Most colorschemes are +written to only support GVim, and don't work at all in terminal Vim. + +This plugin makes GVim-only colorschemes Just Work in terminal Vim, as long +as the terminal supports 88 or 256 colors - and most do these days. This +usually requires no user interaction (but see the help for what to do if +things don't Just Work). After getting this plugin happily installed, any +time you use :colorscheme it will do its magic and make the colorscheme Just +Work. + +Whenever you change colorschemes using the :colorscheme command this script +will be executed. It will take the colors that the scheme specified for use +in the GUI and use an approximation algorithm to try to gracefully degrade +them to the closest color available in your terminal. If you are running in +a GUI or if your terminal doesn't support 88 or 256 colors, no changes are +made. Also, no changes will be made if the colorscheme seems to have been +high color already. + +If for some reason this transparent method isn't suitable to you (for instance +if your environment can't be configured to meet the |csapprox-requirements|, +or you need to work in Vim 6), another option is also available: using the +|:CSApproxSnapshot| command to create a new GUI/88-/256-color terminal +colorscheme. To use this command, a user would generally start GVim, choose a +colorscheme that sets up the desired colors, and then use |:CSApproxSnapshot| +to create a new colorscheme based on those colors that works in high color +terminals. This method is more flexible than the transparent mode and works +in more places, but also requires more user intervention, and makes it harder +to deal with colorschemes being updated and such. + +====== +NOTES +====== + +Ideally, this plugin should require absolutely no configuration, but you may +need some tweaking to make sure vim realizes that your terminal supports more +than 16 colors. Also, konsole and Eterm users will want to make sure that +this plugin realizes that the terminal does not use colors that are exactly +xterm-compatible; they will want to skim through the help articles +|csapprox-palettes| and |csapprox-configuration| for a better end result. + +============== +SCREENSHOTS +============== + +Some quick side-by-side screenshots can be found at +http://www.cs.drexel.edu/~mjw452/CSApprox/ diff --git a/after/plugin/CSApprox.vim b/after/plugin/CSApprox.vim new file mode 100644 index 0000000..4754efa --- /dev/null +++ b/after/plugin/CSApprox.vim @@ -0,0 +1,29 @@ +" Copyright (c) 2012, Matthew J.

Contact Info |csapprox-author| + +The functionality mentioned here is a plugin, see |add-plugin|. +You can avoid loading this plugin by setting the "CSApprox_loaded" global +variable in your |vimrc| file: > + :let g:CSApprox_loaded = 1 + +============================================================================== +1. Introduction *csapprox-intro* + +It's hard to find colorschemes for terminal Vim. Most colorschemes are +written to only support GVim, and don't work at all in terminal Vim. + +This plugin makes GVim-only colorschemes Just Work in terminal Vim, as long +as the terminal supports 88 or 256 colors - and most do these days. This +usually requires no user interaction (but see below for what to do if things +don't Just Work). After getting this plugin happily installed, any time you +use :colorscheme it will do its magic and make the colorscheme Just Work. + +Whenever you change colorschemes using the :colorscheme command this script +will be executed. It will take the colors that the scheme specified for use +in the GUI and use an approximation algorithm to try to gracefully degrade +them to the closest color available in your terminal. If you are running in +a GUI or if your terminal doesn't support 88 or 256 colors, no changes are +made. Also, no changes will be made if the colorscheme seems to have been +high color already. + +If for some reason this transparent method isn't suitable to you (for instance +if your environment can't be configured to meet the |csapprox-requirements|, +or you need to work in Vim 6), another option is also available: using the +|:CSApproxSnapshot| command to create a new GUI/88-/256-color terminal +colorscheme. To use this command, a user would generally start GVim, choose a +colorscheme that sets up the desired colors, and then use |:CSApproxSnapshot| +to create a new colorscheme based on those colors that works in high color +terminals. This method is more flexible than the transparent mode and works +in more places, but also requires more user intervention, and makes it harder +to deal with colorschemes being updated and such. + *:CSApproxSnapshot* +The