Emacs Ada mode version 6.1.0 Ada mode provides auto-casing, fontification, navigation, and indentation for Ada source code files. Cross-reference information output by the compiler is used to provide powerful code navigation (jump to definition, find all uses, etc). By default, only the AdaCore GNAT compiler is supported; other compilers can be supported. Ada mode uses gpr_query to query compiler-generated cross reference information. gpr_query is provided as Ada source code that must be compiled and installed; see ada-mode.info section Installation for instructions. Ada mode will be automatically loaded when you open a file with a matching extension (default *.ads, *.adb). Ada mode uses project files to define large (multi-directory) projects, and to define casing exceptions. Ada mode uses a parser to provide fontification, navigation, and indentation. There are two parsers provided: - elisp, which can be slow on large files, and does not recover from syntax errors. - process, which is implemented in Ada, is fast enough for reasonably large files, supports partial parse for very large files (see wisi-partial-parse-threshold), and recovers from almost all syntax errors. The 'process' parser must be compiled; see ada-mode.info section "process parser". See ada-mode.info for help on using and customizing Ada mode, and notes for Ada mode developers.

Please send wisi bug reports to email@example.com, with 'ada-mode' in the subject. If possible, use M-x report-emacs-bug. * Ada mode 6.1.0 21 Mar 2019 ** Add support for partial parsing; useful in very large files. Files larger than wisi-partial-parse-threshold (default 100_001) will be parsed partially. In general, partial parsing may yield incorrect results for indentation; the Ada menu entry "Edit | Indent lines in file" will parse the entire file and indent correctly. ** Better error correction in the Ada process parser; insert minimimal tokens to complete a statement/declaration before or after the error point. ** New indent option: 'ada-indent-after-trailing-comment' If t (the default), align comment lines imediately following a comment on the same line as code with the preceding comment. Otherwise, ignore the preceding comment. ** Delete support for the GPS backend; no need, given partial parsing and error correction. ** Miscellaneous bug fixes. * Ada mode 6.0.1 8 Dec 2018 ** Compress ada_lr1_parse_table.txt ** Assign copyright in Ada files to FSF * Ada mode 6.0.0 17 Nov 2018 ** Use wisi 2.0; indentation computed directly in parser actions. This has a few user visible changes in indention, making it more consistent. It also makes it faster, so larger files are handled more smoothly. ** Support wisitoken generated Ada code parser, with error correction. The parser runs in a background process. ** ada-fix-compiler-error can now fix errors reported by the background process parser. ** ada-format-paramlist repairs syntax errors in buffer text before scanning. ** Display marks in fringe at location of errors detected by background parser. ** Colorization of type and package names is somewhat improved, but requires full name resolution to get fully correct. ** new user option: ada-end-name-optional, default nil. If non-nil, names at ends of blocks/subprograms are optional (as in standard Ada). Setting this nil matches standard AdaCore style, and significantly improves error correction in the parser (it can use name matching to locate errors). ** new user setting: ada-process-parse-exec, ada-process-parse-exec-opts, gpr-process-parse-exec, gpr-process-parse-exec-opts: the executable and options to run the external parser for Ada and gpr modes. Default to the executables built by the build.sh script included in the ELPA package, empty options. A useful setting for -exec-opts is '("--recover-log" "<log file name>"); this will log every error recovery to a file, so you can examine how well it is working. ** new user setting: ada-parser; must be one of 'elisp, 'process. Defaults to 'process if the executable named by ada-process-parse-exec is found, 'elisp otherwise. ** new user setting: ada-fallback; must be one of nil, 'simple or 'gps. Identifies fallback indentation algorithm used when parser fails; 'simple is "indent to previous line", 'gps is "use the gps indent engine". nil means set to 'gps if the executable named by ada-gps-indent-exec is found. ** new user command: ada-refresh-prj-file. Useful when the project file has been edited. ** Implement an xref backend for Ada, using gpr-query. See (info "(emacs) Xref"). ** The various "find other file" commands assume the use of the Gnu ELPA package other-frame-window; they no longer provide "other window" options. ** ada-xref-refresh (bound to "menu | Ada | Misc | refresh cross reference cache", C-c C-q) now takes a prefix arg to delete the xref files first as well. Useful