# Obsidian-Pseudocode
This is a plugin for [Obsidian](https://obsidian.md/) that allows you to render LaTeX-style pseudocode inside a code block. The plugin is based on [pseudocode.js](https://github.com/SaswatPadhi/pseudocode.js), a JavaScript library that typesets pseudocode beautifully to HTML.
## Features
- Intuitive grammar: The plugin takes a LaTeX-style input that supports the algorithmic constructs from LaTeX's algorithm packages. With or without LaTeX experience, a user should find the grammar fairly intuitive.
- Print quality: The HTML output produced by the plugin is (almost) identical with the pretty algorithms printed on publications that are typeset by LaTeX.
- Math formula support: Inserting math formulas in the pseudocode is as easy as LaTeX. Just enclose math expression in `$...$` or `\(...\)`.
### Future Features
- [ ] Syntax highlighting.
- [ ] Auto-completion inside `pcode` code block.
## Usage
To use the plugin, simply create a code block in your Obsidian note and add your pseudocode inside it. Then, add the language specifier `pcode` (short for "pseudocode") to the code block. The plugin will automatically render the pseudocode as LaTeX.
Here is an example:
```
```pcode
\begin{algorithm}
\caption{Quicksort}
\begin{algorithmic}
\PROCEDURE{Quicksort}{$A, p, r$}
\IF{$p < r$}
\STATE $q = $ \CALL{Partition}{$A, p, r$}
\STATE \CALL{Quicksort}{$A, p, q - 1$}
\STATE \CALL{Quicksort}{$A, q + 1, r$}
\ENDIF
\ENDPROCEDURE
\PROCEDURE{Partition}{$A, p, r$}
\STATE $x = A[r]$
\STATE $i = p - 1$
\FOR{$j = p$ \TO $r - 1$}
\IF{$A[j] < x$}
\STATE $i = i + 1$
\STATE exchange
$A[i]$ with $A[j]$
\ENDIF
\STATE exchange $A[i]$ with $A[r]$
\ENDFOR
\ENDPROCEDURE
\end{algorithmic}
\end{algorithm}
```
```

## Installation
To install the plugin, download the latest release from the [releases page](https://github.com/yourusername/obsidian-pseudocode/releases) and extract it to your Obsidian plugins folder. Then, enable the plugin in your Obsidian settings.
~~Or just download it within Obsidian's community plugins.~~ (Pending...)
