### As of version 2.6.2-1, freetype2-infinality-ultimate comes with
### the "ultimate3" rendering style enabled internally by default.
### It is still possible to use the optional "infinality-settings.sh"
### script to switch between additional built-in rendering schemes and
### create custom ones if necessary. Once modified, "infinality-settings.sh"
### needs to be copied to "/etc/X11/xinit/xinitrc.d/".
###
### There are two levels of customization available to a user:
###
### 1. A set of 7 preconfigured styles selectable by name.

### Available styles:
### ultimate1 <> extra sharp
### ultimate2 <> sharper & lighter ultimate
### ultimate3 <> ultimate: well balanced (default)
### ultimate4 <> darker & smoother
### ultimate5 <> darkest & heaviest ("MacIsh")
### osx       <> Apple OS X
### windowsxp <> MS Windows XP

### If you want to use a style from the list, uncomment the variable below
### and set its name as the value.


export INFINALITY_FT="osx"


### 2. If you want to create a custom style, uncomment the variables below
###    and enter the values of your choice.

### INFINALITY ENVIRONMENT VARIABLES FOR EXTRA RUN-TIME OPTIONS ##
##################################################################
#
# These environment variables require that their respective patches
# from http://www.infinality.net have been applied to the Freetype
# installation you are using.  They will do abolutely
# nothing otherwise!
#

# This file should be copied to /etc/profile.d/ for system-wide
# effects and/or included in ~/.bashrc or ~/.bash_profile for per-user
# effects:
# 
#   . ~/path/to/this/file/infinality-settings.sh
#
# Of course, the per-user settings will override the system-wide
# settings.  Default values indicated below will be used when the
# environment variables below are not defined.
#
# When I say "Default:" below, I'm referring to the default if no
# environment variables are set.  Generally this ends up being
# whatever Freetype's default is set to.

# SET_XFT_SETTINGS
#
# Should the below Xft settings be set globally by this script?  (true/false)

SET_XFT_SETTINGS=true

# XFT settings are like a red-headed stepchild that should be beaten severely.  
# These only affect legacy programs, and *parts* of some modern programs like 
# google-chrome.  We only deal with these settings because we have to, otherwise 
# crap will slip by.  I recommend using hintslight and autohint as the defaults
# normally in /etc/fonts/.  The reason hintfull and autohint:0 is needed here  
# because otherwise some programs will occassionally request slight hinting for 
# a truetype font. When a program does this, Freetype automatically uses the 
# autohinter, when you may actually want it to be rendered with the TT hinter, 
# (if specified in /etc/fonts/).  So setting this to hintfull guarantees that the 
# TT font will be rendered with the TT hinter (assuming it is specified in 
# /etc/fonts/ to be rendered that way.)  For TT fonts that you want 
# rendered with autohint, specifiying that in the /etc/fonts/ 
# should be enough.  But you might think that by setting this to hintfull 
# that it's going to use Freetype's full autohinting (which we *completely* 
# avoid) for fonts you want autohinted.  This is where 
# INFINALITY_FT_AUTOFIT_FORCE_SLIGHT_HINTING comes in.  It tells freetype to 
# use slight hinting on fonts set for autohinting, even if the program requests 
# full autohinting.  Freetype's full hinting only looks OK under certain
# circumstances.  The goal of infinality is to make infinality hinting look 
# good all the time.

# INFINALITY_FT_FILTER_PARAMS
#
# This is a modified version of the patch here:
# http://levelsofdetail.kendeeter.com/2008/12/dynamic_fir_filter_patch.html
#
# Allows you to adjust the FIR filter at runtime instead of at
# compile time.  The idea is to have values add up to 100, and be
# symmetrical around the middle value.  If the values add up to 
# more than 100, the glyphs will appear darker.  If less than 100,
# lighter.  I recommend using this method to make glyphs darker
# or lighter globally as opposed to using the gamma option (see note in 
# the gamma option).
#
# Here are some samples of various filter parameters:
#
# (this has been changed to use integers between 0 and 100 to
#  avoid problems with regional differences like comma for decimal point)
#
#
# Strong Extra Smooth  "15 20 30 20 15"  (extra smooth, natural weight)
# Extra Smooth         "20 20 30 20 20"  (extra smooth, extra weight)
# Smooth               "15 20 32 20 15"  (smooth, natural weight)
# Stronger Gibson      "11 22 38 22 11"  (smooth, extra weight)          
# Gibson               "11 22 33 22 11"  (smooth, natural weight)
# Freetype Light       "00 33 34 33 00"  (sharp, natural weight)         # freetype's "light" LCD filter
# Freetype Default     "06 25 44 25 06"  (sharp, extra weight)           # freetype's default
# Extra Sharp          "00 35 35 35 00"  (extra sharp, extra weight)     # freetype's "light" LCD filter on acid
#
#
# Windows uses something more sharp, maybe along the lines of Freetype's default
#
# Default if no ENV_VARS present:     [Freetype's default]
# Recommended: "11 22 38 22 11"       (too dark / smooth for some)
#
# Example 1:  export INFINALITY_FT_FILTER_PARAMS="11 22 38 22 11"

