The Toit Language

Add BLAKE2S crypto hash support. Start BLE services in one go. Improve BLE resource management. Add 'close' to the BLE adapter. Fix RMT on esp32s3 (and other variants). github.com/toitlang/toit/…

How to analyze an out-of-memory situation on an ESP32 running Toit. blog.toit.io/get-insight-in…

Add reader.do --lines [block]. Fix byte-array size checks in firmware-copy primitive. Fix subtle GC issues with TLS buffers. Fix toitdoc generation for packages. Fix yaml text starting with Q. Fix yaml indented blocks. Fix yaml implicit keys. github.com/toitlang/toit/…

Add 'toit pkg' and 'toit snapshot' commands. Don't use tasks to wait for services to appear. Handle 'werror' when doing 'toit.compile --analyze'. Stream JSON and YAML output onto a Writer. Change close-X to mark-closed on io.Reader and io.Writer. github.com/toitlang/toit/…

Introduce new io library. Optimize getting size of builtin collections. Avoid spinning up too many native threads on host platforms. Avoid lock contention on scavenge on host platforms. Start to bring back the toit executable. Roll esp-idf to latest v5.0. github.com/toitlang/toit/…

Compare the simple and wrong syntax with the correct but verbose syntax: a = [[]] * 4 b = [ [] for _ in range(4) ] In Toit you pass a block (small fn introduced with a colon) to the List constructor. c := List 4: []

Going to ban this space-less function call. We need this syntax for raw strings.

Took an immense amount of self discipline and focus, so yesterday ends(at 1am today) with an esp32 running a @toitlang container with capacitive moisture sensor sending moisture levels every 3 seconds to a local mqtt broker on a raspberry Pi which I can look at through my phone.

Looks like we picked the right day to have a PNG reader that's 100% written in a memory safe language. @v1.0.0" target="_blank" rel="nofollow noopener">pkg.toit.io/package/github…

On the device (an @m5stack).

New version of @toitlang's pixel_display library is getting sliders. We have PNG support, but no PNGs were used here, just gradients like the ones we know from the web.

Version v2.0.0-alpha 118 is released with support for weak maps and watchdog timers. github.com/toitlang/toit/…

Our friends from @toitlang have just released a new tutorial for Walter, our powerful ESP32-S3 development board with LTE-M, NB-IoT, and GNSS. docs.toit.io/tutorials/netw… Going to launch soon on @crowd_supply. 🙌crowdsupply.com/dptechnics/wal…💪 #Walter #IoT #Toit #IoTDevelopment

In the Toit weak map proposal the lifetime of the key is not relevant, so it can be a string or an int, but the value can be automatically removed from the map if it is not otherwise reachable and we need the memory.

Looks like I'm getting weak maps, but not with the JavaScript semantics. In JavaScript WeakMap the key keeps the value alive, but when the key is collected by the GC, the key-value pair are removed from the map, and the value may become GC-able.
