# UNIC Command-Line Tools
[](https://crates.io/crates/unic-cli)
This package provides comman-line tools for developers, helping with common
Unicode tasks, like generating, transforming, and inspecting strings.
## How to Install
Install the `unic-cli` package using [Cargo](https://doc.rust-lang.org/stable/cargo/).
```bash
$ cargo install unic-cli
```
## How to Use It
### Echo Command
The `unic-echo` command generates Unicode strings, similar to the common `echo`
command.
```bash
# Normally, the output ends with a newline
$ unic-echo Hello سلام
Hello سلام
# Get the codepoints or UTF-8/UTF-16, instead of plain text
$ unic-echo Hello سلام -o codepoints
U+0048 U+0065 U+006C U+006C U+006F U+0020 U+0633 U+0644 U+0627 U+0645
# Or see how to escape as a Rust string literal
$ unic-echo Hello سلام -o rust-escape
"Hello \u{633}\u{644}\u{627}\u{645}"
# Also the input can be in codepoints, or UTF-8/UTF-16 hex
$ unic-echo -i codepoints U+0 U+20 U+41 U+A0 -o rust-escape
"\u{0} A\u{a0}"
$ unic-echo --help
Write arguments to the standard output
USAGE:

-n, --no-newline No trailing newline
-V, --version Prints version information
OPTIONS:
-i, --input <FORMAT> Specify input format (see list below)
-o, --output <FORMAT> Specify output format (see list below)
ARGS:
<STRINGS>... Input strings (expected valid Unicode)
INPUT FORMATS:
plain Plain Unicode characters (default)
codepoints Unicode codepoints (hex)
utf8-hex UTF-8 bytes (hex)
utf16-hex UTF-16 words (hex)
OUTPUT FORMATS:
plain Plain Unicode characters (default)
codepoints Unicode codepoints (hex)
utf8-hex UTF-8 bytes (hex)
utf16-hex UTF-16 words (hex)
braces-escape String literal with \u{...} escapes for
| js6-escape control and non-ASCII characters
| rust-escape
braces-escape-all String literal with \u{...} escapes for
| js6-escape-all all characters
| rust-escape-all
braces-escape-control String literal with \u{...} escapes for
| js6-escape-control control characters
| rust-escape-control
```
### Inspector Command
The `unic-inspector` command lists the Unicode characters in the input string,
along with their properties.
```bash
$ unic-inspector Hello سلام
l | U+006C | LATIN SMALL LETTER L | Lowercase_Letter
l | U+006C | LATIN SMALL LETTER L | Lowercase_Letter
o | U+006F | LATIN SMALL LETTER O | Lowercase_Letter
| U+0020 | SPACE | Space_Separator
س | U+0633 | ARABIC LETTER SEEN | Other_Letter
ل | U+0644 | ARABIC LETTER LAM | Other_Letter
ا | U+0627 | ARABIC LETTER ALEF | Other_Letter
م | U+0645 | ARABIC LETTER MEEM | Other_Letter
```
Soon, this tool will allow selecting which properties to show, as well as
support grouping characters by Grapheme Clusters, Words, Sentenses, etc.
