I've only used it for half an hour so far, but some of it's features have impressed me - the fact that it warns you of variables which have not been declared as private is neat, and the colour coding has made editing easier (particularly with the init.sqf file in F2).Description:
Squint is an editor and static-analyser (error-checker) for ArmA2 and Operation ArrowHead script files.
Features:
- It can work with .sqf, .sqm, .cpp and .ext files
- It can perform syntax colouring of your scripts as you work
- It can analyse your scripts for errors and warn you of them as you work
- It can suggest fixes for common mistakes
- It can work on files inside pbo'd missions or addons
- It can 'expand' included files and macros to help debug preprocessor-related problems
