Cron expression parser\n\n**Given a cron expression, you can get the previous timestamp or the next timestamp that satisfies the cron expression.**\n\nI have used cron expression syntax to implement a new feature called *deploy freeze window* in Gitploy.\n\n## Install\n\n```shell\ngo get github.com/gitploy-io/cronexpr\n```\n\n## Usage\n\nImport the package, first:\n\n```go\nimport \"time\"\nimport \"github.com/gitploy-io/cronexpr\"\n```\n\n```go\nprevTime := cronexpr.MustParse(\"0 0 29 * *\").Prev(time.Now())\nnextTime := cronexpr.MustParse(\"0 0 29 * *\").Next(time.Now())\n```\n\nYou can check the detail in the `_example` directory.\n\n\n## Implementation\n\n\n```\nField name     Mandatory?   Allowed values    Allowed special characters\n----------     ----------   --------------    --------------------------\nMinutes        Yes          0-59              * / , -\nHours          Yes          0-23              * / , -\nDay of month   Yes          1-31              * / , - \nMonth          Yes          1-12 or JAN-DEC   * / , -\nDay of week    Yes          0-6 or SUN-SAT    * / , - \n```\n\n### Asterisk ( * )\nThe asterisk indicates that the cron expression matches for all values of the field. E.g., using an asterisk in the 4th field (month) indicates every month. \n\n### Slash ( / )\nSlashes describe increments of ranges. For example `3-59/15` in the minute field indicate the third minute of the hour and every 15 minutes thereafter (i.e. `3`, `18`, `33`, and `48`). The form `*/...` is equivalent to the form \"first-last/...\", that is, an increment over the largest possible range of the field.\n\n### Comma ( , )\nCommas are used to separate items of a list. For example, using `MON,WED,FRI` in the 5th field (day of week) means Mondays, Wednesdays and Fridays.\n\n### Hyphen ( - )\nHyphens define ranges. For example, 0-6 indicates every hours between 0 and 6 AM, inclusive.\n\n## Details\n\n* The return value of `Next` and `Prev` is zero if the pattern doesn't match in five years.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgitploy-io%2Fcronexpr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgitploy-io%2Fcronexpr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgitploy-io%2Fcronexpr/lists"}
