    carnet: update the help about --search.
    
    This amounts for the change in behavior where multiple arguments
    become collated with wildcards ".*" instead of the initial or "|", the
    latter making actually little sense.  This make the overall usage of
    the --search function more ergonomic.

    carnet: catenate search words with wildcards.
    
    The initial search pattern that combined the words passed in multiple
    arguments to the --search option using pipes "|" to "or" them was of
    little use.  The behavior using a wildcard ".*" results in much more
    intuitive output results.

    carnet: better warn about missing register.txt.
    
    This change gets rid of the five seconds delay, which speeds up the
    run time of the test suite, and prints the warning after the editor
    handed back the control of the terminal, if a warning is necessary.

    carnet: introduce the ability to have a motd.
    
    This change introduces the motd.txt associated to a carnet, to print
    out a message of the day.  This file is completely optional but can be
    used for storing one's general mood, or orientation in life, or lovely
    ascii art, whatever.
    
    On a personnal note, this follows up on the feeling that I learned
    something very important from using carnet, and I wished a mechanism
    to keep it in mind at all time.

    carnet: fix search for todo items.
    
    Integrated search patterns needed to be decompensated for the fix
    brought to '\n'.  The duplication of '\' also caused some breakages
    that could not be decompensated and prevented the task management
    system to not capture open tasks correctly.  Therefore, the correction
    is removed and the old behavior for '\' is restored.

    makefile: provide a release target with CHANGES.
    
    The "release" makefile target allows build an archive that will
    contain a CHANGES file autogenerated out of the git log.  Because it
    is obtained from the git log, committing this file is going to be
    inconvenient and won't be part of the git tree.  Therefore, the two
    levels of cleanup targets: "clean" and "purge" are redifined in order
    to separate them between cleanup of a tarball release and cleanup of
    the git tree.  As a rule of thumb, running `make clean` from the
    tarball is intended to restore it in its original state, while running
    `make purge` may destroy files from the tarball than can't be
    reconstructed anymore, but is intended for restoring the git tree in
    its original state.
    
    This is a good opportunity to begin the introduction of some sanity
    checks when proceeding to a release, like making sure that the last
    commit is about the version bump, and making sure that the version
    bump is aligned to the actual carnet version stored in the script.

    if I hadn't been strict about honoring EDITOR and the like.

    carnet: improve the search pattern sanitization.
    
    Until then, searches involving backslashes or carriage returns did not
    work very well, unless end users doubled the quantity of backslashes
    by hand.  This adjustment better handles handling backslashes in
    general, and the sanitization of the carriage return, which needs
    special handling since the initial backslash of the \n gets translated
    into a real carriage return before the sanitization has a chance to
    kick in.

    carnet: use tab aligned help.
    
    While this is not particularly good practice, in this particular case,
    this helps with default line rewrap behavior, that introduces tabs
    when eight consecutive spaces are used for alignment.  I'm hopeful to
    find a better alignment method that accomodates better with help2man.

    Revert "carnet: allow arguments without dashes."
    
    This reverts commit a190718399956c6b92d768eb3fa18fcc51d59614.
    
    After some testing done without dash arguments, I am not convinced
    that specifying options without dashes is of much added value.  I also
    notice that this makes online help heavier and the automated manual
    page more ugly.  Undoing this change also allows me to keep increasing
    the patchlevel of carnet instead of introducing a new minor version,
    not that matters much but I prefer adding real functionalities to bump
    the minor version.

    carnet: fix overtime offset.
    
    When introducing the ability to capture risks of overtime, it happened
    that the legacy configuration recording only hours improperly also
    recognised the number as a number of minute, i.e. a CARNET_OVERTIME=9
    was computed as an overtime of 09:09 duration instead of 09:00.
    
    This change restores the proper behavior while still preserving the
    ability to set HH:MM overtime detection durations.

    what this is about.

Date:   Sun Aug 24 00:36:17 2025 +0200

    carnet: allow arguments without dashes.
    
    This change adds the functionality of running carnet specific options
    without the initial "--", for instance to search a pattern, one can
    now run:
    
            $ carnet search pattern
    
    or to list todo items:
    
            $ carnet todo
    
    Such changes closes the door to an eventual way to pass an arbitrary
    character string to do something else; for instance it could have been
    purposed for giving an arbitrary trailing context.  If this proved to
    be an error, the change may be undone in carnet v2.

    carnet: provide sudo user in trailing context.
    
    This is useful on a shared carnet for system administration by
    multiple people to know who wrote what, often to be able to ask
    questions, coordinate operations, etc.  This has limitations as
    SUDO_USER does not work when people login as root straight away, but
    this is better than nothing.

    carnet: handle carnet-specific lock files.
    
    This big change introduces the function setup_locks, which makes sure
    that there is no lock file open on a file under edition by carnet,
    also checking for common swap files from a couple of known text
    editors to avoid certain kind of incidents.  The implementation is not
    perfect but feels surprisingly good.  A part of the code is a bit
    messy, when hunting for information to display about the conflict when
    there is one occurring.
    
