| 22:04 | #if'd out the '.nonce' and '.check' commends in WASM builds. (check-in: 326f79ea54 user: stephan tags: trunk) | |
| 21:56 | #if'd out the the '.cd' and '.clone' commands for WASM builds. (check-in: fa391868dd user: stephan tags: trunk) | |
| 18:14 | fiddle: consolidated two duplicate CSS rules. Internal doc typo fix. (check-in: d3175a793f user: stephan tags: trunk) | |
| 17:47 | Added a disclaimer about fiddle's experimental and subject-to-change/removal nature. (check-in: 75b4f57408 user: stephan tags: trunk) | |
| 16:59 | Merge the changes to support the "fiddle" extension. (check-in: 58585f01aa user: drh tags: trunk) | |
| 16:49 | When building fiddle from its own directory (e.g. from emacs instead of the normal build process), force -O0 the sake of compilation speed. The top-level build now defaults to -Oz, which is more appropriate for that case. (Closed-Leaf check-in: 56b82ae806 user: stephan tags: fiddle) | |
| 16:42 | Tweaks to the fiddle make target so that it builds with all of the same extensions as the standard CLI. (check-in: d46a6cb974 user: drh tags: fiddle) | |
| 16:30 | Added a toggle to swap input/output field positions and simplified setup of checkboxes which toggle a CSS class on a given element. (check-in: eae3ab10c8 user: stephan tags: fiddle) | |
| 16:11 | Default to top/bottom layout with input on the bottom. Offer a toggle to swap input/output positions. (check-in: 362d236aca user: stephan tags: fiddle) | |
| 15:58 | Numerous layout tweaks, the most significant being that the layout now adapts to the window size. Swapped positions of the input/output areas. This version supports, by uncommenting a few bits, a jquery.terminal-based view but alternatives to that 300kb dependency are still under investigation. (check-in: 1aad3642c9 user: stephan tags: fiddle) | |
| 10:58 | fiddle make target now accepts fiddle_cflags=... from the CLI to overrid -Ox and such for one-off builds. (check-in: 4609a4f862 user: stephan tags: fiddle) | |
| 10:38 | Ensure that the output area is cleared of any init-time messages which the emscripten bootstrapping process emits when downloading of the wasm module is slow. (check-in: 1d8d059357 user: stephan tags: fiddle) | |
| 10:24 | #if'd out the '.log' command in WASM builds. Cleaned up the user-visible parts of the WASM module initialization. (check-in: b5fa12f824 user: stephan tags: fiddle) | |
| 09:55 | Split the fiddle JS code into separate pre-/post-init files to simplify editing. emcc will combine these into the final fiddle.js, so the number of output deliverables does not change. (check-in: d3d8ea0118 user: stephan tags: fiddle) | |
| 09:22 | Added an option to auto-clear the output area before submitting the input. Experimentally inverted the colors in the input/output areas. (check-in: 1a1e4e7fdb user: stephan tags: fiddle) | |
| 01:12 | Replaced the toggle for the notes/caveats section of the fiddle UI with a button to remove that section. (check-in: 6661d60527 user: stephan tags: fiddle) | |
| 00:38 | #if'd out the '.import' command in WASM builds. Several minor cosmetic UI tweaks. (check-in: e4f87eb7c3 user: stephan tags: fiddle) | |

| 23:40 | #if out the '.load' command in WASM builds. Several UI layout tweaks. (check-in: 67d98297f0 user: stephan tags: fiddle) | |
| 22:58 | In wasm builds, ifdef out shell commands which require file I/O, pipes, or which trigger an exit() (.quit and .exit). Documented some of the quirks and limitations of the C/WASM crossover. Keep the JS code from calling into the C code after an exit() has been triggered. (check-in: bee436e62a user: stephan tags: fiddle) | |
| 21:18 | Improved handling/reporting of conditions which trigger an exit() from native code, e.g. calling the '.read' command. Added a Help button which simply submits the '.help' command. Added commented-out variants of various -Ox flags to simplify experimenting with them. (check-in: bf06ddf412 user: stephan tags: fiddle) | |
| 20:44 | Experimental code to provide a SIZE_HINT when writing the -wal file. (Leaf check-in: 3b29080dbf user: drh tags: wal-size-hint) | |
| 18:10 | Code style fixes: s/char const/const char/. (check-in: 9bf042b2eb user: stephan tags: fiddle) | |
| 17:40 | The fiddle input/output areas now stretch and shrink as needed to account for their available space. (check-in: 4eec05457f user: stephan tags: fiddle) | |
| 17:22 | Increased default size of the fiddle output area, changed the .nullvalue default in the input area, and minor CSS tweaks. (check-in: 281aaae731 user: stephan tags: fiddle) | |
| 17:14 | Initial version of an sqlfiddle-style application using a WASM build of the sqlite3 shell. (check-in: af9c21c9e0 user: stephan tags: fiddle) | |
