2024-02-08
20:41		[b94fdea4a8] part of check-in [ad1f8186cd] Fix the autofit functionality for the diamond object. New test cases for the same. (check-in: [ad1f8186cd] user: drh branch: trunk, size: 175808)

2023-08-12
19:20		[c4e71ab8e0] part of check-in [62b766efe8] It seems like the "same" operator should not mess with layout direction. See forum thread 75a2220c44. (check-in: [62b766efe8] user: drh branch: trunk, size: 173317)
2023-05-18
16:57		[2444a733e5] part of check-in [03664a38cf] Remove the artificial enlargement of "mono" text, as that seems not to be necessary when the output is rendered by Fossil. Must be some kind of CSS issue. (check-in: [03664a38cf] user: drh branch: trunk, size: 173381)
14:10		[859d9322d2] part of check-in [22e2a2c622] Adjust the font size and text length computations for monospace. (check-in: [22e2a2c622] user: drh branch: monospace, size: 173410)

2022-12-07
11:14		[64b6310fe1] part of check-in [21ca6b843d] Avoid unnecessary rounding of coordinates in the generated SVG. Forum post b571590af6. (check-in: [21ca6b843d] user: drh branch: trunk, size: 172754)
2022-07-28
14:40		[90bcc7df74] part of check-in [ca92b3a952] Allow any value for HEADING. Convert it to -360..360 before use. Forum post 56140a59018db001 (check-in: [ca92b3a952] user: drh branch: trunk, size: 172849)
2022-06-20
06:51		[7e75b99f3a] part of check-in [d9ee756594] Help text typo fix and added a mention that all output goes to stdout, as suggested in [e3a1e165ab799e64]. No code changes. (check-in: [d9ee756594] user: stephan branch: trunk, size: 172944)
2022-06-14
17:41		[8d9940660d] part of check-in [a28bee7108] Expanded [43eb7d998415] to permit digits in HTML entities after the first character, to allow for sup2, frac12, and similar entities. Reported in [dcf1418ef16f]. (check-in: [a28bee7108] user: stephan branch: trunk, size: 172909)
15:25		[f9c4770946] part of check-in [b5a5779c8d] Minor doc correction and code style tweak to the previous checkin. No functional changes. (check-in: [b5a5779c8d] user: stephan branch: trunk, size: 172755)
14:32		[44574668b3] part of check-in [43eb7d9984] When outputing HTML-escaped text and an ampersand is encountered, only transform it to an HTML entity if it looks like it's not one already. HTML entities are left as is, noting that we do only a syntactic check and not a test for whether the entity is a standard/known one. This replaces [aca3d2dc1a00], reverting the doc changes made by that checkin. (check-in: [43eb7d9984] user: stephan branch: trunk, size: 172751)
09:33		[231f59b035] part of check-in [aca3d2dc1a] Replaced ampersand-deg-semicolon escape sequences in pikchr string literals in various docs with a degree symbol to work around that escape sequence having been broken by [641b4ff2e552183c]. Extended the comment about ampersand escaping in pik_append_text(). No code changes. (check-in: [aca3d2dc1a] user: stephan branch: mistake, size: 171965)
2022-04-25
01:28		[d883500e56] part of check-in [3d15c0920a] Correctly adjust the bounding box when the size of a circle is set using "diameter". Fix for ticket [4449371aa4d8ed2b]. (check-in: [3d15c0920a] user: drh branch: trunk, size: 171837)
2022-04-05
14:39		[56f4c006f8] part of check-in [221988914e] Limit the number of tokens that can be processed in a single script to avoid an exponential macro-expansion attack, such as described by forum thread 6b9b95de35. (check-in: [221988914e] user: drh branch: trunk, size: 171816)
2022-03-28

2021-12-24
04:09		[9e499084a3] part of check-in [641b4ff2e5] Escape ampersands when emitting text nodes, per report in forum post 37584617be. (check-in: [641b4ff2e5] user: stephan branch: trunk, size: 171393)
2021-11-04
18:36		[b18e6e4735] part of check-in [b79ce27929] Fix a compiler warning: decimal constant is unsigned only in ISO C90" (check-in: [b79ce27929] user: drh branch: trunk, size: 171391)
2021-07-17
23:49		[b93ac06ffc] part of check-in [bf026695a0] Fix a potential division by zero. Harmless in practice but still UB so we might as well fix it. (check-in: [bf026695a0] user: drh branch: trunk, size: 171387)
19:36		[1fe07fff1c] part of check-in [6f3e2f6141] Comment improvements. No changes to executable code. (check-in: [6f3e2f6141] user: drh branch: trunk, size: 171376)
19:25		[9a9b855fec] part of check-in [2090a12c76] 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 branch: trunk, size: 171235)
17:27		[37ead8097d] part of check-in [6210a902d5] 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 branch: trunk, size: 170051)
2021-07-12
16:51		[31463fed31] part of check-in [cf12e257ba] Makefile for MSVC. Fix the pik_round() routine so that it works with MSVC. (check-in: [cf12e257ba] user: drh branch: trunk, size: 169529)
16:24		[1ce6573a74] part of check-in [340e69b9fc] Convert NaN into 0 for floating-point to integer conversion, to avoid harmless UBSAN warnings. (check-in: [340e69b9fc] user: drh branch: trunk, size: 169530)
2021-07-09
16:53		[b6620d2321] part of check-in [f528c80c14] Improved fuzzing. Reduce fuzzer warnings by adding pik_round() to do floating-point to integer conversion in a well-defined way. (check-in: [f528c80c14] user: drh branch: trunk, size: 169503)
16:41		[dcb54e78c0] part of check-in [62c4c4a65a] Avoid unnecessary calls to realloc() by correctly remembering the size of the output buffer from the previous allocation. (check-in: [62c4c4a65a] user: drh branch: trunk, size: 169280)
2021-07-08
19:22		[d22e54bf6e] part of check-in [99d536494d] Fix a possible NULL pointer dereference that became possible due to the "this" enhancement of check-in [4a13f3a46ed297a6]. (check-in: [99d536494d] user: drh branch: trunk, size: 169277)
18:59		[67253efbcb] part of check-in [4271de68b6] Use a seperate routine to convert floating point values to integers that does proper truncation of the value if the input is out of range, in order to avoid (harmless) UBSAN warnings. (check-in: [4271de68b6] user: drh branch: trunk, size: 169225)
2021-06-11
16:53		[fd6a5a9fa0] part of check-in [2cd4029e14] 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 branch: trunk, size: 168966)
15:29		[7e668476a5] part of check-in [e6916a054c] 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 branch: trunk, size: 168845)
2021-06-10
18:00		[717fbb3595] part of check-in [1e359f8ed5] 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. (check-in: [1e359f8ed5] user: drh branch: html-defense, size: 167655)
2021-02-14
00:32		[208f853bad] part of check-in [3542e32d0b] 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 branch: this-keyword, size: 167478)
2021-02-02
01:54		[b6d6c2e11b] part of check-in [8d39358520] Fix harmless compiler warnings. (check-in: [8d39358520] user: drh branch: trunk, size: 167363)

