncher-x86_64-unknown-linux-gnu && sudo chmod 755 /usr/local/bin/stackmuncher
- Linux (MUSL): sudo curl -o /usr/local/bin/stackmuncher -L https://github.com/stackmuncher/stm_app/releases/download/v0.1.7/stackmuncher-x86_64-unknown-linux-musl && sudo chmod 755 /usr/local/bin/stackmuncher
- macOS: sudo curl -o /usr/local/bin/stackmuncher -L https://github.com/stackmuncher/stm_app/releases/download/v0.1.7/stackmuncher-x86_64-apple-darwin && sudo chmod 755 /usr/local/bin/stackmuncher
- Windows: invoke-webrequest -uri https://github.com/stackmuncher/stm_app/releases/download/v0.1.7/stackmuncher-x86_64-pc-windows-msvc.exe -outfile $env:windir\stackmuncher.exe
Change the current directory to one of your projects with a Git repository (has .git subfolder) and run:
- Linux: stackmuncher
- Windows PowerShell: stackmuncher

The app will access the local Git repository for the current directory and create a stack report, but will NOT submit any data to the Directory to let you review the stack report first. It will start updating your profile on subsequent runs unless --dryrun flag is used.

Example

I made commits to ~/rust/xml_to_serde project recently and now want to test StackMuncher app on it:

~$ cd rust/xml_to_serde
~/rust/xml_to_serde$ stackmuncher
   Summary (LoC/libs):  Rust 1265/6, Markdown 187, Bash 16
   Stack reports:       /home/mx/stackmuncher/reports/home_ubuntu_rust_xml_to_serde_git_9a32520d
   Project added to:    https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK

Adding more commit emails

We often commit to the same repo using different user.email Git setting. Run git shortlog -s -e --all to check if you made commits under any other email addresses.

Example

Find out what email addresses were used in commits to xml_to_serde repo:

~/rust/xml_to_serde$ git shortlog -s -e --all
     8  Alex Trump <...>
     5  Martin Crump <...>
     3  alex trump <...>
     1  mx <[email protected]>
    31  rimutaka <[email protected]>

mx and rimutaka are the same person. Let's add both emails to StackMuncher config using --email parameter:

~/$ stackmuncher config --emails "[email protected], [email protected]"

    Primary email: [email protected]
    Commit emails: [email protected], [email protected]

    Anonymous profile: https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK
    Public profile: disabled
    GitHub validation: not set

    Stack reports: /home/mx/stackmuncher/reports/
    Config folder: /home/mx/stackmuncher/config/
    Executable:    /usr/local/bin/stackmuncher

The app stored two emails from --emails param in its config file and printed its full config info (config command). From now on it will look for commits from [email protected] and [email protected].

Adding more projects to your profile

Adding more of your projects to your Directory Profile builds a more complete picture of your skills. StackMuncher can be configured to keep your profile current as you write and commit more code:

Make sure stackmuncher executable is placed in a folder included in PATH environment variable or add its folder to PATH.

Check if you have Git hooks already configured: git config --get-all init.templatedir

if the query returned a value - edit your post-commit templates manually
if the query returned nothing - add a post-commit Git hook:

Shell

git config --global --add init.templatedir '~/.git-templates'
mkdir -p ~/.git-templates/hooks
echo 'stackmuncher --log info 2>&1 >> ~/.stm.log' >> ~/.git-templates/hooks/post-commit
chmod a+x ~/.git-templates/hooks/post-commit

PowerShell

git config --global --add init.templatedir '~/.git-templates'
mkdir -p ~/.git-templates/hooks
echo '#!/bin/sh' >> ~/.git-templates/hooks/post-commit
echo 'stackmuncher --log info 2>&1 >> ~/.stm.log' >> ~/.git-templates/hooks/post-commit

Run git init on your existing repos to add the hook from the template.
- Any new repos or clones will get the hook added by default.
- Repos with an existing hooks/post-commit file can have the hook added with echo 'stackmuncher --log info 2>&1 >> ~/.stm.log' >> .git/hooks/post-commit. Run it from the root of the project folder.

Git will invoke the app every time you make a commit to a repo with the post-commit hook to generate a report, log its progress in ~/.stm.log and update your Directory Profile.

You can skip adding the Git hook and run stackmuncher from the root of any of your projects. No additional params are required.

Making your profile public

Anonymous profiles are identified by a public key from the key-pair generated by the app on the first run. E.g. https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK The profile can be viewed by anyone with the link, but it cannot be discovered otherwise.

Public profiles are searchable by employers looking for software developers. Your public profile will be created with the same login and personal details as your GitHub profile.

