Tips & tricks

The idea of this page is to list some useful code snippets. Please always indicate if it needs to use any specific plugin or oPack.

Variable checks

Checking if provided file exists

function doStuffWithFiles(aFile) {
   aFile = _$(aFile)
           .isString("The aFile argument provided needs to be a string.")
           .check(io.fileExists, "The provided aFile doesn't exist.")
           .$_("You need to provide aFile.");

   ...
}

OpenAF-console

Increasing the history size for openaf-console

Quick shell and shell commands from openaf-console

Just create an alias like this in Windows:

> alias cmd=sh("cmd " + (__aliasparam.trim().length>0 ? "/c " + __aliasparam : ""), void 0, void 0, true)

or like this in cygwin:

> alias cmd=sh("bash " + (__aliasparam.trim().length>0 ? "-c " + __aliasparam : ""), void 0, void 0, true)

or like this in unix:

> alias cmd=sh("stty icanon echo 2>/dev/null && /bin/bash "+(__aliasparam.trim().length>0?" -c "+__aliasparam:"") + " && stty -icanon min 1 -echo 2>/dev/null",void 0,void 0,true)

Then to use it if just execute "cmd" you will get the full shell and exit will get you back to openaf-console. If you execute "cmd someCommand" the command will be executed.

Note: nightly builds include an equivalent openaf-console alias "sh".
