Introduction
\end_layout

\begin_layout Standard
This manual documents some aspects of \SpecialChar LyX
 development.
 It is currently rather incomplete, but will hopefully be extended in the
 future.
 Meanwhile, additional information can be found in the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
development
\end_layout

\end_inset

 subfolder of the \SpecialChar LyX
 source code distribution.
 This document is not translated, since the development language of \SpecialChar LyX
 is
 English.
 If you just want to use \SpecialChar LyX
, then you don't need to read this manual.
 However, if you want to learn more about how \SpecialChar LyX
 is developed, or even want
 to participate in \SpecialChar LyX
 development, you may find some interesting information
 here.
\end_layout

\begin_layout Section
File formats
\end_layout

\begin_layout Standard
\SpecialChar LyX
 uses several custom file formats for configuration files and documents.
 This chapter contains some background concerning these file formats.
 Several file formats are also described in detail in the regular user documenta
tion.

When is an update of the .lyx file format number needed?
\begin_inset CommandInset label

\end_inset


\end_layout

\begin_layout Standard
When you are working on a new feature you may ask yourself whether it needs
 an update of the .lyx file format number.
 Whether an update is needed or not is not always obvious.
 Rule of thumb: 
\end_layout

\begin_layout Quote
Whenever there is the danger that a previous version of LyX cannot open
 a file using the new feature, a file format update is needed.
\end_layout

\begin_layout Standard
The file format change allows lyx2lyx rules to implement backwards compatibility.
 Below you can find a list of reasons for file format updates with explanations:
\end_layout

\begin_layout Description

package The reason for this is that there is no true ERT inset for math
 formulas: Each command is parsed, and if a user happens to define a local
 command with the same name as a command that triggers an automatic load
 of a package, they need to be able to switch off the automatic loading
 of that package.
 This switch is stored by the

How to update the file format number of .lyx files
\end_layout

\begin_layout Standard
Once you come to the conclusion that a file format update is needed, you
 should use the following procedure to perform the update:
\end_layout

\begin_layout Enumerate
Implement and test the new feature, including the reading and writing of
 .lyx files.
 Note that any file produced at this stage does not use a valid format,
 so do not use this version of \SpecialChar LyX
 for working on any important documents.
\end_layout

\begin_layout Enumerate

name "enu:Describe_format"

\end_inset

\begin_layout Enumerate
\begin_inset CommandInset label

name "enu:Add-an-entry"

\end_inset

Add an entry to both format lists (for conversion and reversion) in
\begin_inset Newline newline
\end_inset


\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
lib/lyx2lyx/lyx_2_3.py
\end_layout

\end_inset

.
 Add a conversion routine if needed (e.
\begin_inset space \thinspace{}
\end_inset

g., a new header setting always needs a conversion that adds the new setting,
 but a new document language does not need one).
 Add a reversion routine if needed.
 
\begin_inset Newline newline
\end_inset

While the conversion routine is required to produce a document that is equivalen
t to the old version, the requirements of the reversion are not that strict.
 If possible, try to produce a proper reversion, using ERT if needed, but
 for some features this might be too complicated.
 In this case, the minimum requirement of the reversion routine is that
 it produces a valid document which can be read by an older \SpecialChar LyX
.
 If absolutely needed, even data loss is allowed for the reversion.
 (In that case, you might want to add a LyX comment that indicates what
 you have had to do, so the user is at least warned).
\end_layout

\begin_layout Enumerate
Since tex2lyx has several implicit file format dependencies caused by sharing
 code with \SpecialChar LyX
, updating the file format of .lyx files produced by tex2lyx at
 the same time as updating the main .lyx file format is strongly recommended.
 Therefore, a compiler warning will be issued if the \SpecialChar LyX
 and tex2lyx .lyx file
 format numbers differ.
 In many cases the tex2lyx update requires only the first and last item
 of the list below:

\begin_layout Plain Layout
src/version.h
\end_layout

\end_inset

.
\end_layout

\begin_layout Enumerate
If the lyx2lyx conversion from the old to the new format is empty, or if
 tex2lyx does not yet output the changed feature, you do not need any further
 tex2lyx changes.
 Otherwise, search for the changed feature in tex2lyx, and adjust the output
 according to the lyx2lyx changes.
\end_layout

\begin_layout Enumerate
Update the tex2lyx test references as described in 
\begin_inset CommandInset ref
LatexCommand formatted
reference "sec:Updating-test-references"

