199 When you are working on a new feature you may ask yourself whether it needs
200 an update of the .lyx file format number.
201 Whether an update is needed or not is not always obvious.
202 Below you can find a list of reasons for file format updates with explanations:

288 The reason for this is that there is no true ERT inset for math formulas:
289 Each command is parsed, and if a user happens to defne a local command
290 with the same name as a command that triggers an automatic load of a package,
291 he needs to be able to switch off the automatic loading of that package.

321 Once you came to the conclusion that a file format update is needed you
322 should use the following procedure to perform the update:

402 Add a conversion routine if needed (e.
403 \begin_inset space \thinspace{}
407 \begin_inset space \space{}
410 a new header setting always needs a conversion that adds the new setting,
411 a new document language does not need one).
412 Add a reversion routine if needed.
413 While the conversion routine is required to produce a document that is
414 equivalent to the old version, the requirements of the reversion are not
416 If possible, try to produce a proper reversion, using ERT if needed, but
417 for some features this might be too complicated.
418 In this case, the minimum requirement of the reversion routine is that
419 it produces a valid document which can be read by an older \SpecialChar LyX
421 If absolutely needed, even data loss is allowed for the reversion.
424 \begin_layout Enumerate
425 Since tex2lyx has several implicit file format dependencies caused by sharing
426 code with \SpecialChar LyX
427 , updating the file format of .lyx files produced by tex2lyx at
428 the same time as updating the main .lyx file format is strongly recommended.
429 Therefore, a compiler warning will be issued if the \SpecialChar LyX
430 and tex2lyx .lyx file
431 format numbers differ.
432 In many cases the tex2lyx update requires only the first and last item

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

476 If you did not implement full tex2lyx support of the new feature, add a

481 \begin_layout Plain Layout
487 describing the missing bits.
488 Note that it is perfectly fine if you do not add full tex2lyx support for
489 a new feature: The updating recommendation above is only issued for the
490 syntax of the produced .lyx file.
491 It is no problem if some features supported by \SpecialChar LyX
492 are still output as ERT
493 by tex2lyx, since the problems in the past that resulted in the update
494 recommendation were related to mixed version syntax, not ERT.
497 \begin_layout Enumerate
498 It would be nice if you could create a .lyx test file which contains instances
499 of all changed or added features.
500 This could then be used to test lyx2lyx and tex2lyx.
501 Unfortunately it has not yet been decided how to collect such examples,
502 so please ask on the development list if you want to create one.

695 Backporting new styles to the stable version
698 \begin_layout Standard
699 Starting with the stable \SpecialChar LyX
700 2.1 branch, there is a mechanism in place to backport
701 new styles to the stable version without the need to update the file format.
702 The basic idea is that the new style definition is automatically copied
703 to the document preamble, so that it can even be used by older minor revisions
704 that did not yet include the style.
705 To backport a new style to the stable version, the following steps are

1335 touching the encoding code or package handling code that you expect will
1336 change the exported LaTeX in some way), consider running all of the export
1337 tests before and after your change.
1338 If there are differences, please reconcile these (i.e.
1339 fix the bug or fix the tests)
1344 Ask for help if you're not sure what to do or if you do not want to run
1345 the tests, post the patch on the list and others will run the tests.

1412 To run all tests, in the build directory simply run the command
1413 \begin_inset Flex Code
1416 \begin_layout Plain Layout
1423 To run only some of the tests, use the command
1424 \begin_inset Flex Code
1427 \begin_layout Plain Layout
1434 \begin_inset Flex Code
1437 \begin_layout Plain Layout
1443 is a regular expression that matches test names.
1444 To run only the export tests, you can use

1476 It is often useful to list the tests without running them (e.g.
1477 if you want to know how many tests there are or whether your
1478 \begin_inset Flex Code
1481 \begin_layout Plain Layout
1487 regular expression did what you expected).
1488 This can be done with the

1545 However, when running the tests in parallel, sometimes tests fail that
1546 pass when run sequentially.
1547 A reasonable approach is to first run the tests in parallel and then run
1548 the failed tests sequentially.
1549 For example, to run 8 jobs at a time:

1611 There have been bugs in LyX and in LaTeX which cause compilation to hang,
1612 and without a timeout a test might never stop (in one case there was even
1614 If a test times out, the
1615 \begin_inset Flex Code
1618 \begin_layout Plain Layout

