st-patches
==========
A personal set of st configuration and patches because why the fuck not.
Includes:
* [st-boxdraw_v2-0.8.2.diff](https://st.suckless.org/patches/boxdraw/) - draw beautiful pseudo graphic lines instead of whatever your font provides
* st-bright-bold-text.patch - make non-colored bold text brigh
* st-disable-bold-italic-fonts.patch - actually disable bold, italic or bold italic font styles
* st-disable-intensity-styles.patch - disable so called "intensity styles", do not make colored bold text bright
* makest - a simple script to apply all the patches and build st
* config.h - my config

Subject: [PATCH] boxdraw: custom-draw U+25XX lines/blocks to align seamlessly
Date: Wed, 26 Dec 2018 14:51:45 +0200
Subject: [PATCH] boxdraw_v2: custom render lines/blocks/braille for perfect
alignment
It seems impossible to ensure that blocks and line drawing glyphs
align without visible gaps for all combinations of arbitrary font,
size and width/height scale factor.
This commit adds an option to custom-draw (without using the font)
most of the lines/blocks codepoints such that they're rendered
identically (per size) and align perfectly regardless of font, size
or chscale/cwscale configuration values.
This commit adds options to render most of the lines/blocks and
braille codepoints without using the font such that they align
perfectly regardless of font, size or other configuration values.
138 shapes are supported (U+2500 - U+259F except dashes, diagonals
and shades), composited as 16-bit values at boxdraw_data.h .
Supported codepoints are U+2500 - U+259F except dashes/diagonals,
and U28XX.
See links and references at boxdraw_data.h
The lines/blocks data is stored as 16-bit values at boxdraw_data.h
boxdraw/braille are independent, disabled by default at config[.def].h
