runtime(syntax-tests): Allow for folded and wrapped lines in syntax test files Commit: https://github.com/vim/vim/commit/8418446644e379a01d991dea1a70cbf69597a390 Author: Aliaksei Budavei <0x000c70@gmail.com> Date: Tue May 21 01:10:26 2024 +0300 runtime(syntax-tests): Allow for folded and wrapped lines in syntax test files The current implementation falls short for syntax test files on two accounts: 1. With folded lines -- some lines before folded lines are unnecessarily repeated in generated dump files because closed folded lines are always treated as opened for the cursor to move _in_ instead of to move _over_ them. 2. With wrapped lines (longer than 75 columns) -- some lines are omitted in generated dump files because calculations for the cursor progress and its movement commands only refer to file lines and not their layout within a 20x75 buffer (less &cmdheight). As an alternative, we abandon deterministic (and inaccurate at times) calculations for the cursor progress and, instead, advance the cursor by as much as before for a single dump file, but now rely on marking the last visible line and additional movement to position lines at desired offsets, carefully preserving compatibility for the &scrolloff and &ruler values inherited from defaults.vim. The parent Vim process will keep track of progress through a syntax test file made by its child process ("terminal") by reading the rightmost end of the ruler line from the terminal buffer, looking for " All " or " Bot " for its cue to finish dump file generation. With these changes applied, the lossless line length limit will be raised from 75 to 1425 (for a 19x75 view) columns. Also, prefer "lastline" to "truncate" for &display; hiding the content of any last _long_ line in a view goes against the purpose of syntax file testing -- all lines should be recorded. related: #15150 fixes: #14245 Signed-off-by: Aliaksei Budavei <0x000c70@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
