Score Comparison Plot:

The following plot shows how this terminal’s scores compare to all other terminals tested.

../_images/iterm2_scores_scaled.png

Scaled scores comparison across all metrics (normalized 0-100%)

Final Scaled Score Calculation:

  • Raw Final Score: 83.51% (weighted average: WIDE + NARROW + ZWJ + LANG + VS16 + 0.33 * SRI + 0.33 * SFZ + RI + CAP + 0.5 * GFX + 0.5 * RSC) the categorized ‘average’ absolute support level of this terminal.

    Note

    RSC (Resources) is a composite CPU, memory, and runtime score. RSC is weighted at 0.5 (half as powerful as other metrics). FEAT (Features) is the fraction of notable features supported. GFX (Graphics) scores 100% for modern protocols (iTerm2, Kitty), 50% for legacy only (Sixel, ReGIS), 0% for none.

  • Final Scaled Score: 81.2% (normalized across all terminals tested). Final Scaled scores are normalized (0-100%) relative to all terminals tested

The XTGETTCAP sequence (DCS + q Pt ST) allows applications to query terminfo capabilities directly from the terminal emulator, rather than relying on the system terminfo database.

Text Sizing Protocol (OSC 66)

iTerm2 does not support the Text Sizing protocol.

Truecolor Support

iTerm2 supports 24-bit truecolor, detectable via:

  • XTGETTCAP (RGB capability): yes (RGB)

  • DECRQSS (truecolor probe): no

  • COLORTERM: yes (truecolor)

OSC 52 Clipboard Support

iTerm2 supports OSC 52 clipboard operations (detected via DA1 extension 52 + XTGETTCAP Ms).

  • DA1 extension 52: yes

  • XTGETTCAP Ms: yes

Terminal Identification

iTerm2 is identified as iTerm2 version 3.6.10 (detected via XTVERSION).

  • XTVERSION (raw): iTerm2 3.6.11

  • XTVERSION: yes

  • XTGETTCAP TN: yes (xterm-256color)

  • ENQ: no

  • TERM_PROGRAM: yes (iTerm.app)

  • TERM: no (xterm-256color)

Reproduction

To reproduce these results for iTerm2, install and run ucs-detect with the following commands:

uvx ucs-detect --rerun data/iterm2.yaml

Test Performance

Performance data for iTerm2 is not available.