E.g. https://stackmuncher.com/rimutaka has contact details and public projects from https://github.com/rimutaka as well as private projects from https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK.

Run stackmuncher github
Use the signature it printed for a private Gist to confirm your GitHub account ownership
Run stackmuncher config --gist [URL of the Gist]

Using StackMuncher app on multiple machines

Download stackmuncher executable to a 2nd machine
Run stackmuncher config on both machines to see the location of config folders
Copy-paste the contents of .stm_config/config.json and .stm_config/key.txt from the 1st to the 2nd machine

The 2nd machine will be connected to the same Developer Profile as the first one for as long as they share the same key.txt and config.json files. If you loose the key file the app will generate a new one and create a new Developer Profile. Contact us on [email protected] to merge the old profile into the new one.

Detailed usage instructions

Running stackmuncher without any additional params generates a report for the project in the current working directory and updates your Developer Profile.

Some of the app's settings are cached in a local config file and only need to be set once. You can set, change or unset them via CLI params or by editing config.json file directly.

Processing settings

--emails "[email protected],[email protected]" : a list of your email addresses used in commits to to be analyzed. Defaults to git config user.email. Run git shortlog -s -e --all to check if you made commits under other email addresses. Set once.
--project "path_to_project_to_be_analyzed": an optional relative or absolute path to the project/repo to analyze, defaults to the current working directory.
--dryrun: tells the app to generate a report, save it locally, but not upload anything to the Directory.

Example:

~$ stackmuncher --project "~/rust/stm_server" --emails "[email protected], [email protected]" --dryrun

   Summary (LoC/libs):  Rust 12656/26, Markdown 587, PowerShell 169
   Stack reports:       /home/mx/stackmuncher/reports/home_ubuntu_rust_stm_server_a8ff58d9
   Profile update:      skipped with `--dryrun` flag

Profile settings

--primary_email "[email protected]": an optional email address for Directory notifications only. Defaults to git config user.email. Set once.

Example:

~$ stackmuncher config --primary_email "[email protected]"

    Primary email: [email protected]
    Commit emails: [email protected], [email protected]

    Anonymous profile: https://stackmuncher.com/?dev=9PdHabyyhf4KhHAE1SqdpnbAZEXTHhpkermwfPQcLeFK
    Public profile: https://stackmuncher.com/rimutaka
    GitHub validation: https://gist.github.com/rimutaka/fb8fc0f87ee78231f064131022c8154a

    Stack reports: /home/mx/stackmuncher/reports/
    Config folder: /home/mx/stackmuncher/config/
    Executable:    /usr/local/bin/stackmuncher

Debug settings

--log error|warn|info|debug|trace: the log is written to stdout. Defaults to error for least verbose output. Redirect the output to a file or null device to completely silence it. E.g. stackmuncher --log debug >> ~/stm_trace.log
--reports "path to reports folder": a path to an alternative location for saving stack reports. The path can be relative or absolute. Defaults to a platform-specific user-data location. Set once.
--config "path to config folder": a path to an alternative location of the config folder. The path can be relative or absolute. Defaults to a platform-specific user-data location.

Additional info

stackmuncher help: displays usage info.
stackmuncher config: display the contents of the config file and its location. The config file can be edited manually.

Limitations

The current version of the app is at alpha-stage and should be used for testing purposes only.

Only a small number of computer languages are recognized.
The app may unintentionally include private library names in the report - do not use it on commercially-sensitive projects.
The only way to delete a profile is to email [email protected].
It may take up to 2 minutes for a profile to be created/updated after a report submission.
Very large reports (over 50MB) are likely to be rejected.
Repositories with more than 10,000 files are not processed.

Troubleshooting

We want to hear about as many issues users run into as possible. Copy-paste the log and error messages printed by the app into https://github.com/stackmuncher/stm_app/issues/new/choose and let us help you.

Pre-requisites:

Git is installed and its user.email setting was configured
the project to be analyzed has commits from the same author/committer as in user.email setting

If the app did something, but no report was submitted:

look through the log it printed for clues
run stackmuncher config and check the output in reports folder - there should be at least 4 files:
- project_report.json: includes all contributors
- combined_report.json: a combined report for authors/committers from Git's user.email setting or from --emails param
- submission.json: a sanitized version of the combined report exactly as it is submitted to the Directory
- contributor_xxxxxxxx.json: cached reports for individual contributors

Building from source

Assuming that you have Git and a Rust toolchain installed, just clone the repo and run the app:

git clone https://github.com/stackmuncher/stm_app.git
cd stm_app
cargo run -- --log error --project "path_to_any_of_your_local_projects"
