示例

'''
Given a rock with mass $m_{rock}$ thrown by a force of $F_0$ acting over a duration $dt_{force}$,
calculate its airtime and the max height it achieves.
'''

''' Given: '''
g = 9.81 m/s^2
m_{rock} = 10 kg
F_0 = 1000 N
dt_{force} = 0.1 s


''' Solution: '''
y_{vel} = F_0 / m_{rock} * dt_{force} = ?

airtime = y_{vel} / g * 2 = ?
height_{max} = y_{vel} * airtime / 4 = ? cm

输出结果

''' 
CalcuLaTeX:

Write an expression followed by = ? to evaluate it:
'''

50 g + 1 kg = ?

'''
You can suggest a unit if it outputs the wrong one. \\
Make sure it's correct otherwise the document won't \\
compile!
'''

5 m/s^2 * 3 kg = ?
5 m/s^2 * 3 kg = ? N

'''
Assign variables with =
'''
x = 5
y = 10 kg
x * y = ?
z = x kg + y = ?

'''
Set the output digits or use scientific notation \\
by using !digits \{n\} or !scientific 
'''

1 / 3 = ?

!digits 10
1 / 3 = ?

!digits 1
!scientific
1 kg = ? mg

'''
Basic mathematical trig functions are supported (with more to come).

Additionally, builtin constants include $\pi$ and $e$.
'''

sin(\pi) = ?
cos(\pi) = ?
e = ?

CLI 使用方法

假设二进制文件名为 calculatex，运行 calculatex [input] [output.pdf] 将监视 input 文件，并在更改时输出到 output.pdf。这主要用于与实时更新的 PDF 查看器一起使用。

要运行 CalcuLaTeX CLI，您还需要 pandoc 和 texlive 安装。

编译

要构建 CalcuLaTeX，您需要一个夜间 Rust 编译器和 Cargo，最好通过 rustup。之后，就像这样

git clone [email protected]:mkhan45/CalcuLaTeX.git
cd CalcuLaTeX

# both of these output to target/release/
cargo build --release # builds the library only
cargo build --features build-binary --release # builds the CLI

贡献

如果您想贡献，请随意打开一个问题或给我发电子邮件。目前的代码库非常混乱，但它足够小，可以很容易理解。欢迎性能建议，但请不要引入任何额外的复杂性。我还没有进行基准测试，但 LaTeX 编译基本上肯定会比解释器慢一个数量级。