\end_inset

.
\end_layout

\end_deeper
\begin_layout Enumerate
If you did not implement full tex2lyx support for the new feature, add a
 line to 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
src/tex2lyx/TODO.txt
\end_layout

\end_inset

 describing the missing bits.
 Note that it is perfectly fine if you do not add full tex2lyx support for
 a new feature: The updating recommendation above is only issued for the
 syntax of the produced .lyx file.
 It is no problem if some features supported by \SpecialChar LyX
 are still output as ERT
 by tex2lyx.
 The problems in the past that resulted in the update recommendation were
 related to mixed version syntax, not ERT.
\end_layout

\begin_layout Enumerate
It would be nice if you could create a .lyx test file which contains instances
 of all changed or added features.
 This could then be used to test lyx2lyx and tex2lyx.
 Unfortunately, it has not yet been decided how to collect such examples,
 so please ask on the development list if you want to create one.
\end_layout

\begin_layout Enumerate
\begin_inset CommandInset label
LatexCommand label
name "enu:updatefiles"

\end_inset

Update LyX's .lyx documentation files to the new format.
 The developer who makes the change knows best what changes to expect when
 inspecting the resulting diff.
 Because of this, you might be able to catch a bug in the lyx2lyx code that
 updates the format just by taking a quick scan through the large diff that
 is the result.
\begin_inset Note Note
status collapsed

\begin_layout Plain Layout
Another advantage is that if later we suspect a bug in lyx2lyx we can easily
 see which layout update made an unexpected change by looking at the git
 log of a .lyx file that suffers the problem.
\end_layout

\end_inset

 To do this, first make sure that there are no changes to the git repository
 that you will not want to commit (this is needed because it will be convenient
 to commit with the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
git commit -a
\end_layout

\end_inset

).
 Then run the following command in the root folder of the source: 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
python development/tools/updatedocs.py
\end_layout

\end_inset

.
 Look at the resulting changes using the command 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
git diff
\end_layout

\end_inset

.
 If anything looks surprising, please investigate.
 Keep in mind that the case of 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
LFUNs.lyx
\end_layout

\end_inset

 is special, because it is first generated with 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
gen_lfuns.py
\end_layout

\end_inset

 before being converted to the latest format.
 Finally, commit using 
\begin_inset Flex Code

\begin_layout Standard
Note that we do not automatically any local layout used in the 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
.lyx
\end_layout

\end_inset

 files shipped with \SpecialChar LyX
 because users would then not be able to export to older
 formats.
 For example, if a 2.2.0 user exported a template to 2.1.x format and tried
 to open the file in \SpecialChar LyX
 2.1.x, there would be an error because the file would
 contain a local layout whose format is too new.
 The root reason for this is that we do not support converting layouts to
 older layout formats, as we do for the 
\begin_inset Flex Code

\begin_layout Plain Layout

\end_inset

 file format.
\end_layout

\begin_layout Subsection
Updating the file format number of bind/ui files

 The latter cannot be done automatically and also requires an update of

Backporting new styles to the stable version

\end_inset


\end_layout

\begin_layout Standard
Starting with the stable \SpecialChar LyX
 2.1 branch, there is a mechanism in place to backport
 new styles to the stable version without the need to update the file format.
 The basic idea is that the new style definition is automatically copied
 to the document preamble so that it can even be used by older minor versions
 that did not yet include the style.
 To backport a new style to the stable version, the following steps are
 needed:
\end_layout

\begin_layout Enumerate
Add the line 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
ForceLocal -1
\end_layout

\end_inset

 to the style definition in the development version.
\end_layout

\begin_layout Enumerate
Copy the style definition to the stable version, but use 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
ForceLocal 1
\end_layout

\end_inset

 instead.
 If needed adjust the format to the one used by the stable version (see
 the customization manual for details of the layout file format).
\end_layout

\begin_layout Enumerate
For each update of the style in a later stable version, increase the argument
 of 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
ForceLocal
\end_layout

\end_inset

 by one.
 (In the stable version, the development version should not be touched.)

 flag see the customization manual.
 No 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout
lyx2lyx
\end_layout

\end_inset

 support is needed for backported styles: Since the style of the development
 version has an infinite version number, it will always be used.
 Furthermore, since its version number is less than one, the style will
 not be written anymore to the document header for files saved by the new
 version.

