Gemini GMI to HTML

IMPORTANT NOTE: the development of this tool evolved to GemPress and moved to sr.ht. Find fresh sources at: git.sr.ht/~aprates/gempress

This is a framework to streamline the process of writing contents as a Gemini Capsule, while making it also available as a common website, for a broader audience.

It's a combination of bash/sugar-c utilities to assist publishing to both worlds - Gemini and HTTP(S) - from the command line, including a "CI-like" script for sr.ht.

At it's core, there's a very simple text/gemini to text/html conversion tool, written in just about 150 lines of code, using C scripting with Sugar-C (tcc flavour).

Sugar-C compiles C code on the fly 'as if' a scripting language out of the box and leans on <sugar.h> library as only import for doing text file procedures.

See also: solderpunk's gemini spec, section 1.3.5 for text/gemini format reference.

Install

With Sugar-C (recommended)

First install Sugar-C from the GitHub repository, like:

git clone https://github.com/antonioprates/sugar.git
cd sugar
./install.sh

Note: you might have to use sudo ./install.sh depending on your user permissions.

Then, just clone this repo:

git clone https://github.com/antonioprates/gmi-to-html.git

Now you should be good to go!

Without Sugar-C

Alternatively, you can get the latest binary.

Then, get the bash scripts by cloning this repo, as explained in previous section.

Copy the binary into src folder and update capsule-to-website.sh to use the binary instead:

< sugar gmi-to-html.c $filePaths
---
> gmi-to-html $filePaths

Note: the binary is for x86_64 linux platform, yet you should be able build from source, by including sugar.h to the project.

Features

Format conversion

These are the markup conversions currently supported by gmi-to-html.c (the core tool):

• &, <, >, html escaped codes
• => internal links, converts path to *.html
• => external links, keeps original URL
• # heading , also sets the page title
• ## sub-heading
• ### sub-sub-heading
• * list item
• > blockquote
• --- horizontal rule
• pre-formatted block enclosed in triple backtick (```)
• inline code enclosed in backtick (`)
• inline bold words enclosed in asterisks (**)

Limitations

Inline formatting of code and bold expects a blank space before the opening markup and a blank space after the closing markup.

You can't pre-pend or append those immediately with punctuation .,:;!?. When writing your markdown you can overcome this limitation by adding an extra blank space.

Conveniences

Append footer

You can add text/gemini markdown contents to src/template/footer.gmi and all your pages will be automatically appended when using full-automatic publish script. Or check on src/append-footer.sh for manual usage

Theming

There is a simple style.css included under src/template folder. It is provided as a dark-blue theme and can be edited to tweak the outputted website look and feel.

Favicon

Also, there is a space capsule icon sample, designed by smalllikeart and made freely available from flaticon, converted with favicon.io.

Usage

First, on the command line cd into gmi-to-html/src folder, and then you have three options:

1. Manual operation

This method is mostly intended for testing purpose. Just provide a list of file paths as arguments to gmi-to-html.c script - run like:

sugar gmi-to-html.c ~/gemini/index.gmi ~/gemini/foo/bar.gmi

The .html files will be placed in the same path of the .gmi input files (use with care).

2. Semi-automatic

Optionally, you can use the capsule-to-website.sh to convert an entire Gemini Capsule folder in one go, also copying the styles.css and favicon.ico to the right places for you.

Recommended usage - provide path to you capsule folder (without the final slash), like:

./capsule-to-website.sh ~/gemini

Then, you get a pure HTML Website clone under ./website folder.

Note: the script will overwrite ./website folder, so it's not recommended to edit HTML output. Rather the best solution would be to tweak the scripts and contribute to this project, submitting a pull request, if you like.

3. Full-automatic (with SourceHut)

Finally, there is a 'CI like' (lol) script to publish to SourceHut Pages. Navigate to gemini://srht.site for the information on how to get hosted on SourceHut.

Configure: edit the publish-to-srht.sh to add your token and send_url configurations.

Provide capsule folder (without the final slash), like:

./publish-to-srht.sh ~/gemini

Note: the bash scripts, internally calls the C script with the list of files for you, so it assumes you have Sugar-C configured in your system.
