* A revision to the font, Unicode, Tedit, and other modules to implement the MCCS character coding as the standard for internal text strings. MCCS is a variant of XCCS with arrows switched with circumflex/underscore and $ switched with currency, and allows for additional code assignments over time. :MCCS replaces :XCCS as the default external format, especially for source files. The file XCCS is removed in favor of the file MCCS, which includes the XCCS external format for backward compatibility.
* This includes a single Medley-font formatted font file for each of the family/size/face display fonts. The glyph assignments correspond to the MCCS character encoding (except for fonts with idiosyncratic encodings--Hippo, Symbol). All charsets from legacy font files are included in each file, and the character sets and glyphs in each file have also been extended by offline coercion from related families (e.g. Glyphs not in legacy Terminal are taken from legacy Modern). There should be fewer black boxes, and character-display shouldn't change when you switch fonts.
* The Unicode mapping tables have been redefined to set up correspondences between Unicode and MCCS, not XCCS. Separate XCCS to/from MCCS mapping functions are provided in the file MCCS; they are no longer included in INTERPRESS.
* TEDIT converts characters in legacy fonts to their new MCCS codes as it reads formatted files, marks the file as MCCS compatible and preserves the new codes on writing.
* Default keyboard assignments produce the MCCS uparrow and leftarrow for shift-6 and shift-hyphen, use Function-6 for circumflex and Function-10 for underscore.
See documentation in FONTCODECHANGES.TEDIT MCCS.TEDIT MEDLEYFONTFORMAT.TEDIT in docs/internal, and library/UNICODE.TEDIT.
* TMAX updates for compatibility with Tedit changes
* DOC-OBJECTS changes for compatibility with Tedit changes
* MODERNIZE update for Tedit split windows
* Core Tedit files
* IMAGEOBJ: Remove dependency on Tedit internals
* WINDOW: Remove dependency on Tedit internal declaration
Still strange that WFROMDS should have to branch on Tedit
* WINDOWOBJ gets window of TTY process before the window of the stream of the TTY process
So insert into Tedit works
* TEDIT-CHAT: try to use TEXTSTREAM vs TEXTOBJ
* Fix tab-initialization problem in SLIDES.TEDIT
as reported by @nbriggs
* TEDIT-CHAT: use TSTREAM rather than TEXTOBJ
* Updates after lots more testing, particularly scrolling
Some other files dragged along to avoid dependence on Tedit internals
* Remove unwanted SAVE.SYSOUT
* Addresses more end-of-file and empty-file display issues
Try it again
* TEDIT-DEBUG tracking other changes
* Odds and ends
* Adjust EOF selection and caret-scrolling on copy
* More cleanup, plus fixing a few more ancient (Venue) glitches
As usual, the problems have to do with the funky behavior of EOL's in the middle and end of the document. More abstraction and refactoring to get better control of this (I hope).
* TEDIT-WINDOW: Scroll down of big objects
Trying to fix what happens at the transition when scrolling down brings a big-object's top down in the window. Approach is to bring down the line above, which may make for a little jump. I hope that solves it.
Scrolling up still needs some adjustment.
* Eliminate junk at top of window after up/down scrolling of big objects
BLTSHADE is OK there for scrolling, but not for redisplay after editing. In the edit case, the top of the pane above the last valid line is preserved.
Scrolling still has the problem that the window can go blank at the first scroll that brings a tall object into the pane--still working on that.
* Scrolling with tall lines should be more continuous
* Another tweak for scrolling
plus interface extension to TEDIT.MOVE and TEDIT.COPY, a little more on field menus
* More robust strategy for field menu buttons
Surround the field with prefix and suffix pieces with image objects that print the pre and post labels and shift the selection forward or backward into the field. Doesn't depend on inherited quirky logic in the selection line-scanner.
