Detailed Description

The Gallery Resource Management class...

Author:

Richard_Millican (Xara Group Ltd) <camelotdev@xara.com>

Date:

18/5/95

Notes: Currently this code uses the GRM file to remember which groups were in which libraries and in which order when quitting the program so than on loading next time we can reflect the old status in the library...

As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required.

BOOL LibSettings::AddLine (  String_256 *  Line, String_256 *  pIniFileString = NULL )  [static]

Adds a single line to the end of the grm file. Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 18/5/95 Parameters: Line  - Line of text to add to file [INPUTS] pIniFileString set to NULL if using default gallery ini file (Default) or to the leafname of the ini file to use [OUTPUTS]  Returns: TRUE if this was successful. Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required.

Notes: This is essentially the same as AddLine but it gives us control of what sections look like. Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required. Definition at line 626 of file sgrmfile.cpp. { ERROR3IF(Section == NULL, "LibSettings::AddSection - not happy with null params"); String_256 Line("["); Line += *Section; Line += "]"; return AddLine(&Line, pIniFileString); }

Call with a pre-created, but not initialised CCDiskFile. After calling this, calls to GetEntryFromFile can be passed this diskfile. When finished, call GetEntryFinish with the DiskFile to De-do all the stuff we done here, like... Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 24/1/96 Parameters: DiskFile  - The DiskFile to use in following GetEntryFromFile calls [INPUTS] pIniFileString set to NULL if using default gallery ini file (Default) or to the leafname of the ini file to use DiskFile  - This will be initialised and opened withe the correct grm file [OUTPUTS] Returns: TRUE if this was successful Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required.

Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 26/1/96 Parameters: TheFile  - Open and seeked lex/disk file [INPUTS] Line  - Will contain the next line (if we return TRUE) [OUTPUTS] Returns: TRUE if this was successful and a line was found and placed in Line. Notes: If we hit a section title, we also return FALSE Definition at line 979 of file sgrmfile.cpp. { BOOL FoundLine = FALSE; BOOL ok = TRUE; TRY { String_256 TokenBuffer; LexTokenType TokType = TOKEN_LINE; while(TokType != TOKEN_EOF && !FoundLine && TheFile->GetLineToken()) { TokType = TheFile->GetTokenType(); if(TokType == TOKEN_LINE) { TokenBuffer = TheFile->GetTokenBuf(); // Check if we've hit a new section name, if so check it and stop the output...

Returns the path and filename for the gallery resource management file... Currently this file holds the groups in the gallery for use when it next starts up... Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 18/5/95 Parameters: pIniFileString  set to NULL if using default gallery ini file (Default) [INPUTS] or to the leafname of the ini file to use PathName  - returns the pathname of the settings file in c:, or wherever [OUTPUTS] Returns: TRUE if successful Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required. Definition at line 879 of file sgrmfile.cpp. { ERROR3IF(PathName == NULL, "LibSettings::GetPathName - not happy with null params"); String_256 GRMFile; // Have a look in the windows directory for our GRM file...

BOOL LibSettings::Init (  void   )  [static]

Value returning initialisation routine... Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 18/5/95 Parameters: [INPUTS]  [OUTPUTS]  Returns: Reimplemented from SimpleCCObject. Definition at line 228 of file sgrmfile.cpp. { return TRUE; }

BOOL LibSettings::IsThisANewSection (  String_256 *  Line, String_256 *  Section )  [static]

Checks if a given line is a new section or not and returns the section name if it is... Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 18/5/95 Parameters: Line  - Line of text to check [INPUTS] Section  - The actual section name itself [OUTPUTS] Returns: TRUE if this line is a new section name Definition at line 652 of file sgrmfile.cpp. { ERROR3IF(Section == NULL, "LibSettings::IsThisANewSection - not happy with null params"); ERROR3IF(Line == NULL, "LibSettings::IsThisANewSection - not happy with null params"); if((Line->Sub((String_8)"[") != -1) && (Line->Sub((String_8)"]") != -1)) { INT32 first = Line->Sub((String_8)"["); INT32 second = Line->Sub((String_8)"]"); if(first < second-1) { Line->Mid(Section, first+1, (second - first)-1); return TRUE; } } return FALSE; }

BOOL LibSettings::NukeSettings (  String_256 *  pIniFileString = NULL  )  [static]

Delete all the settings from the gallery resource file. Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 12/6/95 Parameters: [INPUTS]  [OUTPUTS]  Returns: TRUE if this was successful. This will be called when the user hits 'default' at startup, so the galleries will have to find some other way of working out where their groups are - the ini file for instance, but since this will also have been destroyed, there only remains 1 place - the default static setting - eek ! Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required. Definition at line 844 of file sgrmfile.cpp. { PathName GRMFile; if(LibSettings::GetPathName(&GRMFile, pIniFileString)) { SGLibOil::FileDelete(&GRMFile); return TRUE; } return FALSE; }

BOOL LibSettings::SeekToSection (  CCDiskFile *  TheFile, String_256 *  Section )  [static]

Hunt down our section in the grm file. Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 26/1/96 Parameters: TheFile  - Open lex/disk file (preferably not seeked half way through) [INPUTS] Section - The section we're a'looking for Returns: TRUE if this was successful and we're now seeked to the EOL after the section name Definition at line 1038 of file sgrmfile.cpp. { TRY { String_256 TokenBuffer; LexTokenType TokType = TOKEN_LINE; while(TokType != TOKEN_EOF && TheFile->GetLineToken()) { TokType = TheFile->GetTokenType(); if(TokType == TOKEN_LINE) { TokenBuffer = TheFile->GetTokenBuf(); // Check if we've hit a new section name, if so check it and stop the output... String_256 PossibleSectionName; if(IsThisANewSection(&TokenBuffer, &PossibleSectionName)) { if(PossibleSectionName == *Section) return TRUE; } } } } // See if there was a file io error CATCH(CFileException, e) { // Report the error if no one else did if (Error::GetErrorNumber() != _R(IDN_USER_CANCELLED)) InformError(); else Error::ClearError(); // otherwise remove the error so it won't get reported } END_CATCH return FALSE; }

BOOL LibSettings::StartOutput (  String_256 *  Section, String_256 *  pIniFileString = NULL )  [static]

Checks if there's already a grm file on the disk. If so, create a new .bak file holding copies of all the sections (except the one specified), then copy this new file over the old .grm file. Author: Richard_Millican (Xara Group Ltd) <camelotdev@xara.com> Date: 18/5/95 Parameters: Section  - The section we're about to add [INPUTS] pIniFileString set to NULL if using default gallery ini file (Default) or to the leafname of the ini file to use [OUTPUTS]  Returns: TRUE if this was successful. Doing this means that future calls to AddLine will append the information to the end of the grm file, and there won't be any duplication. Notes: This avoids the old system of sending a message around all the galleries, and also means that unopened galleries don't need to store a list of their groups. Also, if there's a crisis, the old grm file is still on the disk... Notes: As this is fairly general read and write ini file code, then this has been expanded so that an option other ini file name can be specified. If this is specified then this will be used instead of the GRM file name. Added by Neville 14/1/97 for saving/loading paths for plug-ins as the main ini file code cannot cope with the concept of sections filled with an arbitrary number of items which need cleaning out when resaving to remove old items no longer required.
