# Goldsmith
|
|
|
|
Goldsmith is a fast and easily extensible static website generator written in Go. In contrast to many other generators,
|
|
Goldsmith does not force any design paradigms or file organization rules on the user, making it possible to generate
|
|
anything from blogs to image galleries using the same tool.
|
|
|
|
## Tutorial
|
|
|
|
Goldsmith does not use any configuration files, and all behavior customization happens in code. Goldsmith uses the
|
|
[builder pattern](https://en.wikipedia.org/wiki/Builder_pattern) to establish a chain, which modifies files as they pass
|
|
through it. Although the [Goldsmith](https://godoc.org/git.foosoft.net/alex/goldsmith) API is short and (hopefully) easy
|
|
to understand, it is often best to learn by example:
|
|
|
|
1. Start by copying files from a source directory to a destination directory (the simplest possible use case):
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
2. Now let's convert any Markdown files to HTML fragments (while still copying the rest), using the
|
|
[Markdown](https://godoc.org/git.foosoft.net/alex/goldsmith-components/plugins/markdown) plugin:
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
3. If we have any
|
|
[front matter](https://raw.githubusercontent.com/FooSoft/goldsmith-samples/master/basic/content/index.md) in our
|
|
Markdown files, we need to extract it using the,
|
|
[FrontMatter](https://godoc.org/git.foosoft.net/alex/goldsmith-components/plugins/frontmatter) plugin:
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(frontmatter.New()). // extract frontmatter and store it as metadata
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
4. Next, we should run our barebones HTML through a
|
|
[template](https://raw.githubusercontent.com/FooSoft/goldsmith-samples/master/basic/content/layouts/basic.gohtml) to
|
|
add elements like a header, footer, or a menu; for this we can use the
|
|
[Layout](https://godoc.org/git.foosoft.net/alex/goldsmith-components/plugins/frontmatter) plugin:
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(frontmatter.New()). // extract frontmatter and store it as metadata
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
Chain(layout.New()). // apply *.gohtml templates to *.html files
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
5. Now, let's [minify](https://en.wikipedia.org/wiki/Minification_(programming)) our files to reduce data transfer and
|
|
load times for our site's visitors using the
|
|
[Minify](https://godoc.org/git.foosoft.net/alex/goldsmith-components/plugins/minify) plugin:
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(frontmatter.New()). // extract frontmatter and store it as metadata
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
Chain(layout.New()). // apply *.gohtml templates to *.html files
|
|
Chain(minify.New()). // minify *.html, *.css, *.js, etc. files
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
6. Debugging problems in minified code can be tricky, so let's use the
|
|
[Condition](https://godoc.org/git.foosoft.net/alex/goldsmith-components/filters/condition) filter to make
|
|
minification occur only when we are ready for distribution.
|
|
|
|
```go
|
|
goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(frontmatter.New()). // extract frontmatter and store it as metadata
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
Chain(layout.New()). // apply *.gohtml templates to *.html files
|
|
FilterPush(condition.New(dist)). // push a dist-only conditional filter onto the stack
|
|
Chain(minify.New()). // minify *.html, *.css, *.js, etc. files
|
|
FilterPop(). // pop off the last filter pushed onto the stack
|
|
End(dstDir) // write files to dstDir
|
|
```
|
|
|
|
7. Now that we have all of our plugins chained up, let's look at a complete example which uses
|
|
[DevServer](https://godoc.org/git.foosoft.net/alex/goldsmith-components/devserver) to bootstrap a complete
|
|
development sever which automatically rebuilds the site whenever source files are updated.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"flag"
|
|
"log"
|
|
|
|
"git.foosoft.net/alex/goldsmith"
|
|
"git.foosoft.net/alex/goldsmith-components/devserver"
|
|
"git.foosoft.net/alex/goldsmith-components/filters/condition"
|
|
"git.foosoft.net/alex/goldsmith-components/plugins/frontmatter"
|
|
"git.foosoft.net/alex/goldsmith-components/plugins/layout"
|
|
"git.foosoft.net/alex/goldsmith-components/plugins/markdown"
|
|
"git.foosoft.net/alex/goldsmith-components/plugins/minify"
|
|
)
|
|
|
|
type builder struct {
|
|
dist bool
|
|
}
|
|
|
|
func (b *builder) Build(srcDir, dstDir, cacheDir string) {
|
|
errs := goldsmith.
|
|
Begin(srcDir). // read files from srcDir
|
|
Chain(frontmatter.New()). // extract frontmatter and store it as metadata
|
|
Chain(markdown.New()). // convert *.md files to *.html files
|
|
Chain(layout.New()). // apply *.gohtml templates to *.html files
|
|
FilterPush(condition.New(b.dist)). // push a dist-only conditional filter onto the stack
|
|
Chain(minify.New()). // minify *.html, *.css, *.js, etc. files
|
|
FilterPop(). // pop off the last filter pushed onto the stack
|
|
End(dstDir) // write files to dstDir
|
|
|
|
for _, err := range errs {
|
|
log.Print(err)
|
|
}
|
|
}
|
|
|
|
func main() {
|
|
port := flag.Int("port", 8080, "server port")
|
|
dist := flag.Bool("dist", false, "final dist mode")
|
|
flag.Parse()
|
|
|
|
devserver.DevServe(&builder{*dist}, *port, "content", "build", "cache")
|
|
}
|
|
```

## Samples
|
|
|
|
Below are some examples of Goldsmith usage which can used to base your site on:
|
|
|
|
* [Basic Sample](https://git.foosoft.net/alex/goldsmith-samples/src/branch/master/basic): a great starting point, this
