Since you say “embedded system” and “small and fast” and “integrate nicely” I would say you are correct that Lua is the number one if not the only choice. But I no longer agree that the programming language has “quirky corners”. Firstly, the book Programming in Lua is simply splendid, one of the best books … Read more
You use the available task with type set to “dir”. For example: <available file=”${dir}” type=”dir”/> The standard way to do conditional processing is with the condition task. In the example below, running doFoo will echo a message if the directory exists, whereas running doBar will echo a message unless the directory exists. The dir.check target … Read more
You can do: ssh user@host ‘bash -s’ < /path/script.sh
Basically, in this example I wanted to get some variable values in particular places of the code; and have them output until the program crashes. So here is first a little program which is guaranteed to crash in a few steps, test.c: #include <stdio.h> #include <stdlib.h> int icount = 1; // default value main(int argc, … Read more
To append after the pattern: (-i is for in place replace). line1 and line2 are the lines you want to append(or prepend) sed -i ‘/pattern/a \ line1 \ line2’ inputfile Output: #cat inputfile pattern line1 line2 To prepend the lines before: sed -i ‘/pattern/i \ line1 \ line2’ inputfile Output: #cat inputfile line1 line2 pattern
For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected). Wikipedia seems to agree with me on this : Script : “Scripts” are distinct from the core code of the application, which is usually written … Read more
If you’re shell is running on .NET 4.0 (PowerShell 3.0): PS> [Environment]::Is64BitProcess True
The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes: “string with an embedded “” character”
A more clear usage might be to use switch parameters instead. Then, just the existence of the Unify parameter would mean it was set. Like so: param ( [int] $Turn, [switch] $Unify )
My o key fell off on my laptop; so I wrote a program that replaces two 0 keystrokes within 200 MS of each other as an o, two 0 keystrokes within 700 MS of each other as a 0 and ignore the rest; so I could use my laptop before I get around to replacing … Read more
