升级安装Hexo

下载源码

Hexo和我使用的主题都一直在升级,我的版本还是比较老,存在很多兼容性问题。使用一些自动化部署到互联网也会遇到一些问题,今天干脆把Hexo及我使用的Hexo Next主题都升级到较新的版本。

这里做一下记录,以便以后在升级当中会方便一些。

升级到Hexo 5.4.1。

我使用的是Source Tree,直接切换到 tag 5.4.1,如果是克隆,可以直接指定tag 5.4.1。

git clone git@github.com:hexojs/hexo.git new-blog -b 5.4.1

安装

1
$ npm install hexo-cli -g

INFO Install dependencies
INFO Start blogging with Hexo!

$ cd new-blog

启动Blog

1
$ hexo s

安装Hexo Next主题

安装Hexo Next主题的v8.10.0版本。

1
git clone git@github.com:next-theme/hexo-theme-next.git themes/next -b v8.10.0

主题部分要改动的东西太多了,放弃了。以后有时间的时候再弄吧。

通过 Jupyter Notebook 做数据研究不错,但版本控制是个问题。后来找到一个最佳实践。

在保存ipynb文件之前,自动做一个ipynb转到py文件的转换,然后只把py文件提交到github上面。

生成jupyter notebook配置文件

1
jupyter notebook --generate-config

运行后会生成 ~/.jupyter/ipython_notebook_config.py 文件

编辑配置文件

添如下内容:

### If you want to auto-save .html and .py versions of your notebook:
# modified from: https://github.com/ipython/ipython/issues/8009
# Solution2: https://jupyter-notebook.readthedocs.io/en/stable/extending/savehooks.html
import os
from subprocess import check_call
import re

def clear_prompt(dir_path, nb_fname, log_func):
"""remove the number in '# In[ ]:'"""
name, ext = os.path.splitext(nb_fname)
pattern = re.compile(r'^# In\[\d+\]:')

for n_ext in ['.py', '.txt']:
script_name = os.path.join(dir_path, name+n_ext)
if os.path.exists(script_name):
new_lines = []
with open(script_name, 'rt', encoding='utf-8') as f:
lines = f.readlines()
for line in lines:
new_line = re.sub(pattern, '# In[ ]:', line)
new_lines.append(new_line)
with open(script_name, 'wt', encoding='utf-8') as f:
f.writelines(new_lines)
log_func('Remove number in "# In[ ]:"! File Name: %s' % script_name)
break

def post_save(model, os_path, contents_manager):
"""post-save hook for converting notebooks to .py scripts"""
if model['type'] != 'notebook':
return # only do this for notebooks
d, fname = os.path.split(os_path)
check_call(['jupyter', 'nbconvert', '--to', 'script', fname], cwd=d) # '--no-prompt',
log = contents_manager.log
# log.info('Filename:%s'%fname)
clear_prompt(d, fname, log.info)
# check_call(['ipython', 'nbconvert', '--to', 'html', fname], cwd=d)

c.FileContentsManager.post_save_hook = post_save

重启jupyter notebook,配置生效。
当保存ipynb文件时,会自动生成py文件。

配置github的.gitignore文件

1
*.ipynb

设置以后,可能会发现规则没有生效。在项目根目录,执行如下命令:

1
git rm -r --cached .

安装PyUserInput前,需要安装如下依赖:

Linux - Xlib
Mac - Quartz, AppKit
Windows - pywin32, pyHook

1
pip install pywin32

https://www.lfd.uci.edu/~gohlke/pythonlibs/

安装pyHook,找到python对应的版本,比如:pyHook‑1.5.1‑cp37‑cp37m‑win_amd64.whl

下载到本地,安装

1
pip install pyHook‑1.5.1‑cp37‑cp37m‑win_amd64.whl

安装PyUserInput

1
pip install PyUserInput

x_dim, y_dim = m.screen_size()
m.click(x_dim/2, y_dim/2, 1)
k.type_string('Hello, World!')


# pressing a key
k.press_key('H')
# which you then follow with a release of the key
k.release_key('H')
# or you can 'tap' a key which does both
k.tap_key('e')
# note that that tap_key does support a way of repeating keystrokes with a interval time between each
k.tap_key('l',n=2,interval=5)
# and you can send a string if needed too
k.type_string('o World!')


#Create an Alt+Tab combo
k.press_key(k.alt_key)
k.tap_key(k.tab_key)
k.release_key(k.alt_key)

k.tap_key(k.function_keys[5]) # Tap F5
k.tap_key(k.numpad_keys['Home']) # Tap 'Home' on the numpad
k.tap_key(k.numpad_keys[5], n=3) # Tap 5 on the numpad, thrice


# Mac example
k.press_keys(['Command','shift','3'])
# Windows example
k.press_keys([k.windows_l_key,'d'])


# Windows
k.tap_key(k.alt_key)
# Mac
k.tap_key('Alternate')
