1 [+] PWD/Pwd built-in added; usage:
3 [+] SORT/Sort built-in added; usage:
4 sorted = [ SORT $(list) ] ;
5 [+] COMMAND/Command built-in added; usage:
6 res = [ COMMAND shellcmd-list [[ : options ]] ];
8 exit-status, exit-code:
9 return exit code as last list element
11 don't return command output
13 don't trim command output;
14 default: trim left and right
16 don't left-trim command output
18 don't right-trim command output
19 status-first, code-first:
22 parse output as list (break on whitespaces -- <= ' ')
24 don't break on spaces (' ') when 'parse-output' activated
26 don't break on tabs ('\t') when 'parse-output' activated
27 no-nl-break, no-lf-break:
28 don't break on LF ('\n') when 'parse-output' activated

31 [+] COMMAND/Command built-in synthax changed; new synthax:
32 res = [ COMMAND shellcmd-list [[ : options ]] ];
33 new options (added to common description)
34 [+] COMMAND/Command built-in now can parse command output
37 # VAR = [ RemoveOpt options-to-remove : options-list ] ;
38 # remove options from list
39 [+] rule RemoveOptWild
40 # VAR = [ RemoveOpt regexp-options-to-remove : options-list ] ;
41 # remove options from list with egrep-like regexps
44 # set compile flags for profile; works only for gcc/g++
46 # none, default: don't change
47 # empty: remove optimisation flags
48 # speed: optimise for speed and pIII
49 # size: optimise for size
50 # debug: don't optimize, add debug info
52 [+] rule ObjectNoAliasing
53 # ObjectNoAliasing filelist ;
54 # turn off aliasing optimization for specified files
55 # works only for gcc/g++
57 [*] MainC++ wasn't working properly
58 [*] XXXC++ variables changed to XXXC++ZZZ (MainC++ --> C++Main)
59 [+] LOCATE_BIN and ALL_LOCATE_BIN variables added (for Main and MainC++ targets)
60 so now one can do something like this:
61 ALL_LOCATE_TARGET = $(TOP)/build/obj ;
62 ALL_LOCATE_BIN = $(TOP)/build ;
63 and have a nice bunch of *.o files in build/obj and binary in build/
64 [+] new rule: lib-config
65 call $(1) --cflags and $(1) --libs (many libs provides such configurators)
66 add necessary flags to compiler and linker vars
67 return "tan" (non-empty string) if library is present
68 if $(2) != "" -- don't add flags, just check
69 [+] PATH_SEPARATOR variable added
70 [*] build process changed (.o and .a moved to subdir)
71 [+] allow []...] and [^]...] in globs (so ranges can include ']')
72 [+] :Q now quotes all special shell chars, not only '\'
73 [*] some regexprs was broken by tab expansion; fixed
74 [*] OPTIMC++ renamed to C++OPTIM
76 [+] LOCATE_LIB, LOCATE_LIBSO and ALL_LOCATE_LIB[SO] variables added (for Library and SharedLibrary targets)
77 so now one can do something like this:
78 ALL_LOCATE_TARGET = $(TOP)/build/obj ;
79 ALL_LOCATE_LIB = $(TOP)/build/liba ;
80 ALL_LOCATE_LIBSO = $(TOP)/build/libso ;
81 ALL_LOCATE_BIN = $(TOP)/build ;
82 and have a nice bunch of files in various dirs.
