ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.7 is a general purpose data compression library.  All the code is
thread safe.  The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).

All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org).  A usage example

  The deflate format used by zlib was defined by Phil Katz.  The deflate and
  zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
  people who reported problems and suggested various improvements in zlib; they
  are too numerous to cite here.

.SH NAME
miniunzip - uncompress and examine ZIP archives
.SH SYNOPSIS
.B miniunzip
.RI [ -exvlo ]
zipfile [ files_to_extract ] [-d tempdir]
.SH DESCRIPTION
.B minizip
is a simple tool which allows the extraction of compressed file
archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
written as a demonstration of the
.IR zlib (3)
library and therefore lack many of the features of the
.IR unzip (1)
program.
.SH OPTIONS
A number of options are supported.  With the exception of
.BI \-d\  tempdir
these must be supplied before any
other arguments and are:
.TP
.BI \-l\ ,\ \-\-v
List the files in the archive without extracting them.
.TP
.B \-o
Overwrite files without prompting for confirmation.
.TP
.B \-x
Extract files (default).
.PP
The
.I zipfile
argument is the name of the archive to process. The next argument can be used
to specify a single file to extract from the archive.

Lastly, the following option can be specified at the end of the command-line:
.TP
.BI \-d\  tempdir
Extract the archive in the directory
.I tempdir
rather than the current directory.
.SH SEE ALSO
.BR minizip (1),
.BR zlib (3),
.BR unzip (1).
.SH AUTHOR
This program was written by Gilles Vollant.  This manual page was
written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
was added by Dirk Eddelbuettel <edd@debian.org>.

.SH NAME
minizip - create ZIP archives
.SH SYNOPSIS
.B minizip
.RI [ -o ]
zipfile [ " files" ... ]
.SH DESCRIPTION
.B minizip
is a simple tool which allows the creation of compressed file archives
in the ZIP format used by the MS-DOS utility PKZIP.  It was written as
a demonstration of the
.IR zlib (3)
library and therefore lack many of the features of the
.IR zip (1)
program.
.SH OPTIONS
The first argument supplied is the name of the ZIP archive to create or
.RI -o
in which case it is ignored and the second argument treated as the
name of the ZIP file.  If the ZIP file already exists it will be
overwritten.
.PP
Subsequent arguments specify a list of files to place in the ZIP
archive.  If none are specified then an empty archive will be created.
.SH SEE ALSO
.BR miniunzip (1),
.BR zlib (3),

   Providing output buffers larger than 32K to inflate() should provide a speed
   advantage, since only the last 32K of output is copied to the sliding window
   upon return from inflate(), and since all distances after the first 32K of
   output will fall in the output data, making match copies simpler and faster.
   The advantage may be dependent on the size of the processor's data caches.

   Providing output buffers larger than 32K to inflate() should provide a speed
   advantage, since only the last 32K of output is copied to the sliding window
   upon return from inflate(), and since all distances after the first 32K of
   output will fall in the output data, making match copies simpler and faster.
   The advantage may be dependent on the size of the processor's data caches.

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.7 is a general purpose data compression library.  All the code is
thread safe.  The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format)
and rfc1952.txt (gzip format).

All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org).  Two compiled

     inflateBack() does a raw inflate with a single call using a call-back
   interface for input and output.  This is more efficient than inflate() for
   file i/o applications in that it avoids copying between the output and the
   sliding window by simply making the window itself the output buffer.  This

   function trusts the application to not change the output buffer passed by
   the output function, at least until inflateBack() returns.

     inflateBackInit() must be called first to allocate the internal state
   and to initialize the state with the user-provided window buffer.
   inflateBack() may then be used multiple times to inflate a complete, raw
   deflate stream with each call.  inflateBackEnd() is then called to free the
   allocated state.

/*
     inflateBack() does a raw inflate with a single call using a call-back
   interface for input and output.  This is potentially more efficient than
   inflate() for file i/o applications, in that it avoids copying between the
   output and the sliding window by simply making the window itself the output
   buffer.  inflate() can be faster on modern CPUs when used with large
   buffers.  inflateBack() trusts the application to not change the output
   buffer passed by the output function, at least until inflateBack() returns.

     inflateBackInit() must be called first to allocate the internal state
   and to initialize the state with the user-provided window buffer.
   inflateBack() may then be used multiple times to inflate a complete, raw
   deflate stream with each call.  inflateBackEnd() is then called to free the
   allocated state.