\begin_layout Plain Layout
Uwe has suggested we implement automatic detection of changes in class files.
 This could be done by running a script every month that checks if a document
 class was changed at CTAN and at the homepages of the scientific journals.
 If it reports a change, we can check if our template and layout file are
 still usable with the changed document class.
 (This is different from the autotests insofar, as this would also catch
 changes that do not result in compilation errors.)
\end_layout

\end_inset

 Reasons can be a new name for the

 How should this best be handled in \SpecialChar LyX
? 
\end_layout

\begin_layout Standard
The idea is to support the new version with a new \SpecialChar LyX
 layout so that:
\end_layout

\begin_layout Itemize
Existing documents can still be opened in \SpecialChar LyX
 and will continue to work on
 systems where the old version is still installed.
 
\end_layout

\begin_layout Itemize
With differently named 
\begin_inset Flex Code
status collapsed

\begin_layout Plain Layout

\end_layout

\end_inset

 files, \SpecialChar LyX
 can check for the availability of the particular version and reflect
 this in the GUI.
 Different document class versions with the same file name are currently
 (2.2.x) not detected by the configuration script.
 This is planned for 2.3.

However, what we really need is version detection for the configuration,
 so that the user can be warned if the required class file has the wrong

 (If the class file keeps the name over the version change, only one of
 the two layout files generates compilable documents.)

 No lyx2lyx conversion is then required when a new major version is released.

The user can move an existing document to the new version simply by selecting
 a new document class.
 This step is well supported by \SpecialChar LyX

 This way, no lyx2lyx code is required.
\end_layout

\begin_layout Standard
The steps to support a new version of an existing document class are thus:
\end_layout

 special characters like spaces and dots), e.g.

\begin_layout Standard
It may be tempting to let the new layout be the

 However, this should not be done because any changes to the new layout

 Each test consists of two files:

 The test machinery is also able to generate a file 
\begin_inset Flex Code

 When in the

\begin_inset Flex Code

 Alternatively, in the root of the build directory, the command 
\begin_inset Flex Code

\end_layout

\end_inset

 runs all tests whose names match the regex 
\begin_inset Quotes eld
\end_inset

tex2lyx
\begin_inset Quotes erd

.
 Another way to run the tex2lyx tests in the root build directory is to
 instead use the command 
\begin_inset Flex Code

\begin_layout Plain Layout
ctest -L '(cmplyx|roundtrip)'
\end_layout

\end_inset

roundtrip
\begin_inset Quotes erd
\end_inset

 or 
\begin_inset Quotes eld

cmplyx

 If a test fails, the differences between the expected and actual results
 are output in unified diff format.

\begin_inset Flex Code

\begin_layout Plain Layout
src/tex2lyx/test/<test name>.tex

Export tests 
\end_layout

\begin_layout Standard
The export tests are integration tests.
 They take longer to run and are more likely to break than the tex2lyx tests.
 Nevertheless, they have caught many regressions and without a better alternativ
e it is important to keep them up-to-date and understand how they work.
\end_layout

\begin_layout Standard
The export tests

Expectations of LyX developers
\end_layout

\begin_layout Standard
Because the export tests are integration tests and take a long time to run,
 LyX developers are rarely expected to run all of the tests.
 Here are some good practices to follow by developers:
\end_layout

\begin_layout Itemize
When making a non-trivial change to a .layout file, run the export and layout
 tests corresponding with that .layout file.
\end_layout

\begin_layout Itemize
When making non-trivial changes to a .lyx file, run the export tests correspondin

 the documentation must not be complicated by having to consider non-standard
 exports.

successful compiling/testing an edited documentation file with pdflatex
 suffices to ensure it can be commited, not tests with other exports are
 required.
\end_layout

\begin_layout Plain Layout
If sudden failures with other exports due to “half-tested” documentation
 updates are a problem for the test maintainer, the test suite should use
 copies that are 
\end_layout

\begin_layout Itemize
copied to a cache dir (autotests/samples/doc/, say) but not changed,
\end_layout

\begin_layout Itemize
updated regularely (but on a time chosen by the test suite maintainer) from
 the originals in lib/doc/
\end_layout

\begin_layout Plain Layout
This way, 
\end_layout

\begin_layout Itemize
no test will fail due to ongoing work on documentation,
\end_layout

\begin_layout Itemize
the documentation is still tested in full (with some delay),
\end_layout

\begin_layout Itemize
failures with non-default export can be examined and handled accordingly
 in one run with the cache update,
\end_layout

\begin_layout Itemize
“interesting failures” (like the nested-language+polyglossia problem in

\begin_layout Standard
A good question is why do we enable the tests for non-default formats? The
 answer is that if a non-default route is broken it is often because a bug
 was introduced in LyX and not because a document-specific change was made
 that is not supported by the route.
 In other words, there is a high signal/noise ratio in the export tests
 for some non-default formats.

