vim motions in bash shell

If you want vim motions in your bash CLI, put this in your $HOME/.inputrc:

1set editing-mode vi
2set show-mode-in-prompt on
3set vi-ins-mode-string \1\e[6 q\2
4set vi-cmd-mode-string \1\e[2 q\2

Now you can enter vim Normal mode with ESC or CTRL+[.

When in Normal mode in bash, if you press v the command in the current line gets opened in a vim buffer! This is very useful for editing long commands in the comfort of the editor.

create table of contents in markdown files (the easy way)

• Download markdown-toc
• Insert !-- toc --> where you want the table of content in your file.
• Run markdown-toc -i filename.md to create the table of content.

In vim, run :!markdown-toc -i "%" using a keybinding like leader-t and your good to go.

I sometimes like to insert emojis at the start of headers (if you don’t approove it, you are too old 😙) and then make a toc with above mentioned method.

Problem is that when the markdown is rendered on Github, the emoji is part of the link gets underlined with the usual blue link bar.

I don’t like it.

So I made a sed command that formats the toc as I like and saved it in a script called t4g. I just select the lines in visual mode and run :!t4g.

I also needed one that formats the toc for Obsidian: t4o.

Here the sed commands:

1# t4g (*t*oc*4g*ithub)
2sed 's:\[\([^ ]*\) \(.*\)\](#[^-]*-\(.*\)):\1 \[\2\](#-\3):'

1# t4o (*t*oc*4o*bsidian)
2sed 's:\[\([^ ]*\) \(.*\)\](#[^-]*-\(.*\)):\1 \[\2\](#-\3):'

Given this toc:

- [😃 Smiling](#%F0%9F%98%83-smiling)
- [😻 Lovely cat](#%F0%9F%98%BB-lovely-cat)
  * [😅 Grinning subheader](#%F0%9F%98%85-grinning-subheader)

The scripts transform it like this:

# t4g
- 😃 [Smiling](#-smiling)
- 😻 [Lovely cat](#-lovely-cat)
  * 😅 [Grinning subheader](#-grinning-subheader)

# t4o
- [[#😃 Smiling]]
- [[#😻 Lovely cat]]
  * [[#😅 Grinning subheader]]
