# xdg-open-ng
|
||||
# Syndicate utils
|
||||
|
||||
An `xdg-open` replacement that uses Syndicate and PCRE pattern matching to open URIs.
|
||||
## Syndesizer
|
||||
|
||||
There are two utilites, `xdg-open` and `uri_runner`. The former connects to a shared Syndicate dataspace via a UNIX socket at `$SYNDICATE_SOCK` otherwise `$XDG_RUNTIME_DIR/dataspace` and as has no other configuration. The `uri_runner` component is intended to be managed by the [Syndicate server](https://git.syndicate-lang.org/syndicate-lang/syndicate-rs) thru which it receives configuration, see [uri_runner.pr](./uri_runner.pr) as an example.
|
||||
A Syndicate multitool that includes a number of different actors that become active via configuration.
|
||||
|
||||
The [protocol.nim](./src/protocol.nim) file is generated from the [protocol.prs](./protocol.prs) schema, a [Tupfile](https://gittup.org/tup/) file is provided to do this.
|
||||
Think of it as a Busybox for Syndicate, if Busybox was created before POSIX.
|
||||
|
||||
## TODO
|
||||
- Fallback commands?
|
||||
Whether you use a single instance for many protocols or many specialized instances is up to you.
|
||||
|
||||
### Cache
|
||||
|
||||
Observes patterns and reässert the values captured for a given lifetime. Takes the argument `<cache { dataspace: #!any lifetime: float }>`. The lifetime of a cache counts down from moment a value is asserted.
|
||||
|
||||
Example configuration:
|
||||
```
|
||||
? <nixspace ?nixspace> [
|
||||
; Require the nix_actor during observations.
|
||||
?nixspace> ? <Observe <rec eval _> _> [
|
||||
$config <require-service <daemon nix_actor>> ]
|
||||
?nixspace> ? <Observe <rec realise _> _> [
|
||||
$config <require-service <daemon nix_actor>> ]
|
||||
|
||||
; Cache anything captured by observers in the $nixspace for an hour.
|
||||
; The nix_actor is not required during caching.
|
||||
$config <require-service <daemon syndesizer>>
|
||||
$config ? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <cache { dataspace: $nixspace lifetime: 3600.0 }> ]
|
||||
]
|
||||
```
|
||||
|
||||
### File System Usage
|
||||
|
||||
Summarize the size of file-system directory. Equivalent to `du -s -b`.
|
||||
Query the size of a directory in bytes by observing `<file-system-usage "/SOME/PATH" ?size>`.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
|
||||
? <exposed-dataspace ?ds> [
|
||||
|
||||
<require-service <daemon syndesizer>>
|
||||
? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <file-system-usage { dataspace: $ds }>
|
||||
]
|
||||
|
||||
]
|
||||
```
|
||||
|
||||
### HTTP driver
|
||||
|
||||
Experimental HTTP server that services requests using [some version](https://git.syndicate-lang.org/syndicate-lang/syndicate-protocols/src/commit/9864ce0ec86fb2f916c2aab318a1e6994ab8834c/schemas/http.prs) of the http Syndicate protocol schema.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
|
||||
let ?not-found = dataspace
|
||||
$not-found ? <request _ ?res> [
|
||||
$res ! <status 503 "Service unavailable">
|
||||
$res ! <done "No binding here.">
|
||||
]
|
||||
|
||||
let ?greeting = dataspace
|
||||
$greeting ? <request _ ?res> [
|
||||
$res ! <status 200 "ok">
|
||||
$res ! <chunk "Hello world">
|
||||
$res ! <done "!">
|
||||
]
|
||||
|
||||
let ?http = dataspace
|
||||
$http [
|
||||
<http-bind #f 80 get [ ] $not-found>
|
||||
<http-bind #f 80 get [|...|] $not-found>
|
||||
<http-bind #f 80 get ["hello"] $greeting>
|
||||
]
|
||||
|
||||
? <service-object <daemon http-driver> ?cap> [
|
||||
$cap <http-driver { dataspace: $http }>
|
||||
]
|
||||
|
||||
<daemon http-driver {
|
||||
argv: [ "/bin/syndesizer" ]
|
||||
clearEnv: #t
|
||||
protocol: application/syndicate
|
||||
}>
|
||||
|
||||
<require-service <daemon http-driver>>
|
||||
```
|
||||
|
||||
### JSON Socket Translator
|
||||
|
||||
Communicate with sockets that send and receive lines of JSON using `<send …>` and `<recv …>` messages.
|
||||
|
||||
Do not send messages into the dataspace configure with `<json-socket-translator …>` until `<connected @socketPath string>` is asserted.