* Field selection ignores right and middle clicks
* A little more menu/selection tweaking
You can't extend through fields and buttons
* Added CUSTOMBUTTONEVENTFN to menu field buttons
Also, menu buttons in general can't be deleted
* A few more glitches, plus a little selection refactoring for buttons
* Reduce flicker in pargraph menu margin bar
* screen update glitch
* DOC-OBJECTS, TEDIT-SCREEN: Fixes the HCFILES DOC-OBJECTS failure
* TEDIT-BUTTONS: Field values should always be shown in the specified FIELDFONT
* Abstracting the structure of the history lists
cleanup, but mostly as a precursor to maybe doing a ring buffer of a specified length
* TEDIT-FILE, a little font-reading cleanup
* Include the files from rmk-39 that deal with the text/binary renamefile problem
* TEDIT-PAGE addresses #1905
* Fix BUTTONSTART to STARTPC in Put/Get menu buttons
* Use width of M as width of EOL--easy to select
Also put in function call for potential kerning--needs eventual FONT support
* Rename a few internal functions from TEDIT.-- to \TEDIT.--
* Doesn't make sense for a charlooks to not have a font
* TEDIT-BUTTONS - Fix comment
* Take out Tedit internals from \CARET.FLASH?
Should have included this in fifth round long ago
* TEDIT-FILE: use DEFAULTFONT for .sh files
Easier to follow the layout
* TEDIT-LOOKS: fix loadup order
* tedit-exports.all Remove line-has-protection field
Useless
* Make sure that charlooks change as expected
* External format for .sh files is UTF-8
* Better display of history information for debugging
* Button changes: show document font families, better fields
* TEDIT-WINDOW, remove extra truncated line with down-scroll
* TEDIT-SELECTION: suppress line/paragraph selection for built-in menus
Line/para selection would be reasonable for multi-line fields, but most menu lines have protected text that would behave inconsistently. So just suppress
* Better support for potential kerning
* Fix empty field value
* Simplify ASCII translation code
* Make sure headings have a default tab
* Word boundary at character 1
* Remember that you specified a font class instead of a font
For the charlooks menu, but also so that it is saved on a put
* More items on the Family NWAY-button line
* glitch
* TEDIT-LOOKS: Better algorithm for Ascii translation
* Charmenu remembers previous "Other" fonts, even if not installed
* Fix initial piece index
* Fix fontclass changes (again)
So SEE of a PDF file should open up a desktop window in a pdf viewer. (This uses PDFILEP, which looks inside the file, not at the extension. So it might try to open a file with a wrong extension, and the viewer might fail.)
* Update PDFSTREAM: integrate ShellOpen into PDF-SEE in place of MacOS specific calls; update how PDFCONVERTER is set to fix bug whereby it was always ps2pdf
* Fix ShellOpen so that if a file to open is versioned then that file is copied to tmp and its filename is changed from foo.pdf;25 to foo~25~.pdf and this tmp is passed to the opener instead of the original file. This is so that the extension is preserved as the last thing when there are versions. The extension as the last thing is used by most openers to determine the file type.
* Oops. Checked in the wriong versions of UNIXUTILS(.DFASL) last commit. Correcting that here.
* PDFSTREAM: first implementation
Makes PS file, then applies separate utility (if available) to convert PS to PDF
* POSTSCRIPTSTREAM: Adds extra field to postscript data for PDFSTREAM filename
* HARDCOPY: fixes printer menu
* PDFSTREAM: define PDF fonts as POSTSCRIPT fonts
* PDFSTREAM: fix convert template
* PDFSTREAM: Fix logic around closing the postscript sub-stream
* PDF Stream: slight generalization
* PDFSTREAM uses AFTERCLOSE streamprop so doesn't require change to POSTSCRIPTSTREAM
* UNIXUTILS: moved PROCESS-COMMAND and SLASHIT from GITFNS and PSEUDOHOST resp.
PROCESS-COMMAND executes a command in process-stream, like ShellCommand, but returns a completion code and not what happens in the shell. SLASHIT is an approximation (doesn't deal with versions) of converting a Medley file name to its Unix equivalent, to use in commands
* GITFNS: PROCESS-COMMAND moved to UNIXUTILS, cleanups from previous (unexamined) PR
The other PR will be cleaned out
* PSEUDOHOSTS: Moved SLASHIT to UNIXUTILS, also includes minor change in previous (unexamined) PR, to be removed
* PDFSTREAM: wrapped FULLNAME around TRUEFILENAME
* Restore POSTSCRIPTSTREAM
* UNIXUTILS: Added UNIX-FILE-NAME
Produces a Unix filename corresponding to a Medley file name (slashes, version number). For use in ShellCommand an PROCESS-COMMAND.
* PDF-STREAM: added SEE-PDF
A little stub that (on a mac) does a shell command to open Preview on the Unix-named file corresponding to a medley name
(Also added back some key functions that got lost in a bad edit)
* Pick up master changes
