templater: deprecate --style now that -T exists

templating: make -T much more flexible It can now accept styles and paths and references to settings in [templates].

changeset_templater: remove use_template method

cmdutil: make helper function to process template args

commands: add -T alternative to --template

config: clarify and exemplify the user name in the sample config file

templater: make strings in template expressions be "string-escape"-ed correctly Changeset 64b4f0cd7336 (released with 2.8.1) fixed "recursively evaluate string literals as templates" problem (issue4102) by moving the location of "string-escape"-ing from "tokenizer()" to "compiletemplate()". But some parts in template expressions below are not processed by "compiletemplate()", and it may cause unexpected result. - 'expr' of 'if(expr, then, else)' - 'expr's of 'ifeq(expr, expr, then, else)' - 'sep' of 'join(list, sep)' - 'text' and 'style' of 'rstdoc(text, style)' - 'text' and 'chars' of 'strip(text, chars)' - 'pat' and 'repl' of 'sub(pat, repl, expr)' For example, '\n' of "{join(extras, '\n')}" is not "string-escape"-ed and treated as a literal '\n'. This breaks "Display the contents of the 'extra' field, one per line" example in "hg help templates". Just "string-escape"-ing on each parts above may not work correctly, because inside expression of nested ones already applies "string-escape" on string literals. For example: - "{join(files, '\n')}" doesn't return "string-escape"-ed string, but - "{join(files, if(branch, '\n', '\n'))}" does To fix this problem, this patch does: - introduce "rawstring" token and "runrawstring" method to handle strings not to be "string-escape"-ed correctly, and - make "runstring" method return "string-escape"-ed string, and delay "string-escape"-ing until evaluation This patch invokes "compiletemplate()" with "strtoken=exp[0]" in "gettemplate()", because "exp[1]" is not yet evaluated. This code path is tested via mapping ("expr % '{template}'"). In the other hand, this patch invokes it with "strtoken='rawstring'" in "_evalifliteral()", because "t" is the result of "arg" evaluation and it should be "string-escape"-ed if "arg" is "string" expression. This patch doesn't test "string-escape"-ing on 'expr' of 'if(expr, then, else)', because it doesn't affect the result.

templater: apply "stringify()" on sub expression to get string correctly Templating syntax allows nested expression to be specified as parts below, but they are evaluated as a generator and don't work correctly. - 'sep' of 'join(list, sep)' - 'text' and 'chars' of 'strip(text, chars)' In the former case, 'sep' returns expected string only for the first separation, and empty one for the second or later, because the generator has only one element. In the latter case, templating is aborted by exception, because the generator doesn't have 'strip()' method (as 'text') and can't be passed as the argument to 'str.strip()' (as 'chars'). This patch applies "stringify()" on these sub expression to get string correctly.

templater: avoid recursive evaluation of string literals completely Changeset 3d8bfe2ecf6d (released with 2.8.1) fixed "recursively evaluate string literals as templates" problem (issue4103) by introducing "_evalifliteral()". But some parts in template expressions below are still processed by the combination of "compiletemplate()" and "runtemplate()", and may cause same problem unexpectedly. - 'init' and 'hang' of 'fill(text, width, init, hang)' - 'expr' of 'sub(pat, repl, expr)' - 'label' of 'label(label, expr)' This patch processes them by "_evalifliteral()" instead of the combination of "compiletemplate()" and "runtemplate()" to avoid recursive evaluation of string literals completely.

status: improve explanation of ' ' status a) it shows for states other than 'A' b) it only shows with --copies

revset: changed methods in spanset to return ordered sets Now __sub__ and __and__ can smartly return ordered lazysets.

revset: added sort method to orderedlazyset

revset: added order methods to lazyset classes This will allow revsets to ask for an ordered set when possible to be able to work lazily with it.

setdiscovery: document algorithms used This is taken from: http://programmers.stackexchange.com/questions/208998 And modified slightly.

doc: gendoc.py creates valid output for option descriptions with newlines gendoc.py did not handle the hanging indentation for descriptions. Work around this by joining all in one single line (same as in minirst since previous patch). This problem occurred when translations of option lines were very long. Do not bother the translators with this detail. On a long option description, the translator continued on a new line as usual. gendoc.py created invalid rst syntax like this: -o, --option Description line 1 description line 2 The new output is: -o, --option Description line 1 description line 2 The lines could theoretically become very long, but line breaking is handled when generating the final documentation.

minirst: create valid output when table data contains a newline When table data contained a newline, the result of minirst.maketable did not look nice plus it was not recognised by minirst.format: == === ==== l1 1 one l2 2 2 22 l3 == === ==== This problem occurred when the description of options had a very long translation which was split by newlines. Do not bother a translator with this detail. The multiline translations for option descriptions have been fixed in baf1600adfbe in it.po, de.po and ro.po. I manually did the same as this patch does, I removed the newlines. When a newline was in the description, this created unusable help output: $ hg help somecommand hg somecommand [option]... with somecommand, you can... options: == =================== ======================================================= =================================== --longdesc VALUE xxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -n --norm normal desc --newline VALUE line1 line2 == =================== =============== =========================================================================== now this looks much nicer: ... options: --longdesc VALUE xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -n --norm normal desc --newline VALUE line1 line2

tests: match time by a glob to fix intermittent failures of test-lock-badness.t Sometimes the lock was a bit slower and took 2 seconds. Do not fail the test by this. The glob ? matches from 0 to 9 seconds, which should be enough safety.

merge: adds documentation to the mergestate class Document most the new function involved in the new serialisation process (and a few others).

merge: add blank line between mergestate's method This class is now too big to be a single big block of continuous text.

cmdserver: allow to start server without repository Typical use case is to clone repository through command server. Clone may require user interaction, so command-server protocol is beneficial over raw stdio channels.

cmdserver: prepare test for starting server without repository

histedit: move logic for finding child nodes to new function This function will be used in later patches.

histedit: clean up lock imports We are alread importing the release function from lock, no need to actually import the module too.

localrepo: changed revs to use spanset instead of baseset Performance benchmarking: $ time hg log -qf -l1 ... real 0m1.420s user 0m1.249s sys 0m0.167s $ time ~/local/hg/hg log -qf -l1 ... real 0m0.719s user 0m0.614s sys 0m0.103s

extensions: use normpath to allow trailing '\' on Windows (issue4187) Fixes same issue as 5c794e7331e7 but now works on Windows too. With this patch a trailing backward slash won't prevent the extension from being found on Windows, and we continue to support any combination of forward and back slashes within the path.

tests: fix unused imports from inotify removal caught by pyflakes

revset: added ordered generatorset classes with __contains__ method They stop iterating as soon as they go past the value they are looking for, so, for values not in the generator they return faster.

merge: use the right ancestor when both sides copied the same file The tests shows no real changes because of this ... but there must be some weird corner cases where using the right ancestor for the merge planning is better than using the wrong one.

copies: when both sides made the same copy, report it as a copy Not used yet ... but shows up in debug output.
