Parsing and input processing: - unify alignment, direction - find libraries (e.g., from .pro) - on parse error, politely complain, don't terminate; convert abort / assert(0) to proper error indications - quoted strings can have embedded double quotes, with \" (see parse_field) - check what happens with UTF-8 (c4puter/motherboard) Data model: - implement destructors - check for memory leaks - sheets appearing multiple times are parsed anew each time. Should we try to combine them ? - likewise, reuse sheets and libraries that are the same in the next/previous revision (according to their OID) Visualization (dwg.c and such): - glabel: build for "right" style, then rotate poly (like hlabel) - show open pins / wires - check remaining alignment / direction / rotation cases in switch statements - support mirroring (and detect-complain if unexpected) [should be done now] - pin shapes (inverted, clock, etc.) - optionally display pin type - record.c (bb_rot): implement bounding boxes for text - nesting gfx in diff is a huge kludge, caused by global vars in gfx.c Rendering: - better text size guessing also for FIG - consider switching to Hershey fonts (that's what eeschema uses, right ?) (goal: prevent font geometry from changing when scaling) - support fonts attributes ? - support line thickness ? - ~ as overline (grep for ~ in out.fig) - let user set PNG size [we have zoom level] - return indication of whether diff found any differences - in diff, pass only options understood by cairo_png - find out why in Cairo PDF non-dashed lines disappear if CAIRO_LINE_CAP_ROUND - non-interactive diff mode currently requires both sheets to have identical size - diff area algorithm will fill anything resembling a closed path, no matter how little is inside (e.g., a changed large but empty rectangle will be filled) GUI: - fonts grow beyond their bounding boxes when zooming in - dragging can be slow. maybe reusing old content and only redrawing new will help ? - highlight nets ? - we use find_corresponding_sheet way too often. Consider changing curr_sheet to new_sheet and old_sheet. - introduce location string, as command-line argument, e.g., [top-sheet/]rev-old,rev-new[,x,y[,zoom]] or maybe (allowing for sheets from completely different sources): [revA]:[topA]:[sheetA][,[revB]:[topB]:[sheetB]][@x,y[,zoom]] [revA]:[topA]:[sheetA][,[revB]:[topB]:[sheetB]][@x,y[,radius]] - set/use location string via clipboard - incremental search with / ? and maybe Ctrl-S and Ctrl-R https://www.gnu.org/software/emacs/manual/html_node/emacs/Repeat-Isearch.html#Repeat-Isearch - allow changing font size - maybe allow changing diff contrast GUI/history - should have quick way to show diff of a single commit - in history, set font to non-bold if showing details - add scrolling with keys to history - add manual selection with Up/Down/Enter - "what I am selecting" indication (color of frames of sheets in history) is not very clear. GUI/sheets: - need a way to change new/old sheet association, in case automatic selection fails (reserved hotkeys: Left/Right) GUI/glabels: - maybe indicate how many times label is used on each sheet - maybe indicate how it is used - there can be "hanging" pop-ups, by design.
