Texteditors for Mac OS X
I have recently swtiched main system to Mac OS X (I also use Ubuntu Linux a lot). First things first, I needed to choose texteditor. My criteria on the basic texteditor is quite simple
- Good syntax highlighting for my languages (PHP, SQL, HTML, CSS, Javscript)
- Snippets of some kind (I want it to be easy to reuse code).
- Possibility (but not mandatory) to group files in projects
- Set encoding as UTF-8 and change end of line.
- A nice search and replace
- Line-numbering
I now run Smultron and Eclipse+PDT, they are both free and very good. I also liked skEdit and Textmate among others, but Smultron has so many features and Eclipse+PDT is so good with objectoriented code (but I will probably donate later on) and they are both FREE. But I have to say it was not easy to choose, there were many good options.
Here are some links to editors on Mac, why not try them and give your opinion?
