vim：根据一个：global命令运行多个命令

Question

Apologies if this has been posted already, for I cannot find an answer, even on the vim wiki.

Is there a way I can run multiple commands in vim command-line mode off of a single :g search?

For example,

:%g/foo/ s/bar/\=@a/g | exe "norm /cat\<enter>\"ayiw"

Which (for what I intend it to do) should, on every line matching foo , replace bar with the contents of register a , and then find the next iteration of cat (even if it is many lines ahead), and put the surrounding word into register a .

Instead, this specific syntax completes the subsitution command using the current contents of the initial a register, and then executes the normal mode command on a single line (after the substitution has been completed).

This example is not my specific use-case but shows one instance where this functionality is useful. I realize I could put it all into a single exe , ie, %g/foo/exe "norm :s/bar/\\\\=@a/g\\<enter>/cat\\<enter>\\"ayiw" , but I would like to do it the first way, as I feel it is more flexible.

I would prefer to do this using vanilla vim, but if a plugin exists for this, that is an okay alternative. Does anybody know if there is syntax to do such a thing?

Okay a "little bit" dirty, but does this work for you?

:let list = split(execute('g/cat/p'), '\n') | g/foo/ s/bar/\=matchstr(remove(list, 0), '\s\d\+\s\zs.*')/g

It first reads all occurences of cat save them in a list. Then replace the first bar with the first cat... and so on.

The dirty part ist the matchstr command. the g//p also returns a number for the result so the list looks like this:

 1 cat
 2 cat
 3 cat
 ...

that's why we have to remove a bit from the front. I would love to hear if someone knows a clean solution for that (I am also interested in a clean vimscript solution, does not have to be a oneliner).

You can do this (at least for multiple :s commands applied to a single :g). Example:

" SHORT STORY TITLES to single word of CapitalizedWords within <h3>s
.,$g/^\L\+$/s/[^A-Z0-9 ]\+//ge|s/\u\+/\L&/ge|s/\<\l\+\>/\u&/ge|s/ \+//ge|s/.*/<h3>&<\/h3>/
