1 # Highlight code on a static html file 2 3 This program parses an html file and adds 4 [chroma](https://github.com/alecthomas/chroma) classes to code within pre and 5 code tags. Then you can add chroma themes with css. 6 7 ## Running 8 9 Make sure you have [golang](https://go.dev/) installed (if not follow this 10 [instructions](https://go.dev/doc/install))then run: 11 12 ```shell 13 $ go run main.go <test_file.html> 14 ``` 15 16 with `<test_file.html>` being an html file containing some code to highlight. 17 This is an example of a code snippet within an html file that this program 18 should add css classes 19 20 ```html 21 (...) 22 <pre><code class="language-c"> 23 #include <stdio.h> 24 25 int main(void) { 26 char *hw = "Hello, world!\n"; 27 28 printf("%s\n", hw); 29 return 0; 30 } 31 </code></pre> 32 (...) 33 ``` 34 35 But it uses regular expression so it should be easier to adapt to other formats. 36 37 ## Example 38 The main purpose of this program was to highlight code snippets on my blog. 39 Checkout [this post](https://kloeckner.com.ar/blog/testing-syntax-highlight/testing-syntax-highlight) 40 that I made to test it. 41 42 ## License 43 [MIT](https://opensource.org/licenses/MIT)
