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 allows the user to quickly obtain a list of the latest entries without requesting each subscribed feed individually.
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
| Platform | Locations |
| --- | --- |
| Linux | $XDG_CONFIG_HOME/syndicationd/config.toml
$HOME/.config/syndicationd/config.toml
|
| macOS | $HOME/Library/Application Support/syndicationd/config.toml
|
|Windows | {FOLDERID_RoamingAppData}/syndicationd/config.toml

Synd does not automatically create configuration files.
When creating a configuration file, you can use the following command
synd config init > config.toml

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 syndicationd requires is user:email
(Github) or email
(Google) to authenticate the user's email address. 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

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
.
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
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, forhttps://example.ymgyt.io
, it would behttps://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, specifyhttps://github.com/ymgyt/syndicationd/releases.atom
- For tags, it's
https://github.com/ymgyt/syndicationd/tag.atom
- To obtain releases of a repository, specify
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, forhttps://www.reddit.com/r/HelixEditor/
, it would behttps://www.reddit.com/r/HelixEditor.rss
If you're looking for feeds, here are my recommendations.
