Moving to GitHub, slowly

The software on this pages will slowly be moved to GitHub https://github.com/hilbix/. The CVS repository will be migrated to GIT as well, so the history will be preserved, a bit. See FAQ.

Scylla and Charybdis, printansi - Tools

The tools are developed under Linux with ESR's paradigm release early, release often in mind.
So you can consider this beta software, or alpha, or pre-alpha, or even worse ;)

Have a look in the download directory for all downloads.
As always here, all you get is the source. No binaries here.

printansi 0.1.0-20100112-032113

Like /bin/echo but ANSI-escapes the output

⇒ ⇒ ⇒ The development shifted to another location. All future versions will be published at https://github.com/hilbix/printansi ⇐ ⇐ ⇐

Printansi echos the arguments to stdout (or a file) ANSI-escaped. The arguments are separated by spaces and ends the line with LF.

This way you can preserve the arguments between shell sessions, by reading them in again. Example:

a='arg with
newline'
b="arg with shell '"'" shell'
printansi "$a" "$b" > /tmp/preserve.file.$$
read -r c d < /tmp/preserve.file.$$
eval c="\$'$c'"
eval d="\$'$d'"
if [ ".$a" = ".$c" ] || [ ".$b" != ".$d" ]; then echo "fail"; fi

Please note that the "read" and "eval" completely runs in the shell without any forks, so it's quick.

If you invoke it with -f it automatically creates and locks the file.

Options -l when combined with option -f are a quick version of following line:

while read -r a; do printansi -f "file" "$a"; done

Option -z is the same with NUL as line terminator.

I want to stress, that you must use read -r. If you forget the option -r you will see strange effects.

History:

version 0.1.0-20100112-032113

download (244127 bytes) sig

Options -d and -r added

Also possible race condition removed.

Now printansi can be used as a save logfile, like in

for a do echo "start $a" process "$a" echo "finished $a: $?" done | # Log lines "[YYYYMMDD-HHMMSS][PID] stdin" printansi -drp "[$$]" -lf logfile.out -

version 0.0.0-20090827-202636

download (244423 bytes) sig

First version, nearly untested.

As there is a new unit (io.h for put.h) in tinoLib, there might be grave bugs. We will see.
