# 2025-07-06 Update
## Featured Releases: July 6, 2025
### Updates to `cbor-book` - July 6, 2025
- Deployed new syntax highlighting throughout the book.
- Finished chapter on [basic use of the `dcbor` CLI](https://cborbook.com/part_2/dcbor_cli.html).
- Added chapter on [matching using the `dcbor` CLI](https://cborbook.com/part_2/dcbor_cli_matching.html).
- Use of the `dcbor` CLI will require another chapter on "Advanced Matching."
- Added stub chapter on [Introducing Gordian Envelope](https://cborbook.com/part_3/introducing_gordian_envelope.html) that right now just links to videos.
- Added stub chapter on [Matching using the `envelope` CLI](https://cborbook.com/part_3/envelope_cli.html) that right now just links to the `envelope` CLI documentation at GitHub.
- There will also eventually be a chapter on "Advanced Matching" for the `envelope` CLI.
- Added appendices for [dCBOR Patex Reference](https://cborbook.com/appendices/dcbor_patex.html) and [Envelope Patex Reference](https://cborbook.com/appendices/envelope_patex.html) that use full syntax highlighting.
### New Style for Command Line Examples - July 5, 2025
- All command line examples in the documentation for `dcbor-cli`, `bc-envelope-cli`, `seedtool-cli`, `provenance-mark-cli`, and `cbor-book` have been updated to use a consistent style:
```bash
input command 1
input command 2 \
line 2 continuation
│ output line 1
│ output line 2
│ output line 3
```
- Note the blank line between input and output, which is mandatory.
- If more than one input and output are in a single code block, then the first output must be followed by a blank line:
```bash
input line 1
│ output line 1
input line 2
│ output line 2
```
This new style:
- More clearly separates input from output,
- Improves readability and consistency across all command line examples,
- Makes it easier to copy and paste commands directly from the documentation.
- Makes it easier to rapidly test examples by use affordances like the built-in `Run Selected Text in Active Terminal` command in VS Code.
- Causes shell syntax highlighters to *not* highlight the output like it is command input.
Note that the `│` is `BOX DRAWINGS LIGHT VERTICAL` (U+2502) used in the new style is not the same as the vertical bar `|` `VERTICAL LINE` (U+007C) used in the command line. This is because many layout engines will render the box drawing character as a continuous vertical line, which is more visually appealing than the vertical bar character, which will always render vertical gaps.
The following keybindings can be added to VS code to faciliate the above workflows.
- The first binds `ctrl+enter` to the `Run Selected Text in Active Terminal`
- The second binds `cmd+alt+|` to typing `│ `. This is convenient when paired with `cmd+alt+↑` (Add cursor above) and `cmd+alt+↓` (Add cursor below) for doing multi-line editing, enabling examples to be formatted in the above style with just a few keystrokes.
```json
{
"key": "ctrl+enter",
"command": "workbench.action.terminal.runSelectedText",
"when": "editorTextFocus"
},
{
"key": "cmd+alt+\\",
"command": "type",
"when": "editorTextFocus",
"args": {
"text": "│ "
}
}
```
