IntelliSense & Tools

The Gokino editor integrates intelligent tools to help you write code faster and more accurately.

IntelliSense (Intelligent Code Completion)

The editor suggests code based on the current context:

Function suggestions: typing Serial. lists available methods such as begin(), println().
Variable suggestions: typing the first characters of a declared variable suggests its completion.
Code snippets: quick templates for for loops and if/else structures.

Live linter: syntax problems (for example a missing ;) are flagged within moments of typing — a gutter marker plus red squiggles under the offending code.
Compiler diagnostics: after a Verify, GCC errors such as sketch.ino:4:5: error: 'x' was not declared in this scope are mapped back to line 4, column 5 in the editor. Fixing the code and compiling again clears the markers automatically.
Missing library notification: when the sketch includes a library that is not installed (#include <DHT.h>), a banner suggests installing it and takes you to the Library tab with the name pre-filtered.

Format document: Shift + Alt + F re-indents the sketch to standard C/C++ Arduino style (blocks inside {}). String literals, URLs and comments are preserved.
After formatting, the file is saved by auto-save or immediately with Ctrl/Cmd + S.

Located just below the tab bar, it shows the current symbol path (file → function → block).

(1) Search panel. (2) Query and match counter.

A search-and-replace tool is integrated directly into the editor.

Ctrl/Cmd + F opens the find bar with a match counter (e.g., 1 of 3) and Up/Down navigation.
Ctrl/Cmd + H adds the replace field; Replace All applies the change to the whole file and marks it as modified.
The panel closes with the ✕ button at its right edge.
