  • Inline small functions at first pass
  • Dynamic optimization
    • inline captures
    • branch prediction?

      • C functions
      • closures
  • Merge sequential unpacks (if applicable)
  • Smaller instructions
  • Delay lambda constructors (when used conditionaly)

Examples

  • basics
  • merge-sort

Build and installation

Build and install with CMake.
Debug and Release build types are supported.

To build Release configuration do

  • create directory for temporary files:
    $ mkdir build
  • run CMake to generate build-scripts:
    $ cmake -D CMAKE_BUILD_TYPE=Release  # we want Release-configuration         -D CMAKE_INSTALL_PREFIX=<where-to-install>          -B build                     # temporary directory for a build         -S .                          # path to Ether sources
  • build and install (we are using GNU Make here):
    $ make -C build install
  • additionaly you can run some tests:
    $ make -C build test 
  • now you can add Ether to your system environment:
    $ prefix=<full-path-to-installation-directory> $ export PATH=$prefix/bin:path $ export PKG_CONFIG_PATH=${PKG_CONFIG_PATH:+${PKG_CONFIG_PATH}:}$prefix/lib/pkgconfig

    or you can use env.sh to setup environment in current shell:

    $ source env.sh <path-to-installation>

REPL

To run Ether in interactive mode just run it straightaway:

$ ether Ether REPL version: 0.2.0 build: Release build flags:  -Wall -Werror -Wextra -Wno-unused -Wno-error=cpp -rdynamic -O3 -DNDEBUG prefix: /home/pidhii/sandbox/create/ether/Release/install  Enter <C-d> (EOF) to exit Commands:   '.'                   to reset input buffer (cancel current expression)   '.help'               show help and available commands   '.help <ident>'       show help for given identifier   '.complete-empty'     display all available identifiers when completing empty word   '.no-complete-empty'  disable effect of the previous command  > 

Note that some syntacticly valid expressions will not work for REPL. It is due to “machanisms” of REPL are different to those applied to script processing.

Syntax higlighting

As you may have noticed, ether syntax is wery similar to ML’s one, so generaly you can just set your editor to treat it like OCaml for examle. However there are differences, and some of ether-only expressions tend to appear very often in the code (e.g. if let <pattern>).

Vim

I’m maintaining native syntax configuration only for Vim (not familiar with other editors). See ether-vim for the plugin. You can install with pathogen.

To make Vim recognise ether scripts you can add following line to your .vimrc:

autocmd BufRead,BufNewFile *.eth set filetype=ether syntax=ether

If you use NERDCommenter you can also add:

let g:NERDCustomDelimiters = {    'ether': { 'left': '--', 'leftAlt': '--[[', 'rightAlt': ']]', 'nested': 1 }    }

Where to get help

Enter REPL and try:

.help [<module-path>.]<variable> 

FAQ

Just joking =)
