Such packages offer in general a ;; lot of customizable options so probably some of these options change the ;; type or are renamed because the old type and/or name of the option makes no ;; sense in the new release. ;; ;; Especially options which have changed the type of their value are now a ;; problem for the user which want to upgrade to the latest ECB-version: If ;; the user has saved a certain value for option X in its .emacs-file but the ;; type of this saved value doesn't match the new defined type in the ;; defcustom-form after an ECB-upgrade then there can occur serious problems ;; like ECB can not be started anymore or even Emacs can not be started ;; without errors. ;; ;; Until now there was only one way to fix these problems: The user must ;; manually edit his .emacs-file and remove all entries for options which have ;; now another type. After this and after restarting Emacs the new ;; default-values of the type-changed options in the new ECB-release are ;; active and the user can go on using Emacs and ECB. But this approach to fix ;; the incompatible-option-problem has two serious drawbacks: ;; 1. The user must manually edit the customize-section in his .emacs-file. ;; This should normally not be done and if then only by old-handed ;; Emacs-users. ;; 2. The customized value of the option X in the old-release (with the old ;; type) is lost because after removing the related entry from the ;; .emacs-file the new default-value is active, so the user must ;; re-customize the option X. ;; ;; OK, this is one half of the option-upgrade-problem but a new ECB-release ;; can also rename a option from name X to name Y because the new name Y makes ;; much more sense and/or is more mnemonic. If only the name has changed but ;; not the type this is not a serious problem like above but also annoying ;; because the customized value of the old-option X takes no effect in the new ;; release but instead the default-value of the new-option Y is now active. ;; But nevertheless this problem has the drawback number 2 (see above). ;; ;; The last category of upgrade-problems is a renamed option which has also ;; changed its type. ;; ;; ecb-upgrade.el is the solution for all these problems: ;; - It checks all customized values of all ECB-options if they are still ;; type-compatible. If not then it tries to upgrade the old-value to the new ;; value-type and if this is not possible then it resets the option to the ;; new default value and store it via customize in the .emacs-file (or in ;; any file which is used for customized options). ;; - It offers a special constant `ecb-upgradable-option-alist' which allows ;; the ECB-maintainers to define special transformings for renamed options ;; so even the value of an old-option X can be savely transformed to the ;; new-option Y and the old setting is not lost. ;; ;; All these checks and transformings are done at beginning of activating ECB. ;; If ECB has recognized incompatible or renamed options it does its ;; upgrading/reseting-job so all ECB-options have correct types so ECB can ;; start correct. After ECB is started it displays a list of all upgraded or ;; reseted option with their old and new values. ;; ;; How does this library work: ;; ;; The important functions are `ecb-check-not-compatible-options' and ;; `ecb-upgrade-not-compatible-options': ;; ;; The former one checks if all customized values of ECB-options have still ;; correct type. If not the incompatible options and their old values are ;; stored in an alist `ecb-not-compatible-options'. Only this function is ;; allowed to changed this alist!! ;; ;; The latter one processes now this alist and looks for every incompatible ;; option if there is an entry in `ecb-upgradable-option-alist'. If yes then a ;; special value-transforming is tried by `ecb-option-upgrade'. If no or if ;; the special transforming has been failed for any reason then it resets the ;; option to the default-value of current active ECB-version and save it via ;; `customize-save-variable'. ;; ;; So if the ECB-maintainers define no special transforming in the alist ;; `ecb-upgradable-option-alist' for a re-typed option X then all incompatible ;; options are at least reset to their current default-value and therefore ECB ;; can start correct. ;; ;; But there is another function `ecb-upgrade-renamed-options': This function ;; processes the alist `ecb-upgradable-option-alist' and call for every ;; element-key (an old option-symbol) of this alist `ecb-option-upgrade' but ;; only if this element-key is not also contained in the alist ;; `ecb-not-compatible-options' because in this case this option has been ;; already be upgraded/reseted by `ecb-upgrade-not-compatible-options' (see ;; above). ;; ;; So the calling sequence of these three functions must be: ;; 1. `ecb-check-not-compatible-options' ;; 2. `ecb-upgrade-not-compatible-options' ;; `ecb-upgrade-renamed-options' or vice versa. ;; ;; There are also two interactive commands: ;; - `ecb-display-upgraded-options' displays a temp. buffer with all upgraded ;; or reseted ECB-options with their old and new values. ;; - `ecb-upgrade-options': Does all necessary beginning with the ;; incompatibility-check and ending with the display of the options. ;; ;; What must an ECB-maintainer do: ;; ;; + If he wants only a save and correct ECB-start with the new release: ;; NOTHING ;; + If he wants to preserve best possible the customized values of now ;; type-incompatible and/or renamed options: ;; - Adding entries to the alist `ecb-upgradable-option-alist' and ;; - Defining suitable transforming-functions for every of these options. ;; See the comment of `ecb-upgradable-option-alist'. ;; As an addition to this upgrade feature this library offers a set of ;; functions ecb-package-... for downloading and installing newer versions of ;; packages (ecb itself and the required packages)! ;;; History ;; ;; For the ChangeLog of this file see the CVS-repository.
