Somebody told me they always use US keyboard for coding, and that it really makes a difference. I typically don't care too much about such, but when I started getting a slight pain in my wrists the other day, after many days of intense bash-/vim-/screening, I decided to make a try ... and my hands and wrists are forever grateful!
Finally it starts to make sense why somebody would choose a weird character such as " for switching between windows in screen! (something you do very repeateadly sometimes), but having it just one step to the right of the natural position of your right pinkie, makes more sense than the awful crippled left-hand grip to get [shift]- on the swedish keyboard.
Coders in general will save some sanity by avoid the crippled right hand-grip with AltGr+[numkey] to get to
The rest is maybe a little more specific to heavy bash/vim/screen usage. I'll outline a few that I noticed below:
:, for the ubiquitous
:win vim (for saving( is very comfy placed under your right pinkie (with shift).
$sign is much comfier (for selecting to end of line in vim), avoiding another crippled AltGr-grip.
/, for searching in vim, is really nicely placed one step down and right from the right pinkie.
"is nicely placed just one step to the right of the pinkie-placement.
~, even though requiring a slightly crippled left-hand grip even in US, at least prints out directly, as opposed to the required space to force it to print, in SE.
I'm sure there are many more, but these should be enough to make it worth to try it out a little if you're spending a lot of time in bash/vim/screen. In short: Only now I can see how anyone can really love working with these vim commands!
Only thing remaining is to find a nice place to map the åäö:s.
So far, I have added these two aliases to my
~/.bash_aliases, though, for quick switching between Swedish and US:
alias kbse='setxkbmap se' alias kbus='setxkbmap us'
I often need to develop python scripts on some remote server where I can't run graphical python IDEs like spyder.
I'm too lazy to set up an advanced vim config with full blown IDE-like features (except for some basic python support).
I have found that a much simpler solution is a GNU screen session with two vertically split screens, one for the main coding in vim, and a smalelr one below, for running ipython, to run and debug the script as it is written.
I found it useful enough to figure out how to start such a setup with one command. This is how to do it:
create a file ~/.screenrc.pydev and place the following in it:
split screen focus screen resize 20 exec ipython focus exec vim
then add this to the bottom of your ~/.bashrc or ~/.bash_aliases:
alias pydev='screen -mS PyDev -c ~/.screenrc.pydev'
... and source the file:
Now, you can start your command line python environment by:
cd some-folder-with-python-files pydev
Oh, and to jump between the screen windows, do:
[Ctrl] + [A], [Tab]
GNU Screen is a nice little program, allowing you to have "terminals" that you can detach in the background, so that you can have long batch jobs started, outputting stuff to the stdout, for example, but still don't be afraid to close down your terminal by accident etc.
Unfortunately screen has, IMO, quite an awkward syntax, but I managed to learn 3 flag combinations, and two keyboard combinations (from inside screen) that seems to be what I need for basic usage of screen:
Start a new named screen session:
screen -dmS ASessionName
screen -r ASessionName
Detach the current session in background:
Ctrl + a, Ctrl + d
Ctrl + d