** COMMAND: add

**
** Make arrangements to add one or more files or directories to the
** current checkout at the next commit.
**
** When adding files or directories recursively, filenames that begin
** with "." are excluded by default.  To include such files, add
** the "--dotfiles" option to the command-line.
**
** The --ignore option is a comma-separate list of glob patterns for files
** to be excluded.  Example:  '*.o,*.obj,*.exe'  If the --ignore option
** does not appear on the command line then the "ignore-glob" setting is

** used.
**
** The --case-sensitive option determines whether or not filenames should
** be treated case sensitive or not. If the option is not given, the default
** depends on the global setting, or the operating system default, if not set.
**
** Options:
**
**    --case-sensitive <BOOL> override case-sensitive setting
**    --dotfiles              include files beginning with a dot (".")   
**    --ignore <CSG>          ignore files matching patterns from the

**
** When adding files or directories recursively, filenames that begin

**
** The --ignore and --clean options are comma-separate lists of glob patterns

** the "clean-glob" setting is used.
**
** The --case-sensitive option determines whether or not filenames should
** be treated case sensitive or not. If the option is not given, the default
** depends on the global setting, or the operating system default, if not set.
**
** Options:
**

** COMMAND: bisect
**
** Usage: %fossil bisect SUBCOMMAND ...
**
** Run various subcommands useful for searching for bugs.
**
**   fossil bisect bad ?VERSION?
**
**     Identify version VERSION as non-working.  If VERSION is omitted,
**     the current checkout is marked as non-working.
**
**   fossil bisect good ?VERSION?
**
**     Identify version VERSION as working.  If VERSION is omitted,
**     the current checkout is marked as working.
**
**   fossil bisect log

**
**     Show a log of "good" and "bad" versions


**
**   fossil bisect next
**
**     Update to the next version that is halfway between the working and
**     non-working versions.
**
**   fossil bisect options ?NAME? ?VALUE?
**
**     List all bisect options, or the value of a single option, or set the
**     value of a bisect option.
**
**   fossil bisect reset
**
**     Reinitialize a bisect session.  This cancels prior bisect history
**     and allows a bisect session to start over from the beginning.
**
**   fossil bisect vlist|ls|status ?--all?
**
**     List the versions in between "bad" and "good".
**
**   fossil bisect undo
**
**     Undo the most recent "good" or "bad" command.
**
** Summary:
**
**   fossil bisect bad ?VERSION?
**   fossil bisect good ?VERSION?
**   fossil bisect log

**   fossil bisect next
**   fossil bisect options
**   fossil bisect reset
**   fossil bisect status

** COMMAND: bisect
**
** Usage: %fossil bisect SUBCOMMAND ...
**
** Run various subcommands useful for searching for bugs.
**
**   fossil bisect bad ?VERSION?
**
**     Identify version VERSION as non-working.  If VERSION is omitted,
**     the current checkout is marked as non-working.
**
**   fossil bisect good ?VERSION?
**
**     Identify version VERSION as working.  If VERSION is omitted,
**     the current checkout is marked as working.
**
**   fossil bisect log
**   fossil bisect chart
**
**     Show a log of "good" and "bad" versions.  "bisect log" shows the
**     events in the order that they were tested.  "bisect chart" shows
**     them in order of check-in.
**
**   fossil bisect next
**
**     Update to the next version that is halfway between the working and
**     non-working versions.
**
**   fossil bisect options ?NAME? ?VALUE?
**
**     List all bisect options, or the value of a single option, or set the
**     value of a bisect option.
**
**   fossil bisect reset
**
**     Reinitialize a bisect session.  This cancels prior bisect history
**     and allows a bisect session to start over from the beginning.
**
**   fossil bisect vlist|ls|status ?-a|--all?
**
**     List the versions in between "bad" and "good".
**
**   fossil bisect undo
**
**     Undo the most recent "good" or "bad" command.
**
** Summary:
**
**   fossil bisect bad ?VERSION?
**   fossil bisect good ?VERSION?
**   fossil bisect log
**   fossil bisect chart
**   fossil bisect next
**   fossil bisect options

** This function attempts to scan each logical line within the blob to

**
** !LOOK_BINARY -- The content appears to consist entirely of text; however,
**                 the encoding may not be UTF-8.
**
** LOOK_BINARY -- The content appears to be binary because it contains one
**                or more embedded NUL characters or an extremely long line.
**                Since this function does not understand UTF-16, it may
**                falsely consider UTF-16 text to be binary.
**
** Additional flags (i.e. those other than the ones included in LOOK_BINARY)
** may be present in the result as well; however, they should not impact the
** determination of text versus binary content.

** The only code points that this function cares about are the NUL character,
** carriage-return, and line-feed. For the algorithm use in CR/LF detection,

** Checks for proper UTF-8. It uses the method described in:
**   http://en.wikipedia.org/wiki/UTF-8#Invalid_byte_sequences
** except for the "overlong form" which is not considered
** invalid: Some languages like Java and Tcl use it. For UTF-8 characters
** > 7f, the variable 'c2' not necessary means the previous character.
** It's number of higher 1-bits indicate the number of continuation bytes
** that are expected to be followed. E.g. when 'c2' has a value in the range
** 0xc0..0xdf it means that 'c' is expected to contain the last continuation
** byte of a UTF-8 character. A value 0xe0..0xef means that after 'c' one
** more continuation byte is expected.

