Treat stdin as text by default (so the "-" file is not needed):
echo foo | nvim
It works with file args (implemented in next commit), too:
echo foo | nvim file1.txt file2.txt
Why? Because:
- Execution of input is (1) almost always unintentional/confusing,
and (2) potentially destructive.
- Avoids the need for time-delayed warning. #7659
- The _common_ case is to open text in a buffer, not send commands.
Note:
- Not for Ex-mode (-es) because it is used by scripts. But maybe `-Es`?
- Not for --headless, because stdio may be a protocol stream and may be
used for any purpose by stdioopen().
To treat stdin as Normal-mode commands, use `-s -` instead:
echo ifoo | nvim -s -
Other alternatives:
- Replay a register. E.g. the following mostly works, except @q aborts
on any "beep" (e.g. if the cursor can't move).
nvim -c '%d q|norm @q' -
- Future: Let `:%source` work with unsaved buffer contents?
