| 23:49 | Fix a potential division by zero. Harmless in practice but still UB so we might as well fix it. (check-in: bf026695a0 user: drh tags: trunk) | |
| 19:36 | Comment improvements. No changes to executable code. (check-in: 6f3e2f6141 user: drh tags: trunk) | |
| 19:25 | The starting and ending objects of a line are remembered and used by the "chop" feature so that the line is chopped by the correct object in the case where two or more objects have the same center. Forum post 1d46e3a0bc (check-in: 2090a12c76 user: drh tags: trunk) | |
| 17:27 | Improve the auto-chop algorithm so that the object that does the chopping must not contain the next point along the line. This is a partial fix to the bug reported by forum post 73eea815afda0715 but more work is needed. (check-in: 6210a902d5 user: drh tags: trunk) | |
|
2021-07-12

|
2021-06-11
| ||
| 20:40 | Expanded the "Designed for the Web" bit in the differences doc, giving CSS color names and the new Unicode arrow direction token feature as examples of this focus. Previoulsy, it only talked about SVG-in-HTML. (check-in: 000a544f01 user: wyoung tags: trunk) | |
| 16:53 | Provide default values for the PACKAGE_NAME and PACKAGE_VERSION macros if they are not provided on the command line. (check-in: 2cd4029e14 user: drh tags: trunk) | |

| 15:29 | Accept unicode arrow characters and/or HTML entity names as substitute spellings for the arrow tokens "<-", "->", and "<->". This avoids problems with using "<" in a pikchr script that is embedded inside of HTML. (check-in: e6916a054c user: drh tags: trunk) | |
|
2021-06-10
| ||
| 18:00 | Provide keywords "rarr", "larr" and "leftrightarrow" as alternative spellings for tokens "->", "<-", and "<->" (the names are based on HTML entity names) to make it easier to embed Pikchr source text within a larger HTML document without running into quoting issues with the "<" and ">" characters.

|
2021-02-14
| ||
| 02:15 | Add the special "this" objectname that refers to the object under construction. No documentation (yet). (check-in: 4a13f3a46e user: drh tags: trunk) | |
| 02:14 | Add a test case for the "this" objectname. (Closed-Leaf check-in: b7966b5bfb user: drh tags: this-keyword) | |
| 00:32 | Accept the object name "this" referring to the object under construction. See forum post 48cec7c89e for an explanation of why this might be useful. I'm still somewhat dubious, since not all attributes of "this" are necessarily defined at the point when it is invoked. Need to thing about this. (check-in: 3542e32d0b user: drh tags: this-keyword) | |
| 00:11 | Use darkmode rather than ardoise as the example dark-mode skin. (check-in: 94bfff470d user: drh tags: trunk) | |

|
2021-01-31

|
2021-01-23
| ||
| 20:20 | Add a section on containers to the user manual, and also a conclusion. (check-in: d0943cba6c user: drh tags: trunk) | |

|
2020-12-04
| ||
| 21:08 | Improved support for the "piktcl" TCL extension (check-in: e4b70f0e6f user: drh tags: trunk) | |

| 20:27 | Extended Makefile with target `piktcl`. This target builds a Tcl package from the library. Fixed the missing `Tcl_PkgProvide()` call in the relevant initializer function. (check-in: c85d8111c2 user: aku tags: piktcl-package-build-fix) | |
|
2020-11-28

| 01:15 | Mention the fact that text annotations on cylinders are offset from the exact center of the cylinder. (check-in: f8b70e9bd1 user: drh tags: trunk) | |
|
2020-11-20
| ||
| 18:50 | Further improvements to text layout and "fit" with cylinder objects. (check-in: cca4fea4cf user: drh tags: trunk) | |
| 17:56 | Do not put the text label of a cylinder directly in the geometric center of the object, but rather shift it downward by 75% of the radius, as that makes the text appear to be more centered and have a more pleasing appearance. See forum post d623f2faa4. (check-in: d81581d8c8 user: drh tags: trunk) | |

