ENV PATH="/usr/local/julia/bin:${PATH}"

ADD ./requirements.txt /pysr/requirements.txt
RUN pip3 install --no-cache-dir -r /pysr/requirements.txt

# Install PySR:
# We do a minimal copy so it doesn't need to rerun at every file change:
ADD ./pyproject.toml /pysr/pyproject.toml
ADD ./setup.py /pysr/setup.py

RUN mkdir /pysr/pysr
ADD ./pysr/*.py /pysr/pysr/
ADD ./pysr/juliapkg.json /pysr/pysr/juliapkg.json

RUN mkdir /pysr/pysr/_cli
ADD ./pysr/_cli/*.py /pysr/pysr/_cli/

RUN mkdir /pysr/pysr/test

# Now, we create a custom version of SymbolicRegression.jl
# First, we get the version from juliapkg.json:
RUN python3 -c 'import json; print(json.load(open("/pysr/pysr/juliapkg.json", "r"))["packages"]["SymbolicRegression"]["rev"])' > /pysr/sr_version

# Remove v from the version:
RUN cat /pysr/sr_version | sed 's/^v//g' > /pysr/sr_version_processed

# Now, we check out the version of SymbolicRegression.jl that PySR is using:
RUN git clone -b "v$(cat /pysr/sr_version_processed)" --single-branch https://github.com/MilesCranmer/SymbolicRegression.jl /srjl

# Edit SymbolicRegression.jl to create a new function.
# We want to put this function immediately after `module SymbolicRegression`:
RUN sed -i 's/module SymbolicRegression/module SymbolicRegression\n__test_function() = 2.3/' /srjl/src/SymbolicRegression.jl

# Edit PySR to use the custom version of SymbolicRegression.jl:
ADD ./pysr/test/generate_dev_juliapkg.py /generate_dev_juliapkg.py
RUN python3 /generate_dev_juliapkg.py /pysr/pysr/juliapkg.json /srjl

# Install and pre-compile
RUN pip3 install --no-cache-dir . && python3 -c 'import pysr'
