Find opinions about a given phrase (also URL) on social news websites:
It can be used to include discussions on static websites/blogs.
opinions is a command-line replacement of discu.eu service. It directly calls search engines on underlying websites.
Application is developed with a security-first approach:
- functionality is limited by design
- access to the OS is restricted by application-level sandboxing.

Websites are queried with User-Agent: opinions/<version_number> (<os>; +https://github.com/macie/opinions).
opinions can be used to extend static websites with comments-like feature. You can search for active discussions about your article, filter out false positive results (eg. get only articles from your domain) and generate HTML links with standard Unix commands:
opinions 'Grug Brained' | grep 'grugbrain.dev' | awk -F '\t' '
BEGIN { print "<ul>" }
{ print " <li><a href=\""$2"\" title=\"["$1"] "$3"\">"$1"</a></li>" }
END { print "</ul>" }

You can also build it manually with commands: make && make build (or without
sandboxing: make && make unsafe).
Use make (GNU or BSD):
make- install dependenciesmake test- runs testmake e2e- runs e2e tests for CLImake check- static code analysismake build- compile binary from the latest commitmake unsafe- compile binary from the latest commit without the security sandboxmake dist- compile binaries from the latest commit for all supported OSesmake clean- removes compilation artifactsmake cli-release- tag the latest commit as a new release of CLImake module-release- tag the latest commit as a new release of Go modulemake info- print system info (useful for debugging).
At the begining, only CLI was released with semantic versioning scheme (commits marked by tags v1.0.0-v1.5.1).
Currently repo contains CLI and Go module which can be developed with different pace. Commits with versions are tagged with:
v2.X.X(semantic versioning) - versions of Go modulecli/vYYYY.0M.MICRO(calendar versioning) - versions of command-line utility.
On modern Linuxes and OpenBSD, CLI application has restricted access to kernel calls with seccomp and pledge.
- add sandboxing for FreeBSD (with Capsicum - see: https://reviews.freebsd.org/rS308432 and https://cgit.freebsd.org/src/tree/lib/libcapsicum/capsicum_helpers.h?id=d66f9c86fa3fd8d8f0a56ea96b03ca11f2fac1fb#n104))
- verify hardened version of linux arm and arm64.
Results depend on search engines of underlying social news websites. They may be different than expected.