full syntax for the command is: > + :CSApproxSnapshot[!] /path/to/new/colorscheme +< For example: > + :CSApproxSnapshot ~/.vim/colors/foobar.vim +< +NOTE: The generated colorscheme will only work in 88- and 256-color terminals, + and in GVim. It will not work at all in a terminal with 16 or fewer + colors. There's just no reliable way to approximate down from + 16,777,216 colors to 16 colors, especially without there being any + standard for what those 16 colors look like other than 'orange-ish', + 'red-ish', etc. + +NOTE: Although |:CSApproxSnapshot| can be used in both GVim and terminal Vim, + the resulting colors might be slightly off when run from terminal Vim. + I can find no way around this; Vim internally sets different colors when + running in a terminal than running in the GUI, and there's no way for + terminal Vim to figure out what color would have been used in GVim. + + *:CSApprox* +A command is also provided to run the approximation manually. This might be +useful if some colors were set outside of a colorscheme file, for instance. +By default, it will not change any colors unless no highlight group is set to +a color above 15, which is CSApprox's normal behavior. This probably isn't +useful in most use cases, though. On the other hand, if a ! is provided, +CSApprox will skip that test and update the cterm value for every highlight +group from the corresponding gui color. Syntax: +> + :CSApprox[!] +< + +============================================================================== +2. Requirements *csapprox-requirements* + +For CSApprox to work, there are 2 major requirements that must be met. + +a) GUI support (or vim >= 7.3) *csapprox-gui-support* *csapprox-+gui* + +NOTE This section only applies to vim versions before 7.3.000 - a modern vim +does not need GUI support in order for CSApprox to function. + +If CSApprox is being used to adjust a scheme's colors transparently, then the +terminal "vim" binary that is being run must be built with GUI support (see +|csapprox-limitations| for an explanation). If |:CSApproxSnapshot| is being +used to create a terminal colorscheme for high color terminals, then the +"vim" binary being used to create the scheme must be built with +gui, but the +scheme can be used in terminal "vim" binaries that weren't built with +gui. + +NOTE that creating snapshots with GVim will work better than making them with +Vim, and (obviously) all "gvim" binaries are built with +gui. + +Unfortunately, several Linux distributions only include GUI support in their +"gvim" binary, and not in their "vim" binary. You can check if GUI support is +available with the following command: + :echo has('gui') + +If that prints 0, the first thing to try would be searching for a larger vim +package provided by your distribution, like "vim-enhanced" on RedHat/CentOS +or "vim-gtk" or "vim-gnome" on Debian/Ubuntu. + +If you are unable to obtain a "vim" binary that includes GUI support, but +have a "gvim" binary available, you can probably launch Vim with GUI support +anyway by calling gvim with the |-v| flag in the shell: > + gvim -v + +If the above works, you can remove the need to call "gvim -v" instead of "vim" +all the time by creating a symbolic link from your "gvim" binary to "vim" +somewhere in your $PATH, for example: + sudo ln -s $(which gvim) $(which vim) + +If launching as "gvim -v" doesn"t work, and no package with GUI support is +available, you will need to compile Vim yourself and ensure that GUI support +is included to use CSApprox in its transparent mode, or create a snapshotted +scheme from GVim to use its snapshot mode. If this is inconvenient for you, +make sure that the Vim maintainer for your distribution knows it; they made a +conscious decision to build "vim" without +gui and "gvim" without terminal +support. + +b) Properly configured terminal *csapprox-terminal* + +As said above, many modern terminals support 88 or 256 colors, but most of +these default to setting $TERM to something generic (usually "xterm"). Since +Vim uses the value of the "colors" attribute for the current $TERM in terminfo +to figure out the number of colors used internally as 't_Co', this plugin will +either need for 't_Co' to be set to 88 or 256 in |vimrc|, or for $TERM to be +set to something that implies high color support. Possible choices include +"xterm-256color" for 256 color support and "rxvt-unicode" for 88 color +support. + *csapprox-palettes* +Also, there are at least three different 256-color palettes in use. Nearly +all terminals use an xterm-compatible palette, so most users need not concern +themselves with this, with only two exceptions: Eterm uses a slightly +different palette, and older Konsole (pre KDE 2.2.0) used a third palette. +CSApprox has no reliable way to tell which palette your terminal uses, so it +makes some educated guesses: + + i) If vim thinks that there are 88 colors available, CSApprox will use the + xterm/urxvt-compatible 88 color palette (I don't know of any other + 88 color palette in use anywhere). + + ii) If $TERM starts with "Eterm", CSApprox will approximate based on the + Eterm palette. + + iii) If $TERM starts with "konsole", CSApprox will use the legacy Konsole + palette if either "kde4-config --kde-version" or "kde-config --version" + reports that the KDE version on the system is less than 4.2.0. + Otherwise, it will use the xterm palette. + + iv) If $TERM starts with "xterm" or "screen", then CSApprox looks for the + vim variables "g:CSApprox_eterm" and "g:CSApprox_konsole". + If g:CSApprox_eterm is true, CSApprox uses the Eterm palette. + If g:CSApprox_konsole is true, CSApprox uses the old konsole palette. + Otherwise, CSApprox uses the xterm palette. + + v) For all other $TERM values, CSApprox uses the xterm palette. + + *csapprox-terminal-example* +To turn on high color support despite an incorrect $TERM, you can override +t_Co (the vim name for the terminfo setting defining how many colors are +available) in your .vimrc, and set either CSApprox_konsole or CSApprox_eterm +if appropriate. You could put something like this into your |vimrc|: +> + if (&term == 'xterm' || &term =~? '^screen') && hostname() == 'my-machine' + " On my machine, I use an old Konsole with 256 color support + set t_Co=256 + let g:CSApprox_konsole = 1 + endif + +Gnome Terminal, as of the time that I am writing this, doesn't support having +the terminal emulator set $TERM to something adequately descriptive. In cases +like this, something like the following would be appropriate: +> + if &term =~ '^\(xterm\|screen\)$' && $COLORTERM == 'gnome-terminal' + set t_Co=256 + endif + +============================================================================== +3. Configuration *csapprox-configure* + +There are several global variables that can be set to configure the behavior +of CSApprox. They are listed roughly based on the likelihood that the end +user might want to know about them. + +g:CSApprox_loaded *g:CSApprox_loaded* + If set in your |vimrc|, CSApprox is not loaded. Has no effect on + snapshotted schemes. + +g:CSApprox_verbose_level *g:CSApprox_verbose_level* + When CSApprox is run, the 'verbose' option will be temporarily raised to + the value held in this variable unless it is already greater. The default + value is 1, which allows CSApprox to default to warning whenever something + is wrong, even if it is recoverable, but allows the user to quiet us if he + wants by changing this variable to 0. The most important messages will be + shown at verbosity level 1; some less important ones will be shown at + higher verbosity levels. Has no effect on snapshotted schemes. + +g:CSApprox_fake_reverse *g:CSApprox_fake_reverse* + In gvim, setting a highlight group like "Visual" (the color of your visual + mode selection) to do reverse video results in it reversing the colors of + each character cell under it. Some terminals don't support this and will + instead always use the default background color on the default foreground + color when asked for reverse video. If this variable is set to a non-zero + number, CSApprox will change any request for reverse video to the "Normal" + group's bg color on the "Normal" group's fg color, instead of asking the + terminal to do reverse video. This provides a middle ground for terminals + that don't properly support reverse video - it's worse than having the + terminal properly reverse the colors of each character cell, but it's + better than the broken behavior of some terminal emulators. This was the + default behavior before CSApprox 4.0. + +g:CSApprox_eterm *g:CSApprox_eterm* + If set to a non-zero number, CSApprox will use the Eterm palette when + 'term' is set to "xterm" or begins with "screen". Otherwise, the xterm + palette would be used. This also affects snapshotted schemes. + +g:CSApprox_konsole *g:CSApprox_konsole* + If set to a non-zero number, CSApprox will use the old Konsole palette + when 'term' is set to "xterm" or begins with "screen". Otherwise, the + xterm palette would be used. This also affects snapshotted schemes. + +g:CSApprox_attr_map *g:CSApprox_attr_map* + Since some attributes (like 'guisp') can't be used in a terminal, and + others (like 'italic') are often very ugly in terminals, a generic way to + map between a requested attribute and another attribute is included. This + variable