when compiler options or version have changed. * Ada mode 5.3.1 3 Oct 2017 ** Ada mode 5.2.2 should have been numbered 5.3.0, since it introduced the GPS indentation backend major feature. ** GNAT GPL 2017 is supported for gpr_query and ada_mode_gps_indent; see ada_mode.info for installation instructions. ** New Ada-mode submenu "Select Project" lists all loaded Ada-mode project, making it easier to switch between them. ** New Ada-mode menu entry "Delete project..." allows deleting a loaded project, to reduce clutter in the new "Select Project" menu. ** `ada-add-log-for-current-function' (for a revision control commit) will return a type name. However, `ada-which-function' will not. ** New option `ada-fill-comment-adaptive', if non-nil, causes all comments to be filled to the same width, rather than to the same column. This looks better in deeply nested code. ** When 'ada-auto-case' is nil, 'ada-case-adjust-at-point' used to do nothing; it now capitalizes the word at point. This helps with some alternate casing styles. ** Improve handling of GPR_PROJECT_PATH in 'compilation-environment' when selecting/deselection ada-mode project files. ** ada-gnat-xref-all (used by ada-show-references) now preserves point when appending more references. ** Minor bug fixes. * Ada mode 5.2.2 9 Jul 2017 ** GNAT GPL 2017 is _not_ supported for gpr_query; GNAT GPL 2016 is supported. ** New option ada-indent-hanging-rel-exp; if non-nil, indent hanging lines relative to start of expression. Otherwise, indent relative to previous line. Default nil. ** xref-ada allows entering an identifier to search for without completion. The search is only in the current file. ** ada-show-references, ada-show-local-references now take an 'append' argument, set by interactive prefix; if non-nil, preserve previous output in references buffer. ** Support GPS indentation engine, either as primary or backup. See user guide for how to set it up; it requires compiling Ada code. ** ada_mode_gps_indent patch level 001 fixes ada-gps bugs 2, 6. See test/ada-gps for bug descriptions/tests. ** ada-identifier-at-point properly handles adjacent operator and identifier (ie +Tree). ** When a 'use type' clause is inserted by the compile error correction code, 'use all type' is inserted if the lanuage version is 2012 (the default). ** The context menu is simplified. ** The 'obj_dir' project variable is supported. ** ada-next-statement-keyword, ada-prev-statement-keyword are deleted; use forward-sexp instead. ** The license inserted by ada-skel-modified-gpl uses GPL version 3 language. ** Several indentation bugs are fixed. ** New option ada-gnat-debug-run controls echoing GNAT commands in GNAT buffers. * Ada mode 5.2.1 31 Oct 2016 ** A line starting with '(' is now always indented with ada-indent-broken. Previously, in some cases it was indented by ada-indent - 1. Since the defaults set ada-indent = 3, ada-indent-broken = 2, this is transparent unless you use other values. ** GPR_PROJECT_PATH is set in the compilation process environment when the Ada project is selected, and cleared when the project is deselected. This allows selecting other Emacs projects, then returning to an Ada project. ** New function ada-show-local-references (bound to C-c C-l) searches for references within the current file only. ** New option ada-xref-full-path (default nil) if t, shows full paths in cross references. ** The indentation functions are significantly rewritten to make them better organized and easier to understand and maintain. This resulted in some minor indentation changes, mostly for consistency; in particular, case expressions are indented by ada-indent-broken, to match if espressions. * Ada mode 5.2.0 26 Jul 2016 ** GNAT 2016 drops support for 'gnat find'; users must use gpr_query. ** ada-xref-tool now defaults to gpr_query if gpr_query executable is found in PATH. ** source code for compiling gpr_query is installed with the Gnu ELPA package; instructions for compiling and installing it are in ada-mode.info. ** better handling of cross-compile targets. ** Allow trailing label in a sequence_of_statements: loop ... goto Next; <<Next>> end loop; ** Handle package aspects. ** tested with GNAT GPL 2016. ** several bug fixes * Ada mode 5.1.9 20 Jan 2016 ** New option ada-indent-comment-gnat matches the GNAT style check for comments in all cases (previously, there were some cases where the comment indent algorithm did not match the GNAT check). ** New menu command "Show source file search path"; displays compilation-search-path in a buffer. ** Adding missing grammar statements to allow removing parens around conditional and quantified expressions. ** Key binding for ada-case-create-partial-exception in ada-mode changed to C-c C-M-y; this is easier to type, and matches the key binding in gpr-mode. ** ada-case-keyword changed to accept