How do I prompt for input in a Linux shell script?

Edit 2015-10-29: Adding readline's history capacity Depending on posix compliant: could work on poor system with generic shell environments bash specific: using so called bashisms and if you want simple in line question / answer (generic solutions) pretty formated interfaces, like ncurses or more graphical using libgtk or libqt... use powerful readline history capability (new oct 2015)

• Check if italic font is supported:

$ echo -e "\e[3mitalic\e[23m"

• Also check:

$ infocmp $TERM | grep sitm
 sgr0=\E(B\E[m, sitm=\E[3m, smacs=\E(0, smam=\E[?7h,

A guide to writing a language grammar (TextMate) in Atom

Tree sitter

• Atom is transitioning to an entirely new way of defining grammars using tree-sitter. This will be enabled by default quite soon now. It is theoretically faster and more powerful than regex based grammars (the one described in this guide), but requires a steeper learning curve. My understanding is that regex based grammars will still be supported however (at least until version 2), so this guide can still be useful. To enable it yourself, go to Settings -> Core and check Use Tree Sitter Parsers

Links for tree-sitter help:

• tree-sitter: the main repo
• tree-sitter-cli: converts a JavaScript grammar to the required C/C++ files
• node-tree-sitter: module to use Tree-sitter parsers in NodeJS

Guide to your first Tree-sitter grammar

NOTE: The Tree-sitter API and documentation has changed and improved since this guide was created. I can't guarantee this is up to date.

About

Tree-sitter is the new way Atom is providing language recognition features, such as syntax highlighting, code folding, autocomplete, and more. In contrast to TextMate grammars, which work by regex matching, Tree-sitter will generate an entire syntax tree. But more on that can be found in it's own docs.

Here, we look at making one from scratch.

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.
