# simplebookmarker
`simplebookmarker` provides the `sbm` command, which adds PDF bookmarks from an
indented plain-text table of contents.
## Installation
```console
cargo install simplebookmarker
```
## Usage
Given `book.pdf` and `book.txt`, run:
```console
sbm book
```
The result is written to `book_bm.pdf`.
Input, bookmark, and output paths can also be set explicitly:
```console
sbm --input source.pdf --bookmarks contents.txt --output result.pdf
```
Run `sbm --help` for all options.
## Bookmark format
Each valid line starts with a one-based PDF page number and a title. A hyphen
between the page number and title is optional. Indent child bookmarks with one
tab or four spaces per level.
```text
1-Introduction
3-Background
5-History
10 First chapter
```
Blank and malformed lines are ignored. Entries with page zero or a page number
beyond the end of the PDF are also ignored. If indentation skips a level, the
entry is attached at the deepest available level.
