How to use template functions in Go language to dynamically generate PPT slides?
Slides are an important part of modern presentations, and their dynamic generation can greatly improve work efficiency and reusability. The Go language provides the function of template functions, which can easily realize the dynamic generation of PPT slides. This article will introduce how to use template functions in the Go language to achieve this function.
First, we need to create a template file for generating PPT slides. The template file can contain various elements of the slide, such as titles, text, pictures, etc. We can use the html/template package of the Go language to create template files.
The following is an example of a simple PPT slide template file, named "template.html":
<!DOCTYPE html>
<html>
<head>
<title>{{.Title}}</title>
</head>
<body>
{{range $slide := .Slides}}
<div class="slide">
<h2 id="slide-Title">{{$slide.Title}}</h2>
<p>{{$slide.Content}}</p>
<img src="/static/imghwm/default1.png" data-src="{{$slide.Image}}" class="lazy" alt="{{$slide.Title}}">
</div>
{{end}}
</body>
</html>In the above template file, we use the template syntax of the Go language. {{.Title}} means referencing the Title field in the data passed to the template, {{range $slide := .Slides}} means traversal transfer To the Slides field in the template's data, and assign the current slide to the $slide variable.
Next, we need to parse the template file and render the data in Go language. We can use the ParseFiles function in the html/template package to parse the template file, and the Execute function to render the data and generate the final HTML code.
The following is a sample code that uses template functions to generate PPT slides:
package main
import (
"html/template"
"os"
)
type Slide struct {
Title string
Content string
Image string
}
type Presentation struct {
Title string
Slides []Slide
}
func main() {
slides := []Slide{
{Title: "Slide 1", Content: "Content 1", Image: "image1.jpg"},
{Title: "Slide 2", Content: "Content 2", Image: "image2.jpg"},
{Title: "Slide 3", Content: "Content 3", Image: "image3.jpg"},
}
data := Presentation{
Title: "My Presentation",
Slides: slides,
}
tmpl, err := template.ParseFiles("template.html")
if err != nil {
panic(err)
}
f, err := os.Create("presentation.html")
if err != nil {
panic(err)
}
defer f.Close()
err = tmpl.Execute(f, data)
if err != nil {
panic(err)
}
}In the above sample code, we defined two structure types Slide and Presentation, respectively represents the slide and the entire PPT presentation. We create a slides slice containing the slide data and pass it to the Slides field of the Presentation structure.
We then use the template.ParseFiles function to parse the template file and the Execute function to render the template file and data to presentation.html in the file.
The final generated presentation.html file will dynamically generate the HTML code of the PPT slide based on the data. We can open the file using any modern web browser and display the PPT slideshow in the browser.
By using template functions in the Go language, we can easily generate dynamic PPT slides to achieve more efficient work and better scalability. Hope this article is helpful to you!

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