should be set to a Dictionary, where the keys are strings + representing the attributes the author wanted set, and the values are the + strings that the user wants set instead. If a value is '', it means the + attribute should just be ignored. The default is to replace 'italic' with + 'underline', and to use 'fg' instead of 'sp': > + let g:CSApprox_attr_map = { 'italic' : 'underline', 'sp' : 'fg' } +< + Your author prefers disabling bold and italic entirely, so uses this: > + let g:CSApprox_attr_map = { 'bold' : '', 'italic' : '', 'sp' : 'fg' } +< + + Note: This transformation is considered at the time a snapshotted scheme + is created, rather than when it is used. + + Note: You can only map an attribute representing a color to another + attribute representing a color; likewise with boolean attributes. + After all, sp -> bold and italic -> fg would be nonsensical. + + *g:CSApprox_hook_pre* *g:CSApprox_hook_{scheme}_pre* + *g:CSApprox_hook_post* *g:CSApprox_hook_{scheme}_post* +g:CSApprox_hook_pre +g:CSApprox_hook_post +g:CSApprox_hook_{scheme}_pre +g:CSApprox_hook_{scheme}_post *csapprox-hooks* + These variables provide a method for adjusting tweaking the approximation + algorithm, either for all schemes, or on a per scheme basis. For + snapshotted schemes, these will only take effect when the snapshotted + scheme is created, rather than when it is used. Each of these variables + may be set to either a String containing a command to be :execute'd, or a + List of such Strings. The _pre hooks are executed before any + approximations have been done. In order to affect the approximation at + this stage, you would need to change the gui colors for a group; the cterm + colors will then be approximated from those gui colors. Example: +> + let g:CSApprox_hook_pre = 'hi Comment guibg=#ffddff' +< + The advantage to tweaking the colors at this stage is that CSApprox will + handle approximating the given gui colors to the proper cterm colors, + regardless of the number of colors the terminal supports. The + disadvantage is that certain things aren't possible, including clearing + the background or foreground color for a group, selecting a precise cterm + color to be used, and overriding the mappings made by g:CSApprox_attr_map. + Another notable disadvantage is that overriding things at this level will + actually affect the gui colors, in case the :gui is used to start gvim + from the running vim instance. + + To overcome these disadvantages, the _post hooks are provided. These + hooks will be executed only after all approximations have been completed. + At this stage, in order to have changes appear the cterm* colors must be + modified. For example: + *csapprox-transparency* +> + let g:CSApprox_hook_post = ['hi Normal ctermbg=NONE ctermfg=NONE', + \ 'hi NonText ctermbg=NONE ctermfg=NONE' ] +< + Setting g:CSApprox_hook_post as shown above will clear the background of + the Normal and NonText groups, forcing the terminal's default background + color to be used instead, including any pseudotransparency done by that + terminal emulator. As noted, though, the _post functions do not allow + CSApprox to approximate the colors. This may be desired, but if this is + an inconvenience the function named by g:CSApprox_approximator_function + can still be called manually. For example: +> + let g:CSApprox_hook_post = 'exe "hi Comment ctermbg="' + \ . '. g:CSApprox_approximator_function(0xA0,0x50,0x35)' +< + The _{scheme}_ versions are exactly like their counterparts, except that + they will only be executed if the value of g:colors_name matches the + scheme name embedded in the variable name. They will be executed after + the corresponding hook without _{scheme}_, which provides a way to + override a less specific hook with a more specific one. For example, to + clear the Normal and NonText groups, but only for the colorscheme + "desert", one could do the following: +> + let g:CSApprox_hook_desert_post = ['hi Normal ctermbg=NONE ctermfg=NONE', + \ 'hi NonText ctermbg=NONE ctermfg=NONE' ] +< + One final example: If you want CSApprox to be active for nearly all + colorschemes, but want one or two particular schemes to be ignored, you + can take advantage of the CSApprox logic that skips over any color scheme + that is already high color by setting a color to a number above 255. Note + that most colors greater than 15 will work, but some will not - 256 should + always work. For instance, you can prevent CSApprox from modifying the + colors of the zellner colorscheme like this: +> + let g:CSApprox_hook_zellner_pre = 'hi _FakeGroup ctermbg=256' +< + NOTE: Any characters that would stop the string stored in g:colors_name + from being a valid variable name will be removed before the + _{scheme}_ hook is searched. Basically, this means that first all + characters that are neither alphanumeric nor underscore will be + removed, then any leading digits will be removed. So, for a + colorscheme named "123 foo_bar-baz456.vim", the hook searched for + will be, eg, g:CSApprox_hook_foo_barbaz456_post + +g:CSApprox_use_showrgb *g:CSApprox_use_showrgb* + By default, CSApprox will use a built in mapping of color names to values. + This optimization greatly helps speed, but means that colors addressed by + name might not match up perfectly between gvim (which uses the system's + real rgb database) and CSApprox (which uses the builtin database). To + force CSApprox to try the systemwide database first, and only fall back on + the builtin database if it isn't available, set this variable non-zero. + +g:CSApprox_approximator_function *g:CSApprox_approximator_function* + If the default approximation function doesn't work well enough, the user + (or another author wishing to extend this plugin) can write another + approximation function. This function should take three numbers, + representing r, g, and b in decimal, and return the index on the color + cube that best matches those colors. Assigning a |Funcref| to this + variable will override the default approximator with the one the Funcref + references. This option will take effect at the time a snapshotted scheme + is created, rather than when it's used. + +g:CSApprox_redirfallback *g:CSApprox_redirfallback* + Until Vim 7.2.052, there was a bug in the Vim function synIDattr() that + made it impossible to determine syntax information about the |guisp| + attribute. CSApprox includes a workaround for this problem, as well as a + test that ought to disable this workaround if synIDattr() works properly. + If this test should happen to give improper results somehow, the user can + force the behavior with this variable. When set to 1, the workaround will + always be used, and when set to 0, synIDattr() is blindly used. Needless + to say, if this automatic detection should ever fail, the author would + like to be notified! This option will take effect at the time a + snapshotted scheme is created, rather than when it's used. + +============================================================================== +4. Rationale/Design *csapprox-design* + +There is a wealth of colorschemes available for Vim. Unfortunately, since +traditional terminal emulators have only supported 2, 8 or 16 colors, +colorscheme authors have tended to avoid writing colorschemes for terminal +Vim, sticking instead to GVim. Even now that nearly every popular terminal +supports either 88 or 256 colors, few colorschemes are written to support +them. This may be because the terminal color codes are just numbers from 0 to +87 or 255 with no semantic meaning, or because the same number doesn't yield +the same color in all terminals, or simply because the colorscheme author +doesn't use the terminal and doesn't want to take the time to support +terminals. + +Whatever the reason, this leaves users of many modern terminal emulators in +the awkward position of having a terminal emulator that supports many colors, +but having very few colorschemes that were written to utilize those colors. + +This is where CSApprox comes in. It attempts to fill this void allowing GVim +colorschemes to be used in terminal Vim. CSApprox has two distinct modes of +operation. In the first mode, it attempts to make GVim colorschemes +transparently backwards compatible with terminal Vim in a high color terminal. +Basically, whenever a colorscheme is run it should set some colors for the +GUI, and this script will then run and attempt to figure out the closest color +available in the terminal's color palette to the color the scheme author asked +for. Unfortunately, this does not work well all the time, and it has some +limitations (see |csapprox-limitations|). Most of the time, however, this +gives a very close approximation to the GVim colors without requiring any +changes to the colorscheme, or any user interaction. It only requires that +the plugin be installed on the machine where Vim is being run, and that the +user's environment meets the needs specified at |csapprox-requirements|. In +the event that this doesn't work, a second option - using |:CSApproxSnapshot| +to create a new, 88-/256-color capable colorscheme - is available. + +Ideally, the aim is for CSApprox to be completely transparent to the user. +This is why the approach I take is entirely different from the GuiColorScheme +script, which will break on any but the simplest