# Description fixed #11678 The sub-commands of from command (`from {csv, tsv, ssv}`) name columns starting from index 0. This behaviour is inconsistent with other commands such as `detect columns`. This PR makes the subcommands index 0-based. # User-Facing Changes The subcommands (`from {csv, tsv, ssv}`) return a table with the columns starting at index 0 if no header data is passed. ``` ~/Development/nushell> "foo bar baz" | from ssv -n -m 1 ╭───┬─────────┬─────────┬─────────╮ │ # │ column0 │ column1 │ column2 │ ├───┼─────────┼─────────┼─────────┤ │ 0 │ foo │ bar │ baz │ ╰───┴─────────┴─────────┴─────────╯ ~/Development/nushell> "foo,bar,baz" | from csv -n ╭───┬─────────┬─────────┬─────────╮ │ # │ column0 │ column1 │ column2 │ ├───┼─────────┼─────────┼─────────┤ │ 0 │ foo │ bar │ baz │ ╰───┴─────────┴─────────┴─────────╯ ~/Development/nushell> "foo\tbar\tbaz" | from tsv -n ╭───┬─────────┬─────────┬─────────╮ │ # │ column0 │ column1 │ column2 │ ├───┼─────────┼─────────┼─────────┤ │ 0 │ foo │ bar │ baz │ ╰───┴─────────┴─────────┴─────────╯ ``` # Tests + Formatting When I ran tests, `commands::touch::change_file_mtime_to_reference` failed with the following error. The error also occurs in the master branch, so it's probably unrelated to these changes. (maybe a problem with my dev environment) ``` $ toolkit check pr ~~~~~~~~ failures: ---- commands::touch::change_file_mtime_to_reference stdout ---- === stderr thread 'commands::touch::change_file_mtime_to_reference' panicked at crates/nu-command/tests/commands/touch.rs:298:9: assertion `left == right` failed left: SystemTime { tv_sec: 1719149697, tv_nsec: 57576929 } right: SystemTime { tv_sec: 1719149697, tv_nsec: 78219489 } failures: commands::touch::change_file_mtime_to_reference test result: FAILED. 1533 passed; 1 failed; 32 ignored; 0 measured; 0 filtered out; finished in 10.87s error: test failed, to rerun pass `-p nu-command --test main` - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🔴 `toolkit test` - ⚫ `toolkit test stdlib` ``` # After Submitting nothing
