vi (vim)

A nice introduction on vi can be found here.

Configurations for Python

Greenplanet has already installed vim. You can check the version of vim installed by typing in version in vim’s command mode. The vim is only the basic version and does not have python setting, such as automatic indenting. Users can improve their experience with vim by editing the .vimrc file and .vim folder. If the file and folder do not exist, create them.

1. Download pydiction

   1. download the newest version of pydiction from here.

   2. copy python_pydiction.vim to ~/.vim/after/ftplugin; also copy complete-dict and pydiction.py to ~/.vim.

   3. edit the .vimrc file and put the following codes in it:

      let Tlist_Auto_Hightlight_Tag=1
      let Tlist_Auto_Open=1
      let Tlist_Auto_Update=1
      let Tlist_Display_Tag_Scope=1
      let Tlist_Exit_OnlyWindow=1
      let Tlist_Enable_Dold_Column=1
      let Tlist_File_Fold_Auto_Close=1
      let Tlist_Show_One_File=1
      let Tlist_Use_Right_Window=1
      let Tlist_Use_SingleClick=1
      nnoremap<silent><F8> :TlistToggle<CR>
      
      filetypepluginon
      autocmdFileType python setomnifunc=pythoncomplete#Complete
      autocmdFileType javascrīpt setomnifunc=javascriptcomplete#CompleteJS
      autocmdFileType html setomnifunc=htmlcomplete#CompleteTags
      autocmdFileType css setomnifunc=csscomplete#CompleteCSS
      autocmdFileType xml setomnifunc=xmlcomplete#CompleteTags
      autocmdFileType php setomnifunc=phpcomplete#CompletePHP
      autocmdFileType c setomnifunc=ccomplete#Complete
      
      
      let g:pydiction_location='~/.vim/complete-dict'
      setautoindent
      settabstop=4
      setshiftwidth=4
      setexpandtab
      settextwidth=0
      syntax on
      filetypeindentpluginon
      

Now you can type retab in vim to change tab into spaces.

2. If you want highlight your code, copy the highlight.vim from here to ~/.vim/plugin.
3. You can also download python syntax to make the highlighting better. Copy python.vim from here to ~/.vim/syntax/.

Find and Replace/Add

For example, adding # at beginning of line 14-20:

14,20s/^/#/

git

Powerful tool for verson control and cooperation. A nice introduction can be found here: git-the simple guide (in whatever language you prefer!).

Different ways of doing git add

git add .

Looks at the working tree and adds all those paths to the staged changes if they are either changed or are new and not ignored, it does not stage any ‘rm’ actions.

git add -u

Looks at all the currently tracked files and stages the changes to those files if they are different or if they have been removed. It does not add any new files, it only stages changes to already tracked files.

git add -A

Equivalent to git add .; git add -u.

Delete a branch

Remote:

git push origin --delete <branchName>

Local:

git branch -d local_branch

Overwrite local change

git fetch --all
git reset --hard origin/master

Set global alias

Add and commit in one line. Set global alias for the first time:

git config --global alias.add-commit '!git add -A && git commit'

and then:

git add-commit -m 'Whatever you want to say'

Set global igore files

It’s convenient to make certain system-generated files ignored by git. Create a file called .gitignore, add the type of file you want to ignore, and do:

git config --global core.excludesfile ~/.gitignore

Here’s an example of the .gitignore file.

Transfer repository between different version control system

For example, transfer your repository from Bitbucket to GitHub (Sorry Bitbucket!). First import your repository to GitHub using importer provided by GitHub: https://porter.github.com/new. Then in your local up-to-date repository:

git remote rename origin bitbucket
git remote add origin https://github.com/IAmJustAnExamplePerson/AndIAmJustAnExampleRepository.git
git push origin master

Decompilers

Save you source code from byte-code.

uncompyle2

For Python2.7. Source code at https://github.com/wibiti/uncompyle2. Usage:

uncompyle2 <pyc file>

unpyc3

For Python3.2. Source code at https://code.google.com/p/unpyc3/. Usage (in Python):

from unpyc3 import decompile
import foo
print(decompile(foo))