##################################################################
# INFINALITY_FT_STEM_ALIGNMENT_STRENGTH
#
# This performs analysis on each glyph and determines an amount
# to shift the glyph, left or right, so that it aligns better to
# pixel boundaries.
#
# This results in subtley cleaner looking stems, at the expense of
# proper distances between glyphs.  This is only active for sizes
# 10 px or greater and does not apply to bold or italic fonts.
# 
# There are also exceptions on a small number of fonts that I've
# not been able to render nicely with alignment enabled.  In those
# cases, a forced translation is applied instead.
#
# Possible values:
# 0 through 100 - think of as percentage of strength
# 
# 0 corresponds to no shifting whatsoever.  In other words, OFF.
# 
# 100 corresponds to a full move to a snap zone defined by
#   the snapping algorithm, be it left or right.  This
#   is the full amount any glyph could be moved in order to make it
#   align to the pixel.
#
# Values inbetween act as caps.  If the algorithm determines that it
# wants to move the glyph .33 of a pixel to the left, but the value
# is set to 50 (i.e. 50%), then the maximum move that would be allowed
# is 50% of half a pixel, in other words .25.  So instead of .33 the 
# glyph is moved .25 of a pixel.
#
# For a subtle effect that doesn't dramatically affect the glyph, use
# 25 for this and 25 for INFINALITY_FT_STEM_FITTING_STRENGTH
#
# Default if no ENV_VARS present:     0
# Recommended if you want to use it:   100

export INFINALITY_FT_STEM_ALIGNMENT_STRENGTH=25



##################################################################
# INFINALITY_FT_STEM_FITTING_STRENGTH
#
# This performs analysis on each glyph and determines an amount
# to horizontally scale the glyph, so that stems align better to
# pixel boundaries.  An emboldening (or anti-emboldening) is
# performed afterward to account for stem width exaggeration.
#
# This results in subtley cleaner looking fonts, at the expense of
# proper distances between glyphs and slightly misshapen glyphs.  
# This is only active for sizes 10 px or greater and does not 
# apply to bold or italic fonts.
#
# There are also exceptions on a small number of fonts that I've
# not been able to render nicely with fitting enabled.  In those
# cases, a forced translation is applied instead.
# 
#
# Possible values:
# 0 through 100 - think of as percentage of strength
# 
# 0 corresponds to no stretching whatsoever.  In other words, OFF.
# 
# 100 corresponds to a full pixel stretch, be outward or inward.  This
#   is the full amount any glyph could be stretched in order to make it
#   align to a pixel boundary.  Which direction is chosen is part
#   of the art of what I'm trying to do in the code.  ;)
#
#
# Values inbetween act as caps.  If the algorithm determines that it
# wants to stretch the glyph .75 of a pixel outward, but the value
# is set to 50 (i.e. 50%), then the maximum move that would be allowed
# is 50% of a pixel, in other words .50.  So instead of .75 the 
# glyph is stretched .50 of a pixel.
#
# For a subtle effect that doesn't dramatically affect the glyph, use
# 25 for this and 25 for INFINALITY_FT_STEM_FITTING_STRENGTH
#
# Default if no ENV_VARS present:     0
# Recommended if you want to use it:   100

