xta / halloweenbash Goto Github PK

You use a shell fucntion in PS1
But when you "cd" to a git repo dir, you need source ~/.bashrc to go the git branch display in the command prompt. and then you cd to other dir(not a git repo), and the branch is staill in the bash prompt...

Is any error in my environ (arch-linux , bash) ?
I then use PROMPT_COMMAND solve this:

export PROMPT_COMMAND='RET=$?;\
  BRANCH="";\
  ERRMSG="";\
  if [[ $RET != 0 ]]; then\
    ERRMSG=" $RET";\
  fi;\
  if git branch 2>/dev/null 1>/dev/null; then\
    BRANCH=$(git branch 2>/dev/null | grep \* |  cut -d " " -f 2);\
  fi;
  user="\[\e[0;31m\]\u"
  host="\[\e[0;32m\]\h"
  fdir="\[\e[1;34m\]\w"
  prompt="\[\e[0;31m\]\$"
  data="\[\e[0;36m\]date:$BOLD\D{%c}"
  git_branch="\[\e[0;33m\]$BRANCH\[\e[m\]"
  ter_color="\[\e[0;32m\]"
  PS1="$user@$host $fdir $prompt $data $git_branch $ter_color\n>"
  #PS1="$GREEN\u@\h $BLUE\W $CYAN$BRANCH$RED$ERRMSG \$ $LIGHT_GRAY";'

thx

ptw: awesome project !

When you drag a space up, you can never drag another space there, since it disappears :)

Like I do for my own. Just allow the color selections to get dragged into the PS1 box. This makes it easy to color branch and path names (for example) differently, so they stand out.

Look:

I'm using "acpi" for ubuntu: Check here

temperature () { acpi -t | grep -Eo '[0-9]+.{2,4}'| awk '{print $1}' | head -2 | tail -1; }

I'd love to be able to drag/drop my current git branch into the prompt!

If has something to stage -> red

otherwhise -> green

Look the source here

If you start $PS1 with ': ' and end with '; ' then you cut-n-paste entire command lines more easily (no need to grab from the end of the prompt).

Bonus: single-quote the rest of the PS1 to avoid glob injection.

Bonus: set PS2= to further help the cut-n-paste of long command-lines.

Bonus: add number of files dirty (modified/added/deleted in git workspace or index but not committed).

Bonus: add support for other VCSes.

I have support for Fossil, Mercurial, and git, in my shell startup. I've a set of functions for this. I like to format my prompt like this:

: vcs:project[branch]:TOP/.../basename-of-PWD[number-of-dirty-files:number-of-history-commands]%;

plus colors. See my .kshaliases. I then set PS1='$(vcs_ps1)'.

Yes, ksh, I know. Not too hard to port to bash. See https://github.com/jakobi/script-archive/blob/master/cli.shell.functions/dir.shell/cd.nico_cd_for_bash_and_ksh.func for some help with writing ksh/bash compat code (also, those functions are awesome).

When using "$ " as the end of my PS1 string on OS X, the $ doesn't change into a # after switching to root.

I have to either change it to "$ " or use single quotes around the exported PS1 string.

for the common user@host

Nice work on this. Few little suggestions:

1. Can you add the characters < > @, or to be able to just type some in?
2. You could make the colours just so you drag them in like the other markers (maybe with interface like (red fg ->) or something to show it's red foreground from here onwards.
3. Maybe you could categorise the items into dynamic/static/colours. eg.
   • Dynamic: hostname, dates, user, etc
   • Static: Spaces, other characters
   • Colours: start of a new colour, as above
4. Would also be good if the items from the palette never moved, so we don't have to find them each time, and can get used to the position of the items

Really nice idea though!

There's not an escape code for it like the others, but \$? works fine in a "-quoted string.

Look:

I'm using this code below for ubuntu: Check here

aram () { free -m | awk '{print $4}' | head -2 | tail -1; }

You remove every item from Your Configuration section, it seems I can no longer add a thing to it. A page reload is needed to "fix" the situation.

Btw, great work on this too. Very useful. 👍

In my PS1, I find it useful to see the exit status of the last entered command. In order to do this, I need to define a function that dynamically changes PS1 using PROMPT_COMMAND

function exitstatus {
  if [ $? -eq 0 ]
  then
    export PS1="✓ $PROMPT"
  else
    export PS1="× $PROMPT"
  fi
}

PROMPT_COMMAND='exitstatus'

Does this seem like something worth adding to Halloween, or is the ceremony involved too much?

Can you pay for my now necessary ophthalmologist appointment?

Maybe you do have this feature. But I cannot figure it out on my MacBook running Chrome.
