Since \output_changes is written again at the original position, we need to
fix those files that have been updated using the intermediate version.
The update was done by running development/tools/updatedocs.py <lyxexe> where
<lyxexe> was the path to an up to date LyX binary. All files that did contain
additional changes were reverted:
lib/doc/LFUNs.lyx
lib/doc/UserGuide.lyx
lib/doc/Shortcuts.lyx
lib/examples/de/beamer.lyx
The \SpecialChar changes are fine, these files have never been saved by LyX
after the update to 483.
Pdflatex is the recommended export tool for the manuals.
Pdflatex brings the best results for hyperlinking.
Some features (e.g. rotated text) are not available in DVI or PS (dvips).
This does not affect export from command line or autotests
(where this setting is ignored and the format must aways be given explicitely).
We do not update the local layout of our .lyx files 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 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 convert layouts to older layout formats.
These were fixed manually. I tried to add an option to updatedocs.py to
open and save a file with LyX, but that did not work, since
lyx -x 'command-sequence buffer-write ; lyx-quit' does not write and does
not quit.
Each way might be preferred by a different developer and the more
ways that can be described of running the tests, the higher the
chance is that developers will find a way that works well for them.
Explain why the export tests are enabled for formats that are not
expected to work well with certain document classes, modules, or
packages. The reason is that if a .lyx file goes from compiling
successfully for one format (even if that format is not officially
supported for the combination of features used), if that document
suddenly fails to compile, there is a significant chance that a bug
was introduced in LyX. In other words, there is a high signal/noise
ratio. If it is determined that a test is failing because an
expected incompatibility is exposed, then the test can be inverted.
The export tests, check_load tests, and URL tests are now documented
in the Development.lyx file. The export tests are described in
detail, such as how to run them and how to interpret the results.
Since Kornel's commit at e2d41970, it is now possible to update the
tex2lyx tests with CMake. Note that this is a case where a make
target in the build directory can affect the source directory, which
might not be advisable.
Writing these policies down makes it easier for newcommers to
understand guidelines and the intuition behind them.
The two policies this commit adds were responses by Georg and Richard
to two threads on the mailing list. The policies are titled
"When to set a fixed milestone" and
"Can we add rc entries in stable branch?".