export INFINALITY_FT_STEM_FITTING_STRENGTH=25



##################################################################
# INFINALITY_FT_STEM_SNAPPING_SLIDING_SCALE
#
# This allows you to set a ppem at which alignment and fitting
# will reach 100%.  As glyphs become larger, more dramatic
# snapping will not affect the glyph shape as much, so it makes
# sense to allow this.  
#
# For fonts that are 10 ppem, the values set above for 
# INFINALITY_FT_STEM_ALIGNMENT_STRENGTH and 
# INFINALITY_FT_STEM_FITTING_STRENGTH will be used.  As the ppem
# gradually becomes larger, so will the strength settings, and
# they will reach 100% at the ppem you specify here.
#
# This is a simple linear scale.
#
# Possible values:
# 0 means to not use this feature
# 
# 11 and up will set the 100% level to that ppem value
#
# Anything else is officially undefined, but I still bound it internally.
#
# Default if no ENV_VARS present:     0

export INFINALITY_FT_STEM_SNAPPING_SLIDING_SCALE=40



##################################################################
# INFINALITY_FT_USE_KNOWN_SETTINGS_ON_SELECTED_FONTS
#
# This applies largely to certain MS fonts, but some others as well.
# it will apply known good settings on a font-by-font basis, regardless
# of the other settings above or below.
#
# - Use known values for selected fonts & ppems that are known to look
# ok with 100:
#
# INFINALITY_FT_STEM_ALIGNMENT_STRENGTH  
# INFINALITY_FT_STEM_FITTING_STRENGTH 
#
# - Use various internal tweaks like compatible widths and other
# font-specific hacks.
# - Use gamma, brightness or contrast adjustments automatically
#     on certain fonts.  Global settings will still apply afterwards.
# - Enable various forced settings on selective fonts during 
#     rasterization and stem_alignment. 
#
# If set to TRUE, this will use 100 regardless of the values you have
# specified above.  It will not affect fonts that are not in this
# small list.
#
# Possible values:
# FALSE means to not use this feature
# 
# TRUE will enable this feature
#
# Default if no ENV_VARS present:     FALSE
# Recommended:  TRUE
#

export INFINALITY_FT_USE_KNOWN_SETTINGS_ON_SELECTED_FONTS=true



##################################################################
# INFINALITY_FT_CHROMEOS_STYLE_SHARPENING_STRENGTH
#
# This enables an algorithm found in ChromeOS for sharpening the
# appearance of glyphs.  It is based off this patch:
#
# http://codereview.chromium.org/3298011/diff/9001/media-libs/freetype/files/freetype-2.3.11-lcd-sharpen.patches
#
# It gives glyphs a more "grainy" look through some gamma
#  correction.  It does tend to thin out vertical stems, which
#  may be a feature or a bug depending on your taste  ;)
# 
#
# Possible values:
# 0 through 100 - think of as percentage of strength
# 
# 0 corresponds to no sharpening whatsoever.  In other words, OFF.
#
# 25 is good for a subtle effect.
#
# 50 corresponds to the default ChromeOS value.
#
# 100 corresponds to maximum sharpening.  This usually results in 
#  something undesirable looking.
#
#
# As you increase this amount, it is good to decrease the gamma (2nd value)
# of INFINALITY_FT_PSEUDO_GAMMA, and possibly increase 
# INFINALITY_FT_STEM_FITTING_STRENGTH and 
# INFINALITY_FT_STEM_ALIGNMENT_STRENGTH, as it seems like the algorithm
# lightens stems that aren't fully on-pixel.
#
# Default if no ENV_VARS present:     0
# Recommended: If you're going to use this filter - 50

export INFINALITY_FT_CHROMEOS_STYLE_SHARPENING_STRENGTH=0



##################################################################
# INFINALITY_FT_WINDOWS_STYLE_SHARPENING_STRENGTH
#
# This enables an algorithm developed with the intention to sharpen
# fonts to look similarly to Windows.
#
# It gives glyphs a more "grainy" look, like the ChromeOS filter
# except it does so more selectively.  This prevents the thinning
# of vertical stems that is noticible when a blanket gamma filter
# like the ChromeOS filter is applied.
#
# I also get a "cleaner" impression from the fonts with this Windows
# style filter.  This filter was done by 100% experimentation,
# and there things that could probably be improved.
#
# Some may argue that I shouldn't be trying to take the shortcomings
# of the MS approach and bring them here.  I disagree, as part
# of freedom is having the right to make your fonts look as
# shitty as you'd like.  
#
# Using this filter does somewhat lessen the need to use stem
# fitting and stem alignment, as glyphs appear sharper.
#
# This setting can be used at the same time as the previous chromeOS
# sharpening, and happens after it in the code.
#
#
# Possible values:
# 0 through 100 - think of as percentage of strength
# 
# 0 corresponds to no sharpening whatsoever.  In other words, OFF.
#
# 10-25 is good for a subtle effect while not completely decimating glyphs.
#
# 50-75 corresponds to probably something in the range that Windows uses. 
#
# 100 corresponds to maximum sharpening.  
# 
#
# Using a high value for this variable along with enabling the
#  fringe filter (below) almost eliminates the need
#  for INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT to be set to 100,
#  and can instead be set at 0.  (Setting 
#  INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT to 0 prevents missing
#  stems in the middle of s.  The drawback is that many fonts just look
#  way too sharp and grainy at this setting.  Your call.)
#
# Default if no ENV_VARS present:              0
# Recommended if you want to use this filter:  65

