This is the home of my fetch script! This script gathers info <br />
|
|
about your system and prints it to the terminal next to an image of your choice!

<!-- Features {{{ -->
|
|
|
|
|
|
## Features
|
|
|
|
|
|
- **Supports Linux, Mac OS X and Windows (Cygwin)!**
|
|
- If the script isn't working on your system open an issue.
|
|
- *BSD support is currently in testing! See issue #10
|
|
- **It's Fast**
|
|
- The script makes heavy use of bash builtins and <br \>string manipulation.
|
|
- **Display an image next to the info. (or don't!)**
|
|
- The script can use your current wallpaper, shuffle through a directory or just <br \>display an image of your choice.
|
|
- The wallpaper function on linux uses feh, It's hard to add support <br \>
|
|
for other wallpaper setters as they don't provide a way of getting <br \>
|
|
the current wallpaper from the cli.
|
|
- **Highly Customizable**
|
|
- You can customize almost everything.
|
|
- See Usage below or lines 23-233 in script
|
|
- **Take a screenshot at the end.**
|
|
- It's disabled by default and you can specify the cmd <br \>to use with `--scrotcmd cmd` at launch or by <br \>changing the value of `$scrotcmd` in the script.
|
|
- **Smart crop (or Waifu crop)**
|
|
- See https://github.com/dylanaraps/fetch/wiki/What-is-Smart-Crop%3F

## Dependencies
|
|
|
|
|
|
#### Required dependencies:
|
|
|
|
- Bash **4.0+**
|
|
- For those of you on OS X not wanting to update bash, the script <br \>also works with zsh. All you have to do is change the shebang at <br \>the top to `#!/bin/zsh`.
|
|
- Text formatting, dynamic image size and padding: `tput`
|
|
- Uptime detection: `procps` or `procps-ng`
|
|
|
|
#### Optional dependencies:
|
|
|
|
All OS:
|
|
|
|
- Displaying Images: `w3m`
|
|
- You may also need `w3m-img`
|
|
- Image Cropping, Resizing etc: `ImageMagick`
|
|
- Current Song: `mpc`
|
|
- Resolution Detection: `xorg-xdpyinfo`
|
|
- Window manager detection: `wmctrl`
|
|
- This is used as a fallback to parsing `.xinitrc` and `$XDG_CURRENT_DESKTOP`.
|
|
- Take a screenshot on script finish: `scrot`
|
|
- You can change this to another program with a `--scrotcmd` and an in script option.
|
|
|
|
Linux | \*BSD:
|
|
|
|
- Display Wallpaper: `feh`

|
## Post Install
|
|
|
|
|
|
**NOTE:** For the images to be sized correctly you need to set the `$font_width` variable.
|
|
If you don't know your font width in pixels keep trying values until the image is sized correctly.
|
|
|
|
You can also use the launch flag `--font_width` to set it on the fly.
|
|
|
|
You can customize what info to print by editing the info array near the top of the script.
|
|
The array looks like this:
|
|
|
|
```sh
|
|
info=(
|
|
"gettitle"
|
|
"underline"
|
|
"OS: getdistro"
|
|
"Kernel: getkernel"
|
|
"Uptime: getuptime"
|
|
"Packages: getpackages"
|
|
etc...
|
|
)
|
|
```
|
|
|
|
See these comments inside the script for more info:
|
|
https://github.com/dylanaraps/fetch/blob/master/fetch#L29
|
|
|
|
If you don't want to edit the script you can customize everything using flags at launch!
|
|
|
|
Here's what my fetch alias looks like:
|
|
|
|
```sh
|
|
alias fetch2="fetch \
|
|
--block_range 1 8 \
|
|
--line_wrap off \

## Issues and Workarounds
|
|
|
|
|
|
#### The image is rendering with black lines in Urxvt while using an xft font.
|
|
|
|
This is an issue with w3mimgdisplay and not the script. You can find a workaround here:
|
|
|
|
https://github.com/hut/ranger/issues/86#issuecomment-17346249
|
|
|
|
|
|
#### The text is too long for my terminal window and wraps to the next line causing the image to not render correctly.
|
|
|
|
There are a few ways to fix this.
|
|
|
|
* Disable line wrapping with `$line_wrap off` in the script or with the launch flag `--line_wrap off`
|
|
|
|
* The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can <br \>
|
|
enable them by changing these variables or using these flags.
|
|
|
|
```sh
|
|
# In script options
|
|
$uptime_shorthand on
|
|
$gtk_shorthand on
|
|
|
|
# Launch flags
|
|
--uptime_shorthand on
|
|
--gtk_shorthand on
|
|
```
|
|
|
|
* Edit the info array to make the subtitles shorter
|
|
|
|
* Resizing the terminal so that the lines don't wrap.
|
|
|
|
|
|
#### [Linux] The script hangs and doesn't display anything
|
|
|
|
This is caused by the getwallpaper function failing to find your current wallpaper and <br \>
|
|
imagemagick trying to crop a nonexistent image. You can fix this by installing feh and using it<br \>
|
|
to set your wallpaper or by changing the image source.
|
|
|
|
You can change the source by editing the `$image` variable or by launching the script with `--image`.
|
|
|
|
The possible values are:
|
|
|
|
* **wall** - Use the current wallpaper. (Default)
|
|
* **shuffle** - Shuffle through images in a directory. See `$shuffledir`
|
|
* **path/to/img.png** - Select an image to display.
|
|
* **off** - Disable images

## TODO
|
|
|
|
Here's what's on my todo list
|
|
|
|
- Add Windows resolution detection
|
|
|
|
- Look into iterm2 image rendering
|
|
|
|
- Cleanup of info array handling
|
|
|
|
- Imagemagick optimizations
|
|
|
|
- More info outputs. Now that it's easy to customize what's printed and<br \>
|
|
everything is a function we can add optional support for pretty much anything.
|
|
|
|
- Resolution (Done!)
|
|
- GTK themes (Done!)
|
|
- Terminal Font
|
|
- GPU
|
|
- IP
|
|
- etc
