g

Goat command

Command structure resembles substitute command- :g/re/command will run command over all lines (not words) matching the regular expresson pattern re

• :g/re will print at the bottom of the screen all lines matching pattern re (default command p is used here)
• :g/pattern/normal @a plays the a macro on all lines matching pattern
• :g/pattern/normal A. appends a dot . on all lines matching pattern
• :g/console/g/two/d is an example of recursive command
  • console first matches lines containing console
  • and then second g filters out matches containing two from the earlier matched
  • then applies d command
• :g/pattern1/,/pattern2/command makes Vim will apply the command within pattern1 and pattern2
  • /^$/ matches empty lines (with no character)
  • :g/^$/,/./j basically matches empty lines (^$) and non empty lines (.) and joins them (j)
• Delimiter can be changed like the substitute command, use any character except for alphabets, numbers, ”, |, and .
  • :g@console@d deletes all lines containing console
• g and s command can be conviniently combined
  • :g@one@s+const+let+g matches lines containing one
  • and then uses the substitute to replace const with let (last g for applying substitute on all matches within the matched lines)
  • could also use g/one/s/const/let/g
• :g/TODO/t $ copies all lines matching pattern TODO at the end of file (:h :copy)
  • Invert also works :g!/TODO/t $ copy everything except TODOs at end of file
  • :g/TODO/m $ moves all TODOs instead of copying them
• :g/console/d _ deletes all lines matching pattern console and puts them in black hole register _
