- - Bash Harder With Vim - -

Bash is tricky, don’t let your editor get in your way. Here’s a couple of neat -additions you could make to your vimrc for a better shell programming -experience.

- -

Man pages inside vim

- -

Source this script to get started:

- -

runtime ftplugin/man.vim
-

- -

Now, you can open manpages inside vim with :Man! It adds nicer syntax highlighting -and the ability to jump around with Ctrl-] and Ctrl-T.

- -

By default, the manpage is opened in a horizontal split, I prefer using a new tab:

- -

let g:ft_man_open_mode = 'tab'
-

- -

Scratchpad to test your commands

- -

I often test my sed substitutions, here is -a sample from the script used to generate this site:

- -

# a substitution to convert snake_case to Title Case With Spaces
-echo "$1" | sed -E -e "s/\..+$//g"  -e "s/_(.)/ \u\1/g" -e "s/^(.)/\u\1/g"
-

- -

Instead of dropping into a new shell, just test it out directly from vim!

- -

Yank the line into a register:
- -
```
yy
-
```
Paste it into the command-line window:
- -
```
q:p
-
```

Make edits as required:

- -

syntax off            # previously run commands
-edit index.html       # in a buffer!
-w | so %
-!echo "new_post.md" | sed -E -e "s/\..+$//g"  --snip--
-^--- note the use of '!'
-

Hit enter with the cursor on the line containing your command!

- -

$ vim
-New Post         # output
-Press ENTER or type command to continue
-
