Subject: Edit selected files

I have a simple requirement: edit selected hidden (i.e., "dot") files in home
directories.
The limitation that "depth search is not allowed with edit_line promises" seems
to make solving this problem unnecessarily difficult. I would really like to
see the arbitrary design constraint removed.
I have tried multiple solutions including a pattern in the promiser (works but
produces useless error messages) and a file_select (which seems to not work at
all). This is with community 3.0.5p1.
For example:
body common control
{
bundlesequence => {
"check_user_files"
};
inputs => {
"cfengine_stdlib.cf",
"library.cf"
};
}
bundle agent check_user_files
{
vars:
"HomeDirn" int => readstringarray(
"HomeDir",
"/etc/passwd",
".*:[*x]:([1-9]|\d{2}|1\d{1,2}|-2|204|205|430|65534|4294967294|1000):.*",
":",
"300",
"12000"
);
"HomeUsr" slist => getindices("HomeDir");
files:
any::
"$(HomeDir[$(HomeUsr)][5])/\..*"
edit_line => user_update,
edit_defaults => no_edit_backup;
}
bundle edit_line user_update
{
replace_patterns:
"oldvalue"
replace_with => value("newvalue");
}
body edit_defaults no_edit_backup
{
edit_backup => "false";
}
This above example works but generates numerous errors/warnings I don't want to
see:
Directory /home/admin/usera in search path /home/admin/usera/\..* is controlled
by another user (uid 10292) - trus
ting its content is potentially risky (possible race)
Promise (version not specified) belongs to bundle 'check_user_files' in file
'./check_user_files.cf' near line 30
-> Need to edit file /home/admin/usera/.profile but only a warning promised
I: Report relates to a promise with handle ""
I: Made in version 'not specified' of './check_user_files.cf' near line 30
/home/admin/usera/.dt is not a plain file
File /home/admin/usera/.dt was marked for editing but could not be opened
/home/admin/usera/.gnome is not a plain file
File /home/admin/usera/.gnome was marked for editing but could not be opened
/home/admin/usera/.gnome_private is not a plain file
File /home/admin/usera/.gnome_private was marked for editing but could not be
opened
/home/admin/usera/.ssh is not a plain file
When I try using file_select
files:
any::
"$(HomeDir[$(HomeUsr)][5])"
edit_line => umask_update,
edit_defaults => no_edit_backup,
file_select => by_path("\..*","/.*");
}
bundle edit_line umask_update
{
replace_patterns:
"oldvalue"
replace_with => value("newvalue");
}
body file_select by_path(leaf,path)
{
file_types => { "plain" };
leaf_name => { "$(leaf)" };
path_name => { "$(path)" };
file_result => "file_types.path_name.leaf_name";
}
it seems to be completely ignored, producing only the following message:
File /home/admin/usera was marked for editing but could not be opened
Anyone have any ideas? There's gotta be a way to do this.
Thanks in advance!
