v1.3

It's been a productive 3 months since v1.2. The largest effort in this release was a commands/options reworking, which will hopefully pay dividends in the future. Many other so-called improvements were made as well. Here's a list of most of them:

commands

  • All commands were thoughtfully renamed, and the command longnames should be largely stable now.
  • commands.tsv is an exhaustive list of commands and their attributes and side effects.
  • The manpage has moved to Ctrl+H, which should be its final resting place.
    • F1 will still open the manpage if the terminal doesn't intercept it.
    • but z? has been repurposed (see below).
    • Note that because iTerm reports Ctrl+H as Backspace, these help commands are also available by using Backspace (backspace for help, a new trend).
  • z Ctrl+H opens a list of commands available on this sheet.
  • Keybindings and longnames are separated out. The cmdlog now records longnames as well.
  • See the new keyboard layouts page (thanks to @deinspanjer for inspiration).

changes to existing commands and options

  • The experimental menu system (was Space) has been removed.
  • Now Space (exec-longname) executes the command for the input longname (tab completion of available commands is supported). (This function was previously bound to Ctrl+A).
  • options.wrap (for TextSheet wrapping of lines) now defaults to False.
  • R (random-sheet) opens a new sheet instead of selecting random rows (reverting to former behavior).
  • za (addcol-empty) asks for column name
  • zd (delete-cell) moves value to clipboard ("cut", like other delete commands)

options

  • options can now be set on specific sheet types or even individual sheets. Shift+O opens options for the current sheet type, and g Shift+O opens the global options sheet.
  • See available colors by pressing Space and then typing the longname colors.

new safety options

  • Error messages are sorted before informational status messages, and colored by color_error and color_warning (thanks to @jsvine for suggestion)
  • options.quitguard (default False to keep old behavior) if True, will confirm before quitting last sheet.
  • The sheets-graveyard (gS) command opens a sheet that shows all discarded (but "precious") sheets. These are stored as weak references so they will be garbage collected eventually, but can be resurrected from the graveyard sheet until then.
  • options.safety_first (default False) makes loading/saving more robust, likely at the cost of performance which can become significant in large files.
    • Currently, only removes NULs from csv input.
  • options.tsv_safe_char is split into tsv_safe_newline and tsv_safe_tab.

new power features

  • z; (addcol-sh) adds new columns for stdout/stderr of a bash command, which uses $colname to substitute values from other columns (whole arguments only, so far).
  • z| (select-expr) and z\ (unselect-expr) select/unselect by Python expression (thanks to @jsvine for suggestion).
  • z/ (search-expr) and z? (searchr-expr) to search forward/backward by Python expression.
  • gI (describe-all) describes all columns in all sheeets (like gC (columns-all)).

nice things

  • The g(, z(, and gz( variants of ( ('expand-column') are filled out.
  • z# sets type of current column to len.

new loaders

minor changes

  • System clipboard command detection is more portable (thanks to @chocolateboy for the PR).
  • date supports adding a number of days (or like foo+6*hours, foo+9*months, etc).
  • Hidden columns are darkened on columns sheet.
  • Exceptions are rolled up properly.
  • options.motd_url now uses https by default (thanks to @jsvine for the warning).
  • [DirSheet] mode is editable (set to octal like 0o0644).
  • [internal dev] ProfileSheet is improved.

known issues

  • cmdlog replay with a Ctrl+S (save-sheet) to an existing file gets stuck in an infinite loop when options.confirm_overwrite is on.
  • After renaming a file on a DirSheet, Ctrl+R (reload-sheet) is required to refresh the ext column for that row.
  • n/N (next-search/prev-search) won't continue a previous search-expr and searchr-expr.
  • show-aggregate with mean errors on int columns.
  • Contracting (with )) a previously expanded column on a dup-ed (with ") sheet results it in disappearing on the source sheet.

Thanks to everyone who contributed to this release! As always, feedback and suggestions are welcome and appreciated.
