Add a method to transform epoch time to a human readable format

2023-04-05T13:17:11+00:00

* dump/utils.scm: Import srfi-19. Export time-unix->string. (time-unix->string): New function. Signed-off-by: Munyoki Kilyungi

Move string-blank? to (dump utils).

2022-10-30T15:15:32+00:00

* dump.scm (string-blank?): Move to ... * dump/utils.scm (string-blank?): ... here.

Rename the delete verb of map-alist to remove.

2022-03-10T09:18:14+00:00

The delete verb of map-alist somehow interacts with the delete function from (srfi srfi-1), and I'm not able to figure out how. It is simpler to just rename the delete verb to remove. * dump/utils.scm: Do not rename the delete function from (srfi srfi-1). (map-alist): Rename the delete verb to remove. * tests.scm ("map-alist docstring example"): Update test.

Specify map-alist behaviour for multiple set verbs.

2021-12-16T10:13:04+00:00

* dump/utils.scm (map-alist): Specify behaviour for multiple set verbs.

Generalize collect-keys and key->assoc-ref.

2021-12-16T10:10:02+00:00

The generalized versions---collect forms and translate-forms---will be required by other macros. * dump/utils.scm (collect-forms, translate forms): New public functions. (collect-keys): Rewrite in terms of collect-forms. (key->assoc-ref): Rewrite in terms of translate-forms.

Rename away delete from (srfi srfi-1).

2021-12-16T10:08:21+00:00

delete from (srfi srfi-1) somehow interferes with the delete verb of map-alist. It is not clear why. * dump/utils.scm (dump): Rename delete to srfi:delete while importing.

Implement the map-alist DSL.

2021-12-04T08:54:08+00:00

map-alist is a DSL to transform one association list into another. These transformations are frequently required when dumping tables, especially metadata tables. * dump/utils.scm: New file.
