Declt 2.0.1 "Benjamin Sisko" is out

Declt 2.0.1 "Benjamin Sisko" is out. This is a bugfix release with one internal change (a special variable was not following the earmuffs convention) and one actual bugfix (the same Texinfo anchor was generated for symbols with the same name but in different packages).

I've just released version 2.0 of ASDF-FLV, my ASDF extension for supporting file-local variables (ala *PACKAGE*). The code hasn't changed, but as for my other libraries, the system and package names are now prefixed with net.didierverna. ASDF-FLV is also available on GitHub now.

The reason I'm doing this now is that at least two of my other libraries are going to use it in a mandatory way, either directly or indirectly (and in turn, that's because no implementation has bothered to implement CDR #9 yet ;-).

Declt 2.0 is out -- IMPORTANT

Declt 2.0 "Kathryn Janeway" is out. This release doesn't contain any change in functionality, yet deserves a major version upgrade since it contains 3 important changes: an infrastructure revamp (along the lines of what Clon endured not so long ago), a license switch from the GNU GPL to a BSD one, and finally a system / package name change. The prefix is now net.didierverna instead of com.dvlsoft. Do I need to apologize for this again? :-)

Declt 1.1 is released


as promised last week, I've just released a new version of Declt, my reference manual generator for ASDF systems. This new version (1.1) is now able to document Clon again (the documentation of which has been updated on the website).

New in this release:

  • Declt now properly handles and documents complex system and component dependencies, such as :feature :require and :version statements,
  • Declt also documents a system's :if-feature if any.

But the most important addition is the ability to document several ASDF systems in the same reference manual. More precisely, Declt now documents not only the main system but also all its subsystems. A subsystem is defined as a system on which the main one depends on in any way, and which is also part of the same distribution (under the same directory tree). Declt also understands multiple system definitions from the same .asd file.

Clon 1.0b24 is released -- IMPORTANT


I'm happy to announce the release of the next beta version of Clon, the Common Lisp / Command Line Options Nuker library. This release doesn't contain much change in terms of functionality, but it contains a lot of change in terms of infrastructure, plus very important and backward-incompatible modifications. So if you're a Clon user, please read on.

First of all, a huge revamp of the library's infrastructure (package hierarchy, ASDF and Make implementations) occurred. A large portion of this work is actually not mine, but Fare's (big thanks to him, 'cause the level of ASDF expertise required just means that I couldn't have done that by myself). The purpose here was twofold: first, remove all logic from the ASDF files (so that other system managers could be used; not sure that's actually useful right now) and second, split the library in two: the core, basic functionality and the non-standard platform-dependent bells and whistles (read: termio support). The result is that Clon now comes with 4 different ASDF systems! A setup system allows you to configure some stuff prior to loading the library, a core system allows you to load only the basic functionality and the regular one loads everything, autodetecting platform-dependent features as before. The fourth system is auxiliary and not to be used by hand. All of this is properly documented. For a code maniac like me, this new infrastructure is much more satisfactory, and I've learned a lot about ASDF less known features.

Next, I've moved the repository to Github. Please update your links! It seems that I've lost all my former tags in the process, but oh well...Only the Git repo has moved. The main Clon web page still contains the full history of tarballs, the preformatted documentation, and will continue to do so in the future.

Finally (I've kept this to myself until the last possible minute because I'm scared like hell to tell): I've changed the systems and packages names... The com.dvlsoft prefix has been replaced with net.didierverna. All other libraries of mine will eventually endure the same surgery. It's for the best, I apologize for it and I swear I will never ever do that again, EVER (fingers crossed behind my back).

So what's next? Before considering an official 1.0 release, there are two things that I want to do. First, cleanup some remaining Fixmes and some shaky error handling. Second, provide an even simpler way of using Clon than what the Quick Start chapter in the doc demonstrates. The idea is to just implement a main function with keyword arguments, and those argument magically become command-line options.

A side-effect of this work is that Declt now chokes on Clon, because some ASDF features that it doesn't understand are in use. So Declt has a couple of new challenges ahead, and you should expect a new release in the weeks to come.

Declt 1.0 is out

After 15 betas, I'm happy enough with the current state of Declt to finally make a 1.0 release.

