From cron_expr struct to const char *

[Lepiqpiq]

Hello,

First of all, I would like to say great job for this lib.
What do you think of creating a function that take a cron_expr structure as a paramater and return a string corresponding to the cron_expr structure that you pass in the function ?
const char * CronExprToString(struct cron_expr * cron);
I think that would be helpfull in certain application.

Thank you,

@Lepiqpiq What is the case? You want to make cron_expr by hand and see the expression that can produce it?
I see two issues:

1. Many cron_expr structures will have many expressions that can produce them.
2. Many cron_expr structures will have no expressions that can produce them.

@exander77 cron_generate_expr does not support option "CRON_DISABLE_YEARS"
Just a forgotten #ifndef CRON_DISABLE_YEARS line 805

[exander77]

@Lepiqpiq You are correct, I pushed a fix.

[exander77]

@Lepiqpiq I have to add tests that run compilation with CRON_DISABLE_YEARS to be sure I don't break it in the future.

[exander77]

@Lepiqpiq Btw, what do you use the library for?

[exander77]

@Lepiqpiq It should be pretty stable, you can see calls in the ccronepr_test.c.
I run all the test expressions through parse, generate, parse and then compare the structure produces. All test cases pass.

@Lepiqpiq I improved this functionality, so it has some support for repeats as well.
