function_printer

西电编译原理大作业——函数绘图语言解释器，使用libSDL2绘图

Usage

Usage: function_printer [-h] [-W Width] [-H High] <FILE>

build

推荐使用Visual studio 2022进行构建，当然不用也无所谓

Windows

Use Cmake

Do the following in the project root directory：

1. mkdir build

2. cd build

3. cmake ..

4. Open function_printer.sln in visual studio then build it.

Use Visual studio

Open the project folder in visual studio and build.

Notice

1. The output files is located in the /bin directory

2. Before running the program, please ensure that it is located in the same directory as bin/SDL2.dll

Linux

Use Cmake

1. install libSDL2：

sudo apt install libsdl2-dev
sudo apt install libsdl2-image-dev
sudo apt install libsdl2-mixer-dev
sudo apt install libsdl2-ttf-dev
sudo apt install libsdl2-gfx-dev

Do the following in the project root directory：

2. mkdir build

3. cd build

4. cmake ..

5. make

Notice

1. The output files is located in the /bin directory

2. If your system cannot use package manager (like apt) to install libsld2, try building and installing from the source code: Downdlow Source Code.

Test Case

test.funcs

rot is 0;
origin is (50, 400);
scale is (2, 1);
for T from 0 to 300 step 0.01 draw (t, 0);
for T from 0 to 300 step 0.01 draw (0, -t);
for T from 0 to 300 step 0.01 draw (t, -t);
scale is (2, 0.1);
for T from 0 to 55 step 0.01 draw (t, -(t*t));
scale is (10, 5);
for T from 0 to 60 step 0.01 draw (t, -sqrt(t));
scale is (20, 0.1);
for T from 0 to 8 step 0.01 draw (t, -exp(t));
scale is (2, 20);
for T from 0 to 300 step 0.01 draw (t, -ln(t));
