# fetch.sh
|
||||
|
||||
This is the home of my fetch script! This script gathers info <br\>
|
||||
about your system and prints it to the terminal.
|
||||
|
||||
I've spent the past few days rewriting this and it now supports <br\>
|
||||
other distros as well as a ton of new features and bug fixes.
|
||||
|
||||
If you're having any issues or have any ideas, please open an issue! <br\>
|
||||
I can't test on many other distros and I want this to work <br\>
|
||||
for as many people as possible.
|
||||
|
||||
|
||||
|
||||
|
||||
## Dependencies
|
||||
|
||||
These are the script's dependencies:
|
||||
|
||||
- Displaying Images: w3m
|
||||
- Image Cropping: ImageMagick
|
||||
- Display Wallpaper: feh
|
||||
- Current Song: mpc
|
||||
|
||||
These are the script's optional dependencies
|
||||
- Window Manager Detection: wmctrl
|
||||
- You can manually set this at launch with:
|
||||
|
||||
```scrot.sh --winman string```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
usage: scrot.sh [--colors 1 2 4 5] [--kernel "$(uname -rs)"]
|
||||
|
||||
Info:
|
||||
--title string Change the title at the top
|
||||
--distro string/cmd Manually set the distro
|
||||
--kernel string/cmd Manually set the kernel
|
||||
--uptime string/cmd Manually set the uptime
|
||||
--packages string/cmd Manually set the package count
|
||||
--shell string/cmd Manually set the shell
|
||||
--winman string/cmd Manually set the window manager
|
||||
--cpu string/cmd Manually set the cpu name
|
||||
--memory string/cmd Manually set the memory
|
||||
--speed string/cmd Manually set the cpu speed
|
||||
--song string/cmd Manually set the current song
|
||||
|
||||
Text Colors:
|
||||
--colors 1 2 3 4 Change the color of text
|
||||
(title, subtitle, colon, info)
|
||||
--titlecol num Change the color of the title
|
||||
--subtitlecol num Change the color of the subtitle
|
||||
--coloncol num Change the color of the colons
|
||||
--infocol num Change the color of the info
|
||||
|
||||
Color Blocks:
|
||||
--printcols start end Range of colors to print as blocks
|
||||
--nopal Disable the color blocks
|
||||
|
||||
Image:
|
||||
--image Image to display with the script
|
||||
The image gets priority over other
|
||||
images: (wallpaper, \$img)
|
||||
--size px Change the size of the image
|
||||
--padding How many spaces to pad the text
|
||||
to the right
|
||||
--xoffset px How close the image will be
|
||||
to the left edge of the window
|
||||
--yoffset px How close the image will be
|
||||
to the top edge of the window
|
||||
--noimg Disable all images
|
||||
--nowall Disable the wallpaper function
|
||||
and fallback to \$img
|
||||
--clean Remove all cropped images
|
||||
|
||||
Other:
|
||||
--help Print this text and exit
|
||||
|
||||
|
||||
## TODO
|
||||
|
||||
Here's what's on my todo list
|
||||
|
||||
- Add an easy way to define info prefixes at launch.
|
||||
- Find a reliable way to set the text padding dynamically. I can get this to
|
||||
<br/> work based on font width but there's no reliable way of getting
|
||||
<br/> fontwidth for every terminal afaik.
|
||||
- Find a quick and reliable way to get the current window manager. I had a
|
||||
<br/> solution that used an array of processes and pgrep but it doubled the
|
||||
<br/> startup time for the script.
|
||||
|
||||
If you've got any ideas on how to solve these problems, let me know!
|
||||
|
||||
|
||||
## Customization
|
||||
|
||||
I launch fetch using a shell function and a ton of flags. Here's how it looks:
|
||||
|
||||
```sh
|
||||
fetch () {
|
||||
fetch.sh \
|
||||
--printcols 1 7 \
|
||||
--cpu "AMD FX-6300" \
|
||||
--song "$(mpc current | cut -c 1-30)" \
|
||||
--uptime "$(uptime -p | sed -e 's/minutes/mins/')" \
|
||||
--title "dylan's pc" \
|
||||
$@
|
||||
}
|
||||
```
|
||||
|
||||
Notice how you can even pass commands? This allows you to easily use custom
|
||||
<br/> commands or even just bare strings to change the info.
|
||||
|
||||
|
||||
## Screenshots
|
||||
|
||||
#### The color script is now builtin.
|
||||
|
||||
|
||||
#### You can now customize the color of everything.
|
||||
|
||||
|
||||
#### You can now disable all images with a flag.
