Day 48: Another Go program, and a little vim configuration
On Wednesday I was feeling tired so I didn’t do too much. I just translated my bash script to set up device mapper from the day before to a Go program.
Today I think I’ll integrate that Go code into my main program!
the go program: set up device mapper
I wrote a little go code which does
basically the same thing as the bash script from yesterday (sets up some
/dev/mappers).
some fun with vim
I never set up my vim, but when writing Go this week I decided to give the
vim-go plugin another shot. So far I’m using 3 features from it:
- it runs
go fmtto I save - I can run
<leader>gbto build my Go program - If I do
Ctrl+Enter, it goes to the definition of the function
The format and builder things are fine (it doesn’t seem that much better to me than just switching to a terminal to do the same thing), but the go to definition thing is GREAT. I was trying to read some code from Ignite and it made it a lot faster and easier.
Usually I do “go to definition” with a lot of grep so this was a lot faster.
