goportal

Send command to another terminal that running goportal in Go.

Motivation

Since continuously, I hope i can run a shell in Vim. But i don't find a good solution. One day, I find tslime.vim (https://github.com/jgdavey/tslime.vim). But i don't use tmux. So I think I can write a program send command from terminal to terminal.

Installation

Install or update

go get -u github.com/cfrco/goportal

Usage

Start a Receiver

goportal -r <name>

End a Receiver

Always use this command to end receiver. For sure it remove FIFO files.

goportal -i <name> end

Use Sender to send command

Normal command

goportal <name> <command...>

Redo previous command

goportal <name>

Send goportal interanl command

goportal -i <name> <internal_cmd> <args...>

Send non-processed command

Normally, goportal automatically add " for each argument.
For example,ls -al will be "ls" "-al" and echo '"hello world!"' will be "echo" "\"hello world\"".
It's OK for those case. But it may cause problem in some case.(ls -al | grep go => "ls" "-al" "|" "grep" "go").
And pipeline can't work. In this case, use -o.

goportal -o test ls -al "|" grep go

IMPORTANT : | should be "|",or it will be pipeline's redirection for goportal -o test ls -al.

Internal Command

goportal -i <name> cd <path>     # change directory.
goportal -i <name> ret           # display `$?`(the last command's return value).
goportal -i <name> history       # display history commands.
goportal -i <name> end           # end the receiver.
goportal -i <name> set "<var-name> = <command>"
                                 # save command
goportal -i <name> @ <var-name>  # call command
goportal -i <name> ls            # list all saved commands
