7.9.1.25.GEL 调试¶
发生运行时错误时，GEL 会输出详细的错误消息以及完整的调用栈。例如：
Test.gel:
foo_cmd2( ) { foo_cmd(); } cmd() { foo_cmd4(); }Test2.gel:
foo_cmd5( ) { foo_cmd2(); } foo_cmd4( ) { foo_cmd7(); }Test3.gel:
foo_cmd7( ) { foo_cmd5(); } foo_cmd() { GEL_TextOut( "address of cmd = %x\n", 0, 0, 0, 0, &cmd2 ); }在 CCS Scripting Console 中评估 cmd()，用户将获得：
js:> eval('cmd()') Error evaluating "cmd()": identifier not found: cmd2 at GEL_TextOut("address of cmd = %x\n", 0, 0, 0, 0, &(cmd2)) [test3.gel:8] at foo_cmd() [test.gel:3] at foo_cmd2() [test2.gel:3] at foo_cmd5() [test3.gel:3] at foo_cmd7() [test2.gel:8] at foo_cmd4() [test.gel:8] at cmd() (C:\ti\ccs\eclipse\configuration\org.eclipse.osgi\bundles\361\1\.cp\resources\debugserver\expression.js#10) js:>7.9.1.25.1.GEL_Trace¶
此功能使用户能够跟踪 GEL 脚本的执行。您可以通过执行 GEL 内置函数 GEL_Trace( level) 来控制该功能
其中 level 是整数 0、1 或 2。
- 0 – 无迹线（默认值）
- 1 – GEL 函数的布线进入/退出
- 2 – 跟踪函数中每个语句的执行情况（包括进入/退出）
默认情况下，布线将被发送到 CCS 控制台。您可以使用 GEL_EnableFileOutput 和 GEL_DisableFileOutput 重定向输出。以下是一些布线示例。
