采用 pygame 写的象棋程序，目前只完成绘制棋盘与走动棋子，还没考虑规则等问题。
1. 代码：

附： md 批量转换到 pdf 文件
a) 需安装 pandoc， 拷贝 template.tex 到 /usr/share/pandoc/data/templates/ 目录中。
b) 需安装中文字体。
c) 需安装 xelatex.
d) 代码 md2pdfs.py 及模板 template.tex 如下：
from pathlib import Path import os def md2pdfs(currdir='.'): dir = os.path.abspath(currdir) files = os.listdir(dir) for f in files: path = os.path.join(dir, f) if os.path.isdir(path): md2pdfs(path) dir = os.path.dirname(path) continue name = os.path.splitext(f)[0] ext = os.path.splitext(f)[1] if ext == '.md': mdfile = f pdffile = name + '.pdf' os.chdir(dir) print(os.getcwd() + '/' + f) cmd = "pandoc '{0}' -o '{1}' --latex-engine=xelatex -V mainfont='PingFang SC' --template=template.tex".format(mdfile, pdffile) os.system(cmd) if __name__ == '__main__': md2pdfs()

e) 合并 pdf 代码 merge_pdf.py 如下：
# merge_pdf.py # usage: # 复制到目标目录，由终端进入，运行 "python3 merge_pdf.py" 命令即可。 import os from PyPDF2 import PdfFileReader, PdfFileWriter filenames = [] outfile = '../temp.pdf' def getfiles(curr_dir='.', ext='.pdf'): global filenames dir = os.path.abspath(curr_dir) files = os.listdir(dir) for f in files: path = os.path.join(dir,f) if os.path.isdir(path): getfiles(path, ext) continue extname = os.path.splitext(f)[1] if ext == extname: filenames.append(os.path.join(dir,f)) def merge(): getfiles() filenames.sort() writer = PdfFileWriter() pages = 0 for f in filenames: print(f) reader = PdfFileReader(open(f, 'rb')) count = reader.getNumPages() pages += count for i in range(count): writer.addPage(reader.getPage(i)) writer.addBookmark(os.path.basename(f)[:-3],pages - count) stream = open(outfile, 'wb') writer.write(stream) stream.close() print("OK!") def test(dir='.'): dirs = os.listdir(dir) for f in dirs: if os.path.isdir(f): test(f) continue print(f) if __name__ == '__main__': filenames.clear() merge()
