由 喜欢而已 提交于 2019-12-12 03:30:51
问题 I installed Python 2.7.11 on this Mac, and from terminal Python 2.7.11 can be started. However, From the interpreter of Pycharm (2016.1 version) , there is no Python 2.7.11. Any suggestions ? Thanks PS:I successfully did this on one Mac, but for some reason I cannot make it on another Mac... odd.. 回答1: if you cannot find from the list, you can add it manually, https://www.jetbrains.com/help/pycharm/2016.1/configuring-local-python-interpreters.html?origin=old_help you need to specify the

Implementing operator precedence in my calculator interpreter

由 被刻印的时光 ゝ 提交于 2019-12-12 02:55:09
问题 As part of learning Ruby am trying to implement a basic interpreter which reads input and do basic arithmetic calculations. So far basic arithmetic operations are working but having problem in operator precedence. Which is not handled yet. This is the code. Am at a beginner level. Any mistakes in this code are due to my lack of knowledge. How this code can be modified to handle operator precedence. Sample output 2+2+2 = 6 #correct 10+10/2 = 10 # incorrect as in irb answer must be 15 Github

Why does parser generated by ANTLR reuse context objects?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-12 01:19:29
问题 I'm trying to create an interpreter for a simple programming language using ANTLR. I would like to add the feature of recursion. So far I have implemented the definition and calling functions with option of using several return statements and also local variables. To achieve having local variables I extended the parser partial class of FunctionCallContext with a dictionary for them. I can successfully use them for one time. Also, when I call the same function again from itself (recursively),

Sublime Text Interpreter does not work with GUI

由 末鹿安然 提交于 2019-12-11 12:52:26
问题 I was using sublime text 2 to write some python code, and i configured to use the interpreter for python. So, i noticed that for simple code like this: The interpreter works fine as you can see, after I press: ctrl + B But, when i want to do the same with another that uses Gui code, it does not work, as you can see here: What could be the problem? Am i missing something? Thank you for your time and answers. 回答1: SublimeText's default build systems suppress GUIs in Windows. You can use Console

Is there a portable python interpreter that will run on Mac OS X 10.6 from a USB key?

由 大憨熊 提交于 2019-12-11 11:06:48
问题 I've been running myself ragged trying to find a portable interpreter that I can run from a USB key on my work computer. Work comp is running Mac OS X 10.6, fairly restricted environment, no access to terminal, can't install apps but I do know that portable apps can be run from a USB drive. I've been using shell in a box to serve remote access to my comp at home over the web but out of respect for their network integrity I'd prefer not to. I've also just come across ideone.com which seems

Javascript execution access points in a document

由 五迷三道 提交于 2019-12-11 10:42:14
问题 I'm wondering, where the script interpretation starts in a document with an iframe, that contains another document, with "<header><script>" or possibly "<body><script>" . I just really need to ensure that the execution happens in the "outer" document before the iframe document, but it seems that it is random, is that right ? BTW, what about the order of interpretation of referenced javascripts ? Does it depend on "where" in the document I reference it ? 回答1: I just really need to ensure that

Stop running python script without killing the interpreter

由 烂漫一生 提交于 2019-12-11 09:34:27
问题 Before, I were able to kill a python script started with execfile("somescript.py") while in interpreter by pressing Ctrl + C without killing the interpreter. This would cause a KeyboardInterrupt exception that would stop the script and let me use the interpreter again. However, now (I suspect this came with newer version of python), when I press Ctrl + C while running a script, it sometimes also kills the interpreter, throwing me back to Linux command line. For some reason this doesn't happen

C++ struct member memory allocation

由 谁都会走 提交于 2019-12-11 07:15:51
问题 I have a struct that looks like this: struct rtok { char type; std::string val; bool term; }; I'm writing a simple interpreter and this "rtok" struct is how I represent a token. I have a vector of "rtoks" that I iterate through to generate the parse tree. My question is, if I have 3 members in my struct and I only give a value to 1 member, will the other members still take up memory? What I mean is, if I set "val" equal to "test" would my token take up just 4 bytes or would it take up 6 bytes

Tcl comments: why interpret comments?

由 感情迁移 提交于 2019-12-11 07:12:40
问题 In Tclers wiki page, at 'Dodeklogue' it is mentioned about comments: Comments : If # appears where a command is expected, the rest of the line is a comment. No command execution is attempted, and no characters in the line are interpreted, except that the terminating newline may be escaped with \, signifying that the comment continues on the subsequent line. However, it seems that comments are interpreted byond the terminal \ : for example, let the content of file test.tcl be as below: proc

Extending the Charme Interpreter

由 社会主义新天地 提交于 2019-12-11 06:44:32
问题 I need to extend the Charme interpreter (described here) by adding a primitive procedure <= to the global environment. I know that to do this I also need to define a procedure that implements the primitive, and modify initializeGlobalEnvironment to install the primitive. This is what I have for initializeGlobalEnvironment -- def initializeGlobalEnvironment(): global globalEnvironment globalEnvironment = Environment(None) globalEnvironment.addVariable('true', True) globalEnvironment
