`kish` - a simple shell, aspiring to be fully POSIX-compatibile in the future

Syntax highlighting	Interactive history

What currently works:

simple commands
quoting
redirections (> file)
piping (command1 | command2)
conditional execution: && and ||
compound commands ({ command1; command2 } | command3)
builitins:
- true
- false
- cd (without -P and -L)
- source
if statements: if <command-list>; then <command-list>; [else <command-list>]; fi
while and until loops
for loops
piping and redirecting to/from bulitins/command lists/if statements
user defined variables
special variables:
- return value from last command - $?
- current pid - $$
inline environment variables (HOME='/' command)
$() command substitution
basic interactive syntax highlighting
history saved in ~/.kish_history
interactive history lookup ala fish (but with up to 4 simultaneous search results)
loading ~/.kishrc

The kish shell depends on tcbrindle/span and AmokHuginnsson/replxx. Those dependencies can be pulled from git submodules:

$ git submodule update --init

$ cmake .
$ make

The kish shell can be tested by a shell script located in test/tests.sh. Simply run the shellscript with a path to built kish as its argument.
