        "description": "kanten\n======\n\nthe enlightened pager. less paging. more content. read widely.\n--------------------------------------------------------------\n\n...because you have more than 80 columns\n\nOrigin:\n\nkan-ten: Japanese for word for agar, a gelatinous substance derived from seaweed.\n\nA program for reading in the terminal. A pager for the early 90s?\n\nThis program was inspired by a similar one called\n[Tofu](http://amarsagoo.info/tofu/) for OS X, a column-based reader application,\nwhere the columns are arranged horizontally.  Given the aspect ratio of computer\nmonitors, I decided to create kanten to be a unix pager replacement (more and\nless) that is not limited to 80 columns.\n\nTODO\n----\n[x] horizontal progress bar indicator\n[x] figure out how many columns are displayed, and adjust pbar accordingly\n[x] max columns should always be shown\n[x] progress bar should consider all visible columns as shown \n[x] some vertical empty space at the top\n[x] space bar should move whole screen over (displayed_columns)\n[x] scroll using the mouse\n[ ] middle mouse button pastes contests of X11 paste register into a new buffer\n[ ] mouse events don't work after 'v' (entering editor)\n[ ] d and u (^D and ^U) go forward and back a column (half-screen in less)\n[x] reading from stdin\n[x] process keyboard shortcuts after reading from stdin (the way less does)\n[ ] read buffering (don't read the whole file before filling in)\n    - MUSTFIX for sane STDIN piping (e.g. git log | kanten)\n    - urwid's edit.py has an example of lazy loading\n[ ] mouse interactions broken in xterm after sleeping kanten - what gives?\n    - can't click to select text in xterm\n    - cannot select text even after sleeping kanten\n[ ] double spacing option for easier reading?\n[x] specifying a filename from commandline\n[ ] demo file that explains kanten (tutorial)\n[ ] do a full install as a python package with an entry point\n[ ] configuration in ~/.config/kanten\n[ ] all configurable take defaults from ~/.config, but overwritten by params\n[x] configurable number of columns (via -w or --width)\n[x] automatically figure out size (for height, and number of columns)\n[x] allow setting height from command line\n[x] implement :set commands\n    (:set height, :set width)\n[x] 'v' to edit the file , just like less\n    - disabled for stdin? at least if EOF not encountered\n    - wouldn't support editing stdin\n    [x] respect $EDITOR, use vim if EDITOR not set\n        [ ] would be even better if we check if vim exists, use vi otherwise\n    [ ] on exit from editing, refresh the file in kanten\n[ ] open file to the right line (at least the top-left column's line)\n    - set cursor location either via search or mouseclick\n    - mouseclick should un-highlight the current match of search (if any) and\n      highlight the whole line instead\n      - actually - it might make sense to just use widget focus infrastructure\n        for this in urwid?\n    [ ] mouse click column detection is off by the size of the margins\n        - find it from window_width % column_width / num_columns\n    [ ] drag click events for paging (flick-click right to go forward, etc)\n[ ] run_wrapper to restore previous screen?\n    - moar and bpython do this, i think\n[ ] (refactor) move all initialization into a function, to allow for re-init\n[ ] dynamic resizing of width \n    [ ] (via + and - commands, perhaps)\n    [ ] via \":set width=40\"\n[ ] respond to sigwinch and re-do the number of columns\n    - number displayed changed, so the pbar needs an update\n[x] param parsing (e.g. add --help)\n[x] hide the progress bar (ctrl-n is what zathura uses or something?)\n    [x] currently implemented via t\n[ ] add a parameter to disable progress bar\n[ ] add help dialog on h\n    - not ? - that's reverse search, but h and H and F1\n    [x] easter egg planted\n    [x] :help should work\n[x] add : command mode\n    [x] support :q\n    [x] support :f for file info\n    [ ] don't allow deletion of ':' prompt in command mode\n    [ ] backspace in command mode should leave it? (like vim\n    ( ) history (up and down arrows)\n    ( ) q: and :^F command buffer?\n[ ] (maybe) support multiple buffers?\n    - :n and :p (or :N) for next and previous\n    [ ] :e to read a different file?