tools

This repository contains a bunch of stuff that I find useful. Some of it may be reusable, but most of it is probably useful only to myself.

To install any of these tools:

$ go install github.com/mpenkov/tools/<toolname>@latest

where is one of the below.

ghreview

Provides a summary of my github activity across several github repositories during a particular year.

$ ./ghreview 2022 RaRe-Technologies/gensim RaRe-Technologies/smart_open | tee ~/Dropbox/wiki/2022/so.html

hijack

Hijack a github PR in order to be able to push commits to it. Helpful for maintaining my open-source repos, e.g. gensim and smart_open.

kot

Like cat, but with auto-completion for S3 and HTTP (TODO). To install, first run:

 COMP_INSTALL=1 kot

and answer "yes" to the prompt.

kp

kp works with the copy-paste buffer

read stuff into the buffer (copy):

$ cat file.txt | grep foo | kp
$ cat file.txt | grep foo | kp copy -  # more verbose version of the above
$ kp copy file.txt

edit the contents of the buffer (using $EDITOR):

$ kp edit

write the contents of the buffer to stdout (like a paste):

$ kp paste

shin

SSH into an EC2 instance by its ID:

$ shin i-12345689

Requires IDENTITY_FILE_PATH environment variable to be set to e.g. ~/.ssh/identity.pem

Offers a helpful -register flag that updates ~/.ssh/config to simplify reconnecting to the instance, using scp, etc. For example:

$ shin -register -alias worker -dnc i-12345689
# <shin>
Host worker
        Hostname 1.2.3.4
        User ubuntu
        IdentityFile /home/misha/.ssh/identity.pem
        StrictHostKeyChecking=accept-new
# </shin>

The "-dnc" flag prevents shin from making the initial SSH connection. The "-alias" flag specifies what to call the new host. It will default to the instance ID, or the instance's name, if it has a "Name" tag. The standard output shows what was added to your ~/.ssh/config file. You can now do this:

$ ssh worker ls
misha@cabron:~/git/tools/shin$ ssh worker ls -lh /home

workswitch

This application glues i3 with various command-line utilities to make my work more productive. Features include:

• Each i3 workspace keeps its own state:
  • Input language (Russian, English, Japanese)
  • Mouse position
  • Touchpad inhibition status
• Switch between different languages with a single command
  • For Russian, I switch the X keyboard layout (setxkmap)
  • For Japanese, I use ibus with mozc-jp
• Output the keyboard layout and touchpad inhibition status (for i3blocks)