|
||||
|
||||
```
|
||||
# MPV configuration example
|
||||
<require-service <daemon mpv-server>>
|
||||
|
||||
<daemon mpv-server {
|
||||
argv: [
|
||||
"/run/current-system/sw/bin/mpv"
|
||||
"--really-quiet"
|
||||
"--idle=yes"
|
||||
"--no-audio-display"
|
||||
"--input-ipc-server=/run/user/1000/mpv.sock"
|
||||
"--volume=75"
|
||||
]
|
||||
protocol: none
|
||||
}>
|
||||
|
||||
let ?mpvSpace = dataspace
|
||||
|
||||
? <service-state <daemon mpv-server> ready> [
|
||||
<require-service <daemon syndesizer>>
|
||||
? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <json-socket-translator {
|
||||
dataspace: $mpvSpace
|
||||
socket: <unix "/run/user/1000/mpv.sock">
|
||||
}>
|
||||
]
|
||||
]
|
||||
|
||||
$mpvSpace [
|
||||
|
||||
# announce the dataspace when the translator is connected
|
||||
? <connected $socketPath> [
|
||||
$config <mpv $mpvSpace>
|
||||
$config <bind <ref { oid: "mpv" key: #x"" }> $mpvSpace #f>
|
||||
]
|
||||
|
||||
# translate <play-file …> to an MPV command
|
||||
?? <play-file ?file> [
|
||||
! <send { "command": ["loadfile" $file "append-play"] }>
|
||||
]
|
||||
|
||||
# clear the playlist on idle so it doesn't grow indefinitely
|
||||
?? <recv {"event": "idle"}> [
|
||||
! <send { "command": ["playlist-clear"] }>
|
||||
]
|
||||
]
|
||||
```
|
||||
|
||||
### JSON Stdio Translator
|
||||
|
||||
Executes a command, parses its JSON output, converts to record `<recv @jsonData any>`, and publishes and messages it to a dataspace.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
<require-service <daemon syndesizer>>
|
||||
|
||||
let ?ds = dataspace
|
||||
<bind <ref {oid: "syndicate" key: #x""}> $ds #f>
|
||||
|
||||
? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <json-stdio-translator {
|
||||
argv: [
|
||||
"yt-dlp"
|
||||
"--dump-json"
|
||||
"https://youtu.be/RR9GkEXDvog"
|
||||
]
|
||||
dataspace: $ds
|
||||
}>
|
||||
]
|
||||
```
|
||||
|
||||
### Pulse proxy
|
||||
|
||||
A proxy actor that passes assertions and messages to a configured capability but only asserts observations on a a periodic pulse.
|
||||
This can be used to implement polling behavior.
|
||||
|
||||
```
|
||||
# Example config
|
||||
let ?ds = dataspace
|
||||
|
||||
<require-service <daemon syndesizer>>
|
||||
? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <pulse {dataspace: $ds}>
|
||||
]
|
||||
|
||||
$ds ? <pulse 3600.0 ?proxy> [
|
||||
$proxy ? <assertion-updated-hourly ?value> [
|
||||
$log ! <log "-" {assertion-updated-hourly: $value}>
|
||||
]
|
||||
]
|
||||
```
|
||||
|
||||
### SQLite
|
||||
|
||||
Readonly access to SQLite databases. Asserts rows as records in response to SQL query assertions. Dynamic updates are not implemented.
|
||||
|
||||
Can be disabled by passing `--define:withSqlite=no` to the Nim compiler.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
<require-service <daemon syndesizer>>
|
||||
|
||||
let ?sqlspace = dataspace
|
||||
|
||||
? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <sqlite {
|
||||
dataspace: $sqlspace
|
||||
database: "/var/db/example.db"
|
||||
}>
|
||||
]
|
||||
|
||||
let ?tuplespace = dataspace
|
||||
|
||||
$sqlspace <query "SELECT id, name FROM stuff" $tuplespace>
|
||||
|
||||
$tuplespace [
|
||||
? [?id ?name] [
|
||||
$log ! <log "-" { row: <example-row $id $name> }>
|
||||
]
|
||||
? <sqlite-error ?msg ?ctx> [
|
||||
$log ! <log "-" { msg: $msg ctx: $ctx }>
|
||||
]
|
||||
]
|
||||
```
|
||||
|
||||
### XML translator
|
||||
|
||||
Translates between Preserves and XML according to the [Conventions for Common Data Types](https://preserves.dev/conventions.html).
