These events occurred after running update50 and downloading the pset3.zip file.Īnyhow, in general, I've noticed some very specific unexpected behaviour, which is why I couldn't find any solutions elsewhere. Hey there So I’m fairly close to finishing CS50, and I just saw the email notice about the Python-specific course starting in April. What is the default text editor? Is this my imagination? Secondly, wasn't the text editor GUI previously opened using the gedit command at the command line? When I enter "gedit ", I receive a bash error stating that the gedit command isn't found. I have looked through the editor's setting and found nothing relating to the issue. It causes nothing but inconvenience, and feels more like a bug. I still somewhat feel that it could be due to a setting, although it seems unlikely. In most cases, a large amount of the line needs to be deleted or cycled through in order to reach the beginning of a line. This is frustrating, because it means I am unable to directly select text at certain points in order to edit or delete specific statements and identifiers. It's only until the cursor is in the far right of a line does it finally become a text cursor, and able to select and highlight text. Nor can I select the text directly almost as if were a Read-Only file. It remains a normal select cursor, without being able to select the line and consequently edit it. It doesn't seem to latch onto the text unless it is far to the right of the target line. The first odd issue I noticed was related the to the cursor capabilities in a text file. I have, however, searched the settings and the CS50 Discussion boards but to no avail. Of course, they could not be actual issues, and are likely to be due to a latent setting or feature. They were previously unseen and I feel as though they may have occurred due to updates.
isxdigit()Ĭhecks for hexadecimal digits, that is, one of 0 1 2 3 4 5 6 7 8 9 a b c d e f A B C D E F.I've noticed some new issues arise whilst interacting with the CS50 IDE, primarily concerning the text editor. In the "C" and "POSIX" locales, these are: space, form-feed ( '\f'), newline ( '\n'), carriage return ( '\r'), horizontal tab ( '\t'), and vertical tab ( '\v').
isspace()Ĭhecks for white-space characters. ispunct()Ĭhecks for any printable character which is not a space or an alphanumeric character. isprint()Ĭhecks for any printable character including space. islower()Ĭhecks for a lowercase character. isgraph()Ĭhecks for any printable character except space.
isdigit()Ĭhecks for a digit (0 through 9). isblank()Ĭhecks for a blank character that is, a space or a tab. isascii()Ĭhecks whether c is a 7-bit unsigned char value that fits into the ASCII character set. In some locales, there may be additional characters for which isalpha() is true-letters which are neither uppercase nor lowercase. isalpha()Ĭhecks for an alphabetic character in the standard "C" locale, it is equivalent to ( isupper( c ) || islower( c )). isalnum()Ĭhecks for an alphanumeric character it is equivalent to ( isalpha( c ) || isdigit( c )). The list below explains the operation of the functions without the "_l" suffix the functions with the "_l" suffix differ only in using the locale object locale instead of the current locale. The behavior of these functions is undefined if locale is the special locale object LC_GLOBAL_LOCALE (see duplocale(3)) or is not a valid locale object handle. The functions with the "_l" suffix perform the check based on the locale specified by the locale object locale. The functions without the "_l" suffix perform the check based on the current locale. These functions check whether c, which must have the value of an unsigned char or EOF, falls into a certain character class according to the specified locale.