**                Since this function does not understand UTF-8, it may
**                falsely consider UTF-8 text to be binary.

**
************************************ WARNING **********************************
**
** This function does not validate that the blob content is properly formed
** UTF-16.  It assumes that all code points are the same size.
**
** The only code points that this function cares about are the NUL character,
** carriage-return, line-feed, 0xFFFE and 0xFFFF.
**
** The algorithm used is based on the importance of the relation between CR
** and LF as a pair. Assume that we have two consecutive characters available,
** 'c2' and 'c'. In the algorithm, we compare 'c2' with CR, and 'c' with LF
** in a loop. If both compares return as equal, we have a CRLF pair, other
** combinations result in LONE CR/LF characters. If 'c2' is not equal to CR,
** we compare it with NUL as well. Within the loop that gives 6 possible code
** paths while executing only 3 'if' statements. The only thing to watch out
** for is not to forget the first and the last characters of the blob: Those
** cannot be checked for inside the loop, because they cannot form a pair with
** characters outside the blob.
**
** For determining the LOOK_LONG flag, the UTF-8 length of the characters is
** taken. Surrogate pairs are not handled, which might result in a small
** (irrelevant) over-estimation of the real line length.
**
** The LOOK_UNICODE flag is incompatible with LOOK_NUL and LOOK_SHORT: Only
** when the blob is fully checked not to contain NUL characters it could
** be determined to possibly be UTF-16. The presence of LOOK_INVALID and
** LOOK_LONG is not taken into account for LOOK_UNICODE.
**
** This function examines the contents of the blob until one of the flags
** specified in "stopFlags" is set.

** The only code points that this function cares about are the NUL character,

** Checks for proper UTF-8. It uses the method described in:
**   http://en.wikipedia.org/wiki/UTF-8#Invalid_byte_sequences
** except for the "overlong form" which is not considered
** invalid: Some languages like Java and Tcl use it. For UTF-8 characters
** > 7f, the variable 'c2' not necessary means the previous character.
** It's number of higher 1-bits indicate the number of continuation bytes
** that are expected to be followed. E.g. when 'c2' has a value in the range
** 0xc0..0xdf it means that 'c' is expected to contain the last continuation
** byte of a UTF-8 character. A value 0xe0..0xef means that after 'c' one
** more continuation byte is expected.

**
** The only code points that this function cares about are the NUL character,
** carriage-return, line-feed, 0xFFFE and 0xFFFF.
**
** The algorithm used is based on the importance of the relation between CR
** and LF as a pair. Assume that we have two consecutive characters available,
** 'c2' and 'c'. In the algorithm, we compare 'c2' with CR, and 'c' with LF
** in a loop. If both compares return as equal, we have a CRLF pair, other
** combinations result in LONE CR/LF characters. If 'c2' is not equal to CR,
** we compare it with NUL as well. Within the loop that gives 6 possible code
** paths while executing only 3 'if' statements. The only thing to watch out
** for is not to forget the first and the last characters of the blob: Those
** cannot be checked for inside the loop, because they cannot form a pair with
** characters outside the blob.
**
** For determining the LOOK_LONG flag, the UTF-8 length of the characters is
** taken. Surrogate pairs are not handled, which might result in a small
** (irrelevant) over-estimation of the real line length.
**
** The LOOK_UNICODE flag is incompatible with LOOK_NUL and LOOK_SHORT: Only
** when the blob is fully checked not to contain NUL characters it could
** be determined to possibly be UTF-16. The presence of LOOK_INVALID and
** LOOK_LONG is not taken into account for LOOK_UNICODE.
**
** This function examines the contents of the blob until one of the flags
** specified in "stopFlags" is set.

**                           a sequence of changes in a branch to be merged

**
**   --detail                Show additional details of the merge
**
**   --binary GLOBPATTERN    Treat files that match GLOBPATTERN as binary
**                           and do not try to merge parallel changes.  This
**                           option overrides the "binary-glob" setting.
**
**   --nochange | -n         Dryrun:  do not actually make any changes; just
**                           show what would have happened.
**
**   --case-sensitive BOOL   Override the case-sensitive setting.  If false,
**                           files whose names differ only in case are taken
**                           to be the same file.
**
**   --force | -f            Force the merge even if it would be a no-op.

**                           without having to merge the entire branch.
**


**   --binary GLOBPATTERN    Treat files that match GLOBPATTERN as binary
**                           and do not try to merge parallel changes.  This
**                           option overrides the "binary-glob" setting.
**



**   --case-sensitive BOOL   Override the case-sensitive setting.  If false,
**                           files whose names differ only in case are taken
**                           to be the same file.
**
**   -f|--force              Force the merge even if it would be a no-op.

