Building from source

[alexmyczko]

When trying to build from source, on Debian sid I get this output:

$ cd build
$ mkdir svgs    # this is not documented anywhere
$ ./gen_glyphs.sh
Step 1Program root: /usr
Failed to find NameList: TT
Internal Error: Invalid 2nd order spline in SplineRefigure2

Maybe a build script/system would be good?

ah much better after replacing all python3.8 with python3.11 and pip install python-gegl

On Ubuntu 24.04 it is pretty difficult to run the build scripts.

The main issue is to get a gimp AppImage to work with python interpreter and Gegl. The closest working gimp with python interpreter is the Flatpak gimp version, but it is missing Gegl-0.4.typelib which is found in DEB package gir1.2-gegl-0.4.

The Ubuntu 24.04 gimp does not have python2 nor python-fu.

Rumors say that gimp 3.00 is supposed to have python-fu.

Here are some notes on what I tried on Ubuntu 24.04:

mkdir $HOME/src
cd $HOME/src
git clone https://github.com/ctrlcctrlv/TT2020.git
cd TT2020/build
mkdir svgs pngs styleR

sudo apt-get install gegl python3-pip python3-virtualenv parallel fontforge python3-fontforge gimp-python inkscape gir1.2-gegl-0.4

# Ubuntu 24.04 blocks easy install of pip packages
# https://linuxways.net/ubuntu/install-pip-use-on-ubuntu-24-04/

sudo mkdir /home/tt2020
sudo virtualenv --system-site-packages /home/tt2020

# Fix permissions
sudo chown -R $USER /home/tt2020

# Activate virtual environment tt2020
source /home/tt2020/bin/activate

# activating a virtualenv gives you a shell function named:
#     deactivate
# to exit the virtual environment

pip3 install python-gegl

# Download GIMP_AppImage-release-2.10.8-withplugins-x86_64.AppImage from https://github.com/aferrero2707/gimp-appimage/releases
# This appimage does not seem to have gegl functionality.

PREVIOUSDIR=$(pwd)
cd $(xdg-user-dir DOWNLOAD)
GIMP_APPIMAGE="GIMP_AppImage-release-2.10.8-withplugins-x86_64.AppImage"
wget "https://github.com/aferrero2707/gimp-appimage/releases/download/continuous/$GIMP_APPIMAGE"
chmod +x "$(xdg-user-dir DOWNLOAD)/$GIMP_APPIMAGE"
cd "$PREVIOUSDIR"

# Flatpak gimp has python-fu
# flatpak install gimp

# Style R is supposed to mimic uneven stroke speed resulting in something similar bold as Style E when hit hard and a half as bold font when the stroke is weaker.

cp styleE.sh styleR.sh
cp styleE.py styleR.py

# Change styleR.sh to:
# ALT="$3" SEED=$((100000+$2+($4-1))) GIMPIMAGE="$1" /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=gimp-2.10 --file-forwarding org.gimp.GIMP -idf --batch-interpreter=python-fu-eval -b - < styleR.py

# One idea to simulate uneven strokes is to change line 28 in styleR.py to:
# gauss_factor = random.randrange(10, 40, 5)
# pdb.plug_in_gauss(im, im.active_drawable, gauss_factor, gauss_factor, 0)

# Change line 44:
# pdb.gimp_brightness_contrast(new_mask, 47, 84)
# to:
# pdb.gimp_brightness_contrast(new_mask, round(gauss_factor/40*47), round(gauss_factor/40*84))

# gen_glyphs.sh needs some adjustment. Change line 5 to:
# ls svgs/* | parallel --progress 'inkscape -z {} --export-png=pngs/{/.}.png -d 600'

./gen_glyphs.sh

# Directory svgs and pngs should now have 482 files each

./gen_style.sh R 1 9

# The script will typically fail in "gen_cell_noise.py"

# python-gegl module is believed to work with python3, but has not been tested.

I think I need help to get it work.
