Article contents:== awful-postgresql [[toc:]] === Description Postgresql support for [[/eggref/5/awful|awful]]. This extension provides the {{enable-db}} and {{switch-to-postgresql-database}} procedures which add Postgresql support for awful, based on the features provided by the [[/eggref/5/postgresql|postgresql egg]]. === Author [[/users/mario-domenech-goulart|Mario Domenech Goulart]] === Repository [[https://github.com/mario-goulart/awful-postgresql|https://github.com/mario-goulart/awful-postgresql]] === Requirements * [[/eggref/5/awful|awful]] * [[/eggref/5/postgresql|postgresql]] === Procedures ==== {{enable-db}} <procedure>(enable-db)</procedure> Enable Postgresql support for [[/eggref/5/awful|awful]]. This procedure basically sets up awful to use the connection, disconnection, query and query escaping procedures for Postgresql databases. ==== {{switch-to-postgresql-database}} <procedure>(switch-to-postgresql-database)</procedure> Resets all the awful db-related parameters to postgresql values (for when using multiple databases under the same awful server). === Parameters ==== {{db-result-processor}} This parameter yields a one-argument procedure (the argument is the object representing the results as returned by the postgresql bindings). The default value is: <enscript highlight=scheme> (lambda (result) (row-map identity result)) </enscript> This parameter has been added in version 0.5. === License Copyright (c) 2008-2018, Mario Domenech Goulart All rights reserved.

'''Warning''': this change may break your code! In case of an empty result set from a query, {{(db-inquirer)}} will now return {{'()}} instead of {{#f}}. This change can be specially harmful in case you have something like <enscript highlight=scheme> (or ($db "some query") "something") </enscript> In this example, if the query returns an empty result set, that expression would produce: * in older awful-postgresql versions: {{"something"}} * in awful-postgresql versions with this change: {{'()}} ===== version 0.5.1 * Fix application of {{db-result-processor}} (patch by Hugo Arregui) ===== version 0.5 * Added {{db-result-processor}} parameter (patch by Hugo Arregui) * Deprecated {{sql-quoter}} parameter ===== version 0.4 * Added {{switch-to-postgresql-database}} procedure ===== version 0.3 * {{db-inquirer}} supports the {{values}} keyword parameter (patch by Stephen Eilert) ===== version 0.2 * fix for {{sql-quoter}} (reflects on awful's {{sql-quote}}) ===== version 0.1 * Initial release Description of your changes:
