make utf-8 default for Cygwin 1.7, rewrite init code determining default coding systems -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-02-06 Ben Wing <ben@xemacs.org> * code-init.el: * code-init.el (set-eol-detection): * code-init.el (coding-system-current-system-configuration): * code-init.el (coding-system-default-configuration-table): New. * code-init.el (no-mule-no-eol-detection): * code-init.el (define-coding-system-default-configuration): New. * code-init.el (coding-system-variable-default-value-table): Removed. * code-init.el (no-mule-eol-detection): * code-init.el (coding-system-default-configuration-list): Removed. * code-init.el (coding-system-default-variable-list): * code-init.el (get-coding-system-variable): * code-init.el (set-coding-system-variable): * code-init.el (coding-system-variable-default-value): * code-init.el (reset-coding-categories-to-default): Significant clean-up, add Cygwin-UTF-8 support. 1. Shorten the names of the coding system variables to follow what used to be considered the "abbreviations": default-process-coding-system-read -> process-read default-process-coding-system-write -> process-write buffer-file-coding-system-for-read -> bfcs-for-read default-buffer-file-coding-system -> default-bfcs no-conversion-coding-system-mapping -> no-conv-cs 2. Instead of listing all the defaults in a big, strangely organized table, use a new function `define-coding-system-default-configuration' to define a particular configuration. This uses a hash table stored in `coding-system-default-configuration-table'. Rewrite `coding-system-variable-default-value' appropriately. 3. Rename configurations to eliminate `unix' from the name: unix-no-mule-no-eol-detection -> no-mule-no-eol-detection unix-no-mule-eol-detection -> no-mule-eol-detection unix-mule -> mule This is because these are really for all systems but Windows, not just Unix. 4. Add configuration `cygwin-utf-8', enabled when (featurep 'cygwin-use-utf-8). Uses `utf-8' for all defaults except for `bfcs-for-read', which is `undecided'.
