valiev / almostontop Goto Github PK

When you press enter after typing a command, screen always blinks for a second as the plugin calls clear internally. I find that slightly annoying so I was wondering if it could be replaced with something which doesn't cause the flickering? Maybe this post could serve as an inspiration. Might even do a PR if I find time. Thanks for considering this, Petr

almostontop_preexec:7: bad substitution

Hi,

This plugin can be very useful for cases with output longer than one screen. It will be nice to read stdout from the top, instead of scrolling the terminal up to the place where a command was written, and making sure that you will not miss that spot like always ;)

For example, $ echo $EDITOR without almostontop just gets executed as $ echo $EDITOR

But with almostontop, it gets replaced with $ echo ~/bin/micro

In 0.5.0, the screen would clear only after actually running a command. If I just pressed return one or more times, lines would be added as they would be in a zsh without almostontop. This seemed the correct and unsurprising behavior.

In 0.6.0, pressing return clears the screen, but leaves two prompt lines on the screen. (Just press return once and you'll see -- let me know if you need a screen shot.)

It seems that the plugin should do one or the other -- either clear the screen after an empty command, leaving only one line with the current prompt, or allow multiple empty commands to stack up before clearing the screen for a real command.

When you're typing a command zsh-syntax-highlighting does it's thing and the command is correctly highlighted but once you press enter and almostontop kicks in, the highlighting is lost -- it's just a minor annoyance and you can always just scroll up and look at the highlighted command above but I thought I'd just report it anyway in case it's easy to fix.

See this for a demonstration.

I prefer to have this plugin keep the scrollback buffer when clearing the screen.
To do so I added the -x flag to the clear command on line 16 of almostontop.plugin.zsh.
Now after every command the screen is cleared but I am still able to access the outputs of previous commands by scrolling up.