** Output Javascript code that will enables sorting of the table with
** the id zTableId by clicking.
**
** The javascript is derived from:
**
**     http://www.webtoolkit.info/sortable-html-table.html
**
** This variation allows column types to be expressed using the second
** argument.  Each character of the second argument represent a column.
** "t" means sort as text.  "n" means sort numerically.  "x" means do not
** sort on this column.  If there are fewer characters in zColumnTypes[] than
** their are columns, the all extra columns assume type "t" (text).

    **
    **  nInMul:  
    **    The "in-multiplier". This is an estimate of how many seek operations 
    **    SQLite must perform on the index in question. For example, if the

    **
    **      WHERE a IN (1, 2, 3) AND b IN (4, 5, 6)

    **      WHERE a =  1
    **      WHERE a >= 2
    **

    **    in determining the value of nInMul.  Note that the RHS of the
    **    IN operator must be a SELECT, not a value list, for this variable
    **    to be true.
    **
    **  rangeDiv:
    **    An estimate of a divisor by which to reduce the search space due
    **    to inequality constraints.  In the absence of sqlite_stat3 ANALYZE
    **    data, a single inequality reduces the search space to 1/4rd its
    **    original size (rangeDiv==4).  Two inequalities reduce the search
    **    space to 1/16th of its original size (rangeDiv==16).

    **    For other indexes, it is true unless all the columns of the table
    **    used by the SELECT statement are present in the index (such an
    **    index is sometimes described as a covering index).
    **    For example, given the index on (a, b), the second of the following 
    **    two queries requires table b-tree lookups in order to find the value
    **    of column c, but the first does not because columns a and b are
    **    both available in the index.
    **

** If an index can be used so that the natural output order of the table

    ** Since the cost of a linear scan through table t2 is the same 
    ** as the cost of a linear scan through table t1, a simple greedy 
    ** algorithm may choose to use t2 for the outer loop, which is a much
    ** costlier approach.

** This file contains code for the "fts3tokenize" virtual table module.
** An fts3tokenize virtual table is created as follows:

**
** The table created has the following schema:
**

**
** When queried, the query must include a WHERE clause of type:
**
**   input = <string>
**
** The virtual table module tokenizes this <string>, using the FTS3 
** tokenizer specified by the arguments to the CREATE VIRTUAL TABLE 
** statement and returns one row for each token in the result. With
** fields set as follows:
**
**   input:   Always set to a copy of <string>
**   token:   A token from the input.
**   start:   Byte offset of the token within the input <string>.
**   end:     Byte offset of the byte immediately following the end of the
**            token within the input string.
**   pos:     Token offset of token within input.

**  fossil stash snapshot ?-m|--comment COMMENT? ?FILES...?
**
**     Save the current changes in the working tree as a new stash.
**     Then revert the changes back to the last check-in.  If FILES
**     are listed, then only stash and revert the named files.  The
**     "save" verb can be omitted if and only if there are no other
**     arguments.  The "snapshot" verb works the same as "save" but
**     omits the revert, keeping the check-out unchanged.
**
**  fossil stash list ?-v|--verbose?
**  fossil stash ls ?-v|--verbose?
**
**     List all changes sets currently stashed.  Show information about
**     individual files in each changeset if -v or --verbose is used.
**
**  fossil stash show ?STASHID? ?DIFF-FLAGS?
**
**     Show the content of a stash
**
**  fossil stash pop
**  fossil stash apply ?STASHID?
**
**     Apply STASHID or the most recently create stash to the current
**     working check-out.  The "pop" command deletes that changeset from
**     the stash after applying it but the "apply" command retains the
**     changeset.
**
**  fossil stash goto ?STASHID?
**
**     Update to the baseline checkout for STASHID then apply the
**     changes of STASHID.  Keep STASHID so that it can be reused
**     This command is undoable.
**
**  fossil stash drop ?STASHID? ?-a|--all?
**  fossil stash rm   ?STASHID? ?-a|--all?
**
**     Forget everything about STASHID.  Forget the whole stash if the
**     -a|--all flag is used.  Individual drops are undoable but -a|--all
**     is not.
**
**  fossil stash diff ?STASHID?
**  fossil stash gdiff ?STASHID?
**
**     Show diffs of the current working directory and what that
**     directory would be if STASHID were applied.

<h2>Changes For Version 1.26 (as yet unreleased)</h2>















  *  Win32: Fossil now understands Cygwin paths containing one or more of
     the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in
     win32. This means that the win32 fossil.exe is better usable in a Cygwin
     environment. See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
  *  Cygwin: Fossil now understands win32 absolute paths starting with a drive
     letter everywhere. The default value of the "case-sensitive" setting is
     now FALSE.