the symbols 'lower-case, 'upper-case instead of the functions downcase-word, upcase-word. ** ada-case-identifier changed to accept the symbols 'mixed-case, 'lower-case, 'upper-case instead of the functions 'ada-mixed-case, 'ada-lower-case, 'ada-upper-case. ** ada-fix-add-context-clause now sorts "limited with" and "private with" clauses after other clauses. ** ada-align now aligns '=>' in case expressions. ** ada-align-paramlist now handles access function parameters: procedure Choose (X, Y, Z : Integer; Preference : access function (A, B : Integer) return Boolean); ** ada-next-statement-keyword now moves to matching close paren if on open paren, ada-prev-statement-keyword moves from close paren to open paren. ** New hook ada-prj-parse-hook, run from ada-parse-prj-file. ** GPR mode now does case adjust similar to Ada mode. ** gpr parser handles nested case statements without blowing up. ** gpr parser handles package renames ** fix other bugs * Ada mode 5.1.8 10 Apr 2015 ** requires OpenToken 6.0 ** ada-align handle identifiers that start with Ada keywords ** functions for ada-case-identifier now take three args: start, end, force-case ** parsing is not required by find-other-file if the current buffer is larger than wisi-size-threshold ** fix misc bugs * Ada mode 5.1.7 18 Nov 2014 ** add ada-find-file that prompts for a file from the current project, with completion. ** fix bug that prevented Y : Boolean := Boolean'(if True then False); ** add ada-create-select-default-prj, to simplify working with small projects ** Handle deleting whitespace between words, inserting whitespace in the middle of a word properly. ** Change ada-case-adjust to capitalize words in comments and strings by default; C-u adjusts case as if code. ** allow 'raise' in expressions for GNAT GPL 2014 aspects ** move all except keyword face highighting to grammar; much more accurate, easier to maintain, simpler, faster. ** delete gnatinspect support; gpr_query is better ** misc bug fixes * Ada mode 5.1.6 28 Sep 2014 ** improve syntax highlighting of names after 'of', 'new', 'renames' ** fix ada-format-paramlist to handle 'aliased' keyword (new in Ada 2012), and 'not null' without 'access'. ** fix ada-find-other-file in separate bodies; now navigates to the spec. ** restore ada-indent-newline-indent for [return] * Ada mode 5.1.5 12 Jul 2014 ** add C-c <, C-c >; goto-declaration-start, -end ** improve parsing speed significantly * Ada mode 5.1.4 26 May 2014 ** support expression functions ** beginning-of-defun-function, end-of-defun-function are now set. A "defun" is a generic, package, protected, subprogram, or task spec or body. ** C-c C-s is now bound to ada-goto-previous-pos, which goes to the first position in ada-goto-pos-ring. Most navigation functions set ada-goto-pos-ring. This allows easy navigation back to the start of a cross-reference chain. ** xref tool error handlers no longer show the xref tool buffer; the new Ada menu item 'show xref tool buffer' can be used instead. ** The parser supports more deeply nested case statements. * Ada mode 5.1.3 19 Apr 2014 ** more GNAT error message auto-fixes ** support aspects on subprogram declarations; format same as SPARK examples. ** fix bug in ada-syntax-propertize that caused query-replace to screw up ** inhibit reparse due to case adjust; case adjust entire buffer is now _much_ faster. ** Non-ASCII characters supported in Ada mode buffers, including GNAT bracket notation. * Ada mode 5.1.2 16 Mar 2014 ** fix another packaging bug; forgot to add files to ELPA git! * Ada mode 5.1.1 14 Mar 2014 ** require wisi-1.0.2, to fix packaging bug ** gnat-find now called with -a to include read-only .ali files in the results. * Ada mode 5.1.0 13 Mar 2014 ** Emacs 24.2 supported, via cl-lib in Gnu ELPA ** Better handling of aspects. ** 'record' is aligned with 'type' in derived types ** Several minor indentation bugs have been fixed. ** Added "2.2 Upgrading from previous versions" to the user guide. ** ada-align now properly handles subprograms with the opening paren on the same line as the preceding code and code on the same line as the closing paren: function Foo (Param_1 : Integer; Param_2 : Integer) return Integer; ** When no project file is selected, the default variables are consistently used instead. Previously, the default variables were only used when parsing a project file. ** info files are properly visible in main info menu ** 'C-c ;' used to run `comment-dim', which is bound to 'M-;' in the global keymap. 'C-c ;' now gives an error with a message saying 'use M-; instead'. * Ada mode 5.0.1 Feb 2 2014 First public release, via ELPA * Ada mode 5.0.0 Dec 24 2013 ** first release in ELPA ** Previous version was 4.00, in Emacs core. 5.0.1 is a complete rewrite, using a generalized LALR parser that caches syntactic information in text properties.