export INFINALITY_FT_WINDOWS_STYLE_SHARPENING_STRENGTH=10



##################################################################
# INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT
#
# When using autohinting, horizontal stems you'd find in E, f, T, -, 
# etc. are normally not snapped to full integer pixel heights, meaning
# that you will get a semi-dark fringe on these stems, above or
# below the black line of pixels:
#
# ##########
# ##
# ##-------
# #########
# ##
# ##--------
# ##########
#
# (- represents the semi-dark pixels)
#
# Setting this to 100 will force integer pixel heights.  Setting it to
# zero will do what Freetype does by default.  Anything inbetween will
# act as a weighted average of the two.  
#
# This is disabled when the standard width is found (via voodoo) to be
# less than 1 pixel, in order to prevent the vanishing stem issues on
# letters with diagonal stems like a and s. 
#
# Under most circumstances, this should be set at 100.  If you choose to
# not set it to 100, you may want to set INFINALITY_FT_FRINGE_FILTER_STRENGTH
# to a non-zero value in order to reduce fringing.
#
#
# Possible values:
# 0              - default Freetype value
# 100            - a full pixel
#
#
# Default if no ENV_VARS present:     0
# Recommended:                        100

export INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT=100



##################################################################
# INFINALITY_FT_USE_VARIOUS_TWEAKS
#
# - Force autohint when no TT instructions present.
# - Artificially embolden horizontally only.
# - When artificially emboldening, maintain the glyph width.
# - Embolden light and thin-stemmed glyphs automatically.
# - Don't sharpen italics. 
#
# Some fonts look bad when stem aligned at certain ppems, no matter
# what. I've put exceptions in to deal with these, included in
# these tweaks.  Georgia and Lucida Grande are examples.
#
#
# Possible values:
# true             - enable tweaks
# false            - do not enable tweaks (do Freetype default)

##################################################################
# INFINALITY_FT_GAMMA_CORRECTION
#
# This does a weighted gamma correction at the LCD filter phase
# PRIOR to the LCD filter.  Unfortunately it does not however
# take into account the color on which the glyph is being rendered
# (or for that matter the color of the glyph),
# which would need to happen in X rendering.  It is actually
# using the gamma function in calculations though.
#
# The first value indicates a px value, the second indicates a
# "gamma" value.  All sizes less than the px value will be corrected
# on a weighted scale based on the second value.
#
# The gamma value is commonly between 0.0 and 3.0.  Due to localization
# issues, the gamma value should be specified as it's actual value
# multiplied by 100.  So a gamma of 1.3 would be 130.  In practice,
# I'd stay between 40 and 250.
#
#
# Values 1 through 100 will darken the glyph
# Values greater than 100 will lighten the glyph
#
#
# Example 1:  Darken glyphs that are less than 10 px. With some fonts
#             even 5 or 6px is readable!
# export INFINALITY_FT_GAMMA_CORRECTION="10 60"
#
# Example 2:  Lighten all glyphs (below 100px)
# export INFINALITY_FT_GAMMA_CORRECTION="100 150"
#
# Example 3:  Do nothing
# export INFINALITY_FT_GAMMA_CORRECTION="0 100"
#
# Default:     [No gamma correction]

export INFINALITY_FT_GAMMA_CORRECTION="0 100"



