请问有 obsidian 迁移思源的工具吗？

因为凑合用就行，代码比较 ugly，只能参考一下思路吧。主要做了两件事：1）处理了三种 link 形式 [[]] ![]() []()，2）把所有附件都放到了 md 同目录。注意处理前先备份整个 vault。。

import sys
import re
import os
import shutil

pattern_markdown = r'\!\[[^\]]*\]\(([^\)]+)\)'
pattern_wikilink = r'\!\[\[([^\]]+)\]\]'
pattern_pdf = r'\[\[([^\]]+)\]\]'

base_path = '/Path/to/Obsidian/vault/assets'

def replace_markdown(matchobj):
    orig = matchobj.group(0)
    image = matchobj.group(1)
    image_dir = os.path.dirname(image)
    image_filename = os.path.basename(image)
    image_description = ''
    ext = os.path.splitext(image_filename)[1]
    if ext not in ('.jpg', '.jpeg', '.png', '.gif', '.pdf', '.svg'):
        if '|' in image_filename:  # format [[a.png|500]]
            rets = image_filename.split('|')
            image_filename = rets[0]
            print('image splited by | ')
        else:
            rets = image_filename.split()
            image_filename = rets[0]  # format ![](a.png "some description")
            image_description = ' '.join(rets[1:])
            print('image splited out description: %s.' % image_description)
    orig_image = os.path.join(image_dir, image_filename)
    orig_path = os.path.join(base_path, orig_image)
    #dest_path = os.path.join('assets', image_filename)
    dest_path = image_filename
    #if not os.path.isdir('assets'):
    #    os.mkdir('assets')
    #if image_dir:
    #    new_dir = os.path.join('assets', image_dir)
    #    if not os.path.isdir(new_dir):
    #        os.mkdir(new_dir)
    #print('rename from %s to %s' % (orig_path, dest_path))
    try:
        shutil.move(orig_path, dest_path)
    except:
        print('failed to move %s!!!' % orig_path)
    output = '![](%s)' % dest_path
    if image_description:
        output += '\n' + image_description
    return output


def process(infile):
    outlines = []
    with open(infile, "r") as fp:
        lcnt = 0
        for line in fp:
            lcnt += 1
            if lcnt in (1, 2, 4):  # skip front matter
                continue
            if line.startswith('[['):
                ret = re.sub(pattern_pdf, replace_markdown, line)
            else:
                ret = re.sub(pattern_markdown, replace_markdown, line)
                ret = re.sub(pattern_wikilink, replace_markdown, ret)
            outlines.append(ret)
    output = "".join(outlines)
    with open(infile, "w") as fp:
        fp.write(output)


if __name__ == "__main__":
    infile = sys.argv[1]
    process(infile)

思源插件里有个导入链接的转化工具，可以先尝试用那个转化一下 ob 的链接，如果那个转化完还不行，那只能去 ob 那边找一下如何导出标准化 markdown 的教程，我记得是有的，导出后就可以直接库导入思源。

收到，谢谢。看起来大家提及的主要痛点就是 wiki link，刚好我在 ob 里基本都是标准的 link 形式，所以这个倒是问题不大。

直接用 vscode 打开看能不能识别就知道了，比如图片、链接。另外所谓没能导入是指的什么？