\begin_layout Subsubsection
check_load tests
\end_layout

\begin_layout Standard
These tests check whether a .lyx file loads without any terminal messages.
 They correspond to the manual operations of simply opening a .lyx file on
 the terminal, exiting LyX once the file is loaded, and then checking whether
 there is any output from the terminal.
 These tests are useful for catching malformed .lyx files and parsing bugs.
 They can also be used to find a .lyx file in which an instance of something
 happens.
 To do this, compile LyX with a local patch that outputs something to the
 terminal when an instance is found, and then run the check_load tests to
 see if any fail, which would mean that the situation occurs in the LyX
 documentation files corresponding to the failed tests.
 These tests are expectedly fragile: any LyX diagnostic message, which is
 not necessarily an error, would cause the tests to fail.
 Similarly, any message output by a library (e.g.
 Qt) would also cause failure.
 There are some messages that the check_load tests are instructed to ignore,
 which are stored in the file 
\begin_inset Flex Code

\begin_layout Plain Layout

.
\end_layout

\begin_layout Standard
Under cmake, the tests are labeled as 'load'.
\end_layout

\begin_layout Subsubsection
Keytests
\end_layout

\begin_layout Standard
Automated tests based on the "MonKey Testing" keytest program are enabled
 if the necessary dependencies are found and if the CMake flag

\begin_layout Subsubsection
lyx21 tests
\end_layout

\begin_layout Standard
These tests combine lyx2lyx tests with check_load tests.
 They fail if either fails.
\end_layout

\begin_layout Subsubsection
URL tests
\end_layout

\begin_layout Standard
The URL tests are enabled with the

\begin_layout Plain Layout
-DLYX_ENABLE_URLTESTS=ON

 CMake flag and are useful for finding broken links in our documentation
 files.
 If a URL test fails, to see which link in particular was reported as broken,
 see the output in 
\begin_inset Flex Code

\begin_layout Plain Layout
LastTest.log
\end_layout

\end_inset

.
 These tests are extremely fragile (e.g.
 a test can depend on your Internet connection) and a failed URL test should
 not be taken too seriously.
 URL tests are labeled as 
\family typewriter
'url'.
\end_layout

\begin_layout Paragraph
Running URL tests
\end_layout

\begin_layout Standard
cmake is required to run the \SpecialChar LyX
 tests, running them is not implemented for
 autotools.
\end_layout

\begin_layout Standard
The appropriate commands are:
\end_layout

\begin_layout Itemize

\family typewriter
ctest -L url
\family default

\begin_inset Newline newline
\end_inset

runs all tests with label 
\family typewriter
'url'
\end_layout

\begin_layout Itemize

\family typewriter
ctest -R 'check_.*urls'
\family default

\begin_inset Newline newline
\end_inset

runs the tests 'check_accessible_urls'
\end_layout

\begin_layout Standard
Associated test results can be examined in ctest-log directory in files
 of the form 'LastFailed.*URLS.log'
\end_layout

\begin_layout Section
Development policies
\end_layout

\begin_layout Standard
This chapter lists some guidelines that should be followed.
 This list is not complete, and many guidelines are in separate chapters,
 such as 
\begin_inset Quotes eld
\end_inset

When is an update of the .lyx file format number needed?
\begin_inset Quotes erd

 in Section 
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:When-is-an"

\end_inset

.
\end_layout

\begin_layout Subsection
When to set a fixed milestone?
\end_layout

\begin_layout Standard
Only set a fixed milestone (like 2.1.4 or 2.2.0) if at least one of the following
 holds:
\end_layout

\begin_layout Enumerate
Somebody is actively working on a fix.
\end_layout

\begin_layout Enumerate
The bug is so severe that it would block the release if it is not fixed.
\end_layout

\begin_layout Standard
If a bug is important, but nobody is working on it, and it is no showstopper,
 use a milestone like 2.1.x or 2.2.x.
 For all other bugs, do not set a milestone at all.
\end_layout

\begin_layout Subsection
Can we add rc entries in stable branch?
\end_layout

\begin_layout Standard
No.
 We are supposed to increase the prefs2prefs version number with such things.
\end_layout

