Configure opening of file paths (semantic history) #

In iTerm’s settings, goto Profiles -> Advanced -> Semantic History.

Opening files in IntelliJ IDEA + Visual Studio Code #

First create IntelliJ IDEA’s command line launcher. Press ⇧ Shift + ⇧ Shift (twice) to bring up the Navigate -> Search Everywhere dialog. Then write “create command-line launcher” in the search box, to select the desired action, then press ⏎ Enter:

Now idea is installed on the command line, on MacOS this is tipically in /usr/local/bin/idea.

Similarly, in Visual Studio Code press ⌘ Cmd + P, type “install code command”, and press ⏎ Enter:

The idea command line utility isn’t compatible with iTerm’s settings, plus if we want to discriminate based on file type, an extra script is needed. Save this in $HOME/bin/iterm-goto:

#!/bin/sh

GOTO_FILE="$1"
GOTO_LINE="$2"
GOTO_CHAR="$3"

if ! [ -f "$GOTO_FILE" ]; then
    echo "ERROR: file path missing or invalid!" >&2
    exit 1
fi

# Discriminate based on file extension, open only .scala or .sbt files in IntelliJ IDEA ...
if [[ "$GOTO_FILE" =~ ^.*\.(scala|sbt)$ ]]; then
    EDITOR_PATH="$(which idea)"

    if [ -z "$IDEA_PATH" ]; then
        EDITOR_PATH="/usr/local/bin/idea"
    fi

    if ! [ -z "$GOTO_LINE" ]; then
        exec "$EDITOR_PATH" --line "$GOTO_LINE" "$GOTO_FILE"
    else
        exec "$EDITOR_PATH" "$GOTO_FILE"
    fi
else
    EDITOR_PATH="$(which code)"

    if [ -z "$EDITOR_PATH" ]; then
        EDITOR_PATH="/usr/local/bin/code"
    fi

    if ! [ -z "$GOTO_CHAR" ]; then
        exec "$EDITOR_PATH" --goto "$GOTO_FILE:$GOTO_LINE:$GOTO_CHAR"
    elif ! [ -z "$GOTO_LINE" ]; then
        exec "$EDITOR_PATH" --goto "$GOTO_FILE:$GOTO_LINE"
    else
        exec "$EDITOR_PATH" "$GOTO_FILE"
    fi
fi

Then in iTerm’s settings, goto Profiles -> Advanced -> Semantic History, and set Run command ... to:

$HOME/bin/iterm-goto \1 \2

Setup automatic dark mode #

NOTE: this is intended for the stable 3.4.x versions, and isn’t needed in the 3.5.x betas.

Create this file in ~/Library/Application\ Support/iTerm2/Scripts/AutoLaunch/auto_dark_mode.py:

#!/usr/bin/env python3.7

import asyncio
import iterm2

async def changeTheme(connection,parts):
    theme_dark = "Dark Background"
    theme_light = "Light Background"
    print(parts)
    
    if "dark" in parts:
        preset = await iterm2.ColorPreset.async_get(connection, theme_dark)
    else:
        preset = await iterm2.ColorPreset.async_get(connection, theme_light)

    # Update the list of all profiles and iterate over them.
    profiles=await iterm2.PartialProfile.async_query(connection)
    for partial in profiles:
        # Fetch the full profile and then set the color preset in it.
        profile = await partial.async_get_full_profile()
        await profile.async_set_color_preset(preset)

async def main(connection):
    app = await iterm2.async_get_app(connection)
    window = app.current_window
    initial_theme = await app.async_get_theme()
    await changeTheme(connection,initial_theme)

    async with iterm2.VariableMonitor(connection, iterm2.VariableScopes.APP, "effectiveTheme", None) as mon:
        while True:
            # Block until theme changes
            theme = await mon.async_get()
            # Themes have space-delimited attributes, one of which will be light or dark.
            parts = theme.split(" ")
    
            await changeTheme(connection,parts)

iterm2.run_forever(main)
