asv-to-usv

Convert ASCII Separated Values (ASV) to Unicode Separated Values (USV). Built with the USV Rust crate.

Syntax:

stdin | asv-to-usv | stdout

Example:

cat example.asv | asv-to-usv

More examples below.

Options

Options for USV separators and modifiers:

• -u, --unit-separator : Set the unit separator (US) string.

• -r, --record-separator : Set the record separator (RS) string.

• -g, --group-separator : Set the group separator (GS) string.

• -f, --file-separator : Set the file separator (FS) string.

• -e, --escape : Set the escape (ESC) string.

• -z, --end-of-transmission : Set the end of transmission (EOT) string.

Options for USV style:

• --style-braces : Set the style to use braces, such as "{US}" for Unit Separator.

• --style-controls : Set the style to use controls, such as "\u001F" for Unit Separator.

• --style-symbols : Set the style to use symbols, such as "␟" for Unit Separator.

Options for USV layout:

• --layout-0: Show each item with no line around it. This is no layout, in other words one long line.

• --layout-1: Show each item with one line around it. This is like single-space lines for long form text.

• --layout-2: Show each item with two lines around it. This is like double-space lines for long form text.

• --layout-units: Show each unit on one line. This can be helpful for line-oriented tools.

• --layout-records: Show each record on one line. This is like a typical spreadsheet sheet export.

• --layout-groups: Show each group on one line. This can be helpful for folio-oriented tools.

• --layout-files: Show one file on one line. This can be helpful for archive-oriented tools.

Options for command line tools:

• -h, --help : Print help

• -V, --version : Print version

• -v, --verbose... : Set the verbosity level: 0=none, 1=error, 2=warn, 3=info, 4=debug, 5=trace. Example: --verbose …

• --test : Print test output for debugging, verifying, tracing, and the like. Example: --test

Install

Install:

cargo install asv-to-usv

Link: https://crates.io/crates/asv-to-usv

Example

Suppose example.asv contains:

a\u001Fb\u001Ec\u001Fd\u001E

Run:

cat example.asv | asv-to-usv

Output:

a␟b␟␞
c␟d␟␞

If you prefer to render no newlines, which is more like the input:

cat example.csv | asv-to-usv --layout-0

Output:

a␟b␟␞c␟d␟␞

If you prefer to render markers with braces, to see the markers more easily:

cat example.csv | asv-to-usv --style-braces

Output:

a{US}b{US}{RS}
c{US}d{US}{RS}

FAQ

What converters are available?

• asv-to-usv & usv-to-asv

• csv-to-usv & usv-to-csv

• json-to-usv & usv-to-json

• xlsx-to-usv & usv-to-xlsx

When to use this command?

Use this command when you want to convert from ASV to USV.

A typical use case is when you have ASV data, such as a collection of units and records, and you want to convert it to USV data, such as for visual editing.

Our real-world use case is converting a bunch of document-oriented data from a variety of programs to a variety of data formats, spreadsheets, and databases.

Why use USV instead of ASV?

See the documentation for USV.

Is USV aiming to become a standard?

Yes, USV is submitted to IETF.org as an Internet-Draft work in progress: link.

Can I build my own USV tools?

Yes, and you may freely use the USV RFC and USV Rust crate.
