Supporting Libraries

Below is a list of all currently known libraries which implement VariPass interaction into various platforms.

VariPass Library for ESP8266 and ESP32 | GitHub

A library which allows easy VariPass reading and writing on the ESP8266 microcontroller.

VariPass Library for the OpenComputers Minecraft mod | GitHub

A library for the OpenComputers Minecraft mod which allows easy VariPass reading and writing from the computers added by the mod.

Changelog

v1.5.4 2021-02-21 - Graph re-reversal

• All graphing features have been re-reversed, both on the Dashboard and through the API when calling graph and sgraph actions. However, the reversal has been done properly unlike before and the Y axis is now on the right side. It is more natural to read data from left to right, and having the axis on the right side helps with readability too.
• API section has been renamed to "Docs".
• The Docs section's Demo API Client now shows a copyable GET URL for easier testing and experimentation purposes.

v1.5.3 2020-07-28 - Graph thickness

• The graph action now supports the optional thick parameter. Setting the parameter to true will make the graph appear thicker. Bold font will be used and all lines will use a thickness of 2 instead of 1. This option is useful for displaying large graphs on e-ink displays.
• Default line thickness on graphs generated with the graph action is now thinner (down to 1).
• Fixed an issue where requesting a graph on multiple devices at the same time may result in mixed up graphs.

v1.5.2 2020-07-24 - E-ink compatible graphs

• The graph action now supports the optional eink parameter. Setting the parameter to true will make the graph more compatible with e-ink displays. Namely, the returned image will be in BMP format with 1 bit depth (monochrome), background will be white, all graphics will be black and a bitmap font will be used.
• All returned graphs now have a correctly set Content-Length header.
• Changed conversion to BMP format making it faster.

v1.5.1 2020-07-17 - Graph image formats

• The graph action now supports the optional format parameter. This parameter specifies the image format which will be returned. Supported formats are png, jpg (or jpeg), gif or bmp. When no parameter is specified, the returned format is png.
• Added error_invalid_format result, returned when the format parameter is incorrect.
• All graphs now save with the filename graph.<format>.
• Added sgraph action. Works similar to graph, but returns a string result instead of a JSON in case of an error.

v1.5.0 2020-07-09 - Public variables

• Variables can now be made public. A public variable may be read in various ways, but may not be written to. These variables also don't require an API key to access so they may be safely sent to other people for viewing. More info on the API section.
• Removed error_missing_key response, as removing a key now switches to public API.

v1.4.0 2020-07-09 - Graph rendering API

• Added graph action to the API. This action will return a rendered graph of a certain variable as a PNG image. Perfect for retrieving on low powered devices and screens for displaying. Please consult the API section for indepth details.
• Reversed the direction of graphs on the Dashboard. We are not sure why have we ever designed them to go "backwards".
• A boolean variable on cooldown will now be more responsive on the Dashboard.

v1.3.0 2019-12-07 - Latest data actions

• Added latest and slatest actions to the API. These actions are similar to the all action, but return only the newest values of all variables. The second action is the simplified version similar to the sread action.
• Reordered actions in the Demo API Client at the bottom of the API Documentation page to follow the order like in the docs themselves.
• Added library list to the About page.

v1.2.2 2019-05-12 - Various fixes

• Both the create API action and the create button on Dashboard should work again. Oops.
• Fixed the demonstrative API client on the bottom of the API documentation page.
• Added more loading animations for various actions on the Dashboard.

v1.2.1 2019-05-02 - Min/Max values

• Added the min parameter to all variables. The default value has been set to 0 for already existing variables.
• Setting min and max values to different values to each other will engage special rendering of the Dashboard graph for that variable, clamping it between the two values. Both values now accept float values and may be negative.
• The min and max values can be set either when creating a variable using create, editing using edit or directly on the Dashboard in the edit menu of a variable under "Max Value" and "Min Value" parameters.

v1.2.0 2019-04-19 - Variable ordering

• Variables may now be re-ordered on the Dashboard using the new small arrows added to the top left of each variable.
• Added ordprev and ordnext actions to the API. These actions may be used to programatically change the order of the variables. Please refer to the documentation for info on how to use them.
• The variables of the float type may now be displayed with more than two decimals on the Dashboard.
• Updated the loading animation upon saving on the Dashboard to better reflect the waiting period between saves.

v1.1.1 2019-03-23 - Minor changes

• The variable boxes on the Dashboard will no longer awkwardly stack if the boxes are small enough.

v1.1.0 2019-01-21 - Boolean variable toggle actions

• Added toggle and stoggle actions to the API. These actions allow toggling a boolean variable's value. Please refer to the documentation for info on how to use them.

v1.0.2 2018-10-11 - Graphing improvements

• When setting the maximum variable value to a value other than 0, the graph will now be clamped between 0 and the maximum value.

v1.0.1 2017-02-12 - Minor fixes

• Fixed an issue where sread and swrite actions wouldn't use the correct result format in some situations.

v1.0.0 2017-02-08 - Initial release

• Initial release of the website.
