st - simple terminal
--------------------
st is a simple terminal emulator for X which sucks less.
Requirements
------------
In order to build st you need the Xlib header files.
Installation
------------
Edit config.mk to match your local setup (st is installed into
the /usr/local namespace by default).
Afterwards enter the following command to build and install st (if
necessary as root):
make clean install
Running st
----------
If you did not install st with make clean install, you must compile
the st terminfo entry with the following command:
tic -sx st.info
See the man page for additional details.

# st - simple terminal
st is a simple terminal emulator for X which sucks less.
## Notes about this fork
This is a fork of st, the original repo can be found here: [https://git.suckless.org/st/](https://git.suckless.org/st/)
The original st webpage is here: [https://st.suckless.org/](https://st.suckless.org/)
### Available patches
* [Alpha](https://st.suckless.org/patches/alpha/) : This patch allows users to change the opacity of the background. Note that you need an X composite manager (e.g. compton, xcompmgr) to make this patch effective.
* [Clipboard](https://st.suckless.org/patches/clipboard/) : This trivial patch sets CLIPBOARD on selection.
* [font2](https://st.suckless.org/patches/font2/) : This patch allows to add spare font besides default.
* [Wide glyph](https://st.suckless.org/patches/glyph_wide_support/) : This patch allows to display the full glyph instead of it being cut off. See also [here](https://github.com/LukeSmithxyz/st/pull/349)
#### Colorscheme patch
The colorscheme patch is a custom patch, it is not the ones from [colorscheme](https://st.suckless.org/patches/colorschemes/)
It is `solarized.dark` exported from https://terminal.sexy with a different bg and fg color.
Also the `defaultfg`, `defaultbg` and `defaultcs` are not `static`s, otherwise it won't compile.
### Previous available patches
* [Fix Keyboard Input](https://st.suckless.org/patches/fix_keyboard_input/) : Add a few previously undefined keys.
Removed as this was used for additional keys for zooming.
### Applying/Removing Patches
Applying patches from this repository use:
- applied all at once without committing:
```
git apply patches/*
```
- applied as individual commits
```
git am patches/*
```
Applying patches from https://st.suckless.org/patches/ use:
```
# Add custom patch
patch -Np1 -i patches/custom.diff
or
patch < patch.diff
# Remove st-alpha-201806-16-0.81 patch
patch -R patches/st-alpha-20180616-0.8.1.diff
```
## Requirements
In order to build st you need the Xlib header files.
## Installation
Edit config.mk to match your local setup (st is installed into
the /usr/local namespace by default).
Afterwards enter the following command to build and install st (if
necessary as root):
```bash
make clean install
```
## Running st
Start `st` from a launcher like dmenu or rofi.
If you did not install st with make clean install, you must compile
the st terminfo entry with the following command:
```bash
tic -sx st.info
```
See the man page for additional details.
