TeXlipse

TeXlipse plug-in: ~~http://texlipse.sourceforge.net/ (this is also the address of the update site)~~ (obsolete since 2.x)

Seems to be in active development again since v2.x, but there are bugs to be ironed out.

Word wrap fix (TeXlipse 1.5.0 contains a broken version of Ahtik word wrap):
Alternative 1: http://dev.cdhq.de/eclipse/word-wrap/ Adds a "Toggle Word Wrap" menu, I had problems with the key binding
Alternative 2: http://ahtik.com/blog/projects/eclipse-word-wrap/ Install newer version that works correctly. You still have to edit the plugin.xml of texlipse as described in Alternative 1 to avoid deactivation of wrapping.
(I just had a fight with this feature. Word wrapping worked, but once I changed to a different tab on the editor and back, it reverted to no word wrapping. After editing the plugin.xml file as descibe in Alternative 1, word wrapping only worked for a moment and changed back instantly. In the end, using both alternatives at the same time solved it. -- szarnyasg)
Line numbering is also buggy, installing the fix from "Alternative 1" above works with both alternatives

Project explorer displays project names with a P/ prefix when JDT is not installed (probably), this is bug in the label provider of TeXlipse, I could not find any workaround (apart from installing JDT).

Download a dictionary for your language (simple text file, one word per line, dict file extension).
You should create a folder called dict near TeXlipse and copy the file there
For example, WinEdt has a lot of these (http://www.winedt.org/Dict/)
Don't forget to convert them to UTF-8!
In Texlipse, go to the Windows/Preferences/Texlipse/SpellChecker page
Set the path for the folder where you saved the file (dict)
Enable Built-in spell checker
In the Windows/Preferences/General/Editors/Text Editors/Spelling page
Enable spell checking
Select Latex as spelling engine
Restart TeXlipse, it should now underline errors
You can use quick fixes (Ctrl+1) to correct them or add words to your user dictionary
You can select the language of your project in the Project properties\LaTeX Builder Settings, by setting the language code.

With forward search, while browsing the .tex source of a large document, you can at any position instruct the PDF viewer to either open the PDF file, or scroll the already opened file directly to the given location.
With inverse search, you can double-click a piece of text in SumatraPDF, and TeXcipse will directly jump to the corresponding .tex line.
