oh my zsh showing weird character '?' on terminal

阅读更多关于 oh my zsh showing weird character '?' on terminal

I have installed iTerm2 and Oh-my-zsh. However there is a weird question mark that is coming ever since I have changed ZSH-THEME to "agnoster". Attaching the screenshot for the same. I thought powerline would help but that doesn't seem to happen. Can can anyone help me with this? Installing a powerline patched font will solve this. This official documentation provides description about installing poweline fonts. There are two ways to enable powerline patched font in iTerm2. Set a powerline patched font as default. Set a powerline patched font for only Non-ASCII characters and use another font

Make zsh complete arguments from a file

阅读更多关于 Make zsh complete arguments from a file

问题 zsh is great but its completion system is very diverse. And the documentation lacks good examples. Is there a template for completing for a specific application. The completion would get its match data from a file, separated by newlines? I tried modifying an older example of mine that takes match data "live": ~ % cat .zsh/completers/_jazzup #compdef jazz_up _arguments "2: :(`mpc lsplaylists|sed -e 's# #\\\\ #g'`)" I could supply cat my_file there instead of mpc invocation and so on but would

Now the Ruby is set as default but RVM doesn't load it as "current", which means it does not load the gemsets that are affiliated to it. I have no .bashrc nor .bash_profile . There is no RVM reference in my .zprofile and here is my .zshrc : # Path to your oh-my-zsh configuration. ZSH=$HOME/.oh-my-zsh # Set name of the theme to load.

zsh: use completions for command X when I type command Y

阅读更多关于 zsh: use completions for command X when I type command Y

问题 In zsh, I have a function called g which acts like this: with no arguments, call git status with one or more arguments, delegate to git with all given arguments - i.e. call git $@ I would like the tab completions for g to be exactly the same as for git . I can achieve this with alias g=git , but that doesn't allow me to call status by default (the first point above). How can I delegate to the completion for git ? In bash, I simply did complete -F _git g which re-uses git's completion function

I would like to make it look like this: zoltan@Macbook-Pro ~ % Any suggestion would be greatly appreciated. Thank you! 回答1: It's a bit of a mess, but you can pretend the %m is a parameter and use parameter expansion to strip the zoltan from the host name: PROMPT="...${${(%):-%m}#1}