84 [*] JAMCMDARGS now set before parsing Jamfiles (and what sense was to set it after? %-)
85 [+] JAM_TARGETS variable added; scripts are free to modify it, so we can easy define targets from whithin
87 [+] SubIncludeOnce varname : TOP ... ;
88 will do SubInclude iff 'varname' is not set (and will set 'varname')
89 so one can include all necessary libraries in all necessary projects
91 [+] partial Objective C support:
92 ObjC-Main, std. set of OBJC* vars
93 OBJC_GNUSTEP_BASE_LIB = gnustep-base ;
94 OBJC_GNUSTEP_GUI_LIB = gnustep-gui ;
95 rules: ObjCUseGNUstepBase, ObjCUseGNUstepGui, ObjCUseGNUstep
97 [+] 'lib-config-ex' rule:
98 lib-config-ex "command" : "var-name-to-modify"
99 "var-name-to-modify" can be omited;
100 rule returs value of command
103 Echo-n: same as Echo, but does not writes '\n'
104 O-Flush: flush standard output (for Echo-n)
105 [+] added rules: LinkFlagsOn, C++LinkFlagsOn, ObjCLinkFlagsOn
106 same as Object*Flags, but for linker flags
107 we need this due to 'gristing' in multidir builds
109 [+] new variable: JAM_FORCE_GCC_OPTIONS
110 set it to override GCC detection
112 [+] rule set-profile:
113 selects 'debug', 'standard', 'speed' or 'size' profile according to vars:
116 OPT_SPEED = 1 : speed
119 [+] rule set-default-subdir-locates (sets my defaults for ALL_LOCATE_XXX: _build/, etc)
121 [+] alias for set-default-subdir-locates: set-default-target-locations ;
125 [+] jam now correctly creates dirs for files like 'dir/source'
126 [+] alias for set-default-subdir-locates: set-default-locations ;
128 [+] added acions for WINDOZE=1 (my own way to cross-build windoze soft with wine and mingw)
130 WINE -- wine command; default is "wine"
131 MGPATH -- path to mingw bin dir; default is "c:\mingw\bin\" (note the last '\')
132 MGCC -- mingw gcc compiler name; default is "mingw32-gcc.exe";
133 MG -- mingw g++ compiler name; default is "mingw32-g++.exe -static-libgcc"
134 vars for 'windoze-fix' rule (this rule should be invoked in Jamrules; it is harmless to
135 invoke it for any build scheme):
136 WINDOZE_THREADS -- if not empty, add "-mthreads"
137 WINSUBSYS -- either 'console' or 'windows'; default is 'console'
138 WINLIBS -- list of windoze libraries to add; default is '-lkernel32'
140 [!] WARNING! COMPATIBILITY BREAKING CHANGE!
141 [*] old SubInclude rule renamed to SubIncludeMany
142 [*] new SubInclude rule works as SubIncludeOnce (autogenerates guard var)
144 [+] new built-in: [ ExprI1 num0 op num1 ]
145 integer math; understands 5 standard ops ('%' as C '%')
146 [ ExprI1 40 + 2 ] ==> "42"
147 it also understands "<", "<=", ">", ">=", "=" and "!="
148 [+] [ ExprI1 "#" string ] -- return string length
149 [+] new built-in: [ Split str : delims ]
150 split `str` using `delims`
151 [ Split "a,b,c;d" : ",;" ] ==> a b c d
152 if `delims` is not specified, split string to chars
154 [+] lexer now needs less spaces (and sometimes more quoting)
155 [+] added header caching (when using set-default-locations rule)
157 [+] new build-in: [ NormPath pathstr ]
158 it will add 'pwd' if path is not absolute and will try to resolve some '.' and '..'
159 (only leading '..' though).
160 it can be used in SubDir replacement to automate dir building
162 [+] added 'rule name expansion':
163 rule print-foo { Echo "foo" ; }
167 [+] added default 'help' and 'push' targets
168 redefine actions AShowHelp and AGitPush in Jamrules to use the correspoinding target
170 [+] added help-profile target
172 [+] new variables: CFLAGS.all, OPTIM.all, LINKFLAGS.all, LINKLIBS.all
173 profile now sets *.all flags
175 [+] K8JAM-PROGRESS-TIME-DELTA variable (float, seconds between progress/time indicator)
177 [+] regexp engine now undestands some character classes (like :space:) and non-greedy ops
179 [+] call 'check-setup-windoze' rule to enable WINDOZE=1 builds
180 [+] setup-windoze rule will setup windoze build regardless of WINDOZE=1
181 [+] call use-mingw32 rule to use i686-pc-mingw32 crosscompiler instead of wine
182 [+] call windoze-fix after setting WINDOZE_THREADS, WINLIBS and WINSUBSYS
184 [+] sys-has-command cmd -- perform `which`, return "tan" or ""
186 [+] new built-in: ListLength
188 [+] `PreUserObject` rule
189 this rule will be called before `Object` rule decides how to build something;
190 the calling convention is the same as for `UserObject`, but `PreUserObject`
191 should return non-empty string if it wants to bypass default generator rules.