    WARNING: this function sets the LOCKFILE global variable and a trap on
    EXIT, so it can be invoked at most once during a carnet invocation.
    The trap also requires that the carnet script keeps running during all
    the time of the edition, so that the trap can trigger after the editor
    gives back the hand, for cleaning things up.  It's also been necessary
    to ensure the CARNET_DIR already exists prior invocation of
    setup_locks in the specific case of new carnets.

    concatenated to facilitate search over multiple keywords.

    carnet: apply sane default less behavior.
    
    Of course, this is about default behavior.  If the LESS environment
    variable exists, we don't touch that.  Also, this introduces the
    ability to pass less options specific to carnet via the CARNET_LESS
    environment variable.

    The shorthand `carnet -h` invocation will output a short usage message
    with an invitation to run `carnet --help` or read the manual for full

    The idea of this change is to preserve the readability of the usage
    notice even if the full help message has no chance to fit within a
    small terminal screen.

    behaving properly after having been deployed on a machine.

    carnet: limit trailing newlines within awk script.
    
    The hack with `sed '$d'` to trim the trailing newlines was not
    particularly clever.  It simplifies things to implement it within the
    awk script of the search_log function by clearing the output record
    separator (ORS) back to its default value.

    carnet: lightweight full search output.
    
    Prior to being handled specifically, a zero argument call to the
    search function would output the entire content of the carnet at all
    time.  However, the output would be invisibly cluttered with escape
    characters opening and closing highlight colors, making the resulting
    output ten to twenty times heavier than it should.  Matching /^/ would
    clean up the output substancially of its terminal escape sequences
    without blinding the end user with highlight color.

    The function is mostly useless at the moment, as it is preferrable to

    decoupling the terminfo_normal though.

    carnet: separate primitives from application logic.
    
    This is an attempt at thinning the glue layer between the top and
    bottom layers of the script.  Dependencies between functions have been
    removed where possible, and assembling of multiple functions is
    concentrated in the handles of the different commands of the carnet.
    Remaining identified interdependencies outside handles are:
    
            read_with_pager  -> is_less_friendly
            paint_timestamps -> terminfo_normal
            search_log       -> terminfo_normal
    
    Of course, the fact that the construction of base carnet entries
    themselves are outside the context of a shell function makes them hard
    to understand anyways.

    Be honest about depending on gawk.
    
    The current implementation is mostly operating properly only using
    gawk.  While some part of the --search function work somewhat with
    some alternate awk implementations, this is not tested near enough and
    it is more honest to make carnet depend on the full fledged GNU awk
    for now.  I'm not seeing myself fixing this any time soon, apart
    perhaps if one day I move the code to compiled language and lex/yacc.

    When using the root account, while not particularly recommended,
    handling a carnet specific to a system along its logs sounds like a
    legitimate use case, in which case /var/log/carnet looks to be a most
    appropriate default location, along system logs.
    
    This change modifies the carnet script and carnet_activity.pl in order
    to adjust to the new default value.

    invoking bare carnet, or when running --edit-feuillet.
    
    Note that this is by no means a perfect mitigation against lock files,
    since only vi-style files are handled for now, and given that it won't
    capture carnet's own editions, for the moment.

            use POSIX;
    
    and that this can be fixed with prefixing all the function with
    POSIX:: and import the functions using:
    
            use POSIX ();
    
    Since functions using POSIX were already namespaced in the script, the
    change was, thankfully, rather straightforward.

    carnet version 2, along changes to the file format to make the

    carnet: wire the --edit-feuillet option.
    
    The change actually allows the edition of an entry in place by passing
    the -ef, or --edit-feuillet, argument.  It also appends the
    documentation of the argument into the --help message.

    carnet: implement handle_edit_feuillet.
    
    The function allows editing in place a given existing entry by
    specifying it's time stamp.  If no time stamp is specified, then it
    edits the register.txt, which is thought of as a bookmark of time
    stamps, or registry.

    carnet: locate_feuillet to adjust only references.
    
    In preparation of providing the ability to edit existing entries in
    place, the function locate_feuillet is slightly adjusted to allow it
    to return only the filename and line number if requested so, instead
    of the full entry.  This is going to be useful for opening an editor
    right at the location of the entry.

    todo items as done.

    carnet: workaround tput sgr0 ^O on linux.
    
    When running carnet on the linux terminal, the one without any kind of
    graphical environment started, the output of tput sgr0 shows a stray
    ^O sequence after the normal escape which interferes with less
    execution on linux.  This change works around the problem by
    specifying the escape sequence manually when running on a linux
    terminal.  This is achieved by implementing the function
    terminfo_normal, which branches to tput sgr0 or manual sequencing for
    faulty terminals.

    carnet: print file name in dedicated line.
    
    While it is less clear that the file name is a file name (although the
    full path should sell it), this change actually greatly facilitates
    selection of the carnet week by a triple click of the line in the
    terminal.  This then streamlines passing the file name as argument of
    whichever editor is favored by the user; an even better option could
    be to jump straight at the right line in a pager or an editor, but
    this must be thought of carefully to not get in the way of navigating
    between entries to gather ideas.

    there, in order to preserve an upper bound to the size of generated

    what I'm doing wrong on that front.  Downgrading to more looks to work
    fairly enough so far.  The script also downgrades for unknown
    terminals, so I may give a spin to other ones.

    carnet: reinstate CARNET_PAGER.
    
