From 4ae53d93fb7665e46b4bdb86359805baa1bc18e6 Mon Sep 17 00:00:00 2001 From: Darren Schroeder <343840+fdncred@users.noreply.github.com> Date: Wed, 20 Sep 2023 12:57:58 -0500 Subject: [PATCH] new command: `into value` (#10427) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # Description This new command `into value` is a command that tries to infer the type of data you have in a table. It converts each cell to a string and then runs a set of regular expressions on that string. This was mostly cobbled together after looking at how polars does similar things. The regular expressions were taken straight form polars and tweaked. ### Before ```nushell ❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] | update col1 {|r| $r.col1 | into int } | update col3 {|r| $r.col3 | into float } | update col4 {|r| $r.col4 | into bool } | update col5 {|r| $r.col5 | into datetime } | update col6 {|r| $r.col6 | into datetime } ╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮ │0│ 1│two │3.40│true│a month ago│8 hours ago│ ╰─┴────┴────┴────┴────┴───────────┴───────────╯ ``` or ```nushell ❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] | into int col1 | into float col3 | into bool col4 | into datetime col5 col6 ╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮ │0│ 1│two │3.40│true│a month ago│8 hours ago│ ╰─┴────┴────┴────┴────┴───────────┴───────────╯ ``` ### After ```nushell ❯ [[col1 col2 col3 col4 col5 col6]; ["1" "two" "3.4" "true" "2023-08-10 14:07:17.922050800 -05:00" "2023-09-19"]] | into value ╭#┬col1┬col2┬col3┬col4┬───col5────┬───col6────╮ │0│ 1│two │3.40│true│a month ago│8 hours ago│ ╰─┴────┴────┴────┴────┴───────────┴───────────╯ ``` It's definitely not perfect. There are ways it will fail because on regular expressions not working on all formats. My hope is that people will pick this up and add more regular expressions and if there are problems with the existing ones, change them. This is meant as a "starter command" with easy entry for newcomers that are looking to chip in and help out. Also, some tests probably need to be added to ensure what we have now doesn't break with updates. # User-Facing Changes # Tests + Formatting # After Submitting --- Cargo.lock | 24 +- crates/nu-command/Cargo.toml | 2 +- crates/nu-command/src/conversions/into/mod.rs | 2 + .../nu-command/src/conversions/into/value.rs | 474 ++++++++++++++++++ crates/nu-command/src/default_context.rs | 1 + 5 files changed, 490 insertions(+), 13 deletions(-) create mode 100644 crates/nu-command/src/conversions/into/value.rs diff --git a/Cargo.lock b/Cargo.lock index 2e27590110..65b79999cd 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -480,7 +480,7 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "6798148dccfbff0fae41c7574d2fa8f1ef3492fba0face179de5d8d447d67b05" dependencies = [ "memchr", - "regex-automata 0.3.0", + "regex-automata 0.3.8", "serde", ] @@ -2397,9 +2397,9 @@ dependencies = [ [[package]] name = "memchr" -version = "2.5.0" +version = "2.6.3" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "2dffe52ecf27772e601905b7522cb4ef790d2cc203488bbd0e2fe85fcb74566d" +checksum = "8f232d6ef707e1956a43342693d2a31e72989554d58299d7a88738cc95b0d35c" [[package]] name = "memmap2" @@ -4313,14 +4313,14 @@ dependencies = [ [[package]] name = "regex" -version = "1.9.0" +version = "1.9.5" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "89089e897c013b3deb627116ae56a6955a72b8bed395c9526af31c9fe528b484" +checksum = "697061221ea1b4a94a624f67d0ae2bfe4e22b8a17b6a192afb11046542cc8c47" dependencies = [ "aho-corasick", "memchr", - "regex-automata 0.3.0", - "regex-syntax 0.7.3", + "regex-automata 0.3.8", + "regex-syntax 0.7.5", ] [[package]] @@ -4331,13 +4331,13 @@ checksum = "6c230d73fb8d8c1b9c0b3135c5142a8acee3a0558fb8db5cf1cb65f8d7862132" [[package]] name = "regex-automata" -version = "0.3.0" +version = "0.3.8" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "fa250384981ea14565685dea16a9ccc4d1c541a13f82b9c168572264d1df8c56" +checksum = "c2f401f4955220693b56f8ec66ee9c78abffd8d1c4f23dc41a23839eb88f0795" dependencies = [ "aho-corasick", "memchr", - "regex-syntax 0.7.3", + "regex-syntax 0.7.5", ] [[package]] @@ -4348,9 +4348,9 @@ checksum = "f162c6dd7b008981e4d40210aca20b4bd0f9b60ca9271061b07f78537722f2e1" [[package]] name = "regex-syntax" -version = "0.7.3" +version = "0.7.5" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "2ab07dc67230e4a4718e70fd5c20055a4334b121f1f9db8fe63ef39ce9b8c846" +checksum = "dbb5fb1acd8a1a18b3dd5be62d25485eb770e05afb408a9627d14d451bae12da" [[package]] name = "relative-path" diff --git a/crates/nu-command/Cargo.toml b/crates/nu-command/Cargo.toml index 06f7038011..8d4b8f8a49 100644 --- a/crates/nu-command/Cargo.toml +++ b/crates/nu-command/Cargo.toml @@ -71,7 +71,7 @@ print-positions = "0.6" quick-xml = "0.30" rand = "0.8" rayon = "1.7" -regex = "1.7" +regex = "1.9.5" roxmltree = "0.18" rusqlite = { version = "0.29", features = ["bundled"], optional = true } same-file = "1.0" diff --git a/crates/nu-command/src/conversions/into/mod.rs b/crates/nu-command/src/conversions/into/mod.rs index 9f0f27962a..f56a56167d 100644 --- a/crates/nu-command/src/conversions/into/mod.rs +++ b/crates/nu-command/src/conversions/into/mod.rs @@ -9,6 +9,7 @@ mod float;