193 [+] documentation: built-in DependsList
195 returns a list of child dependencies for a given target
197 [+] new built-ins: HaveRule, HaveActions
198 HaveRule rulename [rulename...] [ : glob/regexp case-insensitive ignore-case ]
199 HaveActions rulename [rulename...] [ : glob/regexp case-insensitive ignore-case ]
200 returns non-empty string if all specified rules or actions are defined
201 note that we can have rule without actions and actions without rule
202 specify `glob` option to treat names as shell-like globs
203 specify `regexp` option to treat names as regexps
204 specify `case-insensitive` option to ignore case
206 [+] new built-in: ForceFile
207 reverts NoFile effect
209 [+] added flags to Glob and Match: now we can use globs and regexps, and do
210 that ignoring the case.
212 [+] new rule: FileExists fname [fname...] ;
213 returns non-empty string if all files exists; understand pathes.
228 [+] set-default-locations now recognizes DEBUG and respects BUILD_DIR
230 [+] new variables: CC.standard and C++.standard; defaults to gnu99 and gnu++98 if set-profile called
232 [+] new rule: DetectLibrary libnames [: includes [: pathes]]
233 default path list is $(DETECT_LIBRARY_PATH)
234 it will check $(p)/lib for library and $(p)/include for header
235 returns prefix or empty list
237 LIBJIMTCL_PFX = [ DetectLibrary libjim.a : jim.h : /opt/jim /opt/jim-tcl ] ;
238 if $(LIBJIMTCL_PFX) {
239 LINKFLAGS.all += -L$(LIBJIMTCL_PFX)/lib ;
240 LINKLIBS.all += -ljim ;
241 HDRS += $(LIBJIMTCL_PFX)/include ;
242 DEFINES += USE_JIM_TCL ;
245 [+] you can set K8JAM-JOBS variable to force number of jobs
247 [+] use DBG=1 to suppress NDEBUG define for non-debug profiles
249 [+] easy independent targets in *Main:
250 specify independent target name as 3rd arg to *Main:
251 Main alsatest : alsatest.c : alsatest ; # or Main alsatest : alsatest.c : _ ;
252 Main zytest : zytest.c : test tests ;
258 [+] 'clean' now doesn't clean 'Jamrules.auto.configure'; use 'distclean' to kill it
260 [+] JAMCONFIGARGS variable, which collects --* arguments
261 [+] 'config' now understands '--prefix' and sets PREFIX =? xxx
262 [+] InstallUserDefined rule:
263 # $(1): gristed source file
265 # $(3): directory to install
266 # $(LOCATE): the same as $(2) -- can be used in actions
268 [+] -configure-detect-library- now allows additional parameters (allow-any-lib and allow-any-header)
271 [+] *Main now understands some flags, which must be specified after file name:
274 processing.c !no-aliasing # add OPTIM_NOALIAS to build command
276 '!xyz' actually calls rule named --main-option-xyz-- if any, passing GRISTED filename as $(1) and
277 UNMODIFIED file name as $(2). sample no-aliasing rule:
278 rule --main-option-no-aliasing-- {
279 if $(OPTIM_NOALIAS) {
280 CCFLAGS on $(1) += $(OPTIM_NOALIAS) ;
281 C++FLAGS on $(1) += $(OPTIM_NOALIAS) ;
282 OBJCFLAGS on $(1) += $(OPTIM_NOALIAS) ;
285 use '!!filename' if your file name starts with '!'
287 [+] -configure-pkg-config-necessary- rule
288 optional: set PROJECT_NAME to project name which should be displayed on failure
289 -configure-pkg-config-necessary-
290 "GLib" "glib-2.0 >= 2.30.0"
