fix: update Pulse scripts for v4 Go rewrite support

[rcourtman]

✍️ Description

Updates Pulse installation scripts to support v4, which is a complete rewrite in Go. The current scripts attempt to install v4 as a Node.js application, resulting in broken installations.

What this fixes:

• Pulse v4 is now downloaded as a universal package (not Node.js)
• Uses the built-in installer script included with v4
• Preserves data directory during updates
• Removes Node.js dependencies for v4 installations

Why this is critical:

• Pulse v4.0.0 is already released
• Current scripts create broken installations for all new users
• v4 offers 87% less memory usage and 3x faster startup

why do you execute an shellscript inside an shell? All of this are functions build in by us.

• setup_go
• fetch_and_deploy_gh_release "pulse" "rcourtman/Pulse" "prebuild" "latest" "/opt/pulse" "*-linux-amd64.tar.gz"

the whole thing is done in 5 lines

Edit: setup_go not needed, its an prebuild.
its just an one-liner script

fetch_and_deploy_gh_release "pulse" "rcourtman/Pulse" "prebuild" "latest" "/opt/pulse" "*-linux-amd64.tar.gz"
and create service part

There, fixed it for ya @rcourtman :), you should do the same for the ct script

[rcourtman]

Thanks for the feedback @MickLesk! I've updated the PR to use the helper functions as requested:

✅ Now uses fetch_and_deploy_gh_release
✅ Added architecture detection to support ARM systems (amd64, arm64, armv7)
✅ Simplified to minimal code using your built-in functions
✅ Service creation follows the standard pattern

The script now properly handles all architectures that Pulse supports while using your helper functions.

Quick update needed: The environment variable should be PULSE_DATA_DIR not PULSE_CONFIG_DIR. Just pushed v4.0.3 which clarifies the data directory structure - everything goes in one directory (config + runtime data).

For the helper script, just change:

-Environment="PULSE_CONFIG_DIR=/etc/pulse"
+Environment="PULSE_DATA_DIR=/etc/pulse"

This ensures Pulse knows where to store its data. The default is /etc/pulse anyway, but being explicit is good.

[rcourtman]

Fixed! Changed to PULSE_DATA_DIR=/etc/pulse in commit c1821a6

[rcourtman]

@CrazyWolf13 pushed an update with the version file creation in ~/.pulse

To clarify on your questions:

• ARM detection was removed in earlier commits (Proxmox is x86-only)
• Update functionality is still there - the update_script function works the same way, just uses fetch_and_deploy_gh_release now
• Version file now follows the standard ~/.pulse pattern
• ENV file not needed - Pulse v4 uses a single data directory (defaults to /etc/pulse)

[rcourtman]

hey @MickLesk @CrazyWolf13 - thanks for the quick merge and feedback on this

noticed the docs site at https://community-scripts.github.io/ProxmoxVE/scripts?id=pulse still shows old v3 info. needs updating:

• Port: 7655 (not 3000)
• Remove "Create Proxmox-API-Token first" link - uses username/password through UI
• Config location: remove "/opt/pulse/.env" - doesn't use .env files, everything configured through web UI
• Built with: Go (not Node.js if mentioned elsewhere)

where does the site pull this info from? couldn't find it in the repo. happy to update it if you point me to the right place

its your cache, at my system are 4.0.3. but the json can be fixed in next time