\n        - filename tab completion for :e\n[x] . (dot) to repeat previous command (page up or down, next, etc)\n[ ] support more less/more keys \n    [x] < and >\n    [x] z and w\n    [x] j and k (page-wise OK)\n    [x] = to show file name / info (ctrl-g should also work)\n        [x] ctrl-g should show status bar only once\n    [ ] others?\n    [ ] F - forward forever (for stdin)\n[ ] control key combos\n    [x] ctrl-v  ctrl-f  for page forward and ctrl-b for back back\n    [x] ctrl-g for file info\n[ ] (maybe) implement marking system (top lines?)\n    - like less, marks will only live for duration of program execution\n[ ] support jumping to a particular line\n    - would go along with editing a file at that line\n    - and allow us to jump back into the same line after editing?\n    - jump to the line of the currently highlighted thing\n[ ] support ctrl-i and ctrl-o location-list jumping\n[x] reflow of text\n[ ] (maybe) reading cursor (like dictator?)\n[x] 'g' to go to the beginning \n    [ ] gg g0 g$ and other commands?\n[ ] implement number prefixes\n[x] 'G' to go to the end\n[x] split boxes so that they partially fit\n[x] clip off lines that are too long even in one go\n[x] last line of text being cut-off\n[x] fix formatting (spacing) for cells which were cut\n[x] columns currently allowed to expand: don't let them \n    - boxadapter?\n    - options('given', width) ?\n    - use padding!!\n[ ] (alignment) 'the less is' line currently getting screwed up :\\\n[ ] (refactor) start off with one Padding(text) and keep splitting in\n    - don't pre-split\n    - such an approach will be a reasonable way to go with searching, anyway\n        - i.e. highlight the word in every instance, and reflow?\n        - or at least to find the location of the word, and then index into the\n          right / approximate column\n    - also makes it reasonable to scroll line by line (daisy chain visible cols)\n    - stop after all visible columns are filled\n[x] search using / (to seek around)\n    - use a footer / header of the frame widget to do this and :?\n    [x] enter do submit footer content\n    [x] esc to refocus the window\n    [ ] case insensitive search via -I command line parameter\n    [ ] incremental search via incsearch\n[x] highlight words in the text\n[x] highlight searched word (switch to ANSIText?) \n[x] highlight diff output (via 'd', disable with 'D')\n    [ ] detect diff output \n    [x] toggle it via :set ft=diff\n    [x] force diff output with -d flag\n    [x] use diff output when openining .diff and .patch files\n    [ ] handle diff lines that span multiple columns properly \n[ ] parse shell escaped characters properly\n    - so we can read man pages\n    - look at the piped output of grep --color=always\n    - I think the Qt console has some code for this?\n[x] replace searched words with highlighted version\n[ ] highlight current matched search item differently than some other\n    - traverse the contents, and change an 'important' to somehting else\n[ ] wrap-around optionally\n[x] going forward 4 times and then going back 4 doesn't work :(\n    maybe related:\n        File \"/usr/lib/python2.7/dist-packages/urwid/widget.py\", line 142, in cached_render validate_size(self, size, canv)\n        File \"/usr/lib/python2.7/dist-packages/urwid/widget.py\", line 112, in validate_size canv.rows(), size))\n        urwid.widget.WidgetError: Widget <Filler box widget <Columns box/flow widget> valign='top'> rendered (193 x 45) canvas when passed size (193, 51\n    [x] (maybe) try cache invalidation?

This option is ignored if any upper\u2010\n       case letters appear in the search pattern; in other words, if  a\n       pattern  contains  uppercase  letters, then that search does not\n       ignore case.\n[ ] -I or --IGNORE-CASE\n       Like -i, but searches ignore case even if the  pattern  contains\n       uppercase letters.\n[ ] add \\c and \\C (insensitive and sensitive, respectively) to the\n   search parsing\n[ ] support set ignorecase? set smartcase?\n[ ] add saveas (to save STDIN input)\n[ ] center single column\n[ ] version string\n    [ ] :version command\n[ ] corner cases when -t and -b \\lim 0\n[ ] for ipython: register .ipynb as a json lexer-able thing\n    pygments.lexers.web.JsonLexer\n[ ] swallow last empty panel in the banner\n[ ] make kanten importable (refactor out the cli aspects to make testing easier)\n[ ] bug - height is exceeded in my piles (off by one?)",
