Program internationalization: problem with gettext!

[Argolance]

Hello,
I created a script using the Shinobar's "simple localization script" and this works fine! Now I plan to use gettext instead but have got a problem that I tried to solve without success. In this part of code:

Code: Select all

TMP=$(grep -A 1 default "$HOME/.config/rox.sourceforge.net/ROX-Filer/globicons" | sed 's#<rule match=\"/usr/local/bin/#exec#g' | sed 's#\">##g' | sed 's#\">##g' | sed 's#<icon>#icon#g'| sed 's#</icon>##g' | sed 's# ##g'); echo "$TMP" > $HOME/.2Palt/temp

awk '/^exec/{LINE=substr($0,0);TARGET_FILE_NAME=substr($0,5);getline;print LINE"\n"substr($0,0)>TARGET_DIR"/""0_"TARGET_FILE_NAME}' TARGET_DIR="$HOME/.tray_apps" $HOME/.2Palt/temp

for I in $HOME/.tray_apps/0_default*; do
VAR="$(grep 'default' $I | sed 's/exec//g')"
echo "popup${!VAR}" >> "$I"; mv -f "$I" /$HOME/.tray_apps/"0_${!VAR}"
done

... I have to call variables ${!VAR} using gettext. Tried many possibilities but these don't work! For example, please see the (quite imperfectly translated!) *.mo English file below and affected variables

Where is there text string?

15.3.3 Shell Format Strings

Shell format strings, as supported by GNU gettext and the ‘envsubst’ program, are strings with references to shell variables in the form $variable or ${variable}. References of the form ${variable-default}, ${variable:-default}, ${variable=default}, ${variable:=default}, ${variable+replacement}, ${variable:+replacement}, ${variable?ignored}, ${variable:?ignored}, that would be valid inside shell scripts, are not supported. The variable names must consist solely of alphanumeric or underscore ASCII characters, not start with a digit and be nonempty; otherwise such a variable reference is ignored.

Hello, thank you for your answer!
What a pity! This should be patched...