| 13:45 | Add initial documentation for the "fgcolor" variable. (check-in: 465cf73aa0 user: drh tags: trunk) | |
|
2020-11-10
| ||
| 14:12 | If the "fgcolor" variable is set to a valid color, then convert all black foreground text into that color before and instead of implementing dark-mode color translation. This permits an application to add a line like "fgcolor=COLOR;" to the beginning of every Pikchr script in order to implement an alternative foreground color that works regardless of the dark-mode setting. (check-in: 4b36d1278e user: drh tags: trunk) | |
|
2020-11-09
| ||
| 20:44 | Improvements to dark-mode color inversion. (check-in: 5d1dfa831f user: drh tags: trunk) | |

|
2020-10-29
| ||

| 22:28 | More improvement to userman.md: mostly spelling and grammar, but also added a few examples and documented "solid" for the first time. (check-in: 1bf8d9ee3d user: wyoung tags: trunk) | |
| 22:10 |
Updated the old "140 HTML colors" we map to RGB values to cover the
current standards thru CSS Color Module 4. Basically, this adds seven
new "grey" variants for the "gray"s we previously had plus the honorary
"Rebecca purple": https://en.wikipedia.org/wiki/Shades_of_purple#Rebecca_purple
This commit also fixes some capitalization in colors where compound nouns were "spelled" as two words with an intercap: honeydew, firebrick, cornflower, goldenrod, etc. These are single words, so they should not have the intercap. (check-in: b738db71f1 user: wyoung tags: trunk) | |
| 21:29 | Clarify where text annotations are located for a multi-segment line or arrow. (check-in: e5c7a219be user: drh tags: trunk) | |
| 21:16 | Updated test71.pikchr with the improved version as published in the PiDP-8/I project's HACKERS.md file. (check-in: 1315f822fe user: wyoung tags: trunk) | |
| 21:08 | Assorted improvements to userman, mainly grammar, but some semantic improvement, as with the "anchor" term. (check-in: 427b07ef5f user: wyoung tags: trunk) | |

| 12:42 | Add Warren's flowchart as a test case. (check-in: 519c643ddf user: drh tags: trunk) | |
| 12:31 | Add the "Purpose and Scope" document. (check-in: 35f6eff153 user: drh tags: trunk) | |
| 01:45 | The "close" attribute uses the default fill color. (check-in: 05abb6ccce user: drh tags: trunk) | |
| 01:30 | Fix the "close" attribute on lines so that it works even if the line radius is non-zero. (check-in: 727a6a56a3 user: drh tags: trunk) | |
|

| 01:31 | Rename all of the test files from ".txt" to ".pikchr" so that they can be viewed on-line in Fossil. (check-in: cfcc451af8 user: drh tags: trunk) | |
|
2020-10-10
| ||
| 22:33 | The documentation is now complete enough that we can take off the "under development" banner. (check-in: 1001eda7d2 user: drh tags: trunk) | |

| 08:28 | Applied [1278cb9154] to pikchr.y (was previously only applied to the generated pikchr.c). Also a thoroughly pedantic main() result code portability tweak. (check-in: 083f9c9bfd user: stephan tags: trunk) | |
| 05:31 | Increase the maximum token size to 50,000 bytes. (check-in: 1278cb9154 user: drh tags: trunk) | |
|
2020-10-06
| ||
| 20:05 | If the PIKCHR_PLAINTEXT_ERRORS flag is set, then render error messages as text/plain instead of as text/html. (check-in: 893ad17472 user: drh tags: trunk) | |
| 11:37 | The "pikchr" command-line tool returns non-zero following any error. (check-in: e13cade368 user: drh tags: trunk) | |

| 16:45 | Refactor internal names for consistent usage of "Statement" of "Object" and avoiding the PIC-term of "Element". "Statement" means a unit of the input text. "Object" means a graphics object. There should be no changes in behavior or in the public interface. (check-in: 3067d5c115 user: drh tags: trunk) | |

If you also set "color=LightGray" this can be an very useful aid in keeping track of the main labels of a complex diagram. (check-in: 36476557fe user: drh tags: trunk) | |