  *  Enhancements to /timeline.rss, adding more flags for filtering
     results, including the ability to subscribe to changes made
     to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82].


  *  JSON API: added the 'status' command to report local checkout status.











<h2>Changes For Version 1.25 (2013-02-16)</h2>

<h2>Changes For Version 1.27 (as yet unreleased)</h2>
  *  Enhance the [/help?cmd=changes | fossil changes],
     [/help?cmd=clean | fossil clean], [/help?cmd=extras | fossil extras],
     [/help?cmd=ls | fossil ls] and [/help?cmd=status | fossil status] commands
     to restrict operation to files and directories named on the command-line.

<h2>Changes For Version 1.26 (2013-06-18)</h2>
  *  The argument to the --port option for the [/help?cmd=ui | fossil ui] and
     [/help?cmd=server | fossil server] commands can take an IP address in addition
     to the port number, causing Fossil to bind to just that one IP address.
  *  After prompting for a password, also ask if that password should be
     remembered.
  *  Performance improvements to the diff engine.
  *  Fix the side-by-side diff engine to work better with multi-byte unicode text.
  *  Color-coding in the web-based annotation (blame) display.  Fix the annotation
     engine so that it is no longer confused by time-warps.
  *  The markdown formatter is now available by default and can be used for
     tickets, wiki, and embedded documentation.
  *  Add subcommands "fossil bisect log" and "fossil bisect status" to the
     [/help?cmd=bisect | fossil bisect] command, as well as other bisect enhancements.
  *  Enhanced defenses that prevent spiders from using excessive CPU and bandwidth.
  *  Consistent use of the -n or --dry-run command line options.
  *  Win32: Fossil now understands Cygwin paths containing one or more of
     the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in
     win32. This means that the win32 fossil.exe is better usable in a Cygwin
     environment. See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
  *  Cygwin: Fossil now understands win32 absolute paths starting with a drive
     letter everywhere. The default value of the "case-sensitive" setting is
     now FALSE, except when case-sensitivity is enabled in the Windows kernel.
     See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive]
  *  Enhancements to /timeline.rss, adding more flags for filtering
     results, including the ability to subscribe to changes made
     to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82].
  *  Improved handling of the differences between case-sensitive and 
     case-insensitive filesystems.
  *  JSON API: added the 'status' command to report local checkout status.
  *  Fixes to the <tt>--args</tt> support and documented this feature in the help.
  *  Added [/stats_report] page.
  *  Added <tt>ym=YYYY-MM</tt> filter to the [/timeline?ym=2013-06].
  *  Fixed: <tt>config reset</tt> now re-installs default ticket report format.
  *  <tt>ssh://</tt> and <tt>file://</tt> protocols now ignore proxy settings.
  *  Added [/hash-color-test] web page.
  *  Cherry-pick merges are recorded internally (though no yet displayed on the
     timeline graph.)
  *  Bring in the latest versions of SQLite, zlib, and autosetup from upstream.

a single repository on the local disk drive.  You can tie two or more
source trees to a single repository if you want (though one
tree per repository is the most common configuration.)  So a
single repository can be associated with many source trees, but
each source tree is associated with only one repository.

Fossil source trees may not overlap.  A fossil source tree is identified

by a file named "_FOSSIL_" in the root directory of the source tree.  Every
file that is a sibling of _FOSSIL_ and every file in every subfolder is
considered potentially a part of the source tree.  The _FOSSIL_ file
contains (among other things) the pathname of the repository with which
the source tree is associated.  On the other hand, the repository has
no record of its source trees.  So you are free to delete a source tree
or move it around without consequence.  But if you move or rename or
delete a repository, then any source trees associated with that repository

such a way that it can be handed a set of artifacts in any

artifacts and reconstruct the complete development history of
a software project.

<h3>2.2 Manifests</h3>

At the root of a source tree is a special file called the
"manifest".  The manifest is a listing of all other files in
that source tree.  The manifest contains the (complete) artifact ID 
of the file and the name of the file as it appears on disk,
and thus serves as a mapping from artifact ID to disk name.  The artifact ID
of the manifest is the identifier for the entire check-in.  When
you look at a "timeline" of changes in fossil, the ID associated
with each check-in or commit is really just the artifact ID of the
manifest for that check-in.









<p>Fossil automatically generates a manifest whenever you "commit" 
a new check-in.  So this is not something that you, the developer,
need to worry with.  The format of a manifest is intentionally
designed to be simple to parse, so that if
you want to read and interpret a manifest, either by hand or
with a script, that is easy to do.  But you will probably never

<h3>2.2 Manifests</h3>

Associated with every check-in is a special file called the
"manifest".  The manifest is a listing of all other files in
that source tree.  The manifest contains the (complete) artifact ID 
of the file and the name of the file as it appears on disk,
and thus serves as a mapping from artifact ID to disk name.  The artifact ID
of the manifest is the identifier for the entire check-in.  When
you look at a "timeline" of changes in fossil, the ID associated
with each check-in or commit is really just the artifact ID of the
manifest for that check-in.

