Adds a template function that executes a revset and returns the list of
revisions as the result. It has the signature 'revset(query [, args...])'. The
args are optional and are applied to the query string using the standard
python string.format(args) pattern. This allows things like:
'{revset("parents({0})", rev)}' to produce the parents of each individual
commit in the log output. If no args are specified, the revset result is
cached for the duration of the templater; so it's better to not use args if
performance is a concern.
By itself, revset() can be used to print commit parents, print the common
ancestor of a commit with the main branch, etc.
It can be used with the ifcontains() function to do things like
'{ifcontains(rev, revset('.'), label(...), ...)}' to color the working copy
parent, to color certain branches, to color draft commits, etc.
Adds a template function with the signature 'ifcontains(item, set, then[,
else])'. It can be used to do things like '{ifcontains('.hgignore',
file_mods, label(...), ...)}' to color commits that edit the .hgignore file.
A future patch will add the revset() function which will combine with
ifcontains to allow us to color commits if they are in the revset.
Pure mercurial (i.e. without c extensions) does not support partialmatch() on
the revlog index, so we must fall back to use revlog._partialmatch() to handle
that case for us. The tests caught this.
We don't use revlog._partialmatch() for the normal case because it performs a
very expensive index iteration when the string being tested fails to find a
unique result via index.partialmatch(). It does this in order to filter
out hidden revs in hopes of the string being unique amongst non-hidden revs.
For the shortest(node) case, we'd prefer performance over worrying about
hidden revs.
Adds a pad template function with the following signature:
pad(text, width, fillchar=' ', right=False)
This uses the standard python ljust and rjust functions to produce a string
that is at least a certain width. This is useful for aligning variable length
strings in log output (like user names or shortest(node) output).
Adds a '{shortest(node)}' template function that results in the shortest hex node
that uniquely identifies the changeset at that time. The minimum length can be
specified as an optional second argument and defaults to 4.
This is useful for producing prettier log output, like so:
@ durham shortestnode
| 77cf template: add pad function for padding output
|
o durham
| b183 template: add shortestnode keyword
|
o pierre-yves @
| 6545 backout: add a message after backout that need manual commit
|
| o durham manifestcache
|/ 93f0 manifest cache
|
| o durham catperf
| | c765 cat: increase perf when catting single files
| |
| o durham
|/ 9c53 changectx: increase perf of walk function
|
Running `hg log --style compact` (or any other style) raised a traceback when
no template directory was there. Now there is a message:
Abort: style 'compact' not found
(available styles: no templates found, try `hg debuginstall` for more info)
There is no test because this would require to rename the template directory.
But this would influence other tests running in parallel. And when the test
would be aborted the wrong named directory would remain, especially a problem
when running with -l.
Before the templater got extended for nested expressions, it made
sense to decode string escapes across the whole string. Now we do it
on a piece by piece basis.
This allows using a template keyword on calls to the sub function and brings
the function inline with most other semantics of the other template functions.
During merge of branches, it is useful to compare merge results against
the two parents. This change adds this support to hgweb. To specify
which parent to compare to, use rev/12300:12345 where 12300 is a
parent changeset number. Two links are added to changeset web page so
that one can choose which parent to compare to.
If a template iterator is implemented with generator, the iterator is exhau=
sted
after we use it. This leads to undesired behavior in template. This chang=
e
converts a generator-based iterator to list-based iterator when template en=
gine
first detects a generator-based iterator. All future usages of iterator wi=
ll
use list instead.
These leaks may occur in environments that don't employ a reference
counting GC, i.e. PyPy.
This implies:
- changing opener(...).read() calls to opener.read(...)
- changing opener(...).write() calls to opener.write(...)
- changing open(...).read(...) to util.readfile(...)
- changing open(...).write(...) to util.writefile(...)
Before this, to display file copies in templates, you had to write something
like {file_copies%filecopy}. For some reason, the {file_copy} subtemplate was
used by default but not defined by default in changeset_templater, while styles
were already using it. Here we define {file_copy} in changeset_templater, and
change the templater to handle formatting strings like {file_copies%filecopy}
with already expanded keys (in this case {file_copies}), for backward
compatibility.
Currently hgweb is not streaming its output -- it accumulates the
entire response before sending it. This patch restores streaming
behaviour. To avoid having to synchronously write many tiny fragments,
this patch also adds buffering to the template generator. Local
testing of a fetch of a 100,000 line file with wget produces a slight
slowdown overall (up from 6.5 seconds to 7.2 seconds), but instead of
waiting 6 seconds for headers to arrive, output begins immediately.
- make renamelink take a context
- pass current node to shortlog page rather than tip
- pass user/desc/date/rename to filediff
- improve template error reporting for foo%bar
- use non-grouping operator to avoid some extra processing
- avoid copying and updating defaults
- unnest main template body
- avoid returning extra empty string if format
to use, "hg log --style=changelog". makes different output with no
flags, -q, -v, --debug.
templater module has new template filters for this.
email - committer email address
fill68 - refill text to 68 colums
fill76 - refill text to 76 colums
tabindent - prefix every not empty line with tab
shortdate - iso 8631 date, no time zone
stringify - turn template iterator into string
change name of key in map file from changelog to changeset.
rename command map files to start with map-cmdline.
rename ui.logmap to ui.style in hgrc.
now --style=foo does this:
tries to open foo as file.
tries as map-cmdline.foo in template path.
tries as foo in template path.
rename --map-file to --style.
no more -t alias for --template.
update docs.
rename template entry in map files to changelog.
if --verbose, use changelog_verbose if there, else changelog.
get string code to parse escapes. uses eval now, should parse strings
itself soon.
let caller check if fragment is defined using "in".
make templatepath take optional file name.
