Background

In Customized Archetype for This Site, I was using

{{ slicestr .Name 11 | humanize | title }}

in the title attribute in my site’s archetypes/default.md, so that the first 11 characters (YYYY-MM-DD-) would be taken out if I type this command.

$ hugo new post/$(date -I)-<MY_POST_TITLE>.md

In practice, <MY_POST_TITLE> can be replaced to any title, like my-post-title.

Problem

I wanted to create my IntelliJ cheatsheet, so I typed this command.

We’ll try to stay in the project root if possible.

Find all non-hidden files to know the file structure.

$ find -path './.*' -prune -o -type f -print
./Algo-init.iml
./out/production/Algo-init/fr/eql/ai114/algo/init/demo/_1_HelloWorld.class
./src/fr/eql/ai114/algo/init/demo/_1_HelloWorld.java

• -prune returns true for the chosen path and prevents find from descending.

• -o means OR, so the paths matching -prune won’t pass through -o.

• -type f selects files, not folders.

• By default, AND is used to connect different conditions.

Background

We often want to test the output with different values for a parameter. Here’s an example: we have a parameter that pandoc uses to / compile source code files to PDF / M$ Word / etc.

rm output.html; param=0; pandoc input$param.txt -o output.html; \
echo param = $param

In practice, a parameter can be a font, the font size, etc, and there can be multiple parameters.

Background

I’m writing my guide for preparing simple documents. I hope that users can prepare documents efficiently and the prepared documents look smart.

Problem

To help readers get my message in the linked guide, I used many icons from Font Awesome. However, it doesn’t include pandoc’s logo. I tried searching that using the search string “pandoc logo filetype:svg”. Duckduckgo couldn’t find any results. Luckily, Google found many SVGs. The first result linked to a relevant discussion on Google Groups. However, all posts were collapsed, and the desired SVG didn’t show up.

Problem

I have unprotected

1. input1.pdf
2. input2.pdf

and I want to create one single encrypted.pdf.

My try

I looked up QPDF’s manual and tried the following command.

qpdf --empty --pages input{1,2}.pdf --encrypt upw opw 256 -- encrypted.pdf

but I got this error.

qpdf: unrecognized argument --encrypt (pages options must be terminated with --)

For help:
  qpdf --help=usage       usage information
  qpdf --help=topic       help on a topic
  qpdf --help=--option    help on an option
  qpdf --help             general help and a topic list

Background

On M$ Win*, I don’t have dedicated PDF readers like Adobe.

During visioconference, one might want to share some downloaded PDFs. Those documents can be part of an ebook or notes. In some situations, they can provide context to a discussion.

Problem

1. Under the same folder, you might have

• downloaded_ebook.pdf
• personal_info.pdf
• other_personal_stuff.pdf that you don’t want to expose while streaming.

However, each downloaded PDF usually comes with a name set by others. It can be tedious to rename them according to your own habits. To protect users’ privacy, we can

Goal

Make the characters larger and more readable.

Solution

The option names might be found in the manual. Sometimes, I find opening MINGW’s settings through GUI helpful.

FontHeight=12
Columns=143
Rows=36

I’ve read Gerald Lee’s .minttyrc. I’ve enlarged the window size so that in the standard output, one line can contain more info.