1659 Interpreting the export test results
1662 \begin_layout Standard
1663 A test can fail for several reasons, not all of them bad.
1666 \begin_layout Enumerate
1667 The .lyx file could have been added recently and some formats are not expected
1671 \begin_layout Enumerate
1672 A dependency is not met (e.g.
1673 the LaTeX class file).
1674 One hint that this is the case is that the corresponding
1675 \begin_inset Flex Code
1678 \begin_layout Plain Layout
1684 test will likely also fail.
1687 \begin_layout Enumerate
1688 An inverted test fails to fail (i.e.
1689 export that previously failed now works).
1692 \begin_layout Enumerate
1693 An external dependency was updated (e.g.
1697 \begin_layout Enumerate
1698 A recent code change introduced a bug.
1701 \begin_layout Enumerate
1702 \begin_inset CommandInset label
1708 A change in a document exposed a previously unknown bug or an incompatibility
1709 with an export format (e.g.
1713 \begin_layout Standard
1714 Because the .lyx files are exported in several formats, it is not surprising
1715 that many of the exports fail.
1716 This expectation of failure is addressed by
1717 \begin_inset Quotes eld
1721 \begin_inset Quotes erd
1724 the tests, that is, by marking the test as
1725 \begin_inset Quotes eld
1729 \begin_inset Quotes erd
1732 if the export exits with error and as
1733 \begin_inset Quotes eld
1737 \begin_inset Quotes erd
1740 if the export succeeds
1745 It follows that these expected failures will not show up as failed tests
1746 in the test results and thus will not pollute the
1747 \begin_inset Quotes eld
1751 \begin_inset Quotes erd
1755 If the export actually succeeds, then the test will fail.
1756 The purpose of this failure is to get your attention—something has changed,
1757 possibly for the better.
1760 \begin_layout Standard
1761 We try to document why a test is inverted or ignored.
1762 See the comment (prefixed with
1763 \begin_inset Flex Code
1766 \begin_layout Plain Layout
1772 ) above the block in which the test is listed as inverted or ignored in
1774 \begin_inset Flex Code
1777 \begin_layout Plain Layout
1778 development/autotests/revertedTests
1784 \begin_inset Flex Code
1787 \begin_layout Plain Layout
1788 development/autotests/ignoredTests
1794 It is possible that an export goes from succeeding to failing just because
1795 the document was changed and the document was never expected to work with
1796 a certain export format in the first case.
1797 Once this is confirmed to be the situation, the test can be inverted.
1800 \begin_layout Standard
1801 A good question is why do we enable the tests for non-default formats? The
1802 answer is that if a non-default route is broken it is often because a bug
1803 was introduced in LyX and not because a document-specific change was made
1804 that is not supported by the route.
1805 In other words, there is a high signal/noise ratio in the export tests
1806 for some non-default formats.
1810 \begin_layout Standard
1811 What action should you take if a test fails? First, check manually that
1812 when the compilation succeeded before the resulting PDF was good.
1813 In fact, sometimes it is an improvement when a test fails.
1814 If you check manually, it might be the case that the export was succeeding
1815 before but showing garbled text in a PDF output.
1816 Now it might fail with a clear message of "language xyz not supported".
1817 It is always good to check manually why something fails and if it passes
1818 if the PDF output is good.
1821 \begin_layout Standard
1822 Sometimes a test is fixed as side-effect of some change.
1823 We should uninvert a test (remove it from the
1824 \begin_inset Flex Code
1827 \begin_layout Plain Layout
1833 file) in order to preserve the fix.
1836 \begin_layout Standard
1837 When a test or several tests fail, consider checking the files in the
1838 \begin_inset Flex Code
1841 \begin_layout Plain Layout
1847 subdirectory of your build directory.
1848 In this subdirectory are three files: the file
1849 \begin_inset Flex Code
1852 \begin_layout Plain Layout
1858 simply lists the tests that failed on your last
1859 \begin_inset Flex Code
1862 \begin_layout Plain Layout
1869 \begin_inset Flex Code
1872 \begin_layout Plain Layout
1878 file contains the output from the tests (and often has details explaining
1879 why a test failed); and the
1880 \begin_inset Flex Code
1883 \begin_layout Plain Layout
1889 file lists the times that it took to run the tests.

2898 These tests check whether a .lyx file loads without any terminal messages.
2899 They correspond to the manual operations of simply opening a .lyx file on
2900 the terminal, exiting LyX once the file is loaded, and then checking whether
2901 there is any output from the terminal.
2902 These tests are useful for catching malformed .lyx files and parsing bugs.
2903 They can also be used to find a .lyx file in which an instance of something
2905 To do this, compile LyX with a local patch that outputs something to the
2906 terminal when an instance is found, and then run the check_load tests to
2907 see if any fail, which would mean that the situation occurs in the LyX
2908 documentation files corresponding to the failed tests.
2909 These tests are expectedly fragile: any LyX diagnostic message, which is
2910 not necessarily an error, would cause the tests to fail.
2911 Similarly, any message output by a library (e.g.
2912 Qt) would also cause failure.
2913 There are some messages that the check_load tests are instructed to ignore,
2914 which are stored in the file

3113 splash.lyx it is the first file you see after an installation.
3114 We assume that a new user sees this.
3115 It is therefore designed to be as simple as possible.
3116 Therefore please don't add any new formatting, only fix typos etc.
3117 Splash.lyx is up to date for \SpecialChar LyX
3118 2.1.x, currently maintained by Uwe Stöhr.
3121 \begin_layout Description
3122 Intro.lyx This is the manual new users will read to learn \SpecialChar LyX
3124 It therefore uses a limited set of formatting.
3125 For example a standard document class.

3134 Tutorial.lyx our tutorial.
3135 It must be always up to date.
3136 Normally there is nothing to add since we don't want to overwhelm new users
3137 with too much details.
3138 The will learn these details while using \SpecialChar LyX
3139 and we have special manuals.

3207 rules in editing the docs:
3210 \begin_layout Enumerate
3211 If you are not the maintainer of a doc file or a chapter/section, you MUST
3212 use change tracking so that the maintainer could review your changes
3215 \begin_layout Enumerate
3216 Respect the formatting of the document.
3217 The different files use different formatting styles.
3218 That is OK and has historic reasons nobody fully know ;-).
3219 But it is important to be consistent within one file.
3222 \begin_layout Enumerate
3223 All changes you make to a file in one language MUST also go the file in
3224 the other actively maintained languages.
3225 Normally the maintainer does this for you, if you are the maintainer, you
3226 must do this by copying or changing the changed or added text to the other
3227 files so that the translators sees the blue underlined text and know what
3228 they have to translate and what was changed.
3231 \begin_layout Enumerate
3232 You MUST assure that the document is compilable as
