style: update __init__.py

compat: adapt to the new destspace argument of destmerge The argument is currently ignored in the topic case for simplicity, but we properly accept it and propagate it to the original function to prevent crash and behavior regression in the non-topic case.

stack: prevent crash when topic is rooted on nullid We exclude null from displayed base. This was causing a crash when trying to display its description (we'll still have to handle the empty description case, but it is now less urgent).

test: add topic on the first 2 changesets too This will be used to add a test for topic rooted on nullid. We introduce this in its own changeset to reduce the noise if the actual changeset.

test: remove comment about new head warning The new head warning was buggy. This was fixed in bdc5bb223b50.

stack: also change the indexing of the t# reference Changeset 61f36480740f changed the index displayed (we now index from 1), but forgot to update the logic used to resolve the 't#' name. This changeset fixes it.

stack: change the ascii symbold for base Now that the children line go upward, '_' is no longer clear as is take the lower part of the line. We go for '^' that use the upper part.

stack: reverse the display order Most mercurial command display the most recent changeset first. We put `hg topic --list` inline with this.

topic: extract display from entry computation We are about to reverse the order of the output (most recent first) so it will be useful.

stack: start indexing at 't1' instead of 't0' I think 't0' could have special meaning (eg: before 't1', but still with topic activated) so let's keep room for that. Indexing from 1 is not crazy anyway.

commit: wrap "commitstatus" to take topic into account The "created new head" message was appearing for every single commit made on a topic. It should now properly only appears when a new head is actually created on a topic.

uisetup: add call to 'topicmap.modsetup' this was forgotten in 99c1a26abf3f. Tests did not broke because the wrapping of cg.apply only have performance impact (cache warmup).

uisetup: move all remaining wrapping into uisetup All our wrapping is now properly done at uisetup time. Hooray.

topicmap: move 'cgapply' wrapping into the topicmap module More gathering of related logic.

topicmap: move the 'usetopicmap' context manager into the topicmap module There is no good reason to not have it gathered with the rest.

patch: move setup of import/export logic into a function The function is now called during uisetup.

patch: remove version compatibility check We don't support anything under 3.7.

patch: document the section about import/export

patch: move import/export wrapping close to the function definition This gather similar logic together.

discovery: move all setup into a 'modsetup' function The various wrappings are moved into a function that live in the module and the function is now properly called during 'uisetup'.

revset: add a ui argument to 'modsetup' This is a gratuitous change for consistency with the function that use it.

revset: run 'modsetup' at uisetup time We are slowly moving away from module time wrapping. These thing should be done in the dedicated 'setup' method called by Mercurial.

destination: rename 'setupdest' to 'modsetup' the topic.revset module use 'modsetup' as a name for its setup function. It looks like a good name, lets unify names toward that.

destination: document 'setupdest' Let's make the role of this function clear.

destination: add a ui argument to 'setupdest' This is a gratuitous change for consistency.

destination: make sure 'setupdest' is the latest function in the module Let's introduce some consistency, end of module seems fine.

topicmap: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

stack: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

revset: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

discovery: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

destination: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

init: move to new style import This unify with the new core Mercurial usage and this will make future changes to the imports easier to track.

test: disable the new style rendering for "missing parent" The style kicks in when we display a partial tree. Supporting test running both 3.7 and default with this is painful, we disable the new feature for now.

tests: add pyflakes test

setup: make sure we use the imported module This prevent pyflakes to complains about it (and work around any possible demand import magic. I'm not sure why we do this important dance at all, but I'm leaving it there in doubt.

topicmap: whitespace

topiccache: directly instantiate a topiccache object when reading There is no need to rely on a temporary monkey patching.

readme: fix instruction to enable topic We moved the source code in 85390446f8c1 but we messed up the readme update. We are fixing it here.

stack: whitespace

stack: remove unused import

revset: add missing imports

revset: whitespace

discovery: whitespace

discovery: removed unused oldgetitem

setup: break long line

init: indent correctly

init: whitespace fixups

init: remove unused module

spelling: histedit

spelling: changeset

readme: remove the part about 3.7 and hgext3rd We are using direct path already so we don't need any magic here. The 'hgext3rd.'bit is only required (for 3.7) when the module is installed and we rely on sys.path to find it.

merge with other duplicate head

histedit: restrict default edited set to current topic when possible If we have an active topic, we restrict the edit within that topic.

stack: add a 'stack()' revset We give access to the list of relevant commit with a revset. Benefits over 'topic(.)' are the filtering of obsolete changeset and the reordering (to topological as-in unstability were resolved).

stack: display the base of the stack Displaying the first parent of the stack seems useful. I'm even tempted to call it 't0' and have the topic still active when 'hg up t0' is used to move to the base. As a side effect we gain a way to denote that the stack is not linear. I'm not super convinced that it is the right way to display it, but this is better than no information.

stack: add some default color configuration We can make the output more insightful with some default colors, let's do it.

stack: add basic formatter and label support This still is not great, especially I would like '-T' to be able to control how we display the changeset, but this is useful progress.

stack: show the currently active changeset and unstable ones Still super basic, but give a basic idea of the feature. We use both symbols and explicit text because symbols are cool but text is more explicit

stack: add "t" prefix to index in the output This make the existance and meaning of "t2" reference clearer.

stack: allow to refer to changeset using "t2" form hg up "t0" is seen as "update to the first changeset of my current topic". Eventually we'll drop the "t2" form in favor of the planned generic indexing operator '.{t2}'.
