Question

我记得,有一篇文章,或几篇文章围绕作者如何根据SSH地址从绿色(发展)到红(生产)改变终点站的颜色。

But I am not sure how to replicate that with Heroku console.

理想的情况是,我要说的是蓝色,当时我是heroku console-remoteing ,然后是红色的,当时我是heroku console -remote production。

是否有任何建议?

Answer 1

在作为生产环境一部分装上的任何档案中(例如,config/environments/production.rb),你可以提出:

if defined? IRB
  # whew!
  conf = IRB.conf[:PROMPT][IRB.conf[:PROMPT_MODE]]
  red = "33[0;31m"
  reset = "33[0m"
  conf[:PROMPT_S] = "#{red}>> #{reset}" # regular prompt
end

The crazy escape characters are ANSI color codes. The "33" is an escape character, and the rest is a code for a particular color or effect. You can find a list of other colors and effects here. That IRB.conf hash is a global conf for IRB. You may want to set a few other keys on it - they re documented here.

如果你不使用铁路(因此不一定有环境档案),那么你总是可以通过使用ENV[RACK_ENV]来检查目前的环境。

Answer 2

我通过使用Marco Polo gem 。

然后,你可以迅速改变你的 con子,确定 her湖的conf状。你可以利用逃脱法来改变肤色。在我的案件中,我确定,这种生产在五大背景(难以误导)下,利用这种控制顺序进行白化,以达到《防污公约》的价值。

[ESC][105;97;1mPRODUCTION[ESC][0m

不幸的是,Stack Overflow赢得了帽子,让我揭开越狱本身。你们不得不使用“灯塔”++,并用X1B取代“ESC”。之后,你可以复制并贴出在Heroku console的MARCO_POLO_APP_NAME的价值。我无法将其置于指挥线。

Answer 3

untested, but something along the lines of this in your .bashrc or whatever may be what you want (it s not completely safe but you should get the idea)

function heroku {
  REMOTE_TERMINAL_THEME_NAME="Solarized Light"
  CURTAB=$(osascript -e "tell application "Terminal" to get the selected tab of the front window")
  CURTHEME=$(osascript -e "tell application "Terminal" to get the name of current settings of the selected tab of the front window")
  HEROKU=$(which heroku)
  osascript -e "tell application "Terminal" to set current settings of $CURTAB to settings set "$REMOTE_TERMINAL_THEME_NAME""

  $HEROKU "$@"
  osascript -e "tell application "Terminal" to set current settings of $CURTAB to settings set  "$CURTHEME""
}

我把它用于sh,但从概念上说是一样的:凌驾于你的指挥,其职能是使用撒布特来改变终端环境,然后将其撤回。基于论点的转换应当比较容易增加。

Answer 4

在我看来,当你把 alia子打成 alia子或bat子时,你可以将其自动化。有一个条款,即简单的对应指挥可以改变你的肤色,直到你再回来。

因此,如果您的一位六位用户,你可以与你一道这样做。

#pretend this is a bunch of prompt setup
#USER ALIASES
alias heroku-staging="export     PS1="e[0;34m[Heroku Staging]$]" && heroku console --remote staging"

然后,仅打上 her湖。