<p>The manifest file is not normally a real file on disk.  Instead,
the manifest is computed in memory by Fossil whenever it needs it.
However, the "fossil setting manifest on" command will cause the
manifest file to be materialized to disk, if desired.  Both Fossil
itself, and SQLite cause the manifest file to be materialized to disk
so that the makefiles for these project can read the manifest and
embed version information in generated binaries.

editing looks like before you check it in.

Finally, the <i>&lt;filename&gt;</i> element of the URL is the
pathname of the documentation file relative to the root of the source
tree.

The mimetype (and thus the rendering) of documentation files is 
determined by the file suffix.  Fossil currently understands 192
different file suffixes, including all the popular ones such as
".css", ".gif", ".htm", ".html", ".jpg", ".jpeg", ".png", and ".txt".

Documentation files whose names end in ".wiki" use the 
[/wiki_rules | same markup as wiki pages] -
a safe subset of HTML together with some wiki rules for paragraph
breaks, lists, and hyperlinks.  The ".wiki" and ".txt" pages




are rendered with the standard fossil header and footer added.

All other mimetypes are delivered directly to the requesting
web browser without interpretation, additions, or changes.

<h2>Examples</h2>

This file that you are currently reading is an example of
embedded documentation.  The name of this file in the fossil
source tree is "<b>www/embeddeddoc.wiki</b>".
You are perhaps looking at this
file using the URL:

   [http://www.fossil-scm.org/index.html/doc/tip/www/embeddeddoc.wiki].

The first part of this path, the "[http://www.fossil-scm.org/index.html]",
is the base URL.  You might have originally typed:
[http://www.fossil-scm.org/].  The web server at the www.fossil-scm.org
site automatically redirects such links by appending "index.html".  The
"index.html" file on www.fossil-scm.org is really a CGI script
(do not be mislead by the name) which runs the fossil web service in
CGI mode.  The "index.html" CGI script looks like this:

<blockquote><pre>
#!/usr/bin/fossil
repository: /fossil/fossil.fossil
</pre></blockquote>

This is one of three ways to set up a 
<a href="quickstart.wiki#serversetup">fossil web server</a>.

The "<b>/tip/</b>" part of the URL tells fossil to use
the documentation files from the check-in that was checked in most
recently.  If you wanted to see an historical version of this document,
you could substitute the name of a check-in for "<b>/tip/</b>".
For example, to see the version of this document associated with
check-in [9be1b00392], simply replace the "<b>/tip/</b>" with
"<b>/9be1b00392/</b>".  You can also substitute the symbolic name
for a particular version or branch.  For example, you might

editing looks like before you check it in.

Finally, the <i>&lt;filename&gt;</i> element of the URL is the
pathname of the documentation file relative to the root of the source
tree.

The mimetype (and thus the rendering) of documentation files is 
determined by the file suffix.  Fossil currently understands 197
different file suffixes, including all the popular ones such as
".css", ".gif", ".htm", ".html", ".jpg", ".jpeg", ".png", and ".txt".

Documentation files whose names end in ".wiki" use the 
[/wiki_rules | same markup as wiki pages] -
a safe subset of HTML together with some wiki rules for paragraph
breaks, lists, and hyperlinks. 
Documentation files ending in ".md" or ".markdown" use the
Markdown markup langauge.
Documentation files ending in ".txt" are plain text.
Wiki, markdown, and plain text documentation files
are rendered with the standard fossil header and footer added.
All other mimetypes (including ".html" files)
are delivered directly to the requesting
web browser without interpretation, additions, or changes.

<h2>Examples</h2>

This file that you are currently reading is an example of
embedded documentation.  The name of this file in the fossil
source tree is "<b>www/embeddeddoc.wiki</b>".
You are perhaps looking at this
file using the URL:

   [http://www.fossil-scm.org/index.html/doc/trunk/www/embeddeddoc.wiki].

The first part of this path, the "[http://www.fossil-scm.org/index.html]",
is the base URL.  You might have originally typed:
[http://www.fossil-scm.org/].  The web server at the www.fossil-scm.org
site automatically redirects such links by appending "index.html".  The
"index.html" file on www.fossil-scm.org is really a CGI script
(do not be mislead by the name) which runs the fossil web service in
CGI mode.  The "index.html" CGI script looks like this:

<blockquote><pre>
#!/usr/bin/fossil
repository: /fossil/fossil.fossil
</pre></blockquote>

This is one of three ways to set up a 
<a href="quickstart.wiki#serversetup">fossil web server</a>.

