# fetch
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!
**NOTE: See this wiki page for info on the new info function and it's usage**

<!-- Features {{{ -->
## Features
- **Supports Linux, Mac OS X, BSD and Windows (Cygwin)!**
- If the script doesn't work on your system, open an issue.
- **It's Fast**
- The script makes heavy use of bash builtins and <br \>string manipulation.
- **Display an image next to the info.**
- Use your current wallpaper, shuffle through a directory or just <br \>display an image of your choice.
- Supports using w3m or iTerm2 to display the images.
- **Display ascii next to the info.**
- Use a file containing ascii art as the image.
- **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

<!-- Dependences {{{ -->
## Dependencies
### Required dependencies:
**All OS:**
- `Bash 4.0+`
**Linux / BSD / Windows:**
- Uptime detection: `procps` or `procps-ng`
### Optional dependencies:
**NOTE:** If `w3m` or `Imagemagick` aren't found then image support will be disabled.
**All OS:**
- Displaying Images: `w3m`
- You may also need `w3m-img`
- **Note:** The script can now also use iTerm2's builtin image rendering instead of w3m!<br \>
Enable it by changing `$image_backend` to `iterm2` or by using the launch flag `--image_backend`.
- Image Cropping, Resizing etc: `ImageMagick`
- More accurate window manager detection: `wmctrl`
**Linux / BSD:**
- Display Wallpaper: `feh`, `nitrogen` or `gsettings`
- Current Song: `mpc` or `cmus`
- Resolution Detection: `xorg-xdpyinfo`
- Take a screenshot on script finish: `scrot`
- You can change this to another program with a `--scrot_cmd` and an in script option.

## Post Install
#### Sizing the image correctly
**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.
#### Customizing what info gets displayed
At the top of the script there's a function that allows you to customize all of the info that gets displayed.
Here's what you can do:
- Add new info lines
- Change the ordering of the info
- Remove unwanted info lines
- Use bash syntax to control when info gets displayed
See this wiki page that goes more in-depth about it:
https://github.com/dylanaraps/fetch/wiki/Customizing-Info
#### Customizing the script using a custom alias
If you don't want to edit the script you can customize almost everything using launch flags!
Here's what my fetch alias looks like:
```sh
alias fetch2="fetch \
--block_range 1 8 \
--line_wrap off \
--bold off \
--uptime_shorthand on \
--gtk_shorthand on \
--colors 4 1 8 8 8 7 \

<!-- Frequently Asked Questions {{{ -->
## Frequently Asked Questions
#### Why doesn't fetch support my wallpaper setter?
It's hard to add support for other wallpaper setters as<br \>
they don't provide a way of getting the current wallpaper from the cli.
If your wallpaper setter **does** provide a way of getting the current wallpaper<br \>
or you know where it's stored then adding support won't be a problem!<br \>

<!-- Issues and Workarounds {{{ -->
## Issues and Workarounds
#### fetch: line 1655: /usr/lib/w3m/w3mimgdisplay: No such file or directory
You're getting this error because the script can't find w3mimgdisplay in it's<br \>
default location. You can fix this by setting the config option `$w3m_img_path`<br \>
to the correct location of w3mimgdisplay.
Other places that `w3mimgdisplay` could located be are:
/usr/lib/w3m/w3mimgdisplay
/usr/libexec/w3m/w3mimgdisplay
/usr/lib64/w3m/w3mimgdisplay
/usr/libexec64/w3m/w3mimgdisplay
#### The image is blank and won't show up.
If the images display in `ranger` and `w3m` then it's an issue with my script and not<br \>
your terminal emulator.
Some terminal emulators don't support viewing images with w3m. You can either disable<br \>
images with `--image off` at launch or `image=off` inside the script.
#### The image is rendering with black lines in Urxvt while using an xft font.
This is an issue with w3mimgdisplay and not the script. You can find a possible workaround here:
https://github.com/hut/ranger/issues/86#issuecomment-17346249
#### The text is too long for my terminal window and wraps to the next line causing the image to not render correctly.
There are a few ways to fix this.
* Disable line wrapping with `line_wrap=off` in the script or with the launch flag `--line_wrap off`
* The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can <br \>
enable them by changing these variables or using these flags.
```sh
# In script options
uptime_shorthand="on"
gtk_shorthand="on"
gpu_shorthand="on"
# Launch flags
--uptime_shorthand on
--gtk_shorthand on
--gpu_shorthand on
```
* Edit the info array to make the subtitles shorter
* Resizing the terminal so that the lines don't wrap.
#### The text is pushed over too far to the right
The easiest way to fix this is to change the value of `--gap` or `$gap`<br \>
to a negative value. For example `--gap -10` will move the text 10 spaces to the left.
#### getgpu doesn't show my exact video card name
If your `lspci | grep "VGA"` output looks like this:
```
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1401 (rev a1)
```
Instead of this:
```
01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)
```
Then you're affected by the issue.
This is caused by your `/usr/share/misc/pci.ids\*` files being outdated and you can fix it<br \>
by running this command as root.
```
sudo update-pciids
```
