Espruino 1v95 released!

I've just released Espruino 1v95, with a whole bunch of extra changes:

Regular Expressions

They're here - finally! On all official Espruino boards (and many others, if there's enough memory).

While it's not 100% full support, it's enough for the majority of things, with String.indexOf, String.split, RegExp.exec and crucially String.replace - even with the ability to specify a function as the replacement.

>"Hello world".replace(/l/g, function(match,idx) { return "[L"+idx+"]"; })
="He[L2][L6]o wor[L15]d"

Fast File IO

• Added E.setFlags({unsyncFiles:1} which doesn't sync the file to the SD card after each write - it's much faster
  
• Filesystem API now uses flat strings (avoiding the 512 byte copy for each call)
  
• Increase default internal SD card bitrate to 4MHz (from 100k) - eg the Original Espruino
  
  

Other Additions

• Added ES6 Object.assign
  
• Puck.js gets a bump in variables from 2000 to 2500
  
• NRF.setScan automatically decodes service and manufacturer data packets now
  
• NRF.findDevices aggregates multiple advertising packets from the same device if they contain different information.
  
• Add E.errorFlag event to allow JS to respond to internal errors
  
• ESP8266 can now use GPIO16
  
• ESP8266 and ESP32 now support UDP with dgram thanks to @opichals awesome work, and official Espruino boards will be able to support it for AT command devices (eg ESP8266/Espruino WiFi) when the libraries are updates
  
• The REPL now outputs non-numeric elements in arrays
  
• digitalWrite/Read will now call .read on an object if it is passed in. This means you can now use port expanders with most Espruino libraries!
  
• Added E.getAddressOffor super low-level work - you can get the actual address of the variable's data in RAM for things like DMA
  
• Manufacturer Data can now be specified with setAdvertising in Puck.js (and we have an official Puck.js manufacturer code - 0x0590)
  
• You can now overwrite Puck.js's memory protection with E.setFlags so you can write wherever you want
  
• E.HSBtoRGB can now output as [R,G,B] for neopixels.
  
  

Improvements

• nRF5x boards like Puck.js can now run UART reliably at 115200 baud, and will work connected to ESP8266 or GSM/GPRS
  
• Exception/error reporting is a bit tidier now
  
• We not use the Esc[J VT100 code when cycling through command history (much faster REPL on low bandwidth connections)
  
• JSON.stringify for arrays is faster
  
• Added support for negating pins in software (eg. buttons/LEDs), for boards like NRF52832DK
  
• Bluetooth LE events (specifically promise completions) now use the event queue - removing the dreaded MEMORY_BUSY message
  
  
  

Bugfixes

• Fix a memory leak in tab completion
  
• Commands that previously didn't work correctly with sparse arrays now do
  
• Fix a memory leak when allocating DataViews, which fixed a memory leak on BLE notifications
  
• net/http .listen now return the server instance (like node.js)
  
• Fixed lexing of '/*/' as a complete block comment
  
• E.HSBtoRGB to wraps 'hue' value properly
  
• Remove spikes when changing pin state using digitalWrite
  
• E.setBootCode() (without an empty string) now works
  
• Thanks to @JumJum and @Wilberforce ESP32 setWatch now works correctly
