# Change User Description Committed
#2 4332 Chris Comparini Re-branched, this time getting everyone's versions of jam.
#1 4329 Chris Comparini Initial setup as per public depot instructions.
//guest/perforce_software/jam/src/jamgram.yy
#13 3065 Perforce staff Support for 'actions ...
maxline value', to set a command
specific maxline (rather than the OS-specific maximum).

Undocumented.
#12 2559 rmg Fix 'var on target ?= value' so that var is only set if it
did not have a target-specific value.  Previously, it would
just overwrite the var's value.

Bug fix documented in RELNOTES.

#11 2493 rmg Rewrite the past: update all jam's source with comments to
reflect changes since about 2.3, very early 2001.

Whitespace only change.

Note: I regenerated jamgram.c on my linux 7.3 system prior to
the submit, since patch was so unhappy trying to lay down the
changes from Christopher's change. Presumably this is just due to
different yacc/bison/whatever particulars on the system where
Christopher made the changes originally. - rmg
#10 2490 rmg Jam langauge work: make 'return' actually return from the rule,
rather than just setting the return value.  Introduce new
break/continue statements for managing loops.

User visible change to be documented in Jam.html.

=== computer:1666: Change 37200 by seiwald@play-seiwald on 2002/10/22 15:41:28

Gross rework of Jam.html documentation, including:

- the description of parameters for rules
- description of -g flag
- a new description of targets
- more about rules and their return values
- better separation of rules and updating actions
- putting borders around the tables

(Undocumented) change to documentation.

=== computer:1666: Change 37551 by seiwald@waffle-cyg-seiwald on 2002/11/03 23:17:12

Document jam's new and working break/continue/return statements.

#9 2482 rmg Jam.html partial rewrite and the support for named
parameters to rules.

=== computer:1666: Change 34516 by seiwald@play-seiwald on 2002/06/21 23:59:12
#8 1535 Perforce staff Define YYMAXDEPTH to 10000 to handle right-recursive rules.
#7 1497 Perforce staff Support for invoking rules via variable expansion, i.e.
"$(rule) targets : sources ;".

Not yet documented.

Documented in Jam.html (rmg change 1536)
#6 1492 Perforce staff Replace action modifiers EXEC_* from compile.h with RULE_* flags
from rules.h.  They've always been the same quantity defined in
two places.  Note that RULE_NEWSRCS is now RULE_UPDATED, to be
consistent with 'actions updated'.

No functional change.
#5 1489 Perforce staff Revert syntax of "expr : expr `in` expr" to jam 2.3's
"expr : arg `in` list", because:

a) It broke the precedence of `in` so that it was looser than
!, parsing "! xxxx in yyy" as '( ! xxx ) in yyy".

b) It didn't allow providing an in line list as "$(f) in a b c".

Change to unreleased behavior.
#4 1319 rmg Jam 2.3 + Perforce's internal changes.

This change is a drop of the Perforce internal Jam changes
since the 2.3 public release. The individual changes
represented herein are preserved in the
//guest/richard_geiger/intjam/ branch.

The intent of this drop is to provide a base, from which other
contributors' Jam branches may be integrated into. It is not
intended to become a packaged release in this state. We will
be integrating changes from other users prior to creating the
next packaged release.

Please refer to the src/RELNOTES file for an overview of the
changes present in this integration.
