Dentang mengambil tajuk yang tidak diinginkan saat menggunakan pelengkapan otomatis dari berbagai IDE


2

Masalah ini dapat dilihat ketika kita berurusan dengan fitur pelengkapan otomatis dari IDE yang diberikan. Saya perhatikan perilaku ini di editor teks seperti: Xcode, Vim, VScode, Atom.

Plugin Penyelesaian Otomatis menggunakan dentang untuk mengambil kembali simbol dari header yang disertakan. Tetapi masalahnya adalah itu menyarankan saya fungsi C dari header saya tidak pernah termasuk.

Seperti yang Anda lihat, saya bahkan tidak menyertakan header tunggal. Tapi ketika saya sertakan misalnya iostream masih memberi saya banyak fungsi C dari libs seperti waktu.h

Saya tidak tahu mengapa dentang menyediakan banyak fungsi lain dari C libs ketika tidak diminta.

Saya menginstal alat baris perintah Xcode saja. OS: High Sierra 10.13.4 (17E199)

Jika kita melihat dependensi main.cpp kita dapat melihat ini:
