Welcome to ciigo

ciigo is a library and a program to write static web server with embedded files using AsciiDoc and Markdown markup format.

As showcase, the following websites are build using ciigo,

ciigo as CLI

ciigo as CLI can convert, generate, and/or serve a directory that contains markup files, as HTML files.

Usage

ciigo [-template <file>] [-exclude <regex>] convert <dir>

Scan the "dir" recursively to find markup files (.adoc or .md) and convert them into HTML files. The template "file" is optional, default to embedded HTML template.

ciigo [-template <file>] [-exclude <regex>] [-out <file>] \
	[-package-name <string>] [-var-name <string>] \
	embed <dir>

Convert all markup files inside directory "dir" recursively and then embed them into ".go" source file. The output file is optional, default to "ciigo_static.go" in current directory. The package name default to main. The variable name default to memFS.

ciigo help

Print the usage.

ciigo [-template <file>]  [-exclude <regex>] [-address <ip:port>] \
    serve <dir>

Serve all files inside directory "dir" using HTTP server, watch changes on markup files and convert them to HTML files automatically. If the address is not set, its default to ":8080".

ciigo version

Print the current ciigo version.

ciigo as library

This section describe step by step instructions on how to build and create pages to be viewed for local development using ciigo.

First, clone the ciigo repository. Let says that we have cloned the ciigo repository into $HOME/go/src/git.sr.ht/~shulhan/ciigo.

Create new Go repository for building a website. For example, in directory $HOME/go/src/remote.tld/user/mysite. Replace "remote.tld/user/mysite" with your private or public repository.

$ mkdir -p $HOME/go/src/remote.tld/user/mysite
$ cd $HOME/go/src/remote.tld/user/mysite

Initialize the Go module,

$ go mod init remote.tld/user/mysite

Create directories for storing our content and a package binary.

$ mkdir -p cmd/mysite
$ mkdir -p _contents

Copy the example of stylesheet and HTML template from ciigo repository,

$ cp $HOME/go/src/git.sr.ht/~shulhan/ciigo/_example/index.css ./_contents/
$ cp $HOME/go/src/git.sr.ht/~shulhan/ciigo/_example/html.tmpl ./_contents/

Create the main Go code inside cmd/mysite,

package main

import (
	"git.sr.ht/~shulhan/ciigo"
	"git.sr.ht/~shulhan/pakakeh.go/lib/memfs"
)

var mysiteFS *memfs.MemFS

func main() {
	opts := &ciigo.ServeOptions{
		ConvertOptions: ciigo.ConvertOptions{
			Root: "_contents",
			HtmlTemplate: "_contents/html.tmpl",
		},
		Address: ":8080",
		Mfs: mysiteFS,
	}
	err := ciigo.Serve(opts)
	if err != nil {
		log.Fatal(err)
	}
}

Create a new markup file index.adoc inside the "_contents" directory. Each directory, or sub directory, should have index.adoc to be able to accessed by browser,

=  Test

Hello, world!

Now run the ./cmd/mysite with DEBUG environment variable set to non-zero,

$ DEBUG=1 go run ./cmd/mysite

Any non zero value on DEBUG environment signal the running program to watch changes in ".adoc" files inside "_contents" directory and serve the generated HTML directly.

Open the web browser at localhost:8080 to view the generated HTML. You should see "Hello, world!" as the main page.

Thats it!

Create or update any ".adoc" files inside "_contents" directory, the program will automatically generated the HTML file. Refresh the web browser to load the new generated file.

Deployment

First, we need to make sure that all markup files inside "_contents" are converted to HTML and embed it into the static Go code.

Create another Go source code, lets save it in internal/generate.go with the following content,

package main

import (
	"log"

	"git.sr.ht/~shulhan/ciigo"
)

func main() {
	opts := &ciigo.EmbedOptions{
		ConvertOptions: ciigo.ConvertOptions{
			Root:           "_contents",
			HtmlTemplate:   "_contents/html.tmpl",
		},
		EmbedOptions: memfs.EmbedOptions{
			PackageName: "main",
			VarName:     "mysiteFS",
			GoFileName:  "cmd/mysite/static.go",
		},
	}
	err := ciigo.GoEmbed(opts)
	if err != nil {
		log.Fatal(err)
	}
}

And then run,

$ go run ./internal

The above command will generate Go source code cmd/mysite/static.go that embed all files inside the "_contents" directory.

Second, build the web server that serve static contents in static.go,

$ go build cmd/mysite

Third, test the web server by running the program and opening localhost:8080 on web browser,

$ ./mysite

Finally, deploy the program to your server.

NOTE: By default, server will listen on address 0.0.0.0 at port 8080. If you need to use another port, you can change it at cmd/mysite/main.go.

That's it!
