How to execute multiple global commands in Vim not sequentially?

Question

Using following test input:

***********
aaa
bbb
ccc
***********
ddd
eee
fff
-----------
ggg
hhh
iii
-----------
jjj
kkk
lll
-----------
***********
aaa
bbb
ccc
***********
ddd
eee
fff
-----------

Following method is close to what i'm looking for:

(i'm in need of using different ranges for each matches)

:execute 'g/ccc/-0,+0#' | execute 'g/eee/-1,+2#'

  4 ccc     <<----------- first returns lines with ccc, then with eee
 21 ccc
  6 ddd
  7 eee
  8 fff
  9 -----------
 23 ddd
 24 eee
 25 fff
 26 -----------  

Above output seems to show that the multiple global commands are executed sequentially. So, i get the "ccc" matches first from first global. Then comes the next set of matches from second global.

Is there way to run these global matches/commands on each lines in a single pass?

How would i go about getting following output instead?

  4 ccc
  6 ddd
  7 eee
  8 fff
  9 -----------
 21 ccc     <<-----------
 23 ddd
 24 eee
 25 fff
 26 -----------  

Answer 1

Yes, that's the way the :g command works. If you execute two :g commands after each other, do not be surprised, if they will be executed after each other :)

So you need to do it in one single pass. For that match the lines with a single :g command and then execute the # depending on the line content with different ranges. Something like this should work:

:g/eee\|ccc/if getline('.')=~'eee'|.-,.+2#|else|#|endif 

Note: No :exe needed in this case.
