Interactive find and replace in files.
$ go install github.com/itayd/pounce@latest
$ tree
.
├── README.md
└── some
└── dir
└── dogs.txt
# First collect all lines to be modified.
$ pounce -crs 'dog' > /tmp/lines
$ cat /tmp/lines
README.md:1:I like dogs
some/dir/dogs.txt:3:dogs are the best!
# The idea is that this can be done interactively using vim.
# This allows trial and error and faster feedback, but for
# the sake of demo, we'll use sed.
$ sed -i '' -e 's/dog/cat/g' /tmp/lines
# Apply modifications.
$ pounce -a < /tmp/lines
$ cat README.md
I like cats
Interactive one liner version (will launch $EDITOR to modify lines):
$ pounce -s 'dog'
One liner version, using sed:
$ pounce -crs 'dog' | sed -e 's/dog/cat/g' | pounce -a
Edit all lines in all files:
$ pounce -s ''
- deal with colons in file names.
- deal with no EOL on last line of files.
-
\nvs\r\n? - apply: only generate backup files if content actually changed?
- apply: read/write piece wise.
- cli flags docs can be better phrased.
- make sure tests are portable.
Both cats and dogs are awesome.