\begin_layout Section
Documentation policies
\end_layout

\begin_layout Subsection
Rules
\end_layout

\begin_layout Standard
There are 6
\begin_inset space ~
\end_inset

rules in editing the docs:
\end_layout

\begin_layout Enumerate
\begin_inset CommandInset label
LatexCommand label
name "enu:If-you-are"

\end_inset

If you are not the maintainer of a doc file or a chapter/section, you MUST
 use change tracking so that the maintainer could review your changes
\end_layout

\begin_layout Enumerate
Respect the formatting of the document.
 The different files use different formatting styles.
 That is OK and has historic reasons nobody fully knows ;-).
 But it is important to be consistent within one file.
\end_layout

\begin_layout Enumerate
All changes you make to a file in one language MUST also go the file in
 the other actively maintained languages.
 Normally the maintainer does this for you, if you are the maintainer, you
 must do this by copying or changing the changed or added text to the other
 files so that the translators sees the blue underlined text and know what
 they have to translate and what was changed.
\end_layout

\begin_layout Enumerate
You MUST assure that the document is compilable as 
\begin_inset Quotes eld
\end_inset

PDF (pdflatex)
\begin_inset Quotes erd
\end_inset

 or the document's default output format after your changes.
\end_layout

\begin_layout Enumerate
All fixes (typos, compilation fixes, updates info etc.) go at first into
 the current GIT branch because the user should benefit from all fixes with
 every minor release.
 Feel free to commit directly to branch as long as you follow rule
\begin_inset space ~
\end_inset


\begin_inset CommandInset ref
LatexCommand ref
reference "enu:If-you-are"

\end_inset

.
 You can immediately commit to master as well.
\end_layout

\begin_layout Enumerate
The fileformat of a file must not be changed unless you document a new feature
 in LyX that requires a new fileformat.
 The reason for this rule is to keep it easy for the doc maintainers to
 port/backport changes to from master/branch.
\end_layout

\begin_layout Standard
The main documentation consists of these files:
\end_layout

\begin_layout Description
splash.lyx it is the first file you see after an installation.
 We assume that a new user sees this.
 It is therefore designed to be as simple as possible.
 Therefore please don't add any new formatting, only fix typos etc.
 Splash.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe Stöhr.
\end_layout

\begin_layout Description
Intro.lyx This is the manual new users will read to learn \SpecialChar LyX
.
 It therefore uses a limited set of formatting.
 For example a standard document class.
 Since new users will first learn about the formatting possibilities of
 \SpecialChar LyX
 please keep this file that simple.
 Intro.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe Stöhr.
\end_layout

\begin_layout Description
Tutorial.lyx our tutorial.
 It must be always up to date.
 Normally there is nothing to add since we don't want to overwhelm new users
 with too much details.
 The will learn these details while using \SpecialChar LyX
 and we have special manuals.
 Tutorial.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe Stöhr.
\end_layout

\begin_layout Description
UserGuide.lyx our main user guide.
 It covers a mixture of basic and detailed information.
 Some information is also in the Math and EmbeddedObjects manual so that
 the UserGuide refers to these files.
 UserGuide.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe Stöhr.
\end_layout

\begin_layout Description
EmbeddedObjects.lyx a special manual to explain things like tables floats
 boxes etc.
 in all detail.
 EmbeddedObjects.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe
 Stöhr.
\end_layout

\begin_layout Description
Math.lyx a special manual to explain everything regarding math in all detail.
 Math.lyx is up to date for \SpecialChar LyX
 2.1.x, currently maintained by Uwe Stöhr.
\end_layout

\begin_layout Description
Additional.lyx this manual covers information that would be too much detail
 for the UserGuide or would make the UserGuide uncompilable or only compilable
 when installing a lot of special \SpecialChar LaTeX
-packages.
 What should be in the UserGuide or better in Additional is a matter of
 taste.
 it is up to you to decide that.
 Additional.lyx is not completely up to date for \SpecialChar LyX
 2.1.x.
 Only chapter
\begin_inset space ~
\end_inset

8 is up to date and currently maintained by Uwe Stöhr.
 It certainly needs a rewrite and update.
 For example many info in chapter
\begin_inset space ~
\end_inset

2 and 3 are already covered by the UserGuide and/or the EmbeddedObjects
 manual.
\end_layout

\begin_layout Description
Customization.lyx this manual covers information how to customize \SpecialChar LyX
 for certain
 output formats, operating systems, languages etc.
 It is currently completely out of date and needs a major rewrite and update.
 If you do this please assure that your information are given for all OSes
 and \SpecialChar LaTeX
 distributions (meaning be as objective as possible).