##################################################################
# INFINALITY_FT_BRIGHTNESS
#
# This filter adjusts brightness, using the standard algorithm
# for brightness.  It is applied AFTER the LCD filtering.
#
# For a Windows XP look, set brightness to something and contrast to 50
# This will also tend to increase its sharpness.
# These values are relative and don't really mean anything
# however they are satisfactory for a range of appearances. 
# Another tip is to use a gamma setting of "1000 110" or something
# over 100 to lighten things before processing.
#
# Default if no ENV_VARS present:       0
# Dark XP Experience:                 -25
# Light XP Experience:                 40
#
# Example: export INFINALITY_FT_BRIGHTNESS="-20"

##################################################################
# INFINALITY_FT_CONTRAST
#
# This filter adjusts contrast, using the standard algorithm
# for contrast.  It is applied AFTER the LCD filtering.
#
# For a Windows XP look, set brightness to -25 and contrast to 50
# This will also tend to increase its sharpness.
# These values are relative and don't really mean anything
# however they are satisfactory for a range of appearances. 
# Another tip is to use a gamma setting of "1000 110" or something

# Default if no ENV_VARS present:     0
# Dark or Light XP Experience:        50
#
# Example: export INFINALITY_FT_CONTRAST="50"

export INFINALITY_FT_CONTRAST="0"



##################################################################
# INFINALITY_FT_GRAYSCALE_FILTER_STRENGTH
#
# This filter adjusts subpixel-rendered glyphs toward grayscale.
# Sometimes this is useful in getting a rendering more like
# OSX.  
#
# Range:  Integers 0 through 100
#   0 represents no filtering
#   50 represents halfway between subpixel and grayscale
#   100 represents completely grayscale
#
# Default if no ENV_VARS present:       0
# Recommended, if you want to use it:  30
#
# Example: export INFINALITY_FT_GRAYSCALE_FILTER_STRENGTH="33"

export INFINALITY_FT_GRAYSCALE_FILTER_STRENGTH="0"



##################################################################
# INFINALITY_FT_FRINGE_FILTER_STRENGTH
#
# This filter tries to remove the horizontal fringing that is found on
# default autohinted glyphs (similar to OSX-rendered glyphs).
# For example, an E may be rendered so that the middle horizontal
# stem is 100% black, but also has a horizonal row of pixels above
# it that is at 50% intensity.  This makes the glyph look dirty, 
# however it is technically accurate.  
#

# INFINALITY_FT_AUTOHINT_HORIZONTAL_STEM_DARKEN_STRENGTH
#
# This post-filter darkens horizontal stems that autohint renders as semi-dark.
# Freetype will by default not force stems to render to pixel boundaries
# because it results in "vanishing stems".  This happens on things like 
# s S a and other glyphs with center diagonal stems.  
#
# If you have INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT set to 100,
# you're telling it to force pixel boundaries, which can result in the
# vanishing stems.  To get around this problem,  I internally override the
# INFINALITY_FT_AUTOHINT_SNAP_STEM_HEIGHT setting if the stem width
# is less than a full pixel, regardless.  This causes semi-dark stems, but
# at least there are stems there.
#
# This filter is intended to darken those semi-dark stems.  I highly 
# recommend using this, but setting to a low value like 10, because
# it is particularly sensitive right now, and can make thin fonts
# look weird otherwise.
#
#
# Range:  Integers 0 through 100
#   0 represents no darkening
#   50 represents a 50% increase toward 1 pixel in height
#   100 represents a full pixel of height
#
#
# Default if no ENV_VARS present:       0
# Recommended, if you want to use it:  10
#
# Example: export INFINALITY_FT_AUTOHINT_HORIZONTAL_STEM_DARKEN_STRENGTH="10"

export INFINALITY_FT_AUTOHINT_HORIZONTAL_STEM_DARKEN_STRENGTH="10"



##################################################################
# INFINALITY_FT_AUTOHINT_VERTICAL_STEM_DARKEN_STRENGTH
#
# This post-filter darkens vertical stems less than 1 pixel that autohint 
# renders as semi-dark.  This applies mostly to thin fonts like 
# Courier New, Raleway, and fonts with the word "Light" in the title or
# style.  Although what autohint is doing is technically correct, it
# results in a bad looking rendering because it's too light, at small 
# ppems.  This filter tries to correct that. 
#
# There is an aspect of this that is automatic, so it's safer to use
# larger values for this than the above horizontal ENV_VAR.  However
# setting this higher has more impact on thinner fonts.  So, I still
# recommend lower values.
#
#
# Range:  Integers 0 through 100
#   0 represents no darkening
#   50 represents a 50% increase (from current strength) toward 1 pixel
#   100 represents a full pixel of width
#
#
# Default if no ENV_VARS present:       0
# Recommended, if you want to use it:  25
#
# Example: export INFINALITY_FT_AUTOHINT_VERTICAL_STEM_DARKEN_STRENGTH="25"

