add favor color to a file (`~/.marslo/.colors`)

$ echo "<color-name>" >> ~/.marslo/.colors

[!TIP] download original csscolor.js if necessory:
$ curl -fsSL -O https://raw.githubusercontent.com/jonathaneunice/iterm2-tab-set/master/csscolors.js

$ while read -r i; do

>   hexc=$(for c in $(echo ${rgb} | sed -re 's:,::g'); do printf '%x' $c; done)
>   echo -e """$i :\t$rgb :\t$hexc"""
>   echo "$hexc" >> ~/.marslo/.it2color

usage:
```
$ itit 'title-string-here' [c][b]
```
result:

to change the number of entries in the autocomplete menu:

$ defaults write com.googlecode.iterm2 AutocompleteMaxOptions -int 10

to change the number of coprocess commands remembered:

$ defaults write com.googlecode.iterm2 "Coprocess MRU" -int 10

to preserve whitespace in selections copied to the pasteboard:

$ defaults write com.googlecode.iterm2 TrimWhitespaceOnCopy -bool false

When you open a file from the finder in iTerm2 (e.g., by double-clicking a shell script), it will either open in a window or a tab. By default, it opens in a tab. You can change this with:
```
$ defaults write com.googlecode.iterm2 OpenFileInNewWindows -bool true
```

quite iTerm2 when the last session is closed

$ defaults write com.googlecode.iterm2 MinRunningTime -float 10.0

increase the delay before it attempts to reconfigure itself after a change of monitors
```
$ defaults write com.googlecode.iterm2 UpdateScreenParamsDelay -float 1.0
```

to change the number of paste history entries saved:

defaults write com.googlecode.iterm2 MaxPasteHistoryEntries -int 20

pastes (both regular and slow) are done by splitting the text to paste into chunks. there is a delay between the transmission of each chunk. to change the speed that "paste" pastes at:
```
$ defaults write com.googlecode.iterm2 QuickPasteBytesPerCall -int 1024
$ defaults write com.googlecode.iterm2 QuickPasteDelayBetweenCalls -float 0.01
```

to change the speed that "paste slowly" pastes at:

$ defaults write com.googlecode.iterm2 SlowPasteBytesPerCall -int 16
$ defaults write com.googlecode.iterm2 SlowPasteDelayBetweenCalls -float 0.125

to disable using the pinch gesture to change font size:

$ defaults write com.googlecode.iterm2 PinchToChangeFontSizeDisabled -bool true

to keep LC_CTYPE from being set when locale environment variables are set:
```
$ defaults write com.googlecode.iterm2 DoNotSetCtype -bool true
```

to allow Growl notifications to be posted for the current tab:

$ defaults write com.googlecode.iterm2 GrowlOnForegroundTabs -bool true

to tune smart cursor color settings:

$ defaults write com.googlecode.iterm2.plist SmartCursorColorBgThreshold -float 0.5
$ defaults write com.googlecode.iterm2.plist SmartCursorColorFgThreshold -float 0.75

to allow a three-finger tap to act like a three-finger click:

$ defaults write com.googlecode.iterm2.plist ThreeFingerTapEmulatesThreeFingerClick \
-bool true

to change the set of characters that are considered part of a URL (besides alphanumerics):

$ defaults write com.googlecode.iterm2.plist URLCharacterSet -string \
".?\\/:;%=&_-,+~#@!*'()|[]"

to use some experimental optimizations that will improve performance (safety not guaranteed):
```
$ defaults write com.googlecode.iterm2.plist ExperimentalOptimizationsEnabled -bool true
```

to tweak tab sizes:

$ defaults write com.googlecode.iterm2 UseUnevenTabs -bool false
$ defaults write com.googlecode.iterm2 MinTabWidth -int 75
$ defaults write com.googlecode.iterm2 MinCompactTabWidth -int 60
$ defaults write com.googlecode.iterm2 OptimumTabWidth -int 175

to change your search engine:

$ defaults write com.googlecode.iterm2 SearchCommand \
-string "http://google.com/search?q=%@"

to adjust the speed of the animation of the hotkey window's appearance and disappearance:
```
$ defaults write com.googlecode.iterm2 HotkeyTermAnimationDuration \
-float 0.25
```
to adjust the amount of dimming of split panes. Set the value to a floating-point number between 0 (no dimming) and 1 (complete dimming). The default is 0.15:
```
$ defaults write com.googlecode.iterm2 SplitPaneDimmingAmount \
-float 0.25
```

advanced paste

remove the last newline character when pasting

Welcome to the iTerm2 Python REPL!

This is an interactive Python interpreter where you can experiment with
scripts. Unlike standard Python interpreters, you can use "await" not inside an
async function. Here's an example script to try:

import iterm2
connection=await iterm2.Connection.async_create()
await iterm2.Window.async_create(connection)