15:26		[83df0aefe3] part of check-in [812efbcda8] Fix rendering of cylinders with oversize radii. See forum post 983b36dbcf. (check-in: [812efbcda8] user: drh branch: trunk, size: 167038)
2021-01-29
14:16		[ae31ef54cf] part of check-in [4eaa29827e] Fix a problem with the "-" argument processing in the pikchr shell program. (check-in: [4eaa29827e] user: drh branch: trunk, size: 166960)
2021-01-25
20:18		[f52ca5f5f9] part of check-in [ac6a4549de] If the "bgcolor" variable is set, then replace any 0xffffff color value with the the value in bgcolor. (check-in: [ac6a4549de] user: drh branch: trunk, size: 166961)
2021-01-24
17:36		[f1eeb14b8b] part of check-in [b702e4b762] Enhance the command-line "pikchr" program so that if an input filename is "-" it reads standard input. (check-in: [b702e4b762] user: drh branch: trunk, size: 166604)
2020-12-04
21:07		[764bfe1c3d] part of check-in [a264ebcf89] Fix harmless compiler warning. Fix the Makefile so that it does not fail if the piktcl directory already exists. (check-in: [a264ebcf89] user: drh branch: piktcl-package-build-fix, size: 165939)
20:27		[44c39b5ce6] part of check-in [c85d8111c2] 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 branch: piktcl-package-build-fix, size: 165919)
2020-11-28
21:26		[bb91962e0b] part of check-in [b8fa9aed02] Ignore excessive (and senseless) scale factors. (check-in: [b8fa9aed02] user: drh branch: trunk, size: 165861)
2020-11-27
21:52		[3066ddd2e2] part of check-in [8bf08592ca] Minor code changes to avoid harmless compiler warnings. (check-in: [8bf08592ca] user: drh branch: trunk, size: 165811)
2020-11-20
18:50		[ced69764cd] part of check-in [cca4fea4cf] Further improvements to text layout and "fit" with cylinder objects. (check-in: [cca4fea4cf] user: drh branch: trunk, size: 165642)
17:56		[a77a733b4d] part of check-in [d81581d8c8] 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 branch: trunk, size: 165622)
2020-11-13
18:20		[aef5658746] part of check-in [2309e4b4bd] Improved handling of dark mode in cases where the foreground and background colors are the same. (check-in: [2309e4b4bd] user: drh branch: trunk, size: 165513)
2020-11-10
14:12		[fd40fd3d3d] part of check-in [4b36d1278e] 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 branch: trunk, size: 164457)
2020-11-09
20:44		[2f54fbba7f] part of check-in [5d1dfa831f] Improvements to dark-mode color inversion. (check-in: [5d1dfa831f] user: drh branch: trunk, size: 164116)

2020-10-29
22:10		[792ea8e8ff] part of check-in [b738db71f1] 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 branch: trunk, size: 163014)
13:35		[ff16e294d4] part of check-in [7364250d71] Ensure that the token length field is always initialized when processing macro errors. (check-in: [7364250d71] user: drh branch: trunk, size: 162548)
01:45		[6c0616e2eb] part of check-in [05abb6ccce] The "close" attribute uses the default fill color. (check-in: [05abb6ccce] user: drh branch: trunk, size: 162466)
01:30		[a2ecc98846] part of check-in [727a6a56a3] Fix the "close" attribute on lines so that it works even if the line radius is non-zero. (check-in: [727a6a56a3] user: drh branch: trunk, size: 162560)
2020-10-21
16:30		[3cd49bd9f4] part of check-in [ac0ee529a8] Fix harmless compiler warnings. (check-in: [ac0ee529a8] user: mistachkin branch: trunk, size: 162384)

08:28		[496b416636] part of check-in [083f9c9bfd] 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 branch: trunk, size: 160997)
2020-10-06
20:05		[b38d7d84aa] part of check-in [893ad17472] 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 branch: trunk, size: 160965)
11:37		[4098776da9] part of check-in [e13cade368] The "pikchr" command-line tool returns non-zero following any error. (check-in: [e13cade368] user: drh branch: trunk, size: 160046)
2020-10-01
19:22		[b71828b433] part of check-in [b1de53d92c] Add an optional TCL interface, enabled using the -DPIKCHR_TCL compile-time option. (check-in: [b1de53d92c] user: drh branch: trunk, size: 159965)

16:45		[9f11b94246] part of check-in [3067d5c115] 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.
