Configuration on PS1 files in Vim

Thank you Lixar for my first ever Co-op placement. Although there are many colleagues like me, love to use Linux/Unix as our main OS, work must be done as what we are expected. Because they choose Azure cloud initially, I have to do development work under Windows.

It doesn’t bother me too much, I still have my Linux as a guest VM on the second screen for transition. Now I need to study some PowerShell scripting.

Vim doesn’t support ps1 files for highlighting. So there is a plugin for that. (Check out its github page for installation)

I have linebreaks set up, I honour “80 chars per line” rule. I don’t think the nature of PowerShell honours that, at least not our internal scripts. Still I want to keep linebreaks in my vimrc, but to skip linebreaks for any ps1 files. A little bit of research and documentation lookup, add a line to my vimrc:

autocmd BufRead,BufNewFile *.ps1    set nolbr

It works perfectly.

Changing text encoding with Vim

A lot of subtitles in Chinese language are encoded with GB2312 or sometimes Code Page 936 (CP936, aka gbk), are generated under Windows. This brings problems in many Linux based multimedia players.

Converting using iconv is not that hard, since its command is simple to use:

iconv -f gb2312 -t utf8 subtitle.srt -o converted.srt

But in many cases, you will find error as such:

iconv: illegal input sequence at position xxxx.

To solve this, you can need to change the gb2312 to some larger encoding set with the same catagory. For example, gbk is a super set of gb2312.

If you only know the file’s encoding but don’t know its super charset, you can always use vim to convert it.

vim subtitle.srt

Edit it with ++enc option:

:e ++enc=gb2312

Save it with ++enc option:

:w ++enc=utf8 converted.srt

All done!

Vim configuration

This is my VIM configuration, I’d like to make a note here and remember what I did if I ever encounter a system re-install.

See those install notes for installation.

This is the default template of my vimrc, I did have a few modifications, mostly these are related to plugins.