A lot of things have changed since the previous version, sometimes in a backward-incompatible way. Many more items are documented (including, as you have recently seen, method combinations). In addition to the reference manual, generated by Declt itself, there is now a real user manual.

Declt is still SBCL-only, requires ASDF 3 and Texinfo 4 but generates code that is compatible with Texinfo 5. Also, beware, I've deleted the old repository and moved the project to GitHub. Below is a more precise description of what Declt currently does.

Declt (pronounce "dec'let") is a reference manual generator for Common Lisp libraries. It works by loading an ASDF system and introspecting its contents. The generated documentation contains the description for the system itself and its components (modules and files), the packages defined in that system and the definitions found in those packages.

Exported and internal definitions are listed separately. This allows the reader to have a quick view on the library's public API. Within each section, definitions are sorted lexicographically.

In addition to ASDF system components and packages, Declt documents the following definitions: constants, special variables, symbol macros, macros, setf expanders, compiler macros, functions (including setf ones), generic functions and methods (including setf ones), method combinations, conditions, structures, classes and types.

The generated documentation includes every possible bit of information that introspecting can provide: documentation strings, lambda lists (including qualifiers and specializers where appropriate), slots (including type, allocation and initialization arguments), definition source file etc.

Every documented item provides a full set of cross-references to related items: ASDF component dependencies, parents and children, classes direct methods, super and subclasses, slot readers and writers, setf expanders access and update functions etc.

Finally, Declt produces exhaustive and multiple-entry indexes for every documented item.

Reference manuals are generated in Texinfo format (compatible, but not requiring Texinfo 5). From there it is possible to produce readable / printable output in info, HTML, PDF, DVI and PostScript with tools such as makeinfo, texi2dvi or texi2pdf.

The Declt reference manual is the primary example of documentation generated by Declt itself.

el-rcfiles is released (first public version)

I've been using this for years, but never bothered to make it public until now.

el-rcfiles is a very small and simple library which provides Unix-like RC files for Emacs Lisp libraries. It's compatible with GNU Emacs and XEmacs, available in ELPA form, as a tarball and from GitHub. More details (including download) available here, but here is also the library's commentary section, for quick reference.

;;; Commentary:

;; The purpose of el-rcfiles is to provide the equivalent of traditional
;; Unix rc files (i.e. configuration files) for Emacs Lisp
;; libraries. The advantages of using configuration files are the
;; following:
;;   - your initialization file is less bloated,
;;   - since configuration files are lazily loaded, your Emacs session
;;     is (or begins) lighter. That is unless you already use lots of
;;     EVAL-AFTER-LOAD forms...

;; Usage:

;; 1. Load the library, go to the rcfiles Custom group and tweak (or not).
;; 2. Put a call to (rcfiles-register-rc-files) in your initialization
;;    file. This function can also be called interactively anytime you
;;    add, remove or modify a configuration file.
;; 3. Put your configuration code for a library `foo' in a file called
;;    `<rcfiles-directory>/foo<rcfiles-pseudo-extension>.el'.

FiXme 4.2 is out

I'm pleased to announce that, after more than two years, I've managed to put up a very small release of FiXme (my collaborative annotations tool for LaTeX2e) in which I didn't even author the two included changes...

Keep the faith. FiXme is still alive !

New in this veresion (4.2):

** Improve Danish translation
thanks to Lars Madsen.
** Fix buglet in redefinition of \@wrindex
reported by Norman Gray.

Declt 1.0b15 "Kyoto" is out

This is Declt 1.0b15, the "Kyoto" release... Declt is a reference manual generator for Common Lisp libraries.

This version underwent a major internals overhaul, required by some of the new features described below:

  • Packages sections now advertise all definitions instead of just the symbols naming them. They also advertise their use-list and used-by-list, with cross-references.
  • Conditions, structures and classes now advertise their sub- and super-classes, direct methods, initargs and slots, with cross-references.
  • Slots documentation include docstring, type, initargs, initforms, readers and writers with cross-references.
  • Declt now documents symbol macros and compiler macros.
  • The *LINK-FILES* special is gone (M-x all-hail-purely-functional-style).
  • All ASDF components now advertise their descriptions and long descriptions, if any.
  • Docstrings are displayed in a more reader-friendly fashion.
  • Documentation entries for methods are nested within the corresponding generic function entry.

Grab it at the usual place.