The "<b>/trunk/</b>" part of the URL tells fossil to use
the documentation files from the most recent trunk check-in.
If you wanted to see an historical version of this document,
you could substitute the name of a check-in for "<b>/trunk/</b>".
For example, to see the version of this document associated with
check-in [9be1b00392], simply replace the "<b>/trunk/</b>" with
"<b>/9be1b00392/</b>".  You can also substitute the symbolic name
for a particular version or branch.  For example, you might
replace "<b>/trunk/</b>" with "<b>/experimental/</b>" to get the latest
version of this document in the "experimental" branch.  The symbolic name
can also be a date and time string in any of the following formats:</p>

<ul>
<li> <i>YYYY-MM-DD</i>
<li> <i>YYYY-MM-DD</i><b>T</b><i>HH:MM</i>
<li> <i>YYYY-MM-DD</i><b>T</b><i>HH:MM:SS</i>
</ul>

</blockquote>

The file that encodes this document is stored in the fossil source tree under
the name "<b>www/embeddeddoc.wiki</b>" and so that name forms the
last part of the URL for this document.

As I sit writing this documentation file, I am testing my work by
running the "<b>fossil server</b>" command line and viewing
<b>http://localhost:8080/doc/ckout/www/embeddeddoc.wiki</b> in
Firefox.  I am doing this even though I have not yet checked in
the "<b>www/embeddeddoc.wiki</b>" file for the first time.  Using
the special "<b>ckout</b>" version identifier on the "<b>/doc</b>" page
it is easy to make multiple changes to multiple files and see how they all
look together before committing anything to the repository.

<h1>Integrating Fossil in the Microsoft Express 2010 IDE</h1>

<i>Contributed by Gilles Ganault on 2013-05-24.</i>

The Express version of Visual Studio doesn't support add-in's and plug-in's,
but it's not an issue since it's still possible to use Fossil through the
External Tools menu and Fossil is a CLI application anyway:

<ol type="1">
    <li>Tools &gt; Settings &gt; Expert Settings</li>
    <li>Tools &gt; External Tools, where the items in this list map
        to "External Tool X" that we'll add to our own Fossil
        menu later: </li>
    <ol type="1">
        <li>Rename the default "&#91;New Tool 1&#93;" to eg.
        "Commit"&nbsp;&nbsp;&nbsp;2. 
        </li>
        <li>Change Command to where Fossil is located eg.
            "c:\fossil.exe"</li>
        <li>Change Arguments to the required command, eg.
            "commit -m". 
        The user will be prompted to type the comment that Commit expects</li>
        <li>Set "Initial Directory" to point it to the work directory 
        where the source files are currently checked out
        by Fossil (eg. c:\Workspace). It's also possible to use system
        variables such as "$(ProjectDir)" instead of hard-coding the path</li>
        <li>Check "Prompt for arguments", since Commit
        requires typing a comment. Useless for commands like Changes
        that don't require arguments</li>
        <li>Uncheck "Close on Exit", so we can see what Fossil says 
        before closing the DOS box. Note that "Use Output Window" 
        will display the output in a child window within the IDE instead of 
        opening a DOS box</li>
        <li>Click on OK</li>
    </ol>
    <li>Tools &gt; Customize &gt; Commands</li>
    <ol type="1">
        <li>With "Menu bar = Menu Bar" selected, click on "Add 
        New Menu". A new "Fossil" menu is displayed in the
        IDE's menu bar</li>
        <li>Click on "Modify Selection" to rename it
        "Fossil", and...</li>
        <li>Use the "Move Down" button to move it lower in
        the list</li>
    </ol>
    <li>Still in Customize dialog: In the "Menu bar" combo, select 
    the new Fossil menu you just created, and Click on "Add Command...": 
    From Categories, select Tools, and select "External Command 1". 
    Click on Close. It's unfortunate that the IDE doesn't say which command 
    maps to "External Command X".</li>
</ol>

<title>Fossil Tips And Usage Hints</title>

  1.  Click on nodes of any timeline graph to see diffs between two
      selected versions.

  2.  Add the "--tk" option to "[/help?cmd=diff | fossil diff]" commands 
      to get a pop-up
      window containing a complete side-by-side diff.  (NB:  The pop-up
      window is run as a separate Tcl/Tk process, so you will need to 
      have Tcl/Tk installed on your machine for this to work.  Visit
      [http://www.activestate.com/activetcl] to for a quick download of
      Tcl/Tk if you do not already have it on your system.)

  3.  The "[/help?cmd=clean | fossil clean -f]" command makes a great 
      alternative to "make clean".
  
  4.  Use "[/help?cmd=all | fossil all changes]" to look for any uncommitted 
      edits in any of your Fossil projects.  Use 
      "[/help?cmd=all | fossil all sync]" on your laptop
      prior to going off network (for example, on a long plane ride)
      to make sure you have all of content local.
  
