# GitHub Flavored Markdown Editor and Preview for TextMate2

Write and preview your Markdown files like a Boss! This bundle battle tested
under **M1**, **M2**, **M3** and **M4** Mac Books :) Yes, TextMate still
works on **Sequoia**!

## Requirements

Ruby is shipped with macOS. Current builtin ruby version (*macOS Sonoma*) is
**2.6.10**, and **2.6.10p210** (*macOS Sequoia*). It’s better to use `rbenv`
and set your `TM_RUBY` environment variable from TextMate!

```bash
rbenv which ruby
# /Users/vigo/.rbenv/versions/3.3.6/bin/ruby
```

If you have already installed `rbenv` or `rvm`, you’re good to go.

## Install and Update

Make sure that TextMate is not running. Add `TM_RUBY` environment variable to
TextMate:

```bash
$ defaults write com.macromates.TextMate environmentVariables \
    -array-add "{enabled = 1; value = \"$(rbenv which ruby)\"; name = \"TM_RUBY\"; }"
```

Now clone the repo:

```bash
$ cd ~/Library/Application\ Support/TextMate/Bundles/
$ git clone https://github.com/vigo/textmate2-gfm-preview.git GFM-Preview.tmbundle
$ cd GFM-Preview.tmbundle/Support/
$ bundle config set --local path 'vendor/bundle'
$ bundle
```

That’s it! Bundle installed successfully! You can follow updates via `git
pull` time-to-time.

```bash
$ cd ~/Library/Application\ Support/TextMate/Bundles/GFM-Preview.tmbundle
$ git pull origin main
```

## TextMate Environment Variables

You can define;

- `TM_GFM_ZOOM_FACTOR`: For zooming text.
- `TM_MARKDOWN_MATHJAX`: For Mathjax support.
- `TM_MARKDOWN_MERMAID`: For [Mermaid](https://mermaid-js.github.io/mermaid) support. (new!)
- `TM_GFM_FONT`: For custom font which is installed to your `~/Fonts`
- `TM_GFM_LINK_FONT_WEIGHT`: Optional `font-weight:` css directive for `a` link tags.
- `TM_GFM_LINK_TEXT_DECORATION`: Optional `text-decoration:` css directive for `a` link tags.

variables from *TextMate > Preferences > Variables* for customizing extra
features. Or do it from shell:

```bash
# assuming that, `OpenSans` font already installed on your ~/Library/Fonts

defaults write com.macromates.TextMate environmentVariables -array-add \
    '{enabled = 1; value = "100%"; name = "TM_GFM_ZOOM_FACTOR"; }' \
    '{enabled = 1; value = 1; name = "TM_MARKDOWN_MATHJAX"; }' \
    '{enabled = 1; value = 1; name = "TM_MARKDOWN_MERMAID"; }' \
    '{enabled = 1; value = "OpenSans"; name = "TM_GFM_FONT"; }' \
    '{enabled = 1; value = "500"; name = "TM_GFM_LINK_FONT_WEIGHT"; }' \
    '{enabled = 1; value = "underline"; name = "TM_GFM_LINK_TEXT_DECORATION"; }'
```

`kntrl + alt + cmd + p`

## Editor Features

With the power or Redcarpet and Rouge gems, we have some special features in
markdown operation!

<kbd>⌃</kbd> + <kbd>H</kbd> | Convert selection to highlighted text.

## Features

### Mermaid Support (new!)

        checkout develop
        commit
        commit
        checkout main
        merge develop
        commit
        commit
    ```

        Alice->>John: Hello John, how are you?
        John-->>Alice: Great!

    ```

Mermaid related configuration via env-vars:

- `TM_MARKDOWN_MERMAID_SHOW_SEQUENCE_NUMBERS`: `true` or `false` will
  (dis)allow sequence numbers on screen. (sequenceDiagram). Default value is
  `false`
