Markdown newline inside quote

Couldn’t understand why there are newlinen in my yearly review blog post from last year. So - in markdown, two spaces and then a line break create a line break.

So, like this:
One
two

Three
Four
Fine, no spaces Six, no spaces

Highlight to see spaces:

So, like this:  
One  
*two*  

> Three  
> Four  
> Fine, no spaces
> Six, no spaces

vim show trailing whitespaces

In connection to the above, yes. Updated ~/.vimrc with the following:

set listchars=tab:\:\ 
set listchars+=trail:◦

Looks like this:

vim CONVERSION ERROR - convert file to different encoding / save with other encoding.

For the above had to convert my ~/.vimrc to utf-8, not the default latin-1:
:w ++enc=utf-8

vim insert utf-8 characters

• Insert mode
• <C-v> u25e6 (for “◦”/U+25E6, for example)

i3 keybinding to make a screenshot and put it into jekyll assets directory

This makes a screenshot as usual, opens it, opens the jekyll dtb assets folder, and puts the screenhsot name in the primary clipboard. I look at the screenshot, if I like it - I drag it directly to the folder, then use the vim/jekyll binding to insert it in the markdown.

bindsym Mod3+Shift+s --release exec scrot -s -e 'mv $f ~/s/screenshots && nomacs ~/s/screenshots/$f & echo -n $f | xclip -selection c && thunar ~/o/dtb/assets/pics/screenshots/'

echo -n is echo without newline (otherwise it gets fed to xc with newline appended). Added to ~/.config/i3/config.

Feels incredibly ugly and unstable but works for me I guess. Ideally it’s long enough to be replaced with a bash script, but not sure it’s worth it. But if I end up doing more of these, I’ll create a one custom big parametrized bash script that I’ll call like ./big-script.sh screenshot.

vim jekyll binding to insert screenshot picture

map <leader>p i![](/assets/pics/screenshots/<esc>pa)<esc>0lli in ~/.vimrc

Inserts a picture with filename from primary selection, then goes back to the description. Used with new i3 screenshot keybinding from above. a in vim is “insert from next character”, so like A but with words.

I really do need to use a/e etc in vim more often.

camel / snake / kebab notation, note to self.

I seem to use more of-this-notation lately, instead of this_notation. Formalize this, not just for consistency, but to use this to my advantage - vim and company see these-words as separate, and this_word as one.

bash echo without newline at the end

echo -n doesn’t add a newline. Especially useful combined with xclip.

Taskwarrior / zsh

Updated zsh alias to include non-work tasks tagged +A or +O from current sprint:

s () {task s \(project:w or \(sprint:$(date +%-V) \(+A or +O\)\) \) "$*"}

or has to be lowercase, brackets in taskwarrior’s filtering have to be escaped.

Google sheets linking between spreadsheets

Use a formula like this:

=IMPORTRANGE("https://docs.google.com/spreadsheets/d/1xrGsOD-yXuORqd8cFg21XOo3ZIw9QbSiNDcnSEatlPM/edit#gid=0", "Sheet1!A:A") ¹ For me it was ; as separator; may need to confirm connecting sheets.

Changed colour of +F tasks to a better shade of gray in .taskrc

Intellij idea structural search and replace

Structural search and replace examples—IntelliJ IDEA is neat! Templates are like this:

$Instance$.$MethodCall$($Parameter$)

Note the “target”, usually it’s set to a complete match, but by call and by params exists too.

I had to disable ideavim, because it was doing some weird formatting by itself with brakets and indents that broke checkstyle.

Filters are also important - $params$ will catch only what.function("one"), but won’t what.function(one, two) - had to change count to be [1, +inf]. (1, not 0, because I needed to avoid replacing what.function().)

“Expression cannot be replaced by non-expression” - if you add a ; at the end of the template, it’s an expression now, and the replacement also needs a ; now.

Java “do nothing” instruction (a la pass)

; works! ¹ A bigger one that makes checkstyle happy is assert true;