  5.  Sub-menu options on Timelines lets you select either 20 or 200
      records.  But you can manual edit the "n=" query parameter in the
      URL to get any number of records you desire.  To see a complete
      timeline graph, set n to some ridiculously large value like 10000000.
  
  6.  You can manually add a "c=CHECKIN" query parameter to the timeline
      URL to get a snapshot of what was going on about the time of some
      checkin.  The "CHECKIN" can be
      [./checkin_names.wiki | any valid check-in or version name], including
      tags, branch names, and dates.  For example, to see what was going 
      on in the Fossil repository on 2008-01-01, visit
      [http://www.fossil-scm.org/fossil/timeline?c=2008-01-01].
  
  7.  Further to the previous two hints, there are lots of query parameters
      that you can add to timeline pages.  The available query parameters
      are tersely documented [/help?cmd=/timeline | here].
  
  8.  You can run "[/help?cmd=test-diff | fossil test-diff --tk $file1 $file2]"
      to get a pop-up  window with side-by-side diffs of two files, even if 
      neither of the two files is part of any Fossil repository.  Note that 
      this command is "test-diff", not "diff".
  
  9.  On web pages showing the content of a file (for example
      [http://www.fossil-scm.org/fossil/artifact/c7dd1de9f]) you can manually
      add a query parameter of the form "ln=FROM,TO" to the URL that
      will cause the range of lines indicated to be highlighted.  This
      is useful in pointing out a few lines of code using a hyperlink
      in a email or text message.  Example:
      [http://www.fossil-scm.org/fossil/artifact/c7dd1de9f?ln=28,30].
      Adding the "ln" query parameter without any argument simply turns
      on line numbers.   This feature only works right with files with
      a mimetype of text/plain, of course.
  
  10.  When editing documentation to be checked in as managed files, you can
       preview what the documentation will look like by using the special
       "ckout" branch name in the "doc" URL while running "fossil ui".
       See the [./embeddeddoc.wiki | embedded documentation] for details.

<title>Fossil Settings</title>

<h2>Using Fossil Settings</h2>

Settings control the behaviour of fossil. They are set with the <tt>fossil settings</tt> command, or through the web interface in the Settings page in the Admin section.



For a list of all settings, view the Settings page, or type <tt>fossil help settings</tt> from the command line.



<h3>Repository settings</h3>

Settings are set on a per-repository basis. When you clone a repository, a subset of settings are copied to your local repository.


If you make a change to a setting on your local repository, it is not synced back to the server when you <tt>push</tt> or <tt>sync</tt>. If you make a change on the server, you need to manually make the change on all repositories which are cloned from this repository.




You can also set a setting globally on your local machine. The value will be used for all repositories cloned to your machine, unless overridden explicitly in a particular repository. Global settings can be set by using the <tt>-global</tt> option on the <tt>fossil settings</tt> command.





<h3>"Versionable" settings</h3>

Most of the settings control the behaviour of fossil on your local machine, largely acting to reflect your preference on how you want to use Fossil, how you communicate with the server, or options for hosting a repository on the web. 




However, for historical reasons, some settings affect how you work with versioned files. These are <tt>allow-symlinks</tt>, <tt>binary-glob</tt>, <tt>crnl-glob</tt>, <tt>empty-dirs</tt>, <tt>encoding-glob</tt>, <tt>ignore-glob</tt> and <tt>manifest</tt>. The most important is <tt>ignore-glob</tt> which specifies which files should be ignored when looking for unmanaged files with the <tt>extras</tt> command.







Because these options can change over time, and the inconvenience of replicating changes, these settings are "versionable". As well as being able to be set using the <tt>settings</tt> command or the web interface, you can created versioned files in the <tt>.fossil-settings</tt> directory named with the setting name. The contents of the file is the value of the setting, and these files are checked in, committed, merged, and so on, as with any other file.







Where a setting is a list of values, such as <tt>ignore-glob</tt>, you can use a newline as a separator as well as a comma.


For example, to set the list of ignored files, create a <tt>.fossil-settings/ignore-glob</tt> file where each line contains a glob for ignored files.



If you set the value of a setting using the <tt>settings</tt> command as well as a versioned file, the versioned setting will take precedence. A warning will be displayed.

The second concern states that Fossil does not use a high-level scripting
language.  But that is not true.  Fossil uses SQL (as implemented by SQLite) 
as its scripting language.

This misunderstanding likely arises because people fail
to appreciate that SQL is a programming language.  People are taught that SQL
is a "query language" as if that were somehow different from a
"programming language".  But they really are two different favors of the
same thing.  I find that people do better with SQL if they think of
SQL as a programming language and each statement

The second concern states that Fossil does not use a high-level scripting

most other programming languages one specifies <i>how</i>
to carry out the computation.