Clon 1.0b23 is out

A new version of Clon, the Command-Line Options Nuker is out.

Amongst other things, the following improvements have been made:

  • Support for ABCL has been updated, now that it provides a full MOP.
  • A workaround for SBCL's CC environment variable problem has been implemented. If the variable is not set (required for sb-grovel), Clon now switches to restricted mode instead of aborting.
  • The DUMP macro has been extend to accept a &rest argument that will be passed on to the underlying, implementation-specific, dumping facility.
  • A contrib directory has been added, for storing unapplied patches, suggestions etc.

Declt 1.0b14 is out

I've just released a new version of Declt, my reference manual generator for ASDF systems.

This release containts some improvements based on Sabra Crolleton's feedback. The most notable improvements are support for two new license types (MIT and LGPL), a new :DECLT-NOTICE keyword argument that gives you control on the "automatically generated by Declt" notice that appears in the reference manuals, and a bug fix (missing support for empty lists in lambda-lists).

Declt 1.0b13 is out

I've just released a new version of Declt, my reference manual generator for ASDF systems. This release includes some uninteresting internals update, plus an important bug fix: there were two calls to FIND-METHOD missing an ERRORP flag set to nil, leading to Declt throwing an error where it shouldn't have.

Grab it at the usual place.

Clon 1.0b22 is out

A new version of Clon, the Command-Line Options Nuker is out.

The most important change in this release is the support for LispWorks, which brings the number of supported implementations to 8. One left to go, and I may eventually switch to RC status. Thanks to Martin Simmons for providing a fully functionnal version of LW 6.1. As for CLISP and Allegro, there is an optional dependency on CFFI for LispWorks.

Two backward incompatible changes that may affect you:

  • Variables renamings: *current-context* has been renamed *context*, and *default-synopsis* has been renamed *synopsis*. This should remain transparent unless you're using Clon in a somewhat advanced way.
  • clon:exit has been upgraded to SBCL's new quitting protocol. If you use this function (or if you want to compile the demo programs), please upgrade to SBCL 1.0.57.

Finally, support for terminal autodetection and stream handling in general has been improved for all implementations.

Grab it at the usual place.

Clon 1.0b21 is out

One year between b19 and b20. 4 days between b20 and b21...

This new version of Clon introduces support for a new compiler, Allegro Common Lisp, in both standard and modern form. Support for dumping is only rudimentary for ACL (although it's only a marginal feature of the library). The dump macro uses Allegro's dumplisp mechanism to dump a lisp image which is not directly executable (full application delivery is complicated and only available in the Enterprise edition). Apart from that, the rest should work fine. As in the case of CLISP, Allegro may benefit from the presence of CFFI in order to provide terminal autodetection. This is an optional dependency only.

Grab it at the usual place.

Clon 1.0b20 is out

I'm happy to announce a new release of Clon, the Command-Line Options Nuker for standalone Common Lisp executables. In addition to a lot of uninteresting code and infrastructure changes, this new release comes with several important improvements and new features.

At the end-user level

  • there is a new error handler available via the --clon-error-handler option, called "interactive". This error handler provides the same restarts as the one called "none" (which actually triggers the Lisp debugger), but in a less frightening way for end-users not knowing about Lisp at all. In particular, the error and restart messages are more readable and you don't see a Lisp stack anywhere. See the end-user manual and the user manual for more information.
  • there is a new option called --clon-lisp-information which, as its name suggests, provides information about the underlying Lisp (implementation type and version). This will in fact be more useful for developers than for end-users, but it's still and end-user level feature. See the end-user manual for not much more information.

At the user-level

  • Clon now provides a command-line polling API through the functions cmdline-options-p and cmdline-p. See the user manual for more information.
  • Support for using Clon interactively, that is, without dumping executables has been improved. This is mostly useful for debugging purposes. See the user manual for more information.
  • Clon now provides a compile-time / run-time unified configuration facility thanks to a variable named cl-user::com.dvlsoft.clon.configuration that is handled before the ASDF system is loaded. Thanks to this, Clon is now able to communicate its own indentation information to (X)Emacs directly (thanks to a process that I've previously described here), and also handles portability problems in a smoother way (see below).
  • One of the available configuration options is called :restricted mode. In this mode, Clon never attempts to communicate with ttys via ioctl calls, at the expense of terminal autodetection (size and highlighting). This is implemented by making a termio ASDF module conditionally loaded in the system definition. There are cases where Clon will switch to restricted mode automatically (e.g. when using CLISP compiled without FFI support). However, some other situations are more problematic, for instance when using SBCL under MinGW, in which case the SB-GROVEL module is available but doesn't work. In such situations, it is necessary to configure Clon explicitely for restricted mode before loading the system. See the user manual for more information.

