formatter: convert status command

ui: add formatter method

formatter: add basic formatters

encoding: introduce utf8-b helpers

graphmod: add config cache Before, we'd lookup the branch for every edge segment in the entire graph: extremely expensive. This happened even when no per-branch settings existed. Now we define a revision -> config cache function that's LRU-cached and is a no-op when no configuration exists. Still not terribly fast, but hopefully only one real branch lookup per revision. This might degenerate for wide graphs as the LRU is hard-coded to 20 elements.

graphmod: rewrite graph config validation Our goal is not to strictly disallow _invalid_ input, simply disallow _hostile_ input. Avoid using re Avoid creating empty dicts when no branch parameters are recognized

graph: in hgrc specify line color for main branch You can specify color to visually distinguish main branch (trunk) on hgweb's graph page. If color specified, all branch heads will share same color. Settings format is branch_name.color = value, where color is six hexadecimal digits e.g.: [graph] default.color = FF0000

graph: in hgrc specify line width for main branch You can specify width to visually distinguish main branch (trunk) on hgweb's graph page. Settings format is branch_name.width = value, where width in px e.g.: [graph] default.width = 3

filemerge: remove some redundancy in decorators/docstrings

filemerge: create detail of internal merge tools from documentation string this patch introduces 'internaltoolsmarker' which creates detail of each internal merge tools from documentation string for 'hg help merge-tools'.

filemerge: refactoring of 'filemerge()' current 'filemerge.filemerge()' implementation is verfy complicated. - it is not easy to add new internal merge tools (only by patching on 'filemerge()', or replacing it completely) - cleanup of temporary files is unsatisfactory ('internal:dump' does not, in fact) this is patch for refactoring of 'filemerge()' to isolate each internal merge tool implementations from 'filemerge()', and clean up common part in it.

patch: fuzz more aggressively to match patch(1) behaviour The previous code was assuming a default context of 3 lines. When fuzzing, it would take this value in account to reduce the amount of removed line from hunks top or bottom. For instance, if a hunk has only 2 lines of bottom context, fuzzing with fuzz=1 would do nothing and with fuzz=2 it would remove one of those lines. A hunk with one line of bottom context could not be fuzzed at all. patch(1) has apparently no such restrictions and takes the fuzz level at face value. - test-import.t: fuzz/offset changes at the beginning of file are explained by the new fuzzing behaviour and match patch(1) ones. Patching locations are different but those of my patch(1) do not make a lot of sense right now (patched output are the same) - test-import-bypass.t: more agressive fuzzing makes a patching supposed to fail because of context, succeed. Change the diff to avoid this. - test-mq-merge.t: more agressive fuzzing would allow the merged patch to apply with fuzz, but fortunately we disallow this behaviour. The new output is kept. I have not enough experience with patch(1) fuzzing to know whether aligning our implementation on it is a good or bad idea. Until now, it has been the implementation reference. For instance, "qpush" tolerates fuzz (test-mq-merge.t runs the special case of pushing merge revisions where fuzzing is forbidden).

patch: fix fuzzing of hunks without previous lines (issue3264) When applying hunks such as: @@ -2,1 +2,2 @@ context +change fuzzing would empty the "old" block and make patchfile.apply() traceback. Instead, we apply the new block at specified location without testing. The "bottom hunk" test was removed as patch(1) has no problem applying hunk with no context in the middle of a file.

patch: make hunk.fuzzit() compute the fuzzed start locations - It moves hunks processing weirdness where it belongs - It helps reusing said weirdness whenever fuzzit() is called, like during the actual hunk fuzzing.

patch: fuzz old and new lines at the same time In theory, the fuzzed offsets for old and new lines should be exactly the same as they are based on hunk parsing. Make it true in practice.
