Hi,
My bundle which is something like
bundle edit_line lines_between_delimiters(com,tag,lines) {
vars:
any::
"start_limiter_reg"
string => "$(com)\[$(tag)-begin\]";
"end_limiter_reg"
string => "$(com)\[$(tag)-end\]";
delete_lines:
any::
".*"
comment => "Delete all lines between the delimiters. This way we can
modify the lines.",
select_region => in_between("$(start_limiter_reg)","$(end_limiter_reg)");
insert_lines:
any::
"$(lines)"
comment => "Text between the delimiters.",
select_region => in_between("$(start_limiter_reg)",
"$(end_limiter_reg)");
}
body select_region in_between(start,end) {
select_start => "$(start)";
select_end => "$(end)";
}
seems to work perfectly. Cfengine updates the text between delimiters nicely.
In the example I have assumed that the delimiters exist. I must admit that I
had some problems with this in previous cfengine versions, but now (version
3.1.5) a bundle like this works.
