Homebrew developer gogy has created a very handy application for the PSP. It's called LuaStation. With this application you can develop in LUA right on the PSP!
One thing about LuaStation is that it requires LuaPlayer in order for it to run. It is suggested to read the readme file before installing this.
This release is actually an update. Here are the changes:
- Complete color customization of the GUI.
- Colored code syntax.
- Display line numbers, or a scroll bar.
- Auto-complete for common functions in text entry.
- Auto-help, displays function descriptions and data types.
- Features for text manipulation (select multiple lines, copy, paste, etc)
- Features for navigation (Top, bottom, PgUp, PgDown, Home, End, goto line)
- Test scripts from within the editor.
- Edit scripts in Hex.
- Customizable key shortcuts for editor controls.
- RAM management.
