Run Vivaldi Package (rpm, deb or recompressed contents)

README.md

Run Vivaldi Package

The attached script (rvp.sh) will allow you to directly run a Vivaldi .deb or .rpm package without “installing” it. This works by quickly extracting the package contents into /var/tmp and then executing the binary therein (the extracted files are removed when you close Vivaldi).

Vivaldi is run with a temporary user data (settings) that are specific to that exact version. This is to avoid messing up the main install's user data.

To run Vivaldi in this way, make rvp.sh executable and start a build like so:

./rvp.sh vivaldi-snapshot-1.15.1159.7-1.x86_64.rpm

If no package name is provided, then the script will use the most recently updated Vivaldi package it can find in the current working directory.

Caching extracted packages

If you use the same build often you can avoid the need to keep re-extracting stuff by running it like so:

./rvp.sh --cache-build vivaldi-snapshot-1.15.1159.7-1.x86_64.rpm

The next time you run the build the pre-extracted copy will be used, making the startup time the same as an installed build.

Passing Vivaldi command line arguments

You can also pass all the normal, Vivaldi supported command line arguments after the package name. For example, to tell Vivaldi (1.15.1159.7) to start with a curl user agent, you could issue:

./rvp.sh vivaldi-snapshot-1.15.1159.7-1.x86_64.rpm --user-agent="curl/7.59.0"

Advanced options

Run the script with the --help switch to what other options are available.

Vivaldi Package Re-Compress

I also provide a secondary (helper) script vprc.sh (Vivaldi Package Re-Compress), which allows you to convert a normal package into another compression type that extracts faster. This gives you some of the benefit of caching but with less wasted disk space.

For example, the command (below) would convert the rpm to a Zstandard compressed cpio archive (vivaldi-snapshot-1.15.1159.7-1.x86_64.cpio.zst), which will only be a little larger and can typically decompress in less than a 10th of the time.

./vprc.sh vivaldi-snapshot-1.15.1159.7-1.x86_64.rpm zst

Note: You will need to install Zstandard to use this option. Other compression options include Brotli (br), gzip (gz), lzop (lzo), lz4 and bzip2 (via the super fast lbzip2)

To use such a compressed file just issue:

./rvp.sh vivaldi-snapshot-1.15.1159.7-1.x86_64.cpio.zst

rvp.sh

#!/bin/sh
# A script to directly run a Vivaldi .rpm or .deb package without
# installation. User data will be stored in a version numbered
# temp directory

# Use the most recent Vivaldi package in the current working
# directory or whatever the user has defined as the first option
# to this script.

# Provide some help on the available options.
helptext() {
  cat << HELP

Usage: `basename "$0"` [option(s)] [packagename] [vivaldi options]

If no packagename is provided, then the script will use the most recently
updated Vivaldi package it can find in the current working directory.

Normal options:

 -h, --help              (Show this help text and exit)
 -c, --cache-build       (Cache build - Avoids re-extraction for each run)
 -d, --default-user-data (Use the normal User Data directory)

Cleanup options:

 --clear-cached-build    (Remove the extracted/cached build and exit)
 --clear-build-user-data (Remove the per build User Data and exit)

It might be interesting to add "--user-data-dir="$HOME/.config/vivaldi-snapshot"" as a single flag to the script.

Yeah good point. I had considered this, but not gotten around to it yet since I figured it might be only me using it anyway. But sure, why not do something like this? Also since I know the stream I could have that be either "$HOME/.config/vivaldi" or "$HOME/.config/vivaldi-snapshot" as is appropriate. I'll add a switch (when I'm next in the office). Perhaps --default-user-data plus a short form (-d) that does the same (maybe also for a variable for those who want it to be the normal behaviour).

I should probably update this for anyone reading to say, I added that

I added support for more distros/kernel configurations. Previously this command could not work for most users on distros like Arch Linux because thier kernel if compiled to not support user namespaces by default. These are needed to sandbox Chromium correctly

Now I check for user namespace support and if it is not present I use the root, SUID sandbox of any installed Vivaldi, Chrome or Chromium I find instead.

I also tweaked the extraction commands to make them more robust after discovering that GNU cpio is not installed by default on the Antergos Linux live media, meaning that I could not use it to unpack a Vivaldi rpm package. Now I first look for bsdtar and use that instead, if present.