|
||||
|
||||
Examples:
|
||||
- `<xml-translation "<foo a=\"1\"> <bar>hello world!</bar></foo>" <foo {"a": 1}<bar "hello world!">>>`
|
||||
- `<xml-translation "" [#t #f]>`
|
||||
- `<xml-translation "<<</>>" #f>`
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
? <sharedspace ?ds> [
|
||||
$ds ? <Observe <rec xml-translation _> _> $config [
|
||||
$config <require-service <daemon syndesizer>>
|
||||
$config ? <service-object <daemon syndesizer> ?cap> [
|
||||
$cap <xml-translator { dataspace: $ds }>
|
||||
]
|
||||
]
|
||||
]
|
||||
```
|
||||

## esc_printer_actor
|
||||
|
||||
A basic [ESC/P](https://en.wikipedia.org/wiki/ESC/P) printer controller.
|
||||
|
||||
Takes a path to a printer device file as a command line argument and publishes a `<printer @cap #:any @device-path string>` to its environment.
|
||||
The capability in this assertion is an entity that prints the strings it receives as messages.
|
||||
While the `<bold>` or `<italic>` is asserted to this entity the printer will go into the corresponding font mode (if the printer supports it).
|
||||
|
||||
Sample Syndicate server script:
|
||||
```
|
||||
<require-service <daemon printer>>
|
||||
|
||||
? <printer ?printer> [
|
||||
$log ?? <log "-" { line: ?line }> [
|
||||
$printer ! $text
|
||||
$printer ! "\r\n"
|
||||
# Print log messages.
|
||||
]
|
||||
]
|
||||
|
||||
|
||||
? <service-object <daemon printer> ?cap> [
|
||||
$cap ? <printer ?printer ?device> [
|
||||
$config <printer $printer>
|
||||
]
|
||||
]
|
||||
|
||||
<daemon printer {
|
||||
argv: [ "/bin/esc_printer_actor" "/dev/usb/lp0"]
|
||||
protocol: application/syndicate
|
||||
}>
|
||||
```
|
||||
|
||||
## http_client
|
||||
|
||||
The inverse of `http-driver`.
|
||||
|
||||
### Caveats
|
||||
- HTTPS is assumed unless the request is to port 80.
|
||||
- If the request or response sets `Content-Type` to `application/json` or `…/preserves`
|
||||
the body will be a parsed Preserves value.
|
||||
- No cache support.
|
||||
- Internal errors propagate using a `400 Internal client error` response.
|
||||
|
||||
Sample Syndicate server script:
|
||||
```
|
||||
# A top-level dataspace
|
||||
let ?ds = dataspace
|
||||
|
||||
# A dataspace for handling the HTTP response.
|
||||
let ?response = dataspace
|
||||
$response [
|
||||
?? <done { "code": "EUR" "exchange_middle": ?middle } > [
|
||||
$ds <exchange EUR RSD $middle>
|
||||
]
|
||||
]
|
||||
|
||||
$ds [
|
||||
<request
|
||||
# Request Euro to Dinar exchange rate.
|
||||
<http-request 0 "kurs.resenje.org" 443
|
||||
get ["api" "v1" "currencies" "eur" "rates" "today"]
|
||||
{Content-Type: "application/json"} {} #f
|
||||
>
|
||||
$response
|
||||
>
|
||||
|
||||
# Log all assertions.
|
||||
? ?any [
|
||||
$log ! <log "-" { assertion: $any }>
|
||||
]
|
||||
]
|
||||
|
||||
? <service-object <daemon http-client> ?cap> [
|
||||
$cap <http-client {
|
||||
dataspace: $ds
|
||||
}>
|
||||
]
|
||||
|
||||
<require-service <daemon http-client>>
|
||||
|
||||
? <built http-client ?path ?sum> [
|
||||
<daemon http-client {

|
||||
protocol: application/syndicate
|
||||
}>
|
||||
]
|
||||
```
|
||||
|
||||
## mintsturdyref
|
||||
|
||||
A utility for minting [Sturdyrefs](https://synit.org/book/operation/builtin/gatekeeper.html#sturdyrefs).
|
||||
|
||||
## mount_actor
|
||||
|
||||
Actor for mounting filesystems on Linux.
|
||||
|
||||
Sample Syndicate server script:
|
||||
```
|
||||
# Assert a file-system we want to mount.
|
||||
<mount "/dev/sda3" "/boot" "vfat">
|
||||
|
||||
# Transform mount assertions into mount status observations.
|
||||
? <mount ?source ?target ?fs> [
|
||||
? <mount $source $target $fs _> [ ]
|
||||
]
|
||||
|
||||
# Assert mounting succeded.
|
||||
? <mount _ ?target _ #t> [
|
||||
<service-state <mountpoint $target> ready>
|
||||
]
|
||||
# Assert mount failed.
|
||||
? <mount _ ?target _ <failure _>> [
|
||||
<service-state <mountpoint $target> failed>
|
||||
]
