coshr

Command Output Share

coshr is a bash script which allows you to easily share output of your commands with someone else. It previews the output of the command that was run, formats it to your liking and either copies it to your clipboard or uploads it directly to 0x0.

currently only works on wayland with wl-clipboard

Usage

The usage is best explained with some examples. If you want to follow along using the -v option helps you figure out what coshr is doing.

Basics

$ coshr 'echo Hello World!'
Hello World!
$ wl-paste
`echo Hello World!`
````
Hello World!
````

If you don't want to include the command you ran in your output add the -o flag:

$ coshr -o 'echo Hello World!'
Hello World!
$ wl-paste
````
Hello World!
````

You can also use stdin, note that this assumes -o because in this case coshr can't read which command you entered.

$ echo "Hello World!" | coshr
Hello World!
$ wl-paste
````
Hello World!
````

As you can see reading from stdin produces the same results as using the -o option.

Formats

As you probably noticed the default output format is markdown. You can specify which format you want to use with the -f <format> flag. Currently, there are 3 available formats:

• md for markdown
• plain for no formatting at all
• html for generating html based on a template

$ coshr -f plain 'echo "Hello World!"'
Hello World!
$ wl-paste
echo "Hello World!"

Hello World!

Uploading

If you want to upload the command output instead of copying it to your clipboard you can use the -u option. This will upload what would normally be copied to your clipboard to 0x0 and copy the URL into your clipboard. This works great in combination with -f html.

$ coshr -f html -u 'fortune | cowsay'

HTML

coshr can generate HTML for your output using -f html. This HTML is based on a template (by default '/usr/share/doc/coshr/template.html'). The template file includes 4 HTML comments which let coshr know what it should do with the template.

• <!--STARTCMD--!> designates the start of the CMD section.
• <!--CMD--!> is going to be replaced by the name of the command.
• <!--ENDCMD--!> designates the end of the CMD section.
• <!--OUTPUT--!> is going to be replaced by the output of the command.

As we covered earlier coshr doesn't always know and / or use the command you ran in its output. If this is the case, everything in the CMD section is removed from the output html.

A good starting point can be found in the example template

Special characters

coshr automatically removes special characters from the output of your command in order to properly display it. Coshr will preview the output after it has been filtered. A great example of this is neofetch, where you can see that the colors are stripped and the formatting is a little different. Try it for yourself.

$ neofetch | coshr

Configuration

you can place a configuration file in $HOME/.config/coshr/config. This file is getting sourced at the beginning of the script, so it's a simple KEY=VALUE file. The command line arguments always overwrite the config. Following keys are allowed:

• FORMAT specifies the default format.
• INSTANCE URL for the 0x0 instance you want to use.
• TEMPLATE Path to the HTML template you want to use.

Installing

if you are on arch linux you can use the coshr-git AUR package.

For everyone else you can:

1. Clone the repo:

   git clone https://github.com/jeidnx/coshr
   

2. Enter the repo:

   cd coshr
   

3. Install via makefile

   sudo make install
   

if you want to quickly copy your last action, you can paste this snippet into your shells rc file. Usage is the same as coshr, but instead of providing a command, it uses your last ran command automatically.

coshrl() {
  coshr "$@" "$(fc -ln -1)"
}

TODO:

• Fix error where markdown is malformed when 4 backticks are in the output of the command
• Enable the use of clipboards other than wl-clipboard
• Enable formatting of copied text for already ran commands which can't be re-run quickly