colorschemes. Unfortunately, +given the difficulty of determining exactly which terminal emulator the user +is running, and what features it supports, and which color palette it's using, +perfect transparency is difficult. So, to this end, I've attempted to default +to settings that make it unlikely that this script ever makes things worse +(this is why I chose not to override t_Co to 256 myself), and I've attempted +to make it easy to override my choice of defaults when necessary (through +g:CSApprox_approximator_function, g:CSApprox_konsole, g:CSApprox_eterm, +g:CSApprox_attr_map, etc). + +In the event that the transparent solution is undesirable, or that the user's +environment can't be configured to allow it (no GVim and no Vim with +gui, for +instance), |:CSApproxSnapshot| should provide a workable alternative - less +cool, and less flexible, but it will work in more environments, and the +snapshotted colorscheme will even work in Vim 6. + +If any of my design choices seem to be causing extra work with no real +advantages, though, I'd like to hear about it. Feel free to email me with any +improvements or complaints. + +============================================================================== +5. Known Bugs and Limitations *csapprox-limitations* + +GUI support or vim >= 7.3 is required for transparently adapting schemes. + + There is nothing I can do about this given my chosen design. CSApprox works + by being notified every time a colorscheme sets some GUI colors, then + approximating those colors to similar terminal colors. Unfortunately, when + Vim < 7.3 is not built with GUI support, it doesn't bother to store the GUI + colors, so querying for them fails. This leaves me completely unable to + tell what the colorscheme was trying to do. See |csapprox-+gui| for some + potential workarounds if your distribution doesn't provide a Vim with +gui + and you can't upgrade to a modern vim. + +User intervention is sometimes required for information about the terminal. + + This is really an insurmountable problem. Unfortunately, most terminal + emulators default to setting $TERM to 'xterm', even when they're not really + compatible with an xterm. $TERM is really the only reliable way to + find anything at all out about the terminal you're running in, so there's no + way to know if the terminal supports 88 or 256 colors without either the + terminal telling me (using $TERM) or the user telling me (using 't_Co'). + Similarly, unless $TERM is set to something that implies a certain color + palette ought to be used, there's no way for me to know, so I'm forced to + default to the most common, xterm's palette, and allow the user to override + my choice with |g:CSApprox_konsole| or |g:CSApprox_eterm|. An example of + configuring Vim to work around a terminal where $TERM is set to something + generic without configuring the terminal properly is shown at + |csapprox-terminal-example|. + +Some colorschemes could fail to be converted if they try to be too smart. + + A colorscheme could decide to only set colors for the mode Vim is running + in. If a scheme only sets GUI colors when the GUI is running, instead of + using the usual approach of setting all colors and letting Vim choose which + to use, my approach falls apart. My method for figuring out what the scheme + author wants the scheme to look like absolutely depends upon him setting the + GUI colors in all modes. Fortunately, the few colorschemes that do this + seem to be, by and large, intended for 256 color terminals already, meaning + that skipping them is the proper behavior. Note that this will only affect + transparently adapted schemes and snapshots made from terminal Vim; + snapshots made from GVim are immune to this problem. + +Transparently adapting schemes is slow. + + For me, it takes Vim's startup time from 0.15 seconds to 0.35 seconds. This + is probably still acceptable, but it is definitely worth trying to cut down + on this time in future versions. Snapshotted schemes are faster to use, + since all of the hard evaluations are made when they're made instead of when + they're used. + + NOTE: As of CSApprox 3.50, the overhead is down to about 0.10 seconds on my + test machine. + +It isn't possible to approximate only a particular set of groups. + + Unfortunately, the :CSApprox command will always update all groups, even if + only a small set of groups has changed. A future improvement would be to + provide a function called, say, CSApprox(), that takes an optional list of + highlight groups (default: all) and only does approximation for those + groups. + +============================================================================== +6.