That's it. Grab it at the usual place. Yesterday, I realized that it's been slightly more than a year since the b19 release. Gee, time flies like the wind...

Patcher 4.0 is released

I'm happy to announce the release of Patcher version 4.0. This is a major release introducing many new features and enhancements.

Patcher is a tool designed to automate and ease the maintenance of archive-based projects. It provides assistance in building, reporting and committing patches, as well as in handling the corresponding ChangeLog entries, for example by creating skeletons. Patcher is the official tool for XEmacs development.


  • Support floating projects and temporary relocation allowing to use the same project descriptor for various directories.
  • Support for automatic detection of submodules via the :submodule-detection-function project option and the patcher-detect-submodules function. Currently supported RCS submodules are Mercurial and Git via the functions 'patcher-hg-detect-submodules.
  • Support ephemeral ChangeLogs thanks to a new :change-logs-status project option. Ephemeral ChangeLogs are not stored in ChangeLog files, but exist only temporarily for mail or log message insertion (See ChangeLogs Status in the documentation).
  • ChangeLog minor mode providing easy navigation through the mail/ChangeLog buffers cycle via C-c C-p n, C-c C-p p, C-c C-p N, C-c C-p P and C-c C-p m (See ChangeLogs Navigation in the documentation).
  • Support for switching to mail buffer and inserting ChangeLogs at once via C-c C-p l from ChangeLog buffers.
  • patcher-mail-insert-change-logs gets a prefix argument allowing to temporarily change the ChangeLogs appearance. It also supports inserting ChangeLogs even when the project is set not to.
  • Additional binding for patcher-logmsg-commit: C-c C-p c
  • Commit command buffer is now editable Commit is done via C-c C-p c or C-c C-c (patcher-cmtcmd-commit).
  • Fontification of commit command and log message buffers with comment syntax and initial informative help. See new Patcher faces.
  • Support for commit or log message canceling via C-c C-z.
  • Support for project abortion via C-c C-p k or C-c C-k in all relevant buffers, including ChangeLogs.
  • Support Subject: header modification in mail adaptation routines via a new project option :subject-rewrite-format.
  • Support project-wide dynamic subject modification via C-c C-p S in both mail and log message buffers.
  • Implement :kill-source-files-after-sending project option
  • Support for source file saving
  • Support for CVS diff's broken exit code policy via a new project option: :ignore-diff-status.


  • Improved support for temporary subprojects making them behave like permanent ones (with a specific subdirectory and set of files).
  • Much better error handling including exit code checking for external processes.
  • Improved support for overlapping Patcher instances through buffer and file referencing for both ChangeLog and source files.
  • Documentation rewrite and sections organization cleanup
  • More checks for project consistency including missing or spurious ChangeLog entries, source diffs, undiffable and uncommittable projects etc.
  • Improved project rediffing including support for partially generated ChangeLog skeletons, and interactive prompting for skeleton un/re-generation.


  • Mercurial themes renamed from 'mercurial to 'hg in order to remain consistent with the other RCS theme names.
  • ChangeLogs insertion in mail buffers rebound to C-c C-p l
  • Compressed ChangeLogs insertion in logmsg buffers rebound to C-c C-p L
  • Removed directory-sep-char hacks until the need for it raises again. Probably better implemented via project options anyway.
  • Diff commands can no longer be changed from patcher-mail-adapt but instead, the prefix argument allows for temporary subproject specification.
  • patcher-*-subproject entry points removed since they are no longer needed (see above).
  • Removed :kill-source-file-after-diffing option
  • :kill-source-files-after-sending renamed to :kill-sources-after-sending
  • patcher-mail-check-change-logs-insertion is now a project option named :check-change-logs-insertion.
  • patcher-mail-check-commit-action is now a project option named :check-commit.
  • :change-logs-diff-command option now understands nil instead of 'diff
  • The 'packed ChangeLogs appearance has been renamed to 'pack
