Retrieves conversations from Slack to terminal.
Internal program structure allows to read conversations from other messaging services and write them to any destination.
Doesn't support threads (yet).
Build (working Rust toolchain needed) :
cargo build --release PATH=$PWD/target/release/:$PATH
Expose Slack token as environment variable (see below) :
export SLACK_TOKEN=
Get help :
rustractor --help
Examples :
rustractor public_channel:general rustractor private_channel:topsecret rustractor im:secret.lover rustractor mpim:mpdm-alice--bob
Export RUST_LOG=info environment variable to get informations about the program execution.
Create new app on https://api.slack.com/apps, with name Rustractor, and choose the workspace.
Get client ID & secret from the app page, store them in CLIENT_ID and CLIENT_SECRET environment variables.
Add https://postman-echo.com/get to the redirection URLs in the OAuth &
Permissions app page (or use an other HTTP target to access the code send by
Slack to the redirection URL).
Load this URL in a browser after adding the client ID at the end :
https://slack.com/oauth/v2/authorize?user_scope=channels:read,channels:history,groups:read,groups:history,im:read,im:history,mpim:read,mpim:history,users:read&redirect_uri=https%3A%2F%2Fpostman-echo.com%2Fget&client_id=
Store the returned code in the CLIENT_CODE environment variable.
Get Oauth token in the next 10 minutes :
curl -F code=$CLIENT_CODE -F client_id=$CLIENT_ID -F client_secret=$CLIENT_SECRET https://slack.com/api/oauth.v2.access
Store the returned token to the CLIENT_TOKEN environment variable, and backup it.
Example retrieving the channel list :
curl -H "Authorization: Bearer $CLIENT_TOKEN" https://slack.com/api/conversations.list