|
||||
|
||||
# Assert the details into the machine dataspace.
|
||||
? <machine-dataspace ?machine> [
|
||||
$config ? <mount ?source ?target ?fs ?status> [
|
||||
$machine <mount $source $target $fs $status>
|
||||
]
|
||||
]
|
||||
|
||||
# Require the mount_actor daemon.
|
||||
<require-service <daemon mount_actor>>
|
||||
<daemon mount_actor {
|
||||
argv: ["/home/emery/src/bin/mount_actor"]
|
||||
protocol: application/syndicate
|
||||
}>
|
||||
|
||||
# Pass the daemon the config dataspace.
|
||||
? <service-object <daemon mount_actor> ?cap> [
|
||||
$cap { dataspace: $config }
|
||||
]
|
||||
```
|
||||
|
||||
## msg
|
||||
|
||||
A utility that parses its command-line arguments as Preserves and send them as messages to `$SYNDICATE_ROUTE`.
|
||||
When called as `assert` (by a symlink or a rename) it will make assertions instead.
|
||||
|
||||
## PostgreSQL
|
||||
|
||||
Readonly access to PostgreSQL databases. Asserts rows as records in response to SQL query assertions. Dynamic updates are not implemented.
|
||||
|
||||
Can be disabled by passing `--define:withPostgre=no` to the Nim compiler.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
<require-service <daemon postgre_actor>>
|
||||
|
||||
let ?sqlspace = dataspace
|
||||
|
||||
? <service-object <daemon postgre_actor> ?cap> [
|
||||
$cap <postgre {
|
||||
dataspace: $sqlspace
|
||||
connection: [
|
||||
["host" "example.com"]
|
||||
["dbname" "foobar"]
|
||||
["user" "hackme"]
|
||||
]
|
||||
}>
|
||||
]
|
||||
|
||||
let ?tuplespace = dataspace
|
||||
|
||||
$sqlspace <query "SELECT id, name FROM stuff" $tuplespace>
|
||||
|
||||
$tuplespace ? [?id ?name] [
|
||||
$log ! <log "-" { row: <example-row $id $name> }>
|
||||
]
|
||||
```
|
||||
|
||||
## preserve_process_environment
|
||||
|
||||
This utility serializes it's process environment to Preserves and prints it to stdout.
|
||||
It can be used to feed the environment variables of a nested child of the Syndicate server back to the server. For example, to retreive the environmental variables that a desktop manager passed on to its children.
|
||||
|
||||
## SQLite
|
||||
|
||||
Readonly access to SQLite databases. Asserts rows as records in response to SQL query assertions. Dynamic updates are not implemented.
|
||||
|
||||
Can be disabled by passing `--define:withSqlite=no` to the Nim compiler.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
<require-service <daemon sqlite_actor>>
|
||||
|
||||
let ?sqlspace = dataspace
|
||||
|
||||
? <service-object <daemon sqlite_actor> ?cap> [
|
||||
$cap <sqlite {
|
||||
dataspace: $sqlspace
|
||||
database: "/var/db/example.db"
|
||||
}>
|
||||
]
|
||||
|
||||
let ?tuplespace = dataspace
|
||||
|
||||
$sqlspace <query "SELECT id, name FROM stuff" $tuplespace>
|
||||
|
||||
$tuplespace ? [?id ?name] [
|
||||
$log ! <log "-" { row: <example-row $id $name> }>
|
||||
]
|
||||
```
|
||||
|
||||
## syndump
|
||||
|
||||
Utility for printing assertions and messages. Parses the command-line arguments as a pattern, connects a dataspace via `$SYNDICATE_ROUTE`, and writes observations to standard-output. Published assertions are prefixed by the `+` character, retractions by `-`, and messages by `!`.
|
||||
|
||||
Example
|
||||
```sh
|
||||
# Print patterns in use, filter down with AWK to only the published patterns.
|
||||
$ FS=':' syndump '<Observe ? _>' | awk -F : '/^+/ { print $2 }'
|
||||
```
|
||||
|
||||
## XSLT processor
|
||||
|
||||
Perform XML stylesheet transformations. For a given textual XSLT stylesheet and a textual XML document generate an abstract XML document in Preserves form. Inputs may be XML text or paths to XML files.
|
||||
|
||||
```
|
||||
# Configuration example
|
||||
let ?ds = dataspace
|
||||
$ds [
|
||||
? <xslt-transform "/stylesheet.xls" "/doc.xml" ?output> [
|
||||
? <xml-translation ?text $output> [
|
||||
$log ! <log "-" { xslt-output: $text }>
|
||||
]
|

|
||||
|
||||
<require-service <daemon xslt_actor>>
|
||||
? <service-object <daemon xslt_actor> ?cap> $cap [
|
||||
<xml-translator { dataspace: $ds }>
