## UI Modes

You can switch Markdown themes from the bottom info bar.

Available modes:

- Read Mode: only the right preview pane
- Write Mode: only the left editor pane
- Preview Mode: edit and preview side by side
- Preview Mode S: editor and preview scrolling are synchronized (algorithm still being improved)
- Preview Mode N: editor and preview scroll independently

## Command Line

```bash
$ dmarked -h
Usage: dmarked [options] source [destination]

Options:
  -h, --help                Show this help.
  -v, --version             Show version information.
  -w, --write <file>        Open a markdown file in DMarked
  -f, --format <pdf>        Convert markdown files to pdf/html
  -L, --use-landscape       Set landscape orientation (default is portrait)
  -s, --page-size <A4>      Set page size, e.g. A4, Letter
  -l, --margin-left <10>    Set left margin (pt)
  -t, --margin-top <10>     Set top margin (pt)
  -r, --margin-right <10>   Set right margin (pt)
  -b, --margin-bottom <10>  Set bottom margin (pt)
  -d, --max-depth <1>       Max depth for batch conversion

Arguments:
  source                    Source file or directory
  [destination]             Output file or directory
```

The CLI mode was designed mainly for batch conversion, and that goal has mostly been achieved.

Convert `a.md` to `my.html`:

```bash
dmarked -f html a.md my.html
```

Convert all Markdown files in the current directory and up to 2 levels of subdirectories to PDF. The `-s` options are the same as in the GUI page-size selector. The theme follows the last-used GUI theme.

If `destination` is omitted, exported PDFs are placed alongside the source md files.

```bash
dmarked -f pdf -s A5 -t 20 -b 20 -d 3 .
```

Convert all md files in `content` (excluding subdirectories) to PDF and write them into `content_pdf`:

```bash
dmarked -f pdf content content_pdf
```
