Started new job this week and I wanted to have a seprate email on my work related repos then my personal ones. Cool thing is git supports conditional config file includes!

~/.gitconfig

# per-user git config
[user]
name = Travis Shears
email = t@travisshears.com

[includeIf "gitdir:~/company-x/"]
  path = .gitconfig-company-x

~/.gitconfig-company-x

# Company X spefic git config
[user]
name = Travis Shears
email = travis.shears@company-x.com

Now any commits made under the directory ~/company-x will use the email travis.shears@company-x.com and not my personal email.

Recently I was testing an IOS app on my wifes phone. The UI was completly broken. Turns out she had dark mode enabled. That led me down the path of adding dark mode support to the app. Which is testable via the Xcode simulator if you know how to enable it.

Command + Shift + A: Toggles dark mode

Comparing the following shows how to use basename to extract just the file name from a full path.

$ for file in ./content/**/*.md ; do echo $file ; done | head -10
./content/_index.de.md
./content/_index.en.md
./content/_index.ru.md
./content/blog/_index.de.md
./content/blog/_index.en.md
./content/blog/ahrn-valley/index.en.md
./content/blog/archiving-corona-cal/index.en.md
./content/blog/arco/index.de.md
./content/blog/arco/index.en.md
./content/blog/armycookbot/index.de.md


$ for file in ./content/**/*.md ; do file=$(basename $file) && echo $file ; done
_index.de.md
_index.en.md
_index.ru.md
_index.de.md
_index.en.md
index.en.md
index.en.md
index.de.md
index.en.md
index.de.md

Working on my Oblastle game today. In an effort to standardize the way I store images for the game in S3 I needed to move all the files with key image-service/images/oblastle/flags/ to /image-service/images/oblastle/flag/.

Here is how I did it:

$ aws s3 mv s3://travisshears.images/image-service/images/oblastle/flags/ s3://travisshears.images/image-service/images/oblastle/flag/ --recursive --profile personal

source

Where were you –recursive when I was hacking around with for file * ; do aws s3 cp $file…..

$ aws s3 cp ./ s3://travisshears.images/image-service/images/oblastle/context/ --profile personal --recursive
upload: ./us-ak.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-ak.jpg
upload: ./us-co.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-co.jpg
upload: ./us-ar.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-ar.jpg
upload: ./us-ca.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-ca.jpg
upload: ./us-al.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-al.jpg
upload: ./us-ct.jpg to s3://travisshears.images/image-service/images/oblastle/context/us-ct.jpg
...

–recursive is an easy win to upload a bunch of files to s3.

Working on some .png map files today. I needed to covert them to small .jpg’s for uses in Oblastle. Problem being by default the transparent part fills into to black. Here is how to make it white:

$ ls
us-ak.png
us-al.png
us-ar.png
us-az.png
us-ca.png

$ for file in *.png ; do magick mogrify -format jpg -resize '500' -background white -flatten  $file; done

$ ls
us-ak.png
us-ak.jpg
us-al.png
us-al.jpg
us-ar.png
us-ar.jpg
us-az.png
us-az.jpg
us-ca.png

$ rm ./*.png

The important bit being -background white -flatten.

TR is a Unix until to translate characters I recently learned about as part of this awk snippet.

$ echo "TRAVIS" | tr '[:upper:]' '[:lower:]'
travis

source

My first awk snippet! Today I needed to get all the file extensions in directory for a blog post I’m writing.

I solved it with:

$ fd . --type f | awk -F"." '{print $(NF)}' |  tr  '[:upper:]' '[:lower:]' | sort | uniq | pbcopy

Break down

fd . –type f, lists all the files in a directory recursively.

awk -F"." ‘{print $(NF)}’, the -F"." tells awk to split columns on “.”. The ’{print $(NF)’} tells awk to print the last column. Normally you do something like ’{print $2}’ to print the second column.

tr ‘[:upper:]’ ‘[:lower:]’, tr is a Unix until to translate characters. In this case all upper case letters will be translated to lower case. I’ve created a seprate snippet for it as well.

sort | uniq, a classic combo sorts the results then gets rid of duplicates.

pbcopy, anther common one for me pipes the result into the clipboard.

Started playing with garden cli today. After playing around with the local kubernetes deployments I found it annoying it left some system containers running when I was finished. To get rid of these run the following from the project directory (the dir with project.garden.yml)

$ garden delete env

$ garden plugins local-kubernetes uninstall-garden-services

Trying to clean up my laptop a bit today by removing some unused brew packages.

Normally I would use brew list but this also list packages that are dependicies. Here is a way to list the top level packages:

$ brew leaves
asciinema
aspell
autoconf
awscli
bat
bumpversion
...

$ brew uninstall neomutt newsboat travisshears/tap/deploy_tool weechat
...
