Vim 在整个项目中查找和替换多行

Question

I have code like this:

        item = QStandardItem(self.list.icon, name)
        self.list.model.appendRow(item)
        self.list.model.sort(0)

And I want to replace it with this:

        add_database(self.list, name)

And I want to do it in my whole project (ie its directory). I use fzf and ferret vim plugins, can they help me somehow?

Answer 1

1. Open required files in vim with args command:

   args project_dir/**/*.py

2. Execute substitution on all opened files:

argdo %s;\(\s*\)item = QStandardItem(self.list.icon, name)\n\1self.list.model.appendRow(item)\n\1self.list.model.sort(0);\1add_database(self.list, name);g

It preserves indentation which is important in Python, as Kent noticed.

\n is new line symbol here.

\1 is group recall.

See help topics for more info:

:h :args
:h :argdo

Answer 2

If you use ripgrep, you can do this from the commandline: rg -l 'my_search' | xargs sed -i '' -e 's/my_search/my_new_value/' rg -l 'my_search' | xargs sed -i '' -e 's/my_search/my_new_value/'

Or if you want an in-vim solution, this will also work: :cfdo %s/my_search/replacement/gc and :cdo update to update.
