# Gemini
Applications and libraries for building applications on Gemini (see https://gemini.circumlunar.space/).
## Gemini CLI
### Run a server
```sh
gemini serve --domain=example.com --certFile=a.crt --keyFile=a.key --path=.
```
### Request content
curl for Gemini.
```sh
gemini request --insecure --verbose gemini://example.com/pass
```
## Gemini Server Docker image
### Run a server with Docker
```sh
docker run \
-v /path_to_your_cert_files:/certs \
-e PORT=1965 \
-e DOMAIN=localhost \
-v /path_to_your_content:/content \
-p 1965:1965 \
adrianhesketh/gemini:latest
```
## Quick start
Check out https://github.com/a-h/gemini/releases for the latest version of the `gemini` command line tool to run locally, or use Docker:
```sh
# Create a server certificate.
openssl ecparam -genkey -name secp384r1 -out server.key
openssl req -new -x509 -sha256 -key server.key -out server.crt -days 3650
# Make a Gemini file.
mkdir content
echo "# Hello, World!" > content/index.gmi
# Run the container.
docker pull adrianhesketh/gemini:latest
docker run -v `pwd`:/certs -e PORT=1965 -e DOMAIN=localhost -v `pwd`/content:/content -p 1965:1965 adrianhesketh/gemini:latest
```
## Libraries
### Serve
Use `gemini.Server` / `gemini.ListenAndServe` to build your own custom servers.
Supports hosting multiple Gemini servers on a single IP address.
These are used to build a Gemini application that supports dynamic content.
```go
package main
import (
"context"
"fmt"
"log"
"github.com/a-h/gemini"
"github.com/a-h/gemini/mux"
)
func main() {
// Create the handlers for a domain (a.gemini).
okHandler := gemini.HandlerFunc(func(w gemini.ResponseWriter, r *gemini.Request) {
w.Write([]byte("OK"))
})
helloHandler := gemini.HandlerFunc(func(w gemini.ResponseWriter, r *gemini.Request) {
w.Write([]byte("# Hello, user!\n"))
if r.Certificate.ID == "" {
w.Write([]byte("You're not authenticated"))
return
}
w.Write([]byte(fmt.Sprintf("Certificate: %v\n", r.Certificate.ID)))
})
// Create a router for gemini://a.gemini/require_cert and gemini://a.gemini/public
routerA := mux.NewMux()
// Let's make /require_cert require the client to be authenticated.
routerA.AddRoute("/require_cert", gemini.RequireCertificateHandler(helloHandler, nil))
routerA.AddRoute("/public", okHandler)
// Create a file system handler gemini://b.gemini/{path}
handlerB := gemini.FileSystemHandler(gemini.Dir("./content"))
// Set up the domain handlers.
ctx := context.Background()
a, err := gemini.NewDomainHandler("a.gemini", "a.crt", "a.key", routerA)
if err != nil {
log.Fatal("error creating domain handler A:", err)
}
b, err := gemini.NewDomainHandler("b.gemini", "b.crt", "b.key", handlerB)
if err != nil {
log.Fatal("error creating domain handler B:", err)
}
// Start the server for two domains (a.gemini / b.gemini).
err = gemini.ListenAndServe(ctx, ":1965", a, b)
if err != nil {
log.Fatal("error:", err)
}
}
```
### Route
Use `github.com/a-h/gemini/mux` to provide routing between Gemini handlers and extract variables from URL paths.
### Built-in utility handlers
* `RequireCertificateHandler` a handler that ensures that users present certificates.
* `FileSystemHandler` to support hosting static content.
### Gemini client
```go
client := gemini.NewClient()
// Make a request to the server without accepting its certificate.
r, certificates, authenticated, ok, err := client.Request("gemini://a.gemini/require_cert")
if err != nil {
log.Printf("Request failed: %v", err)
return
}
```
Configure allowed server certificates for trust-on-first-use certificate support:
```
client.AddAlllowedCertificateForHost("a.gemini", "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")
