source

cargo install --git https://github.com/ymgyt/syndicationd/ synd-term

[!NOTE] synd requires Nerd Fonts to be installed on your system for rendering icons.

Overview

The subscribed feeds are stored in synd-api. synd-api periodically fetches the feeds to retrieve the latest entries.
When the user views the feed list in synd, it retrieves the latest entries from synd-api's cache.
This project hosts the synd-api, but it can also be self-hosted.

Configuration

Settings can be configured in the following ways(in order of priority)

• Command line flag
• Environment variables
• Configuration file
• Default value

The location of the configuration file can be specified using --config or the environment variable SYND_CONFIG_FILE.
By default, synd will search the following locations depending on the platform

synd does not automatically create configuration files.
When creating a configuration file, you can use the following command

synd config init > config.toml

Settings

Additional categories

To add a category , add the following content to the configuration file

[categories.rust]
icon = { symbol = "🦀", color = { rgb = 0xF74C00 } }
aliases = ["rs"]

Authentication

Syndicationd maintains state (such as subscribed feeds) on the backend, and therefore requires authentication to make requests.
Currently, GitHub and Google are supported as authorize server/id provider.
The only scope required by syndicationd to authenticate users is the email address. please refer to the table below for details on the scopes for each provider.

[!IMPORTANT] The user's email address is used only as an identifier after being hashed and never stored.

for more info, please refer to the privacy policy

If you'd like support for additional ID providers, please feel free to request it.

Keymap

GitHub Notification

for more details, refer to keymap/default.rs

Subscribe feed

To subscribe a feed, type "Tab" to move to Feeds tab and then press "a".
synd uses edit to launch the user's editor(like a git commit).
The feed to subscribe to should be entered in the format:
Requirement Category URL

When you close the editor, the subscription request is sent to the API.

Requirement

Requirement indicates the importance of the feed.
This uses an analogy to RFC2119 and can take one of the following values:

• MUST: Most important, must be read.
• SHOULD: Next in importance, should be read unless there is a special reason not to.
• MAY: Lowest importance, may be read.

Category

Category represents the category of the feed. You can specify any value as a category. The values that synd recognizes as categories are defined in categories.toml. Default values and additional categories can be added from the configuration file.

Edit subscribed feed

To change the requirement or category of a feed you have already subscribed to, select the target feed in the Feeds tab and then press "e".

Unsubscribe feed

To unsubscribe from a feed, select the target feed and press "d".

Filter feeds/entries

Feeds and entries can be filtered as follows.

By requirement

To filter bases on the specified requirement, press "h/l(Left/Right)".
If you set the filter to MUST, only those marked as MUST will be displayed. Setting it to SHOULD will display feeds and entries marked as MUST and SHOULD. If set to MAY, all feeds and entries will be displayed.

By categories

To filter bases on categories, presess "c". This will display a label with keys to control the activation/deactivation of each category, allowing you to toggle the visibility of categories.
Pressing "-" will deactivate all categories, and pressing "+" will activate all categories.

You can exit the filter category mode by pressing the "Esc" key.
The icons for categories can be specified in categories.toml

Open feed entry

To open a feed entry in a web browser, select the entry and press Enter.
To view the entry in a text browser within the terminal, press the Space.
The command that is triggered by pressing the Space can be specified using the $SYND_BROWSER environment variable, or through related flags or configuration files.
The command is executed as $SYND_BROWSER $SYND_BROWSER_ARGS <entry url>.

Export subscribed feeds

To export subscribed feeds, execute the synd export command.
You can check the JSON schema of the data to be exported with synd export --print-schema

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Export",
  "type": "object",
  "required": [
    "feeds"
  ],
  "properties": {
    "feeds": {
      "type": "array",
      "items": {
        "$ref": "#/definitions/ExportedFeed"
      }
    }
  },
  "definitions": {
    "ExportedFeed": {
      "type": "object",
      "required": [
        "url"
      ],
      "properties": {
        "title": {
          "type": [
            "string",
            "null"
          ]
        },
        "url": {
          "type": "string"
        }
      }
    }
  }
}

Import feeds

You can subscribe to multiple feeds at once using the synd import command.
The input schema is the same as that of synd export. You can also check it with synd import --print-schema.

# from stdin
echo '{"feeds": [ {"url": "https://this-week-in-rust.org/atom.xml", "category": "rust", "requirement": "Must" } ]}' 
| synd import -

# read from file
synd export > feeds.json
synd import feeds.json

GitHub Notifications

To enable GitHub notifications feature, specify the --enable-github-notification | -G flag or set the environment variable SYND_ENABLE_GH=true.
When enabling the GitHub notifications feature, GitHub personal access token (PAT) is required. Specify the PAT using the --github-pat flag or the environment variable SYND_GH_PAT.

[!TIP] For GitHub notifications, unlike feeds, the synd-api is not used.

PAT Scope

Classic token

The repo scope is required. For more details, see about github notifications.

Fine grained access token

"Metadata" repository permissions (read) and "Notifications" user permissions (read) are required.
For more details, see list notifications for the authenticated user.
Since the Mark notification as done API does not support fine grained access token, classic token is required to use this feature.

Log

The default log file path is based on ProjectDirs::data_dir().
Please refer to the synd check command for the output destination.

You can modify the log directives using the environment variable SYND_LOG. (for example, SYND_LOG=synd=debug)

Theme

The theme can be changed using the --theme flag. Please refer to the help for the values that can be specified.

Backend api

By default, synd use https://api.syndicationd.ymgyt.io as the backend api(hosted on my home Raspberry Pi).
To change the endpoint, specify the --endpoint flag

The hosted api is instrumented with OpenTelemetry. Basic signals(traces,metrics,logs) are published on the public Grafana dashboard
Dashboards are managed with terraform

Remove cache and logs

Authentication credentials are cached. to remove them, execute synd clean.

Check application status

synd check [--format (human|json)] return current application status.

synd check

Feed tips

Some tips about feed that I know.

• Add openrss.org/ to the beginning of the URL to get its RSS feed. for example, for https://example.ymgyt.io, it would be https://openrss.org/example.ymgyt.io

• You can retrieve various updates as feeds on GitHub.

  • To obtain releases of a repository, specify releases.atom. for example, to obtain releases of syndicationd, specify https://github.com/ymgyt/syndicationd/releases.atom
  • For tags, it's https://github.com/ymgyt/syndicationd/tag.atom

• crates.io have introduced a couple of experimental RSS feeds

• Adding .rss to the end of a Reddit URL allows you to retrieve the feed. for example, for https://www.reddit.com/r/HelixEditor/, it would be https://www.reddit.com/r/HelixEditor.rss
