Hello everyone,
I have been battling with trailing ^M on Windows, and I was wondering if
any of you could help me figure it out.
Let's create a file with `\r\n`s (that's how the clipboard appears to be
populated when I copy things from Chrome):
> echo -en "OS cliboards are hart...\r\naren't they?\r\n" > clipboard.txt
> cat clipboard.txt
OS cliboards are hart...
aren't they?
> cat clipboard.txt -A
OS cliboards are hart...^M$
aren't they?^M$
Let's open up vim now (`vim -u NONE`) and do some experiments:
1) read 'clipboard.txt', under the cursor
:read clipboard.txt
The content is loaded, not trailing ^M, at the bottom I see:
"clpboard.txt" [dos format] 2 lines, 40 characters
2) load 'clipboard.txt' using `read!`
:read! cat clipboard.txt
The content is loaded, no trailing ^M
3) load the content into a variable, then paste it under the cursor
:let @@ = system('cat clipboard.txt') | exe 'normal p'
The content is loaded, trailing ^M are added
Let's now push the file into the OS clipboard:
> cat clipboard.txt | clip.exe
Open up vim again, and:
4) paste from the `*` register (works with `Shift+Ins` too):
:exe 'normal "*p'
OS clipboard is read, no trailing ^M
5) load the content of the clipboard using `read!`
:read! powershell.exe Get-Clipboard
The content is loaded, no trailing ^M
6) Read the content of the clipboard into a variable, then paste it under the cursor
:let @@ = system('powershell.exe Get-Clipboard') | exe 'normal p'
OS clipboard is read, trailing ^M are added
These last 2 experiments, really, left me speechless: in both cases we
are reading the output of a command, but somehow `:read` seems to strip
^M, while `system()` not. Can someone help me figure this out?
Thanks
