It is with immense pleasure that I announce that version 0.5.1 off the harlock scripting language is out!

Here is the detailed release log, with a list the artifacts to install the language on debian-like systems, or directly a binary for the supported architectures.

Release note artifacts @github/Abathargh/harlock

Build from source

Notice that you can always compile and install harlock by executing:

go install github.com/Abathargh/harlock/cmd/harlock

or:

git clone https://github.com/Abathargh/harlock
make install

Release details

This v0.5.1 release is a bugfix one, that solidifies harlock usage within build pipelines.

The main issues that were tackled are:

• Correctly handling runtime and evaluation errors being raised at the top-level scope to trigger a non-zero error code. This led to silent errors being passed inside of pipelines using harlock.
• Drop support for go 1.15 unsupported targets.
• Adding previously missing .exe suffix for windows executable names when cross-compiling for windows on non-windows
• Minor fixes to .gitignore and Makefile.

Last couple of releases included a new error system which was thoroughly tested and fixing it is the main reason for v0.5.1.

Usage and new developments

I've been using harlock a lot to test the avr_io nim library that I work on, alongside personal projects where I need firmware to be updated over the wire/air with huge success.

A nice working project using the language can be found in the bootloader example for avr_io, where it is used to showcase the library capabilities when writing bootloaders for embedded applications.

I wrote an in-depth article on how to use harlock for these kind of scenarios on antima at the following link.