# INFINALITY_FT_AUTOHINT_INCREASE_GLYPH_HEIGHTS
#
# This will slightly stretch some glyphs vertically between 9px
# and 14px (inclusive).  Some people may find this more
# aesthetically pleasing.  This only applies to fonts that are
# using autohint.  I used to recommend this to be set true, but
# it does mess with some (less popular) glyphs in a nasty way.
#
# The goal here is to increase the height of some fonts by 1 px
# but leave the x-height where it is.  Arial is a good example
# of this working properly.  Compare the heights of Arial, Times
# and Freesans with this on, vs. TT hinted versions of Arial and
# Times.

it looks like your chromium font rendering has gamma correction/alpha bleeding enabled. how did you do that? are you patching the skia then compile your own build? thanks.

It seems like Chromium relies on Gtk, which relies on freetype2. I just use the custom freetype2 library (available from the link above) and the config (in this gist). Skia is not patched on my system.

that is weird. because i noticed your github html hyperlink color is violet on your chromium screenshot pic. yeah, freetype2 and macos/windows font rendering engine they all don't have ability to do gamma correction, they're all relying their own low graphic library api, gtk relies cairo (also pixman), firefox/chromium relies skia.
now i guess maybe you just use a css theme on your github. but thanks again for your info.

also here is more info.

I am really not an expert on what library Chromium relies on, but I use only the infinality-remix patches for freetype2 and cairo and the config from this gist, nothing more. I can show some outputs and numbers, if You ask.

The images in Your link are broken, so I cannot figure out what the issue is about.

Also, I do not actually know what the gamma correction features does, subjectively it makes text somewhat brighter. And it seems like this feature is present in the patches:

export INFINALITY_FT_GAMMA_CORRECTION="0 100"

Nice, was looking to improve my current infinality options and found this. Turns out you found very similar parameters to mine! I'm using a bit less emboldement to preserve a bit more of glyphs original intent though but I can see how it could help specially in browser pages with small fonts, that tend to really weak and thin on Linux browsers.

Hey everyone! I have made a small patch for the new freetype to make the fonts look thin and crisp as in the config with no infinality Stay tuned, gist updates are coming.

​Why my fonts are flattened and poorly defined... PLEASE HELP😢

@Cabus1982, hey! It's nice to see you have reached out. It all depends on your configuration. I am assuming you have vanilla Manjaro. In such case the infinality-remix patches are not going to work, because they are outdated. What I could provide you with is a patched freetype library for your system with emboldening enabled, it will make the fonts looking closer to what you have in Windows. Gotta ping you back during the next ~48 hours.

Hello, thanks for answering. I use Manjaro 5.15 LTS and with freetype fonts installed. I tried the infinality-remix, but they look the same...

Here is what can I offer in terms of look (I don't have Arial, this is the default font Cantarell and Cascadia Code)

1. Make sure you are using Gnome (KDE seems to have weird unpleasant defaults that are hard to change)

2. Install the Tweaks tool and make sure you have the Full hinting and LCD smoothing options enabled

It should already make your fonts look better in terms of clarity, but you can go further

3. You can add some horizontal emboldening and change the default LCD filter

This is done by modifying the freetype library - very simple to do by yourself

If you are not ready to edit the source code of the library, I can build a package for you, let me know what architecture you've got in this case

Yes, this will make the fonts look somewhat "incorrect", but pleasant to look and and easy to read

But to me this is ideal if you edit code

@sorenvonsarvort hello, first of all thank you for sharing the settings, I only tweaked a couple of things but generally they look really good. I have one question though, how did you manage to make VSCode apply the changes? On my machine VSCode (to be exact VSCodium) completely ignores my font settings from infinality-settings.sh.

Also, btw, I only have the freetype2-infinality-remix package from the AUR. fontconfig-infinality-remix and cairo-infinality-remix seem to be missing. I'm not sure if this is the cause of the issue.
