Heynote is a dedicated scratchpad for developers. It functions as a large persistent text buffer where you can write down anything you like. Works great for that Slack message you don't want to accidentally send, a JSON response from an API you're working with, notes from a meeting, your daily to-do list, etc.
The Heynote buffer is divided into blocks, and each block can have its own Language set (e.g. JavaScript, JSON, Markdown, etc.). This gives you syntax highlighting and lets you auto-format that JSON response.
Ctrl + A Select all text in a note block. Press again to select the whole buffer
Ctrl + Alt + Up/Down Add additional cursor above/below
Alt + Shift + F Format block content (works for JSON, JavaScript, HTML, CSS and Markdown)
Alt Show menu
```
## Download/Installation
Download the appropriate (Mac, Windows or Linux) version from [heynote.com](https://heynote.com). The Windows build is not signed, so you might see some scary warning (I can not justify paying a yearly fee for a certificate just to get rid of that).
Heynote's Math blocks are powered by [Math.js expressions](https://mathjs.org/docs/expressions). Checkout their [documentation](https://mathjs.org/docs/) to see what [syntax](https://mathjs.org/docs/expressions/syntax.html), [functions](https://mathjs.org/docs/reference/functions.html), and [constants](https://mathjs.org/docs/reference/constants.html) are available.
### Accessing the previous result
The variable `prev` can be used to access the previous result. For example:
```
128
prev * 2 # 256
```
### Changing how the results of Math blocks are formatted
You can define a custom `format` function within the Math block like this:
```
_format = format # store reference to the built in format
You can also do something like this to show the number with your default locale or provide a [custom one](https://www.w3.org/International/articles/language-tags/):
## The notes library (only for Heynote 2.0, not yet released)
The notes library is a directory (with sub dirs) on the disk with a `.txt` file for each note. It's created the first time you start Heynote, with the default note file `scratch.txt` in it. The default location for the library is:
You can change the path of the notes library in the settings. Heynote expects reasonably fast disk access to the notes library, so it's not recommended to use a network drive, though file syncing services like Dropbox, OneDrive, etc. should work (see below).
Heynote is built to support synchronizing the notes library (or buffer file in the case of Heynote 1.x) through file-syncing services like Dropbox, OneDrive, etc. However, note that the synchronization logic is quite simple, so editing the same note on two different machines at the same time might lead to conflicts and unexpected results.
When using a file synching service that support "offloading" of files in the cloud (removing them from the disk), it's recommended to mark the notes library as "always available offline".
It's been reported [(#48)](https://github.com/heyman/heynote/issues/48) that ChromeOS's Debian VM need the following packages installed to run the Heynote AppImage:
Due to [an issue in Electron](https://github.com/electron/electron/issues/38288), the global hotkey will not work in all applications running under Wayland. In KDE it is possible to work around this limitation by adding this Kwin script:
See the [KWin scripting tutorial](https://develop.kde.org/docs/plasma/kwin/) for instructions on how to install the script.
Remember to enable the script in the KDE System Settings. It may also be necessary to go into the KDE System Settings and bind the "Toggle Heynote" key manually.
