From a76a744a4562775ade19e9ddff8a50af5c2c6a6e Mon Sep 17 00:00:00 2001 From: Eric Satterwhite Date: Sun, 1 Feb 2026 07:26:15 -0600 Subject: [PATCH 1/8] feat(chrono): port of the node chrono package This is a go port of the chrono package from npm used to allow for nlp style date parsing for the log package. There isn't anything in the go land space that implmemnt anything that resembles the same kind of flexibility and accuracy. Currently this focuses on the english locale --- core/chrono/QUICK_START.md | 71 +++++ core/chrono/README.md | 196 +++++++++++++ core/chrono/chrono.go | 230 +++++++++++++++ core/chrono/chrono_test.go | 325 ++++++++++++++++++++++ core/chrono/common/references.go | 135 +++++++++ core/chrono/en/constants.go | 166 +++++++++++ core/chrono/en/en.go | 96 +++++++ core/chrono/en/en_casual_test.go | 221 +++++++++++++++ core/chrono/en/en_month_test.go | 88 ++++++ core/chrono/en/en_parsers_test.go | 165 +++++++++++ core/chrono/en/en_refiners_test.go | 179 ++++++++++++ core/chrono/en/en_time_test.go | 99 +++++++ core/chrono/en/en_weekday_test.go | 165 +++++++++++ core/chrono/en/parsers/casual.go | 68 +++++ core/chrono/en/parsers/holiday.go | 25 ++ core/chrono/en/parsers/month.go | 72 +++++ core/chrono/en/parsers/relative.go | 164 +++++++++++ core/chrono/en/parsers/relative_test.go | 231 +++++++++++++++ core/chrono/en/parsers/slash.go | 182 ++++++++++++ core/chrono/en/parsers/time.go | 101 +++++++ core/chrono/en/parsers/time_units.go | 251 +++++++++++++++++ core/chrono/en/parsers/time_units_test.go | 286 +++++++++++++++++++ core/chrono/en/parsers/weekday.go | 108 +++++++ core/chrono/en/refiners.go | 267 ++++++++++++++++++ core/chrono/examples/basic/main.go | 68 +++++ core/chrono/results.go | 286 +++++++++++++++++++ core/chrono/types.go | 158 +++++++++++ core/mod.go | 1 + 28 files changed, 4404 insertions(+) create mode 100644 core/chrono/QUICK_START.md create mode 100644 core/chrono/README.md create mode 100644 core/chrono/chrono.go create mode 100644 core/chrono/chrono_test.go create mode 100644 core/chrono/common/references.go create mode 100644 core/chrono/en/constants.go create mode 100644 core/chrono/en/en.go create mode 100644 core/chrono/en/en_casual_test.go create mode 100644 core/chrono/en/en_month_test.go create mode 100644 core/chrono/en/en_parsers_test.go create mode 100644 core/chrono/en/en_refiners_test.go create mode 100644 core/chrono/en/en_time_test.go create mode 100644 core/chrono/en/en_weekday_test.go create mode 100644 core/chrono/en/parsers/casual.go create mode 100644 core/chrono/en/parsers/holiday.go create mode 100644 core/chrono/en/parsers/month.go create mode 100644 core/chrono/en/parsers/relative.go create mode 100644 core/chrono/en/parsers/relative_test.go create mode 100644 core/chrono/en/parsers/slash.go create mode 100644 core/chrono/en/parsers/time.go create mode 100644 core/chrono/en/parsers/time_units.go create mode 100644 core/chrono/en/parsers/time_units_test.go create mode 100644 core/chrono/en/parsers/weekday.go create mode 100644 core/chrono/en/refiners.go create mode 100644 core/chrono/examples/basic/main.go create mode 100644 core/chrono/results.go create mode 100644 core/chrono/types.go create mode 100644 core/mod.go diff --git a/core/chrono/QUICK_START.md b/core/chrono/QUICK_START.md new file mode 100644 index 0000000..7e29e27 --- /dev/null +++ b/core/chrono/QUICK_START.md @@ -0,0 +1,71 @@ +# Quick Start Guide + +## Installation + +```bash +# Clone or copy the chrono-go directory to your project +cd /path/to/your/project +``` + +## Basic Usage + +```go +package main + +import ( + "fmt" + "time" + + "chrono/en" +) + +func main() { + // Parse a single date (returns first match) + date := en.ParseDate("An appointment on Sep 12", time.Now(), nil) + if date != nil { + fmt.Println(date.Format("2006-01-02")) + } + + // Parse all dates in text + results := en.Parse("Sep 12-13", time.Now(), nil) + for _, result := range results { + fmt.Printf("Found: %s\n", result.Text) + fmt.Printf("Date: %s\n", result.Start.Date()) + } +} +``` + +## Running Tests + +```bash +cd chrono-go +go test -v ./... +``` + +## Running Example + +```bash +cd chrono-go +go run examples/basic/main.go +``` + +## Supported Formats + +- **Casual**: today, tomorrow, yesterday, tonight +- **Weekdays**: Monday, next Friday, last Tuesday +- **Months**: September 12, Jan 1st, Dec 2024 +- **Times**: 3pm, 14:30, at 9am + +## Module Structure + +``` +Module: chrono +Import: "chrono/en" +``` + +## Documentation + +- `README.md` -