    While the setting of a custom PAGER is now unenforced, the
    CARNET_PAGER remains relevant to override the behavior of the function
    that pipes copious function outputs through whicher pager is found on
    the system.  Removal of the custom pager was initially motivated by
    the fact that the handling of escape terminal sequences is more or
    less subject to luck when stepping outside the usual pagers available
    everywhere.  And even then, I noticed a tremendous version delta in
    less version from NetBSD 10 versus less version in Debian 13.

    carnet: ditch CARNET_PAGER handling.
    
    Handling custom pager has become a complicated topic due to the
    painting of carnet commands output when consulting entries in read
    only mode for various purposes: the whole past week, search results
    highlights and feuillet reference highlights.  This change drops the
    ability to customize the pager, trading the customizability for more
    robust handling.  The use of less is not mandatory per se, as more and
    cat are still used as fallbacks, but it is now highly encouraged.
    Hopefully, better knowledge of alternate pagers behavior may allow
    customizability of the pager for the carnet again in the future.

    carnet: output YYYY-MM-DDThh:mm with --search.
    
    In order to facilitate synergies with --feuillet, the --search command
    output is slightly adjusted in order to output timestamps of entries
    retrieved using the format YYYY-MM-DDThh:mm; the format is also
    highlighted whenever located within a feuillet, in order to facilitate
    the identification of such character string in the feuillet by quickly
    scanning through the entry.  This is not the ISO normalized format,
    because the second at which an entry has been written was not recorded
    historically.
    
    If it were necessary to redo this, I would probably record the full
    timestamp in an easy to copy and paste format straight into the
    carnet.  I had and still have slight concern that such a change could
    have mild detrimental effect on the readability of a journal read
    through during a week though.

    carnet: introduce the notion of feuillet.
    
    The carnet is made up of feuillets, each feuillet corresponds to one
    entry entered after an invocation of `carnet`.  This change introduces
    the function locate_feuillet which takes the timestamp of a feuillet
    in format YYYY-MM-DDThh:mm, and retrieves the corresponding feuillet
    in output.  This step is part of the not-so-innocent great plan to
    actually convert carnet to a Zettelkasten engine even though it was
    not intended to be such tool in the first place.

    carnet: more precise overtime calculation.
    
    The logic of the calculate_overtime function is strongly adjusted in
    order to provide a +/- 30 minutes in which the day is close to ending
    and then the overtime is not already frank yet.  The adjustment makes
    the window of uncertainty last one hour.

    carnet: more generic variable name for context.
    
    The trailing context historically stuck to showing what was playing on
    the radio.  Since it might be of interest to put other things here,
    like labels or various alerts, a more generic name is needed.

    The percentileplot function does the same as the decileplot, but for
    each percentile.  The ascii art is an attempt to emphasize hotspots
    for which a huge number of weeks shared the same pattern of activity.

    carnet_activity.pl: introduce decileplot.
    
    The subroutine decileplot ressembles the boxplot, but simply marks the
    position of each decile.  This is useful to determine possible week
    patterns by providing some kind of heatmap, especially if combined
    with percentiles.

    carnet: bump version to 1.1.0.
    
    New minor version is justified by the introduction of unrecommended
    interface carnet_activity.pl, so should not be an actual regression if
    reverting to older carnet versions, but anyways, that looks better
    this way.

    carnet: remove show_activity function.
    
    Now that the show_activity shell function has been replaced by the
    perl script, it can be removed from the shell script.  This
    tremendously drops the line count of the shell script to something
    more manageable.

    carnet: make use of carnet_activity.pl.
    
    Now that the perl script is available, the carnet may change
    implementation for its --activity option, and use the perl script
    instead of the shell function.

    carnet_activity.pl: new: reimplement --activity.
    
    The --activity option shows rapidly visible performance decrease when
    implemented in shell.  Also, the initial implementation didn't work on
    Berkeley systems.  At the cost of introducing a dependency to the perl
    interpreter and the complexity that comes with it and the language,
    this allows earning some missing performance and portability in the
    equation.
    
    Next step if further performances are needed is to redo a write, but
    in C language this time.  It will take even more time and may take a
    toll on portability though, so this is not in the plans yet.

    makefile: make archive independent of git.
    
    Implementation of the archive makefile target is adjusted in order to
    allow one to rebuild an archive even without the git tree.  This is
    useful at least as long as the git tree is not distributed.  This
    facilitates sharing modified versions of the carnet.

    This change allows avoiding reconstruction of the archive at the sign
    step when running sequencially:
    
            $ make archive
            $ make sign
    
    Initially, the rerun of the archival step was caused by having the
    tar.xz file recipe to depend on the phony clean target.

    makefile: facilitate archival and publication.
    
    This change introduces two new makefile targets: `make archive` will
    issue a tarball facilitating the transfer of the project tree of
    carnet around, and `make sign` will automate the production of a
    cryptographically signed archive of carnet using gpg.  This is useful
    for releasing the project publically.
