ui: remove superfluous indent in _write()

smartset: reorder initialization of baseset in more intuitive way What we want to do is to assign either _set or _list per the given data type.

config: update the Windows example config file We move from the color extensions to the 'ui.color' config.

help: use 'churn' instead of 'color' as an example extension The 'color' extensions is now deprecated.

config: suggest the 'ui.color' instead of the 'color' extension The extensions is deprecated now so we should offer the core way to handle color instead.

color: update main documentation Now that the feature no longer lives in the extension, we document it in the help of the core config. This include the new 'ui.color' option introduced in the previous changesets. As a result the color extensions can now be deprecated. This is a documentation patch only; color is still disabled by default.

pager: drop the 'color' dependant code The 'color' implementation is in core and no longer wrap '_runcommand'. We drop the extra complexity.

color: cleanup 'debugcolor' logic Now that style are carried by the 'ui' object, we no longer need complicated logic to restore the original style. We just need to copy the 'ui' and work on the copied version.

color: move 'debugcolor' into the 'debugcommands' modules This is the last bits we needed to move out of the extensions. 'hgext/color.py' now only contains logic to changes the default color behavior to 'auto'. However, more cleanups are on the way and we need to document the new config directly in core.

color: rename '_styles' to '_defaultstyles' for clarity This should make it clear the dict is only used for new config. Extensions should not modify it directly anyway since we have 'extraloader' logic for loading '_styles' too.

color: move 'styles' definition on the 'ui' object Same logic as for '_terminfoparams'. The content depends on the config so it should be specific to each 'ui instance.

color: pass 'ui' to 'win32print' Same logic as before,'win32print' relies on some data we will move on the 'ui' object soon, we update the API beforehand for clarity.

color: move the dict with terminfo parameters on the ui object This dictionnary is affected by the content of the config, so we should have one for each ui config. We rename the global dict to '_baseterminfoparams' to make the situation clearer.

color: add ui to effect rendering We'll carry more and more color specific data on the ui object. This will help isolating different color configuration from each other. For example repository config might configure special style that should not affect other ui object. The first step is to make sure the ui object is available were we will needs it.

color: initialize color for the localrepo ui The 'ui' object dedicated to a 'localrepo' is independent from the one available in dispatch (and 'uisetup'). In addition, it is created from the 'baseui' (apparently for good reason). As a result, we need to run the color setup on it after the local repository config is read. This was overlooked when the rest of the initialization changed but did not had impact yet because all setup is still global. We fix it before it is too late.

color: add a 'ui.color' option to control color behavior This new option control whether or not color will be used. It mirror the behavior of '--color'. I usually avoid adding new option to '[ui]' as the section is already filled with many option. However, I feel like 'color' is central enough to deserves a spot in this '[ui]' section. For now the option is not documented so it is still marked as experimental. Once it get documented and official, we should be able to deprecate the color extensions. There is more cleanup to do before that documentation is written, but we need this option early to made them. Having that option will allow for more cleanup of the initialisation process and proper separation between color configuration.

color: reinvent dictionary move the module lever dictionary declaration to a more standard (and practical indentation)

chg: deduplicate error handling of ui.system() This moves 'onerr' handling from low-level util.system() to higher level, which seems better API separation.

chg: refactor ui.system() to be partly overridden Since fd598149112b changed the signature of ui.system(), chgui.system() should have been updated. This patch factors out the util.system() call so that chg can override how a shell command is executed.

color: have the 'ui' object carry the '_colormode' directly Before this changeset, the value was carried by the class to work around limitation of the extensions initialisation. Now that the initialisation is cleanly handled in 'dispatch', we can drop this work around.

color: move triggering of the initialisation logic in core We now run the color initialisation as part of the standard dispatch. This is opening the way for multiple cleanups since we now have access to the multiple 'ui' object and we'll be able to see difference between global and local config. This cleanup will arrive in later changesets. As a side effect, the '--color' flag is now working without the extension. Since we now properly initialize color for each ui idependently, we get a warning message twice.

color: add the definition of '--color' in core If we want to be able to move the initialisation in core, we need core to be aware of that '--color' flag at all time. So we now have the definition in core. That flag is currently unprocessed without the extensions (will be fixed soon). In addition the default value for this flag in core is 'never'. Enabling the extensions change that default value to 'auto'.

color: handle 'ui.plain()' directly in mode setup If 'ui.plain()' is set we should not colorize. We move that logic into the function that determine and setup the color mode. As all other code respect the resulting mode this will be equivalent.

color: move git-subrepo support into the subrepo module Now that all ui instance carry a '_colormode' attribute, we can access and comply to it directly in the subrepo code. The actual implementation could probably be a bit smarter, but we stick close to the current one for the sake of simplicity.

color: move 'modesetup' into the core module Yet another piece of code moving from the extensions to the module in core!

color: move 'terminfosetup' into the core module Another step closer to have all the logic living in core

subrepo: run the repo decoders when archiving The decoders were already run by default for the main repo, so this seemed like an oversight. The extdiff extension has been using 'archive' since 68822b7cdd01 to support -S, and a colleague noticed that after diffing, making changes, and closing it, the line endings were wrong for the diff-tool modified files in the subrepository. (Files in the parent repo were correct, with the same .hgeol settings.) The editor (Visual Studio in this case) reloads the file, but doesn't notice the EOL change. It still adds new lines with the original EOL setting, and the file ends up inconsistent. Without this change, the first file `cat`d in the test prints '\r (esc)' EOL, but the second doesn't on Windows or Linux.

wix: include the help for pager Similar (I assume) to 65d2538ac993.

manifest: check 'if x is None' instead of 'if not x' The old code here would end up executing __len__ on a tree manifest to determine if 'not _data' was true or not. This was very expensive on large repos. Since this function just cares about memoization, we can just check 'if _data is None' instead and save a bunch of time.
